Monitoring whos connected to my pi

[Neddie]

Hi to all.
Is it possible to tell who is connected (via Ethernet) to my pi at any time.
I'm looking for something similar to Windows "Computer Management"
where you can see who has what files open ,shares etc.
I'm sure it's possible. I've tried things like nmap , but that didn't give me what I want.
I may have been using it incorrectly though.Cheers

You'll have to define what services you want to monitor the usage of.
Filesharing ( Samba ) is just one such service. SSH which allows users to log in to a shell is another service. There are probably another couple of hundreds different services you could install on your Pi if you wanted. Linux is not tied together the way Windows is, so there is no common tool to monitor all services that allow remote connectivity.

The traditional commands "who" , "w" , "last" and "ps" don't count ?

Also interesting : "lsof" , "fuser" .

Lets say monitoring SSH.
who , w , ps seem to work , but being new to Linux I need to figure them out still :0)
I don't know what half the info means :0(
Thanks

The other tool that's useful for shell logins (ssh, using the terminal) is "last" which will show who has logged in and when.
