== install git/scripts ==
== enable outgoing email (debian 11) ==
 
this is different from ubuntu 20. it uses /etc/mailname and it hardwires the hostname into main.cf.
 
== enable outgoing email ==
 
we have an unusual email configuration. outgoing email should work to deliver error messages, notices, etc. incoming email is disabled, we do not receive email for local users.
 
this causes problems with TRIUMF smtp server. if our message cannot be delivered (wrong email address or receipient computer is turned off), TRIUMF smtp server will generate a delivery failure notification email and try to send it to the "from" address of the failed message. but the "from" address does not receive any email, so another delivery failure  notification email is generated and an attempt to deliver it. which again fails, rinse and repeat.
 
as solution, kray created a special rule, email from scrap.triumf.ca does not generate delivery failure notices. failed messages sit in the queue for 5 days, then they are deleted. (K.O. - confirmed with kray 3jan2024).
 
to make this work we use the msmtp MTA package.

<pre>
<pre>

== install gonodeinfo ==
== disable apparmor ==
 
On NFS-Root network booted machines!
 
If "man man" returns "permission denied" and syslog reports apparmor "sendmsg DENIED" errors, disable apparmor. This is supposedly fixed in kernel 6.0 and later (to be confirmed), see https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1784499
 
Disable apparmor, see https://ubuntu.com/server/docs/security-apparmor
 
This takes effect after a reboot.


* go to https://bitbucket.org/dd1/gonodeinfo follow instructions:
<pre>
<pre>
yes | apt-get -y install golang

</pre>
* edit /etc/gonodeinfo.conf
* change "Description", "Location", "User" and "Administrator" as appropriate (or delete them)
* change "Servers" to read: Servers: ladd00.triumf.ca:8601
* run gonodeinfo
* if error is "connection refused". go to the nodeinfo server to add this client to the access control list:
* on the gonodeinfo server: run gonodereceive -a daq13
* try gonodeinfo again, there should be no error
* on the gonodeinfo server: run gonodereport, look at the web pages, the new machine should be listed now

Second, configure certbot:


(Note: as of 2018-01-18 certbot requires use of http port 80 to get the initial https certificate,
= NIS master =
renewal can continue to use the https port 443)
 
notes for setting up the NIS master
 
== wheel user ==
 
"wheel" is the default administrative user. We do not want it's password exported to NIS (encrypted password hash is world visible) and we do not want it's home directory exported to NFS (~wheel/.ssh is world visible and potentially writable: anybody can change ~wheel/.ssh/authorized_keys).
 
* move wheel's home directory from /home/wheel to /wheel (see special section about this)
* change wheel's UID and GID from 1000 to a value below MINUID in /var/yp/Makefile
 
== coherent uids ==
 
we do not want system accounts defined in /etc/passwd of the NIS master
to be included in the NIS map "passwd". this causes trouble on NIS clients
where newly installed packages fail to create local system users because same
user already exists in NIS.
 
This is controlled by MINUID in /var/yp/Makefile.
 
Historical TRIUMF uids start from around 200, but several clusters do not have any historic TRIUMF uids below 500 and MINUID is set to:
* DAQ-NIS: MINUID=200
* ISAC-NIS: MINUID=500
* TITAN-NIS: MINUID=500
* MUSR-NIS: MINUID=500
* TIG-NIS: MINUID=500 (100 on SL6 mother8pi)
 
Ubuntu 20 has two programs to create users:
* adduser - creates new users with UID 1000 and up as specified in /etc/adduser.conf. No problems here.
* adduser --system - creates new system users with UID 100 and up as specified in /etc/adduser.conf. No problems here.
* useradd - creates new users with UID 1000 and up as specified in /etc/login.defs. No problems here.
* useradd --system - creates new system users with UID 999 and down (read "man useradd", section at the end about SYS_UID_MAX). This collides with NIS MINUID, these system users will be included in the NIS map and cause trouble.
 
This problem cannot be fixed, SYS_UID_MIN, SYS_UID_MAX and UID_MIN in /etc/login.defs do not seem
to have any effect on UIDs chosen by "useradd --system". (tested on Ubuntu LTS 20.04).


(Note: as of 2019-01-?? certbot requires use of port 80 for renewals)
So far only these system accounts seem to be affected by this:
* systemd-coredump
* ganglia


* check that port 80 is not used by anything:
To fix:
* netstat -an | grep LISTEN | grep ^tcp | grep 80
* run "sort -r -n -t: -k3 /etc/passwd" to identify the last unused system user uid (range 100..200)
* lsof -P | grep -i tcp | grep LISTEN | grep 80
* run "sort -r -n -t: -k3 /etc/group" to identify the last unused system user gid (range 100.200)
* if lsof reports that apache2 is listening on port 80, follow the apache2 instructions above (remove "listen 80" from apache2.conf
* systemd-coredump: manually change UID and GID (package systemd-coredump is usually not installed)
* ganglia: same thing, then change ownership on all ganglia files.
 
