Hello,
I update dnsomatic using /usr/sbin/ez-ipupdate called with the following configuration file:

service-type=dnsomatic
user=youruser:yourpassword
interface=ppp0
host=yourhost

Pleasce change the configuration file with your right values

I call ez-ipupdate in wan-start but i also call it in a cru command because I noticed that sometimes the IP was not updated due to a quick modem disconnect and reconnect while the router was in "idle"

Hello
I am pleased that I was able to help you.
Ok ppp0 worked for me because i use a ppp connection to the public network, probably you use a cable connection

cru is the "equivalent of crontab" in asuswrt-merlin , please type cru in a ssh session to get help.
It allows you to run scheduled jobs.

==================
admin@RT-N66U:/tmp# cru

Cron Utility
add: cru a <unique id> <"min hour day month week command">
delete: cru d <unique id>
list: cru l

Hello Ocram,

I am very interested in howto use ez-ipupdate with wan-start.
I assume I just have to add the line /usr/sbin/ez-ipupdate within wan-start?
(Wan-start does already contain a script which send a mail when IP has changed).

I am a little bit confused with the configuration file.
ez-ipupdate --help tells me to use -c <file>
Should I just make a file (config) within /usr/sbin/ and then call ez-ipupdate -c config ?

Tx.

OK, Since dyndns.org is now exit for free users, a little contribution from my side in howto automatically update dnsomatic to prevent an account loss.

Ofcourse you need a dnsomatic account (www.dnsomatic.com) and a DDNS account (for instance noip.me). Make sure dnsomatic works.

Router setup:
Use putty.exe and logon to the router. (enable SSH in router -Administration -System)

I created a file called ez-ipupdate.conf in /jffs with content:

service-type=dnsomatic
user=[yourusername]:[yourpassword]
interface=eth0
host=all.dnsomatic.com

I then created a file called dnsomatic.sh in /jffs/scripts with content:

#!/bin/sh

# Called by init-start. Periodically updating DNS-O-Matic
# L. de Bles, 2014

/usr/sbin/ez-ipupdate -c /jffs/ez-ipupdate.conf

Another file called init-start in /jffs/scripts with content:

#!/bin/sh

# Periodically updating DNS-O-Matic.
# L. de Bles, 2014
#
# * * * * *  command to execute

# +------------------------- min (0 - 59)
#
# ------------------------------------------------------------------------------

cru a DNS-O-Matic "00 18 * * 0 /jffs/scripts/dnsomatic.sh"

Don't forget to make files executable:
chmod a+rx /jffs/scripts/* .

Just to check: run /jffs/scripts/init-start.
Check if updateschedule is set (crontab -l)

After rebooting dnsomatic is updated every sunday at 1800.

Just for fun: If you would like to auto update dnsomatic every time your WAN ip is changed, create or edit the file /jffs/scripts/wan-start

#!/bin/sh

# Auto updating DNS-O-Matic at WAN IP change.
# L. de Bles, 2014

sleep 5

/usr/sbin/ez-ipupdate -c /jffs/ez-ipupdate.conf

Make sure to make file executable (chmod a+rx /jffs/scripts/*)

Reboot your router to make changes effective.

Tip:
Edit a file with: vi /jffs/[filename]
Insert tekst by hitting "i" (insert)
Exit inserting by using [ESC]
Save file with: :wq
Exit file without saving: :q!

#!/bin/sh

wget -O- --read-timeout=0.0 --waitretry=5 --tries=400 --background http://freedns.afraid.org/dynamic/update.php?VVhTVF >/dev/null

but it does not work... any ideas why?

pleas help....

I just faced the same issue as freedns.afraid.org is not supported by Asuswrt-Merlin by default. But you can easily update it just by getting rid of some of the parameters which are not supported by busybox version of wget:

/jffs/scripts/wan-start:

#!/bin/sh
sleep 5
wget -q -T 1 -s [url]http://freedns.afraid.org/dynamic/update.php?VVhTVFblablablabla[/url] >& /dev/null

 

[mrvain]

A better version of the script to have status of Afraid DynDNS updates in the syslog:

/jffs/scripts/wan-start

#!/bin/sh

sleep 5

WGET_ERROR=$(wget -q -T 1 -O - http://freedns.afraid.org/dynamic/update.php?VVhTVFblablablabla | grep -v -i "has not changed" | grep -i error)

if [ -n "$WGET_ERROR" ] ; then
        logger "****** dyndns-afraid-update ******: DynDNS could not be updated: $WGET_ERROR"
else
        logger "****** dyndns-afraid-update ******: DynDNS update OK"
fi

Try this in "ddns-start"

#!/bin/sh

update=">key<"

/usr/sbin/curl --retry 3 -s -S "https://freedns.afraid.org/dynamic/update.php?$update" >/dev/null 2>&1 &


    if [ $? -eq 0 ]; then

     /sbin/ddns_custom_updated 1

    else

     /sbin/ddns_custom_updated 0
