openssh unix dev - Mar 2001 - SIGHUP/av[0] restart failure

Hello,

OpenSSH 2.5.1p1 running under AIX 4.3.3ML06.  When I send a HUP 
signal to the parent sshd, that parent process dies, it's children 
get "adopted" by init, and the following message is put in the error 
log ...

Mar 13 12:01:48 whippet sshd[31644]: Received SIGHUP; restarting.
Mar 13 12:01:48 whippet sshd[31644]: RESTART FAILED: av[0]='sshd', 
error: No such file or directory.

The sshd program is not named anything unusual, and is located in 
/usr/local/sbin.

I searched this list (and other places),  and found some info related 
to the above, but not anything that I'd call a solution or a 
resolution.

Help?   Thanks!

man sshd:

     sshd rereads its configuration file when it receives a hangup signal,
     SIGHUP, by executing itself with the name it was started as, ie.
     /usr/sbin/sshd.

That is what I understand, myself. It tries to respawn itself on SIGHUP,
and if you don't have the full path specified it may not be able to find the
executable.

Try it and see. ;)

P.S. Try Douglas Manton's suggestion for spawning it from SRC. It's
another
one of those things done right in AIX, IMHO. (Too bad AIX has other funky
things making it a poor choice for my needs...)

ok, so in my rc.sshd startup script, when I get to the part where I 
actually start sshd, I need to specify its full path?

I've got ...

PATH=/usr/local/sbin: ...

and later ...

sshd

but you are saying that I need to have it start as ...

/usr/local/sbin/sshd

right?

Thanks!
