No connection with Linux client (2.0.34)

Hi,

Today I’ve installed Urbackup server and client on one server from one of my clients. This is the first time I have problems with urbackup server trying to detect the client installed in the same machine (name/host ‘patalibro’).

Urbackup srv log:

Both logs are in debug mode.

Server version: 2.0.36
Client version: 2.0.34
OS: Ubuntu 16.04.1 LTS

Any ideas?

Thanks in advance.

Are you saying you are running the client and server on the same physical machine?

Yes, Like the other servers I have (which includes one of my own, same OS version and I don’t have this problem. All the others servers which I’ve tested have Ubuntu 14.04).

But I can’t figure it out what is causing it. Already installed server and clients apps from scratch…

Thanks.

EDIT: also, I guess the problem is in this info on the server log:

2016-11-01 09:44:53: New Backupclient: patalibro
2016-11-01 09:44:53: Sending Identity to client “patalibro” failed. Retrying soon…

Have you tried to remove the client software from the client and then download the preconfigured client software from the server web interface?
This eliminates any typos / user confit errors.

The problem is that the clients is not being detected (problems with the
Identity, like the logs indicates it). I’ve tried to reinstall the client,
deleting the keys from server_key.txt (like tha faq points to it:
https://www.urbackup.org/faq.html#ident_err), located in
/usr/local/var/urbackup, but the problem still persist.

Any ideas?

Thanks.

Hi, any ideas about this problem?

Thanks in advance.

Well… I’ve just fixed… my Client left a old UrBackup server turned on on the same network and this was causing the problem.

Thanks.
