QUESTION: How to avoid ssh tunnel timing out?

[lucharo]

Hello, I would like to know a couple of things:

• What is the default timeout? How long does it take an ssh connection to stop using this package?
• how can it be changed/extended?

I've read a few options in stack overflow and the pull request #156 but I am not confident SSH_TIMEOUT is what I am looking for, could you clarify my doubts?

There are some cases:

1. ssh client-side timeouts
2. ssh server-side timeouts
3. NAT timeout or some network proxy host timeouts

Currently, we don't have timeout options for the case1. We can add it as a new feature in future releases.

The case2 is configured on the server-side and depends on the ssh server.

You can prevent case 3 by using set_keepalive options. But there is no 100% guarantee that your network/router rules don't break long TCP connections.

We also have SSH_TIMEOUT as your say, but it's for socket.settimeout (docs) and yes, it's not what are you looking for.

Thanks for the answer @pahaz. I think that along with the set_keepalive option in paramiko and this I am able to sustain a longer SSH session!

Probably, it’s better to set it by default in a future major release.
