Don't get me wrong, jail.conf is a great start,= but simply adding the ability to manage the vnet aspect of a jail does not= make a vimage (what's missing is the built-in support for generating bridg= es as vimages are brought up/down dynamically). > > > > I feel that before I add this to ports I need to reprogram it to use ja= il.conf (not directly). That will simplify its code and [should] make it sm= aller.

This is precisely what I was after when I wrote the vimage packa= ge and its contents. I'm familiar with IMUNES and netgraph fits the bill we= ll (especially with "ngctl dot" being useful in providing visual confirmati= on when you've achieved the desired network layout -- when "ngctl dot | dot= -Tsvg -o netgraph.svg" starts to look like your IMUNES graph, then you kno= w you're making progress toward having the right configuration). --=20 Devin _____________ The information contained in this message is proprietary and/or confidentia= l.
