I was repartioning my hard drive, and I was in the process of moving a partition left and resizing it, when I accidentally hit the "Cancel" button. While the partition itself was already resized, the moving of the file system itself had not begun moving (it was in a 'read-only' phase of the process at the time), and so I am still hopeful that it is still possible to recover the file system, and that everything should be intact. However, it is inaccessible by any means I can think of, and located somewhere in the middle of the new partition, though I don't know exactly where.

Is there any tools I could use to find the location of the file system or recover it or really, just anything to get access to my files there? Any help is appreciated.

I have a computer running SSH that I would like to give my friends access to, but I do not want them to use my internet connection through SSH tunnelling (although I'd like to do so myself). Is there a way to have a log of when SSH tunnels are created and by which (local) users, or, if that's not possible, only allow some users to do so?

I have a machine that I just installed Ubuntu Server on. The only problem is that I do not know how to connect it to a wireless network, and I cannot use a network cable to connect it to my router.

When trying to list the network cards, only the loopback interface showed up:

$ ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric 1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

which was unexpected, as both my Ethernet network interface (eth0) and wireless network interface (wlan0) showed up when doing the same in a fresh installation of Ubuntu Desktop 10.10.

So, my two questions are:

  • how can I install the wireless drivers (and packages I could download etc.) and/or set up the wireless network interface to work properly, and
  • how can I connect to a WPA-encrypted wireless network from the command line?

EDIT:

I ended up uninstalling Ubuntu Server and installing Ubuntu Desktop instead, then configuring the wireless network through the GUI and making it boot into command line instead of GNOME.
