Re: Creating a Terminal Server instance in Linux

[Rob Laidlaw <laidlaw@xxxxxxxxxxxx>]

Its a known issue with dynamips on Linux that the dynamips instances  
cannot talk to the host that is running dynamips, which is where the  
console ports are.  To get around this, you need to configure the  
terminal server e0/0 to map to a tap interface rather then using eth0  
or whatever physical interface you have.  The second task is to  
create a bridging instance and add both the physical and tap  
interfaces to the bridging instance.  Unfortunately, the tap  
interface is create when you start dynagen and  you have to add it to  
the bridging instance after you start the rack and once you stop  
dynamips it will disappear.  You have to keep adding it every time  
you start dynamips/dynagen so it can become a pain.  Another pain is  
that you have to move the ip address of your physical interface to  
the bridging interface or you will not have connectivity anymore.
