Re: #draws #draws
A suggestion if I may. The tcpdump command will generate a lot of data and it becomes problematic to capture it from the screen and/or the buffer will overrun and you will miss packets. I have found it much easier to capture into a file. From there you can easily move the file of the output where you need it.toggle quoted messageShow quoted text
sudo tcpdump -e -vvv -i wlan0 -w filename.txt
The program will provide a count of the number of packets captured, press CTRL-C to stop the capture and close the file.

There are a couple of possibilities. It is possible to configure Direwolf to gate traffic to the Internet. If you did NOT touch the direwolf.conf file then you are most likely OK since my scripts do not configure Direwolf to do this. It is possible that you have configured Xastir to gate packets to the Internet. In Xastir check Interface -> Interface control, select Device 0 Networked AGWPE, click on properties. Verify under 'IGate Options' that 'Disable all IGate traffic' is selected. You might have an application loaded on your RPi that broadcasts on all network interfaces. Verify that iptables has the policy the install scripts should have setup. Run script iptable-check.sh, you should see these addresses are dropped 184.108.40.206, 220.127.116.11, 18.104.22.168 To understand your problem I would need to look at the offending packets that your coordinator is referring to. For instance is he referring to broadcast/multicast packets from some application or is he referring to APRS packets gated to the Internet by you. You could ask your coordinator to send you a copy of the packets they saw or you could capture them yourself. # From a console window # Install tcpdump apt-get update apt-get install tcpdump # Run tcpdump sudo tcpdump -e -vvv -i wlan0 Hope this is helpful. /Basil n7nix okiejim <kd6vpe@...> writes:My Draws hat with Xastir is sending packets out over my wifi when I have it on. When I turn off my wifi it sends the packets out via a normal digipeater on the rf side. I found this out when a coordinator in the area said I was doing this and I was wondering what I have set up wrong to have it doing this. I do not have any digi setup on Xastir that I am aware off. Can anyone help direct me to what I did wrong. I want to wifi on so I can remote desktop to the Pi. Thank you *.*
