can you please clarify "go online"?? normally this sort of thing sounds like a DNS issue, but you've not mentioned what actually does work and what doesn't. can you ping internet sites by ip for example?

OK, so yes, that's a DNS issue. is a valid DNS server listed in /etc/resolv.conf?

DSN1 and DSN2 are both displayed as "xxx.xxx.xxx.xxx" (literal value not hidden value)

The whole /etc/resolv.conf file is:

----------------------------------------------------------------------------------------

# Generated by NetworkManager


# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

Thanks.

After checking that file I was able to add my DNS and Domain to the ifcfg file and the internet works now. this message is actually from the Fedora 10 computer

I'm having a similar problem to ct_hamster. I'm using Ubuntu 8.10
However my issue (I think) is with the proxy. I have DNS listed in my resolv.conf file. I am able to access internal network. Not able to browse external websites or ping the sites using their IP addresses.

eth0 Link encap:Ethernet HWaddr 00:12:3f:40:c4:45
inet addr:10.128.159.9 Bcast:10.128.159.255 Mask:255.255.255.0
inet6 addr: fe80::212:3fff:fe40:c445/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1505 errors:0 dropped:0 overruns:0 frame:0
TX packets:231 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:160311 (160.3 KB) TX bytes:26299 (26.2 KB)
Interrupt:16

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:90 errors:0 dropped:0 overruns:0 frame:0
TX packets:90 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:18911 (18.9 KB) TX bytes:18911 (18.9 KB)

resolv.conf:

# Generated by NetworkManager
domain j*****.a** (internal domain)
search j*****.a**
nameserver 10.1**.*.**
nameserver 10.1**.*.**

Any ideas?
