Dynamic DNS

[v8dave]

Hi all,

Has anyone done any work with Dynamic DNS on the Netburner?

I am developing a remote monitoring system that is going to be deployed over GPRS. The GSM network I am going to use has a static IP that changes each time you connect and I am looking at the use of DYNDNS.ORG to give it a domain for easy access to the unit.

I have found some source code to do this but I can't find any documents on the actual protocol for this. I could work it out from the source code but I prefer to know the details so I can properly implement it.

Anyone else done this and know where I can locate documents on the protocol?

Cheers,
Dave...

I haven't done it on a netburner yet, however I did it from a vbscript a while back. You should be able to port this example over pretty easily. Btw, the example is for OpenDNS.

Code: Select all

function UpdateOpenDNS()
  'Update OpenDNS account by posting the OpenDNS network label after loggin in

  'Required: OpenDNS Account & Label
  oUsername=""
  oPassword=""
  oOpenDNSNetworkLabel=""

  Set xml = CreateObject("Microsoft.XMLHTTP")
  On Error Resume Next
  xml.Open "GET", "https://updates.opendns.com/nic/update?hostname=" & oOpenDNSNetworkLabel, False, oUsername, oPassword
  xml.Send
  If Not Err.Number <> 0 Then
    if instr(xml.responseText,"good")>0 then
      UpdateOpenDNS = "Record Updated"
    else
      UpdateOpenDNS = "Error updating Record"
    end if
  end if
end function

Thanks. I also managed to find some code for DYNDNS and it seems to be very similar to what you posted. I'll be trying it out over the next few days.

Cheers,
