  • Snyk, Bithound, Travis CI
  • Cross platform improvements (path mappings)
  • Session fixup between Express and Socket.io
  • Session secret settings in config.json
  • env variable DEBUG=ssh2 will put the ssh2 module into debug mode

  • validation for host (v4,v6,fqdn,hostname), port (integer 2-65535), and header (sanitized) from URL input

Changed

  • error handling in public/client.js
  • moved socket.io operations to their own file /socket/index.js, more changes like this to come (./socket/index.js)
  • all session based variables are now under the req.session.ssh property or socket.request.ssh (./index.js)
  • moved SSH algorithms to config.json and defined as a session variable (..session.ssh.algorithms) -- prep for future feature to define algorithms in header or some other method to enable separate ciphers per host
  • minified and combined all js files to a single js in ./public/webssh2.min.js also included a sourcemap ./public/webssh2.min.js which maps to ./public/webssh2.js for easier troubleshooting.
  • combined all css files to a single css in ./public/webssh2.css
  • minified all css files to a single css in ./public/webssh2.min.css
  • copied all unmodified source css and js to /public/src/css and /public/src/js respectively (for troubleshooting/etc)
  • sourcemaps of all minified code (in /public/src and /public/src/js)
  • renamed client.htm to client-full.htm
  • created client-min.htm to serve minified javascript
  • if header.text is null in config.json and header is not defined as a get parameter the Header will not be displayed. Both of these must be null / undefined and not specified as get parameters.

Fixed

  • Multiple errors may overwrite status bar which would cause confusion as to what originally caused the error. Example, ssh server disconnects which prompts a cascade of events (conn.on('end'), socket.on('disconnect'), conn.on('close')) and the original reason (conn.on('end')) would be lost and the user would erroneously receive a WEBSOCKET error as the last event to fire would be the websocket connection closing from the app.
  • ensure ssh session is closed when a browser disconnects from the websocket
  • if headerBackground is changed, status background is changed to the same color (typo, fixed)

Removed

  • Express Static References directly to module source directories due to concatenating and minifying js/css
