Pftop is a small, curses-based utility for real-time display of active
states and rule statistics for pf, the packet filter (for OpenBSD)
This is muse, which lists out memory usage categorized by Active, Inactive,
Wired, Reserved, Cache, Buffer, Total, and Free in a manner more friendly
and verbose than vmstat and without as much clutter as top(1).
It is inspired in part by top(1), OS9's mfree, Linux's free, and DOS's
mem /c.
pwd_unmkdb is a program to do the opposite of pwd_mkdb(8). That is, to
give you a textual master.passwd file from a hashed spwd.db database.
Useful if you delete or corrupt master.passwd, and don't have an
up-to-date backup.
Various ELF related utils for ELF32, ELF64 binaries useful
tools that can check files for security relevant properties
Simple utility to tail files/logs to a root X window.
Useful for keeping tabs on log files in X without having
an additional terminal window open.
From the safecat README:
safecat is an implementation of D. J. Bernstein's maildir algorithm.
It can be used to write mail messages to a qmail-style maildir, or to
write data to a "spool" directory reliably. There are no lockfiles with
safecat, and nothing is left to chance. If safecat returns a successful
exit status, then you can be (practically) 100% sure your data is
safely committed to disk. Further, if data is written to a directory
using safecat (or other implementations of the maildir algorithm),
then every file in that directory is guaranteed to be complete. If
safecat fails to write all of the data, there will be no file at all
in the destination directory.
Of course, you know that such a thing cannot be: between UNIX and
the different hardware options available, a 100% guarantee is not
possible. However, safecat takes every precaution possible in writing
your data.
snap is a tool for the management of UFS2 snapshots created
by mount(8). It can maintain hourly, daily and weekly snap-
shots while trying to minimize the disk space occupied. The
snapshots created are labeled with their creation time, and
users can create them manually.
The major advantage over sysutils/freebsd-snapshot is that
it uses hardlink to save diskspace, mark each snapshot with
its creation time and calculates redundancy in a smart way.
TclSyslog provides an easy to use interface to the Syslog daemon.
Xin reads from standard input and splits the data up into sections,
piping each section to a separate command. Optionally it can pad each
section with zeros.
The TAI64N format is a format for time stamps in log files, invented by Dan
Bernstein and used by some of his software, most notably the multilog component
of daemontools. That package comes with a program (tai64nlocal) to convert those
time stamps to a human-readable date.
