[Resolved] IPv6 bugs.

[envygeeks]

There are a few bugs in your application of IPv6 which I hope you will fix rather quickly as IPv6 is very important to us.

Problem: Inability to set "IPv6" address in virtual host listeners and apply it to real world.
Example: example.com, www.example.com, [2001:1::2]
Result: 404 for http://[2001:1::2]
Comparison: IPv4 works by application and testing, theoretically IPv6 should too.
Where [2001:1::2] would be the actual IPv6 IP.

Problem: Litespeed web server does not wait long enough before trying to listen again.
Example: Restarting an IPv6 based web server results in the IPv6 listener not being started but IPv4 starting.
Result: Failure
Temporary Fix: Cycling then recycling again in 5 seconds (approximate)

I would also like to see these bugs fixed. I've been transitioning my sites to IPv6 as well.

add this to our to-do list.

I have also noticed this. As our network is native IPv6 a solution would be nice.

Now I fixed it with a set of wrapper/check scripts.

Latest 4.0.12 build should fix this. Please try a manual upgrade.

4.0.13 (FreeBSD 8-STABLE) still has the ipv6 listener problem:

We need the full error log after graceful restart is initiated till the new instance of LSWS starts, usually across two log files if log file are rotated automatically when LSWS restart.

Make sure the per process file descriptor limit is high enough.

I need INFO level log.

[mistwang]

Looks like [::]:280 the wildcard IPv6 is in use
2010-04-02 06:05:17.793 [NOTICE] Recovering server socket: [[ANY]:280]

You cannot create another listener on the same port binding to individual IPv6 address.
