hi,
i have win2K n mandrake 10 installed on my system. n also have Realtek RTL8139/810x Family Fast Ethernet NIC. my lan operator provided me with :

1> ip address : 10.16.11.8
2> default gateway : 10.16.10.3
3> DNS : 10.16.0.2
4> subnet mask : 255.255.255.0
5> domain (but he said its of no use if u r using win2k) : manage

i can use net frm win2k (without domain settings )without any probs. but in linux m getting "network is unreachable" error. i run the following commands:

$ifconfig

while booting my eth0 is getting up......
does anyone know how to solve this prob? i m really confused?
waiting for suggestions.......

It seem's you have your default gateway out of your eth0 address space.

You've to have some gateway in 10.16.10.0/24 network

yeah Vookimedlo,
i thought so......acc to networking rules gateway shud be between 10.16.11.0 - 10.16.11.24.......but then how come its working in win2k....?
neways...thanks 4 ur immediate reply....

hehe, u were right.....i asked my lan provider for another ip n another DNS server whichis in the range *.*.*.0/24.....n it worked
neways......thanx........
