IPv6 & Konqueror

[Just17]

On this new install of PCLOS (fully updated) it appears that Konqueror Web Browser is first trying IPv6 and then IPv4 causing a big delay in connecting to web sites.

As - for the present - I have no need of IPv6 I decided to disable it completely.

lsmod  |  grep  ipv6

Showed the ipv6 module is loaded, so I arranged to not load it in future.

I added the following two lines to /etc/modprobe.conf file

Code: [Select]

alias  net-pf-10  off
alias  ipv6  off
No more delay with accessing websites.

On reboot

lsmod  |  grep  ipv6

showed that the ipv6 module is no longer loaded.

Now back to almost instant connection with website like www.pclinuxos.com/forum 

Other browsers did not appear to be hampered by the presence of the IPv6 module.

I don't know why anyone would want to do that UNLESS they got big problems with the internet...

I thought he made it very clear.

Well now ........  the delays have reappeared ........  somwhere between 10 and 20 seconds before a new page will begin to load ......  and ofentimes it halts during loading for some 10 secs.

I checked, and the IPv6 module is loaded again .....  despite the fact that the edits to the /etc/modprobe.conf file are still intact.

This delay, now that I checked, is also affecting Firefox, but not Iron which is what I most often use.

I disabled IPv6 in FF, and now will go for a reboot to see if that ensures the module does not get loaded, in which case Konqueror should also have speeded up.

.....  be back shortly ......

Changing the settings in Firefox   about:config  to disable IPv^ appears to have done the trick.

Immediately after a reboot, checked and the IPv6 module is not loaded, and Konqueror shows no delay at all when accessing a new site/page.

Seems all is good again 

[Just17]

That didn't last long!

A few minutes later I began to notice delays again when using konqueror ......  and sure enough the IPv6 module is again loaded! 

Code: [Select]

# rmmod ipv6
ERROR: Module ipv6 is in use by xt_TPROXY,nf_defrag_ipv6
defrag?? ?? ??

I wonder what this is that is loading the module ........

I wonder what this is that is loading the module ........   

May be you are running miredo-client service ?

defrag in this case should means "IP packet defragmentation" ...

possible solution: disable IPv6 in Network Center -> Advanced settings
if the above doesn't work, (it's working for me), try to blacklist the module IPv6

In truth I never heard of miredo-client until you posted ......  so I guess I'm not running it 

Will have to check out your solution, thanks.

OK, tried disabling IPv6 in Network ......  no good.

The other modules are not loading, but IPv6 is ......  and will not die!

So, blacklisted IPv6 and rebooted .......  now it seems to finally be gone!!

Thanks for the help

there is still another option:

ipv6 module provide two option:

# modinfo ipv6
filename:       /lib/modules/2.6.38.8-pclos3.pae/kernel/net/ipv6/ipv6.ko.gz
alias:          net-pf-10
license:        GPL
description:    IPv6 protocol stack for Linux
author:         Cast of dozens
srcversion:     0D112B4107DB781635BB558
depends:
vermagic:       2.6.38.8-pclos3.pae SMP mod_unload modversions 686
parm:           disable:Disable IPv6 module such that it is non-functional (int)
parm:           disable_ipv6:Disable IPv6 on all interfaces (int)
parm:           autoconf:Enable IPv6 address autoconfiguration on all interfaces (int)

along with:

options ipv6 disable=1

in /etc/modprobe.conf

should also work.

Well, I was wrong ........  just checked again a couple of minutes ago and got this .....

Code: [Select]

# lsmod | grep ipv6
nf_defrag_ipv6          4857  1 xt_TPROXY
ipv6                  266625  2 xt_TPROXY,nf_defrag_ipv6
IT IS BACK!!!!!!!!!!!   Arghhhhhhhhh!!!!!!


/etc/modprobe.conf now has the following entries .....

Code: [Select]

alias ipv6 off
options ipv6 disable=1
options disable_ipv6 =1
I am in the middle of something now and cannot reboot .......  so if you see anything wrong with those entries please let me know.

Thanks.

[AS]

options disable_ipv6 =1

you don't need both options, but if you want to use the second one, it should be:

options ipv6 disable_ipv6 =1

[Just17]

options disable_ipv6 =1

you don't need both options, but if you want to use the second one, it should be:

options ipv6 disable_ipv6 =1

Thank you for the correction ......  was distracted ......  I intend to leave both there .......  that should not cause a problem -- I think --  or will it?

Code: [Select]

alias ipv6 off
options ipv6 disable=1
options ipv6 disable_ipv6=1

Don't know, I'm using only this one, without ipv6 related issue.

options ipv6 disable=1

I will report again after I get a chance to reboot ...
