... but the machine architecture is still "i386", as in Intel CISC. Other machine architectures include m68k, powerpc, alpha, hp-ppa, etc. You don't need to worry about this. : (2) : The other thing is that the DISPLAY env variable is set : to "unix:0.0". My question is : shouldn't this variable : be of the form $HOSTNAME:0.0 ? So why is set to "unix:0.0" ? : : And how do I change this env variable on a global basis : (ie for all users) ? It's faster to use a "UNIX domain socket" when all traffic is local as you avoid some of teh overhead of an IP stack. Why waste those milliseconds? : (3) : The last thing is : I'd like to create an environment variable : that contains the following information : kernel version and : machine architechture. e.g. : linux-2.2.12-i686.

Do it in /etc/profile, add this line: export OSVERSION=`uname -r`-`arch` HTH, -- Nathan Norman MidcoNet 410 South Phillips Avenue Sioux Falls, SD mailto:[EMAIL PROTECTED] http://www.midco.net finger [EMAIL PROTECTED] for PGP Key: (0xA33B86E9)