Also read systemd author's opinion on system vs user UIDs:

** you should see a request for password (do not login yet)
** if you get "connection refused", HTTPS port 443 may need to be enabled in the local firewall, look at documentation for ufw.
Second, configure certbot:


=== AMD 3700X ===
(Note: as of 2018-01-18 certbot requires use of http port 80 to get the initial https certificate,
renewal can continue to use the https port 443)


(memory is non-ECC)
(Note: as of 2019-01-?? certbot requires use of port 80 for renewals)

from the machine where you are running the web browser (i.e. google-chrome), run (replace trinat@trinatdaq with the username and machine name where you started jupyter)
open a new shell and run: ssh -v trinat@trinatdaq -L 8888:localhost:8888
in the web browser, open http://localhost:8888
this gives us the login page
in the password or token entry field, put the token from the "tree?token=xxx" above (printed by jupyter on startup)
push button "login"

== Steps to do ==
=== daq00 ===


* assign network numbers to the private network, i.e. 192.168.1.x, 192.168.2.x, etc
per https://serverpilot.io/docs/how-to-upgrade-ubuntu-20.04-to-22.04/
* (on the gateway machine, each private network interface has to have a different network number)
* (each network interface can have multiple networks attached, via VLANs or via eth0:0, eth0:1 constructs)
* assign IP addresses on the private network, save them in /etc/hosts i.e. "hvps 192.168.1.10"
* (for simplicity, assign 192.168.1.1 to the gateway machine itself)
* (IP addresses 192.168.1.0 and 192.168.1.255 are "special", do not use them)
* setup DNS server (dnsmasq) to serve contents of /etc/hosts via DNS (otherwise, many programs will see inconsistent name to IP address mapping)
* setup DHCP server (ISC dhcpd or dnsmasq) to give out the IP addresses
* setup tftp, pxelinux and NFS for diskless booting
* setup time server (chronyd) to provide common time to all devices
* setup NAT so machines on private network can access the internet (to get OS updates, etc)
* setup NIS and NFS so machines on the private network can use common home directories
* setup rsync backup of machines on the private network


== setup hosts ==
* edit /etc/hosts
<pre>
<pre>
192.168.1.101 dsfe01
do-release-upgrade -f DistUpgradeViewNonInteractive
... and so forth
</pre>
</pre>


== setup dns and dhcp ==
if it exists "too soon" without doing anything, run it without "-f xxx", most likely it does not like something about this machine. in case of daq00 it did not like how the EFI partitions were mounted. after fixing it, non-interactive upgrade was successful.

= Convert from single to dual mirrored ZFS SSD =


NAT allows machines on the private network to connect to the internet: https://en.wikipedia.org/wiki/Network_address_translation
Assuming Ubuntu LTS 22.04 with "instal on ZFS" option, we will
add a second SSD, configure ZFS to use both SSDs in mirrored
configuration and setup grub to boot from either SSD. This
is intended to create a full redundant system where failure
of either SSD does not break the system.

If both SSDs are identical size, use this simpler method of duplicating the partition table:
<pre>
<pre>
# /etc/rc.local

root@midm9b:~# grep -v ^label-id part_table | sed -e 's/, *uuid=[0-9A-F-]*//' | sfdisk /dev/sdb
</pre>
The grep and sed in the second command are there to prevent disk ID and partition IDs from being cloned. Alternatively the part_table file can be edited manually to remove the label-id line and the uuid entries from the individual partitions.

= Disable NetworkManager =
 
NOTE: THIS IS BROKEN IN UBUNTU LTS 22.04
 
NetworkManager is useful for configuring dynamic
network interfaces, i.e. laptops that often move
between networks, or connect to multiple choice
of wifi networks, etc.
 
For machines with statically configured network interfaces,
NetworkManager is not necessary.
 
As it has been observed to become confused and observed
to malfunction when network links go up and down (it keeps
unnecessarily reconfiguring the ip address, etc), it can
be usefuil to disable it.
 
* list all network interfaces
<pre>
# /bin/ls -1 /sys/class/net/
enp0s31f6
lo
</pre>
* edit /etc/network/interfaces:
<pre>
rename enp0s31f6=eth0
auto eth0
iface eth0 inet static
  address 142.90.120.94/19
  gateway 142.90.100.18
</pre>
* statically configure systemd-resolved
** create /etc/systemd/resolved.conf.d/resolved.conf with this contents:
<pre>
[Resolve]
DNS=142.90.100.19
Domains=triumf.ca
</pre>
** systemctl restart systemd-resolved
** resolvectl
** systemd-analyze cat-config systemd/resolved.conf

* http://www.triumf.info/wiki/DAQwiki/index.php/Dhcpd_on_eth1
 
== Steps to do ==
 
!!! UPDATED 16feb2024 Ubuntu-22.04.03 !!!
 
* assign network numbers to the private network, i.e. 192.168.1.x, 192.168.2.x, etc
* (on the gateway machine, each private network interface has to have a different network number)
* (each network interface can have multiple networks attached, via VLANs or via eth0:0, eth0:1 constructs)
* assign IP addresses on the private network, save them in /etc/hosts i.e. "hvps 192.168.1.10"
* (for simplicity, assign 192.168.1.1 to the gateway machine itself)
* (IP addresses 192.168.1.0 and 192.168.1.255 are "special", do not use them)
* setup DNS server (dnsmasq) to serve contents of /etc/hosts via DNS (otherwise, many programs will see inconsistent name to IP address mapping)
* setup DHCP server (dnsmasq) to give out the IP addresses
* setup TFTP server (dnsmasq), pxelinux and NFS for diskless booting
* setup time server (chronyd) to provide common time to all devices
* setup NAT so machines on private network can access the internet (to get OS updates, etc)
* setup NIS and NFS so machines on the private network can use common home directories
* setup rsync backup of machines on the private network
 
== setup hosts ==
 
* edit /etc/hosts
<pre>
192.168.1.101 dsfe01
... and so forth
</pre>
 
== setup dns and dhcp ==
 
!!! updated 16feb2024 for Ubuntu 22.04.3 !!!
 
!!! note: stock systemd-resolved remains, is configured to forward queries to dnsmasq, configured to forward queries to TRIUMF DNS !!!
 
