Help Needed using utmp file!
Hi.

I am working on a small assignment where i need to extract the login information of currently logged in users in a Linux client-server environment.I am able to extract only the userID,IP/HOST name,TTY,device name,GID,PID and login time using the structure 'utmp'.Also when i am saving the inforamtion in a particular file the GID and PID columns are blank in the saved file.Can Anyone explain why?..Smilie

Also i want to also display the information about the last access time of a user.Can this be done??.Smilie

Please Help!!:Smilie

How exactly you are using utmp ? locate on my local Fedora produces :
Quote:
locate utmp
/usr/bin/utmpdump
/usr/include/utmp.h
/usr/include/utmpx.h
/usr/include/bits/utmp.h
/usr/include/bits/utmpx.h
/usr/sbin/dump-utmp
/usr/share/doc/vte-0.14.2/utmpwtmp.txt
/usr/share/dstat/dstat_utmp.py
/usr/share/dstat/dstat_utmp.pyc
/usr/share/man/en/man5/utmp.5.gz
/usr/share/man/man0p/utmpx.h.0p.gz
/usr/share/man/man3/utmpname.3.gz
/usr/share/man/man5/utmp.5.gz
/var/run/utmp
Which one you are using and how ? Why not use "finger" "last" "who" ?
