NethServer Version: 7.3.1611
I am currently preparing to upgrade my NethServer 6.9 install to NethServer 7.3 (using the rsync route).
The FQDN of my current install is very long (I am using the FQDN my ISP is using for my IP-address to make sure the reverse DNS for my SMTP-server is correct).
The FQDN uses this format:
When preparing the upgrade I have to use the same FQDN on both the old and the new server.
When applying the FQDN on the new server I get this error:
Fully qualified domain name
The host name part length must be up to 15 characters long
I have not tried the upgrade using a different fqdn yet (from the documentation I get the impression that doesn’t work anyway), how should I proceed?
