Topic: Dynamic-DNS

[Pete]

Hello

I've configured SME5.5 to use dyndns.org, but the auto update does not work.
yes my dyndns account name is correct and yes my password is correct.

Does anyone know how the script works. I have found something in /sbin/e-smith/dynamic-dns/dyndns.org but it's a dead end street for me.
B.T.W. the log file /tmp/dyndns.log is empty

I now have to manually go and modify the IP address in dyndns and the whole point about dyndns is that it is DYNAMIC.

Luckely my ISP doesn't force a IP address change too often, but it would be nice if i'd be able to get it working.

Thanks for helping me out.

what does 'grep dyndns.org: /var/log/messages' give you?

[Jason Slater]

I'm having the same problem and the response I get is:

Oct  3 10:31:22 net-server dyndns.org: Unknown response . Status was 0.

[Pete]

I have tried the grep, but I get nothing.
It's really like the dyndns.org updater is not functioning at all!?!

Is there any way I can find out if it is running.

It sounds stupid but If I'd know how to run the update manually I could make a script and run it from cron.hourly.

This would fix the problem for me. I'm just using e-smith as a webmail system ( and a pretty good one ) so if it is unreachable for an hour it would be no problem.

[Jason Slater]

I think I found the solution to my problem: ddclient.  It's available as an RPM and was fairly easy to install and configure and it already seems to have worked.

My guess as to why it's not working with the e-smith software would have something to do with their NIC2 protocol - maybe in a future update?

Anyways, here's the link:

http://clients.dyndns.org/unix.php?service=dyndns

Choose the Linux/Unix clients and it's right at the top.

Hope this helps.

I installed ddclient, configured ddclient.conf.

when I try ddclient it returns me the error : Skipping host: address: 'login' is an invalid option.

I'ts probably me. I find the conf file quite hard to understand. It's not too clear what needs to be set and what not.

I really need some help to make this thing work.

[Jason Slater]

Did you take the comments out in the appropriate places?

Maybe if you cut-and-paste your conf file in a message I could take a look at it for you (change usernames and passwords, of course).

I'm not sure what else I can offer.

[Tom Docking]

I concur with Jason's recommendation of ddclient.

Not only is it easier to tweak the config files, but you can also update multiple domains at the same time. (including "My Custom DNS" for yourname.com domains)

I've even got a non-dyndns.org domain being updated, all from the one client app.

Another *major* advantage, is that it can read the IP address from an ADSL modem using PPPoA, such as the Alcatel SpeedTouch Pro issued by Telstra down here in Oz.

Hi,

Since I've installed ddclient it keeps on sending messages to my admin mailbox with the following contents:

WARNING:  skipping host: Address: 'login=' is an invalid login.
WARNING:  null password specified for host (bypassing.
WARNING:  skipping update of pdcq.dyndns.org from 213.224.83.131 to
213.224.83.35.
WARNING:   last updated Sat Oct 12 12:03:44 2002.
WARNING:   Wait at least 30 seconds between update attempts.

The funny thing is that this 213.224.83.85 isn't even the IP address of the eth1 ( the network card connected to my ISP )settings.

Here is the contents of the config file:

I've got these lines commented out in my config:
proxy=proxy.telenet.be:8080 # default proxy
server=members.dyndns.org # default server

Other than my having the wildcard enabled my config file looks very much like yours.

Maybe your ISP has a proxy that's getting in the way somehow?

Hope this helps.

[pete]

I'm going to try it but it seems odd that you comment out:
server=members.dyndns.org # default server

As this defined which dynamic dns server the script needs to connect to.

Thanks

[pete]

I know my ISP doesn't allow direct web traffic and you cannot surf without configuring the proxy.

But even with the correct proxy setting I cannot get it working;

Anyway it's odd that ddclient keeps on sending mails with the error : Skipping host: address: 'login' is an invalid option.

I tried looking in the README document available on the net about ddclient but I didn't find any useful info there.

[Jason Slater]

I'm not sure what to offer at this point...  Other than trying to get some info out of your ISP (do you think that ddclient is maybe trying to log into the proxy server?) I'm stumped.

[David Lemstra]

I'm not exactly an expert, but I've had more success using the web status page. Try uncommenting this part instead.

>## To obtain an IP address from Web status page (using the proxy if defined)
>#use=web, web=checkip.dyndns.org/, web-skip='IP Address' # found after IP

However, I've had trouble getting it working again myself, now that I've upgraded to 5.5, but it may be worth a try.

Best of Luck!

[pete]

I think I've got it working now.

When you type wrong arguments after ddclient ( like ddclient -stop ) it will generate a help list.
I printed this list and built my own ddclient.conf from scratch.

If you then start ddclient with the arguments '-daemon=0 -debug -verbose -noquiet'
at every step you can see on the terminal what he's doing.

I have been able to update the ip address manually, but how can I be shure it continues working?

do I need to add an entry in cron ?
