problem with starting a shell - jnpr.junos.utils.start_shell

‎11-13-2018 09:48 PM



I am trying to login to shell, save a long output in a file and compress it. Then transfer the compressed file. I am getting below error when I attempt to start shell. 

Goal is to save the output in a file and then transfer it after compressing.  This is to save data transfer time, output is long enough that regular RPC takes very long. If starting a shell doesn;t work, is there any other way to save output locally on router in a file from RPC? 


Also, I am using port: 22 for netconf. Any idea what can be wrong? 


Thank you,
