Re: Restricting access using IPs

Liam, Not altogether happy with the suggestion below. It works - for now. A more generic solution might be to replace the hard-coded "9" with a call to strrchr() on the last 'dot' character position (minus one). Then it should work on any properly formed IP address. Thereafter parameterise the subnet address portion and things become mobile/re-usable. Regards, =dn > Oops, wrong variable.
