[webmin-l] Issues when installing Webmin 1.831

Hi,



I successfully install the latest webmin 1.831 on a RedHat Entreprise Linux server.

I added my second server in Webmin Server Index then I added it in the cluster section in the bind dns server.

I also added the ip on my second host in the appropriate place... (I think)



I started to create master zones and A records.



I have 2 issues.

1. My hosts are not sync to my second host.

2. If I nslookup my master server, I don't get any answer... Only a timeout.

There is no iptables or firewalld services.



bind-9.9.4-38.el7_3.3.x86_64 is installed.



# nmap 127.0.0.1

Starting Nmap 6.40 ( http://nmap.org ) at 2017-05-04 16:10 EDT

Nmap scan report for localhost (127.0.0.1)

Host is up (0.0000090s latency).

Not shown: 997 closed ports

PORT STATE SERVICE

22/tcp open ssh

111/tcp open rpcbind

10000/tcp open snet-sensor-mgmt

Nmap done: 1 IP address (1 host up) scanned in 0.12 seconds



I will appreciate if someone can give me a hint.



Thanks in advance.

Start here:

Is named running? You should see port 53 answering for Bind

If it's running you need to find out why NMAP is not showing that port open

The latest version of Bind needs to have the master server listed in
each zone and not globally on your slave server.

It says it's running now. Your connection refused is likely a
firewall. 172.22.2.50 is blocking port # 53 run nmap on 172.22.2.50
and see what ports are open.
