Sloggi 0.1.2 - A Solaris Uname JacketCopyright © 2002, 2003 by Konrad Rieck
Sloggi is a thin loadable kernel module for the Solaris Operating Environment (OE) 8 and 9. It allows the administrator to change the name, the release and the version of the operating system on a running system by intercepting the uname() system call. It is a coarse way of creating a compatible environment for application that check for the information returned by uname() (or the command uname).
Sun tries to keep newer release of the Solaris OE binary compatible to older ones. Therefore you can assume that many applications designed for Solaris 8 will operate on Solaris 9 and vice versa. Unfortunatly, several of these applications explicitly check for the correct release of Solaris. Using Sloggi you are able to find out if a software works on your system on your own and don't need to rely on a developer who added the release check.
Just a Sloggi for your Solaris system, it's all about feeling comfortable, see www.sloggi.com.
No bug in the default install in nearly 5 years! Just kidding. There are probably some bugs around, but I am not an entomologist. Also important to mention, Sloggi is a registered trademark of Triumph International AG. But do they also dress Solaris systems?
The installation of Sloggi is rather simple. First configure the Makefile in the src/ directory. Just step through the file and (un)comment the definitions according to your setup. Choose to whether use the Sun C Compiler or the GNU C Compiler to compile the module. If you are running a 64 bit kernel, you have to use the Sun C Compiler or the GNU C Compiler version 3.x.
# make install
Usage: slogctl [-hV] [-s sysname] [-r release] [-v version] [-m machine] Options: -s sysname Set the name of the operating system. [Default: SunOS] -r release Set the operating system release level. [Usually: 5.8, 5.9, ...] -v version Set the the operating system version. [Default: Generic] -m machine Set the machine hardware name (class). [Usually: sun4m, sun4u, i86pc, ...] -h Print this help screen. -V Print version information. No options restore the original uname() setup
If you install the Ximian GNOME Desktop on a Solaris 8 system and then upgrade to Solaris 9, you will be surprised because Ximian Red-Carpet will refuse to update your system and complain about the incompatible Solaris 9 system.
You can now temporarly turn your Solaris 9 system into the release 8, update the GNOME components using Red-Carpet and later return to your original release.

If you are really crazy, you can do very, very strange things with Sloggi. You could for example setup a normal Solaris 8 box somewhere on the net and obfuscate your system's users by changing your system's value completely.
