How do you disable ipv6 support for kde applications

[ihavenoname]

I disabled the loading of the ipv6 module but it seems that kde applications don't understand this as it takes them much longer to communicate with on-line content then non-kde applications.

For example firefox will begin loading a website immediately whereas konqueror will wait a while, almost as if it is trying to use ipv6.

The ipv6 issues have been fixed for tunneling over ipv4.
I recall konqueror problems a while back and it needed fixed.
enable ipv6 and see if it helps, as it could be a time out issue.

I know if you mess with Ubuntu's ipv6 that package manager wil die.
so maybe the website has ipv6 and konqueror is tryint to use it?

Also look up BZ# for konqueror about it.

acutally wanted to use this to test if somethings were

I actually wanted to disable ipv6 because I thought it was causing konqueror to not connect. This is not the cause as I recently tried konqueror with ipv6 in archlinux and it works so it's something wrong with the fedora konqueror packages. Thanks for your help.

You should post the REAL problem (some KDE apps seem slow under some unstated config) instead of making pot-shot guesses that ipv6 is to blame and having everyone here guessing at the real issue. F9 has a brand new KDE which is may be part of your problem.

Wild guesses like "almost as if it is trying to use ipv6", have no place in diagnosis. Run wireshark or tcpdump to gather evidence for your suspicions. Otherwise it just misleading bunk. For all you know dbus is malfunctioning or you have a bad proxy setup. Just guessses - you must present the problem, the config and any evidence.

IPv6 is often blamed for problems, but it is almost never the actual problem. OTOH ipv6 is rarely used outside Japan and some labs/campuses. It probably will never catch on for general Inet access. I agree disabling IPv6 is a decent idea, but it's not generally part of any problem syndrome - it's just useless for most ppl.

your analysis would be correct if I had actually wanted to have people solve this problem for me. What I wanted was information on how to disable ipv6 myself. A.) because I wanted to do it anyways and B.) because one of my theories was that ipv6 attempts might have slowed the connection so long that it time out.

It was but ONE of the many things I was doing to try and discover the problem. It was not my only solution. I found that if I put direct ip addresses in that I would get a connection and the problem may have been related to DNS. I do not know.

To remove it, add to /etc/modprobe.conf:

# No IPv6
install ipv6 /bin/true
install ip6_tables /bin/true
install ip6table_filter /bin/true

In /etc/hosts, comment out (or remove) this line:

::1 localhost6.localdomain6 localhost6

That is the only way to disable ipv6, and you have to reboot after making those changes. You don't need the ip6 tables lines, but they'll get loaded anyways and just waste memory otherwise. Or they did as I seem to recall which is why I have them.

If, however, the kde programs are hardcoded to probe and attempt to connect via ipv6
anyways, this won't help you. I don't have kde installed right now to tell if this is an actual
problem or not.
