Or you get a long cross-over cable, and or long cable +
switch......Depend how far your computers are physically seperated.

Out of interest, what happens if you nmap your buddies IP and your own
from his box?

I had a buddy in my lan with whom I shared files and such. But

recently our campus network management decided to give our my dorm

building another external ip, and put a firewall( I think) between

us. So now instead of both of us having the same 141.85.0.75 I now

have 141.85.0.76. So my question is, being a n00b and all, what can

I use in order to restore the direct connection? I asked my only

physical present network admin but apparently his only role is

pugin computers in switches and give us an ip so he doesn't know

nothing. I did a nmap on the gateway but I've only found 53/tcp

open. I wouldn't wanna revert to skype or other 3rd party computers

since, I guess, it will segnificantlly lower our transfer speeds,

requier bothe our presence...etc. So what way should I be heading

here? Any advice is welcome!Thanks!

    

If only 53 is open, you are pretty much out of luck except for two 

possible solutions:



1. The social solution

You grab a huge bag of gummy bears, carry them to your real network 

administrator and ask him to poke a hole for you and your buddy into 

the firewalls.



2. The technical solution

You get a box completely outside your compus's network into which both 

of you can ssh.
