Forgive my ignorance but why can I use ssh over serial but not Ethernet in single user mode?

I know I've got someone there who can give the machine a kick should it be needed, it's more a case of seeing if/what I can do it from here rather than trying to arrange the whole upgrade over a phone. Okay, now this is where I get to embarrass myself with a stupid question, what about stringing some commands together? Would something like # shutdown -r 0107251200 # shutdown now; make installworld actually work or is it more likely to destroy the whole system beyond any hope? >Hope this helps, Thanks to all Kevin -- kevin@caomhin.demon.co.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