!!! note: per authors of systemd, bare hostnames are not permitted, a DNS domain name must always be used. DNS domain name "dsdaq" is used in this example !!!
 
* apt install dnsmasq
* ensure dnsmasq starts after all interfaces are up (Ubuntu-22)

mkdir /etc/systemd/system/dnsmasq.service.d

Prerequisites

  • before setting up new machine run memory test
  • prepare flash drive with free version of memtest86: https://www.memtest86.com
  • test boot from flash drive, test takes ~ few hours
  • test will end with summary page, if passed continue with Ubuntu
  • number that might be worth noting is memory latency

Ubuntu version

lsb_release -a
uname -a

Ubuntu installer

  • updated for Ububtu LTS 20.04.01, 22.04.1, 24.04 (only minor differences)
  • download the latest Ubuntu LTS desktop installer iso image
  • dd the image to a USB key
  • power down, disconnect all disks (all HDDs, all SSDs, all M.2)
  • connect the SSD to be used as system disk
  • if system will use mirrored SSDs (using ZFS mirror), leave second SSD disconnected, we will activate it later
  • power up
  • boot from USB key in legacy mode or UEFI mode (select this in the BIOS boot menu - F8 for ASUS, F11 for Supermicro)
  • follow the instruction:
  • "try ubuntu or install ubuntu" - choose "install"
  • select language - accept default
  • "updates and other software" - accept default settings ("normal install")
  • "installation type" - select "advanced features" and "experimental: use ZFS"
  • accept partition choice
  • "where are you?" - select "Vancouver" (PST time zone)
  • "who are you?" - leave all fields blank, except "username" set to "wheel", "password" set to the root password. hostname will be set later after configuring the network
  • don't install third party sw
  • installation runs in a few minutes, when finished, reboot
  • login as user wheel
  • answer annouying questions:
  • "livepatch" - say "next"
  • "help improve" - select "do not send", say "next"
  • "privacy" - leave "location" as "off", say "next"
  • "ready to go", say "done"
  • right-click on the desktop, say "open in terminal", a shell will open
  • say "sudo /bin/bash", enter the root password, you now have the root shell
  • run nm-connection-editor to configure the network. use netmask 255.255.224.0, gateway 142.90.100.18, DNS 142.90.100.19, search path "triumf.ca"
  • after network is up (can ping ladd00), continue with post-installation steps below

Install instructions

prepare

apt update
apt upgrade

install ssh

apt install ssh

install git/scripts

apt -y install git
mkdir ~root/git
cd ~root/git
git clone https://daq00.triumf.ca/~olchansk/git/scripts.git
cd scripts
git pull

configure hostname

vi /etc/hostname

disable swap

ubuntu installer creates a 2 GB swap partition, not useful on 32-64 GB machine, disable it: 

vi /etc/fstab ### comment out the "swap" line

maybe reboot

this is a good point to reboot the machine to boot the latest kernel and to set the correct hostname

install etckeeper

keep contents of /etc in a git repository: 

apt -y install etckeeper

set timezone

timedatectl list-timezones | grep -i vancouver
timedatectl set-timezone America/Vancouver

install time synchronization

apt -y install chrony
#echo server time1.triumf.ca iburst >> /etc/chrony/chrony.conf
#echo server time2.triumf.ca iburst >> /etc/chrony/chrony.conf
#echo server time3.triumf.ca iburst >> /etc/chrony/chrony.conf
cd ~/git/scripts
git pull
cd ~
cp ~/git/scripts/etc/triumf.sources /etc/chrony/sources.d/
systemctl disable systemd-timesyncd.service
systemctl stop systemd-timesyncd.service
systemctl disable ntp
systemctl stop ntp
systemctl enable chrony
systemctl restart chrony
chronyc sources
chronyc tracking

NOTE1: if time1, time2, time3 are already listed in /etc/crony/chrony.conf, please remove them and restart chrony.

NOTE2: if time1, time2, time3 are not listed in "chronyc tracking" or if they are not selected by "chronyc tracking", check that /etc/crony/chrony.conf contains "sourcedir /etc/chrony/sources.d", see NOTE4.

NOTE3: read https://chrony-project.org/faq.html#_should_i_prefer_chrony_over_timesyncd_if_i_do_not_need_to_run_a_server

NOTE4: update very old chrony config file, remove chrony, than install it from scratch as above 

grep sourcedir /etc/chrony/chrony.conf ### if we have it, we are good
apt remove chrony
apt purge chrony

reenable systemd-timesyncd

ONLY IF CHRONY DOES NOT WORK

To configure systemd-timesyncd, set "NTP=" in /etc/systemd/timesyncd.conf 

apt remove chrony
cat /etc/systemd/timesyncd.conf
systemctl enable systemd-timesyncd.service
systemctl restart systemd-timesyncd.service
systemctl status systemd-timesyncd.service
timedatectl status
timedatectl timesync-status

enable outgoing email (debian 11)

this is different from ubuntu 20. it uses /etc/mailname and it hardwires the hostname into main.cf.

enable outgoing email

we have an unusual email configuration. outgoing email should work to deliver error messages, notices, etc. incoming email is disabled, we do not receive email for local users.

this causes problems with TRIUMF smtp server. if our message cannot be delivered (wrong email address or receipient computer is turned off), TRIUMF smtp server will generate a delivery failure notification email and try to send it to the "from" address of the failed message. but the "from" address does not receive any email, so another delivery failure notification email is generated and an attempt to deliver it. which again fails, rinse and repeat.

as solution, kray created a special rule, email from scrap.triumf.ca does not generate delivery failure notices. failed messages sit in the queue for 5 days, then they are deleted. (K.O. - confirmed with kray 3jan2024).

to make this work we use the msmtp MTA package. 

cd ~
apt -y remove postfix
apt -y purge postfix # remove old config files
apt -y install mailutils msmtp msmtp-mta # say "no" to apparmor support
apt -y install bsd-mailx
cd ~/git/scripts/etc
git pull
/bin/cp -fv aliases /etc/aliases
/bin/cp -fv msmtprc /etc/msmtprc
/bin/rm -vf ~root/.forward
/bin/rm -vf /etc/mailname
Mail root
Subject: test
test
^D
CC: <CR>

enable outgoing email (postfix)

THIS IS OBSOLETE!!!

