QNX is often used as base operating system for intelligent QoS monitors, not for switching or routing or IDS. IIRC, the PIX OS was developed as a complete OS, but based on some BSD ideas (not code). It is still a software based operating system, but designed with simplicity and security in mind. It still may have software problems, the script kiddies don't have easy access to binary to find its bugs. But since Cisco is the only developer, you need to trust Cisco quality control. It does not even have the number of different eyes looking at it that Windows 2000 does.

Those are completely proprietary operating systems. I mean, look at our product list. We literally sell thousands of products. Many are not IOS or PIX OS based. I'd suggest some of you have read one too many conspiracy theories, but given the nature of this group (myself included), that would just be a PGIO (Piercing Glance Into the Obvious.) ;-) -bill At 03:37 PM 4/18/2002 -0400, Clifford Thurber wrote: >We deman an answer! > >At 02:19 PM 4/18/2002 -0500, Noonan, Wesley wrote: >>The of course you have this: >> >>http://news.theolympian.com/stories/20020304/Business/28667.shtml >> >> >>Wes Noonan, MCSE/MCT/CCNA/CCDA/NNCSS >>Senior QA Rep. >>BMC Software, Inc. >>(713) 918-2412 >>[EMAIL PROTECTED] >>http://www.bmc.com >> >> >> > -----Original Message----- >> > From: Brian Ford [mailto:[EMAIL PROTECTED]] >> > Sent: Thursday, April 18, 2002 12:11 >> > To: Chris Kirschke >> > Cc: Clifford Thurber; Noonan Wesley; Mikael Olsson; >> > [EMAIL PROTECTED] >> > Subject: RE: Digital Legends (was: RE: Microsoft ISA server (Was: Re: >> > Replacingmy old PIX Classic)) >> > >> > Chris, >> > >> > Gee whiz.
