#26805 [Opn->Fbk]: fsockopen fails when hostname is given

ID: 26805 Updated by: wez@php.net Reported By: mark dot salisbury at hp dot com -Status: Open +Status: Feedback Bug Type: Sockets related Operating System: hpux PHP Version: 4.3.4 New Comment: Sounds like an ipv6 problem; can you try configuring PHP using --disable-ipv6 and see if that "fixes" the problem? (either your v6 stack is broken, or it is misconfigured). Also, it would be good if you could test a php5 snapshot with that script (just the CLI version will do), as it has some code to detect and avoid this problem at runtime. Previous Comments: ------------------------------------------------------------------------ [2004-01-05 20:18:17] mark dot salisbury at hp dot com Description: ------------ I was using fsockopen in a script, which worked fine until I upgraded from version 4.2.0 to 4.3.4. Oddly, I found a workaround for the bug by changing my code from: $fp = fsockopen($server_name, $port, $errno, $errstr); to: $fp = fsockopen(gethostbyname($server_name), $port, $errno, $errstr); Reproduce code: --------------- fsockopen($server_name, $port, $errno, $errstr); Expected result: ---------------- Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: host nor service provided, or not known in /local/apache1.3/htdocs/php_includes/http_post.php on line 45 Warning: fsockopen(): unable to connect to saturn:81 in /local/apache1.3/htdocs/php_includes/http_post.php on line 45 (errno=0 and errstr="error 0", I believe) The reason I believe this is a bug is that: a) Isn't fsockopen going to do something similiar to gethostbyname() if you pass a hostname and not an IP address to fsockopen? Why does it work when I pass it an IP address and not the host name? I would expect gethostbyname to fail also if my problem were external (DNS). b) everything worked fine until I upgraded PHP today. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26805&edit=1