  • TRIUMF: use smtp.triumf.ca
  • CERN: use cernmx.cern.ch
apt install postfix ### select "satellite system", enter full hostname "xxx.triumf.ca", enter "smtp.triumf.ca"
apt install mailutils
dpkg-reconfigure postfix ### (if postfix already installed)

echo olchansk@triumf.ca lindner@triumf.ca bsmith@triumf.ca >> ~root/.forward
mailx root
test
^D

enable ping for all users (debian 11)

Without this tweak, Debian will report "operation not permitted" if a user tries to ping somewhere. 

echo 'net.ipv4.ping_group_range = 0 1000' > /etc/sysctl.d/99-ping.conf

disable apparmor

On NFS-Root network booted machines!

If "man man" returns "permission denied" and syslog reports apparmor "sendmsg DENIED" errors, disable apparmor. This is supposedly fixed in kernel 6.0 and later (to be confirmed), see https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1784499

Disable apparmor, see https://ubuntu.com/server/docs/security-apparmor

This takes effect after a reboot. 

systemctl stop apparmor.service
systemctl disable apparmor.service

disable swap (debian 11)

  • on 64 GB RAM machines swap is not useful
  • on machines booted from network (NFS-ROOT), swap does not work
  • on machines running from flash (RPi, etc), flash is too slow for useful swap
  • swap configured by linux installers invariably has wrong size and is not useful
systemctl disable dphys-swapfile
systemctl stop dphys-swapfile
dphys-swapfile uninstall

  • edit /etc/gonodeinfo.conf
  • change "Description", "Location", "User" and "Administrator" as appropriate (or delete them)
  • change "Servers" to read: Servers: daq00.triumf.ca:8601
  • run "gonodeinfo -v"
  • if error is "connection refused". go to the nodeinfo server to add this client to the access control list:
  • on the gonodeinfo server: run /opt/gonodeinfo/gonodereceive.exe -a daq13
  • try gonodeinfo again, there should be no error
  • on the gonodeinfo server: run gonodereport, look at the web pages, the new machine should be listed now

install fonts for EPICS

  • apt install xfonts-100dpi xfonts-75dpi
  • restart Xorg (i.e. "killall Xorg", this will log you out from the console)
  • xlsfonts | grep -i helvetica ### should show fonts with different sizes, not just size 0 (scalable)

As far as I know, only needed for BNMR/BNQR 

apt install wine winetricks

install lightdm

unlike the default gdm login manager, lightdm shows the machine hostname and does not require an extra mouse click to swicth from screen saver to login mode. 

apt -y install lightdm
# select lightdm

install desktop environments

note: default display manager and default desktop are deficient, please do not skip this step.

note: if apt asks to choose the display manager, select "lightdm"

note: KO - I recommend the "MATE" desktop.

note: you will have to cut-and-paste this several times because "apt" eats commands, even with "-y" and even piped from "yes".

install ROOT

Please install ROOT per instructions at https://root.cern.ch.

NOTE1: The ROOT package available from Ubuntu repositories is severely out of date and cannot be used with MIDAS and ROOTANA. ### DO NOT DO THIS! apt-get install root-system

NOTE2: as of 2017-Jan-09, ROOT binary kits for Ubuntu do not work (use GCC 5 instead of GCC6), build from source instead.

Install x2go

apt-get update

disable ssh access from outside of TRIUMF

to stop ssh login spam, disable ssh access from outside of TRIUMF. this can be done by requesting a firewall block through the helpdesk or by local firewall rule: 

echo iptables -I INPUT ! -s 142.90.0.0/255.255.0.0 -p tcp --dport 22 -j REJECT >> /etc/rc.local
/etc/rc.local

install smart-status

ln -s ~/git/scripts/smart-status/smart-status.perl ~root/

enable boot menu and boot messages

This will enable the grub menu (with a 10 sec timeout) and replace black screen with exciting linux boot messages.

  • emacs -nw /etc/default/grub
GRUB_DEFAULT=0
#GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10

GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""
#GRUB_GFXMODE=640x480
  • update grub config:
grub-mkconfig -o /boot/grub/grub.cfg

reboot

this completes installation of the base system.

following sections modify basic ubuntu to fix known problems and to enable special stuff.

  • test: unattended-upgrade --dry-run -v

NOTE: update-on-shutdown is disabled.

NOTE: there is no update-on-boot, but:

NOTE: if machine was off for a long time, the systemd update timer would have expired and it will fire soon after reboot, causing an automatic update run. this is unwanted, and there is no fix or workaround for it. K.O. June-2023.

Fix bpool is full (obsolete)

THIS IS CAUSED BY OBSOLETE PACKAGE zsys. PLEASE: apt remove zsys

!!! only if ROOT on ZFS !!!

There is an error in the zsys package that causes bpool to run out of space, see #Ubuntu zsys for more details.

