Dynamic dns updates 127.0.0.1 to server

[traidua]

Hi all,

I have a small issue with dynamic DNS service. At least one a day, my router updates 127.0.0.1 to my no-ip server instead of the router IP.

The router is Netgear WNDR3700v1 with fw 1.7.2.

Please let me know what log or error files I need to look to debug this problem.

Thanks,
Traidua

Thanks for quick response.

Looks like the issue is at http://www.tracemyip.org which is used to get local ip.
Here is from logread.

I wish these urls was in a conf file so I could update myself. Looks like I have to wait for a new build in order to get that fix.

check_local_ip_urls.c

char default_ip_lookup_url_data[][MAX_LOOKUP_URL_LENGTH] = {
"http://checkmyip.com",
"http://www.ipchicken.com",
"http://www.tracemyip.org",
"http://checkip.dyndns.org",
"http://checkip.org",
"http://www.ip-address.org",

I think you're right.

I thought it was supposed to try that list in order though. Strange.

You could modify it yourself and recompile if you don't want to wait?

[traidua]

Yes, I believe so. It tries that list in order and rotate the urls so that the traffic equally distributed to all sites in the list. I guess the issue is it doesn't get the error from http://www.tracemyip.org. Otherwise, it can try the next url.

[Lantis]

I've tried out the tracemyip address and it works successfully.
Can we get details on your network setup. I want to know why it would falsely report a 127 address.


EDIT:
well bugger me... i reproduced your error lol.

ahhhhhhh....
You don't happen to be using my Adblock plugin do you..?

i just discovered that tracemyip.org is getting blocked by it as an ad.

I'll fix that in the next build lol.
If you aren't using that plugin then i can keep testing for you.


If you are, add "www.tracemyip.org" to the /etc/white.list file on your router and then from the router gui go to Firewall>Adblock and select "update blocklist".

[traidua]

Lantis, thank you for looking at this issue.
I actually got a workaround. I am using ip_source and ip_interface so it works without go through that list.
