Hi,
after a crash I have to rebuild a new server for "opsi".
When it's done I try to restore my configuration with this command :
Code: Alles auswählen
opsi-backup restore --configuration --backends=mysql bropsi.201027.tar.bz2
but I obtain this message :
"WARNING: Your system config is different from the one recorded with this backup.
This means the backup was probably taken for another machine and restoring it might leave this opsi installation unusable."
How can I restore my backup ?
Best regards.

snippet from opsi-backup --help:
Code: Alles auswählen
restore <backup-archive> Restore data from <backup-archive>.
--backends <backend> Select a backend to restore or 'all' for all backends.
Can be given multiple times.
--configuration Restore opsi configuration.
-f, --force Ignore sanity checks and try to apply anyways. Use with caution!
So I'd guess you would want to use the --force parameter?

Hi,
I think that I have found the problem : when I have restored my configuration, the file /etc/opsi/opsiconfd.pem whas replaced...
So I had to regenerate it :
Code: Alles auswählen
openssl req -new -x509 -days 10000 -nodes -out opsiconfd.pem -keyout opsiconfd.pem
Now it seem's working but I can't access to "opsi-configed" on linux (that's work on Windows) !
The error message is :
"No connexion / javax.net.ssl.SSLHandshakeException: Received fatal alert: protocol_version"
I tried to reinstall "configed" with no more success.
Any idea ?
Best regards.

I would try to run opsi-setup --init-current-config after importing your configuration.
Configed might still not work, you may need to change some product properties, like fallback_tlsv1. It depends on your setup, and there are other topics where advice is given about connection problems with configed.
