I don't understand why admins don't answer correctly to the questions at first. This is my conversation (well, a little exaggerated) by mail with one of those:

Me - Hi! In the private networks of the Computer Science Department we can access all department network, but we can't ssh to outside the network.

Admin - Yes. That's true. You must use a proxy.

(Erm, a proxy for ssh?)

Me - Well, but how can I use ssh through the proxy?

Admin - You can't.

(Good. At least I know what a proxy and ssh are! I have plenty of patience but today wasn't one of those days...)

Me - Ok. We'll manage to create a ssh tunnel through another machine. No problem. But, meanwhile, why can't we do it?

Admin - Basically, three reasons: 1) a lot of worm infected computers were attacking machines; 2) teachers and researchers don't have much time to apply patches to their machines and 3) this way the machines are hidden and can't be accessed from outside.

(Hmms... nice reasons. We want access from inside to outside, so 2 and 3 are useless. For 1, we are all sorry for Microsoft.)

Me - Ok, we all know NAT. I think that solves 2 and 3. Also, the first will continue to happen. We know there are a lot of Windows machines on the external network.

Admin - The problem is that the network hardware does not support NAT. If you get me an old machine we can install it with Linux to work as firewall and NAT.

(Ho!!! Now you got me! I am very ignorant about networks. I don't know if the excuse is good... but... it could be told as first answer to my first question, or is just me?)

Me - Ok...

I think the society misses a lot of interesting nobel prizes. See for example, the invention of the bed. The researcher who did it should be congratulated with, at least, the Peace Nobel Prize.

This was the movie of the weekend (imdb). Finally the TV shows some interesting movie. It is a comedy, you can classify it as a stupid comedy, but it is funny. It includes a stupid guy and a nice girl. What else do you need?

I'll vote 6/10. If you like to laugh, and you don't mind some stupidity, see it!
