+Q) When I try to run sudo via ssh, I get the error:
+ sudo: no tty present and no askpass program specified
+A) ssh does not allocate a tty by default when running a remote command.
+ Without a tty, sudo cannot disable echo when prompting for a password.
+ You can use ssh's "-t" option to force it to allocate a tty.
+ Alternately, if you do not mind your password being echoed to the
+ screen, you can use the "visiblepw" sudoers option to allow this.
