When I run '# sudo touch newfile' my expectation was that the file would be owned by me, not by root, as my understanding of sudo is that it is giving me, the user, root priviledges but does not actually switch the user.Do I have a fundamental misunderstanding of what sudo is about?

I am trying to edit limits.conf, changed file permissions:
sudo chmod limits.conf -rwxrwxrwx
But got this message:
"Could not save the file /etc/security/limits.conf. You are trying to save the file on a read-only disk. Please check that you typed the location correctly and try again."
I followed these instructions:
"copy - paste this code into terminal
gedit $HOME/.gnome2/nautilus-scripts/Open as root
copy-paste this text into that file and push 'save'
for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do
gnome-sudo "gnome-open $uri" &
done
now copy-paste this code into terminal
chmod +x $HOME/.gnome2/nautilus-scripts/Open as root
Now you can right click on the file you want to edit, select 'scripts' and say 'open as root' to let you modify it". [URL] the right click worked but the file didn't open.
I have a machine which has only /opt with some decent amount of space where I can install a software. /opt belongs to root:root. The software I want to install cannot be installed as root user.
So lets say I create a directory called /opt/install1 and then chown -R install1 to belong to user1. And now I install the software under /opt/install1 with user as user1.
Is this a best practice violation? There could potentially be just /opt/install1 belong to user1 and in future everything else created under /opt belonging to root..
Debugging some of my scripts after upgrading from Debian Lenny to Ubuntu 10.04. In so doing, I tripped over this "problem," the solution to which may give me a clue to others.
On a bash shell command line I created a file thusly:
sudo touch zero_file
and it lists as expected with default permissions 0644:
-rw-r--r-- 1 root root 0 2011-03-09 11:18 zero_file
But then this command fails
sudo echo abcdef >>zero_file
-bash: zero_file: Permission denied
I can place the command (minus the "sudo") in a script & run it under the auspices of sudo & it works. Am I missing something re the stdin redirection when using sudo?
I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?
EDIT: /etc/sudoers looks like:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
##Me
user1 ALL=(ALL) ALL
Being a system administrator i came across a statement as "Excluding temporary directories /tmp and /var/tmp, no root owned files should be in world writable directories"While the above statement may look straight forward but how would i check if there are any such directories in the distribution?

View 3 Replies View RelatedI was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

I reinstalled 9.10 yesterday and put the home folder on its own partition. Now it has my home folder as owned by me but all the files in it including Documents are owned by root. I did tell it to change ownership on enclosed files with no luck. So I can't paste my backup files into the Documents folder. I can do GKsudo nautilus but it times out every 15 minutes and I have to restart copying the 67GB of files constantly.

When I looked at the permissions of the other app icons, they were owned by me, the user.Why did plasma make my newly created app launcher owned by root?I'm so used to the way KDE 3 worked. It was so much simpler. I could click anywhere on that desktop to add shortcuts and they were owned by me, not root. I don't understand why they changed this.
View 9 Replies View RelatedI copied a folder from /media/memory_stick into a folder /opt/openerp/server/bin/addons.
Trying to open the copied folder I discovered that it is impossible because it is owned by root.I should like to delete the copied folder.To avoid this ownership I copied the folder in /home/cristian/Downloads and I will copy it with:sudo cp -R folder_name /opt/openerp/server/bin/addonsMaybe in this way the folder will be not more owned by root.I tried already but because in the destination folder already exist one owned by root nothing is happening.

View 1 Replies View RelatedOS views all USB drives as owned by 'root'. My internal 40 Gig drive files appear properly owned by 'glene77is'.My primary backup is a 320 Gig with all files now owned by 'root'.Using the filemanager "Nautilus", all USB external devices must be accessed as 'usb0', 'usb1','usb2', etc.The device names such as 'Alpha', 'Beta','Cappa' are not usably recognized in the menu options.Nautilus shows their names and the usb# as menu options for browing a device directory. Nautilus will open only the usb# menu option. Then sees all files as owned by 'root'.

View 1 Replies View RelatedI'm trying to mount some CIFS shares (NetApp) to my Ubuntu 11.04 desktop (64-bit).I am mounting it as a domain user with admin rights and full control over the share.ter mounting it as root, all the files are owned by root and I can't modify them from my non-root user.Here is how I am mounting the share:
mount -t cifs -o domain=example,username=example-user,password=mypassword //myfiler.example.com/myshare$/mydir /mnt/myshare/
This share is a qtree under a volume with security type set to NTFS. (Although I have also tried security type = Mixed) We don't configure user-level access to shares on the filer, we create directories and lay down permissions on those from the Windows side. (Although I have tried explicitly adding my domain user to the access list for the share)
I recently made the migration from mbox to maildir.I use postfix, spamassassin, dovecot for imap and procmail for delivery.I made the changes for Maildir to postfix main.cf, dovecot's dovecot.conf and procmail's procmailrc.All good, working well.Just noticed though, that mail marked as spam and filtered by procmail to be put in the users ~/Maildir/.spam/new folder are owned by root. Not allowing the users to even see it (600 perms)
So postfix sends all mail to Procmail:
mailbox_command = procmail -a "$EXTENSION"
But not all mail is effected, only mail picked up by this receipe in the /etc/procmailrc:

I am a linux newbie. I have a situation where I need to send a command line -X command to a screen session owned by root from a nonprivliged account. The command is executed by a shell script, which in turn is executed from a PHP script. Is there a way to make this work?
View 3 Replies View RelatedYes, I know this is not a good practice, and this is only a short-term solution.I have a server with a web-file-server daemon running internally as root, so the permissions for all files it transfers/creates have a uid/gid of 0:0.This is fine for the daemon, but I would like to manage those files from another workstation - actually a few workstations on a very limited LAN subnet - through NFS. How would it be possible to have users from a certain subnet mount NFS with root read/write abilities?I have seen the anonuid/anongid options (for the /etc/exports file), but I'm not so sure this is the right way to go.
View 5 Replies View RelatedWhen I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.
View 4 Replies View RelatedOn my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.
Can a sudo user do everything what a root user can do? I read sometimes expert say "You should run it as root rather than sudo user".
