#24785 [NEW]: Warning: fsockopen() [function.fsockopen]: php_hostconnect: connect failed

From: laudanp at yahoo dot com Operating system: Redhat 7.3 PHP version: 4CVS-2003-07-23 (stable) PHP Bug Type: Sockets related Bug description: Warning: fsockopen() [function.fsockopen]: php_hostconnect: connect failed Description: ------------ Please reference: http://bugs.php.net/bug.php?id=21653, as it is the same for this bug report. I was asked to file a new one. The CVS codebase I'm using is: php4-STABLE-200307031530.tar.gz. The following line is where the error occurs in my script: $handle = fsockopen($this-> targetIP, $index, $errno, $errstr, $this-> timeout); You may see the script in action here: http://www.computercops.biz/modules.php?name=TCP_Scanner or http://www.computercops.biz/modules.php?name=Trojan_TCP_Scan I obtain that fsockopen error. It was stated by wez in the above referenced bug report that he removed a duplicate error message. I grabbed the latest cvs after that and it still wasn't working. Below is the code that I include in a parent PHP script. Its the "core" though. Reproduce code: --------------- <?php # COPYRIGHT PAUL LAUDANSKI / COMPUTERCOPS.BIZ $trojans = array("21" => "Nerte 7.8.1", "23" => "TruvaAti 1.2 beta" ); flush(); while (list ($portno, $descno) = each ($trojans)) { flush(); $fp = fsockopen($REMOTE_ADDR, $portno, $errno, $errstr, 1); if(!$fp) { echo "Connection Refused: "; echo "Port $portno used by $descno."; echo "<BR>"; } else { echo "<FONT COLOR=red><B>ESTABLISHED CONNECTION</b>: "; echo "Possible $descno Trojan found on port $portno.</FONT>"; echo "<BR>"; $start = time(); socket_set_timeout($fp, 5); $ccspstrNumberFound++; fclose($fp); } } ?> Expected result: ---------------- Starting Trojan TCP Scan ... Connection Refused: Port 21 used by Nerte 7.8.1. Connection Refused: Port 23 used by TruvaAti 1.2 beta. etc... Actual result: -------------- Starting Trojan TCP Scan ...
