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 cp -pR #{prefix}/tun /Library/StartupItems/
|
||
|
|
|
||
|
|
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
