DragonFly kernel List (threaded) for 2008-05
New Utilities in base: vknetd and vknet
vknetd creates a virtual bridge for any number of vitrualized
connections and can then backfeed it all into a (possibly if_bridge'd)
vknet can connect a local and remote machine's networks together over
a SSH link. It can tie into a TAP interface or /dev/vknet on both ends
and will pass packets in both directions over the link.
A recent HEAD kernel is required to use these utilities as they use
the new SOCK_SEQPACKET socket type. VKernels are also able to make
use of vknetd sockets.
The general idea is multi-fold.
* First, to provide a network interconnect accessible to userland.
* Second, to provide a secure, easy to use network virtualization
* And, lastly, to simplify the operation of multiple vkernels. vknetd
has no limitations on the number of interconnects.
While there is some overlap with with if_bridge feature, or the use of
IPSEC, these utilities have distinct capabilities of their own which
can greatly simplify network glue.
