I've used the star tech devices in the past. Most modern systems have
some sort of RDP or Java thing on the IPMI that mostly work.

If your hardware has a Baseboard Management Controller (BMC) or Integrated
Lights Out Management (iLOM) that supports IPMI v2 or later use it. IPMI
v2 allows for Serial over LAN access [0]. I use SoL with Linux on Dell
hardware (BMC) using OpenIPMI tools. You set the BMC to attach to a serial
port and have a getty listen on the port as well. On my hardware there's
one virtual and one physical serial port so I configure the SoL set up on
ttyS1 (second serial) so I don't tie up the physical serial port.

You could create similar set ups with serial consoles/terminal servers and
servers that have serial ports on them ... have a getty listen on the
serial interface.

If a terminal/console is enough and you don't need VGA/X-Windows access
then SoL or a physical serial connection would suffice.

An IP-KVM is not worthless, but why buy more hardware if you have other
options? (SoL capability especially)
