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.
