If you haven't already done so (can't see it in the threads), open up your ssh_config file (in /etc/ssh) and add the following line.<br><br> ServerAliveInterval 120<br><br></span><span id="b9f61e0d-e5d1-4d79-82e6-5bbca407d0fc">Or 60 or something like that. </span><span id="b9f61e0d-e5d1-4d79-82e6-5bbca407d0fc">Similarly, on the server side, you can edit the sshd_config file and add the following.<br><br> ClientAliveInterval 120<br><br>The idea here is that the client, or server, will send a message over the SSH connection every 120 seconds (or 60 seconds or whatever) thereby making sure the connection doesn't time out. For the server side, you obviously need to restart sshd for the changes to take effect.<br><br>Take care out there.<br><br></span><span id="b9f61e0d-e5d1-4d79-82e6-5bbca407d0fc"><span name="x"></span>-- <br>Marcel Gagné<br>Salmar Consulting Inc. : 519-772-7742<br>55 King Street West, 7th Floor<br>Kitchener, Ontario, N2G 4W1<br>Note: This massagee wos nat speel or gramer-checkered.<span name="x"></span><br></span><br><hr id="zwchr"><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px; color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><b>From: </b>kwlug-disc-request@kwlug.org<br><b>To: </b>kwlug-disc@kwlug.org<br><b>Sent: </b>Thursday, June 30, 2011 12:00:01 PM<br><b>Subject: </b>kwlug-disc Digest, Vol 31, Issue 39<br><br><br>Today's Topics:<br><br> 1.
