Re: Where's my bandwidth going?
That's OK, I've mostly got it figured out. Having many (10+) tabs open in Firefox is the main culprit, especially when some of those pages refresh. I don't trust Yahoo mail anymore, even though I close that tab. mc seems to use bandwidth for something too. I've got pktstat running now, I like systat too and pftop. tcpdump -n is pretty noisy, with some intentional download with wget going on.

Re: Where's my bandwidth going?
The suggestion on this thread are interesting. But tcpdump -n is pretty manageable over a modem link and shows you exactly what you want to know, not just a summary of it.

You can watch each packet with "match log(all,user)" in pf.conf and running "tcpdump -enipflog0 -v". The *second* pid reported shows the associated program. (The *first* pid is that of the pfctl instance which added the rule). Or it may be easier to use some other program to grab the bandwidth figures (darkstat, perhaps?) and then look in pflog to identify the pid, in which case the per-packet information is probably not useful so maybe just do "match log(user)" which will just show one entry for each state that was setup.

To see the ins and outs of our network traffic, I like using pftop. I looked at iftop too, it has an interesting display but pftop was more useful for me. -Barry

Where's my bandwidth going?
I'm on a modem, so there's only about 3 K/sec anyway, but is there anything that'll show me at least pids of what's using bandwidth? I've learned to close Firefox and even mc sessions I'm not using, and I'm watching a wget download and pftop and "netstat -b -I tun0 -w 1". I've got it under control right now by shutting off my wireless access point because my Kindle Fire was talking to s3.amazonaws.com. Poking around in userland ppp sources I see something called netgraph. How do I use that and what does it do? Alan
