This is just a couple short utilities for doing a few cool things with shellinabox. This is set up using tmux or byobu to provide for a persistent session that will survive browser reloading and such.
This gives you a couple features, such as being able to log in to the same shell from another location (such as via ssh), controlling which applications are accessible, and being able to lauch multiple applications into the same virtual terminal window via html buttons. Look at tmux's "sendkeys" if you want to have html buttons type specific values rather than launch commands.
This works by having shellinabox run a backend script "installcmd" that is in charge of what is actually run in the shellinabox window. I have apache set to forward URLs to shellinabox so that port #s are not required and everything can run under the default web port. Apache proxy file and shellinabox start-up files are included.
Please see the Screenshot to see what's going on. The shell window and the html-embedded shell are connected. Each has a "shell" and "disk" tabs open. These are opened by clicking the buttons on the left of the shell. If either switches to the same tab as the other, then both screens update simultaneously until you switch to the other.
ScreenShot256.jpg shows typing in both windows (need not be on the same machine). And shows the mixdown from 256 colors to 16.
The backend is versioned (just in case) and so your URLs should be of the format of ...
/shell/?0.1&command
... version & command to run
The command to run must be configured in the installcmd backend which is currently in /root/bin, but feel free to adjust the shellinabox start-up to look for it elsewhere.
SECURITY WARNING: This was set up for a web-based installer that assumes a single user with root access. You should change this to a specific user or pass userinformation along (.htaccess) through the environment and have the back-end script use "su" to run the command as the correct user. Regular shells can be run with "login". You'll also want to change the "session" name from "Draven" to whatever the user has logged in as.
