How to use rsync with a different port?

Maintenance
1

Hi,
i am trying to figure out how to backup my box with rsync but with a different port.
i have tried to modify the backup.py[1], but that gives me this error when setting up rsync in the web interface:


I changed in line 19 [2] “-p 22” to “-p 2222”.

Any ideas on how to get it working?
Thanks for your time!

[2] “–rsync-options=-e “/usr/bin/ssh -oStrictHostKeyChecking=no -oBatchMode=yes -p 22 -i /root/.ssh/id_rsa_miab””,

This question has been asked but never answered. … see this thread for my solution to the problem which may or may not be practical for you.

Thank you for your answer!
I am already doing it like this. :slight_smile:
Maybe this should be more a feature request than a maintenance question. I think it choosing a port for the rsync backup can be useful for a lot of people who want to backup their Mail-in-a-Box to a home computer.

You can push the rsync output to your NAS easily. I am using at home the WD My Cloud Ex2 NAS and the SSH is listening on a different port than the 22. So AFTER opening the 2233 port at the firewall of my router, I’m doing this:

rsync -a -e “ssh -p 2233” /home/user-data/backups/encrypted/ root@xxx.xxx.xxx.xxx:/path/where/to/backup

Don’t forget the encryption key!

You may need to delete the local backup though after the transfer, but this might be a good example for a different cronjob entry.

hello,

i don’t know if this helps but you could just create a ssh config file for the root user on your miab.

/root/.ssh/config

Host hostnameof.your.bkpserver
    Port 2345

this way the rsync job will automatically use the desired port (no need to hack scripts).

Follow the instructions in your admin panel on the
System > Backup Status page
when you select rsync as the choice for where to backup to.

hello ColonelAjayAhlawat
you can try to change the backu.py
or just create a ssh file for rt user.
