@Brian – We don’t use the myip parameter. If we did, you could register send a dynamic IP update for any arbitrary IP of your choosing (once you verified the initial IP in your account). That would not be good, as it would give you control over DNS preferences for (potentially) someone else’s address. DynDNS is dynamic DNS, and we’re more dynamic IP monitoring. DynDNS can use the myip parameter since you wouldn’t want to point your domain to someone else’s IP and break your domain = different use case.

@Brian, I’ll have a colleague take a look.

I’ve modified a dyndns-compatible script for a special case — the update actually takes place from a third server and I use the myip parameter to specify the IP address, but this doesn’t seem to work with opendns, which seems to take the IP addr the request is coming from rather than that specified in the request.

My HWR54G Rev. M router supported DDNS by using a hardcoded list of DDNS providers, so I cannot use OpenDNS DDNS with it. But the list does include dyndns.org.

Thanks man, it works now…

I’m not sure I understood the added function provided by this software tool. I mean, in my job we use a Linksys BEFSR81 router which has built in support for DynDNS.org. Why, exactly, isn’t this built in support enough? (Yes, our IP is dynamic.)

I would like to have the option for .cm to .com typo correction enabled, but it is disabled by default and requires an account to be enabled. So, I’m a little confused here.

I have another problem with inadyn (i know i shouldn’t write here, but here it goes, anyway, since anton did it also )

[start inadyn log:]
INADYN: Started ‘INADYN version 1.97′ – dynamic DNS updater.
The request for IP server:
http://checkip.dyndns.org/
DYNDNS: IP server response: Current IP CheckCurrent IP Address: xxx.xxx.xx.xxx

W: DYNDNS: My IP address: xxx.xxx.xx.xxx
I:INADYN: IP address for alias ‘opendns’ needs update to ‘xxx.xxx.xx.xxx’
DYNDNS my Request:
https://updates.opendns.com/account/ddns.php?system=dyndns&hostname=opendns&myip
=xxx.xxx.xx.xxx&wildcard=ON&mx=opendns&backmx=NO&offline=NO
W:INADYN: Error validating DYNDNS svr answer. Check usr,pass,hostname!
W:INADYN: DYNDNS Server response:
nohost
[;end inadyn log]
What is going on – username and password are double-checked, only problem seems to be hostname, which is opendns. I am on a DDNS service by my ISP, and i don’t have my own hostname. What should i put there instead of opendns for this baby to start working? (i have tried this several times, even tried to put my dyndns hostname, but no luck, whatsoever.)

Anton, you can run inadyn manually on the command line with the –verbose 5 option to see the return code, ‘nochg’ or ‘good’ mean that it’s working properly.

Best,
Joe
