Well, because of the firmware, though it is unix based, it requires that you specify a user in the cron file.
Check it out here: http://www.dd-wrt.com/wiki/index.php/CRON (Darn thing won't let me post real URLs yet)

That been my holy book for this project.

I think you might be right about the PATH thing. (I also have a theory that something with the quotes is messing it up) Whatever it is, I realized ssh doesn't output when run from cron. With that being said:

I actually managed to get some sort of workaround that does just fine.

- I made a script on the remote machine that does the query and then outputs the code to a file named 'codelog'
- The script on the router runs, sshes, and executes the script on the remote machine
- Then, the script runs 'scp' to copy the 'codelog' file from the remote machine to the router
- Finally, I set the output of 'cat codelog' as my variable.
- And well, it works!


Thanks so much!

xon

xon(1X) 																   xon(1X)

NAME

       xon - start an X program on a remote machine

SYNOPSIS

       xon remote-host [-access] [-debug] [-name window-name] [-nols] [-screen screen-no] [-user user-name] [command...]

OPTIONS

       Note  that  the options follow the remote host name (as they do with rlogin).  Runs xhost locally to add the remote host to the host access
       list in the X server.  This will not work unless xhost is given permission to modify the access list.  Normally, xon disconnects the remote
       process	from  stdin,  stdout  and  stderr to eliminate the daemon processes which usually connect them across the network.  Specifying the
       -debug option leaves them connected so that error messages from the remote execution are sent back to the originating host.  This specifies
       a  different  application  name	and window title for the default command (xterm).  Normally xon passes the -ls option to the remote xterm;
       this option suspends that behaviour.  This changes the screen number of the DISPLAY variable passed to the remote command.  By default, xon
       simply  uses  rsh/remsh/rcmd  to  connect to the remote machine using the same user name as on the local machine.  This option cause xon to
       specify an alternative user name.  This will not work unless you have authorization to access the remote account, by placing an appropriate
       entry in the remote users file.

DESCRIPTION

       The  xon  program  runs the specified command (default xterm -ls) on the remote machine using rsh, remsh, or rcmd.  xon passes the DISPLAY,
       XAUTHORITY and XUSERFILESEARCHPATH environment variables to the remote command.

       When no command is specified, xon runs 'xterm -ls'.  It additionally specifies the application name to be 'xterm-remote-host' and the  win-
       dow title to be 'remote-host'.

       xon can only work when the remote host will allow you to log in without a password, by having an entry in the file permitting access.

BUGS

       xon can get easily confused when the remote-host, user-name or various environment variable values contain white space.

       xon has no way to send the appropriate X authorization information to the remote host.
