Thanks, you were right. I found it in wtmp.1. The machine was turned off for about a month while I was on vacation, so it must I booted it up.
Does anyone know why, even though I have logged in...

So, I logged into my server today and ran the last command, which promptly informed me that the only login on record was my current SSH session. Is there some mechanism by which the login history...

I just installed Ubuntu 12.04 on a Dell Inspiron Mini, but when I boot it up, the screen goes black after the BIOS. I have discovered I can restart the display by pressing Ctrl + Alt + F1, which...

Just out of curiosity (I don't really plan on implement this), but is it possible to have an SSH server require a key and password authentication to log in? In my experience it has always been one...

From the language configuration screen, drag English to the top of the list, then click Apply System Wide. I think this is how you reset the language.

Try "adm" as the group name instead of "admin".

Well, generally users do not log in as root, and the root account is disabled on Ubuntu. Instead, administrative users can temporarily switch to root using sudo or gksu. Standard users can not do...

I have a desktop on which I installed Ubuntu 10.04 LTS, which I use as a file/print server. I installed the regular desktop edition, not knowing exactly what I intended to do with it, but now, I...

A script is a good idea. How exactly does one switch users from the terminal though?

I managed to get around a problem like this by setting up the printer as an LPD printer. Then I could find it without too much work. There is an overview at...
