Unhappy LAN problem


Hi,
I'm running a mandrake 9.1 on a dell laptop computer with 3com ethernet adapter. I was connecting to the internet through a university lan and it used to work. I had to change my IP and I cannot connect any more. What do you think could be wrong?
Thanks

Do you need to setup your ethernet for DHCP or with a static IP ?

You can use the internet connection wizard (DrakNet)
or edit the following file manually.
/etc/sysconfig/network-scripts/ifcfg-eth0

I'm using a static ip
I checked the ips from the drake, they seem to be correct any other ideas

Can you ping other IP addresses on the internet ?
If you can ping an IP (66.218.71.198) and not the domain name (yahoo.com), then your DNS may be mis-configured.
Take a look at the /etc/resolv.conf to make sure you have the correct DNS.

Also, make sure your network service is active.
service network status

Changed your IP, is this still part of the Uni LAN you are connected to?

When you changed you're IP was this assigned to you or did you pick one yourself, what was the IP , subnet mask and gateway (if ya remember) compared to what you're using now?

If you're still part of the Uni Lan wondering if you're conflicting with an other IP on it


oh and ping localhost just for good measure.

thanks Looking_Lost.
I changed my IP from the dormatories internet office cos I changed my room. That is to say my new ip is totally legal. I can ping myself. Also I can connect to the internet and everything was normal under windows. I'll contact the office on monday. until then please reply if you've got any ideas. I'll write the conclusion here.
Thank you

Well that makes it a different story then

do as pppuru do

and maybe check you've put in exactly the same static settings as you did with windows (you've probably done it a hundred times though probably) easy to make a mistake with the subnet mask and gateway
