[NCUC E-team] server security

[Tapani Tarvainen]

All,

I've tightened the security of our server due to
persistent attacks.

I may have overdone it and blocked some necessary traffic,
so if anyone notices something doesn't work anymore,
please let me know ASAP.

And those of you who have shell access to the server:
please let me know which IP addresses you're coming from
so I can punch holes in the firewall for you.

Thank you.
