One router & multiple DDNS how to?

[arcull]

Hi everyone. I know this is probably not the right forum for such a question, but anyway I would be grateful for any info you can provide. So, I have a linksys router which has the ability to link it to ddns service. So I did register a free dynamic domain name via DynDNS.com: Free DNS Hosting, E-mail Delivery, and VPS Hosting and entered the right info on my router. It works ok, however I wonder if I registered another ddn, how could I link it to the same router, since there is just one field available for ddns on the router. I thougt I would need this if I want to use more virtual hosts on apache server. I don’t have much experience with apache yet, so please correct me if I’m wrong. Thanks for your help.

If you have only one IP address, surely you can get dyndns.com to map more than one domain name to the same address? I don’t know whether you have to pay for this service though.

Sorry I’m not sure I understand what you’re pointing at, I don’t have a static ip from my ISP, could this be a problem? Thanks again.

Well dynamic IP addresses are exactly what dyndns.com is handling.

The router updates the entry at dyndns.com whenever your DSL address changes. This IP address is mapped from the domain name you registered with dyndns.com. There is no technical reason why it couldn’t be mapped from more than one domain name. But I don’t know if dyndns.com will give you more than one free domain name per IP address. that’s what I was saying.

I understand, but this does apply to the ddns service part, while on the other side (my linksys router) there is option for just one ddns service to select, so this might be the technical part that does make troubles in my case. In other words, my router allows just one ddns service to be attached to it. So I was wondering is there maybe some free software available for linux (suse, ubuntu) which could handle multiple ddns services, like the router does. Or a better option, if there is the possibility to link ddns services together somehow.

do you have a link. Thanks

Since the multiple domain names are handled at dyndns.org, one entry is all you need at your router.

However if you want to update multiple DDNS registrars, e.g. no-ip.com as well, you are out of luck, because your router only runs one update program with one registrar. To update another registrar you would have to run a DDNS client on some other machine. There are such programs just do a search for DDNS clients. The problem is how to detect that the external IP has changed. The router knows when this has happened because the DHCP lease changes, or the PPP connection changes. On another machine you can only poll periodically, and some registrars don’t like unnecessary updates and there is a lag before the address is updated.

You could also run your own router software like IPCop, which allows you to have as many DDNS registrars as you like. But this will require a separate PC, more power, more wiring, etc.

yes you are right, I didn’t know it is that simple I did register another domain name at DynDNS.com: Free DNS Hosting, E-mail Delivery, and VPS Hosting and if try to ping each of both domain names I get reply from my router, cool Thanks again for your help mates.
