I'm hosting a Mud and a website on a machine, Mud runs on port 4000 and the website on port 8000, since port 80 is blocked by ISP.

I can't figure out how to set up the DNS records so that I can access both on the same name:

http://www.my-mud.com
telnet www.my-mud.com 4000

I tried making an A-record for the www.my-mud.com point to the IP and then make an A-WebHop to point to http://www.my-mud.com:8000, but that didn't work.

Is there another type of record, e.g. SRV that I can use to send http traffic to port 8000? and other traffic to the default port?

Or will have to use two different names, e.g. mud.my-mud.com & www.my-mud.com?

/Thanks

You can't specify port numbers in any way through DNS. That is not part of its capabilities. You can use the same or different names for the 2 targets, but you have to include the port number, using whatever method is correct for the client looking to your server.

If for example, people use a browser to look at your site or play on your MUD, you would have to send them to 'http://my-mud.com:4000' or 'http://my-mud.com:8000', and if connecting by telnet, it has to be 'telnet my-mud.com 4000' or 'telnet my-mud.com 8000'.

You could try SRV records I believe, but not one browser in the world asks for SRV records.

If you want to get rid of the port number in the address, you can pull some redirect and proxy tricks, but DNS cannot do what you are looking for.

Thanks for the quick answer.

No problem. After a quick reread of what you wrote originally, you absolutely can run both on one name, and just tag the port on at the end. So your website will exist at http://my-mud.com:8000 and the mud (accessed through telnet) would be 'telnet my-mud.com 4000'.

If that doesn't work, something else is wrong.

DynDNS may be able to help you for the website. I think there is a web redirector options, it may require a premium...

But you should be able to redirect www.yourhostname.com to www.yourhostname:8000 and your users will be none the wiser.

There is no such service for telnet redirection. But you could configure your local machine to redirect port 22 to 4000 via iptables or squid or other ways.

DO NOT RUN YOUR MUD ON PORT 22! Doing so will require the engine to run as root. NEVER do this. Find some way for a 'stub' program to redirect packets to port 4000 from port 22.
