Topic: Port 53 in Server only mode ...

[dexter]

Hello guys !

My SME is in SERVER-ONLY mode !!! Monowall is used for connection...

I've installed VMWARE server on my SME 7.1.3. Works OK, but ...

I've installed W2K3 server as VM with WEB, SMTP,POP3 and DNS server. I actualy convert one working physical machine to virtual.

All services running well, but I have problems with port 53 which is BLOCKED by default, so my DNS is not resolved at all.

How can I check If I am right and there is port blocking problem and If, how to open a port 53. WWW on port 80 works fine !!!

Can anybody help with some directions or knows solution ?!

Regards,

Yup, ask in a MONOWALL forum since you use it as your gateway.

Your virtual windows server should have a different IP address than the SME server.  Unless your VM is using the VMWare 'shared IP' mode there's no way for SME to block traffic to it.

If you *are* using 'shared IP' mode, you'll have to play with port forwarding on the SME -- and may be unable to do this (that is, you may run into unexpected problems) since DNS is one of the core SME services.

At the simplest, 'telnet <ip> 53' should connect to an IP with a listening DNS server.  You won't get much feedback, but you won't get a message saying 'Could not open connection to host'.

Or, do some DNS lookups and specify the IP to use for the lookups, like this: 'nslookup google.com <dns.svr.ip>' (for example: 'nslookup google.com 4.2.2.1').

Also, you may want to obtain a copy of nmap in order to test for open ports...

Telnet won't work as DNS using UDP 53

Absolutely correct; thanks for the correction.

[feeble attempt to justify earlier post]
SME 7.0, SME 7.1.3, Windows NT 4 & Windows 2003 all also listen on TCP port 53, so, while knowing that the server accepts a connection on TCP port 53 may not be helpful if your firewall is still blocking UDP traffic on port 53 at least you can verify that some service is actually running on the target host...[/feeble attempt to justify earlier post]

Tx, guys for effort you made.

VMWARE server works fine and there is no port blocking as I was thinking. Problem was in P2V conversion !!! I am using a new image and everything works fine

If somebody needs step by step guide to install VMWARE server on SME 7.1.3 let me know.
