[uml-devel] [RFE] con=port

["Sven Köhler" <skoehler@upb.de>]

Hi,

it seem that one has to use con=port:<number> to have UML listening on a 
TCP/IP-port. UML also seems to bind to 0.0.0.0
I'd like UML to bind on 127.0.0.1 only and to bind the socket to a free 
port chosen by the TCP/IP-stack.

i would than do "con=port" and UML would bind each console to another 
TCP/IP-Port. I should than be abled to use mconsole to query which the 
port-number con1-9 are using.

Another point is, that "con1=port:9000" doesn't seem to work with a 
2.6.4-um1 kernel. I was abled to connect with telnet, but no matter 
which key i pressed, i saw nothing. In additon, the mconsole didn't 
work. I could attach mconsole to the UML, but any command blocked and 
never returned to the prompt again.

Another point would be security. Even if UML only binds to 127.0.0.1, 
the port is accessable by any user logged in. But i have no clever idea 
for that.
