If you have additional suggestions, please send an e-mail to our 8dev mailing list. 9 10<br><br> 11 12<table border=1> 13<tr> 14 <th>Feature</th> 15 <th>Utilities</th> 16</tr> 17 18<tr> 19 <td>SSH</td> 20 <td><a href="http://matt.ucc.asn.au/dropbear/">Dropbear</a> has both an ssh server and an ssh client that together come in around 100k. It has no external 21dependencies (I.E. it does not depend on OpenSSL, using a built-in copy of 22LibTomCrypt instead). It's actively maintained, with a quiet but responsive 23mailing list.</td> 24</tr> 25 26<tr> 27 <td>SMTP</td> 28 <td><a href="ftp://ftp.debian.org/debian/pool/main/s/ssmtp/">ssmtp</a> is an extremely simple Mail Transfer Agent.</td> 29</tr> 30 31<tr> 32 <td>ntp</td> 33 <td><a href="http://doolittle.icarus.com/ntpclient/">ntpclient</a> is a 34tiny ntp client. BusyBox has rdate to set the date from a remote server, but 35if you want a daemon to repeatedly adjust the clock over time, try that.</td> 36</table> 37 38<p>In a gui environment, you'll probably want a web browser. 39<a href="http://www.konqueror.org/embedded/">Konqueror Embedded</a> requires QT 40(or QT Embedded), but not KDE. The <a href="http://www.dillo.org/">Dillo</a> 41requires GTK+, but not Gnome. Or you can try the <a href="http://links.twibright.com/">graphical 42version of links</a>.</p> 43 44<h3>SCRIPTING LANGUAGES</h3> 45<p>Although busybox has built-in support for shell scripts, plenty of other 46small scripting languages are available on the net. A few examples:</p> 47<table border=1> 48<tr> 49<th><language></th> 50<th><description></th> 51</tr> 52<tr> 53<td> <a href=http://www.foo.be/docs/tpj/issues/vol5_3/tpj0503-0003.html>microperl</a> </td> 54<td> A small standalone perl interpreter that can be built from the perl source 55s via "make -f Makefile.micro". If you really feel the need for perl on an embe 56dded system, this is where to start. 57</tr> 58<tr> 59 60<td><a href=http://www.lua.org/pil/>Lua</a></td> 61<td>If you just want a small embedded scripting language to write <em>new</en> 62code in, this Brazilian import is lightweight, fairly popular, and has 63a complete book about it online.</td> 64</tr> 65 66<tr> 67<td><a href= http://www.star.le.ac.uk/%7Etjg/rc/>rc</a></td> 68<td>The PLAN9 shell. Not compatible with conventional bourne shell syntax, 69but fairly lightweight and small.</td> 70</tr> 71 72</tr> 73<tr> 74<td><a href=http://www.forth.org>forth</a></td> 75<td>A well known language for fast and small programs, decades old but still 76in use for everything from OpenBIOS to computer controlled engine timing.</td> 77</tr> 78</table> 79 80<p>For more information, you probably want to look at 81<a href=http://buildroot.uclibc.org>buildroot</a> and 82<a href=http://gentoo-wiki.com/TinyGentoo>TinyGentoo</a>, which 83build and use tiny utilities for all sorts of things.</p> 84 85<!--#include file="footer.html" --> 86 87
