no x on this box, its a server

 

[kalster]

netstat -e - s

not sure if the level of detail is what you want

edit: not per process, only per interface, damn sorry, i wish my linux box wasnt down i cud try out some stuff

 

[Ameesh]

yeah i need per process so i can track a problem down.

is there nothing like perfmon in linux?

I can't think of how to get a per-process bandwidth usage listing off hand, since I've never had to do it.

A good starting point would be to ask yourself what you think is sucking up the bandwidth. Check to see if anyone is downloading gratuitous ammounts of data from Apache or ProFTPD, see if rsync or bittorrent are running, make sure NFS and SMB exports haven't been mounted by an unwanted user.

It might help if you read the link page. I have always use netstat to look at what coming in & out, but you could try the slick Netstat Live tool.

Ps. You should know better for a Lifer that this is OT not Network or OS forum.

You could aso try IpTraf
I don't think it does a per process view but you could always monitor the ports over which the traffic is coming from and take it from there.

Edit little error

look for ethereal on google. I use it to find out which computers have certain viruses that bogg down the network.
