Description

When attempting to access a MediaWiki installation via IPv6 (using the IP address 2001:5c0:1400:a::df), I get the following error:

Unable to determine IP

Adding a few echos seems to reveal that the line:
$ip = IP::canonicalize( $_SERVER['REMOTE_ADDR'] );
returns nothing.

This is currently running r82006.

What webserver are you running.

This (mostly) works for me on apache. (otoh, when accessing any special page using ipv6 locally I get white screen of death, which i need to investigate futher)

Apache/2.2.14 (Ubuntu) - http://ipv6.helpmebot.org.uk/~stwalkerster/info.php

Might this be related to the fact IPv6 connectivity is being provided via a tunnel from Hurricane Electric?

This (mostly) works for me on apache. (otoh, when accessing any special page

futher)

Just to clarify, I discovered my comment about special pages not working was due to the redirect bug (bug 14977). Its unrelated to your issue.

Can you double-check what $_SERVER['REMOTE_ADDR'] returns? Sounds like we have a couple possibilities:

REMOTE_ADDR data provided by the web server is missing or bogus
REMOTE_ADDR is fine, but for some reason that value doesn't get normalized correctly by IP::canonicalize()

I created a new script in a different directory which just contained the following code:

echo ">" . $_SERVER['REMOTE_ADDR'] . "<";

The output of this is (http://ipv6.helpmebot.org.uk/~stwalkerster/remoteaddr.php):

2001:5c0:1400:a::df<

I hope this is what you wanted.

(The > < is something I commonly use to check for leading and trailing whitespace)

Regression in r77067: prior to that, IP::isValid('2001:5c0:1400:a::df') returned true.

Fixed in r82093.
