Summary: fsockopen will not work on 'localhost'
Status: Closed
Type: Bug
Package: Sockets related
Operating System: Windows XP

I think this issue still exists in 5.3.x, including the latest 5.3.17.
I had a VPS with Debian 6.0.6 and PHP 5.3.17-1~dotdeb.0 and was unable to connect to smtp.gmail.com
via fsockopen until I disabled (sysctl net.ipv6.conf.all.disable_ipv6=1) IPv6 on the VPS.
A strace of the fsockopen call while IPv6 was enabled showed that an attempt to connect via IPv6 was
made and timed out, followed by no attempt to connect via IPv4. Additionally, I had no problem
connecting to smtp.gmail.com via openssl s_client so the issue appears isolated to fsockopen.
I've also noticed at least one other claim of this bug in 5.3.x (ref: http://drupal.org/node/805834#comment-6260564)

Log: - fix bug #50953, socket will not connect to IPv4 address when the host has both ipv4 and ipv6
addresses

This is indeed a bug.
The problem is that PHP doesn't detect a connection was actively refused and instead times out
on it.
The scenario where the address has both ipv4 and ipv6 addresses, the service is only listening on
ipv4 and ipv6 has precedence results in:
a) trying ipv6
b) time out
c) fail
instead of
a) trying ipv6
b) connection refused
c) trying ipv4
d) success
I've attached a patch that fixes the issue.
