I am searching for some tool like a DynDNS updater - but I am looking for a free one. The tool should report the IP change of the server, so I can access it always. Is there any free tool/service which support this ? Thank you.
Check your router as some routers have this function build in..
DynDNS has a free updated client, or you can update it from many consumer routers.
yey, no-ip.org ... it´s free (just subdomains like hello123.no-ip.org). u can intall it form debian using apt-get install no-ip. U first must register at www.no-ip.org
EveryDNS used to have this, but I switched to DynDNS because I found out my router has support for DynDNS.
