“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 127.0.0.1 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.”
