[K12OSN] terminal was working, now stalls when loading kernel

[Petre Scheie]

I did all those things--no joy.  However, I just shutdown iptables and the 
client login popped right up (I'm off-site, but after I shut iptables down, the 
user went back to his workstation and said the login screen was there).  So, 
I'll have to twiddle with iptable settings I guess.
