Apache sets the environment with SetEnv (or at least 1.3 does, I don't run 2*) as it can't inherit one from user www since it doesn't have one. So have you had a look at httpd.conf and .htaccess on each machine? BTW, one machine uses an "old" PATH with /usr/X11R6/bin in it. That disappeared some time ago. That may or may not be a clue. In short, I think this is probably an Apache question & you might have more informative answers from there. Sorry I can't be more helpful but quite a few Apache people run FreeBSD and they're likely to be more help than I am. Regards, -- Frank Contact info: http://www.shute.org.uk/misc/contact.html
