With the release of IRAF V2.11, the old SunOS and Solaris IRAF distributions have been replaced by a single combined distribution. This means that a single installation of Sun/IRAF on a networked server will simultaneously support IRAF sessions running on both the SunOS and Solaris operating systems.
The installation procedure is much the same as with previous individual installations of IRAF on the Suns. The most noticeable change is with magnetic tape support ( tapecap ). The IRAF system will now look for a tapecap file called "tapecap. node , where node is the hostname of the server the tapecap file pertains to. If this file is not found then the system defaults to the generic tapecap file "tapecap". This scheme allows each node in the network to have its own individual tapecap file, providing a different namespace for each node and allowing much smaller files to be used, simplifying administration of large networks. See the article on tapecap elsewhere in this Newsletter, or the new Sun/IRAF V2.11 Installation Guide and Sun/IRAF V2.11 Site Manager's Guide for details.
In a similar way the V2.11.1 PC-IRAF release (mid-January 1998) supports the various PC operating systems as separate binary architectures within a single IRAF installation. For now these distributions include Slackware Linux V3.3, Red Hat Linux V5.0, and FreeBSD V2.2.5, with Solaris x86 and MkLinux planned for the near future. See the installation materials for PC-IRAF for details.
