Setting up RedHat 9 for the TCS3
Date: 2003/06

0. Used the slackware CDROM & fdisk to make the partition I wanted:
   /dev/hda1  swap
   /dev/hda2  /        # For RH9 installation.
   /dev/hda3  /r1
   /dev/hda5  /r2
   /dev/hda6  /r3

1. Install the RetHat 9

2. Misc setup/fixed:
   /etc/passwd - make accounts.
   /etc/resolv.conf - fix. Add domain
   /etc/ntp.conf - fix. Setup to slave of duke. For T1 use irtfgps1.
   /etc/fstab - fix. Use device name rather that labels.

3. Updates:
    Setup update using apt-get utility.
    Install synaptic
    Install latest kernel: 2.4.20-18.9 (w/ source)

4. Needed to add POXIS messages queues for 2.4.20 kernel
   This require patch the kernel sources and recompiling.
   See /home/tcs3/src/stuff/mqueues for message queue patch
   for instructions.

   4.1 Apply mqueue patch. Then recompile new kernel.

   # cd /duke/home/projects/tcs3/src/stuff/mqueues/mqueues-3.40/
   # patch -p1 -d /usr/src/linux-2.4 < mqueue-2.4.20.patch
    <needed to change wq_add() in ipc/mqueue.c. task->nice
     changed to task->static_prio. RedHat doesn't used vanalla
     2.4.20 kernel, but this seem fix makes the patch work
     with 2.4.20-18.9 source>

   4.2 Compile and run new kernel.

   make clean
   make mrproper
   make oldconfig -> to generate a config based on the running kernel
   make deps
   make bzImage
   make modules
   make modules_install
   make install

   4.3 Installed user portion of mqueue per INSTALL.

5. Other setup

   5.1 NIS 

   Configure NIS so that the host and netgroup table is used by the TCS3. 
   No other NIS+ table should be used.
     check /etc: yp.conf, nsswitch.conf, hosts

     authconfig is the configuration tool.

   5.2 Mounting 

   /duke should be mounted from duke://aux2. /home/tcs3 should link to /duke/home/project/tcs3.
   /irtf.backup should be declared.
