Not able to connect to internet eth0 (dhcp)

[bpelleri]

Hello folks,

I am a non-geek. I booted up the system, but the internet connection is not working. I have an ethernet cable and I assume it uses this "dhcp" thing and "broadcasts for IP".

The internet works well with DSL; I got it started there by clicking the control button "iwconfig" (I think). I am guessing that I have to type something either at boot or in a terminal in the JWM environment.

Thanks in advance,
Brian

iwconfig would be for wireless.
If you typically use an ethernet cable, then open a shell and type ifconfig.
Do you see an entry for etho? Post results from ifconfig here.

Sure, here is the ifconfig result:

It looks like it is working to me.
Cat /etc/resolv.conf and see if the right nameserver is listed.
run 'route -n' and make sure your default gateway is your DSL router.

glc@sharp-glc:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         192.168.0.254   0.0.0.0         UG    100    0        0 eth0
glc@sharp-glc:~$

Here my gateway is 192.168.0.254

maybe a suggestion:cpanel, netcard config, choose DHCP and hit yes. it should run udhcpc which will get an ip for your machine.

I'm not sure what you mean by that...

Here is my kernel IP routing table:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0           255.255.255.0  U       0        0        0 eth0
0.0.0.0         192.168.1.1       0.0.0.0             UG    100     0        0 eth0

Sometimes it works (especially if I boot up TC after I just had DSL or some other OS working the internet connection properly), but it is certainly not a reliable thing.

I'll try netcard config - DHCP (even though I don't have a wireless net card).

BTW, I have the same trouble when using Slitaz and PCLOS, too.
