Wetty = Web + tty

Terminal over HTTP and HTTPS. Wetty is an alternative to ajaxterm/anyterm but much better than them because wetty uses ChromeOS' terminal emulator (hterm) which is a full fledged implementation of terminal emulation written entirely in Javascript. Also it uses websockets instead of Ajax and hence better response time.

hterm source - https://chromium.googlesource.com/apps/libapps/+/master/hterm/

This fork has a few of the open PR's from the original merged in as well as scripts to make running in docker better.

Install

• git clone https://github.com/butlerx/wetty
• cd wetty
• yarn

Run on HTTP

node app.js -p 3000

If you run it as root it will launch /bin/login (where you can specify the user name), else it will launch ssh and connect by default to localhost.

If instead you wish to connect to a remote host you can specify the --sshhost option, the SSH port using the --sshport option and the SSH user using the --sshuser option.

You can also specify the SSH user name in the address bar like this:

http://yourserver:3000/wetty/ssh/<username>

Run on HTTPS

Always use HTTPS. If you don't have SSL certificates from a CA you can create a self signed certificate using this command:

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 30000 -nodes

And then run:

node app.js --sslkey key.pem --sslcert cert.pem -p 3000

Again, if you run it as root it will launch /bin/login, else it will launch SSH to localhost or a specified host as explained above.

Run wetty behind nginx

Put the following configuration in nginx's conf:

location /wetty {
  proxy_pass http://127.0.0.1:3000/wetty;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  proxy_read_timeout 43200000;

  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $http_host;
  proxy_set_header X-NginX-Proxy true;
}

If you are running app.js as root and have an Nginx proxy you have to use:

http://yourserver.com/wetty

Else if you are running app.js as a regular user you have to use:

http://yourserver.com/wetty/ssh/<username>

Note that if your Nginx is configured for HTTPS you should run wetty without SSL.

Dockerized Version

This repo includes a Dockerfile you can use to run a Dockerized version of wetty. You can run whatever you want!

Just modify docker-compose and run:

docker-compose up -d

Visit the appropriate URL in your browser ([localhost|$(boot2docker ip)]:PORT).

The default username is term and the password is term, if you did not modify SSHHOST

If you dont want to build the image yourself just remove the line build; .

Run wetty as a service daemon

Install wetty globally with -g option:

    $ sudo npm install wetty -g
    $ sudo cp /usr/local/lib/node_modules/wetty/bin/wetty.conf /etc/init
    $ sudo start wetty

This will start wetty on port 3000. If you want to change the port or redirect stdout/stderr you should change the last line in wetty.conf file, something like this:

exec sudo -u root wetty -p 80 >> /var/log/wetty.log 2>&1

Clean-up

If users dont fully disconnect when finished ssh connections will actually be kept open the simplest way to deal with this is run /app/bin/cleanup on a cron job.
