Manually Connecting Ethernet

DateReadtime 3 minutes Tags

I broke my computers internet installing wicd.

Getting internet back

  1. Check the interfaces

    $ ifconfig
    
  2. Check eth0 explicitly

    For whatever reason, my eth0 wasn't showing up until I explicitly specified it.

    $ ifconfig eth0
    
  3. Get an ip address

    $ sudo ifconfig eth0 192.168.1.100
    
  4. Connect to the outside internet

    sudo route add -net 0.0.0.0 gw 192.168.1.1
    
  5. Make dns resolve

    • Edit /etc/resolve.conf to include:

      nameserver 8.8.8.8
      nameserver 8.8.4.4
      

Fixing wicd

  1. Try wicd-curses

    Wicd-curses fails to start up. With a long python traceback

    Can't connect to the daemon, trying to start it automatically...

  2. Wicd's daemon

    So, Wicd's daemon isn't running. Lets check that:

    $  sudo service wicd status
    * wicd is not running
    

    And try and start it?

    $  sudo service wicd start
    Traceback (most recent call last):
      File "/usr/share/wicd/daemon/wicd-daemon.py", line 1859, in <module>
        main(sys.argv)
      File "/usr/share/wicd/daemon/wicd-daemon.py", line 1708, in main
        os.symlink(dest, backup_location)
    OSError: [Errno 17] File exists
    

    Manually?

    $  sudo wicd -foe
    Traceback (most recent call last):
      File "/usr/share/wicd/daemon/wicd-daemon.py", line 1859, in <module>
        main(sys.argv)
      File "/usr/share/wicd/daemon/wicd-daemon.py", line 1708, in main
        os.symlink(dest, backup_location)
    OSError: [Errno 17] File exists
    

    Ahh, lets look for that issue.

  3. Fixing daemon

    I found a bug on launchpad and basically, /etc/resolve.conf points towards a relative link rather than an absolute one so when wicd copies the symlink it points to a different path. I did this:

    # rm /etc/resolv.conf
    # ln -s /run/resolvconf/resolv.conf /etc/resolve.conf
    # rm /var/lib/wicd/resolv.conf.orig
    # ln -s /etc/resolv.conf /var/lib/wicd/resolv.conf.orig
    

    Then I retried starting up the daemon and success!
