Can't read files from /proc

[MCCALL,DON (HP-USA,ex1)]

Right.
/proc is a virtual file system; the files don't contain any data,
accessing them from LINUX generates data about the system on the fly,
and in fact, on my system, they HAVE a file size of zero.  Which would
explain why clients trying to read them via windows thru samba would
open them and immediately close them - file size zero - as far as they
are concerned, nothing to read.
Hope this helps,
Don
