[YLUG] ssh

[Nicholas Thomas]

Does nobody learn basic networking these days? :p

I caught your access, by the way... looks like this:

tcp        0      0 81.187.208.246:443      194.81.1.4:55425        
ESTABLISHED

(interestingly, leeds.ac.uk owns that second IP).

172.16.0.0 is a private subnet, which is to say, it's like 10.0.0.0 - 
private routing only. As for how to fix it... not a clue, sorry. Could 
be that your socket is just patched into the wrong switch somewhere, or 
something. Although, given the /highly/ computer-savvy nature of most 
York students, I'm sure such a mistake would be spotted and corrected 
instantly... right? ;)
