**sync_server**
***************

Server side of the synchronization (replication) engine


Synopsis
========

   **sync_server** [ **-C** *config-file* ] [ **-p** *ssf*]


Description
===========

**sync_server** is the server side of the replication system.  It runs
on the target (replica) system and listens for connections from
sync_client(8) which provides instructions for synchronizing the
replica system with the master system.

**sync_server** reads its configuration options out of the
imapd.conf(5) file unless specified otherwise by **-C**.


Options
=======

-C config-file

   Use the specified configuration file *config-file* rather than the
   default imapd.conf(5).

-p  ssf

   Tell **sync_server** that an external layer exists.  An SSF
   (security strength factor) of 1 means an integrity protection layer
   exists. Any higher SSF implies some form of privacy protection.


Examples
========

**sync_server** is commonly included in the SERVICES section of
cyrus.conf(5) like so:

   SERVICES {
       imap        cmd="imapd -U 30" listen="imap" prefork=0
       imaps       cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
       pop3        cmd="pop3d -U 30" listen="pop3" prefork=0
       pop3s       cmd="pop3d -s -U 30" listen="pop3s" prefork=0 maxchild=100
       lmtpunix    cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20
       sieve       cmd="timsieved" listen="sieve" prefork=0
       notify      cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
       httpd       cmd="httpd" listen=8080 prefork=1 maxchild=20
       **syncserver  cmd="sync_server" listen="csync"**
   }
