Here is an answer I submitted yesterday. This is a cut&paste of that answer.
The application is different but the functions of what you are looking for are the same.
HIH


For the 'no tty present', open up your sudoers file and look for a line that says
Quote:
Defaults requiretty
Change it so the requiretty has the negate character in front. Make it look like
Quote:
Defaults !requiretty
Notice the exclamation (negate) character in front of the requiretty

I'm confused by the code you are using
ssh musedeploy@${SERVER} ${PSWD} || die "Deployment failed"That looks like you are just trying to login to $SERVER as the user musedeploy and the failure is on the passwd. Does this account execute something on login?

Your sudo entry, is that on the $SERVER or is that on the local system? If you are wanting to execute the command on $SERVER then put the entry into the sudoers on $SERVER. You may want to setup passwd-less login for ssh as well.

With the !requiretty and the sudoers entry on $SERVER you could try your command as such:

Code:
 ssh musedeploy@${SERVER} 'sudo $MUSE_CMD'

As you have NOPASSWD in the sudoers there is no need to worry about that.

The MUSE_CMD sudoers entry, is that suppose to be a single command or are they a string of separate commands? It appears you have multiple individual commands, they are not executing in succession. Is that what you are trying for?

SSH-ASKPASS-FULLSCREEN(1)				      General Commands Manual					 SSH-ASKPASS-FULLSCREEN(1)

NAME
ssh-askpass-fullscreen - A simple replacement for ssh-askpass written with gtk2 SYNOPSIS
ssh-askpass-fullscreen DESCRIPTION
This manual page was written for the Debian distribution because the original program does not have a manual page. gnome-ssh-askpass is a GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not invoked directly. It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display is available). This happens auto-matically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro- grams, for example. In order to be called automatically by ssh-add, ssh-askpass-fullscreen should be installed as /usr/bin/ssh-askpass ssh-askpass-fullscreen is a program that... ENVIRONMENT VARIABLES
The following environment variables are recognized: GNOME_SSH_ASKPASS_GRAB_SERVER Causes gnome-ssh-askpass to grab the X server before asking for a passphrase. GNOME_SSH_ASKPASS_GRAB_POINTER Causes gnome-ssh-askpass to grab the mouse pointer will be grabbed too. These may have some benefit to security if you don't trust your X server. Keyboard is always grabbed. SEE ALSO ssh-add(1), ssh-askpass(1). AUTHOR
This manual page was written by Marco Presi (Zufus) <zufus@debian.org>, for the Debian GNU/Linux system (but may be used by others) and it is based on that for x11-ssh-askpass by Philip Hands and the one for gnome-ssh-askpass by Colin Watson <cjwatson@debian.org> May 8 , 2004 SSH-ASKPASS-FULLSCREEN(1)
