Mike: Here are my notes: *SunOS/Solaris Background Information ==================================== "SunOS" is the core operating system comprising the kernel, utilities and basic libraries. "Solaris" is the broader environment comprising SunOS, OpenWindows and networking support. In other words, SunOS is a component of Solaris. Here's how the versions of SunOS and Solaris relate to each other: SunOS 5.3 = Solaris 2.3 SunOS 5.4 = Solaris 2.4 SunOS 5.5 = Solaris 2.5 SunOS 5.5.1 = Solaris 2.5.1 SunOS 5.6 = Solaris 2.6 SunOS 5.7 = Solaris 2.7 (or 7) SunOS 5.8 = Solaris 2.8 (or 8) So, for example, when "uname -a" reports that the server has SunOS 5.6 installed it's actually got Solaris 2.6 installed HTH.
