Hello, Is there any clean way to find out the name, or better yet the ID (since ID are immutable while names are not), of a tunnel device allocated from /dev/tun ? The question was already raised here, but I could find no answer: http://lists.freebsd.org/pipermail/freebsd-net/2004-March/003338.html If not, would it be possible to add, say, an ioctl() on tun/tap devices to return their ID (which could be converted to a name via if_indextoname()), or something similar? That should retain full backward compatibility... Or maybe there is another way to configure the tunnel a la ifconfig with only the file descriptor?? Thanks, -- Remi Denis-Courmont http://www.simphalempin.com/home/
