Set connection timeouts?

[Kārlis Repsons]

Hello,
Perhaps you could give some information here or redirect me, because it was 
not clear while reading manuals: how can connection timeout be set for sshd?
Problem is, when some system is hibernated and it resumes, connections are 
dead. Mostly I made a successful workaround, but would be nice to know...
Also, which version of ssh(d) support df on sshfs?

I hope, is not a problem to enlighten me a little!
