I am hoping all the reading I have done over the past few weeks makes this instance of the qeustion clearer. Background: 1 Dell 24 Port Switch, WAN connection to my ISP. 5 Dell Serers, each with 2 NICs. 1 NIC on each connected to SWITCH - VLAN 1 -WAN (Many different IP's). 1 NIC on each connected to SWITH - VLAN 2 -LAN (192.168.0/24) Each Server has 2 Serial ports, unused. Each Server has 2 USB ports, unused. All servers running FreebSD 2 Running 4.10 1 Running 5.2.1 1 Running 5.4 1 Running 4.4 (Slave3 Nameserver only). I am ~ 120 miles from the server cage these are located in. So traveling to there is a real pain. I have been reading everything I can find on consoles, ttys, blackboxes, Lantronix serial cables etc, etc ,etc ,etc ... What I am looking to do, is to connect all the servers to a device, or, daisychain them together so that even if I reboot a broken machine, I can still get to a "boot ?" prompt, not to mention single user mode and normal ssh shell prompt. (of course I already have the latter through IP when the machine boots correctly. So my question is, can a machine be made to still be remotely accessable (any method), when file systems are not mounted, or, kernel not loaded? If so, using what setup? -Grant
