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 using gui (if remote can get gui via: $ system-config-users)


  • create halld account id=500 with standard password and halld as primary group using gui


  • 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
  • enable rlogin in /etc/xinetd.d/rlogin:  ???


  • configure 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/init.d/nscd   start


  • 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 192.168.1.1, netMask 255.255.255.0 using gui (if remote can get gui via: $ system-config-network)


Edit network files:

  • /etc/sysconfig/network-scripts/ifcfg-eth0
     PEERDNS=yes
  • /etc/sysconfig/network-scripts/ifcfg-eth1
     PEERDNS=no
  • /etc/sysconfig/network
    • turn IPv6 off
    • set hostname to moe


  • 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


From the halld account:


  • copy files from /group/da/ejw/daq-config into halld home dir:
    • .complete.tcsh
    • .emacs
    • .cshrc
    • .alias
    • .login


  • create directory /home/halld/.xemacs and copy in 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
     chmod go-rw .rhosts


  • reboot if something is not working properly. Contact computer center if reboot doesn't help.


  • Future possibilities
    • snapshot using rsync
