<tt>Hi Christian,<br>
<br>
this is actually a limit of the current release of Netkit. Quoting
from the man page of vstart:<br>
<br>
<blockquote type="cite">
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
There can be at most one ``tap'' collision domain for each user.
Hence, if different virtual machines are configured for using
``tap'' connected interfaces, they also are on the same
collision domain. TAP-ADDRESS is mandatory, but is only taken
into account when a ``tap'' collision domain is first used
(i.e., this is the first interface the current user ever
connected to a ``tap'' collision domain). Otherwise, it simply
ignored.<br>
<br>

This means that you cannot automatically set up two independent
TAP collision domains (with a different subnet for each collision
domain). If you really want to achieve this, you need to set up
the second domain manually, and then attach it to a virtual
machine. Consider that the procedure to set up a TAP interface is
implemented in file $NETKIT_HOME/bin/manage_tuntap.<br>

<div>Hi all,<br>
<br>
</div>
I'm new of netkit envoirement and I have created a
network with these configuration:<br>
<br>
</div>
internet--A--B--C--internet<br>
<br>
</div>
A and B are connected to internet and in the lab.conf
file i have put these line:<br>
</div>
<br>
A[1]=tap,192.168.42.1,192.168.42.2<br>
A[0]=HOME1<br>
B[1]=HOME2<br>
B[0]=HOME1<br>
C[0]=HOME2<br>
C[1]=tap,192.168.43.1,192.168.43.2<br>
<br>
</div>
in the A.stratup. i have written also this line:<br>
</div>
"route add defeault gw 192.168.42.1"<br>
<br>
and in the B.startup this:<br>
"route add defeault gw 192.168.43.1"<br>
<br>
</div>
<div>When i run this network, i test the internet connections:<br>
</div>
<div>I try a simply ping to 8.8.8.8 in this way: "ping -I eth1
8.8.8.8"<br>
<br>
<br>
</div>
<div>It works for "A" but it doesn't work for "B"<br>
<br>
</div>
<div>Does anyone have some ideas about?'<br>
<br>
</div>
