RHEL5 Base Linux Image Creation

["Hartl, Gerhard L." <GH...@odu.edu>]

I'm attempting to create a base Linux image and keep getting stuck in the same spot.  The image is capturing properly, but when Linux is going through post load, something breaks ssh.  I don't understand why "/etc/init.d/ext_sshd stop" would halt ssh on the private interface?!?

I ran into this same problem.  The issue is the RHEL5 init script for sshd;
when asked to "stop", it runs killproc on sshd (the command string).
This kills both the private and public SSH daemons.

I modified the RHEL script to instead call 'killproc -p' on the PID, not the
command name:

> diff /tmp/ext_sshd /etc/init.d/sshd 
30,31c30
< PID_FILE=/var/run/ext_sshd.pid
< OPTIONS='-f /etc/ssh/external_sshd_config'
