Q:

Need a Browser Based SSH Terminal Client -- WordPress Plugin?

I have a network of about 150 users who need to reserve instruments daily using our custom Perl script on a Solaris signup computer that is accessed using an SSH client like Putty. This is a pain point for our users and I wish for them to be able to access the signup computer directly through our webpage without having to download Putty or a plugin for their browser. Is there a server side terminal SSH plugin that preferably can be installed through WordPress that will accomplish this task?
Ideally what I would like is to see the terminal open in a small window or tab of the browser. Prefer professionally maintained and supported softwares vs. free unsupported software.

A:

You can try https://github.com/billchurch/WebSSH2 It is not a WordPress plugin. It uses socket.io xterm.js and express so you will have to install some applications on the  server-side. 
Another option is https://github.com/chjj/tty.js/ TTY.js, created using node.js and socket.io
Another option is this HTML5 terminal. It also uses no Browser plugins: https://github.com/liftoff/GateOne It is written in Python  
Also if you would like to build your own ssh client, by communicating with your server you can use jQuery terminal: https://terminal.jcubic.pl/
