Hmm, looks good, what's your IP address and that of the gateway?

Bcast is the same as the gateway address showed in the 3rd line when I type "route -n"

That cannot be good...okay, let's try something, enter

Quote:
ifconfig
and post what you get about eth0 here...

When a network is unreachable, that can mean that the two hosts are in a different subnet. You could have (let's say) 192.168.1.250 and the gateway 192.168.0.24, I marked the numbers of interest in red. This difference could make a network unreachable.

Gotcha! And what is the IP address of the gateway?

Oh, by the way, do the same routine with a well-behaved box, you'll see a different IP address...of course, but apart from the last entry, the three first entries should be the same...

Hmm, this means that the IP address of your box should be 129.112.14.X - where X is any number you did not use for your other boxes...try this

Quote:
ifconfig eth0 129.112.14.X netmask 255.255.255.0 bcast 129.112.14.255 up
I tried to supply data that is used in your system, save for the X, you'll need to put something in there yourself, between 1 and 255 inclusive...

Nonono, it should read:

Quote:
ifconfig eth0 129.112.14.X netmask 255.255.14.0 bcast 129.112.14.255 up
where X is any number between 1 and 255, and NOT used already
By the way, can you ask an IP address from the IT manager? Just a thought, since this is a university

same result:
SIOSIFADDR:Invalid argument
bcast: Host name lookup failure

I think the 255.255.255.0 is the network mask, because there is a note on the computer said so.

You're right, but, due to the structure of your IP address, it may need to me 255.255.14.0
