Re: Temporarily redirect a port forward

Another possible solution, if the remote RPi has unfettered outbound access to the internet, is to use a third-party 'reverse ssh tunnel' service such as those offered by Weaved or Dataplicity. "Weaved" looks really interesting. X11 forwarding with Putty and Xming worked, but was shaky, jerky, and ...

Re: Temporarily redirect a port forward

1) You have ssh access to the remote RPi. Does the RPi have administrator access to its local router? Because if so you could use that to modify the port forwarding configuration of the router. If I was sitting at the remote pi, yes I would be able to configure the router through a web interface. T...

Temporarily redirect a port forward

I have a remote server on a remote network in a vacation house location. The router is presently forwarding port 8765 to port 8765 on a remote network pi. The sshd daemon on the pi is set up to accept both port 22 & 8765 connections. On the above remote network pi, there is a web application I'd lik...

Re: Help to understand ssh port forwarding

Thanks YCN - your second suggestion with the -g option did the trick.

I don't know why I have such trouble with ssh port forwarding - too many options!

Re: Pi2: Startx problem. G2D_23

Same problem here - New Model B+ using noobs / Raspbian install. Only the trash can shows on the desktop and the screen jumps up and down every few seconds?

Re: Error compiling wmr100 & libhid

OK, solved - before compiling, run the command: export PKG_CONFIG_PATH=/[supply path details here]/libhid-0.2.16/pkgconfig/ ...and if you get a "too many arguments" error in wmr100.c, change the following line: /*zmq_send(wmr->zmq_sock, buf, len, 0);*/ zmq_send(wmr->zmq_sock, buf, len); Hope that he...

Re: Photovoltaic/solar systems monitoring

Yes, I was able to receive the one second interval 49 byte output from the Mate. The usb to serial converter (with no powered usb hub) is apparently outputting enough voltage (on 4 & 7) to power the Mate serial port. I haven't as yet done anything with the data, but it's coming through and agrees wi...

OK, so I answered my own (second) question.

Re: Photovoltaic/solar systems monitoring

Hi - First, I have an Outback FM60 with a Mate-b in a remote cabin - and am very interested in your project. Second, I have been trying to get the pi to receive the Mate data. I have a usb to serial adapter which I plugged directly (all pins straight through) to the mate. I'm using minicom and set t...

Re: Raspberry Pi Case from Bud

Ordered two of these on Monday and received them Wednesday - I'm in the USA and ordered them from Newark/element14. Paid less than $20 total including shipping. (Again, this was for 2 units) The case is very simple but effective - not air-tight, but not designed to be. It effectively shields the boa...

Debian Success with a few glitches

I was basically successful getting my pi up and running with the current Debian download. I have another Linux machine, so I followed the "dd" instructions from the MagPi magazine (issue 2) to write the file image. I waited over 20 minutes for the the "dd" command to complete - it never did. I could...
