How can the output of one users xterm be directed to the other user so that you can easily allow someone to see what you are doing?


Back in early 2005, someone at work was helping me troubleshoot a problem and he somehow directed his output onto my xterm. All he asked for was my IP address. I don't know if the output was also being displayed for him or not. Around that time, I went overseas on a 2 year assignment. When I got back early last year, I went to the only two people I could think of that I might have been working with back in 2005 and asked them about this. Both said it wasn't them and they didn't know how to do it. I have played around with it a little but have not been able to make it work and I find that it would be pretty useful.

Has anyone here done this, or know how to do it?
I'm the product manager for SecureCRT and there's an undocumented feature in SecureCRT 6.0 and later that allows you to do this. Here are the steps:
  1. In SecureCRT, open the Session Options dialog for the dialog that you want to allow someone else to monitor.
  2. Go to the "Mapped Keys" category and click the "Map a Key" button. For the Function, select "SSH Function" and for the SSH Function, select "TOGGLE_MONITOR_SERVER".
  3. Connect to the session. When you want to let someone else monitor the session, press the mapped key you selected in step 2. The first time you do this, you will need to generate a public key. A dialog will be displayed that allows you to specify the information that will be needed by the person who will be monitoring the session.
  4. Give the other person the information from the dialog in step 3. When they connect, you will see a message in SecureCRT that they are connected. They will then be able to see everything in your SecureCRT session.
  5. To end the monitoring session, you can press the mapped key again to terminate the server monitor, have the other person log out, or disconnect your session in SecureCRT.
The session being monitored can use any protocol, but the session doing the monitoring must use SSH2. If you try it, I'd be interested in any feedback you have about this feature.

xgetdefault

XGetDefault()															     XGetDefault()

Name
  XGetDefault - extract an option value from the resource database.

Synopsis
  char *XGetDefault(display, program, option)
	Display *display;
	char *program;
	char *option;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDisplay().

  program  Specifies  the program name to be looked for in the resource database.  The program name is usually argv[0], the first argument on
	   the UNIX command line.

  option   Specifies the option name or keyword.  Lines containing both the program name and the option name, separated only by a  period  or
	   asterisk, will be matched.

Returns
  The resource value.

Description
  XGetDefault() returns a character string containing the user's default value for the specified program name and option name.	XGetDefault()
  returns NULL if no key can be found that matches option and program.	For a description of the matching rules, see XrmGetResource().

  The strings returned by XGetDefault() are owned by Xlib and should not be modified or freed by the client.

  Lines in the user's resource database look like this:

      xterm.foreground: 	 #c0c0ff
      xterm.geometry:		 =81x28
      xterm.saveLines:		 256
      xterm.font:		 8x13
      xterm.keyMapFile: 	 /usr/black/.keymap
      xterm.activeIcon: 	 on
      xmh.header.font		 9x15

  The portion on the left is known as a key; the portion on the right is the value.  Uppercase or lowercase is important in keys.   The  con-
  vention is to capitalize only the second and successive words in each option, if any.

  Resource  specifications are usually loaded into the XA_RESOURCE_MANAGER property on the root window at login.  If no such property exists,
  a resource file in the user's home directory is loaded.  On a UNIX-based system,  this  file	is  $HOME/.Xdefaults.	After  loading	these
  defaults, XGetDefault() merges additional defaults specified by the XENVIRONMENT environment variable.  If XENVIRONMENT is defined, it con-
  tains a full path name for the additional resource file.  If XENVIRONMENT is not defined, XGetDefault()  looks  for  $HOME/.Xdefaults-name,
  where  name specifies the name of the machine on which the application is running. If length of ".Xdefaults-name" is greater than 255, then
  $HOME/.Xdefaults-IP address is looked for instead, where IP address is the internet address of the host.

  The first invocation of XGetDefault() reads and merges the various resource files into Xlib so that subsequent requests are  fast.   There-
  fore, changes to the resource files from the program will not be felt until the next invocation of the application.
