I'm using ifconfig to monitor how much data I'm using, but it seems
pretty high. Is there a simple way to see why I'm using so much data?

Also iftop and lsof with some clever regex-ing if you want to see what program
drives the connection.

Thank you, iftop is great:

iftop -i ppp0 -P

I use vnstat. You can get PHP frontends for vnstat that make it nice
and groovy as well.

nethogs will show active network activity

Oops, I somehow sent that while composing. I was saying, nethogs will
show active network activity by program, so you can see who is using
network data at that moment, in a top-like fashion. Not a "how much
has it used total", but a "how much is it using right now". Here's an
example:

NetHogs version 0.7.0

PID USER PROGRAM DEV SENT RECEIVED
29641 root git wlan0 0.929 0.649 KB/sec
29620 root /usr/bin/svn wlan0 0.187 0.269 KB/sec
29509 paul sshd: paul@pts/1 wlan0 0.883 0.136 KB/sec
29612 root git wlan0 0.119 0.131 KB/sec
29591 root /usr/bin/python wlan0 0.000 0.000 KB/sec
0 root unknown TCP 0.000 0.000 KB/sec

TOTAL 2.118 1.185 KB/sec

That is REALLY cool. I can't believe I never knew about this before.

That's a great tool. I couldn't get it to work with ppp0 until I
emerged the ~amd64 version.

+1 - this looks really useful.
