A DHCP IP updater

I use UltraVNC almost religously to repair computers. As of today I work on computers all over my town. The problem is, is that all of my clients have a DHCP addresses. This is very annoying. Right now, I use a third party tool to email,ftp, or upload a website to me with the users changed IP address. Wouldn't it be nice to have this built in to UltraVNC? Which would run with the winVNC service or even a seperate service which would accomplish this!

I think you could script this and run it as a service on the client machines. Another method would be (depending on the supported OSs).

Since Windows 2000, there exists an API called DhcpRegisterParamChange() which will notify a service/program (which you should write then) of changes. This service could then just upload the new IP. Even easier to implement it as a Perlscript or other executable which just gets the new IP posted (e.g. encrypted). This would not even require uload capabilities of the service/program.

But really, this is very specific, you should write this program yourself or ask someone to do it for you.

I am sure this has been mentioned in the past, but some of us use a dynamic DNS service, such as dyndns.org or no-ip.com. You can use a free third party utility (many are available from the sites mentioned) to update an available URL and subdomain that you get from them. The service is free.

I use UltraVNC to support remote clients for my job and my sidejobs, not to mention remote access of my computers at home. My account with dyndns.org certainly makes it simpler to access remote locations that use DHCP.

We use Win2003, Coyote Linux firewall, DynDNS with DNSerSvc.exe service updater (text based config), repeater and DSMplugin.

DynDNS updater in service (repeater, or server), will be nice feature.

I need only internal LAN DNS to connect.

Thank you for nice software.
