rsync not working with latest kubuntu

Are you using a desktop OS? If so you can use grsync.

No I use rsync with a cron job to do automatic backups in the background. It doesn't run from the desktop.

https://www.digitalocean.com/community/articles/how-to-copy-files-with-rsync-over-ssh

Gives a few different commands.

Worth a try

Andrew,

This does not solve my problem, firstly I know how to use rsync with ssh, I've been using it for several years now and I know how to read the man pages, and secondly it is rsync that does not work, not ssh, when it used to previously. It even fails copying a local file to another directory on the same machine, without using ssh at all.

I uninstalled it and re-installed it and it still does not work.

Yes but at the bottom of the guide there are commands to use ssh with rsync. The first parts just show how to setup ssh but you can obviosly skip that part.

Did you try:

rsync -avz -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" --progress /file/to/send.txt servername:/path/to/dest/

Does that work?

No it doesn't work.

jjjacq@aldebaran:~$ rsync -avz -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" --progress /home/jjjacq/dates/*html sirius:/home/jjjacq/dates/
Warning: Permanently added 'sirius,192.168.1.2' (RSA) to the list of known hosts.
protocol version mismatch - is your shell clean?
(see the rsync man page for an explanation)
rsync error: protocol incompatibility (code 2) at compat.c(62)
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [sender=3.1.0]
jjjacq@aldebaran:

The thing is I have no problem with the keys, neither the host key (the machine hasn't changed) nor the public/private keys. I load the private ones in ssh-agent and from then on everything works without the need for passwords or passphrases.

ssh and scp both work perfectly.

I must however correct one statement I made earlier, I said rsync did not work on the same machine (from directory to directory). That's not correct. Within one machine it works.

So while I'm not sure what this means, my guess is the new rsync on Aldebaran is not compatible with "bash" on Sirius. This is kind of weird as why would the bash standard commands be modified. I'll read the manual to see if there is a switch to force rsync to use only the most basic subset of commands in bash.

Ok here is the workaround, apparently older version of rsync refuse to communicate with newer ones (it stops when the protocol number exceeds 30) . It refuses to communicate even though it can.

So the workarounds are:

1) update the old version to a newer one on the remote machine (preferred if possible)
2) lie about the protocol number using "rsync --protocol=30"

I've aliased rsync to"rsync --protocol=30" in my .bash_aliases file, just in case I forget :)
