Re: Re: Ping

I still can't get it to work as expected: -If the computer is on, it works like a charm. -If the computer is off, but exists in DNS/hosts, the script is timeouted. -If the computer doesn't exist in the DNS/hosts, the script is timeouted. I even tried setting the fsockopen timeout to a few seconds, but it still gets a script timeout with an php error. I can't seem to be able to block a fsockopen attempt to an inexistent/offline computer, which would be the answer to my problems. -If the computer exists, and is online, but has the fix to hide port 139 (thus avoiding nukeing DoS attacks), the script answers that the computer is NOT online. Do you get the same result?
