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.

Does not work on Firefox as hterm was written for ChromeOS. So works well on Chrome.
