CentOS

Found the problem, firewall settings on the server..

DNSmasq is running on the server and journalctl doesn't give me an error (I think)

A dnsmasq --test tells me the syntax is ok. So I assume it's some setting on the workstation I forgot. Anny ideas?

When I do netstat -tulnp I get the following result

So i recon it isn't listening? How can I add it? And I suppose I should add the 172.20.0.2?

I should have a tcp 0 172.20.0.2 in there right? How can i do that?

I've build a DNS server and a client using virtualbox Server has ip's 10.0.2.15 (NAT) and 172.20.0.2 (Intern) Client has ip 172.20.0.101 (intern) I'm trying to connect my client to my DNS server. I've changed the nameserver to 172.20.0.2 I thought that was it but it doenst seem to work. What Am i fo...

Yes, so run those again without --permanent or you need to reload firewalld or reboot. The --permanent flag adds the rule to the permanent list but doesn't affect the running rules. Did that but is still keeps saying that is't unable to resolve the host address When i try to access it through the i...

How did you open those?

sudo firewall-cmd --permanent --add-port=80/tcp

sudo firewall-cmd --permanent --add-port=443/tcp

Can you run these as root on your client: nmap 10.0.2.15 nmap www.linuxlab.lan Port 80 should be open. If not, check firewalls and that there's a web-server (apache?) running on your server. when trying to run "nmap 10.0.2.15" it says "bash: nmap: command not found" The I have ports 80 and 443 open...

Also The workstation gets its ip from DHCP so did i do that the right way?

I guess that Trevor ment this in /etc/hosts (oops, didn't see Trevor's post):

Code: Select all

10.0.2.15 www.linuxlab.lan www.linuxlab.lan  

Yes I can ping 10.0.2.15 I made the change but still can't get to www.linuxlab.lan

So i should remove the http://www.linuxlab.lan?

When i try curl www.linuxlab.lan in my workstation i get:
could not resolve host: www.linuxlab.lan; Name or service not know

I have no idea how i should fix it..
