===== Systems =====

==== Debian on USB ====

A [[BootDebianUSBCryptoTutorial|tutorial]] on how to install an bootable encrypted [[http://www.debian.org|debian]] system on a USB key.

===== Utilities =====

==== Trickle ====

Userspace bandwidth shaper, both standalone and co-operative.

<ifauth astfgl>
==== PDFdecrypt ====

{{sw:pdfdecrypt.txt}} A short perl script which does RC4 description and clears the protection bits.
 There's several more rights-management tools and utilities [[http://www.cs.cmu.edu/~dst/Adobe/Gallery/|here]], too.

==== tcc ====

Tiny C Compiler [[http://fabrice.bellard.free.fr/tcc/|homepage]].

==== Tesseract OCR ====

Tesseract is picky about it's TIFF input file, and I've found that it's best to use //pnmtotiff// to generate them.


===== Tips =====

==== Local joe Config ====

//~/.joerc//

  :include /etc/joe/joerc
  :main
  markb           .k1
  markk           .k2
  blkcpy          .k3
  blkmove         .k4
  blkdel          .k5
  nmark           .k6
  dellin          ^D
  undo            ^Z
  ffirst          ^F
  fnext           ^N
  exsave          ^X
  save            ^W

==== SSH Passwordless Login ====

Run ssh-keygen to create the private and publc keys.

  bash> ssh-keygen

Now append the contents of **//.ssh/identity.pub//** to **//.ssh/authorized_keys//** on the remote host.

==== Large Xterm for X ====

  xterm -aw -leftbar -ls -rw -sb -sl 1500 -bg black -fg white -fn -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso8859-1

==== X11 VNC over SSH ====

This script requires x11vnc on the remote host, vncviewer on the client, and a ssh path between the two.

  #!/bin/bash
  
  HOST=$1
  
  if [ "x$2" == "x" ] ; then
        USER=""
  else
        USER="$2@"
  fi
  
  PORT=`ssh ${HOST} "x11vnc -display :0 -bg -nopw -q" | grep PORT`
  PORT=`echo "${PORT}" | sed -e 's/PORT=//'`
  PORT=`expr ${PORT} - 5900`
  
  vncviewer ${HOST}:${PORT}

==== Self Signed Certificate ====

The first step is to create your RSA Private Key.
  openssl genrsa -des3 -out server.key 1024

Once the private key is generated a Certificate Signing Request can be generated.
  openssl req -new -key server.key -out server.csr

Remove Passphrase from Key
  cp server.key server.key.org
  openssl rsa -in server.key.org -out server.key

Generate a Self-Signed Certificate.
  openssl x509 -req -days 36500 -in server.csr -signkey server.key -out server.crt

Install the Private Key and Certificate.
  cp server.crt /usr/local/apache/conf/ssl.crt
  cp server.key /usr/local/apache/conf/ssl.key

Configure SSL-Enabled Virtual Hosts.
  SSLEngine on
  SSLCertificateFile /usr/local/apache/conf/ssl.crt/server.crt
  SSLCertificateKeyFile /usr/local/apache/conf/ssl.key/server.key
