How can I add myself to the uucp group? I have run this command "chmod 777 /dev/ttyUSB0". Is it correct?

one way is the shell command 'usermod', but most linux distros provide a GUI for user mgmt. by running chmod 777 you made the device file r/w/x accessible by everybody (including yourself) rather than adding yourself to the group that had/s permission to access the file (which is what usermod can do with the -G option). i suppose that if after chmod you still had problems, then the problem is not strictly a permission problem. -shane On Sat, 26 Aug 2006, Ming wrote: How can I add myself to the uucp group?

If you are using fedora, Changing permissions with the following (as root) will only remain accessable to other users as long as usb device is connected. If usb device is removed or pc reboots, all permissions are reset to root. chmod a=+xrw /dev/ttySO (if using serial) chmod a=+xrw /dev/ttyUSB0 (if using USB) www.jpilot.org/pipermail/jpilot/2005-July/005210.html explains how to edit udev rules such that permission can be set for all users. vi /etc/udev/rules.d/50-udev.rules change KERNEL=="ttyS*",GROUP="uucp", MODE="0666" to KERNEL=="ttyS*",GROUP="uucp", MODE="0660" and the same for KERNEL=="ttyUSB*", GROUP="uucp", MODE="0666" NOTE: I dont know what security risks there are using these permissions. hope this helps, Cormac On Sat, 2006-08-26 at 12:49 +0800, Lau Ming Leong wrote: > How can I add myself to the uucp group?
