Everything that was suggest in the previous post should be performed by root not a normal user. You would either open a console or login as root to the console. You would then enter the commands in the first example from the 'cli' command line.
As for the '/etc/resolv.conf' file you would need to use a text editor to enter your nameserver information. I choose 'vi' but others may use 'nano'. That is a personal choice. If you enter 'vi /etc/resolv.conf' then at the window you would get into the 'insert mode' by pressing 'i'. Once your in this mode you can then continue to enter the information I presented. Once complete you would press the 'esc' key then enter ':w<enter>' to write the file. To quit you would enter 'esc' then :q<enter>.
These commands could be entered together but I felt you should see the difference with the command mode. I suggest that you look at 'vi Commands
'. It may not be the easiest editor to use, but it is a standard that is widely used and very powerful.
Once this is complete you should be able to function with the 'inet'. Test it by 'ping google.com', if that's OK then your good to go. If you get errors or 'unknown host' then you have a 'DNS' problem. If 'host unreachable' then you have other issues. Do a 'ifconfig -a' and to get the kernel route table you can issue a 'route -n' from the cli. Post that information if you are getting errors.
I know this has been covered here on LQ. Do a search to get '*buntu' specific aid. What I have provided should get you on as long as your network device(s) are recognized and have the proper drivers loaded. If not then you will need to see what device you are using.
You can see if the kernel has recognized the device via 'dmesg' by doing a 'dmesg | grep -i eth' from the cli. Note that the vertical line between the commands is the 'pipe' '|' which should be a shifted '\' on your keyboard.
Another means to see your device would be to look at 'lspci -vv' to see if your device is there. You could pipe to 'grep' if so desired. Remember there is the 'man command', so if I need information on the 'ifconfig' I would 'man ifconfig
' from the cli. Please remember that 'man command' is your friend.
is a wonderful resource.
Plus the search engine here on LQ.
