My problem is that when I try to add gw it sais NETWORK IS UNREACHABLE! I have an external IP : 80.96.157.xxx Mask 255.255.255.240 I can't make it work! I can't connect to the internet. And another thing: how do i calculate the Bcast Address?? ( any help please? I have RH 8

Hi xavier23,

Could you provide us with some more information about your internet connection, do you connect through a dsl router i.e. ?

In such a case you will need to assign to your pc an IP address in the same subnet with the IP address of the internal interface of the router and set it as your default gateway, [code:1]route add default gw x.x.x.x[/code:1].

As for the broadcast address, it will be the last IP of your subnet. You can read the excelent tutorials here about subneting. Also check a practical calculator online service, here

I'll have to ask my admin -- on how do i connect. The IP that he gave me(80.96.234.xxx with 255.255.255.240) is the one i'm using with winXP. He doesn't know linux so he will not be much help. Thanks for the nice answere.

Sorry for posting so late, but i waited to get Mandrakelinux 10.0 from a friend. I installed it and it sais the same thing. I connect through a router -- linux crux. if u want more details please be more specific cause I don't know what u need to know

Thanks again for answering, and one more time sorry for the delay

Your gateway should be on the same subnet with your address. If you ask your administrator, he should provide you with a static IP address on the internal network that you should use, a subnet mask and the local gateway. If these information are valid, you should not see that message. Alternativelly, your administrator may tell you to get these information from DCHP, in which case you should set up a DCHP client in your pc which is simple.

Hey, I got it working like this :

[code:1]
route add -host 80.96.xxx.xxx dev eth0
route add default gw 80.96.xxx.xxx
[/code:1]
where 80.96.xxx.xxx --> is the gw

But i have another question : How do I make the eth0 interface to start automaticaly at startup? I want to do it from command line .
