Any extra thoughts welcome. I wonder if you have your terminology a little skewed. Single User mode does not just mean that only one user is allowed on the machine. It is probably an inappropriate name for the situation actually. It really means that almost all of system services, utilities and applications are shut down and only very basic kernel stuff is up and running. You have to run that single user from the console (or remote console). This is a little different from SysV Sun kind of single user run setting where you can just kick off all users, but have almost all of the system still up and running. That is kind of a partial shutdown. BSD doesn't really have that, though I suppose you could simulate it by moungin stuff and carefully starting things from its single user mode - create a script that will do what you want, but... You could do other things to prevent any other users to get on the fully running system and only allow yourself. But, I don't think what you want is what is called "single user mode" for that. ////jerry > > Thanks, > > Alex > > - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - > Alexander Sendzimir (owner) 802 863 5502 > MacTutor: Apple Mac OS X Consulting info@mactutor.biz > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
