Scripting ssh question

I am new here so I apologize if this question is in the wrong section or outside of the realm of this board. Also, this is just my first week into shell programming so I am probably doing lots of things wrong.

I am trying to write a script to ssh to a machine as one user and then run a command as another user on the remote machine. The problem (I think) I have been running into is that the second user on the remote machine must not have a password.

Here is my latest attempt at it:

Code:
echo "password" | sudo -S  su - user2 "command" user1@host

When I try this I get some error about not being able to execute the binary associated with whatever command I try.

I would really appreciate any help anyone can offer.

DEBCONF-SET-SELECTIONS(1)					      Debconf						 DEBCONF-SET-SELECTIONS(1)

NAME
debconf-set-selections - insert new default values into the debconf database SYNOPSIS
debconf-set-selections file debconf-get-selections | ssh newhost debconf-set-selections DESCRIPTION
debconf-set-selections can be used to pre-seed the debconf database with answers, or to change answers in the database. Each question will be marked as seen to prevent debconf from asking the question interactively. Reads from a file if a filename is given, otherwise from stdin. WARNING
Only use this command to seed debconf values for packages that will be or are installed. Otherwise you can end up with values in the database for uninstalled packages that will not go away, or with worse problems involving shared values. It is recommended that this only be used to seed the database if the originating machine has an identical install. DATA FORMAT
The data is a series of lines. Lines beginning with a # character are comments. Blank lines are ignored. All other lines set the value of one question, and should contain four values, each separated by one character of whitespace. The first value is the name of the package that owns the question. The second is the name of the question, the third value is the type of this question, and the fourth value (through the end of the line) is the value to use for the answer of the question. Alternatively, the third value can be "seen"; then the preseed line only controls whether the question is marked as seen in debconf's database. Note that preseeding a question's value defaults to marking that question as seen, so to override the default value without marking a question seen, you need two lines. Lines can be continued to the next line by ending them with a "" character. EXAMPLES
# Force debconf priority to critical. debconf debconf/priority select critical # Override default frontend to readline, but allow user to select. debconf debconf/frontend select readline debconf debconf/frontend seen false OPTIONS
--verbose, -v verbose output --checkonly, -c only check the input file format, do not save changes to database SEE ALSO
