Problem with sync_client

[Avinash Sultanpur]

Hi,

I am in the process of setting up replication. I have setup the
replica server and I have tested it successfully with sync_test.

-sh-3.2$ synctest -u cyrus -w password -t "" replica
S: * STARTTLS
S: * OK imap2.mediassistindia.com Cyrus sync server v2.3.7-Invoca-RPM-2.3.7-2.el5
C: STARTTLS
S: OK Begin TLS negotiation now
verify error:num=18:self signed certificate
TLS connection established: TLSv1 with cipher AES256-SHA (256/256 bits)
S: * SASL PLAIN
S: * OK imap2.mediassistindia.com Cyrus sync server v2.3.7-Invoca-RPM-2.3.7-2.el5
C: AUTHENTICATE PLAIN ****
S: OK Success (tls protection)
Authenticated.
Security strength factor: 256

However, when I try to use sync_client to replicate a mailbox I get
the following error,

-sh-3.2$ /usr/lib/cyrus-imapd/sync_client -vl -u yukthi
Can not connect to server 'replica', retrying in 15 seconds

and this in syslog,

Aug 20 12:18:39 imap1 sync_client[10378]: connect(replica) failed: Invalid argument

I ran tcpdump on the replica server and I don't see any packets coming
to port 'csync'. You can also find the strace output of sync_client at
http://sultanpur.org/sync_client_strace.
