Using ports in Bind9 (DNS) IPs?

Muscovy · 11-10-2009, 06:50 PM

Is it possible to make Bind point to a port?

Sorry, you'll need to clarify... what are you trying to do ?

I'm not very familiar with DNS. I know the generalistics of setup. I need to route the name to a specific port, not just the IP, because it's a non standard port.

No.. dns records do not support specifying ports ... only name <=> address

cheers

I need to operate out of port 82, not 80 (webserver). Is there any way I can get that working?

The web server plaintext protocol http defaults to port 80 but can be amended in Apache's httpd.conf.
Similarly for Apache SSL/443.
The DNS program bind only works on port 53.

Perhaps you can clarify which program/protocol you are on about.

The URL standard includes the port in it's definition...

Code:

[protocol]://[fqdn][:port]/[query_string]

eg.

Code:

http://www.linuxquestions.org:80/querystring

Most browsers will allow you to forget the port and they will try the default one for the protocol specified.

When running a webserver on a non-standard port you simply have to include the it when you give people the url.

You can run any daemon/service on a non-standard port but the client needs to be capable of specifying it

eg.

Code:

ssh username@myhost.mydomain.tld -p 2222

hope this helps
