Just installed a new system and was having ssh connections timeout. Then I remembered talking about this same issue last year on IRC. The anecdote is amusing so I figured I would post the logs:
[Mon April 22 2013] * abadger1999 wishes he knew why his ssh connections to infra keep on hanging.
[Mon April 22 2013] <abadger1999> it’s a timeout of some sort… I just don’t know what.
[Mon April 22 2013] <skvidal> abadger1999: did you reinstall recently?
[Mon April 22 2013] <abadger1999> skvidal: nope
[Mon April 22 2013] <abadger1999> skvidal: would that help?
[Mon April 22 2013] * abadger1999 still on f17
[Mon April 22 2013] <skvidal> I have found I often need to set
[Mon April 22 2013] <skvidal> net.ipv4.tcp_keepalive_time = 300
[Mon April 22 2013] <skvidal> in /etc/sysctl.conf
[Mon April 22 2013] <skvidal> to not get timeouts
[Mon April 22 2013] <abadger1999> Thanks. I’ll try that .[…]
[Wed April 24 2013] <abadger1999> skvidal: btw, your sysctl recipe seems to have fixd my ssh timeout issues. Thanks!
[Wed April 24 2013] <skvidal> abadger1999: 🙂
[Wed April 24 2013] <skvidal> abadger1999: last time it happened to me I had to google for the solution
[Wed April 24 2013] <skvidal> abadger1999: and I found a post from myself from 5yrs earlier
[Wed April 24 2013]Â <skvidal> abadger1999: _that_ is kinda freaky
[Wed April 24 2013] <pingou> isn’t that what blog are for? 🙂
[Wed April 24 2013] <dwa> nice
[Wed April 24 2013] <abadger1999> Cool 🙂
[Wed April 24 2013]Â <skvidal> “wow, this dude knew what was going on…. but he sure writes like he’s an ass”
[Wed April 24 2013]Â <skvidal> “oh….. wait”

Seth, you were more of a teddy bear than an ass.
