I did some research about IPMI on linx and wrote this article for
SysAdmin magazine:


mainly concerned with how to extract cpu temperatures using IPMI.

Here's the story with serial over lan: it does exist in devices that
support the 1.5 version of IPMI, but only as a somewhat proprietary
Intel extension.  I'm not sure if anyone has really ever gotten it to
work well.  The vast majority of IPMI-capable devices out there today
are version 1.5 compliant.

Version 2.0 of the IPMI spec added a standardized SoL.  The linux IPMI
tools support this.  So, if you have devices that support IPMI version
2.0, you should be able to do SoL with linux.

I haven't tried it because all my equipment is IPMI v1.5.
