ID: 14740 Updated by: salvag3@netscape.net -Reported By: l0cky@sn0wmen.fsnet.co.uk +Reported By: salvag3@netscape.net Status: Open Bug Type: Sockets related Operating System: Win98 and Win2k PHP Version: 4.1.0 New Comment: The timeout doesn't work if the host don't respond on the requested port :-( os: linux redhat 7.2 php 4.0.6-7 apache 1.3.20-16 Previous Comments: ------------------------------------------------------------------------ [2002-01-28 12:19:57] korpse@p16.pub.ro well, me too! os: win xp professional apache 1.3.22 php 4.1.1 (win32) the code: $fp = fsockopen($hname,139, &$errno, &$errstr,3); if(!$fp) echo "$hname is not responding on port 139 "; else { echo "$hname is alive"; fclose($fp); } the problem: the 3 secs timeout does not work ------------------------------------------------------------------------ [2001-12-29 09:20:52] l0cky@sn0wmen.fsnet.co.uk ok to clarify.. seems like this is a common mistake fsockopen() times out ok if the server doesn't exist. The problem occurs when the server doesn't understand what is sent to it afterwards and stalls for a reply (ie, if the port is now used by another service). I'll check the bugs for fwrite(), fgets() etc ------------------------------------------------------------------------ [2001-12-28 12:33:49] l0cky@sn0wmen.fsnet.co.uk A simple query to a server with fsockopen() won't timeout if the requested server is down. $serverquery = fsockopen($host, $port, &$errno, &$errstr, $timeout); The operation times out first (120 seconds), even if $timeout is as low as 1 second; it works fine if I remove unavailable servers from the query list. Sometimes the server crashes if I try the function again before the last operation times out. ------------------------------------------------------------------------ [2001-12-28 12:31:36] l0cky@sn0wmen.fsnet.co.uk A simple query to a server with fsockopen() won't timeout if the requested server is down. $serverquery = fsockopen($host, $port, &$errno, &$errstr, $timeout); The operation times out first (120 seconds), even if $timeout is as low as 1 second; it works fine if I remove unavailable servers from the query list.
