BIG-IP Notes

The attached BIG-IP-ILX-WebSSH2-20170821-0.1.2.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.

Instructions for deploying on a BIG-IP may be found at: https://github.com/billchurch/WebSSH2/wiki/Deploying-to-a-BIG-IP-running-12.1-or-13.0

Updated socket.io to 1.7.4

Added

• serverlog.client and serverlog.server options added to config.json to enable logging of client commands to server log (only client portion implemented at this time)
• morgan express middleware for logging

Changed

• Updated socket.io to 1.7.4
• continued refactoring, breaking up index.js
• revised error handling methods
• revised session termination methods

Removed

• color console decorations from util/index.js (no longer used)
• SanatizeHeaders function from util/index.js (no longer used)

Big Release

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.

Fixed terminal auto width, added experimental client-side logging.

Terminal geometry now properly fills the browser screen and communicates this to the ssh session. Tested with IE 11 and recent versions of Chrome/Safari/Firefox.

Added experimental support for logging (see Readme)

Update to Xterm.js 2.4.0 and set default terminal to xterm-color

Update to Xterm.js 2.4.0 and set default terminal to xterm-color

v0.0.3 - Updates xterm to 2.3.0 and bug fixes

• Fixes #7
• Update xterm to latest (2.3.0)

v0.0.2 - Move to xterm.js
