BUG: Exception: Error reading SSH protocol banner #4

Closed artgmolina closed 2 years ago

artgmolina commented 2 years ago

It happened for a UCS I tried to use.

The target IP address (-m MGMT_IP) needs to be a working BIG-IP instance where you can log in with the root user and password (-p PASSWORD). The tool (f5-journeys-lab-ucs-modifier) connects to this target unit and copies some basic configuration (mgmt IP, route, root&admin passwords...) to replace in UCS.
