Preview
Requirements
Python 2.7/3.4+
Quickstart
Install this app pip install webssh
Start a webserver wssh
Open your browser, navigate to 127.0.0.1:8888
Input your data, submit the form.
Installation options
Install from the pypi repository, may not the latest version
pip install webssh
Install from the github repository, always the latest version
pip install https://github.com/huashengdun/webssh/archive/master.zip
Server options
# listen address and port
wssh --address='0.0.0.0' --port=8000
# missing host key policy
wssh --policy=reject
# logging level
wssh --logging=debug
# log to file
wssh --log-file-prefix=main.log
# more options
wssh --helpUse console
// set a new encoding for client to use
wssh.set_encoding(encoding);
// reset encoding to use the default one
wssh.reset_encoding();
// connect to your ssh server
wssh.connect(hostname, port, username, password, privatekey);
// without argument, wssh will use the form data to connect
wssh.connect();
// define a mapping object
var opts = {
hostname: 'hostname',
port: 'port',
username: 'username',
password: 'password',
privatekey: 'the private key text'
};
wssh.connect(opts);
// send a command to the server
wssh.send('ls -l');Tests
Use unittest to run all tests
python -m unittest discover tests
Use pytest to run all tests
python -m pytest tests
An example of config for running this app behind an Nginx server
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;
}Tips
Try to use Nginx as a front web server (see config example above) and enable SSL, this will prevent your ssh credentials from being uncovered. Also afterwards the communication between your browser and the web server will be encrypted as they use secured websockets.
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.
