Hi! I have tried to get Cyrus replication working without success. It is RHEL 5.3 with standard cyrus-imap 2.3.7-2. Synctest with -t "" succeeds, but sync_client -v -r gives "retrying in 15 seconds". Tcpdump shows that there is traffic in both cases. Any help is appreciated. sync_ lines in imapd.conf on imapmaster host: *** sync_host: imapreplica.company.com sync_authname: cyrus sync_passwd: protected *** The following does not work: *** cyrus@imapmaster$ /usr/lib/cyrus-imapd/sync_client -v -r Can not connect to server 'imapreplica.company.com', retrying in 15 seconds *** The following works: *** cyrus@imapmaster$ synctest imapreplica.company.com -t "" S: * STARTTLS S: * OK imapreplica.company.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 LOGIN PLAIN S: * OK imapreplica.company.com Cyrus sync server v2.3.7-Invoca-RPM-2.3.7-2.el5 C: AUTHENTICATE LOGIN S: + VXNlcm5hbWU6 Please enter your password: C: <protected> S: + <protected> C: <protected> S: OK Success (tls protection) Authenticated.
