rsync, rsyncd and ssh


Hello,

I user rsync for synching two servers and works fine but I'm not familar with rsyncd and rsyncd.conf files.

1)What should I learn about these two ? as  daemon and the configuration file?

2)What happens if one of the two servers I user for rsync doesn't have rsync installed.Let's say I send files from machine A to machine B. My rsync is on A. Do I need a rsync on machine B as well?

3)What happens if I don't have ssh on machine B? can I still transfer my files to machine B?

4)When do I have to user rsyncd.conf file?

Thanks

1.  read through the man page of rsyncd.conf

rsyncd.conf is more like a smb.conf file where you specify the shares on a machine.  you can use the chroot = yes option to contain the users from seeing only those specific directories for share.

this is when you do not have a SSH access to the remote machine FROM which you want to copy.  it opens up port 873 and listens as a daemon for incoming connections and makes available all shares specified in rsyncd.conf

2.  you can specify the direcotires that you want to share for syncing with some other system.  the rsyncd.conf file should be created in the FROM machine when you are copying files.

the TO machine needs to have only the rsync command run to get the directories from the other machine.

3.  see answer 1

4.  when you want only specific directories that are to be shared for syncing and do not want to enable ssh and feel that the user should not see other files on the system, then you can specify the rsyncd.conf
