Sample command line: > > wget -q -O /dev/null > "http://dyndns.domain.com/cgi-bin/dyndns.cgi?host=<hostname>" i was thinking of something precisely along these lines. my goal in having something along these lines is to allow folks who aren't running a *nix to host nodes which fall into the scheme correctly while obviating the complexities associated with the signed updates. i think that we'd need something with a bit more security to avoid replay attacks but i think you're dead on here. > > (The -q is "quiet," removing unnecessary output; the -O /dev/null > sends the output from the CGI script to the bit bucket.
