nsupdate's Issues

USE_DRILL = YES means IPV6-Update everytime

Hello,

I've got an issue on IPV6-Updates. If the Option USE_DRILL is set to yes i get everytime NSLOOKUP=AAAA - so everytime my IPV6 gets updated:

So 9. Aug 19:10:03 CEST 2015 - _._.*** updated. Old IP: AAAA New IP: ::

When USE_DRILL = NO the IP doesn't need an update.

So 9. Aug 20:36:02 CEST 2015 - No update needed for _..**. Current IP: *::_

IPV4 works well with USE_DRILL = YES or NO.

I'm not sure if this really is a problem or if it should be like this. I'm so happy that i found that script - but actually i don't understand it 100% - and can't really create a patch. Sorry.

Greetings,
Jonathan

Getting the Domain-Record-ID via XML-RPC API

For convenience reasons it would be very nice especially for new user so they don't need to lookup HTML code elements.
I already did some tests, it took some time because there are no examples in the documentation for this case.

I think it is ready for implementation.
I don't know if the used XML-Parser is available on most systems. Maybe there are other options.

New dependency as an option would be:

xmllint (libxml2-utils)

You can try this:

#/usr/bin/env bash

INWX_USER="NiceUserName"
INWX_PASSWORD="VeryStrongPassword"
MAIN_DOMAIN="example.de"
DOMAIN="home.example.de"
TYPE="AAAA"

Sorry, somehow closed the Pull request instead of updating it

Three files changed. Checks where included and the IP Provider changed from http to https.

WAN_IP is not set

Hi,
I've encountered a strange bug. The WAN_IP is sometimes blank and then the script updates the DNS entry (which I presume doesn't work since it's blank). This only happens when I run the script. Running the curl command by hand works like a charm. It's bit strange. I might update the script in order that it fails whenever WAN_IP or NSLOOKUP is blank/not set.

Cheers,
scho

nsupdate doesn't work on systems without xmllint

Hi there

thanks for your great work.
I want to let you know, that the wan_ip is never set on systems without xmllint.
The wan_ip part is currently nested in the xmllint check, when you put it into a separate function i.e. get_wan_ip and call that one after get_domain_info everything works like charm.

Cheers

parse error. not well formed.

I got this error-message:

Is there a problem with the inwx-API or the script?

latest changes are missing after renaming master ->main

Hi @chrisb86 ,
as I can see the two latest commits (+2 merge) are missing.
I think it was done by the manual renaming of master -> main
Your local branch was not up to date so now some history is gone (not really I still have it on my fork https://github.com/EV21/nsupdate/commits/master ) - You can still fix it. - Just add my fork as remote, pull the changes and push it back to origin.

I think this should fix it:

git remote add ev21 [email protected]:EV21/nsupdate.git
git pull ev21 master
git push origin main

You could have waited for the release (announced to be released later in January) of the GitHub renaming tool. see https://github.com/github/renaming

Suggestion: Only update when IP changed

Hello,

it is possible that the domain record only get updated when the ip address since last check (could be checked with the logs) have changed?

Currently I'm running the script every 10 minute to be sure that when the ip address is changed the domain is updated. I don't know if thats for inwx.de okay. :)

IP check site change

The default IP check site is now only per https reachable. http://ip.dblx.io gives an 301 error.

parameter invalid

Hello,
I was just trying the script to update my INWX domain, but I get some error.

This is the output on CLI:

Starting nameserver update with config file ./nsupdate.d/www_example_org_AAAA.config (./nsupdate.sh.log)

This is from the log:

Mon Sep 27 14:33:21 UTC 2021 - www.example.org updated. Old IP: ::1 New IP: 
Mon Sep 27 14:33:22 UTC 2021 - No update needed for www.example.org. Current IP: 192.0.2.22

Any idea why the IPv6 is not updated?

Get external IP "locally"

Behind a router it's possible to get the external IP directly through upnp.
E.g. miniupnp ships with a neat script named external-ip which just returns the external IP without pinging some arbitrary online service.

Authentication error

since two days ddclient isnt working anymore. i searched the internet for an alternative and found this script. i configured everything like i should and got an "Authentication error" back when running the script. manually updating ip works fine so my login data should be correct. do i miss something?

Config File not Found

Hello,

when I try to run the script as a cron job, no config file is found. When I try to run it via ssh, everything works fine. A workaround for me was to write a script, which cd's into the folder of the script and then executes it.

Thanks a lot for your work on this script.

Best regards
Andreas

Edit: Another workaround is to disable the config file check.

Unable to retrieve WAN_IP

For some reason the script is unable to retrieve WAN_IP. The dependencies are all met. The script is running on a OpenWrt Chaos Calmer Router.

Is this a issue with https://ip.dblx.io? If so, are there any alternatives available?
