RE: Network monitoring software
-
Are you talking about monitoring services on your local machine (be it server, workstation, etc.)? If so, then a simple
[code]netstat[/code]
will tell you quite a bit, although it is not a GUI and not very pretty.
Likewise, this will give you lots of output, but in a terminal:
[code]tcpdump -i [ethN][/code]
The lsof command also works with network services, e.g.:
[code]lsof -i4[/code]
just lists currently running processes that are using IPv4.
TIP: if you know what port something is listening on/talking on, you can look it up in /etc/services and sometimes get a description for that service, according to the IANA anyway.
For gui tools (neither of which i have tried in some time), you can check out Nagios and Cacti. I don't know how app-centric they are, but they're definitely intended to monitor network traffic.
