csync - file synchonization

csync and pam_csync 0.42.0 beta1

GlaDiaC — Wed, 17 Sep 2008 13:11:55 +0000

This is the first beta release 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.

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

GlaDiaC — Thu, 03 Jul 2008 12:27:38 +0000

This is the first alpha 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.

csync 0.42.0 prealpha test version

GlaDiaC — Tue, 06 May 2008 15:10:35 +0000

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/ /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/ /tmp

Source: tar.gz | md5
RPM: openSUSE

csync source code is online

GlaDiaC — Thu, 28 Feb 2008 15:53:15 +0000

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:

Finish the journal functions
Load the configuration
Load the exclude list
Create a virtual IO layer for the plugin system, so that you can write plugins with libsmbclient or libssh.

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].

csync homepage goes online.

Last October I started writing my diploma thesis at SUSE Linux in Nuernberg. This is the homepage of csync a file synchronizer for Linux systems as a library. More information and content will follow.

There is no source code yet. I will setup git as soon as you can loose data using csync.
