Archive of "endangered software"
On this page you find useful software which seems to have
from the Internet after the original authors closed
down their homepage.
Those are usually small but very useful programs that I
like and use myself.
picocom -- a small rs232 serial terminal for linux
Picocom is an easy to use serial terminal for linux. It is much
easier to use and understand than minicom. It is ideal for
simple tests or configuration tasks that involve a RS232
connection or an emulated RS232 connection over USB. The
tuxgraphics.org avrusb500 programmer can e.g configured via
serial interface. picocom is ideal for that:
picocom -l -f x -b 115200 /dev/ttyUSB0
To exit picocom you type: C-a C-x
picocom was written by Nick Patavalis and used be available
from http://efault.net/npat/hacks/picocom/ Recently that site
became unavailable. A local copy is available here:
download picocom-1.4.tar.gz, 41295
Good news, Jul 2009: The software is no longer endangered.
Nick put it on Google [http://code.google.com/p/picocom/]
ssync -- a minimalistic but fast filesystem sync/mirror
Ssync is a minimalistic filesystem synchronization utility. Its
primary goals are reliability, correctness, and speed in
syncing extremely large filesystems over fast, local
Ssync works well on large filesystems and can handle
filesystem objects with unusual and non-ASCII characters in
their names while correctly preserving all symbolic and hard
links and all mode bits.
Its a great tool to backup files to an external USB drive or a
second disk in the same computer. You can run it as a deamon in
the background but the easiest is to use it like this:
ssync -F -v 0 -f /some/source/directory -t
The tool is written by Michael W. Shaffer but it is now off the
net. It used to be available from
Here is a local copy of this great software:
download ssync-2.3.tar.gz, 44989 bytes
Version 2.3 was written in 2002-11-06 but it still compiles and
runs with no problems on Linux and Mac.
pump -- a small and easy to use dhcp client
pump appeared first in the redhat linux distribution.
Its advantage over dhcpcd is that it is only one one file.
You just run "pump -i eth0" and the interface is configured
Here is a local copy:
download pump-0.8.24-patched-2009.tar.gz, 89042 bytes
download pump_0.8.24.tar.gz, 79790 bytes
download pump-0.8.14.tar.gz, 38905 bytes
Pump is also still avilable on debian: http://ftp.debian.org/debian/pool/main/p/pump/
udhcpc -- a small dhcp client
udhcpc is also very lean and small. It consists
of two things the udhcpc binary and a script in
udhcpc is part of busybox.
You can run udhcpc such that it just configures the interface and
then quits (no daemon): udhcpc -i wlan0 -q
This is the best way to use a dhcp client especially in small home
networks. You don't have to worry about duplicated address assignment
just because you are not running a dhcp client daemon. All dhcp server
do either a ping or send out an arp request before they handout
a new address. In other words as long as you use that IP address it will
not be assigned to anybody else.
Here is a local copy:
download udhcp_0.9.8cvs20050303-linux.tar.gz, 50851 bytes, the package contains also code for a dhcp server. The client is called udhcpc
Here is my /usr/share/udhcpc/default.script:
default.script (unix text file)
HTML tidy for linux
HTML tidy is the most useful program if you do web design.
It is a command line utility to check the syntax of html pages.
Most of the time you would use it like this:
tidy -e TheWebpage.html
This will just print errors and warings about the html code.
You can then edit the file and correct them.
Tidy is maintained at http://tidy.sourceforge.net/ the problem
is however that they do no longer provide source code
tar-balls. So here is a tar file for linux. Just unpack it and
download tidy-20051026-forLinux.tar.gz (1032 kbytes)
Blender treemaker (L System) for linux
This is the treemaker L-System originally written by Armagan
(www.geocities.com/blenderdungeon/lsystem) adapted for use
under linux. The package includes installation instructions and
documentaion. See the included README for details.
Treemaker is a python script for the 3D progam Blender
(www.blender.org) to generate trees.
rlpr -- send postscript files to a remote unix network printer
rlpr sends a postscript file directly to a remote unix printing system without
the need to run a local print spool or define anything in
It is very useful when you are "on the road" and
temporary connected to a network with unix printers. Most network
printers from HP or Xerox will inter-work directly with rlpr. Example:
rlpr -Hphaser6250 -Plp myFile.ps
Alternatively you can specify printhost (-H) and printer (-P) also
via the environment variables RLPR_PRINTHOST and PRINTER.
rlpr was written by Peter Memishian and used to be available at http://truffula.com/rlpr .

xerox phaser 6250 -- patch for: jam at registration roller paper at fuser
This is a firmware patch for the popular xerox phaser 6250. The printer is
still being sold (not from xerox directly but dealers still have stock as of 2013). Xerox has however removed a vital patch for a paper jam. This special case of a paper jam is the result of
a design flow. You can find more details here: jam at registration roller paper at fuser firmware patch.
