In order for TUN/TAP network devices to work, the tun/tap kernel extensions
must be installed by the root user:
sudo cp -pR #{kext_prefix}/tap.kext /Library/Extensions/
sudo cp -pR #{kext_prefix}/tun.kext /Library/Extensions/
sudo chown -R root:wheel /Library/Extensions/tap.kext
sudo chown -R root:wheel /Library/Extensions/tun.kext
sudo touch /Library/Extensions/
To load the extensions at startup, you have to install those scripts too:
sudo cp -pR #{prefix}/tap /Library/StartupItems/
sudo chown -R root:wheel /Library/StartupItems/tap
sudo cp -pR #{prefix}/tun /Library/StartupItems/
sudo chown -R root:wheel /Library/StartupItems/tun
If upgrading from a previous version of tuntap, the old kernel extension
will need to be unloaded before performing the steps listed above. First,
check that no tunnel is being activated, disconnect them all and then unload
the kernel extension:
sudo kextunload -b foo.tun
sudo kextunload -b foo.tap
EOS
end
end