To fix: 

cd ~/git/scripts
git pull
cp etc/zsys.conf /etc/
zsysctl service reload
zsysctl service gc
zpool list bpool
zfs list bpool
df /boot

IPMI instructions

IPMI is the board management hardware on Supermicro and other server motherboards. This includes hardware sensors - fan rotation speed, temperatures and power supply voltages. 

apt-get install ipmitool
systemctl enable ipmievd
systemctl restart ipmievd

Run:

  • ipmitool sel list ### event list
  • ipmitool sel elist ### event list
  • ipmitool sel clear ### clear event list (if it becomes full)
  • ipmitool sensor ### report hardware sensors

move /home/wheel

note: this MUST be done if ZFS root and NIS/autofs with /home.

Default location of wheel's home directory will collide with autofs /home, it has to be moved, for example to /wheel. 

# logout from the wheel user
# go to another computer
ssh root@daqubuntuxxx
zfs list | grep wheel ### identify zfs name wheel_xxxxxx
#zfs set mountpoint=/wheel rpool/USERDATA/wheel_hm8fzh
zfs set mountpoint=/wheel `zfs list | grep wheel | cut -f1 -d" "`
zfs list | grep wheel
emacs -nw /etc/passwd ### change wheel's home directory from /home/wheel to /wheel
su - wheel ### check that user wheel still works

This will break wheel's ability to run snap programs, such as firefox, install chrome as listed below.

enable NIS (ubuntu 22.04, 24.04, debian 11, 12)

apt -y install rpcbind nis
echo DAQ-NIS >> /etc/defaultdomain

NIS master

notes for setting up the NIS master

wheel user

"wheel" is the default administrative user. We do not want it's password exported to NIS (encrypted password hash is world visible) and we do not want it's home directory exported to NFS (~wheel/.ssh is world visible and potentially writable: anybody can change ~wheel/.ssh/authorized_keys).

  • move wheel's home directory from /home/wheel to /wheel (see special section about this)
  • change wheel's UID and GID from 1000 to a value below MINUID in /var/yp/Makefile

coherent uids

we do not want system accounts defined in /etc/passwd of the NIS master to be included in the NIS map "passwd". this causes trouble on NIS clients where newly installed packages fail to create local system users because same user already exists in NIS.

This is controlled by MINUID in /var/yp/Makefile.

Historical TRIUMF uids start from around 200, but several clusters do not have any historic TRIUMF uids below 500 and MINUID is set to:

  • DAQ-NIS: MINUID=200
  • ISAC-NIS: MINUID=500
  • TITAN-NIS: MINUID=500
  • MUSR-NIS: MINUID=500
  • TIG-NIS: MINUID=500 (100 on SL6 mother8pi)

Ubuntu 20 has two programs to create users:

  • adduser - creates new users with UID 1000 and up as specified in /etc/adduser.conf. No problems here.
  • adduser --system - creates new system users with UID 100 and up as specified in /etc/adduser.conf. No problems here.
  • useradd - creates new users with UID 1000 and up as specified in /etc/login.defs. No problems here.
  • useradd --system - creates new system users with UID 999 and down (read "man useradd", section at the end about SYS_UID_MAX). This collides with NIS MINUID, these system users will be included in the NIS map and cause trouble.

This problem cannot be fixed, SYS_UID_MIN, SYS_UID_MAX and UID_MIN in /etc/login.defs do not seem to have any effect on UIDs chosen by "useradd --system". (tested on Ubuntu LTS 20.04).

So far only these system accounts seem to be affected by this:

  • systemd-coredump
  • ganglia

To fix:

  • run "sort -r -n -t: -k3 /etc/passwd" to identify the last unused system user uid (range 100..200)
  • run "sort -r -n -t: -k3 /etc/group" to identify the last unused system user gid (range 100.200)
  • systemd-coredump: manually change UID and GID (package systemd-coredump is usually not installed)
  • ganglia: same thing, then change ownership on all ganglia files.

Also read systemd author's opinion on system vs user UIDs: https://github.com/systemd/systemd/issues/4850#issuecomment-265698275

Fix systemd-logind NIS breakage

!!! THIS IS NOT NEEDED FOR UBUNTU LTS 20.04 !!!

there is a delay in ssh logins for normal users. "ssh -v" shows the delay is after "pledge...". this fix removes the delay.

systemd developers think that we should not use NIS and made sure there are problems if we do. To give them credit, they do offer a workaround. Read this: https://github.com/poettering/systemd/commit/695fe4078f0df6564a1be1c4a6a9e8a640d23b67 

mkdir /etc/systemd/system/systemd-logind.service.d
echo -e "[Service]\nIPAddressDeny=\n" > /etc/systemd/system/systemd-logind.service.d/local.conf
systemctl daemon-reload
systemctl cat systemd-logind.service

Fix systemd-udevd NIS breakage

see same problem as above with udev getting stuck. ubuntu lts 20.04. 

mkdir /etc/systemd/system/systemd-udevd.service.d
echo -e "[Service]\nIPAddressDeny=\n" > /etc/systemd/system/systemd-udevd.service.d/local.conf
systemctl daemon-reload

Enable rc.local

For reasons unknown, Ubuntu LTS 20.04 does not enable /etc/rc.local. Do this: 

cd ~/git/scripts
git pull
cp -n -v etc/rc.local /etc/
chmod a+rx /etc/rc.local
cp etc/rc-local.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable rc-local
systemctl start rc-local
systemctl status rc-local

Remove unwanted packages

apt remove bash-completion # broken, adds unwanted "\" if "ls -l $ROOTSYS/<tab>"
apt remove zsys # broken, do not use
apt remove sddm # login manager
apt remove avahi-daemon avahi-autoipd # not sure what it does, observed using 100% CPU
apt remove modemmanager # probes all serial ports to see if it's a modem

