I changed the permissions of /etc/sudoers trying to make it writable using following command:
sudo chmod o+w /etc/sudoers
and now when i try to use the sudo command i am getting the following error:
/etc/sudoers is mode 0442 should be mode 0440
One of our client was complaining that their server was down and mysql and apache services were down. The server is Ubuntu 8.04. When we checked, the permissions of /etc/init.d/mysql and /etc/init.d/apache2 were changed to 644 from 755. How could this be possible?I need your valuable suggestions on how can i monitor whether any malicious intrusions or scripts are running.

I recently got a T-Mobile Tap and I've been trying to connect it via USB to my laptop running Lucid.When I open up the icon that shows up on my desktop after connecting it, I can't run the setup files inside. It says: The file '/media/HUAWEI/checksetup.exe' is not marked as executable. If this was downloaded or copied form an untrusted source, it may be dangerous to run. For more details, read about the executable bit.When I try to change the permissions from ready only, I get: Sorry, could not change the permissions of"checksetup.exe": Error setting permissions: Read-only file systemCan I tried calling T-Mobile but they said they don't troubleshoot with Linux. They said it's an "older operating system".
View 2 Replies View RelatedI have an NFS server on Windose Server 2003. I use it to back my Linux/Solaris databases up to. I mounted the NFS share on the Linux box. I was testing the permissions to it, and accidentally did a chown sybase:sybase /OLBackupOLBackup is the root directory of the NFS share. When I did the chown command, it changed the permissions on the share. Now it seems that linux is controlling the permissions. In windose I cant add users/groups. How can I remove Linux from owning the permissions. Im not sure if this is a windose issue or a linux issue, but figured I would start asking here first.

View 14 Replies View RelatedI've made a really critical and simple mistake and now I am trying to recover my computer. I accidentally logged into root and was trying to change permissions for the current directory with "." but instead used a "/" which started changing permissions of everything from / recursively. I quickly realized the mistake I made after it started and aborted the process by pressing ctrl+C. However I know many things are still not right because, even though I tried to reboot and change the permissions back to 0755 from the recovery mode root console. I still get errors when gnome tries to start..Here is the exact error I am getting. "There is a problem with the configuration server (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256". I'm pretty sure because of the way I aborted or because of the time the filesystem was running with 644 permissions, some amount of damage was done. Any way to recover it to normal? Or is there a way to recover it from the Ubuntu CD?
View 3 Replies View RelatedI have a recently setup my first linux server (hardy) and am having problems with the permissions for a log file being changed. I believe this is caused by syslogd, but am not sure how to correct it. Bacula will report it is unable to start a backup because it is unable to open the log file (/var/lib/bacula/log) "permission denied". After changing the owner from syslog to bacula, the backup will resume. However, the following day I encounter the same problem because the owner of the log has been changed back to syslog.I see where the permissions for logs are altered in sysklogd, but I am not certain how to make bacula exempt or if this is the right approach.

I wrote a C++ program that uses serial port in fedora. Since normal user has no permission to read/write to /dev/ttySx, the program doesn't work. if I changed the permissions using chmod in su, it will works for that session. When restarts the permission changed to default again. So what to do a normal user program to access /dev/ttyS0?

Everything worked fine until I tried my weekly rsync backup.
The permissions seemed to be causing problems, so I recursively changed all the permissions in my home directory:
Code:
~/Documents$ sudo chmod -R 644 /home/wolf/
[sudo] password for wolf:
chmod: cannot access '/home/wolf/.gvfs': Permission denied
So now all the directories and files have read permission for everyone:

I recently upgraded from Lucid to Maverick, and I noticed that a new error message caused by a "cp" command call, including the hard links option. Fortunately, I kept the last Lucid kernel (2.6.32-25), so I could check the different behavior with booting successively on each kernel. Here are my configuration files:
On the server (192.168.1.2):
/etc/fstab :
UUID=... /mnt/Backup ext4 defaults,errors=remount-ro,relatime,async 0 2
/etc/exports :
[code]....
If I check permissions of /net/Backup/Folder2 from the client, I get :
owner = nobody (Create and Delete files), users (Access files), others (Access files)
cp -alR /net/Backup/Folder1/* /net/Backup/Folder2
- under kernel 2.6.32-25: no problem
- under kernel 2.6.35-22: all the subdirectories are created, but all empty; moreover, I get as many messages as number of files from the source:
"cp: cannot create the link ...: operation not allowed"
I can copy manually any file to /net/Backup/Folder2 from the client. Why the behavior has changed from kernel 2.6.32-25 to kernel 2.6.35-22 ? Should I modify the permissions or the way the mount is exported with options like "(no_)root_squash", "all_squash", or "anonuid", "anongid" ?
I'm using rhythmbox and a classic ipod. A couple of times I have managed to write podcasts to my ipod. I'm not sure how I did it but it doesn't last. I have tried lots of random things from forum posts. When I try to change permissions in nautilus they change back straight away. I have my name as owner and group. I have the Lynx Ubuntu OP.

It even effects the waste basket-all the stuff in there is now read only and when I delete items I get a file operations window, which comes and then goes like its deleted them, but they re still in the waste basket, doesnt show an error message like it does if I try and move any other file.

View 2 Replies View RelatedAfter adding what I thought were the correct entries in /etc/sudoers so I'd be able to run commands without needing to sudo them, I keep having to. My sudoers file entries look like this:
Code:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
user_me ALL=(ALL) ALL
## Allows people in group wheel to run all commands
%wheel ALL=(ALL) ALL
user_me ALL=(ALL) ALL
## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL
user_me ALL=(ALL) NOPASSWD: ALL
I have also confirmed that I'm a member of the wheel group in /etc/group:
Code:
wheel:x:10:root,user_me
And yet, I still have to sudo to do pretty much anything.
I added the following line in /etc/sudoers file
<username> ALL=(ALL) NOPASSWD:ALL
after adding this if I run any command it is not asking for the password. Now I need to shutdown the remote machine with sudoers user.
ok how do I include my username in the sudoers list?

I need to install a package. For that I need root access. However the system says that I am not in sudoers file. When trying to edit one, it complains alike!

Edit: I have tried visudo already. It requires me to be in sudoers in the first place.

We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

Relatively new to Linux, but I'm trying to grasp the proper way to modify the sudoers file. As an example, what would I have to modify in /etc/sudoers to allow a user (say 'user1' for the example) to be able to add/remove software through yum? I'm aware of the fact that I need to use visudo and how to use the vi editor. I've Googled this topic and while I've found a number of pages on the topic, I never see many examples.
View 5 Replies View RelatedThis is the hard way to learn when you MUST use visudo. That's right. I did something stupid like:Quote:$ sudo vi /etc/sudoersand now have:Quote:
$ sudo
>>> /etc/sudoers: syntax error near line 79 <<<
sudo: parse error in /etc/sudoers near line 79
[code]....
Warning: Do not edit /etc/sudoers directly with an editor; Errors in syntax can cause annoyances (like rendering the root account unusable). You must use the visudo command to edit /etc/sudoers. In the previous section we added your user to the "wheel" group. To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line:
%wheelALL=(ALL) ALL
so i signed in as root and typed in visudo now i alreayd made the changes but how do i exit and save super+x doesnt seem to do it for me since im not using nano and not supposed to cause it causes errors
