check out the file /etc/sudoers. u can add ure program and ure username . I dont remember what the syntax is but, u can read the man page for that. Its pretty simple . basically u can run the program with root priviliges but without having to become root. hope that helps. <div>On 9/2/05, Vincent Trouilliez <<a href="mailto:vincent.trouilliez@modulonet.fr">vincent.trouilliez@modulonet.fr</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I have got a programme that uses the parallel port of the machine. I added the module ppdev in /etc/modules so that the /dev/parport0 device gets created at boot so that the program can access the port. However I have to run the program as root in order to use the /dev/parport0, not very practical. How can I (permanently ie) allow user access to this device ? I would modify the permissions on the file, but since the device needs to be created at every boot, I also assume that it gets deleted at every power-off, and the user permissions with it sadly ! Is there a way ? Or will I have no choice but DIY and add a "chmod something /dev/parport0" in some start-up script in /etc/init.d ???
