DDNS afraid.org

[meningitiscerebrospinalis]

hello guys,

i'm using afraid.org freedns services for DDNS with my own (sub)domain. until Asuswrt-Merlin 378.50 i used the sample wget script from afraid.org with cru and put it in /jffs/scripts/services-start

cru a afraid 1,6,11,16,21,26,31,36,41,46,51,56 * * * * sleep 6 ; wget -O - http://freedns.afraid.org/dynamic/update.php?your-private-key-goes-here

i'have already read
https://github.com/RMerl/asuswrt-merlin/wiki/Custom-DDNS

but i still dont't understand how it should work now. should i write a script with the title afraid.org and put it in scripts? then do what in the web-form (Advanced_ASUSDDNS_Content.asp)?

could someone please help me and take me by the hand through the process of setting up DDNS with afraid.org?

Asuswrt-Merlin 378.50 on my RT-AC66U

sorry. i think i've understood how it works now. so i'll reply to myself... maybe i can help someone else.

first i read:

https://github.com/RMerl/asuswrt-merlin/wiki/User-scripts

https://github.com/RMerl/asuswrt-merlin/wiki/Custom-DDNS

then i made a script called "ddns-start" in /jffs/scripts/
(nano /jffs/scripts/ddns-start)

inside i pasted


#!/bin/sh

wget -q http://freedns.afraid.org/dynamic/update.php?your-private-key-goes-here -O - >/dev/null

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


of course with my own private key (from afraid.org)

then paste
chmod a+rx /jffs/scripts/ddns-start

then i ran
./ddns-start

then i went to
https://192.168.1.1:443/Advanced_ASUSDDNS_Content.asp
and activated the ddns client. i wrote my own hostname (eg xyz.afraid.org) into the field "Hostname" ;-)

after hitting enter i got "registration sucessful"

happy.

I haven't looked into the new ddns script thing, but I have a similar setup. I use dnsomatic to update my domain at afraid.org.

Wait. wget from busybox can't work with https.

thank you for your reply, but i didnt use wget with https. i reached the settings-web-server with https. the wget command in the script runs on http (first i tried https but it failed ;-))

My mistake, sorry. As for me, I'm waiting Entware partition to be ready before updating dyndns:

# cat /jffs/scripts/ddns-start
#!/bin/sh

# Wait up to 15 seconds to make sure /opt partition is mounted
i=0
while [ $i -le 15 ]
do
    if [ -d /opt/tmp ]
    then
        break
    fi
    sleep 1
    i=`expr $i + 1`
done

/opt/bin/wget ...  > /dev/null 2>&1
if [ $? -eq 0 ];
then
    /sbin/ddns_custom_updated 1
    logger -t $(basename $0) "update successfull"
else
    /sbin/ddns_custom_updated 0
    logger -t $(basename $0) "update failed"
fi

BTW, I fixed the included curl binary so it should be able to work over SSL now. Might be worth looking at it as an alternative to wget.
