This has been bothering me for a long time. When I ssh or sftp into my server via PuTTY or WinSCP, it drops out after 2 minutes, then has to reconnect. PuTTY will just lock up and not let me type... it wont say inactive just pure lockup. WinSCP will say "host not communicating" then I press reconnect and it reconnects...

This happens within 3-5 minutes! It's driving me mad!

On my other PC, connecting to the same server same version of both programs it will stay connected for 24 hours! I even reformatted my PC and still same issue, do you have any ideas to solve this?

This means your server has some connection timeout (try a look at its sshd_config file or equivalent).

You can try to play with the "keep alive" options in PuTTY or WinSCP. Here are my options for some similar case connection:

PuTTY:

WinSCP

Open the following dialog by going to your site, clicking Edit and Advanced and going to Connection page:

  • Those settings seem to keep putty up. Now for winscp. – Josip Gòdly Zirdum Feb 13 '12 at 22:21
  • Same logic: connection -> keepalive settings (I edited my answer and add an example, through not tested). – Ouki Feb 13 '12 at 22:36
  • I was trying to find the settings lol. I was going through preferences I guess I had to exit it and then I could access the connections. Thanks :) – Josip Gòdly Zirdum Feb 14 '12 at 2:52
  • I cannot find this on WinScp 5.9.3. – zwcloud May 6 '18 at 10:48
