"Setting up Linux can be tricky for anyone at times. This difficulty can be compounded by making mistakes along the way. Luckily for many newbies out there there are places like #Linuxhelp which offer advice for newbies. It's unfortunate that we can't always be around to help. The above log shows the actual conversation that took place in the channel as recorded by the logs. We're sorry that nobody was around to straighten this out in the first place but that we should at least try to make amends by clearing things up now."

"There is no /dev/eth0. The lack of /dev/eth0 is not due to configuration issues or mistakes setting up the system, there just isn't one. About the only way you'll see network devices is via the ifconfig (interface configuration) program. By default ifconfig shows only devices which are both up and have an IP address..."

"The lo interface is the Loopback interface, the only device you're likely to see on a machine without networking. The sole purpose of lo is to route back to itself so it's not very interesting as far as networking is concerned. To see all the interfaces that Linux knows about then you'll need to use ifconfig -a which will show the interfaces regardless of configuration state. Please note that ifconfig is only capable of telling you about the interfaces Linux currently knows about, there's a good chance Linux doesn't even know about the Ethernet card."
