mhhh - but the bridging howto at
http://edeca.net/articles/bridging/questions.html
tells:
Q:
Why can multiple UMLs on a bridge talk to the host but not each other?
A:
By default, every UML instance uses the same MAC address so ethernet can't
distinguish the two hosts. You need to assign each UML a unique MAC address
by specifying it as part of the eth0 argument, like so: "eth0=tuntap,tap1,
FE:FD:00:00:00:01".
and i can acknowledge this, as far as i remember. i always specify the mac
adress on the commandline - being "safe" this way.
so - what is right ?
is there differnt neworking code in different uml versions ?
