Synchronet v3.16c-Win32 (install) has been released (Aug-2015).

DynDNS

This module is used in combination with the Synchronet Dynamic Domain Name System (DynDNS) Service hosted on Vertrauen to provide free .synchro.net hostnames to Synchronet sysops.

yourbbs.synchro.net

If you'd like a synchro.net hostname, I offer a free, very easy-to-use dynamic hostname service exclusively for Synchronet sysops. Your synchro.net hostname will always point to your current IP address, as long as your BBS is running. Using this service requires Synchronet v3.10 or later.

Directions

1. If you don't already have the exec/dyndns.js file, download the file into your Synchronet exec directory.

2. If you haven't already, create a QWK networking account on Vertrauen using your BBS's QWK-ID for the username (see this howto for more details).

Note: You do not have to actually join DOVE-Net to get a synchro.net hostname, if you do not wish.

3. If you don't already have one, setup a timed event (in SCFG→External Programs→Timed Events) to run the command-line ?dyndns yourpass periodically, where yourpass is the password you used when you created your QWK networking account on Vertrauen. “DYNDNS” is the suggested internal code to use for this event.

If you have a frequently changing IP address (and Synchronet v3.11 or later) set “Always Run After Init/Re-init” to “Yes”. With this option set to “Yes”, frequent timed updates should not be necessary.

If you have a static IP address, one run (update) per month should be sufficient.

:!: Make sure that “Enabled” is set to “Yes”.

4. After saving your changes in SCFG, and verifying that the Terminal Server has recycled, check the event log window or console output to verify that the “DYNDNS” event has executed. You can force the event to execute with the (Win32) SBBSCTRL:BBS→Force Timed Event menu option, or by “touching” (creating or modifying) the file data/dyndns.now.

5. Attempt to ping or connect to services at your-id.synchro.net, where your-id is your BBS's QWK-ID. It may take a few minutes for a new hostname to become active or for an existing hostname to resolve to a newly changed IP address.

You're ready to go with your new synchro.net hostname :!:

Options

-mx [hostname]

DNS MX (mail exchange) resource records are used to designate a specific hostname as the “mail exchange” (receiving SMTP server) for a specific hostname. If there is no MX record, then the hostname itself is assumed to perform the role of “mail exchange”. Some receiving SMTP servers now require that the *sending* SMTP server correspond to the MX record of the “from” hostname. If you want to specify an MX record for your hostname, you can do so by adding “-mx” (optionally followed by a hostname) to your “?dyndns” command-line (after the password). If no hostname is specified, then an MX record pointing back to your hostname will be created. Example: ?dyndns password -mx mail.someother.org

-hn <base_hostname>

If you want to update a hostname that is different than your BBS's QWK-ID, then you can specify that hostname (QWK-ID) on the “?dyndns” command-line (after the password) by using the “-hn” option followed by the hostname to use (not including “.synchro.net”). There must be a corresponding QWKnet account on Vertrauen for the specified hostname and password.

[ip_address]

If for some reason you want to specify a different IP address than the one that your BBS will be using to connect with Vertrauen, you can include that IP address on the “?dyndns” command-line (after the password). This is an advanced feature that you should not need to use under normal conditions, even if your BBS is behind a firewall/router using network address translation (NAT) - the DynDNS server running on Vertrauen uses your correct public IP address by default.
