Some application on my N900 is connecting to internet every now and then (matter of minutes). This uses massive battery but I am not able to track wich application is connecting.

How can I track wich application is using network (and possibly how frequent and how intensive the connections are)?
Is there a network monitoring command like "top" is for cpu and memory? Or some statistic log, to know usage, or at least wich application started the gsm connection?

Perhaps I set up wrongly some parameter in some application.. It keeps connecting way too often! I do not have internet-related widgets on my (only one) desktop. And now all chatting accounts are disabled. So?

Also, the connection seemps to be kept open even if no transfer is made.

Any ideas?

Thank, -Gus- (p.s. sorry for my lacking english)

open a terminal
type:

netstat -i

this should give you a list of processes and their currently active connections.

The -i option just shows the interfaces (similar to ifconfig), and the busybox version of netstat doesn't even support it. "lsof -i" works though.

I did it, but the output is huge (I had to find a way to input the pipe and use |more, and decrease the font size to fit all the text), and have near to no sense to me.. is there a way to track wich application is doing what? or an app that can analyze those logs? or a manual so I can understand something more? thanks


EDIT: found out that does output something more sensible.
I was about to try to sniff all the network and analyze it on a standard PC!

netstat -p -A inet (with netstat from net-tools, not sure about Busybox netstat):

Some information may not be readable by your current user and may require root access.

I've tried lsof -i which is a suitable alternative to netstat -p -A inet although the -c flag in netstat refreshes the information every few seconds; hence top-like. You can get similar functionality with lsof by issuing the -r flag. Something like iptraf or ntop may also be suitable alternative, or simply logging output of lsof/netstat.
