Process SSH Service Health

Microsoft.Solaris.10.Process.Ssh.Monitor (UnitMonitor)

Solaris 10 Process SSH Monitor

Knowledge Base article:

Summary

This process monitor watches for the SSHD process to be running. SSHD is the daemon for ssh. It replaces rlogin and rsh, and provides secure encrypted communication between two untrusted hosts over an insecure network. There should be at least one process running at all times.

Causes

A failure indicates that the ssh service on the system is down.

Resolutions

Check the service by running ps -ef | grep sshd or by viewing the diagnostic in the Operations Manager Console. If it is down, try to login via telnet or rlogin. If these are disabled, you can login to the console. You can start the service by running the command "svcadm enable ssh" or by clicking the recovery link in the Operations Manager Console.

For root cause analysis, first check the system logfile (/var/adm/messages), and view any related entries at the time of failure. You may also check the system for any process core files. Use '/usr/bin/pstack [corefile]' to print a stack trace which will assist in troubleshooting the cause of failure.
