Ethernet Working, no Internet

[CentaurHauler]

My home file server hard drive died last week, so I decided to try Mint7 with Gnome (was using KDE). Everything went smoothly on the install, and I'm up and running with file sharing in both directions with various Kubuntu & Mint KDE machines as well as XP and Vista. I'm rather liking this Gnome install, but I have no internet access - nothing can get out, including synaptic or package updates. I've hacked around an verified that the firewall is turned off. I've seen some references to others having this issue but have not found any threads with any real info yet - can anyone point me in the right direction?

Have you checked your DNS and gateway settings to ensure that they are correct? Are you receiving these settings via DHCP?

[CentaurHauler]

On this machine I've set a fixed IP and the gateway is correct. I don't recall ever setting up anything specific for DNS on my network before, but I'll look into it. I'll have to find where to set that up in Gnome.

I have a DSL modem connected to a router. It's been a long time since I messed with the settings there, but all of that is working fine from any other machine.

Did you reboot your router and Internet modem? Some of them remember last MAC address of previous computer and get stuck when a new computer is plugged in. Shutdown your computers, unplug both router and modem for 10-15 seconds, reboot them, make sure all LED's on as they should be and restart your computer.

If that does not work please open a terminal and type the following commands and post them to this thread:

Code: Select all

dmesg | grep -i eth0
inxi -N
ifconfig

Here's what I get:

It's working now - it did not know the DNS settings. Other installations of Mint with KDE and Kubuntu have discovered these addresses automatically, so I did not know to enter them.

Thanks for the help!

[lagagnon]

It's working now - it did not know the DNS settings.

It only learns the DNS settings if you correctly enter "DHCP" in your network config, or if your ISP does not use DHCP then you have to enter the DNS server IP addresses manually. So you must either not have checked the DHCP box or not entered the DNS server addresses.

[CentaurHauler]

I usually set them up with DHCP at install, only changing to fixed IP later. I believe that this time I set up the fixed IP during install, so it never had DHCP.
