External Tiny Utilities
This is a list of tiny utilities whose functionality is not provided by
busybox. If you have additional suggestions, please send an e-mail to our
dev mailing list.
|Dropbear has both
an ssh server and an ssh client that together come in around 100k. It has no external
dependencies (I.E. it does not depend on OpenSSL, using a built-in copy of
LibTomCrypt instead). It's actively maintained, with a quiet but responsive
an extremely simple Mail Transfer Agent.
a tiny ntp client. BusyBox starting from 1.16.x also acquired ntpd applet.
In a gui environment, you'll probably want a web browser.
Konqueror Embedded requires QT
(or QT Embedded) and some bits of KDE. The Dillo
was requiring GTK+ (but not Gnome), now it is FLTK based.
Or you can try the graphical version of links.
pyvm is a minimalistic
toy toolchain containing various programs (www browser, pdf viewer, windowing environment
on linuxfb, ssh, git, pgp, etc) in a 2MB tarball.
Although busybox has built-in support for shell scripts, plenty of other
small scripting languages are available on the net. A few examples:
| A small standalone perl interpreter that can be built from the perl sources
via "make -f Makefile.micro". If you really feel the need for perl on an embedded
system, this is where to start.
|If you just want a small embedded scripting language to write new
code in, this Brazilian import is lightweight, fairly popular, and has
a complete book about it online.
|The PLAN9 shell. Not compatible with conventional bourne shell syntax,
but fairly lightweight and small.
|A well known language for fast and small programs, decades old but still
in use for everything from OpenBIOS to computer controlled engine timing.
|An embedded implementation of PHP (C Library).
