ive got a qube 3 looking to install security software. what i would like to do is see what users are loged in, how long and what they are doing. i would also like users to be able to login via vpn and have a "shared" folder (like in windows network neighborhood) that they can pull up to view files...

any help would be appriciated

You can use the "ps" command to see what users are doing.

ps -auwxx

that will show you a lot of server activity.

If you want to see the exact keystrokes of your users, you can get TTYsnoop but if they are connected through a secure protocal such as SSH then you can snoop on them. Telnet on the other hand will work.

You could try installing hostsentry. It will give you reports on user interaction, though maybe not as much detail as you need
