tohle jsem nemel na mysli myslim nejakou funkci ktera proste vyhodi true nebo false pokud najde nebo nenajde ip (dostane odezvu) ale jinak diky za radu nevi nekdo jak na to ?
Tak prostě jen zkus otevřít nějaký soubor z toho serveru třeba funkcí fopen() - předpokladem je, že znáš adresu souboru, který tam opravdu je...
pokud se podaří, server jede, jinak zřejmě ne
pokud se podaří, server jede, jinak zřejmě ne
pouzil jsem funkci fsockopen zadal jsem IP a kontroluje jestli ho najde tak funguje spravne ale v pripade ze to IP mu neodpovi tak nepokracuje dal :( a to nevim jak prekonat zkousel jsem vymyslet zpusob jak to jinak delat ale na nic jsem neprisel toto je muj scriptik
for ($i=1; $i<= 255; $i++)
{
echo ('<br>'.$prvni .'.'. $druhe .'.'. $treti .'.'. $i);
$fp = fsockopen("$prvni.$druhe.$treti.$i", 80, $errno, $errstr, 30);
if (!$fp)
{
echo "$errstr ($errno)<br>\n";
echo('<font color="red"> nejede </font>');
}
else
{
echo('<font color="green"> jede </font>');
}
}
}
toto funguje do doby kdy ty IP adresy odpovidaji na port 80 ale jakmile nenajde odpoved tak se kousne s chybovou hlaskou ze vyprsel casovy limit
for ($i=1; $i<= 255; $i++)
{
echo ('<br>'.$prvni .'.'. $druhe .'.'. $treti .'.'. $i);
$fp = fsockopen("$prvni.$druhe.$treti.$i", 80, $errno, $errstr, 30);
if (!$fp)
{
echo "$errstr ($errno)<br>\n";
echo('<font color="red"> nejede </font>');
}
else
{
echo('<font color="green"> jede </font>');
}
}
}

Mozno si mal na mysli toto..
Naposledy ked som to skusal tak to fungovalo.
pracuje to s ICMP sockets
tusim som to trochu aj upravil od originalu aby mi to fungovalo
