OSX Lion: ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory

I keep running into this.  For various reasons I need to use password-based authentication on some test boxes that are regularly rebuilt which makes using key based authentication difficult.

Ordinarily I set up an alias like this:

alias ssh1="sshpass -p secretpassword ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null"

… which lets me use a command like:

sshl eric@devbox

But sometimes (and I swear, it doesn’t always happen, but I haven’t figured out the variable yet), it fails, and I get:

ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory

… and indeed, the ssh-askpass binary doesn’t exist.  After some flailing around and googling, I finally came up with this ugly hack.  I create a shell script with the following contents:

#!/bin/bash
echo "secretpassword"

Then, I set the following environment variable, which directs sshpass to use my script instead of looking for the missing ssh-askpass

export SSH_ASKPASS=/Users/eric/scripts/ssh-askpass.sh

It’s ugly, but it works.  Of course, it assumes you’re always using the same “secretpassword”.  Some day I need to figure out a better way of addressing this, but today is not that day.
