Use ssh keys <div class="gmail_quote">On Fri, Nov 6, 2009 at 3:46 PM, Colin Law <<a href="mailto:clanlaw@googlemail.com">clanlaw@googlemail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> I can shut down a remote machine by connecting via ssh then shutting it down ssh ip_address <logon messages> sudo shutdown -h now password: (entered pwd not visible) and the remote machine shuts down. To save typing (and brain power) I wrote a script on local machine ssh ip_addr sudo shutdown -h now When I run the script it works as expected and shuts down the remote machine, but when it prompts me for the password (for the sudo shutdown), the password I type is not hidden but is visible on screen, which is not good. I am sure there is a way round this but I have not managed to find it. Any help will be much appreciated.
