ssh + ""exec request failed on channel 0"

[plegrand]

Hello,
i've got a little question about ssh on OS6450.
Everything works fine if i use ssh like that :

Code: Select all

ssh admin@192.168.1.1

But i would like launch directly a command and i've got an error message :

Code: Select all

ssh admin@192.168.1.1 dir
exec request failed on channel 0

Is there a way to do that from a linux client ?
Thanks for your help

The goal is to script this command : "show spantree ports blocking"

Hey plegrand,

did you find any solution on that?
It seems working on switches with aos 8.x, but not on 6.x

best regards,
alex
