PHP IMAP and POP3 through Tor

[Andy Dixon]

Hello,

I thought I might try my luck and see if anyone can help point me in  
the right direction.

I am trying to open a socks5 connection to a localhost tor socks  
server, connect to host X and go from there.

The underlying code works fine for HTTP requests, but for POP and  
IMAP, it seems to hang and die. /var/log/tor/debug.log shows loads of  
this:

As far as my socket shows, its connected but gets no data back. Here  
is my code ($host is the host to connect to and $ICL_PORT is the port  
number):

  	    $fp= pfsockopen('127.0.0.1', 9050, $errno, $errstr);
             $buf["send"] = pack("C3", 0x05, 0x01, 0x00);
             fwrite($fp, $buf["send"]);
             $buf["recv"] = "";
             while ($buffer = fread($fp, 1024)) {
                 $buf["recv"] .= $buffer;
             }
             $response = unpack("Cversion/Cmethod", $buf["recv"]);
             //if ($response["version"] == 0x05 and $response 
["method"] == 0x00) {
             if (ip2long($host) == -1) {
                     $buf["send"] = pack("C5", 0x05, 0x01, 0x00,  
0x03, strlen($host)).$host.pack("n", $ICL_PORT);
                 } else {
                     $buf["send"] = pack("C4Nn", 0x05, 0x01, 0x00,  
0x01, ip2long(gethostbyname($host)), $ICL_PORT);
                 }
                 fwrite($fp, $buf["send"]);
                 $buf["recv"] = "";
                 while ($buffer = fread($fp, 1024)) {
                     $buf["recv"] .= $buffer;
                 }
                 $response = unpack("Cversion/Cresult/Creg/Ctype/Lip/ 
Sport", $buf["recv"]);
                 if (!$response["version"] == 0x05 and $response 
["result"] == 0x00) {
                 	return false;
		}
                 $conn->fp = $fp;


Any ideas would be gratefully received!

Thanks

Andy
