RSYNC With Username and Password

RSYNC With Username and Password

On Server2:

In this example we have user2 and password: PaSSWDUser2

yum install rsync

mkdir /home/user2/dir-server2

vi /home/user2/.rsyncd.secrets

user2:PaSSWDUser2

chmod 600 /home/user2/.rsyncd.secrets

vim /etc/rsyncd.conf

With content:

use chroot = false
lock file = /var/log/rsync.lock
log file = /var/log/rsyncd.log
pid file = /var/log/rsyncd.pid
[dir-server2]
        path=/home/user2/dir-server2/
        comment = Directory on Server2
        uid = root
        gid = root
        read only = no
        list = yes
        auth users = user2
        secrets file = /home/user2/.rsyncd.secrets
        max connections = 10

        hosts allow = 123.123.123.101

service iptables stop

rsync --daemon

On Server1:

In this example, we have user1 on server1 with password: PaSSWDUser1

Create a file name and store only the password of user2

vi /home/user1/.rsync.secrets

With content:

PaSSWDUser2

chmod 600 /home/user1/.rsync.secrets

chown user1:user1 /home/user1/.rsync.secrets

rsync -avz --password-file=/home/user1/.rsync.secrets /home/user1/dir-server1/ user2@123.123.123.102::dir-server2
