How many machines connected to your system?
How to check that?
How to find how many ports are open on the system?

[Robert-Jan Goossens]

To mine or yours? :)

How to check that?
direct connections (telnet ssh rlogin etc)
# who -uH

How to find how many ports are open on the system?
# netstat -an
Or you can use lsof, if you do not have lsof installed, you can download it from the link.
# lsof -i tcp
# lsof -i udp

Vivekbhatia,

Open ports, you could use the netstat command or check the /etc/services file.

Jaime.
