In order to effectively manage UNIX, Linux and Cisco machines from a remote location, one needs to redirect the console to the serial port and hook this to a serial console server. It is also good on a security stand point because all the messages sent to the console are logged on the console server, thus serving in forensic investigations. Ideally, to have even the BIOS at the serial ports, you need to run Oracle/Sun Microsystems or IBM pServers machines. Most newer x86 servers can redirect their BIOS to the serial port. Do it, it's great! With the console server, you have access to everything the server has to offer from the comfort of your office.
