tcpdump user help
I would greatly appreciate it if someone who uses tcpdump successfully on their N800 could provide a brief list of steps which must be taken to do this. I have tcpdump installed and I can run it, but no supported interfaces visible. I presume I have to have root access first?

Re: tcpdump user help
yes you need the becomeroot package installed. also, make sure that libpcap is installed. it is a dependent package that may not be fulfilled. not sure if that is still the case.
as with most linux apps, try the app name, in this case tcpdump, with a -h or --help parameter. you will get the most commonly used parameters and the required ones too. |

For the manpage of tcpdump, try http://www.tcpdump.org/tcpdump_man.html To run it, you either switch to root mode... or you make the tcpdump binary "setuid root", ie., "chmod 4755 tcpdump." The binary is installed by default on /usr/sbin. If your WiFi interface is active when you launch tcpdump, it will start listening on the wlan0 interface automatically. -- Denis |

Ok, I'm off and running, capturing packets. Thanks for the helping hand!
