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.
Instructions also assume that the main (JLab) network connection is on eth0, and the daq system is on a private network eth1.
Elliott Wolin, 20-Aug-2008
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:
$ /etc/init.d/autofs restart
- yum install:
- minicom
- xinetd
- ant
- rsh-server
- some-java-version (use yum search java) (e.g. java-1.6.0-ibm-devel.i386)
- scons.noarch
Also interesting for debugging network traffic are tcpdump, wireshark, and wireshark-gnome.
- enable rsh in /etc/xinetd.d/rsh on the local private network only:
socket_type = stream wait = no user = root log_on_success += USERID log_on_failure += USERID server = /usr/sbin/in.rshd disable = no only_from = 192.168.0.0/16 bind = 192.168.1.1
- 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
- note that cfengine may disable rsh, need to talk to Sherman White to get exemption for host computer
- configure eth0 for DHCP on the JLab network
- 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 ONBOOT=yes
- /etc/sysconfig/network-scripts/ifcfg-eth1
PEERDNS=no ONBOOT=YES
- /etc/sysconfig/network
- turn IPv6 off
- set hostname to moe
- activate eth0 and eth1 (can also use gui):
/sbin/ifup eth0 /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.
- setting vxWorks boot parameters:
[VxWorks Boot]: p
boot device : scsi=2,0 processor number : 0 host name : mizar file name : /sd0/boot/vx2700_sd0 inet on ethernet (e) : 129.57.14.20:fffffc00 host inet (h) : 129.57.14.33 gateway inet (g) : 129.57.12.1 user (u) : abbottd flags (f) : 0x20 target name (tn) : davw10 startup script (s) : /sd0/drew/pem/pemv7.boot other (o) : dc
host name - Name of the Unix host e - IP address of the board:subnet mask (should be in /etc/hosts on unix as well) h - Unix host IP address g - IP gateway (this is optional - it can be cleared) u - username on unix host tn - name of VME board (should be in /etc/hosts on unix) o - device name for the network interface (dc)
- nfs mounts on vxWorks
- nfsMount("host","file_system")
- minicom settings
- /dev/ttyS0
- 9600 8N1
- Future possibilities
- snapshot using rsync
