About install internal network

[nanoziobelo]

Hi
I want try to install to use it on internal network class192.168.0.1/24 without external connection is possible?

[dinger1986]

Yes but you still need to use an internet resolvable domain name, you don't need to open ports

[nanoziobelo]

I see installer ask internet connection and from mai lan cant access to internet.
To dns I can make internal dns server. but cant solve to get info from internet.

[dinger1986]

It does need an outgoing connection to verify the ssl certificates using certbot and internet resolvable dns (a real domain).

[dinger1986]

Alternatively you can get the ssl certificates from elsewhere and have them in in place, comment out certbot commands etc, but it needs to have internet to download packages etc

Is possible to make this:
1 creata machine with internet access with lan 192..... and install al system
2 clone disk on other machine and change ip 192.... to my internal network 10...... ? or in case chenge the ip of install machine in 10....?

[dinger1986]

Yea of course, just change your dns

I try to remake a clean debia install machine edit the hosts file like
192.168.1.103 WEBRRM.localhost WEBRRM api.WEBRRM.localhost rmm.WEBRRM.localhost mesh.WEBRRM.localhost

get this error

The server will not issue certificates for the identifier :: Error creating new order :: Cannot issue for "*.webrrm.localhost": Domain name does not end with a valid public suffix (TLD)
think problem on generate certificate I can force to skip?
