The hotel in Thailand that I’m currently staying in is for some inexplicable reason blocking SSH, randomly. 6 hours ago it was working fine, but now when I need to do some work it’s decided to block me. At least that’s what I think is happening as all other requests work fine. I think it’s using some deep packet inspection too, as moving to another port also doesn’t work.SSH Over TorBrowser

My home Ubuntu Jaunty installation often takes a good 40-60 seconds to connect to using SSH, none of the other servers I maintain have this same problem, they’re pretty much instantaneous, and today, on a Friday evening at 1am this irked me enough to fix it!
The first step is of course to make the SSH connection with debug output on.
