wetty

Wetty = Web + tty. Terminal access in browser over http/https

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/

  • git clone https://github.com/krishnasrinivas/wetty

  • cd wetty

  • npm install

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>

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.

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.

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

Just do:

    docker run --name term -p 3000 -dt nathanleclaire/wetty

Visit the appropriate URL in your browser ([localhost|$(boot2docker ip)]:PORT).
The username is term and the password is term.

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
