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
- if needed, update git/scripts repository from ladd00 to daq00:
- git remote -v ### if it says daq00, we are good
- git remote set-url origin https://daq00.triumf.ca/~olchansk/git/scripts.git
- git pull ### check that it works
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)

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".

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

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 (U-24)
Ubuntu LTS 24 installed on ZFS has rpool/USERDATA/home_xxx mounted on /home, has to be moved or autofs /home will not work.
zfs list | grep USERDATA | grep home | cut -f1 -d" " zfs set -u mountpoint=/home1 `zfs list | grep USERDATA | grep home | cut -f1 -d" "`
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.

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

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

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

- 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
- try accessing MIDAS https://daq14.triumf.ca/ (make sure mhttpd is running)
- if it's not working, check odb setting FIXME!
- try accessing ELog https://daq14.triumf.ca/elog/ (make sure elogd is running)
- if it's not working, check elogd.cfg file and make sure
SSL = 0
NOTE: if certbot fails with errors about 'module' object has no attribute 'pyopenssl', try this: pip install requests==2.6.0

From https://jupyter.org/install apt install python3-pip pip install jupyterlab pip install notebook ~/.local/bin/jupyter notebook watch the http://localhost:8888 URL that it printed say "no" to offer to start firefox (it will not work!) URL is: http://localhost:8888/tree?token=xxx 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" jupyter page should open with the list of files in the trinat home directory congratulate Brian with full success
Install ZFS quota report
If there are any ZFS volumes, install script to report disk and quota usage

If httpd is configured to redirect "/" to MIDAS mhttpd:
- add following to /etc/apache2/sites-enabled/xxx-ssl.conf in front of "ProxyPass / ..."
- run "systemctl reload apache2"
## do not proxy zfs quota report directory ProxyPass /zfsquotareport/ !

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 "echo 1 > /proc/sys/kernel/core_uses_pid" >> /etc/rc.local
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
Disable Ubuntu Pro nag
best I can tell, impossible at this time.
do not do this

If "apt upgrade" requests Ubuntu Pro or esm-apps, disable the nag:
/bin/rm /etc/apt/apt.conf.d/20apt-esm-hook.conf
do not do this
!!! likely same as above, breaks automatic updates !!!
- comment out /etc/apt/apt.conf.d/20apt-esm-hook.conf
do not do this
!!! removes too many packages !!!
apt remove ubuntu-pro-client

- apt-get update # update package list
- apt-get dist-upgrade # install updated packages and update "kept back" packages
- apt-get autoremove # remove packages that apt thinks should be removed

- manual removal of old snapshots
zsysctl show zsysctl state remove xy69ye -s zsysctl state remove xy69ye zsysctl state remove xy69ye -u wheel
- apt remove zsys
NOTE: old zsys snapshots must be cleaned manually, "zsysctl state remove xxx --system" is broken and does not remove user data snapshots
- manages system snapshots
- documentation: https://github.com/ubuntu/zsys
- documentation: (go to next article via link "newer" at the bottom) https://didrocks.fr/2020/05/21/zfs-focus-on-ubuntu-20.04-lts-whats-new/
- ubuntu 20.04 bug, too many snapshots cause /boot to become full and updates fail. https://github.com/ubuntu/zsys/issues/155
- solution: use custom /etc/zsys.conf, limit number of snapshots to 10, see trinatdaq:/etc/zsys.conf
- zsys commands:
update-grub # list of all snapshots, errors if some snapshots are broken zsysctl state remove lnc0k7 --system # remove snapshot xemacs -nw /etc/zsys.conf; zsysctl service reload; zsysctl service gc # cause gc to run with new settings in zsys.conf zfs list -r -t snapshot -o name,used,referenced,creation bpool/BOOT # list snapshots zsysctl show # show snapshots

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

Setup ubuntu as gateway to private network
See also:

- 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
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
- edit /etc/dnsmasq.conf

- #mkdir /tftpboot ### per tftp-root (if no ZFS)
- zfs create -o mountpoint=/tftpboot rpool/tftpboot ### (if root is ZFS)
- create resolved-dsdaq.conf with main IP address of dnsmasq
[Resolve] DNS=192.168.0.248 Domains=dsdaq triumf.ca
- mkdir -p /etc/systemd/resolved.conf.d/
- /bin/rm -f /etc/systemd/resolved.conf.d/*.conf
- cp resolved-dsdaq.conf /etc/systemd/resolved.conf.d/
- systemctl stop systemd-resolved.service
- systemctl disable systemd-resolved.service
- systemctl enable dnsmasq
- systemctl restart dnsmasq
- try to "ping" or "host" some names from /etc/hosts, it should work
- try to ping daq00, daq00.triumf.ca, all should work
- resolved-dsdaq.conf goes into /etc/systemd/resolved.conf.d/ of all machines on the private network
- if not using systemd-resolved, edit /etc/resolv.conf
setup chronyd
- enable ntp server:
- disable systemd-timesyncd, configure and enable chronyd per instructions above
- create dsdaq.conf
# chrony config for dsdaq server #allow 192.168.0.0 #allow 192.168.1.0 #allow 192.168.2.0 allow all # end
- cp dsdaq.conf /etc/chrony/conf.d/
- systemctl restart chronyd
- chronyc tracking ### wait until time is synchronized (a few seconds)
- create dsdaq.sources # use hostname or IP address of chronyd server
# Put this file in /etc/chrony/sources.d # systemctl restart chrony # chronyc sources # chronyc tracking server dsdaqgw iburst prefer # end
- dsdaq.sources goes to /etc/chrony/sources.d of all machines on the private network

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
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 #iptables -L -v iptables -L -v sysctl -w net.ipv4.ip_forward=1 #sysctl -a | grep forward sh /etc/firewall-rfc1918.sh # end
