Hi I'm sorry for the second e-mail but the uname is. FreeBSD unix.swebase.com 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Fri Nov 5 04:19:18 UTC 2004 root@harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 We haven't even recompiled the kernel since the install. It was supposed to be a temporary machine but turned into a development machine for me and some other developers.
