Troubleshooting on OS X

[pjv]

I might be able to help with this. Here is an email that I sent to Guus some time ago:

>> Having moved onward from setting up a private tinc router-mode mesh on my routers and linux servers, I finally got around to installing and setting tinc up on my mac laptop. When I wanted to set up the mac so it could see my tinc network (but NOT route everything through it, road-warrior style), I couldn’t find the right config anywhere and when I tried to just copy the configs I used on my linux server boxes (setting them up with something like <ifconfig $INTERFACE 10.112.1.1 netmask 255.255.0.0>) so it would be a single leaf node and be able to see and be seen by the rest of the mesh, I was thwarted by the FreeBSD ifconfig command which forces you to create a ptp link when configuring a tun device by specifying both the IP address of the device AND a specific device on the other end of the ptp link (you cannot specify a network).
>> 
>> This is a tinc-up script that mimics the linux behavior. you may want to add this to the wiki page here: http://www.tinc-vpn.org/examples/osx-install/ <http://www.tinc-vpn.org/examples/osx-install/>
>> 
>> 
>> tinc-up (for OS X yosemite):
>> 
>> #!/bin/sh
>> 
>> ifconfig $INTERFACE 10.112.1.2/16 10.112.1.2
>> route add -net 10.112.0.0 10.112.1.2 255.255.0.0


hope that helps.
