Short Description
Terminal over HTTP and HTTPS.
Full Description

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

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

or

yarn add wetty.js

Run on HTTP

node bin/index.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>

or

http://yourserver:3000/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 bin/index.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 or apache

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;
}

Put the following configuration in apache's conf:

  RewriteCond %{REQUEST_URI}  ^/wetty/socket.io [NC]
  RewriteCond %{QUERY_STRING} transport=websocket [NC]
  RewriteRule /wetty/socket.io/(.*) ws://localhost:9123/wetty/socket.io/$1 [P,L]

  <LocationMatch ^/wetty/(.*)>
          DirectorySlash On
          Require all granted
          ProxyPassMatch http://127.0.0.1:9123
          ProxyPassReverse /wetty/
  </LocationMatch>

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

http://yourserver.com/wetty

Else if you are running bin/index.js as a regular user you can use:

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

or

http://yourserver.com/wetty

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 global option:

init.d

$ sudo yarn global add wetty.js
$ sudo cp /usr/local/lib/node_modules/wetty.js/bin/wetty.conf /etc/init
$ sudo start wetty

systemd

$ yarn global add wetty.js
$ cp ~/.config/yarn/global/node_modules/wetty.js/bin/wetty.service  ~/.config/systemd/user/
$ systemctl --user enable wetty
$ systemctl --user 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

FAQ

What browsers are supported?

Wetty supports all browsers that Google's hterm supports. Wetty has been reported to work on Google Chrome, Firefox and IE 11.

Why isn't Wetty working with IE?

This fix has been known to help some users.
