NethServer & Redirections to LOCAL

Support
1

Hi all,

My goal is to install Jitsi, Mattermost/add-onJitsi and Matrix/with-a-link-to-Jitsi on three VMs connected to the NS gateway server.

I only have one real LOCAL domain which is toto.org, so I created subdomains at the registrar: jitsi.toto.org and mattermost.toto.org along with CNAMEs: www.jitsi.toto.org, mail.jitsi.toto.org, etc … as well as www.mattermost.toto.org, mail.mattermost.toto.org, etc …

Question:
(Presently I am trying only with jitsi.toto.org.)
● For the redirection, is it enough to create a DNS entry in the NS gateway server for each of the domains (jitsi.toto.org, mattermost.toto.org, and toto.org along with their IP addresses) or do you have to create redirections for all of the “CNAME.domain.tld” with the Reverse Proxy, which will create entries in Server Alias?

● What to do with the FQDN (server.domain.tld) - create a redirection with the the Reverse Proxy or just directly create a Server Alias for each of them ?

The problem is that yesterday I created redirections for each of the CNAMEs including jitsi.toto.org (which created Server Aliases entries for each them).
It didn’t work even after restarting httpd on the VM server and on the NS gateway server, clearing the DNS cache and the browser cache on the workstation.

I deleted the redirection for jitsi.toto.org and its alias. I created a DNS entry for jitsi.toto.org.
It didn’t work even after restarting httpd on the VM server and on the NS gateway server, clearing the DNS cache and the browser cache on the workstation.

I left everything like it was and closed the VM. Tomorrow is another day !

This morning I restarted the VM and it worked !

Any suggestion will be welcome,

Michel-André

DNS needs time to be replicated maybe

@m.traeumner @stephdl,

Thank you for your replies.

A day before my first post, I asked for a Let’s Encrypt certificate and it worked. So the DNS should be OK.

For now, on the Gateway to internet server:

  • I created an entry for DNS → Hosts: jitsi.toto.org with the “Wildcard DNS record” checked and pointing to 192.168.1.108.
  • In Reverse proxy → Virtual hosts, I created entries for jitsi.toto.org and all CNAMEs, all pointing to 192.168.1.108, which created entries for all CNAMEs in DNS → Alias except for jitsi.toto.org as it is already in DNS → Hosts.

All seems to work correctly.

The only “funny” think I found is from another portable, after clearing the caches of the OS and the browser, the first time I access https://jitsi.toto.org:8443, I get the default NethServer web page. If I refresh the page, then the Jitsi welcome page is now displayed.

It was because I had a second router address DNS server in network config for that station that was pointing to an no more existing LOCAL server.
