csync is a file synchronizer especially designed for you, the normal user.
To be more precise csync is a client only bidirectional file synchronizer. You can use csync for different things. The intention is to provide Roaming Home Directories for Linux but you can use it to synchronize your music collection or create a backup of a directory.
csync is a library and ships commandline client by default.

This is the second and hopefully the last release candidate of csync 0.42.0.
csync is a bidirectional file synchronizer for Linux and allows to keep two
copies of files and directories in sync. It uses uses widly adopted protocols
like smb or sftp so that there is no need for a server component of csync. It
is a user-level program which means there is no need to be a superuser. With
pam_csync it is possible to create roaming home directories.
The first release candidate hasn’t been released to the public cause of a bug
in the state database. This has been fixed now. The userguide is available too.
Packages are available in the download section. Please report bugs to the bugtracker.
ChangeLog
NOTE: sftp is still really slow. This will be fixed with the next libssh version and I will release a new csync version which works with libssh 0.2.1.
10.28.08 - 04:48pm
This is the second beta release of csync 0.42.0. pam_csync is a PAM (Pluggable
Authentication Modules) module to provide roaming home directories for a
user session. This module is aimed at environments with central file servers a
user wishes to store his home directory. The Authentication Module verifies the
identity of a user and triggers a synchronization with the server on the first
login and the last logout.
There is a bug in several PAM applications calling the PAM functions on logout
in the wrong order. Take a look at:
gdm calls pam functions in the wrong order
http://bugzilla.gnome.org/show_bug.cgi?id=557794
OpenSSH calls pam functions in the wrong order on logout
https://bugzilla.mindrot.org/show_bug.cgi?id=1534
If you have ‘su’ (switch user) with pam support, check the patch
if it calls the functions in the right order.
You can find packages here.
NOTE: If you want to use csync with sftp. Compile the latest libssh version from svn and apply this patch to the csync source.

This version fixes several bugs to increase the stability of the file synchronizer. It provides a new plugin to synchronize two replicas with the sftp protocol. To get the csync sftp plugin working you need libssh 0.2 with the following two patches:
Map permission fields
Errno mapping

05.06.08 - 05:10pm
This is the first release of csync. It is just for testing purposes to collect some information. It doesn’t synchronize any data yet. Currently only the update detection and the creation of a journal is working. The intention is to get some testing and feedback about these processes. It does not change or copy any files. It is save to run it.
If you want to test csync:
csync -j /home/<user> /tmp
This will run the update detection and create the journal. You can enable some debug output if you edit ~/.csync/csync_log.conf and set csync.api to debug and csync.util to info. If you want to know that happens during the update detection set csync.updater to debug.
Run
csync /home/<user> /tmp

The source code of csync is now available via git [1]. This is a rewrite of the first version which is just the prototype of the file synchronizer. The current version is in an early state. Currently the function to init csync is being developed. The next steps on the TODO list are:
Currently most of the base has been implemented. The data structures for the collected file information will be stored in a red-black tree. For the journal a sqlite3 database will be used. The key to identify a file/path will be a 32bit jhash of the filename.
If you want to participate in the development, you should subscribe to the mailing lists [2] and take a look at the prototype [3]. The instruction how to compile csync and to work with the testing framework can be found in the trac system [4].
