Hi There,

127.0.0.1 is what is known as the loopback interface. It is the local ip address of your ethernet card, so you're not pinging outside the box, you're just looping back. Thus it (should) always work.

the command using the command `
Code:
ifconfig
` at the prompt to show the configuration of your current interface. If you have a single ethernet interface it should display as "eth0" which is the first ethernet (interfaces in linux number from 0 up).

The command `
Code:
netcardconfig
` can be used to specify your IP address configuration. It is menu driven and can be run from a command prompt. If you are behind a router that uses DHCP, then you should select DHCP instead of a static address.

During the installation it should have asked you if you wanted to Broadcast for an IP or something to that effect. The normal answer, behind a home router, is Yes. THis will enabled DHCP, however you can also enable it from the netcardconfig program.

To check connectivity to the rest of the world, look at the output of ifconfig once you complete your netcardconfig and if you have a valid IP address try to ping a host in the outside world, for example "
Code:
ping www.news.com
"

Also try tracing the path to it to see where your packets go:

Code:
traceroute www.news.com 

(or better yet, us an IP in case your DNS isn't working)

Code:
traceroute 24.222.0.5


(CTRL-C will break you out of it)

Should show something like this (your path will be totally different but the point is that you see the routers from your house to their server):

Code:
[root@blackops ~]# traceroute 24.222.0.5
traceroute to 24.222.0.5 (24.222.0.5), 30 hops max, 38 byte packets

Try this.

edit your /etc/network/interfaces like
Code:
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp

you really should open another thread for the sound issue, but any reason why you installed alsa instead of using the one that is already installed?
