[Discuss-gnuradio] tun/tap OS X for tunneling

[Mark Kuhr]

Has anyone gotten tun/tap running on OS X 10.5 so they can tunnel  
packets to the USRP?

I have the tun/tap driver installed (from http://tuntaposx.sourceforge.net/index.xhtml) 
 and I am already having issues.  So I'm wondering if it is even  
worth using OS X or if I should just start working this in Linux like  
tunnel.py does by default.

The error I'm getting on OS X is:

I type "ifconfig /dev/tun0 create" with permissions to create the  
interface and it says "ifconfig: SIOCIFCREATE: Invalid argument."   
tun0 is listed in the my /dev, so that's rather confusing.

So I'm trying to save some time here.  If anyone has any experience  
with this, any advice would be appreciated.  I'm just tying to connect  
the USRP to some upper layer functionality.

Thanks.
