 Posted: Thu Nov 20, 2014 1:40 am Post subject: DYNDNS Updater on MEGA Webserver |
 |
|
I've followed with interest the postings by SIX1, PaulVK and MMarlette with their work on creating a WebServer.
I have a simple version up and working OK.
DynDNS.com is used to point to the WebServer IP address. On the webserver network, there is a computer running at all times with DynDNS Updater to change the dynamically-assigned IP address from the Internet Service Provider (ISP).
Has anyone been able to create the DynDNS Updater function and embedded it in the Mega/Xmega webserver?
If so, can you please describe the process?
(I will create my own code once I understand the process.)
Thanks.

I have NO-IP updater working under BASCOM.
The update process is usually documented on their site, pretty simple once the process is defined, no guess work.
Regards,
Mark |

Thanks Mark for your help.
Was able to find this method from the DynDNS website:
| Quote: | $ nsupdate -d
> server update.dyndns.com
> zone $ZONE
> key $KEY_NAME $KEY_HMAC
> update add $HOST.$ZONE 60 A 10.0.0.1
> send
> quit |
I have set up the TSIG variable names for my webserver (so the values for $VARS are all known).
What I don't understand is how to invoke these commands from within BASCOM in the WebServer code.
Any hints? |

I was a user of NO-IP that is why I went to their service when I wrote the BASCOM updater service for my apps.
I am sure there is such a page for DYNDNS but don't know ATM. Lots of projects to do today and have to clean office and workbench areas... 
I hope I can post a link here in reference to your issue. Mark I apologize in advance if it is not acceptable. Rather than posting the whole page content thought the link would be better.
http://www.noip.com/integrate/request
From your information you posted, you are a level or two to high in the commands as I see it. You need to talk GET/POST server commands/reponses directly to/from the dynamic name server.
Here is the comment section of my app. Sorry don't want to post the code due to this is just a small part of several huge projects. There is also link info in the comments. I did use FireFox's plugin and some visual basic to get it all working properly first. I was going to do a DYNDNS update client as well but got stuck in some other routines and zapped my free time.
hopefully this helps...this is fun stuff!!! Now off to clean....
| Code: |
Sub Server_WhatsMyIPpublic ()
'
' This routine will connect to the IP as defined in the strMyIPpublicserver
' (checkip.dyndns.org) from the server's configuration file and return the current
' Public address of the current connection.
'
' The MyIPpublic refresh rate is determined by lngMyIPpublicRefreshInterval as defined
' in the Server's configuration file. This request must be spaced
' at least 10 minutes apart to reduce server load.
'
' The server's response is limited to a string with a length of 16. Error checking
' of this response is done to ensure that a string boundary overwrite doesn't occur.
' Once the string is then obtained, the validity of the format of the IP returned is
' verified to make sure it contains three .'s. If the format is not valid, the response is
' blank or nothing and is returned to the caller and the error code of 254 is set.
'
' The timer ISR in Main.bas sets the flag bytMyIPpublicUpdate to trigger this event.
' In the event that the update from the server did not occur, the routine will reschedule
' the event based upon the value wrdMyIPpublicRetryInterval read from the server's
' configuration file. Only the events with an error code will be logged. Valid server responses
' are not written to the logfile.
'
' The following vars are read by the Server_CFGread routine :
' strMyIPpublicserver , lngMyIPpublicRefreshInterval , wrdMyIPpublicRetryInterval, booMyIPpublicenable
'
' Error codes logged to SD as follows:
' --------------------------------------------------------
' 255 = No connection obtained to server.
' 254 = Server's response failed validation
' 253 = No server response or timeout
'
' Reference Links:
'===========================
'MyIPpublic protocol is from : http://dyn.com/support/developers/checkip-tool/
' http://www.whatsmyip.us/imgcode.php which will give a reference to

'
'HTTP Header information obtained from : http://net.tutsplus.com/tutorials/other/http-headers-for-dummies/

'
' Send a request to the server :
' GET / HTTP/1.1
' Host: checkip.dyndns.org

'Install FireBug in to FireFox. This allows you to see the header requests(NET TAB), etc......

Thanks Mark, the No-IP method does seem much simpler.
I'll try to set my Dynamic DNS on No-IP and test it.
And, thanks for taking the time to help.
