You can't specify a port. If your webserver is listening on port 81, users need to know that, and URLs pointing to your server need to include that specifier.

Valid options:

usage: ?dyndns <password> [ip_address] [-mx address]

Most people don't need to specify ip_address, but that depends on your setup.

You might look at setting up a reverse proxy with hostname-based forwarding; it listens on 80, 443, whatever, and your other servers are behind it listening on other ports that end-users don't need to know about.

host alleycat.synchro.net says the associated ip is 24.138.28.115. Is that your IP? If so Synchronet's DYNDNS is doing what it should do.

Let me point out my specific question "Synchronet's DYNDNS to point to a specific port?"

so here is the scenario, my port forwarding is setup, I have several servers running ... so the question is "is they a way for Synchronet's DYNDNS to point to a specific port?" if not then the answer is "no, you'd need to setup a name server behind your router!"

If you just go to http://alleycat.synchro.net you'll get port 80 which is my commercial website(asmf-etrucker.com). if you go to http://alleycat.synchro.net:81 you'll get Twisted Truckers BBS (if the Raspberry
Pi is running). if you go to emptykeg.synchro.net you will again get (asmf-etrucker.com port 80) if you go to http://emptykeg.synchro.net:82 or http://asmf-etrucker.com:82 or alleycat.synchro.net:82, etc, you will
get Empty Keg ... see my question?

Let me point out my specific question "Synchronet's DYNDNS to point to a specific port?"

DNS is about mapping hostnames to IP addresses, and doesn't concern itself with specific services (with the mild sort-of exception of MX records) or port assignments. So this really isn't a thing you can do.

DNS also isn't web-centric, so if it let you advertise which port on which host was used for HTTP(S), it's hard to say where that would end. Would a record include mappings for port assignments for all manner of services?

so here is the scenario, my port forwarding is setup, I have several servers running ... so the question is "is they a way for Synchronet's DYNDNS to point to a specific port?" if not then the answer is "no, you'd need to setup a name server behind your router!"

What you might want to do is set up a reverse proxy. I use nginx for this. There are others. The proxy accepts all HTTP(S) connections from outside, then forwards to a specific host and port on your internal network based on the hostname in the request. (This can be done with HTTP more so than other services, because the hostname is included in the request header.)

A full scale making would be too copiOus to maintain, I agree, my domain is setup with DynDNS which allows me to setup subdomains, ie alleycat.asmf-etrucker.com port 81, that doesn't not facilitate alleycat.synchro.net on port 81. I was kinda hoping that DM's DNS might be able to include a ipaddress:xx because I am too lazy these days to take the time and setup ip-tables/routing tables etc on my slackbox :P

I am currently only thinking of http(s) at this point, not needing telnet, ssh, smtp, etc so I can simply use apache's vhost with a redirect.

Let me point out my specific question "Synchronet's DYNDNS to point to a specific port?"

DNS doesn't contain port information (at least, not for Telnet and the services you're using). So... to restate your question: Can (any) DNS point to a specific (telnet/http/ftp/etc.) port? The answer is no.

Get a cheap VPS and use iptables rules to redirect the port. It may induce a little lag but if you can find something close (network topology speaking)
it may not make much difference.

what are you trying to do with it? AFAIK, it is only for updating your synchro.net IP when it changes... is it not an inbound service... there should need be no changes to it since it only connects to digital man's main system...

I'm jumping in here late, didn't see the original email, but was thinking that since Synchronet does virtual hosts, if you own those domains and point them to the same IP, Synchronet could serve content for the specific host in question.

Or did you want port 80 traffic on one host name to go to one system and port 81 on that same host to another system on your network?

I think you're confusing http redirection with DNS. There's nothing in DNS that allows a "redirect" to a specific TCP port number on a host. What you're asking for is not a feature of *any* dynamic DNS service.

Exactly this, however a probable source of confusion:

you're asking for is not a feature of *any* dynamic DNS service.

HTTP redirection (and "stealth redirection", likely proxying) seems to be an added feature offered by various dyndns providers. Maybe this creates the illusion that it's a DNS thing, or breeds assumption that it can be expected of a dynamic DNS service.

Wouldn't be difficult to achieve if it was wanted. Not sure how much traffic it would generate, though.

Not *confusion*, semantics, as I did say *WEBHOP* which has long had the underlying definition of 'http redirect', I just need to phrase my questions more precisely so as not to confuse the readers :P I don't recall asking about a routing table for telnet, ftp, ssh etc, just asked if SBBS had the port option :-P the quick fix for me was a couple of simple vhost entries in my apache web server

No offense intended. Your first few messages on the topic said nothing about "webhop" and asked only about using some kind of service-port mapping with DNS. I didn't make the leap to non-DNS value-adds offered by dyndns providers. So yes, phrasing.

recall asking about a routing table for telnet, ftp, ssh etc, just asked

Indeed you didn't. I only wanted to point out that if DNS did what you were asking, HTTP isn't special and the concept ought to extend to other services.

Re: "confusion", I meant that if HTTP redirect is commonly offered by DNS providers, people might assume that *any* dynamic DNS provider offers it, and that since it's coupled with their DNS service they may not realize that it isn't a DNS thing. This was said after "webhop" was brought up.

I suspect this may come across as argumentative and that's not my intention; just hoping to clarify.
