X-NetStat Professional v5.58

X-NetStat Pro will display information
on all your current Internet and
network connections in a graphical
interface. These connections are
established each time you visit a web
page, send an instant message, check
your email, or anytime you do network
activity that requires you to connect
to another computer.

They also appear when outside
computers attempt to connect
to your machine, authorized or not.
Information shown includes local and
remote addresses, local and remote
ports, the status, the age of the
connection, how much bandwidth/
traffic the connection is using, and
the program EXE behind it. It's kind
of like Internet/network radar, and
you can even kill unwanted connections.
