Server 1.4.7 Client 1.4.8 wont discover

I have a 1.4.7 server running on Debian. I have several clients running 1.4.7. Now i have a new Centos based client and the only version i can get there is 1.4.8 and that one is unable to discover the backup server on the local network. I can ping the server but urbackup does not find it.

Any advice would be appreciated.

Why don’t you upgrade the server to 1.4.8?

Because if it fails to work with the clients i have i have to upgrade all my clients and check everything.

So more in the sense of do not touch a running system. And i never read anywhere it was not possible thats why i ask.

If it is expected not to work. Ill upgrade most likely. But if its unexpected i fear for more problems.

I can’t speak for certain, but it is typical in software to preserve backward compatibility from client to server. Going the other way can be nearly impossible though if you make any changes.

To make a server version that is compatible with prior versions of software only requires a graceful degradation of features for anything that you have added. To make a server version compatible with future versions of the client would require telepathy.

@uroni would have to confirm, but that would be my assumption of what is going on here. I have successfully run server 1.4.8 with client 1.4.7 as it took a while for them all to self-upgrade. I have never tried it the other way around.

But, have you tried a download from here: http://sourceforge.net/projects/urbackup/files/Client/1.4.7/

Usually it is comptabible both ways, but it is of course difficult to test. And there were only bugfix changes between 1.4.7 and 1.4.8.

I would guess you have unrelated problems with your client such as a firewall misconfiguration.

Ur right i killed the firewall and i was able to connect. (shame on me, i should have tested that) Somehow somebody decided to install a new server in a different way from the old once. Thanks for the response.
