Re: [uml-user] Multiple UMLs sharing a single tap device

[frank e. <pri...@gm...>]

Similarly to this, I have been running uml_switch with directly specified
subnets as follows:

uml_switch -unix ./s0
uml_switch -unix ./s1

and so forth, where each of ./s0, ./s1, etc. provide a specific connection.

I can then connect various interfaces to the appropriate sockets at start
time by specifying eth0=3Ddaemon,,unix,./s0 eth1=3Ddaemon,,unix,./s1 and so
forth.  So far, I have run a couple of routers in uml, connected through
various ports to different subnets, each connected through a specified
uml_switch subnet.

Best Regards,
Ben
