[ilugd] Ubuntu sudo command problem
Hi All, Today i changed the permission of my /etc directory and it's sub directories and files using sudo nautilus. And now my everything including servers and all have stopped working. When i type sudo anywhere to use it shows an error as - sudo: /etc/sudoers is mode 0446, should be 0440 sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin Can somebody help me to get my system back as it was earlier.. Or is there any way to restore my system back? Thanks in advance... -- Regards RAKESH KUMAR ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

You should know what you're doing particularly when fiddling with the system files and, or directories. When i type sudo anywhere to use it shows an error as - sudo: /etc/sudoers is mode 0446, should be 0440 sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin Can somebody help me to get my system back as it was earlier.. Or is there any way to restore my system back? You did not tell what was the exact command or what indeed you typed, hence all I can do is just guess or provide you a hint. Try booting your system with a live/rescue CD/DVD and executing the following: $ sudo mount /dev/partition /mnt $ sudo chmod -R o-w /mnt/etc Substitute the partition with root partition of your Ubuntu installation. WARNING: The above is also as dangerous as was your attempt to make your system unusable. NOTE: All directories in your /etc including /etc should/can be 0555 or 0755 and the files 0444 or 644, but some sensitive directories and, or files containing passwords or serious things should/must not even be readable by others i.e. these directories should/must be 0550 or 0750 and files 0440 or 0640. Reboot your system; hope that helps. -- Balwinder S bdheeman Dheeman (http://werc.homelinux.net/contact/) ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

Or is there any way to restore my system back? 1. Get a list of permissions of critical files in /etc/ from the 'net, a friend's machine, wherever. 2. Boot into root. I won't tell you how, there are enough pointers on the 'net. 3. Apply the correct permissions to your own /etc files. 4. Reboot. 5. Pay me.
