set environment variable SSH_ASKPASS or askpass in sudoers, resp

debian, environment-variables, openssh, ssh

Solution

There are two ways to get rid of this error message. The easy way is to provide a pseudo terminal for the remote sudo process. You can do this with the option `-t`:

ssh -t user@domain.com 'sudo echo "foobar"'

Problem

I'm trying to login to a ssh server and to execute something like: ``` ssh user@domain.com 'sudo echo "foobar"' ``` Unfortunately I'm getting an error: ``` sudo: no tty present and no askpass program specified ``` Google told me to either set the environment variable `SSH_ASKPASS` or to set `askpass` in the `sudoers` file. My remote machine is running on Debian 6 and I've installed the packages ssh-askpass and ssh-askpass-gnome and my `sudoers` file looks like this: ``` Defaults env_reset Defaults askpass=/usr/bin/ssh-askpass # User privilege specification root ALL=(ALL) ALL user ALL=(ALL) ALL ``` Can someone tell what I'm doing wrong and how to do it better.
