Hello.

There was an update to the DDNS and now the configuration for DUIA DNS does not work. I've tried with SSL on or off. Reset default configuration.

In-a-dyn version 2.9.1 -- Dynamic DNS update client.
Update forced for alias xxxxxxx.duia.us, new IP# XXXXXXXXXXXX
Temporary error in DDNS server response:
[500 Internal Server Error]


Will retry again in 600 sec ...

Same here, made update from r50595 to r50755 on N66U, WRT 1900ACS v2 and R7800.

My DDNS provider: no-ip.com

Username: theusername used for logging into no-ip website
password: the same password used the last years.

No changes made at all in the last months.

cat /var/log/messages |grep inadyn finds multiple lines where inadyn complains about bad auth.

Changed password on Website, inserted it into router --> still no change. Bad auth is given.

Had a look into nvram show |grep dns and looked for the stored credentials.
--> the password stored there is one character shorter than the one configured in webinterface?
For example password set to
12345678910abcdefghijklmnopqrstuvwxyzasdfasdfasdf
the last "f" is missing in nvram.

Changed the password on noip.com website according to this and rebooted routers
--> seems to work for now.

But why is the last character missing? Where did it go?


Will look deeper into this during the next days.

Thought it might help you @tiagocoelho2.

500 Internal Server Error is a generic message that indicates there is some issue with their service side crap, nothing specific or related to DD-WRT.

This is a GUI limitation.

Password maxlength="64"
btw 12345678910abcdefghijklmnopqrstuvwxyzasdfasdf works without problems because it is only 50 digits.

maybe think about if you really need passwords with more 64 digits.
passwords with special characters and 30 digits are strong enough

@ho1Aetoo your screenshots re: token/email so... this provider supports both email/token in the username field? If so it would be better to name the label Token/Email right?

As you can see from my 2 screenshots, there are even 2 working configuration possibilities.

Without more information, screenshots and your settings there is no help.

"does not work" is not an error description.

Edit: tested with build r50760
(but there were no duiadns specific changes)

OK current private test build DD-WRT 50784

duia 100% working, The UI was also simplified to remove invalid inputs,

No token needed despit duia says otherwise, this was maybe true for inadyn 1.96-ADV from 2005, in current inadyn 2.9.1 its not really a thing.

Setup with email was ignored anyway you could type any bullshit in there you wanted it went thru.

Just password and hostname and bingo.

@tiagocoelho2 now has no excuse. Marking as solved OK Tiago bugs-bunny 2 1/2?

Ty @ho1Aetoo Smile

It looks like my old password was too long.

Reduced the length and all problems observed after the update are gone now!

Funfact:
I used one of my two cats as random number generator a few years ago.
He jumped on the keyboard --> Random Password for old DDNS.

The new "not so random password" was done by me cleaning the keyboard Razz

password is 64 characters max. i think this is long enough. i assume you just need to learn how to handle copy & paste. the missing character at the end makes no sense to me
