SSH not running and will not restart

[NigelP]

I am suppose to have SSH running on an rp7400 server yet when I do a ps -ef and grep sshd it returns only the grep.  I then run /sbin/init.d/secsh start  it displays HP-UX Secure Shell started  run ps -ef and grep sshd it returns only the grep again.

any ideas would be much appriciated

Anything in syslog or dmesg output that would give you a hint?  Check /etc/rc.log to make sure it came up initially, too.

You should also check the /etc/rc.config.d/sshd file.  Confirm that SSHD_START=1 in /etc/rc.config.d/sshd.  If it is set to 0, the secsh init script will not start sshd.

Using "sh -x" when you run the init script should give you a bit more detail to help you troubleshoot.

sh -x /sbin/init.d/secsh start

Shalom,

Most of the time when this happens to me (and it does) the sshd configuration file is the culprit.

If that is not the case a set -x near the top of the /sbin/init.d/secsh script will do the diagnosis.

If you reach the diagnosis stage post.

swlist -l product | egrep -i "secure|shell"

Post the swlist ouptut to see if secure shell is properly installed.

Thanks Guys.

Looking at the syslog, when I have attempted to start ssh it has didplayed Error: Bind to port 22 on 0.0.0.0 failed: Address already in use.  fatal: cannot bind any address.

I then ran

aodxap03:syslog(222)# sh -x /sbin/init.d/secsh start

+ PATH=/usr/sbin:/usr/bin:/sbin:/usr/local/sbin:/usr/local/bin

+ export PATH

+ WHAT=HP-UX Secure Shell

+ WHAT_PATH=/opt/ssh/sbin/sshd

+ WHAT_PID=/var/run/sshd.pid

+ WHAT_CONFIG=/etc/rc.config.d/sshd

+ rval=0

+ [ -f /etc/rc.config.d/sshd ]

+ . /etc/rc.config.d/sshd

+ SSHD_START=1

+ SSHD_ARGS=

+ ps -ef

+ grep /opt/ssh/sbin/sshd

+ grep -v grep

+ 1> /dev/null

+ NOT_RUNNING=1

+ [ 1 -eq 1 -a -x /opt/ssh/sbin/sshd -a 1 -eq 1 ]

+ /opt/ssh/sbin/sshd

+ echo HP-UX Secure Shell started

HP-UX Secure Shell started

+ set_return

+ exit 0

followed by

aodxap03:syslog(223)# swlist -l product | egrep -i "secure|shel"

  Keyshell              B.11.11        Keyshell

  Secure_Shell          A.04.20.004    HP-UX Secure Shell

aodxap03:syslog(224)#

From that output it looks like it might have started this time - at least I don't see any errors.  What does ps -ef  |grep ssh return?

[NigelP]

| grep ssh just returns the grep

[Patrick Wallek]

Do you have lsof installed on the system?  If so, run 'lsof -i tcp:22' to see what process is accessing port 22.

[Pete Randall]

That, by the way, is a pretty old version of Secure Shell.  You might want to consider downloading the current offering (5.80.01):  https://h20392.www2.hp.com/portal/swdepot/try.do?productNumber=T1471AA&lang=EN&cc=EN&hpappid=PDAPI_SWD

[NigelP]

yes I know it's an old version.  if it ain't broke don't fix it! but it may be time to look at upgrading ssh.