Disable unwanted services

systemctl disable mpd
systemctl disable snapd
systemctl disable ModemManager
systemctl --global mask tracker-extract-3.service
systemctl --global mask tracker-miner-fs-3.service
systemctl daemon-reload

Disable sleep and suspend

note: we see some computers randomly shutdown or go to sleep, log files indicates the "sleep" or "suspend" button was pushed by user, but no such buttons actually exist. this is the fix for this: 

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target systemd-suspend.service systemd-hybrid-sleep.service

Enable crontab @reboot for MIDAS

startup scripts have a bug - cron @reboot entries for normal users can run before autofs is ready, so if the home directory is on autofs/NFS, it cannot be accessed and the cron job fails. If MIDAS is supposed to be started by cron @reboot, it will not start (there *will* be an error message in /var/log/cron). 

mkdir /etc/systemd/system/cron.service.d
echo -e "[Unit]\nAfter=ypbind.service autofs.service\n" > /etc/systemd/system/cron.service.d/local.conf
systemctl daemon-reload
systemctl cat cron.service

Explore the systemd dependency tree using "systemctl list-dependencies" maybe with "--all".

Visualize the exact boot sequence from previous boot: "systemd-analyze plot > xxx.svg", look at the svg file using a web browser.

Crontab entry to start midas: (install in the midas user crontab, not root crontab) 

su - midasuser
crontab -l
#@reboot /bin/bash -l -c "/home/trinat/bin/start-daq-applications"
#@reboot /bin/tcsh -c "/home/trinat/bin/start-daq-applications"

Install apache httpd proxy for midas and elog

This will configure the HTTPS/SSL certificate using "certbot" and "letsencrypt" and configure an HTTPS web server using apache2.

First, configure apache2:

  • execute these commands:
apt -y install apache2
cd /etc/apache2
  • create new file conf-available/ssl-daq14.conf # use actual hostname instead of daq14
SSLSessionCache         shmcb:/run/httpd/sslcache(512000)
SSLSessionCacheTimeout  300
SSLRandomSeed startup file:/dev/urandom  256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin
  • create new file sites-available/daq14-ssl.conf # use actual hostname instead of daq14
<IfModule mod_ssl.c>
    <VirtualHost *:443>
        ServerName daq14.triumf.ca
        DocumentRoot /var/www/html
        ErrorLog /var/log/apache2/daq14.log
        SSLEngine on
        # note SSLProtocol, SSLCipherSuite and some other settings are overwritten by /etc/letsencrypt/options-ssl-apache.conf
        SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
        SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5:!SEED:!IDEA:!RC4
        ## use port specified in elogd.cfg
        #ProxyPass /elog/ http://localhost:8082/ retry=1 
        ## use mhttpd port
        #ProxyPass /      http://localhost:8080/ retry=1 
        Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
        <Location />
            SSLRequireSSL
            AuthType Basic
            AuthName "DAQ password protected site"
            Require valid-user
            # create password file: touch /etc/apache2/htpasswd
            # to add new user or change password: htpasswd /etc/apache2/htpasswd username
            AuthUserFile /etc/apache2/htpasswd
        </Location>
    </VirtualHost>
</IfModule>
  • stop apache2 from listening on port 80: edit /etc/apache2/ports.conf, comment-out the line "Listen 80"
  • stop apache2 from listening on port 80: edit /etc/apache2/ports.conf, comment-out the line "Listen 80"
  • enable ssl module
  • enable new configurations
a2enmod ssl
a2enmod headers
a2enmod proxy
a2enmod proxy_http
a2enconf ssl-daq14
a2ensite daq14-ssl
  • disable default ssl sites
a2dissite 000-default-le-ssl
a2dissite 000-default
ls -l /etc/apache2/sites-enabled/ ### should show only daq14-ssl.conf
  • check that there are no syntax problems
apache2ctl configtest
  • enable and start apache2:
systemctl enable apache2
systemctl restart apache2
systemctl status apache2
  • apache2 may fail to start, look in /var/log/apache2/error.log and /var/log/apache2/daq14.log
  • if it says "Failed to configure ... certificate", proceed to the step for setting certbot.
  • try to access https://daq14.triumf.ca
    • you should see a complaint about self-signed certificate
    • you should see a request for password (do not login yet)
    • if you get "connection refused", HTTPS port 443 may need to be enabled in the local firewall, look at documentation for ufw.

Second, configure certbot:

(Note: as of 2018-01-18 certbot requires use of http port 80 to get the initial https certificate, renewal can continue to use the https port 443)

(Note: as of 2019-01-?? certbot requires use of port 80 for renewals)

(Note: unsurprisingly, this requires outside access to connect with letsencrypt, so won't work if PC is only accessible from on-site network)

  • check that port 80 is not used by anything:
  • netstat -an | grep LISTEN | grep ^tcp | grep 80
  • lsof -P | grep -i tcp | grep LISTEN | grep 80
  • if lsof reports that apache2 is listening on port 80, follow the apache2 instructions above (remove "listen 80" from apache2.conf
  • install certbot (if necessary open tcp port 80 in the firewall, see documentation for ufw):
apt install certbot python3-certbot-apache
certbot certonly --standalone --installer apache
  • then answer questions:
  • "activate HTTPS for daq14.triumf.ca" - say ok
  • "enter email address" - enter your own email address
  • "please read terms..." - read the terms and say "agree"
  • it will take a few moments...
  • "congratulations..." - say ok.
certbot install --apache --cert-name daq14.triumf.ca
  • then answer questions:
  • "choose redirect..." - say "1" (no redirect)
  • look inside /etc/apache2/sites-enabled/daq14-ssl.conf to see that SSLCertificateFile & co point to certbot certificates in

