About Gate One
Gate One is an HTML5 web-based terminal emulator and SSH client. Top features:
- No browser plugins required! Say goodbye to the security problems of Java, Flash, and ActiveX.
- Multi-user and multi-terminal: Hundreds of simultaneous users and terminals can be served from ho-hum hardware.
- Advanced terminal emulation including support for 256 colors, fancy text styles, and more.
- Supports capturing and displaying images and PDFs inline within terminals (see screenshots).
- Type in your native language! Gate One supports Unicode, international keyboard layouts, and localized strings (internationalization or i18n).
- Natural copy & paste: Highlight text and use your browser's native context menu. On Macs you can use ⌘-c and ⌘-v and on Linux desktops you can middle-click-to-paste. Shift-Insert works too!
- Terminal sessions can be resumed even if the browser is closed or disconnected. They can also be resumed from a completely different computer. You'll never have to worry about the office VPN disconnecting again!
- Supports server-side logging of user sessions via any combination of syslog, remote syslog, or directly to disk.
- Many authentication mechanisms are supported: Anonymous, Kerberos (Single Sign-On with Active Directory!), PAM, Google Auth, and there's an OpenID-like WebSocket API for applications embedding Gate One (see the chat app in the tests directory for an example of how it works).
- Gate One is easy to customize: Themes and plugins can add features or override just about anything. In fact, Gate One's SSH functionality is implemented entirely via a plugin.
- The Gate One server can be stopped & started without users losing their running terminal applications (even SSH sessions stay connected!).
- The SSH plugin allows users to duplicate sessions without having to re-enter their username and password (it re-uses the existing SSH tunnel). It also supports key-based authentication and includes an SSH identity manager that supports RSA, DSA, ECDSA, and even X.509 certificates.
- The Bookmarks plugin lets you keep track of all of your hosts with support for tagging, sorting, and includes a super fast search. It was built to handle thousands of bookmarks and can be used with whatever URLs you want--it isn't limited to SSH!
- The Logging plugin includes a Log Viewer that allows users to sort, view, and even export recordings of their terminal sessions to self-contained HTML files that can be shared. Demonstrating anything on the command line can be as simple as performing the task and clicking a button!
- The Playback plugin allows users to rewind and play back their connected terminal sessions in real-time, just like a video! This can be done via the playback controls or by holding the shift key while scrolling.
- The Convenience plugin adds many convenient capabilities:
- IPv4 and IPv6 addresses become clickable elements that can perform a reverse DNS lookup.
- The output of 'ls -l' is transformed into clickable elements that can perform user and group lookups, convert bytes into human-readable strings, and even tell you what the 'chmod equivalent' is of the permissions field (e.g. clicking on 'crw-rw-rw-' would tell you, "(Character Device) with permissions equivalent to 'chmod 0666'").
- Automatic syntax highlighting of syslog messages.
- The Example plugin demonstrates how to write your own plugins and shows off the SSH plugin's exec_remote_command() functionality.
- Gate One works with Python 2.6+, Python 3, and even pypy!
- The daemon that acts as the web server for Gate One is small and light enough to be included in embedded devices.

Other Notable Bits
Gate One's termio and terminal Python modules can be used together to automate, screen-scrape, and completely control terminal applications. The expect() function can be used as a replacement for pexpect that has some additional features and benefits:
- It can be used asynchronously: It won't block which means it is perfect for executing commands from a web application.
- It supports sophisticated decision trees and callbacks: You can completely re-define all patterns and callbacks on-the-fly based on whatever conditions you want.
