Thanks alot for the prompt reply. Managed to get my ddns account unblocked.

Running it for 1 hour, i checked my logs as per below

It connected to the dyndns server 3 times. Will the logs display differently when IP is changed?

eureka!!

found the source of the problems! just to share incase other people have the same problem.

Inside /ffp/share/ezipupdate/ezipupdate.sh, there is a command to get current IP. The command is as per below
ip_command="echo `wget http://tilmanfrosch.de/ip.php -O $tmp_ip -q && cat $tmp_ip`"

I went to http://tilmanfrosch.de/ip.php to check my ip and ran the command multiple times to check, but it was'nt giving the correct IP address. This resulted in the multiple update. To resolve this problem, change the line to below
ip_command="echo `wget http://checkip.dyndns.com/ -O $tmp_ip -q && cat $tmp_ip| grep "IP Address" | sed -e 's/</ /g' | awk '{ print $11 }`"

Thx for the scripts SilentException

First off, thank you guys for such an awesome script.

My drive spins up every time the script is run.  Is there any
way to get it to cache, or relocate the tempfile to a non-disk location?
(usb? ?)

What I did in the meantime was to do a single run of ezupdate
when the box starts up, and to change the frequency to update
once a day at 11am. 

BTW, is there any way (logfile?) to know what is spinning up
the drives?

Thanks!

Hi Sinobato,

I had this problem. I don't really know what caused it because i am a noob. ^^ basically what happened is that the crontab $PATH does not have /ffp/bin inside.

What i did is i added the following statement in  /ffp/share/ezipupdate/ezipupdate.sh
PATH=/ffp/sbin:/ffp/bin:/usr/sbin:/sbin:/usr/bin:/bin

Do check your default path using root. Mine might differ from yours. ^^

Regards

Thanks linux_noob! I'll try this one later...

One last thing though, how about my other question:

Also, what should I put under the host variable? Should it be my dns-323's ip address? http://www.dyndns.com? or the host name that created on dyndns, say, foo.dnsalias.com?

This is regarding the ezipupdate.conf.

I having the same problem lately.Got blocked by Dns Server numberous times.Read all the above BUt still dont understand coz i noob in computer.
Is there a simpler way .Please help.
Thks

Do I still need the DDNS set to "Yes", if I have this custom install?

Just gonna talk to myself here and work thru it incase anyone else is having the same issue with funplug.

config file isn't being sourced, obviously. It comes defauled to rw for root. Don't know why SilentException has "#!/usr/local/bin/ez-ipupdate -c" at the top. Could be an issue.

Manually running:

/ffp/sbin/ezipupdate --address <MY.ACTUALL.IP.ADDRESS> --service-type dyndns --user <MYUSERNAME:MYPASSWORD> --host <MY.HOST.NAME> --interface egiga0 --max-interval 2419200 --cache-file /ffp/tmp/ez-ipupdate.cache

works. Definitely a perm issue (or something).

I've tried changing the top of the config file to "#!/usr/sbin/ez-ipupdate -c"... No effect.

For fear of getting banned again during the testing process, this will probably take me a couple days to sort out... ;-(

Could have sworn I chmoded 777 on the config file and it still didn't work. If I can't figure it out, I'll probably just rewrite /ffp/share/ezipupdate/ezipupdate.sh

Use the above code box command only retain the $ip_command functionality. That does work.

That or I'll just rewrite /ffp/start/ezipupdate.sh to do everything in one fell swoop. Dunno.

What a pain in the ass.

1.) I'm pissed at dlink for breaking functionality that worked perfectly fine in 1.04
a.) Especially pissed that nothing is being done about it after all this time.
2.) I'm really glad I'm using a product that's opensource... ;-)

If you want something done right, do it yourself I guess.

I adapted the script by linux_noob because the comparison did not work for me.
I've replaced "tmp_ip" with "cached_ip", added it to the log and made a comparison based on two IP in stead of comparing "$ip_command".
Also added add'l logging. All cache and logging will be moved to a USB stick in the next version (see also /ffp/etc/ezipupdate.conf file)
Next step is also Bacula backup server on DNS-323.

hi Guys

I have finally upgraded my ffp to ffp0.5~
I tried the above...and I still cant get it worked..

This is what I get from the ezipupdater.out file:

From the posts I read, it's because of the PATH thingy?
I did add that line in the script file though:
path : /ffp/sbin:/ffp/bin:/usr/sbin:/sbin:/usr/bin:/bin

Any clues? ?

hmm anyway, just to sum up.

I used SilentException script, then change the checkIP url to http://whatismyip.org/
finally got it work

I have FW 1.07 and am running the "stock" DDNS client, as configured from the admin web page.  It is working fine except that once in awhile it will send the local LAN address of the DNS-323 (192.168.0.2) to dyndns.com.  The crontab entry put in place by the stock firmware runs ddns-start every 10 minutes.  So, often it sends the correct external IP to dyndns.com on the next update, so the problem usually corrects itself within 10 minutes, but it is still annoying.

It does avoid updating dyndns.com when the IP does not change, which is good, and I am not getting banned.  But these momentary swings to the wrong address cannot be good and I'd like to fix it.

My first suspicion is that ddns-start is failing to get the correct IP address, probably by timing out when the response does not come back in time.  I don't know which site ddns-start uses to get the IP.  I think that if that site is slow to serve up the IP address, then that could be the problem.  I'm guessing that if ddns-start fails to get the IP address, it uses my LAN address 192.168.0.2 in the --address parm to ez-ipupdate and I am sunk.

Any thoughts?

I know about the ezipupdate script discussed in this thread.  But I am running optware and I am more likely to install ddclient as that is a popular and approved program for this purpose.

But are there any suggestions for solving this with the "stock" ddns-start/ez-ipupdate package?
