q-shell - Unix Remote Login And Rootkit Shell Tool. 
Quick Shell for Unix administrator!

q-shell is quick shell for remote login into Unix system, it use blowfish crypt algorithm to protect transport data from client to server, you can get two program: 'qsh' for client, and 'qshd' for server, those program can rename by any name with you prefer.

Compile

Just enter 'make' and it will automation to compile, but, you must input the server key.

Usage

1. Server:

Just run qshd on server:

   $ ./qshd

But, you would like to run after change it to other name, such as:

   $ mv qshd smbd
   $ export PATH=.:$PATH
   $ smbd

2. Client:

Set some environment variable, then run qsh:

  $ export _IP=127.0.0.1
  $ export _PORT=2800
  $ unset _P
  $ ./qsh shell

Now you already login into server $_IP .

More function

1. q-shell include more function to manage system:

put/get files:

$ ./qsh get /path/to/server/file .
$ ./qsh put /path/to/local/file  /path/to/server/file

2. Run a command on server:

$ ./qsh exec 'ls -l /bin'

3. Update server program:

$ ./qsh update /path/to/local/qshd

This function will update remote qshd, and run again.

4. Automation to run command on many server:

$ for i in {10..20} ; do \
      export _IP=192.168.0.$i
      export _PORT=2800
      export _P=key   # set key
      ./qsh exec 'ls -l /bin'
  done

Note: qsh use $_P to fetch server key, so you should erase all history data after to use $_P.

5. Update password

start with version 3.2, you can update the password as below:

  $ ./qsh passwd

about VERSION file

Client and server must have the same main version serial, otherwise, the client cannot to connect the server. the main version serial like, both is 1.x, or 2.x, or 3.x, etc.

For example, if the client version is 1.1, and server is 1.5, so client can connect to the server, but if server version is 2.1, in that way the client cannot connect to server.

file config.h

You can configure the server port in config.h : #define _PORT 2800

And undef _HAVE_MORE_FUNCTION to disable some function.
