conspy - virtual console spy tool
conspy [ options ] [ console ]
Conspy allows the user to take control of a Linux virtual console. The user can see what is displayed on the console and their keystrokes are sent to it.
To exit from conspy press the escape key three times in quick succession.
- -g COLSxROWS, --geometry COLSxROWS
- Specify the console size. Conspy can almost always correctly guess the size so this is only useful when it complains it can't.
- -V, --version
- Print the program's version and exit.
- -v, --viewonly
- Don't send keystrokes to the virtual console.
- If supplied, console must be a number in the range 1 .. 63, corresponding to the virtual console device /dev/tty1 .. /dev/tty63. If not supplied the currently active virtual console is opened and tracked.
Conspy will not pass keystrokes to a virtual console whose keyboard is configured to send scan codes. X configures its keyboard like this. If the terminal does not have at least 64 colours no colour will be displayed. Conspy ignores the mouse. Conspy may display some non-ASCII characters incorrectly.
The kernel reports the console geometry and cursor position using bytes which limits both to 255 maximum. Conspy can usually guess the correct display size from the truncated version, but if the cursor position is beyond line 255 or column 255 conspy will put it in the wrong place.
Conspy depends on terminfo and curses working correctly for your terminal, and sometimes they don't. Konsole is/was one example of where they don't. Typing control-L will redraw the screen, which usually fixes the mess created. It also sends a control-L to the virtual console, of course.
- /dev/ttyX, /dev/vc/X
- The characters typed are sent to this device. The latter is for devfs. It is only used if the former does not exist.
- /dev/vcsaX, /dev/vcc/aX
- The display of the virtual console is read from here. The latter is for devfs. It is only used if the former does not exist.
