how can I know which user has logged in?

What command is used to know which users are currently logged in the server?
I ran w command but it doesnt hint for the same?
I ran lsof command to know open operations but still clueless in understanding the o/p.

"who" or "w" or "finger" should have told you the same. What is that you get when you try those commands?

Along with those already suggested the "last" command may be of use.

Also, knowing how they login would help too. If they are accessing files using Samba for example, then smbstatus would show you that information.

I can recommend the last command though:

last | grep "still logged in"

Will show you who is currently logged in but it also shows you which terminal windows you have open, and if you're su'd to root etc.

your_shadow03:

Above query commands provide plenty of information.

But if you want a simple print of who are currently logged in just type

$ users <Enter>

hope this helps.
