I found a work-a-round for those who do not wish to use ipv6. First disable net-pf-10 in /etc/modprobe.d/aliases by changing:
"alias net-pf-10" to "alias ipv6 off" "alias net-pf-10 off" "alias net-pf-10 ipv6 off" and then add "blacklist" and "ipv6" to /etc/modprobe.d/blacklist You will also need to remove or comment out all ipv6 addresses in /etc/hosts. After that you can reboot(or possibly even restart your network, though I did not test that). When you computer is back up type the following command in console: ip a | grep inet6 If nothing shows up then you should be good to go. After doing everything above, XDMCP started working on IPv4 again and as a positive side effect, I could use SCP again(didn't work before either, because SSH was listening on tcp6). In conclusion, this doesn't look like a KDM specific problem.
