OS X 10.7 Support about shim

[erunion]

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: apenwarr/sshuttle@4c1a505

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

@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 !

@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.
