You may find that after a period of inactivity your connection to a unix machine (solaris or linux) disconnects automatically. Typically this time might be something like one hour.
There are 3 possible causes for such inactivity timeouts:
In the first case you should receive single word message "auto-logout" immediately before the logout occurs.
In both the second and third cases you may receive a message similar to:
the connection may also just seem to hang, or the connection will return you to your client machines prompt.
The solution to the first case (the automatic logout timeout for the login shell) is to unset the autologout shell variable. To do this:
If you are connecting from a MacOS, Linux, or other unix based machine the solution to both the second and third cases (ssh timeout or tcp inactivity) is the same:
It may be necessary to adjust the value of ServerAliveInterval to a lower number, however too low a number may actually cause additional disconnects if the the connection is only temporarily down. Do not set this number to a value less than 60 (one minute).
If you experience the SSH or TCP timeout problem from a Windows SSH client please contact us as there doesn't appear to be a way to alter these settings in the Windows client and further research will be required.
