My Redhat Linux box acts as gateway for files transfer between
my organization & another remote organization (which also has
a single point files transfer gateway)
Sometimes the network traffic shot up, so wondering are the best
ways to find out who & which programs are using up the bandwidth?
& if it's ftp protocol, I wud need to know the sender & recipient too
Is Redhat Linux 4.5 comes installed with nethogs inettop & iftop tools?
If not, where can I download copies that can be run straight away
(without compilation) & are they free of charge?
1)netstat -t -u –c (show continuously tcp & udp traffics)
For 2-4, not sure if we hv the tools installed
2) nethogs (shows a list of the top processes which use network bandwidth)
3) jnettop (shows a list of the top connections)
4) iftop (shows a list of the top connections, with bandwidth bars)
5) netstat --tcp --numeric
6) netstat –i
7) netstat --statistics –raw
