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!

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)
