linksys and dyndns problems

Specs: debian, 2.6HT/512mb
Hi,

I have a linksys befsx41 with a fresh new stock firmware. I have created an account at dyndns.com and have successfully updated my router with my user name and domain after 28 days I get an email that says I am stupid and have not update my ip address to their site.

What is going on there was a fix to correct a dynamic dns problem but I do not know exactly what it was as there is no release notes as far as I know.

I am able to use it fine for the first while and then nothing. I have contacted both places linksys says it is dynamic dns and they say linksys.

Dynamic dns also says that I should just download another app that updates the new ip to dyndns.org but this is impossible as the box is not a typical one with a normal OS.

Please help.

Also what is the wildcard and mx feature on dyndns site? and it should not matter if it is a free account or not right?

The software client for updating your ip address at dyndns must run at a normal pc.
There are several clients for Windows and Linux systems.
The dyndns client checks the public ip of the router and checks whether it has changed or not.
If it has changed, it will update your dyndns account with the new ip address.
In this case you have to deactivate the dyndns update at the router.

Just easy and it works fine.

Disadvantage: If the pc for updateing dyndns is not running, dyndns will not be updated.
Router is normally always running and dyndns gets always updated.

I don't know if I was unclear but I CANNOT put one these clients on the box.

Just right !!!
Those update clients can run only on a client machine.
And, as described, the update client at the client pc can get the public ip of your router and update your dyndns account. It's only a workaround for your problem.

If there is a bug in the dyndns update on your router, this can be fixed only by updating the firmware, if available.

Its not so much of a bug in the Linksys as it's missing a critical feature. But then again, I've seen this missing feature in almost every router that does DynDNS- I don't know why developers would be so dumb as to leave it out.

What I'm talking about is the fact that even though you may have a dynamic IP Internet account, sometimes that IP will stay the same for 1, 2, sometimes 6 months at a time. What the router is missing is a "keep alive" function. Unless your IP changes, the router never updates DYNDNS, so after 28 days, your DYNDNS account times out.
That's what they mean by running a seperate updater software client (like DirectUpdate), one that has the option to force an update every 28 days, even if the IP address hasn't changed yet, to keep the DynDNS account alive.

If you can't run an updater client or find a router that has a "force update" option every 28 days, then your only option is to pay the extra money from you ISP for a static IP address.

Assume that I already did an Internet search.

Cool I never thought of it like that. I will look to see if that is what happens.

Would I be able to find out how long I had leased that IP address for? like maybe through a log or by phoning the ISP?

There's no real way to tell. You can try calling the ISP, but I doubt they will or can tell you that information. They'll probably just tell you to get a static IP address.

If you don't mind us asking, what OS is it you have? They have updater clients for Linux, Unix , and Mac.

Oh,

I is a dvr based on the linux 2.4 kernel that I believe is closed somehow but I always thought that was against the GPL. It is Aver Media. And I runs off an IDE flash drive. I haven't really tried poking at it too much but I believe I tried switching to a terminal (tty) and I don't think I could.

I am not at the machine right now but if you want more info I could get it. I will double check to see if I could get something on it.

thanks for your reply analyst

You're right, your options are extremely limited there. Maybe a new firmware will have a DYNDNS option, but who knows. Sorry, and good luck.
