echo to etc file
Hi there.

I would like to add a mount line to a cluster of mini servers, quite a few of them. I need to do this remotely with pssh.

The problem being ssh sudo echo snd ssh sudo fprint both produce permission denied. I know sudo echo works locally, so it's quite rightly prevented over ssh. This isn't a password problem as I have copied shared keys.

So, the question is, how can I do this quite wrongly using ssh? (!)
I can only use pssh, I could use a script if I can take an ip list from file, or I could use python. I cannot add any software to the nodes. Or at least I really don't want to.

Many thanks.

Just thought I'd try pssh <ops> "sudo chmod 0777 /etc/fstab" worked fine, then I could echo the mount line.

So, there you go!

gnome-ssh-askpass

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

NAME

       gnome-ssh-askpass - prompts a user for a passphrase using GNOME

SYNOPSIS

       gnome-ssh-askpass

DESCRIPTION

       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 automatically 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, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass.

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 using gdk_pointer_grab() before asking for a passphrase.

       Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab().

AUTHOR

       This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others).  It was based on that
