Server script without built-in sockets

[Judd Pickell]

I wasn't aware of a linux distro that didn't have perl as part of its
release installation. I am curious now as to which ones don't? I am
usually working in suse, rh, ubuntu and debian, which last I checked
all did have it. So I wonder if you mean ones like puppylinux or small
usb drive running linux setups. Anyways.. you have my curiosity
piqued.

Sincerely,
Judd Pickell
