DNS Servers


My company had an outside company configure DNS Servers for websites we host. Our instructions were to have them configure with the least amount of services running and with Iptables. I am new to Linux but I am able to adminster the DNS Servers. The DNS Servers are running on Redhat 9. I will like to know how can I find out if thier implentation of these servers went according our instructions. In other words I will like to verify their setup. Does anyone have like a template of what services shouldn't be running if you are using the box as just a outside DNS Server on REdhat 9? I will also like help finding out which account they have created. The Server is running on in text mode.

Thanks
D

The quickest way to determine what network services are running is to type 'netstat -tul' - I would expect to see ssh, 'domain' for DNS, ntp, and smtp.

You can see the active IPTables rules by typing:

/sbin/iptables -L

When I run that command this is what I get:




Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 *:10000 *:* LISTEN
tcp 0 0 dns1.iqinternet.:domain *:* LISTEN
tcp 0 0 dns1.iqinternet.:domain *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 dns1.iqinternet.co:rndc *:* LISTEN
udp 0 0 *:32768 *:*
udp 0 0 *:10000 *:*
udp 0 0 dns1.iqinternet.:domain *:*
udp 0 0 dns1.iqinternet.:domain *:*
udp 0 0 *:724 *:*

Is this is what I'm suppose to see?

Thanks

http://www.webmin.com

Handy little tool I use to administer my text only server at home. It has all the necessary helper pages for total system administration. And it runs in a web browser.

'domain' is DNS, as is 'rndc'. 'ssh' is obvious.

As dfctve_end_user says, Webmin is a top piece of software for admining UNIX servers. It's default port is 10000, so that probably explains those listings.

I don't know what is running on UDP port 724 - that isn't an officially registered port number. Try Google or:

netstat -tulp

The first column lists the actual name of the program using the port.
