Network configuration (TRIUMF)
DEAP DAQ machines are on the private network 192.168.1.x (netmask 255.255.255.0)
Gateway to TRIUMF network is 1U machine deap06.triumf.ca connected to the LADD-NIS cluster (deap account on ladd00).
Gateway services running on the gateway:
- DHCP server for the 192.168.1.x network (/etc/hosts, /etc/dhcp/dhcpd.conf)
- apache SSL/https proxy for MIDAS status page, ELOG, ganglia and nodeinfo (/etc/httpd/conf.d/ssl.conf)
- NAT proxy from private network to the TRIUMF network (/etc/rc.local). Makes the internet accessible from deapNN machines.
Network configuration (DEAP)
The DEAP DAQ cluster is configured for standalone running with or without an internet connection.
(NB: Some internet functions are required: access to NTP for time synchronization and access to Linux package repositories to install packages, etc)
Usernames, passwords and hostnames are distributed using NIS:
- domain name: DEAP-NIS
- deap00 is the master server
- there are no secondary servers
