WebSSH
Introduction
A simple web application to be used as an ssh client to connect to your ssh servers. It is written in Python, base on tornado, paramiko and xterm.js.
Features
- SSH password authentication supported, including empty password.
- SSH public-key authentication supported, including DSA RSA ECDSA Ed25519 keys.
- Encrypted keys supported.
- Two-Factor Authentication (time-based one-time password) supported.
- Fullscreen terminal supported.
- Terminal window resizable.
- Auto detect the ssh server's default encoding.
- Modern browsers including Chrome, Firefox, Safari, Edge, Opera supported.

How it works
+---------+ http +--------+ ssh +-----------+
| browser | <==========> | webssh | <=======> | ssh server|
+---------+ websocket +--------+ ssh +-----------+
Requirements
- Python 3.8+
Quickstart
- Install this app, run command
pip install webssh
- Start a webserver, run command
wssh
- Open your browser, navigate to
127.0.0.1:8888
- Input your data, submit the form.
Server options
# start a http server with specified listen address and listen port
wssh --address='2.2.2.2' --port=8000
# start a https server, certfile and keyfile must be passed
wssh --certfile='/path/to/cert.crt' --keyfile='/path/to/cert.key'
# missing host key policy
wssh --policy=reject
# logging level
wssh --logging=debug
# log to file
wssh --log-file-prefix=main.log
# more options
wssh --help
Browser console
// connect to your ssh server
wssh.connect(hostname, port, username, password, privatekey, passphrase, totp);
// pass an object to wssh.connect
var opts = {
hostname: 'hostname',
port: 'port',
username: 'username',
password: 'password',
privatekey: 'the private key text',
passphrase: 'passphrase',
totp: 'totp'
};
wssh.connect(opts);
// without an argument, wssh will use the form data to connect
wssh.connect();
// set a new encoding for client to use
wssh.set_encoding(encoding);
// reset encoding to use the default one
wssh.reset_encoding();
// send a command to the server
wssh.send('ls -l');
Custom Font
To use custom font, put your font file in the directory webssh/static/css/fonts/
and restart the server.
URL Arguments
Support passing arguments by url (query or fragment) like following examples:
Passing form data (password must be encoded in base64, privatekey not supported)
http://localhost:8888/?hostname=xx&username=yy&password=str_base64_encoded
Passing a terminal background color
http://localhost:8888/#bgcolor=green
Passing a terminal font color
http://localhost:8888/#fontcolor=red
Passing a user defined title
http://localhost:8888/?title=my-ssh-server
Passing an encoding
http://localhost:8888/#encoding=gbk
Passing a font size
http://localhost:8888/#fontsize=24
Passing a command executed right after login
http://localhost:8888/?command=pwd
Passing a terminal type
http://localhost:8888/?term=xterm-256color
Use Docker
Start up the app
docker-compose up
Tear down the app
docker-compose down
Tests
Requirements
pip install pytest pytest-cov codecov flake8 mock
Use unittest to run all tests
python -m unittest discover tests
Use pytest to run all tests
python -m pytest tests
Deployment
Running behind an Nginx server
wssh --address='127.0.0.1' --port=8888 --policy=reject
# Nginx config example
location / {
proxy_pass http://127.0.0.1:8888;
proxy_http_version 1.1;
proxy_read_timeout 300;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-PORT $remote_port;
}
Running as a standalone server
wssh --port=8080 --sslport=4433 --certfile='cert.crt' --keyfile='cert.key' --xheaders=False --policy=reject
Tips
- For whatever deployment choice you choose, don't forget to enable SSL.
- By default plain http requests from a public network will be either redirected or blocked and being redirected takes precedence over being blocked.
- Try to use reject policy as the missing host key policy along with your verified known_hosts, this will prevent man-in-the-middle attacks. The idea is that it checks the system host keys file("~/.ssh/known_hosts") and the application host keys file("./known_hosts") in order, if the ssh server's hostname is not found or the key is not matched, the connection will be aborted.
