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.
