Getting the following error while connecting to the source server using Plesk Migrator:
Looks like migration can not be started. The most common cause: wrong IP address, administrator login or password specified
The following error can be found in
stderr:ssh_exchange_identification: read: Connection timed out
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.1]
Source and destination servers are on different networks.
An intermediary intrusion prevention system bans
connections required for the migration are banned by an intermediary host. New connections are possible in few minutes.To reproduce the issue, execute the following command several times one after one in short period of time (id_dsa key should be replaced with actual one):
# rsync -rltgo -e "ssh -i /usr/local/psa/admin/.ssh/id_dsa.9p3YUB6W -p 22 -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no" /usr/local/psa/admin/plib/modules/panel-migrator/backend/lib/python/parallels/plesk/source/plesk/extras/pmm_12_5/ <source_server_IP>:/tmp/panel_migrator/migration_agent/tmp.mu3Q73SebA
Contact network administrator to allow multiple simultaneous connections for
on an intermediary IPS host.
