0.1.0

A lot of refactoring has happened. More to come. Made some pretty major changes all around so figured this was worth incrementing the minor version number. Changes outlined below.

Added

  • ChangeLog.md file
  • Support for UTF-8 characters (thanks @bara666)
  • Snyk, Bithound, Travis CI for code quality
  • 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
  • env variable DEBUG=WebSSH2 will output additional debug messages for functions
    and events in the application (not including the ssh2 module debug)
  • using Grunt to pull js and css source files from other modules npm run build to rebuild these if changed or updated.
  • useminified option in config.json to enable using minified client side javascript (true) defaults to false (non-minified)
  • sshterm= query option to specify TERM environment variable for host, valid strings are alpha-numeric with a hyphen (validated). Otherwise the default ssh.term variable from config.json will be used.
  • 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
  • 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

BIG-IP Notes

The attached BIG-IP-ILX-WebSSH2-20170527-0.1.0.tgz file may be imported to as an iRulesLX Workspace on a BIG-IP v12.1+ with iRules LX provisioned.

iRulesLX streaming interface is not yet supported, so this will just run as a daemon essentially.
