socket & listen

[nimbus]

I've been trying to run the tcp server sample from the docs, which starts like this:

if (($sock = socket (AF_INET, SOCK_STREAM, 0)) < 0) {
echo "socket() failed: reason: " . strerror ($sock) . "\n";
}
if (($ret = bind ($sock, $address, $port)) < 0) {
echo "bind() failed: reason: " . strerror ($ret) . "\n";
}
if (($ret = listen ($sock, 5)) < 0) {
echo "listen() failed: reason: " . strerror ($ret) . "\n";
}

$adress is some ip and $port something like 3600 or what you want. unfortunately, bind() returns an error stating:

bind() failed: reason: Invalid argument

but I can't see what I'm doing wrong here...

any help appreciated. thanks.

I have to ask:
1.) the ip is correct?
2.) port is something that has a processor running on the ip that you are requesting.

If there is not a process running on that socket on that ip then of course it will fail.

hi,

the ip is the ip of the server the script is running at. (right?!)

what do you mean with a "processor running"? the server is actually a webserver and I just want to try to run the script - let's say at port 10004 and connect via telnet to the script.

actually - it's the sample of the docs.

do I have to use a port that's already been used by the webserver? 80? doesnt that mean the webserver would catch the request instead of the script?

thanks!

does anyone have an idea what I could try here?

again - I'm using the server's ip and whatever port I try it fails when I call bind().

anyone? please? with sugar? on top?

thankyou.
