I'm on dial-up, and as soon as I fire up Firefox the modem lights start flashing away, and my effective modem speed seems to be at least halved. So, in addition to trying other, less "chatty" browsers, I wanted try and analyze the traffic to see if I could block it or modify Firefox to stop it. Has anyone used tcpdump? I was looking at wireshark, but it said it was a graphical version of tcpdump, and tcpdump is already installed. However, when I run it, even according to the examples, it doesn't catch anything at all. I've tried the following commands, as root: tcpdump host <myhostname> tcpdump -v host <myhostname> tcpdump -v host <myfullyqualifiedhostname> tcpdump -v host localhost Does anyone have any tips?</pre></blockquote></div> -- Sent from my Android device with K-9 Mail.
