Description daniel 2004-05-25 23:19:58 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a2)
Gecko/20040525 Firefox/0.8

Description of problem:
if you don't disable ipv6 from network-family 10, the name resolution
lookups induce a 20-30 seconds delay (with most routers, both sbc
static and dynamic configurations)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
following steps are trivial:

1. install fc2
2. configure network (make sure you have a dhcp enabled router)
3. instantiate your preferred browser (mozilla family). 
4. go to a web-site you've never gone before... register the status
bar delay message (resolving blah blah blah)

Actual Results:  status bar delay message (resolving blah blah blah)

Expected Results:  should have fast name resolution lookups

Additional info:

if you disable network family protocol 10 (defaulted to ipv6)
everything is cool (like it used to be in red hat 1..9)
Comment 1 Scott Sloan 2004-05-25 23:33:12 EDT
I'm pretty sure this is already know and is not a
redhat-config-network bug. A work around is available

as root:

echo "alias ipv6 off" >> /etc/modules.conf

However this will completely disable ipv6 if you use it. 
Comment 2 daniel 2004-05-25 23:52:11 EDT
right, it's kinda gross to completely disable ipv6...

why not going like:
as root:
echo "alias net-pf-10 off" >> /etc/modules.conf

this should disble only the 10th network protocol family! (this 
solves the problem once and 4all) - it would be nice if you shipp it 
that way...
Comment 3 daniel 2004-05-25 23:53:57 EDT
refine the workaround and shipp it...
Comment 4 Geoff 2004-07-05 12:26:30 EDT
That didn't work for me.

alias net-pf-10 off

at the end of modprobe.conf did.

Now it's like lightning!
