Re: Screen Application

Thanks folks....I'm resurrecting an old PiB+ Jessie to experiment with all of these ideas. I'm aware of the "screen -r" command, but the screen session created by my rc.local itself is closed when my Python program ends, so there is no screen session to attach to. Rebuild in progress and experiments...

Hmmmm, that was what I suspected. I don't really what to restart that program/script, I really want to see the error messages which should be displayed when the program/script terminates. Oh well....RDK

Re: Screen Application

Perhaps I need a bit of clarification? Then when you re-attach to the screen you will be asked if you wish to kill the window by pressing 'k' or restart the process that failed by pressing 'r' When you say "restart the process that failed", I'm not sure if "process" means the screen session window o...

Re: Screen Application

Thanks for the information, I've started looking into tmux. However, in the mean time, is there an option or keyword that I can add to my rc.local command su xxx -c "screen -d -m /usr/bin/python /mnt/usbdrive/pgms/mypythonpgm.py" so that this session does not end if the program itself terminates?

Screen Application

I use the terminal multiplexer "screen" application a lot. I start a screen session in my rc.local at boot-up like this: su xxx -c "screen -d -m /usr/bin/python /mnt/usbdrive/pgms/mypythonpgm.py" where xxx is the user who will own the session. If I'm at a command prompt I start a screen session like...

Re: Installing RTL_433 software for my SDR Antenna

Folks, my RTL_433 system is working fine. However, now I want to make a change in one of the files and then make those changes "live". Do I need to repeat all of these steps:
  • cd build
    sudo cmake ../
    sudo make
    sudo make install
Thanks....RDK

Using a Raspberry Pi to translate/transfer IP traffic from the incoming IP address to another

OK, this is a bit unusual, but we have two IPS supplied Internet address which are in the same subnet, for example 66.55.44.3 and 66.55.44.2. We have a router that does not like its WAN addresses to be on the same subnet. So, my question, can I configure a Pi to accept traffic on 66.55.44.2 and pass...
