Password Safe is a free Windows utility from Bruce Schneier and
Counterpane Labs which
allows you to keep your passwords securely encrypted on your computer. A
single Safe Combination--just one thing to remember--unlocks them all.
Check Password Safe's new home on
SourceForge to see if a newer version has been released yet.

for aliens, for when you're writing SciFi and get stuck for a name... ;-)

libpcap-compatible library for Windows. Libpcap is the basis for most UNIX
sniffer and packet tools, such as namp, nc, tcpdump and dsniff.
Check out the
OpenBSD FAQ relating to IPFilter for a VERY good and clear example
of IPFiltering, which is similar to the Linux IPTables or IPChains, and
which is a great example of firewall rules in action! See also:
- The OpenBSD project produces a FREE,
multi-platform 4.4BSD-based UNIX-like operating system. Our efforts
emphasize portability, standardization, correctness, proactive security
and integrated cryptography. OpenBSD supports binary emulation of most
programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and

- I have combined my LogSwap and CPFWBack tools, and added
my extract_patch tool into CPFW1TK--the Check Point Firewall-1
Tool Kit. LogSwap and CPFWBack work under both Windows and UNIX.
Extract_patch is unnecessary under UNIX.
(288,965 bytes) has the scripts and all other binaries needed to run. It
also includes the UNIX scripts just for fun, and it has
some other bonus stuff. It is a self-extracting ZIP archive.
(10,251 bytes) just has the UNIX scripts and ReadMe files.
Extract_patch was created for extracting Check Point patches
under Windows, without installing WinZip,
since Check Point are now distributing all patches in TGZ format. But it
will work for any TGZ (or .tar.gz, or .gz or .tar) you wish to extract
under Windows, without having to install WinZip. It combines Win32 ports of
the GNU tar.exe, gzip.exe and md5sum.exe utilities, so you can unpack and
verify *.tgz files.
LogSwap archives or "rolls" Firewall-1 logs. It

gzip.exe for Win32.
CPFWBack greatly automates the annoying process of backing up
Firewall-1 configurations. It includes CPFWBack.cmd, zip.exe,
vdate.exe for Win32 and CPFWBack.sh for UNIX.
- I've also created an add-on called
jpcshrc for the default csh
configuration in Nokia's IPSO 3.4.1-FCS5. It sets the csh prompt to your
current working directory, and add some aliases (mostly DOS commands,
since I can't remember what OS I'm using).

- Tom Horsley's NTP Time for
Windows is a nice NTP client program. It is free, but is a client only,
and can be configured to talk to only one NTP server at a time. NTP works
much better when referencing a pool of servers. BUT, it allows you to use
NTP to time-sync a hardened NT Firewall server. The NT Resource kit
TimeServ will not run
with the NT Workstation service disabled or removed (which it should be
on a firewall!!!)
