This is a program designed to speed up writing tapes on remote tape drives. Requirements are shared memory and locks which normally means that these are supported in your kernel. [for FreeBSD/NetBSD, this means you MUST have a kernel with options SYSVSHM compiled in - markm] Buffer has been tested under SunOS 4.0.*, SunOS 4.1.*, Solarix, HP-UX 7.0, and Gould UTX 2.1A (sv universe). The program splits itself into two processes. The first process reads (and reblocks) from stdin into a shared memory buffer. The second writes from the shared memory buffer to stdout. Doing it this way means that the writing side effectly sits in a tight write loop and doesn't have to wait for input. Similarly for the input side. It is this waiting that slows down other reblocking processes, like dd. I run an archive and need to write large chunks out to tape regularly with an ethernet in the way. Using 'buffer' in a command like: tar cvf - stuff | rsh somebox "buffer > /dev/rst8" is a factor of 5 faster than the best alternative, gnu tar with its remote tape option: tar cvf somebox:/dev/rst8 stuff

Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
