Reading some of the posts on dslreports suggests that some people
have been able to pull an IP from Verizon by cloning the MAC address
of the router. How can I do this in NetBSD 4.0? A quick google
turned up nothing useful -- some mention of 'netgraph' in FreeBSD
but nothing for NetBSD. Doesn't look like the NetBSD version of
'ifconfig' has the 'ether' option....
This was posted a few weeks ago.
# ifconfig tapN create
# sysctl -w net.link.tap.tapN=f0:0f:f0:0f:f0:0f # which is wanted MAC address
# ifconfig bridgeN create
# brconfig bridgeN add tapN add epN
# ifconfig tapN up
# ifconfig epN up
# brconfig bridgeN up
for obvious reasons, this doesn't work on wireless networks, making
NetBSD unsuitable for e.g., penetration testing.
Is there a reason we don't allow changing MAC address with ifconfig?
