I don't need ipv6 so I've turned it off permanently on my pc by adding:
net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1
in /etc/sysctl.conf file
And since then logmein-hamachi service unable to add ham0 virtual interface.
Even if I enable ipv6 back and set hamachi in ipv4 mode:
sudo hamachi set-ip-mode ipv4
It doesn't start interface after disabling ipv6 and rebooting.
Why it doesn't support ipv4-only mode? Is there any way to make it works without ipv6?
