I've installed OpenSSH on an IBM RS/6000 7025 F50 server that's
running AIX 6.2. I naturally want the sshd deamon to start at boot
time. I'm new to AIX, so don't know if I'm starting trying to start
this correctly or not.

I have put the following file

# ls -l /etc/rc.d/rc3.d
total 8
-rwxr-xr-x 1 root system 183 01 Aug 19:29 S90sshd

which has the contents below.

#! /bin/ksh

case "$1" in
start )
/usr/local/sbin/sshd
;;
stop )
#next line is just temporary
ls > /dev/null
;;
* )
echo "Usage: $0 (start | stop)"
exit 1
esac



but sshd is not starting. If I start it manually by logging in as root
and running /usr/local/sbin/sshd, it works fine.

Any suggestions?

I've found the answer to this myself. I wrongfully assumed run level 3
was multi-user modes as in Solaris, but I see this is not the case.
Seems like the system never went to run level 3, so the script did not
execute. Putting it in /etc/rc.d/rc2/d solved it.

AIX 4.3.3 has the SYSV startup too.
And for those coming from another *NIX, the SRC is one of AIX' secrets.

Think it's a matter of taste calling the SRC from /etc/rc.d/rc2.d/S* or
/etc/inittab.
On AIX 4.3.3 the /etc/rc.d/rc2.d directory is empty by default.
And if the inittab calls rc scripts, the rc scripts call the SRC, almost for
all those I have looked at.

IMHO the SYSV startup is more flexible and as easy as the BSD startup, but
what I really don't like is a confusing mixup of both.

If I can manage to prevent the Apache supervisor process from detaching, I
will change startup of the Apache to SRC. My Apache (1.3.27 built from
source with GCC 3.2.3) ignores the flag for not detaching. So the SRC cannot
shutdown cleanly and after a reboot there is an invalid PID-file. Arrgghhh.
Only a stylistic question.
