Veiwing log files
 

Hi all.

I'm trying to review log files, to see who previously accessed my server, and what commands were run. However when I try using nano, cat or vi to read /var/log/wtmp, just gobbledegook comes up.

I'm not actually expecting to find anything suspicious I just want to know how to do it, so I have tried to read this file on a Ubuntu machine as well as a Gentoo one, but the same problem happens for both, I can't read dmesg either. Are these files only available using a command or can I just veiw them as text files using nano for instance?

it's a binary file read by "last".

Hm,

:newbie:

Is there a way to see a chronological list of previous logins instead of just the last one?

Use the last command alone (you have not to give the wtmp file as argument, since last will read it automatically):

Vielen Dank.:)
