With no apps open, I'm still geting a small trickle of network activity
(as viewed by iStat Menus). This isn't normal.

How can I find out what's causing this? The only new software recently
has been Transmission, which isn't running.

netstat -p tcp isn't showing anything I'd personally get concerned by,
but for reference:

uther:~ jim$ netstat -p tcp
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address
(state)
tcp4 0 0 localhost.5204 localhost.49359
ESTABLISHED
tcp4 0 0 localhost.49359 localhost.5204
ESTABLISHED
tcp4 0 0 localhost.5204 localhost.49358
ESTABLISHED
tcp4 0 0 localhost.49358 localhost.5204
ESTABLISHED
tcp4 0 0 localhost.5204 localhost.49357
ESTABLISHED
tcp4 0 0 localhost.49357 localhost.5204
ESTABLISHED




Any thoughts?

Jim

netstat -anp |grep 5204, then ps auxww |grep <pid> ?

(should mention - I know you did a netstat, but without the n it can
miss it if its a well-known port and netstat translates it to
descriptive text)


Cheers,

The first hit for port 5204 was for some windows worm. MyDoom? No VMs
running? Run "lsof -i4:5204" to see what processes are doing the
talking. (The "4" is for IPv4.)

Netstat's -p option is Linux-only. It doesn't work on Macs anyway.
