 +====== Portable TOR relay ======
 +
 +Version 0.5
 +
 +Andrea Trentini - 2009
 +
 +tor@atrent.it
 +
 +==== Goal ====
 +
 +Create a qemu (http://​www.qemu.org) image with a
 +small/​minimal linux distro and TOR (http://​www.torproject.org)
 +to have a "​portable"​ TOR relay: just copy the qemu
 +image and run it on any server (even/​especially VPSes) you like.
 +
 +==== Usage ====
 +
 +  * Copy image
 +  * Launch qemu with port redirection (script available)
 +  * Edit TOR config inside guest machine
 +  * Activate TOR (symlink in /etc/rc2.d)
 +  * Start TOR service or reboot guest machine
 +
 +==== Status ====
 +
 +<​del>​Working</​del>,​ now disabled, I had a working image but I switched it off...
 +
 +==== Idea (implementation) ====
 +
 +  * Create qemu image
 +  * Install minimal GNU/Linux version ("​Ubuntu JeOS" was chosen)
 +  * Check TOR is installed and updated...
 +    * add in sources.list (edit to suit your distro):\\
 +      * deb http://​ppa.launchpad.net/​adnarim/​ubuntu hardy main\\
 +      * deb-src http://​ppa.launchpad.net/​adnarim/​ubuntu hardy main
 +    * then '​apt-get install tor'
 +  * Edit /​etc/​tor/​torrc (see appendix 'TOR config'​)
 +  * Config GRUB to activate serial console (so that qemu can be run in the background with no window)
 +  * Install (usually already installed) and activate ssh server (/​etc/​rc2.d)
 +

 + ​ORPort <choose port and use the same number in the qemu activation script>
 +
 + ​DirPort <choose port...>
 +
 +
 +=== Qemu activation ===
 +
 +Shell command to launch qemu:
 +
 +$ nohup qemu -localtime -redir tcp:<​ORPort>::<​ORPort>​ -redir tcp:<​DirPort>::<​DirPort>​ -redir tcp:<​sshPort>::​22 ​ -nographic <​imagename>​ &
 +
 +ORPort, DirPort: see appendix 'TOR config'​
 +
 +sshPort: if you want (recommended!) to access your guest machine activate an ssh server and make it accessible through a qemu mapping
 +
 +If you launch qemu without '​nohup'​ you can access the console directly.
 +
 +=== GRUB config ===
 +
 +Add this to activate serial console:
 +
 + ​serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1
 + ​terminal --timeout=10 --dumb serial console
 +
 +And this must be appended to every kernel line:
 +
 + ​console=tty0 console=ttyS0 vga=normal
