Take the 2-minute tour ×  Whenever I log into a server using
ssh. The prompt gives me "last login" information. I was
wondering where this information comes from. How can I remove
this record so when someone else log into the same server, the
person would see my login info with my ip in it?  So how can I
do this? For the record, I am not hacking someone's computer and
the server runs Ubuntu 12.04.  EDIT: which file logs this kind
of information? If I find the file, then I can do anything to it
as root.   share|improve this question Ubuntu 11.04 != Ubuntu
12.04. –  Michael Kjörling Jul 2 '12 at 13:17 Note that this
information can also be requested by running last $USER. –

–  Gnijuohz Jul 2 '12 at 13:41 != is commonly read as "is not
equal to". You wrote Ubuntu 12.04 in the text of the question,
but used the ubuntu-11.04 tag. The two are not equivalent, so
one or the other must be wrong. –  Michael Kjörling Jul 2 '12 at
