Our ISP says we are running Solaris version 2.6.
LISTSERV SHOW VERSION says "Running under: SunOS 5.6"

So which Unix platform version do I choose for updating LISTSERV classic
(SunOs?)?  Here are the choices:
 > ===========================================================
 > Solaris.tar.Z
 > Solaris86.tar.Z
 > Solaris-OCI.tar.Z
 > SunOS.tar.Z
 > =============================================================

The verbal descriptions in the LISTSERV "supported versions" text document
do not explicitly name each tar file that corresponds with each detailed
description.
