I work in college network. I have shared my computer password with few friends. So any of them can ssh/ scp on my system. Is there any way to generate the log of connection ( if some one make connection through ssh or copying using scp ) data. ( Just in case to see what they do on my system ) ?
I am using openssh-server in ubuntu 10.10 system.


It seems to me that we can generate log or can get notification for ssh connection ( by looking SSH_CONNECTION parameter ) but no way for scp, or is there any ?

EDIT: I little bit of solution : create a rc file inside .ssh directory and create log from that rc file.
