Occasionally the LTSP client connected to my Lubuntu LTSP server won't PXE boot. There is a "No DHCP offers were received" sort of message on the client. I believe this is probably a power management issue that crops up sometimes when the server does not quite properly emerge from a sleep mode. On the server, from the command line I can interactively "sudo service isc-dhcp-server restart." But I would like to put that in a script for a user who know even less than I do. It's OK if the user has to enter the password to execute the command. I tried creating myscript.sh thus: #!/bin/bash sudo service isc-dhcp-server restart Then I ran "sudo chmod a+x myscript.sh" to make it executable by all. But when I run the script choosing either Execute or Execute in Terminal, I get no prompt for a password and it seems that the service restart command has not run. How can I do this? </body> </html>
