[User-mode-linux-devel] 2.3.51 Networking *smile*

[William S. <wst...@po...>]

Good afternoon, Jeff and all,
	I'm working on networking for UML - I finally have it
functioning!  Thanks for the pointer, Jeff.
	I'll summarize what I've learned in a bit.  One note, though.  
After bringing the interface up, typing:
ifconfig umn down
	successfully returns to the command prompt, but promptly hangs uml
with a:
umn_read had error, errno = 9
	on the console and the idle thread at 99% on the host.

	It appears the uml patch hardcodes the address used on the host
side.  How would it be if, on the uml side, the user was expected to do:

ifconfig umn 172.20.0.244 pointopoint 172.20.0.253

	From which the uml-kernel could extract the pointopoint address
and execute

um_ifconfig sl0 172.20.0.253 pointopoint 172.20.0.244

	, rather than having to hardcode an address.  If two uml's were
running at the same time, then you could have 4 separate addresses, two
for each pointopoint link.

	I suppose Nirvanha would be to have sl0 on the host be able to
talk to multiple UML's on a simulated ethernet cable:
host OS sl0:	192.168.12.1/24
uml1 umn:	192.168.12.2/24, default route ->1
uml2 umn:	192.168.12.3/24, default route ->1
uml3 umn:	192.168.12.4/24, default route ->1
	Cheers,
	- Bill 'way too many damn suggestions' Stearns
