Does anyone know how to disable IPv6 in Konqueror in Fedora?
Either by re-compiling it without IPv6 support (which probably means re-compiling a whole lot of other KDE software too), or by disabling support at the kernel level.
So I assume the second way is easier? How would you do the second way?
Add this line in /etc/sysctl.d/disable-ipv6.conf (create the file if it doesn't exist):
net.ipv6.conf.all.disable_ipv6=1
For immediate effect run
sysctl -p /etc/sysctl.d/disable-ipv6.conf
The harder way would be to fetch the kernel sources, copying in the distributions .config file, disabling IPv6 in the config, compiling & installing the new kernel, and re-doing that every time Fedora releases a new kernel package.
I have to ask: why would you want to disable it?
Update: I just read that KDE honours an environment variable KDE_NO_IPV6 . Set it to "true", and it's disabled for all KDE programs, without affecting anything else.
I really don't. I need it when I go to a few of my friends houses. They have absolutely terrible ISP's and IPV6 won't work there. Firefox has a nice setting to deal with this, and chromium is smart enough to deal with, but most other browsers have no idea how to deal with this problem.
