OS X 10.7 Support

[designerbrent]

I saw your note in the README about support for 10.7. I'm wondering if you have any idea if and when this support might be coming.

Thanks! This looks like an amazing tool!

FWIW, here's what happens when you try to install it on 10.7:

$ sudo ./setup.sh

sshuttle (https://github.com/apenwarr/sshuttle) had this exact same problem on 10.7. apenwarr and co solved it with this commit, which is a bit hacky but fixes the problem for good: https://github.com/apenwarr/sshuttle/commit/4c1a505e37f6a0c59acfd347c290ab9d3258f6a7

Confirming this problem with exactly same symthoms as jonursenbach posted. Is there any hope for us on 10.7? :)

[cbowns]

@n1313 You can manually apply the sshuttle fix with:

sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.Boot "Kernel Flags" "net.inet.ip.scopedroute=0”

then convert the plist to xml:

sudo plutil -convert xml1 /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

After you’re done, confirm the change like this:

% sudo defaults read /Library/Preferences/SystemConfiguration/com.apple.Boot
{
    "Kernel Flags" = "net.inet.ip.scopedroute=0";
}

and make sure it’s in XML form (otherwise the kernel can’t read it at boot)

cat /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

then reboot. Then try installing shim again.

@cbowns I tried your solution since I'm on 10.7 but it didn't work out. After reboot, my "Kernel Flags" turned into "Kernel \n Flags" and installing the shim returned the same "sysctl: oid 'net.inet.ip.scopedroute' is read only".

Any help would be appreciated !

[cbowns]

@nobleskine Sounds weird. I’d be happy to help you get it working: my contact info is at http://cbowns.com/contact

Ok, that script does bad things to your kernel plist (like nuking any other flags you may have set), and it doesn’t even work. This should fix it.
