Yes serial console lines on workstations are not very good. With regard to the idea of running ppp over the serial console. On a sun box if you send a break down the console line the box drops to the boot prom. I expect that there are ways around this behavoir by changing the prom variables. I thought that the point of the serial console line was that it was a last resort communication mechanism because the box has become unresponsive from across the network. Lyndon Marcus J.

However, this is what the customer wants, and I have no say-so, so I need to simply get it set up.Can you at least get them to use a dial-back modem? Or even strong authentication at the dial-in terminal server?Sounds like there's no terminal server there, just dialin on the serial console. :( Warning: workstations often have incredibly lame serial consoles. I don't know about the particular sun boxes you're planning to use but I've had $40,000 screaming hot workstations barely able to handle serial I/O at 38.8k. I've been pondering the secure remote management thing for a while and was trying to come up with decent solutions that are dirt cheap. Haven't tried this, but does anyone see a flaw with: - have a log-in that drops you right into PPP using CHAP - run ip_filt on the workstation to filter access via the PPP interface - let only SSH in over PPP (or whatever other services are OK) mjr. -- Marcus J.
