ssh problem between rpi and Jetson

Post by G4WIM » Sun Oct 27, 2019 3:05 pm

Wonder if anyone has come across this issue ?

I can ssh from my PC into Jetson and run various scripts etc and all is good.

However when I try the Portsdown RPI interface there seems to be no connection despite have all the correct passwords and IP addresses etc.

This problem only shows itself on a new image just built for the Jetson, all works ok on my old original image.

Seems the new image will only talk to my PC - I'm using the instructions from the wiki which are a bit dated so maybe something has changed in the meantime ?

Did you remember to create the ssh file in the root of the SD card?

Alternatively, perhaps you have a different user name on the jetson ?

Hi Mike,

the rpi side is working fine - problem is with the jetson. Almost as though I have wrong ip or user or password set but I haven't as they all work fine when I ssh from my PC - just the rpi which objects to this particular image.

Currently building another jetson image but headless just for kicks.

Still have my original jetson image which works ok - just thought I'd try the latest release from Evariste as he's made some changes to libdvbmod

Exactly how do you ssh?

ssh -l username ip_address ?

add a -v switch for more debug
