I use a USB keychain to store my OpenSSH keys that I use on Linux and my Mac. SSH always gripes about the damn file permissions so I just created a shell function to take care of the problem for me. I don't have it on hand, but it's something like:
sshforceadd() {
local rc=1
local file="$1"
if [ -n "$file" -a -f "$file" ] ; then
local bn=`basename "$file"`
touch /var/tmp/$bn
chmod 0600 /var/tmp/$bn
cat "$file" > /var/tmp/$bn
ssh-add /var/tmp/$bn ; rc=$?
rm -f /var/tmp/$bn
fi
return $rc
}
This way I don't have to worry about the mount permissions.
