Security Onion not finding wired adapter!


Ok, so I am a student assistant working at a University, and we wanted to setup the distro Security Onion to help with some tracking. Security onion is based off of Xubuntu 10.04

When I ran it in virtual box it was able to see the wired adapter, but since it was on a sniffer port it was not able to use the bridged adapter setting. So I decided to dual-boot.

The installation went fine, except for downloading the snort rules (b/c of the sniffer port connection) and everything seemed to run fine. Until I did "ifconfig" and only saw the loopback adapter.

There were a couple of threads in other forums that mentioned error messages in /var/log/message but when I checked the adapters were not mentioned at all in my messages log.

Any help would be appreciated, Thanks!

Hi,

does
Code:
ifconfig -a
show your ethernet device?

If not, can you see it with
Code:
lspci | grep -i eth
?

Finally, do you know what "Security Onion" usually uses for configuring the network?
Eg wicd, network-manager, /etc/network/interfaces etc?

Thanks for replying,

Code:
 
ifconfig -a
does not show any adapter it only shows Lo, the loopback.

Code:
lspci | grep -i eth
shows intel corporation device 1502

It doesn't seem to have wicd or network manager, however I was able to find the interfaces file. But when I tried to manually write in my eth0 adapter and restart it still didn't show up (I was following a xubuntu tutorial).

Hi,

a quick google indicates that you might need the e1000e driver for that device, and that the kernel that comes with Ubuntu 10.04 does not have it. I seems that there is a newer kernel with the e1000e driver backported to 10.04. So, I think you have two options:

1. Install the newer backported kernel
2. Install a distro with a newer kernel that comes with the e1000e driver out of the box.

Once you have a kernel with that driver installed you should be able see eth0 when you "ifconfig -a". Then to get it running
you can add the following two lines in your /etc/network/interfaces
Code:
auto eth0
iface eth0 inet dhcp
HTH,

Evo2.

Yes! It worked! I just downloaded the driver from intel and after stumbling around the command line (and figuring out why ./configure doesn't work for this package)I got it loaded and running. Thanks for your help,
