help with internet setup

hi, just installed 11.2, but can’t setup the internet successfully.

on campus, have to use dhcp, which seems to be working, since i can get the ip address right.

just can’t connect to the internet, or even the DNS or DHCP sever. here is the information you might find useful:

dni165-1:/home/gui # ifconfig
eth0 Link encap:Ethernet HWaddr XXXXXXX
inet addr:68.181.XXX.XX Bcast:68.181.169.255 Mask:255.255.254.0

loopback * 255.0.0.0 U 0 0 0 lo
default 68.181.169.254 0.0.0.0 UG 0 0 0 eth0

but sometime the result is a little different.

Is your net mask correct. Your setup shows 255.255.254.0 which may be correct, but the most common is 255.255.255.0 which may be your problem. Also if your using dhcp and a direct connection to the internet (i.e. no router or gateway) you should be able to use netorkmanager instead of traditional ifup which may make your network discovery simpler.

the mask is correct. i tried to open networkmanager, but there is no response, not sure what’s going on.

Open Yast - Network Devices - Network Settings

Select the device listed as eth0 and choose edit
Then just click through with next/accept

Usually that’s all that’s required

If you are not using wireless then stick with ifup.
