route_dst_netlink: can't find interface "tap0"

[Chris <deutronium () gmail com>]

Hi guys,

First off congrats on you're excellent work :)

I'm using r29928 from the SVN repository.

I'm just having problems with nmap not recognising a particular interface.

If I run a connect scan as a normal user, chris@icarus:~/Desktop$ nmap
192.168.1.222
It works fine.

If I run the same connect scan as a root user:

route_dst_netlink: can't find interface "tap0"

Even though "ifconfig tap0" shows the interface is up:

tap0      Link encap:Ethernet  HWaddr 4a:40:62:24:53:5e
          inet6 addr: fe80::4840:62ff:fe24:535e/64 Scope:Link