/etc/letsencrypt/live/daq14.triumf.ca/

  • to check current renewal and to update the certbot config file in /etc/letsencrypt/renewal, run this:
certbot renew --standalone --installer apache --force-renewal

NOTE: this certificate will expire in 3 months, automatic renewal should work with current version of certbot

Third, activate password protection:

  • as shown in the config file above, create password file and initial user: (replace "midas" with specific username)
touch /etc/apache2/htpasswd
htpasswd /etc/apache2/htpasswd midas
  • restart apache2
systemctl restart apache2
systemctl status apache2

From here:

  • enable proxy for MIDAS mhttpd - uncomment redirect in the config file above
  • enable proxy for ELOG - ditto
a2enmod proxy
a2enmod proxy_http
apache2ctl configtest
systemctl restart apache2

SSL                  = 0

NOTE: if certbot fails with errors about 'module' object has no attribute 'pyopenssl', try this: pip install requests==2.6.0

Enable core dumps

By default, Ubuntu LTS 20.04 installs the apport package which disabled core dumps from user applications. (google it up!). It is not meant to do this and documentation claims that it is not installed and not enabled by default. Oh, well... 

apt remove apport
apt autoremove ### will remove apport-symptoms and a few other packages

After this, core dumps are written to file "core" in the current directory. See /proc/sys/kernel/core_pattern and /proc/sys/kernel/core_uses_pid.

Enable core dump file names to include process id, add following to /etc/rc.local 

echo 1 > /proc/sys/kernel/core_uses_pid

Enable debugger

By default, Ubuntu LTS 20.04 does not permit debugger to attach and debug already running programs. To enable it, add following to /etc/rc.local 

echo 0 > /proc/sys/kernel/yama/ptrace_scope

Convert from single to dual mirrored ZFS SSD

Assuming Ubuntu LTS 22.04 with "instal on ZFS" option, we will add a second SSD, configure ZFS to use both SSDs in mirrored configuration and setup grub to boot from either SSD. This is intended to create a full redundant system where failure of either SSD does not break the system.

  • identify first SSD

  • if second SSD is not autodetected, reboot
  • Clone partition table automatically

If both SSDs are identical size, use this simpler method of duplicating the partition table: 

root@midm9b:~# sfdisk -d /dev/sda > part_table
root@midm9b:~# grep -v ^label-id part_table | sed -e 's/, *uuid=[0-9A-F-]*//' | sfdisk /dev/sdb

The grep and sed in the second command are there to prevent disk ID and partition IDs from being cloned. Alternatively the part_table file can be edited manually to remove the label-id line and the uuid entries from the individual partitions.

  • Clone partition table manually (e.g. for different size disks)
  • list partition table of first SSD:

Disable NetworkManager

NOTE: THIS IS BROKEN IN UBUNTU LTS 22.04

NetworkManager is useful for configuring dynamic network interfaces, i.e. laptops that often move between networks, or connect to multiple choice of wifi networks, etc.

For machines with statically configured network interfaces, NetworkManager is not necessary.

As it has been observed to become confused and observed to malfunction when network links go up and down (it keeps unnecessarily reconfiguring the ip address, etc), it can be usefuil to disable it.

  • list all network interfaces
# /bin/ls -1 /sys/class/net/
enp0s31f6
lo
  • edit /etc/network/interfaces:
rename enp0s31f6=eth0
auto eth0
iface eth0 inet static
   address 142.90.120.94/19
   gateway 142.90.100.18
  • statically configure systemd-resolved
    • create /etc/systemd/resolved.conf.d/resolved.conf with this contents:
[Resolve]
DNS=142.90.100.19
Domains=triumf.ca
    • systemctl restart systemd-resolved
    • resolvectl
    • systemd-analyze cat-config systemd/resolved.conf
  • disable NetworkManager
systemctl disable NetworkManager
  • reboot

Configure ECC memory

Configure EDAC

  • apt install edac-utils rasdaemon

Setup ubuntu as gateway to private network

See also:

Steps to do

!!! UPDATED 16feb2024 Ubuntu-22.04.03 !!!

  • assign network numbers to the private network, i.e. 192.168.1.x, 192.168.2.x, etc
  • (on the gateway machine, each private network interface has to have a different network number)
  • (each network interface can have multiple networks attached, via VLANs or via eth0:0, eth0:1 constructs)
  • assign IP addresses on the private network, save them in /etc/hosts i.e. "hvps 192.168.1.10"
  • (for simplicity, assign 192.168.1.1 to the gateway machine itself)
  • (IP addresses 192.168.1.0 and 192.168.1.255 are "special", do not use them)
  • setup DNS server (dnsmasq) to serve contents of /etc/hosts via DNS (otherwise, many programs will see inconsistent name to IP address mapping)
  • setup DHCP server (dnsmasq) to give out the IP addresses
  • setup TFTP server (dnsmasq), pxelinux and NFS for diskless booting
  • setup time server (chronyd) to provide common time to all devices
  • setup NAT so machines on private network can access the internet (to get OS updates, etc)
  • setup NIS and NFS so machines on the private network can use common home directories
  • setup rsync backup of machines on the private network

setup hosts

  • edit /etc/hosts
192.168.1.101 dsfe01
... and so forth

setup dns and dhcp

!!! updated 16feb2024 for Ubuntu 22.04.3 !!!

!!! note: stock systemd-resolved remains, is configured to forward queries to dnsmasq, configured to forward queries to TRIUMF DNS !!!

!!! note: per authors of systemd, bare hostnames are not permitted, a DNS domain name must always be used. DNS domain name "dsdaq" is used in this example !!!

