Attempt to generate migration using command panel-migrator generate-migration-list fails with error:

[ERROR] ABORT (by exception): fetch info from source servers
[ERROR] Failed to perform action: Fetch data from source H-Sphere
Cause: Error reading SSH protocol banner
That is a critical error, migration was stopped.


SSH connection timeout has been reached during connection from PA Management node to H-Sphere server.


Login to PA Management node and change parameter self.banner_timeout at /opt/panel-migrator/thirdparties/python/lib/python2.7/site-packages/paramiko/ using text editor. For example, as following:

[root@pa ]# grep "banner_timeout = " /opt/panel-migrator/thirdparties/python/lib/python2.7/site-packages/paramiko/

self.banner_timeout = 60        # how long (seconds) to wait for the SSH banner
