I mean no offense toward anyone, but let's leave the legal wrangling and 
armchair quarterbacking on the subject of open source licenses to the 
attorneys.

The complexities of the topic are best addressed outside the scope of this 
list.

He might want to consider liability insurance, or word it in his support
contract that he cannot be held liable for anything out of the support
he is providing. This needs to be done by an attorney, and should be
part of any support contract.

Well, he wants to provide INSTALLATION and support. Installation
constitutes distribution, distributing copies of snort is subject to the
GPL terms, which really aren't all that unreasonable.

Heck, technically he could just leave a copy of the source tarball on the
machines he installed it on and he's fully compliant. I just stated the
"CD and printed license" as a "best practice" recomendation.


As far as I know you can take Snort and do with it as you want. I see
other variants of Snort out there and commercial companies use it all
the time in their commercial devices; anything from switches, to full
blown IDS devices.

That part is not true. There are certain limitations on what you can do
with snort. There's not many, but there are some. For example I cannot
use code directly from snort in a non-open source product.

You really should read the license.  BSD licenses are generally "do
whatever, but it's still my copyright", but GPL licenses are "do
whatever, but it must always remain open source when you're done with it".

Snort is GPL licensed, not BSD.


Isn't that the beauty of 'Open Source'?

True, although some OS software is protected against "embrace, extend and
extinguish" tactics by GPL licenses.

The relative merits of BSD vs GPL vs other OS type licenses is the
subject of a great many flame wars, really the only relevant bits here
are how GPL differs from "do whatever".
