Using the pu utility to perform an action a remote robot fails with a "communication error" error message.
Running the pu command to a remote machine, will fails with one of these error messages:
C:\CA\UIM\bin>pu -u administrator -p PasswordXXX /W2008R2_domain/W2008R2_hub/WIN-2ECKORD7A85/controller
Oct 27 16:53:12:473 pu: SSL - init: mode=0, cipher=DEFAULT, context=OK
Oct 27 16:53:12:474 pu: nimCharsetSet() - charset= _command failed: communication error
or
Dec 18 14:46:35:625 pu: SSL - init: mode=0, cipher=DEFAULT, context=OK
Dec 18 14:46:35:657 pu: nimLogin request login failed 10.162.31.76/48000 (login failed) _command failed: communication error
In the command:
C:\CA\UIM\bin>pu -u administrator -p PasswordXXX /W2008R2_domain/W2008R2_hub/WIN-2ECKORD7A85/controller
The robot name is case sensitive, after correcting it to Win-2ECKORD7A85, all worked fine