  • apt install dnsmasq
  • ensure dnsmasq starts after all interfaces are up (Ubuntu-22)
mkdir /etc/systemd/system/dnsmasq.service.d
echo -e "[Unit]\nAfter=network-online.target\n" > /etc/systemd/system/dnsmasq.service.d/local.conf

setup efi http boot

https://documentation.suse.com/sles/15-SP2/html/SLES-all/cha-deployment-prep-uefi-httpboot.html

setup linux kernel

  • copy the kernel files
cd /boot
rsync -av config* initrd* System.map* vmlinuz* /tftpboot/
  • cd /tftpboot
  • chmod a+r *

setup nfs

  • apt-get install nfs-kernel-server
  • enable NFS over UDP, edit /etc/nfs.conf add "udp=y":
udp=y

systemctl restart nfs-server.service
  • emacs -nw /etc/exports
/nfsroot/dsfe01 dsfe01(rw,no_root_squash,async,no_subtree_check)
  • enable services
systemctl enable nfs-server
systemctl enable nfs-mountd
systemctl enable nfs-idmapd
systemctl restart nfs-server
systemctl restart nfs-mountd
systemctl restart nfs-idmapd
  • after editing /etc/exports, run
exportfs -av

setup userland

!!! ubuntu-18 version !!!

  • zfs create rpool/nfsroot
  • zfs set dedup=verify rpool/nfsroot ### enable deduplication to save disk space because most linux images have mostly identical files
  • clone ubuntu
mkdir /nfsroot/dsfe01
cd /
rsync -avx . /nfsroot/dsfe01
  • edit config files:
  • cd /nfsroot/dsfe01
  • emacs -nw etc/hostname ### change to dsfe01
  • emacs -nw etc/mailname ### change to dsfe01
  • emacs -nw etc/yp.conf ### change daq00.triumf.ca to musr00.triumf.ca
  • emacs -nw etc/defaultdomain ### change to MUSR-NIS
  • cp -pvf ../lxcpet-SL610/etc/ssh/*key* etc/ssh/ ### preserve the ssh keys
  • emacs -nw opt/gonodeinfo/gonodeinfo.conf ### update information
  • emacs -nw root/.ssh/authorized_keys ### update root ssh keys
  • emacs -nw etc/fstab ### add this
192.168.1.1:/nfsroot/dsfe01 / nfs defaults,nolock 0 0
  • emacs -nw etc/chrony/chrony.conf
    • comment-out all "pool" and "server" entries
    • add entry "server 192.168.1.1 iburst"

After dsfe01 is booted:

  • disable services:
systemctl disable apache2
systemctl disable dnsmasq
systemctl disable zfs-import-cache

To setup additional machines, clone dsfe01 instead of cloning the gateway machine

Allow manpages to be viewed

If / is mounted over NFS, man will report a permission error. Fix it with: 

ln -s /etc/apparmor.d/usr.bin.man /etc/apparmor.d/disable/
apparmor_parser -R /etc/apparmor.d/usr.bin.man

setup shared home directory

on the gateway machine

  • define netgroups
  • emacs -nw /etc/netgroup
dsfe (dsfe01,,) (dsfe02,,)
  • emacs -nw /etc/nsswitch.conf ### edit the netgroup line to read:
netgroup: files
  • export the home directories:
  • emacs -nw /etc/exports ### add this:
/zssd/home1 @dsfe(rw,no_root_squash,async,no_subtree_check)
  • exportfs -rc

on the frontend machine

  • mkdir /home
  • emacs -nw /etc/fstab ### add this:
192.168.1.1:/zssd/home1 /home nfs defaults 0 0
  • mount -a

setup NAT

NAT allows machines on the private network to connect to the internet: https://en.wikipedia.org/wiki/Network_address_translation

In these examples:

  • replace "eno1" with name of the outgoing interface (the one connected to the TRIUMF network).
  • replace "enp11s0" with name of the private network interface (192.168.1.x network)
  • emacs -nw /etc/rc.local ### add this:
# /etc/rc.local

# enable NAT

/sbin/iptables -t nat -A POSTROUTING -o eno1 -j MASQUERADE
iptables -L -v

# uncomment following lines if machine has prohibitive FORWARD rules:
#/sbin/iptables -I FORWARD -i eno1 -o enp11s0 -m state --state RELATED,ESTABLISHED -j ACCEPT
#/sbin/iptables -I FORWARD -i enp11s0 -o eno1 -j ACCEPT

ARM cross-compiler

NOTE!!!

THIS IS NOT AN AARCH64 (arm64) CROSSCOMPILER!

NOTE!!!

  • install packages:
apt install libgcc-9-dev-arm64-cross
apt install gcc-arm-linux-gnueabi
apt install gcc-arm-linux-gnueabihf
apt install g++-arm-linux-gnueabihf
apt install g++-arm-linux-gnueabi
  • find out the correct -march setting, on the target machine, run:
root@gdm00:~# g++ -Q --help=target | grep march
  -march=                     		armv8-a

32-bit intel cross-compiler

Ubuntu 22.04: 

apt install libstdc++-11-dev:i386
apt install zlib1g-dev:i386

NOTES:

  • "g++ -m32" does not find libstdc++, please use "g++ -m32 -L/usr/lib/gcc/i686-linux-gnu/11/"
  • to cross-build 32-bit MIDAS, use "make linux32".
  • executables cross-build on Ubuntu-22 do NOT run on 32-bit Debain-11 (GLIBC and GLIBCXX version mismatch)
  • executables cross-build on Ubuntu-22 run on 32-bit Debian-12.
