Shell In A Box<\/strong>\u00a0(pronounced as\u00a0shellinabox<\/strong>) is a web based terminal emulator created by\u00a0Markus Gutschke<\/strong>. It has built-in web server that runs as a web-based\u00a0SSH client<\/strong>\u00a0on a specified\u00a0port<\/strong>\u00a0and prompt you a web terminal emulator to access and control your\u00a0Linux Server SSH Shell<\/strong>\u00a0remotely using any\u00a0AJAX<\/strong>\/JavaScript<\/strong>\u00a0and\u00a0CSS<\/strong>enabled browsers without the need of any additional browser plugins such as\u00a0FireSSH<\/a>.<\/p>\n

In this tutorial, I describe how to install\u00a0Shellinabox<\/strong>\u00a0and access remote\u00a0SSH terminal<\/strong>\u00a0using a modern web browser on any machine.\u00a0Web-based SSH<\/strong>\u00a0is very useful when you are protected with\u00a0firewall<\/strong>\u00a0and only\u00a0HTTP<\/strong>(s<\/strong>) traffic can get through.<\/p>\n

Installing Shellinabox on Linux<\/h3>\n

By default,\u00a0Shellinabox<\/strong>\u00a0tool is included on many\u00a0Linux<\/strong>\u00a0distributions through default repositories, including\u00a0Debian<\/strong>,\u00a0Ubuntu<\/strong>\u00a0and\u00a0Linux Mint<\/strong>.<\/p>\n

Make sure that your repository enabled and available to install\u00a0Shellinabox<\/strong>\u00a0from the that repository. To check, do a search for\u00a0Shellinabox<\/strong>\u00a0with the \u201capt-cache<\/strong>\u201d command and then install it using \u201capt-get<\/strong>\u201d command. `<\/p>\n

On Debian, Ubuntu and Linux Mint<\/h5>\n
$ sudo apt-cache search shellinabox\r\n$ sudo apt-get install openssl shellinabox<\/pre>\n
On RHEL, CentOS and Fedora<\/h5>\n
On\u00a0Red Hat<\/strong>\u00a0based distributions, you need to first have\u00a0enable EPEL repository<\/a>\u00a0and then install it using the following \u201cyum<\/strong>\u201d command. (Fedora<\/strong>\u00a0users don\u2019t need to enable\u00a0EPEL<\/strong>, it\u2019s already a part of\u00a0Fedora<\/strong>\u00a0project).<\/p>\n
# yum install openssl shellinabox<\/pre>\n
Configuring Shellinabox<\/h3>\n
By default,\u00a0shellinaboxd<\/strong>\u00a0listens on\u00a0TCP<\/strong>\u00a0port\u00a04200<\/strong>\u00a0on\u00a0localhost<\/strong>. For security reason, I change this default port to a random (i.e.\u00a06175<\/strong>) to make it difficult for anyone to reach your\u00a0SSH<\/strong>\u00a0box. Also, during installation a new self-signed\u00a0SSL<\/strong>\u00a0certificate automatically created under \u201c\/var\/lib\/shellinabox<\/strong>\u201d to use\u00a0HTTPS<\/strong>\u00a0protocol.<\/p>\n
On Debian, Ubuntu and Linux Mint<\/h5>\n
$ sudo vi \/etc\/default\/shellinabox<\/pre>\n
# TCP port that shellinboxd's webserver listens on\r\nSHELLINABOX_PORT=6175\r\n\r\n# specify the IP address of a destination SSH server\r\nSHELLINABOX_ARGS=\"--o-beep -s \/:SSH:172.16.25.125\"\r\n\r\n# if you want to restrict access to shellinaboxd from localhost only\r\nSHELLINABOX_ARGS=\"--o-beep -s \/:SSH:172.16.25.125 --localhost-only\"<\/pre>\n
On RHEL, CentOS and Fedora<\/h5>\n
# vi \/etc\/sysconfig\/shellinaboxd<\/pre>\n
# TCP port that shellinboxd's webserver listens on\r\nPORT=6175\r\n\r\n# specify the IP address of a destination SSH server\r\nOPTS=\"-s \/:SSH:172.16.25.125\"\r\n\r\n# if you want to restrict access to shellinaboxd from localhost only\r\nOPTS=\"-s \/:SSH:172.16.25.125 --localhost-only\"<\/pre>\n
Starting Shellinabox<\/h3>\n
Once you\u2019ve done with the configuration, you can start the service by issuing following command.<\/p>\n
On Debian, Ubuntu and Linux Mint<\/h5>\n
$ sudo service shellinaboxd start<\/pre>\n
On RHEL and CentOS<\/h5>\n
# service shellinaboxd start<\/pre>\n
On Fedora<\/h5>\n
# systemctl enable shellinaboxd.service\r\n# systemctl start shellinaboxd.service<\/pre>\n
Verify Shellinabox<\/h3>\n
Now let\u2019s verify whether\u00a0Shellinabox<\/strong>\u00a0is running on port\u00a06175<\/strong>\u00a0using \u201cnetstat<\/strong>\u201d command.<\/p>\n
$ sudo netstat -nap | grep shellinabox\r\nor\r\n# netstat -nap | grep shellinabox<\/pre>\n
tcp        0      0 0.0.0.0:6175            0.0.0.0:*               LISTEN      12274\/shellinaboxd<\/pre>\n
Now open up your web browser, and navigate to\u00a0https:\/\/Your-IP-Adress:6175<\/strong>. You should be able to see a web-based\u00a0SSH terminal<\/strong>. Login using your\u00a0username<\/strong>\u00a0and\u00a0password<\/strong>\u00a0and you should be presented with your shell prompt.<\/p>\n

Make sure you secure you\u00a0shellinabox<\/strong>\u00a0on\u00a0firewall<\/strong>\u00a0and open\u00a06175<\/strong>\u00a0port for specific\u00a0IP Address<\/strong>\u00a0to access your Linux shell remotely.<\/p>\n
