	If you type:

ulimit -a

       you should see output that looks like:

core file size (blocks)  1000000
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      8192
cpu time (seconds)       unlimited
max user processes       2048
pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  2105343

	The 'open files' parameter is the one you're interested in.
It's a kernel tunable on every version of UNIX I've ever used, but I
don't know how to tune it under Linux.

	That would be the old MS-DOS value.  In my experience, UNIXes
have gone for powers of 2.  I've never seen a value less than 32, and
the 32 I saw was almost 10 years ago.  On the current version of Tru64
it defaults to 4096.

Have fun (if at all possible),
