Hi,
I am attempting to setup replication between two hosts running Centos 6.4
and Dovecot 2.2.5. My users are real unix users, so I am trying to run the
replication as root user, so that it has the appropriate permissions to run.
I have two users at present syd1 and syd2, and the two hosts are called syd1
and syd2 as well.
When I start Dovecot with the settings below, nothing happens, and the two
mailboxes remain un-synced. There are no errors in the log, just Dovecot
starting successfully. I have attempted to run the dsync command manually
from syd1:
ssh -q -o StrictHostKeyChecking=no -i /home/vmail/.ssh/id_ecdsa root at syd2
doveadm dsync-server -usyd1
and I get the following in response, but this might be normal:
VERSION dsync 3 1
Hhostname sync_ns_prefix sync_box sync_box_guid sync_type debug
sync_visible_namespaces exclude_mailboxes send_mail_requests backup_send
backup_recv lock_timeouno_mail_sync no_backup_overwrite

remove_flags final_flags keywords_reset keyword_changes
Rguid uid
Mguid uid pop3_uidl pop3_order received_date stream
cname decision last_used
.
Hsyd2
The prompt hangs, when I push enter I get:
dsync-remote(syd1): Error: dsync(local): Remote dsync doesn't use compatible
protocol
Please can someone help me diagnose?
Cheers, D
