Linux Mint: Enabling a NIC
- 
 So I have here a machine running on Linux Mint. What exact command lines do I need to run to enable the internal Ethernet port? The graphical interface seems to have no options for enabling it. 
- 
 That means it didn't detect a connection. If it had one it would be on already. What hardware are you on? 
- 
 HP Compaq DC 7700 
- 
 Where did that come from? Is that Andy's old development workstation? 
- 
 What is the output of ethtool eth0 
- 
 It is reported as working: 
- 
 And the output of ifconfig 
- 
 I have no idea where it came from, I was just told to put Mint on it  Everything else works perfectly, plugins and system tools all. But it says the NIC cable is unplugged. I checked the connections from the machine all the way to the Modem, and everything is fine. Everything else works perfectly, plugins and system tools all. But it says the NIC cable is unplugged.

 If things are working, something is probably connected. Do the ifconfig and ethtool output. That will tell you if you can safely ignore or if there is a problem. Totally possible it's eth2 or something equally stupid, where it bound up an ethernet interface and it really doesn't do anything.

 Got it working, thanks guys.

 What was it?
