Hi, To learn more about IPv6 I have setup an IPv6 only jail in FreeBSD 8-STABLE. The IP address assigned to the jail is part of a public IPv6 prefix that I obtained from my ISP. The jail is started with 'ip4=disable' as a startup option to the jail command. The jail works fine. I can ping(6), traceroute(6), resolve IP addresses and a DNS resolver that I reach on its IPv6 address. Now, I trying to use apache22 to setup a web-server (once again only reachable via IPv6). And here the problem starts. I just can't get the thing to start, it core-dumps immediately:six# /usr/local/etc/rc.d/apache22 start Performing sanity check on apache22 configuration: [Sat Jan 15 15:27:54 2011] [crit] [Sat Jan 15 15:27:54 2011] file config.c, line 1982, assertion "rv == APR_SUCCESS" failed Abort trap (core dumped) Starting apache22. [Sat Jan 15 15:27:54 2011] [crit] [Sat Jan 15 15:27:54 2011] file config.c, line 1982, assertion "rv == APR_SUCCESS" failed Abort trap (core dumped) /usr/local/etc/rc.d/apache22: WARNING: failed to start apache22 The apache version is apache-2.2.17_1 from the FreeBSD port collection using all the default options. The httpd.conf file is pretty straightforward. Unfortunately, I get a mail bounce 552 spam score (5.3) exceeded threshold (in reply to end of DATA command) if I include it in this email, so I only post the changed lines compared to the distrubtion httpd.conf: Listen [2001:980:1312:6::1]:80 ServerName six.ipv6.deze.org:80 LoadModule php5_module libexec/apache22/libphp5.so DirectoryIndex index.html index.php AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps The hostname of the jail is resolvable (forward and reverse) via DNS and is also in /etc/hosts. But the hostname has only an AAAA record, but no A record in DNS. I tried to debug the apache and apr code, but that is not every easy either. So, my final hope is this list. Does anybody have a solution, or a clue how to proceed with debugging this problem?
