Re: [uml-user] uml_switch configuration

[Asim S. <asi...@ya...>]

I've tried all that you suggested but I still have not been able to
solve the following problems:

a) I run uml_switch and I bring up two clients, 
"linux umid=one eth0=daemon ..." and
"linux umid=two eth0=daemon ..."
In both of the instances, eth0 gets assigned the SAME IP address in
BOTH instances and thus I can't get the two clients to communicate. I
even tried eth0=daemon,fd:fe:c0:a8:00:0f for the second client.

b) Suppose I have only ONE client but I want to have two eth devices
configured. I tried doing a "config eth1=daemon,fd:fe:c0:a8:00:0f" from
the uml_console. An ifconfig -a shows the eth1 device but a
/etc/rc.d/init.d/network restart does NOT bring it up.

Any suggestions will be greatly appreciated,
Thanks,

-- Asim

You might also try typing the command `ifconfig -a` in the client.

That is not correct. The only time you need to provide a MAC address is
when the client will be using DHCP or similar, as the MAC address is
otherwise set when the interface receives an IP address.

This is correct.
