Note
This page lacks explanation and doesn't explain what the user can do with rsync. It needs revision to be useful.
Introduction
rsync is a program that synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction.
rsync can copy or display directory contents and copy files, optionally using compression and recursion.
This document is a rsync quick howto.
Installation
To install rsync do the following steps:
$ sudo apt-get install rsync xinetd
Configuration
1. Edit /etc/default/rsync to start rsync as daemon using xinetd.
$ sudo vim /etc/default/rsync RSYNC_ENABLE=inetd
2. Create /etc/xinetd.d/rsync to launch rsync via xinetd.
$ sudo vim /etc/xinetd.d/rsync
service rsync
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
2. Create /etc/rsyncd.conf configuration for rsync in daemon mode.
$ sudo vim /etc/rsyncd.conf max connections = 2 log file = /var/log/rsync.log timeout = 300 [share] comment = Public Share path = /home/share read only = no list = yes uid = nobody gid = nogroup auth users = user secrets file = /etc/rsyncd.secrets
3. Create /etc/rsyncd.secrets for user's password.
$ sudo vim /etc/rsyncd.secrets user:password
4. Start/Restart xinetd
$ sudo /etc/init.d/xinetd restart
Testing
Run the following command to check if everything is ok.
$ sudo rsync [email protected]::share Password: drwxr-xr-x 4096 2006/12/13 09:41:59 . drwxr-xr-x 4096 2006/11/23 18:00:03 folders
