Thanks for everyone’s assistance. I did not get a chance until now to update the situation…
Basically, this is what I did.. I did not look into the screen comment btw…. 1) When connected to the SDR via Ethernet cable, at the terminal type – nohup python namOfFile.py & 2) This will give you a PID (process ID) that is running on the Linux embedded system 3) Unhook the ethernet from the SDR 4) If running a VM as I was, close VM window 5) When run is done, reconnect Ethernet cable to SDR (assuming you never took Ethernet cable off of laptop) 6) Open a VM, and then a terminal window 7) Type the command – kill -9 PID (whatever PID was given in step 2 8) This should stop the process, but it did not for me.. so an extra step was to run another unrelated program that re-images/downloads the bit file to the FPGA. 9) Then quickly stop this new program. 10) Then I was able to ssh the created data file. Thanks again for everyone’s assistance, and I hope this may help someone in the future.

Unfortunately, I get the PID, but when I reconnect and go to terminal, the kill -9 PID seems to not stop it. I am currently using a VM to do this on a Windows OS platform. I am not sure if this is the reason… So, it seems that when I reconnect, I cannot kill the process. Any more advice?

I used GRC to create the flowgraph to capture samples to go to a file. But, I have to remove the ethernet cable to the E310. When this is done, it seems the data collecting process stops. Is there a work around using GRC? Or do I have to create another python code to run the GRC created python code for a certain amount of time using Linux or python code? If anyone has any advice or example code, it would be much appreciated. Thanks, Konstantin WHen you SSH into a machine, and disconnect the cable, eventually, SSH will drop the connection, which causes your session to be terminated, including any processes that you have have started from that session. You could look into the "nohup" command.... _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com<mailto:USRP-users@lists.ettus.com> http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com Could this be as simple as running your python in a shell under “screen” so the shell doesn’t die on disconnect and you can reconnect to the interactive shell later? https://www.gnu.org/software/screen/manual/screen.html
