Error "Server Not Found" - Virtualmin Fresh Install

Help! (Home for newbies)
1

Hi, I’m new with Virtualmin, I just installed the GPL version of Virtualmin on an Ubuntu16.04.01 LTS server.

I can access the panel without any problems and I can create a virtual server both from the Virtualmin Tab > Create Virtual Server and the Webmin Servers > Apache Webservers > Create Virtual Host tab. And I followed the instructions from Virtualmin’s video tutorial on YouTube, and it seems everything was ok, but when I go to my domain (my site.com) I just get a “Server not found” error. But when I use the “preview website” option in virtualmin I can see the site. It’s really weird.

Also, I did upload a fresh install of Wordpress in the /home/myfolder/public_html/ document root directory

I checked my DNS settings on IntoDNS.com and got the following Errors below:

Error Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records.
Error DNS servers responded ERROR: One or more of your nameservers did not respond:
The ones that did not respond are:
my.ip.address

Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. * ( I have two nameservers setup, so I don’t understand that)

Missing nameservers reported by your nameservers You should already know that your NS records at your nameservers are missing, so here it is again:

ns2.mysite.com.
ns1.mysite.com.

SOA Error SOA record No valid SOA record came back!

MX Error MX Records Oh well, I did not detect any MX records so you probably don’t have any and if you know you should have then they may be missing at your nameservers!

WWW Error WWW A Record ERROR: I could not get any A records for www.mysite.com!

(I only do a cache request, if you recently added a WWW A record, it might not show up here.)

Any help?

Thanks

Howdy,

It sounds like your issue is DNS related. It may be that BIND isn’t listening for requests, or there may be a firewall blocking access to BIND.

What is the output of these commands:

netstat -an | grep :53 iptables -L -n

Hey thanks for the reply…

The first command returned this:

the second this:

Howdy,

It looks like BIND is up and running, and listening on all interfaces.

What stands out to me, is that there’s a firewall there with quite a few rules in it.

It’s hard to follow exactly, but I have a hunch that the firewall may be the culprit in preventing access to BIND/DNS.

It looks like you have UFW installed there for handling firewall duties – could you temporarily disable UFW, and any remaining firewall rules, then try again?

If it works at that point, then it just means you need to tweak your firewall settings.

Okay I disabled the firewall and it’s now pulling up the domain but now the usual wordpress install page isn’t showing, it’s just showing this:

<?php /** * Front to the WordPress application. This file doesn't do anything, but loads * wp-blog-header.php which does and tells WordPress to load the theme. * * @package WordPress */ /** * Tells WordPress to load the WordPress theme and output it. * * @var bool */ define('WP_USE_THEMES', true); /** Loads the WordPress Environment and Template */ require( dirname( __FILE__ ) . '/wp-blog-header.php' ); Also I need a firewall, so is there any particular ports that I need to keep open. This is what I had open before disabling it. Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip To Action From -- ------ ---- 22 ALLOW IN Anywhere 80/tcp ALLOW IN Anywhere 443/tcp ALLOW IN Anywhere 25/tcp ALLOW IN Anywhere 80,443/tcp (Apache Full) ALLOW IN Anywhere 10000 ALLOW IN Anywhere 22 (v6) ALLOW IN Anywhere (v6) 80/tcp (v6) ALLOW IN Anywhere (v6) 443/tcp (v6) ALLOW IN Anywhere (v6) 25/tcp (v6) ALLOW IN Anywhere (v6) 80,443/tcp (Apache Full (v6)) ALLOW IN Anywhere (v6) 10000 (v6) ALLOW IN Anywhere (v6) Also not sure if this means anything but before i disabled it, I did this command listed below, from a search on youtube and it showed this: sudo grep -i ' virtualhost' /etc/apache2/sites-enabled/*.conf VirtualHost *:80 Then when I disabled it, it showed this: sudo grep -i ' virtualhost' /etc/apache2/sites-enabled/*.conf VirtualHost 162.243.164.137:80 Also did command netstat -ln |grep 10000 tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN udp 0 0 0.0.0.0:10000 0.0.0.0:* And before disable, when I did an NS Lookup command, it showed this sudo nslookup www.mysite.com ;; Got SERVFAIL reply from 2001:4860:4860::8844, trying next server ;; Got SERVFAIL reply from 2001:4860:4860::8888, trying next server Server: 8.8.8.8 Address: 8.8.8.8#53 ** server can't find www.mysite.com: SERVFAIL Then after disabling the firewall it showed results but I don't know what server and address this is. sudo nslookup www.mysite.com Server: 2001:4860:4860::8844 Address: 2001:4860:4860::8844#53 Non-authoritative answer: Name: www.mysite.com Address: 162.243.164.137 Thanks

It’s simplest to tackle one issue at a time, so let’s go over the Wordpress issue you described there –

It looks like it’s just displaying the PHP code, rather than executing it, is that correct?

What’s the output of this command:

dpkg -l ‘php*’

Also, if you go into System Settings -> Re-Check Config, does it detect any problems?
