I'm not sure I really understand your concern, but the following fact may help you. - You don't need firewire to access dcons. dcons can be accessed via KVM without -t option. - By default(without -g option), dconschat listen on only 127.0.0.1. You cannot access it from outside of localhost. Currently, we can only have one dcons device on a system. You may need multiple dcons port for multiple jails... /\ Hidetoshi Shimokawa \/ simokawa@sat.t.u-tokyo.ac.jp PGP public key: http://www.sat.t.u-tokyo.ac.jp/~simokawa/pgp.html At Fri, 10 Sep 2004 15:24:25 +0200, Hendrik Scholz wrote: > > Hi! > > I've been thinking for this for a few days and eventually had the time > to have a first look at it. > > What I'd like to do is basicly running > '/usr/libexec/getty dcons dcons' inside a jail and allow the host system > to access the console. > It's easy to do using the dconschat TCP feature (dconschat -rTC 12345) > and using telnet to connect but I don't like the idea of allowing telnet > connections from remote systems to important services. > > So my solution (only had a quick look at the code) should work like this: > > - write a firewire-like extension for dconschat, i.e. 'dcons -j myjail' > that connects to the console on the local jail 'myjail' > - build a miniature version of /etc/ttys in the jail to allow > configuration. > - make sure the comserver-con port works with this extension :) > > Are there any comments or recommondations? > > Thanks, > Hendrik > > -- > Hendrik Scholz - <hscholz@raisdorf.net> - http://www.wormulon.net/ > drag me, drop me - treat me like an object > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" >
