Issue/Introduction

We are not able to make remote pu command as we get the error _command failed: communication error

For example, we are trying to clear niscache on a remote robot running the command from the primary hub (UIM_hub) to remote robot (ROBOT1)

C:\Program Files (x86)\Nimsoft\bin>pu -u administrator -p [email protected] /UIM_domain/UIM_hub/ROBOT1/controller  _nis_cache_clean ROBOT1

May 18 13:18:44:159 2 pu: _nimInit
May 18 13:18:44:164 2 pu: nimCharsetSet() - charset=
May 18 13:18:44:173 0 pu: Failed to read a valid probe_crypto_mode from controller. Assuming pre-FIPS and using TWO_FISH
_command failed: communication error

Cause

The _command failed: communication error can be seen if the probe address (eg. /UIM_domain/UIM_hub/ROBOT1/controller) is wrong and the probe is not reachable from where the command is executed.  

Environment

Release : 20.3

Component : UIM - CONTROLLER

Resolution

Verify if the address mentioned in the command is correct and that the remote robot is in the same domain wherefrom the command is executed. 

 

 

Additional Information

•  For debugging purposes It is possible to add -d 5 to the command to obtain additional information about the error.

Example:

 

C:\Program Files (x86)\Nimsoft\bin>pu -d 5 -u administrator -p [email protected] /UIM_domain/UIM_hub/ROBOT1/controller  _nis_cache_clean ROBOT1

 

•  The error: Failed to read a valid probe_crypto_mode from controller. Assuming pre-FIPS and using TWO_FISH can be safely ignored

 

•  Run Probe Commands from a Command Prompt (broadcom.com)
