For those of us used to Windows management tools, getting a comprehensive list of data regarding installed hardware on a Linux box can be a little daunting. Whilst recently migrating a virtualised ubuntu box, I needed to find out just what network hardware was in use.
Within a linux shell, type the following
lshw -class network
This will produce a full list of all installed network hardware. For newbies, the define name you are probably looking for is called logical name.
No matter how many times I have installed and configured Linux, I can never remember the name of the configuration file that stores the DNS/Nameserver details. This really only applies if your Linux machine is using a static IP address. In most scenarios, it does not apply to DHCP clients.
DNS server settings are stored in /etc/resolve.conf To edit this file, enter the following command from the shell
$sudo nano /etc/resolv.conf
(If you have installed XWindows/Gnome, you can use sudo gedit /etc/resolve.conf instead)
Add the entries for your DNS or nameservers as follows
nameserver <IP address of DNS server 1>
nameserver <IP address of DNS server 2>
etc…
