DDNS - duckdns.org

[RMerlin]

Anyone for duckdns,org to work. I am running asus-rt n66u with 378.51.

I created ddns-start and have custom jffs scripts enabled. Ddns-start is updated by the logs just fine, but when I test it out not working. I have static the dns to opendns and went to opendns.com/welcome to test whether; it was using opendns or not. It was still using the opendns. Any help be appreciated. I tried the wan-start but that didnt work either.

This is my script:

<code>
#!/bin/sh
touch /tmp/000wanstarted
sleep 45
curl -k -s "https://www.duckdns.org/update?domains=domainname&token=XXXXXXX&ip="

if [ $? -eq 0 ]; then
/sbin/ddns_custom_updated 1
else
/sbin/ddns_custom_updated 0
fi
</code>

Your URL has an "ip" argument at the end but you don't provide any IP. Maybe that's causing the problem. Try appending the IP, contained in $1 (if using within a ddns-custom script).

I will try and add my IP at the end of the URL and see if that works when I get home from work. Thanks Merlin.

I tried putting my IP in from the previous script and still no luck. I played around and still cant figure it out. The code I tried using is below. I know the script us running since I see the 000wanstarted file. Any help please!

#!/bin/sh
touch /tmp/000wanstarted
sleep 30
curl -k -s "https://www.duckdns.org/update/ramen/261749d8-7c09-40a0-9eff-6c7d6c165822"

Hi,

I have just signed up and I have just bought an asus rt-ac87u.

I am interested as well in using ddns service of duckdns.

Looking at this wiki guide, at this guide on fritzbox and at the posts above, I hope that the following simple script will work:

#!/bin/sh
# Use duckdns.org service on your router
# First step: register on duckdns.org site and choose a subdomain name and note the generated token
# Second step: fill in the double quotes below the information needed
DOMAIN=""
TOKEN=""

/usr/sbin/curl --silent "https://www.duckdns.org/update?domains=$DOMAIN&token=$TOKEN&ip" > /dev/null 2>&1
if [ $? -eq 0 ];
then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi
exit 0

I have not tested this script yet as I have not configured the router neither, therefore your feedback would be really appreciated.

this worked for me

#!/bin/sh

curl -k "https://www.duckdns.org/update?domains=xxxxx&token=xxxxxx

if [ $? -eq 0 ]; then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi

fill in the xxx with your domain and token.
save this as ddns-start

Thanks hawke84, the script I have wrote above is quite similar to yours and should therefore work (still to be confirmed though, as I still need to configure the router).

this worked for me

#!/bin/sh

curl -k "https://www.duckdns.org/update?domains=xxxxx&token=xxxxxx

if [ $? -eq 0 ]; then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi

I have a slight variant of that working where it captures and tests the response from DuckDNS. Otherwise I found that the script always signaled a success, even if the update hadn't occurred:

#!/bin/sh

result=$(curl -k --url "https://www.duckdns.org/update?domains=<DOMAIN>&token=<TOKEN>&ip=")

if [[ $result == "OK" ]]; then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi

@RMerlin how would i go about incorporating duckdns into your script https://github.com/RMerl/asuswrt-merlin.ng/wiki/Custom-DDNS
Using a DDNS with VPN

below is the current working script

#!/bin/sh

# register a subdomain at https://www.duckdns.org/ to get your token
SUBDOMAIN="xxxxxxxxxxx.duckdns.org"  *xxxxxx = removed for security*
TOKEN="xxxxxxxxxxxxxxxxxx"   *xxxxxx = removed for security*

# no modification below needed
curl --silent "https://www.duckdns.org/update?domains=$SUBDOMAIN&token=$TOKEN&ip=$1" >/dev/null 2>&1
if [ $? -eq 0 ];
then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi

Please can you help as you're the master at these things?

Thanks

I haven't tried this myself, but I think should just be able to copy your script into /jffs/scripts and rename it to ddns_start.

Make sure you set the DDNS page to "Custom" and ensure you enable JFFS scripts on Admin/System page:

Let us know how that works.

Thanks for trying to help me

Funnily enough that's how i did it, created script on router, made sure properties were correct and turned on custom_ddns and added hostname etc it registers sucessfully .....what i would like to know is how i link ddns to a vpn

@RMerlin can you provide some magic scripting please if it is doable?

 

[Dabombber]

Did you try the VPN example? You might need to change the tun11 lines if you're using a different client instance.

Spoiler: /jffs/scripts/openvpn-event

#!/bin/sh

if [ "$script_type" = "up" ] && [ "$vpn_interface" = "tun11" ]; then
    # OpenVPN tunnel won't open until openvpn-event script is finished, run the rest in a background shell
    (
        # Loop until VPN tunnel is established or the timeout limit is reached
        COUNTER=0
        LIMIT=10
        while [ "$COUNTER" -le "$LIMIT" ] && ! ifconfig | grep -Fq "tun11"; do
            sleep 1
            COUNTER=$((COUNTER + 1))
        done

        SUBDOMAIN="xxxxxxxxxxx.duckdns.org"
        TOKEN="xxxxxxxxxxxxxxxxxx"

        curl -fs -o /dev/null "https://www.duckdns.org/update?domains=$SUBDOMAIN&token=$TOKEN"
    ) &
fi

Thanks, bomber looks like just what i was needing quick question would workout what tunnel is in use, like a list?

 

[Dabombber]

The ifconfig command should show which tunnel you're using.
