Instructions for setting up a DAQ test computer

Elliott Wolin, 20-Aug-2008

Instructions for configuring a Hall D DAQ computer for stand-alone operation, after installing RHEL5 from JLab CD using standard halld passwords. Instructions below assume host name moe.jlab.org and VxWorks processor pmt1.jlab.org, and that daq system is on a private ethernet (eth1) and not on eth0.

From the root account:

• create halld group gid=267

• create halld account id=500 with standard password, set halld as primary group

• have computer center mount /group/halld and /group/da, or at least allow the computer to mount them. If the latter:

     $ mkdir /group
     $ chmod a+rwx /group
     $ ln -s /misc/da /group/da
     $ ln -s /misc/halld /group/halld

• Edit /etc/auto.misc and add:

     da              -rw             jlabgrp:/vol/vol1/da
     halld           -rw             jlabgrp:/vol/vol1/halld

• and finally:

     $ mount -a

• yum install:
  • minicom
  • xinetd
  • ant
  • rsh-server
  • some-java-version (use yum search java)

• enable rsh in /etc/xinetd.d/rsh:

     socket_type             = stream
     wait                    = no
     user                    = root
     log_on_success          += USERID
     log_on_failure          += USERID
     server                  = /usr/sbin/in.rshd
     disable                 = no

- confiture autostart of xinetd/rsh and ncsd:

     /sbin/chkconfig xinetd on
     /sbin/chkconfig nscd   on

- start xinetd and nscd:

     /sbin/service xinetd start
     /sbin/service nscd   start

(or /etc/init.d/xinetd start, etc)

- edit /etc/hosts:

     127.0.0.1       moe localhost localhost.localdomain moe.jlab.org
     ::1             localhost.localdomain   localhost
     192.168.1.2     pmt1    

- configure eth1 for static routing, IP address 192.168.1.1 using gui

- edit network files:

     /etc/sysconfig/network-scripts/ifcfg-eth0

PEERDNS=yes

     /etc/sysconfig/network-scripts/ifcfg-eth1

PEERDNS=no

     /etc/sysconfig/network

turned IPv6 off set hostname to moe (was localhost)

- activate eth1 (can also use gui):

     /sbin/ifup eth1

- edit /etc/sudoers and add:

     halld   ALL=(ALL)       ALL

- fix ttyS0 permisions for minicom. May be needed after every reboot:

     chmod a+rw /dev/ttyS0

 or from halld account:

     sudo chmod a+rw /dev/ttyS0

These can be done from halld account:

- copy files from /group/da/ejw/daq-config into halld home dir:

     .complete.tcsh
     .emacs 
     .cshrc
     .alias  
     .login 

- create /home/halld/.xemacs and copy from /group/da/ejw/daq-config:

     init.el 
     custom.el

- create /home/halld/.rhosts:

     192.168.1.2
     pmt1.jlab.org

- set .rhost permissions:

     chmod u=rw .rhosts

- reboot if something is not working properly. Contact computer

 center if reboot doesn't help.
