Linux Shell Web HyperTerminal tool shellinabox

Shell is a Linux kernel application, which refers to the software that "provides the user with an operating interface". It is also a command parser, which is similar to the cmd.exe application under the Windows operating system DOS. It receives user commands and then invokes corresponding applications. Users are generally accustomed to using client-side tools such as putty, Xshell, SecureCRT, secure shell and so on, but these clients need to be installed locally before they can be used. If you change to other computers, you also need to reinstall, which is very troublesome to use, so today we are going to introduce a very convenient shell client tool. Use the browser that comes with the system to manage the Linux service terminal, which can be managed on any terminal at any time. This tool shellinabox, which runs under linux, only needs to install and configure shellinabox on the Linux server.

Shellinabox is a Web-based terminal simulator created by Markus Gutschke. It has a built-in Shell Web server, runs as a Web-based SSH client on a designated port, and prompts you to use any browser that supports AJAX/JavaScript and CSS to remotely access and control Linux Server SSH Shell without any other browser plug-ins. It is very convenient to use, but a little bit of Linux foundation is required for installation and configuration. If you feel that you do not understand Linux at all, you can suggest to buy the tutorial "Linux should learn this way". Very suitable for beginners, or go to the official website of this course to view detailed information, directly enter the title of this book in Baidu can directly enter the official website.

Shellinbox is a basic web ssh client with a built-in web server under the Linux server, which allows you to access the ssh shell of the linux server through a specified port, as long as your browser supports AJAX/JS/CSS, but now the browsers of the mainstream operating systems all support it. Shellinabox is an open source lightweight software, so before installing shellinabox, make sure whether the Linux server has openssl libraries installed. Debian and ubuntu officially provide deb installation package, while centos also has rpm package, which can also be installed through yum source, and installation and configuration are relatively simple. Let's install and configure shellinabox in detail below.

1. The steps of installation and configuration on RHEL and CentOS systems are as follows

# yum install openssl shellinabox

2. Configure shellinaboxd

192.168.3.160 is the IP address of the SSH server

# vim / etc/sysconfig/shellinaboxd

# TCP port that shellinboxd's webserver listens on

PORT=6175

# specify the IP address of a destination SSH server

OPTS= "- s /: SSH:192.168.3.160" # (https protocol)

# OPTS= "- t-s /: SSH:192.168.3.160" # (http protocol)

# if you want to restrict access to shellinaboxd from localhost only

# the following configuration is for host access only, but not for other hosts

# OPTS= "- s /: SSH:192.168.3.160-- localhost-only"

The default port of shellinaboxd is: 4200, which I changed to 6175.

You can also add the-p parameter at startup to save the process pid to the specified file, read it and kill it when you need to close

4. Check the service status

# netstat-nap | grep shellinabox

Tcp 0 0 0.0.0 0 6175 0.0.0 0 V * LISTEN 118916/shellinaboxd

Https://192.168.3.160:6175/

Automatically disconnect if you don't log in for 60s by default
