Re: HTTP proxy via ssh tunnel

Where are you issuing the netstat command. The open port should appear on the client machine not the host you connected to. The -D option also acts as a socks proxy rather than http (can still be used in a browser, just set the right option). It also normally only works from localhost so it can onl...

HTTP proxy via ssh tunnel

Folks, I have remote access to a Raspberry Pi via ssh with login via public/private keys. I've read that proxy web browsing can be accessed using -D 8123 - tried this on numerous occasions and if I issue netstat -l I don't get port 8123 shown anywhere. Firefox seems to always default back to no prox...

WiFi Repeater Security

Folks,

Last year there was a bit of a scare with wifi security and although no evidence of hack taking place manufacturers were busy putting out security updates.

At the time, and I'm not sure why, repeaters were considered vulnerable.

Does anyone know if this is still the case?

Re: New Install - ffmpeg error

You can force reinstall with apt-get option "--reinstall" or you can first use "apt-get remove" or "apt-get purge". You should also do "apt-get clean" to force apt to re-download the package too.

Re: Arduino Type Relay

Thank you for prompt reply.

I have five Pi devices running projects but seldom had a need to use GPIOs other than I use UART to USB (Think that is what it is called) to actually set the Pi MicroSD card up.

Clarified well.

Arduino Type Relay

Folks,

The popular KY-019 5V relays used with Arduinos, appreciate they are 5V, can the R-Pi GPIO pins control this relay?

I think the 5V output GPIO pin is OK to power it, I am wondering about the signal to the relay which is 3.3V on the Pi.

Have you rebooted since doing the apt-get upgrade ?
All OK now, thank you for suggestion. Thought I had rebooted but appeared not at that time.

First time I think I've had cause to check IPTABLES rules before a reboot.
