I installed Ubuntu Linux 12.04 a little while ago to try it out and play around with it (hence I have no idea what I'm doing). I tried changing my home directory by editing the
/etc/passwd file, however I must have put in a bad value as I can no longer login to my account. Whenever I try it boots me out to the login screen before I can make it to the desktop. The only other account is guest (I hadn't gotten around to disabling it yet), and I can login to that just fine.
Since I know which file I screwed up, I can edit it back to what it was and hopefully login again. However, since this is a system file, it requires
sudo access to modify, which I don't have as a guest. Is there any workaround where I can somehow get
sudo access as guest so I can edit this file and login as myself again? Obviously I don't intend to leave that ability on guest, that would be silly.
I remember reading somewhere that I could ssh to localhost as a user with
sudo privileges, however I keep getting "connection refused". I believe it needs to be installed, and I hadn't gotten to that, and I can't do it now without
I did install Linux alongside Windows 7, so if there's some way to edit it via Windows, I could do that (though from my understanding Windows can't read the file system).
