Security :: Setting File Permissions For File /var/log/Xorg.0.log?
Jul 7, 2009i am trying to set the file permissions for the log files "/var/log/Xorg.0.log" and "/var/log/gdm/:0.log". These files seem to be created when a user logs into a whokstation (my guess so far). I am trying to comply with a security mandate that all log files in the directory /var/log are set to 0640. The two mentioned files always seem to have the permissions 0644, does anyone know where and when these filea are created and how I might set the permissions when the files are created

Mar 3, 2010I am setting up a new ubuntu server, and I am quite new to linux. This server will be used as code repository for a project I am going to be working on. I plan to setup 3 groups for users: dev, test, doc
- for various developers, testers and documentation users.
I would like to setup the following permissions on the main code repository directory:
dev - write permission
test - execute permission
doc - read permission
public (anyone outside these groups) - deny all access
I am unsure what chmod setting to use, or if this is even possible in ubuntu.

Jul 6, 2011I know how to assign file permissions and other tasks like user to group, but I'm stuck with a situation in how I should set up my system.So I have a LAMP server set up. I'm not the only developer so I created a group called "developers" for my other users "Mike," "Alex," and "Cindy," which are developers (I'm Mike by the way). I know that "www-data" is the user and group Apache uses.This is good because only I have permission to update the production site, but for the dev site, it's a different story.

Jul 23, 2009Picture the following:On computer A, local user John (and John alone) has rwx access to file1.txtComputer B also has a local user account named John. If file1.txt was to be copied from computer A to computer B, would the user account John on computer B be able to access it?I guess this wouldn't work using two windows computers due to the User name / GUID relationship. Maybe linux has something similar?

View 9 Replies View RelatedSecurity :: Flow Chart For File Access And Permissions Processing?
Jan 25, 2011Is anyone aware of a detailed "flow chart" -- arrows and decision diamonds, etc -- that describes the file access and permissions processing? I would love to see that diagram. Years ago on a platform far away (Digitial VAX/VMS) their manuals had such a flow chart that covered not only the user-group-owner and read-write-execute permissions decision making but also include "access control list" processing at a superficial level. If someone has access to the VAX/VMS flow chart, that might be a start toward sorting what linux does.
View 4 Replies View RelatedSecurity :: Folder Permissions To Avoid File Upload By Http User?
Feb 24, 2011However, configured a website on a dedicated server using WHM/cPanel. The site was uploaded using the master account for the website.
The security issue is public users are able to upload files on to my server via the website. They could even access the root and execute whatever they want on the server.
I have consulted with 2-3 Linux experts. According to them, the PHP user has rights to execute anything on the server or upload & store files in whichever folder they want.
Can I protect my folders to avoid file uploads via the website. The application has security vulnerabilites. However, I want to prevent hackers to enter my site until the vulnerabilities are fixed.
Security :: Setup File Permissions For Multiple Groups/users That Use Windows?
Nov 2, 2010I have a remote directory shared over NFS called tech with perms set as 0750 and owner set to root:tech. I have 2 groups: tech, and techAdmin. tech can read and execute within tech/. techAdmin can read, write, execute.

If user1 creates a file inside tech, user2 cant read or modify it because user1 owns it. Here's a few sites that reference this problem:

Security :: Debian Shows File Permissions Change When Copied To A Windows Partition?
Dec 10, 2010Some time back using this computer a SucKit rootkit was found. Having dd urandomed the drive, flattened CMOS battery, flashed BIOS, run Knoppix live CD 6.1,using no flat pack battery (laptop), and memtested the RAM, I am still having problems with what I suspect is a javascript file that tries to reload the rootkit from? firmware. I suspect the firmware as everything else should have eradicated it??
Also it or a hacker via a backdoor then corrupts the drivers so devices malfunction. Windows security programs and rootkit detectors don't seem to pick it up. Fresh install of Windows or linux after the above still show this problem, though internet not used. The person who admitted rootkitting this machine is capable of writing java programs or using javascripts to do all this.
When viewed using Ubuntu 8.4 files and dates on a Windows partition appear normal both in file manager and terminal. However booting using Knoppix CD these files are all green, and I cannot change their permissions, even as root. ie: everything is green including text files etc. If I copy them to a linux partition, I can change their permissions and make them nonexecutable and nonwritable. Also on the Windows FAT32 partition the . directory has the date 1 Jan 1970.
If I disable any green files, I can shutdown and reboot cleanly. If I don't I start having problems shutting down [/usr/sbin/init ?] And always these follow a pattern:
Can't remember details as I have now corralled the beast but error messages relating to:
nfs-server
inet.d/statd
are the start of these.

View 8 Replies View RelatedSoftware :: Append Text To File
Dec 2, 2009I want to append some text to the file, files are mostly big, more then 100 mb. I found the cat command, so I can create a new txt file and then append it to the original file with it. Two questions:
1. Can I append text to the file instead of creating the new file and then appending it to the original file? eg:
Code:
cat file.avi "some text" > newfile.avi
2. cat takes several seconds to execute the merging files together, it seems that it is reading the original file first, is there a way skip the reading and just append the file?

OpenSUSE :: Append Text To An Entry In An Existing File?
Aug 30, 2010How do you append text to an entry in an existing file? For example, lets say I have a file called "env.logon" in /home/myself/bin that contains the following text:
PATH=/bin:/sbin If I wanted to add, via command line, ":/usr/bin:/usr/sbin" to the PATH= and I
used the "echo" command (echo "PATH=:/usr/bin:/usr/sbin) it would create a second entry and my file would look like:
PATH=/bin:/sbin
PATH=:/usr/bin:/usr/sbin
What I want is for it to look like:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Is there a way to get this result via command line?
