@Ricardo: Amen.
Ubuntu is a nice "end-user-friendly" distribution. I respect what they
are trying to do. But there comes a point where bailing is the only
sensible option. Fedora Core 12 works like a champ. Networking works.
Sound works. Package management works. Java works. OpenOffice works.
etc.
@Hillshum re-read what I wrote. Disabling IPV6 /does not/ resolve the
symtpom.
But for me it no longer matters. I've bailed and switched to Fedora Core
12. It works.

[karmic regression] all network apps / browsers suffer from multi-second delays

@Ricardo Fernández As I mention above, in my case, after disabling IPV6,
I still had the same symptoms. Terribly long delays making any kind of
network connections (all wired). I noticed here that it seemed to be
related to making more than one network connection at a time.
Based on forum posts el

@Laurent Yes, I was thinking the same thing since it's now fixed for me.
However, if you do some searches, even in the Ubuntu forums I think,
you'll find dozens if not hundreds of posts from people saying they
turned off IPV6 but still had slow lookups/connectivity. There was one
thread somewhere
@Laurent yes. /ALL/ network access regardless of application is
affected. Please re-read the report I wrote. Yes, this has nothing to do
with the IPv6 DNS lookup problem. IPV6 record lookup was one issue
that would cause the slow connections so many people are experiencing.
My point is that wh
@Laurent Ok, I spent some more time researching this, playing with
various scenarios.
1. Fedore Core 12 running in VMWare exhibits the same problem as Ubuntu
9.10 running natively.
2. WinXP running in VMWare does /not/ exhibit the problem.
3. Cent OS 5.4 running in VMWare does exhibit the proble
@Laurent As I mentioned, I have turned off ipv6 in grub:

>From what I am observing here, the IPV6 problem is not the sole cause of
slow lookups and connection speed. Despite turning off IPV6, running my

I am also seeing random network slowdowns on my Dell N-Series using a wired

local connections (e.g. connecting to Apache on the same box, which was not the
case with the ipv6 bug and nsswitch.conf issue ).

I can confirm that there is something else, beyond IPV6 lookups, that is
causing timeouts.

mistaken, contains the IPV6 fix.
