Kubuntu DHCP issues


Hey guys, I'm trying to get myself up to speed on linux here for means of learning and being able to provide increased network security via the tools for auditing and tweaking that are available for Linux...

Having said that I'm having a heck of a time... I first tried to use Suse, but once it was installed the silly thing needed me to install every app under the sun in order to compile and run Nessus. I ended up giving up after a while because even after installing the apps to install the other apps, the machine still said those needed apps where missing (and I was working with a guy who knew Linux very well).

So I moved on to Kubuntu (mostly because I like KDE -its flashy I got it installed after numerous Grub Geometry issues (it needed a small partition specified as /boot). Now I can't get DHCP, when trying to connect wireless or hard wire... I get green bars, but the machine does not connect and get DHCP... SO, I went into the configuration menu to take a peak at the network settings. When I click network settings it tells me to log in as Admin (because everything is all greyed out). I do that, it brings me to a smaller screen of Network things to click on, but when you click on them, it tells you that you need to log in as admin again.... Its a vicous circle that has no resolve.

Can I get some help here guys? I'm trying to get some traction with linux so I can futher myself as a tech, because it is the ultimate os for techs to use.... I'm just pulling my hair out trying to learn it :-)

Wireless is going to be a pain depending on the card you have -- I'll tell you that straight away. As for your ethernet connection though, it's not that difficult.
Try this command:
Code:
ifconfig -a
You should see output similar to the following:
Code:
eth1      Link encap:Ethernet  HWaddr 00:40:05:88:09:9F
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::240:5ff:fe88:99f/64 Scope:Link
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:329063 errors:0 dropped:0 overruns:0 frame:0
          TX packets:366642 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:33971290 (32.3 Mb)  TX bytes:441528027 (421.0 Mb)
          Interrupt:9 Base address:0x2f00
The bold type is what your looking for. Now, this is my secondary NIC (my linux box is a router). Where I have eth1, you'll likely have eth0. The inet address is your computers IP address. If you don't have an eth0, it means the card is not being found. Please post the output of
Code:
/sbin/lspci
if that's the case.

Please post back with further trouble.

It looks like it sees the cards well enough to me... It lists Aterhos Communicatinos AR5212 NIC and the gigibit ethernet controller at the very end. But there was no INET address listed... Any thoughts, or should I switch to a different distro that will suit my goals better? Suse worked great for getting up on the net without any hassle, I just couldn't install much of anything beyond firefox or RPM's.
