Hi Christian,

this is exactly my question - seems that I have to define policy for 2 connections - to /bin/bash and to vfs, why not 1?
                     <policy label_prefix="/bin/bash"  port="8888" />
                        <policy label_prefix="vfs" port="8888"/>
while I assume single chain like nic -> tcp_terminal -> bash 

Now I understand that implicitly I assume that tcp_terminal is like telnet server.
May be my assumption is wrong?

sorry for misreport - initially I try to run on qemu + nova which configured for port 5555 and local host.
then I try to switch to linux. it give the same errors while run a bit faster, so, I now keep it (using linux tap driver)

for test above I definitely use "telnet 8888"
