Re: Puzzler: routing for three interfaces (wlan/eth/ppp)

Thank you, firedrow, for your feedback. I more or less gave up and have some kind of solution now. In my setup tun and ppp work at the same time (I only added interface ppp0 to the network settings) with a split routing where specific IPs are reached via the vpn and all the rest goes through the reg...

Puzzler: routing for three interfaces (wlan/eth/ppp)

For setup purposes my Pi is connected either via wifi or LAN to my internal network (192.168.1.0/24). WAN gateway, VPN server and DNS is 192.168.1.1. PPP dialup with a 3G stick is set up and working. What I am struggling with is setting up routing. Hopefully somebody here is able to help me. if wlan...

Re: Setting up Dynamic DNS to view Pi camera stream

No, disabling UDP forwarding wouldn't change it to the better. 1. Do you know your Pi's internal IP address (most likely it starts with 192)? Let's call this "[intIP]". (From a command line "ip addr show" will give you some numbers, among them the IP address of your Pi, to limit the output you may e...

Solution for offline wifi setup

Currently I have a working roaming wifi setup using a WPA supplicant conf file with the details for all known networks. The Pi runs headless and it is quite annoying to add a new network without being connected (one of the stored networks is my phone's AP, with this I can SSH to the Pi and edit the ...

Re: Setting up Dynamic DNS to view Pi camera stream

If your Pi is behind a router/firewall you need to set up port forwarding. Your router doesn't let anything in unless there is port specific forwarding set up. Find your router's port forwarding setting and set it up to route TCP requests for port 8080 to port 8080 on your Pi's internal IP address.

Re: Motion - MMAL camera

Re: Infrared receiver, destruction possible due to pinout er

Update: I followed the pinout from the spec sheet of a similar looking module and it works. I am amazed that something can be hooked up directly without the need for resistors or anything else. I wonder if I can connect a photodiode in a similar fashion. I'll hunt around.

If that's the only risk, the IR module going up in flames, then I can live with that.

The pin out seems fairly standard. Pin 1 data, pin 2 ground, pin 3 +ve. I can't see you damaging the Pi or the receiver.
