I downloaded GNU coreutils and compiled them both identically on two different computers running Ubuntu 10.04.1 LTS. I performed a random audit, MD5 checking on chown, and they both have different checksums. Does anyone know why this has occurred?
View 6 RepliesI issue the command 'dd if=/dev/hdc|head -c 4294607004|m5sum'. But the checksum I get is not the correct one. Its not the checksum of the first 4294607004 bytes in /dev/hdc. And the message dd outputs is
8387904 records in
8387904 records out
Then I find 8387904 * 512 (512 because 4294607004 / 8387904 = 512.0000186) = 4294606848, which falls short of 4294607004 by a few bytes. But 8387905 * 512 > 4294607004. So I issue 'dd if=/dev/hdc ibs=512 count=8387905|head -c 4294607004|md5sum'. the message is still the same:
8387904 records in
8387904 records out
I checked a couple of locations:[URL]... and none of the files listing checksums do so for the LiveCD ISO neither md5 nor sha1. Being a "trust but verify" sort of fellow. . .
View 3 Replies View RelatedI usually install or upgrade using Ctrl + alt + F1 console in init3 mode.Despite this and while using # zypper re && zypper up i notice that often times upgrade is stopped when checksums are changed. Last day 250 packages could not be upgraded because of maybe 5 packages with changed checksums. Sometimes clearing zypper cache with zypper cc does the trick but not all the time it works, I had to force install manually to be able to upgrade. Is it possible that upgrade is not impeded by such changes ? If not is it at least possible to have a list of changed checksum packages to be able to remove them or install them manually more easily ?
View 1 Replies View RelatedSometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

View 0 Replies View RelatedFor the second time in a week, I have set up an unmanaged CentOS 5.5 Storm Server at StormOnDemand, only to discover a ton of unauthorized changes to binaries (updated file checksums and sizes) on the server shortly thereafter.The time stamps do NOT change.If the time stamps did change, I would be hunting down ahat was doing some auto-updates. But the time stamps are not changing.This leads me to believe that either these servers are suffering from:1. A virus or hacker is compromising the box.2. system corruption.3. Something else? To eliminate the possibility of number 1, I toasted the first server and started over with a new server and enabled their firewall from the start to only allow access for two IPs via SSH... my IP and my biz partner's.
Then, one of the first things we installed was a system we created that maintains a snapshot of most directories on the system so that it can be used to watch the live directories for changes. At 4:07am (server time) this morning, we received notice from this system that a massive number of files had changed in these directories. Again, no file time stamps changed.So, my question is this... is there any legitimate reason in a fairly standard CentOS 5.5 install that would cause so many files to change?

View 2 Replies View Relatedtitle says it all. I know, I know, a recursive chown, what was I thinking. It was late.
I just straight up:

I am currently responsible for administering a shared Ubuntu machine with several unrelated users. Some of these users own multiple accounts and would like to "chown" files between them. Currently, I must handle such requests manually, and this is inconvenient.
I am looking for a way to allow non-root users to chown files with authentication (i.e. prompt for the password of the user to which ownership is being set to). This would prevent an exploit such as:
Quote:
cp /bin/bash ~/sudobash
chmod 4777 ~/sudobash
chown root:root ~/sudobash
Does such a solution exist?
I am trying to modify the user and group for a directory on my SD card, but I get an "Operation not permitted" error even when I'm signed in as root. I have the SD card auto mounted using:

I did the chown task, as root, and the file icon still has the lock symbol on it. I did it on another file on my desktop just before that, and the symbol went away.I checked 'Properties', and it shows me as owner.It's an ISO on my desktop, copied from LXF Magazine DVD.

I've got a bit of an issue here. I'm running OpenSUSE 11.1 with an old Windows XP drive slaved on the secondary cable. Works just find, as long as I sudo mount it (sudo mount /dev/sdb1 /windows/C) and I can access everything I have on the drive; this is not the issue. The issue is that I have another drive that I want to sync up. Eh, this needs to be a bit clearer.
When I have /windows/C mounted, it shows a padlock on the C drive, but not windows folder. (/windows/C). I have a dedicated entry in / to allow windows to work. I have maybe 25 folders in my Music folder that I want to sync to my /C drive, as I plan to re-install Suse on a bigger drive, and don't want to lose this music.
Upon su *password* into root, I can ls -l and I get

The reason I want to get this stuff transfered over is because I'm running out of room on my smaller drive and I figure I may as well utilize a 200GB HDD for something besides a paperweight.

My home/container has me as the owner but the contents all belong to root...I've tried >chown cbjhawks /home/cbjhawks but that didn't change anything. Should it be >chown -R cbjhawks /home/cbjhawks? Or what is the proper command for doing this...
View 2 Replies View RelatedI have an external drive which is parted into two partitions:

Since I re-installed jaunty the NTFS partition is owned by root. Whatever I do to make it change, it doesn't work. I used:
sudo chown jan:jan NTFS

View 1 Replies View RelatedI would like to change the ownership of some all folders and files within them folders by making changes to parentfolder. But I mess it up.
The folder path is /home/myaccount/shared/target_folder.
Target folder holds several new folders with files inside. How can I easily change ownership to all folders and files within target_folder?
I tried this:

Unnable to resolve. No such file or directory.
When I installed a new copy of my distro on another partition, in order to preserve all the settings from my old my user account, I made a user account with the same name on the new installation, and then copied my old user account's files (in their entirety) to the new user account, overwriting it. I did the copying from the root account (where else? I assume the new user account can't overwrite itself while it's open), and root became the owner of everything I copied, making it impossible to open the new user account. So I then chowned the new user account's folder to myself. I still can't get in, because apparently, chown only chowned the top folder, leaving all subdirectories owned by root. How do I make chown include all subdirectories? I scanned the man page, but didn't see a parameter.

2) Use the umask command to change your file creation mask such that,by default for new files and directories you create, no permissions are taken away from the 'user' (owner), write permissions are taken away from the 'group' (group owner), and all permissions (read, write and execute) are taken away from 'other'. Take a screenshot of your terminal window showing the results of this step.
3) Use the touch command to create a new file called testfile. Use the ls command to display the contents of your current directory in long mode. Take a screenshot of your terminal window showing the results of this step. Ensure that the directory listing for testfile is completely visible in your screenshot.
4) Use the chown command to change the user associated with testfile (the owner) to cint201. Take a screenshot of your terminal window showing the results of this step.
5) Use the chgrp command to change the the group associated with testfile (the group owner) to users. Take a screenshot of your terminal window showing the results of this step.
6) Use the chmod command to change the permissions for testfile such that the 'user' (owner) permissions are set to read, write and execute, the 'group' (group owner) permission are set to read and execute, the 'other' permissions are set to grant neither read, write nor execute, and finally set the SUID bit for the file. Take a screenshot of your terminal window showing the results of this step.
7) Use the ls command to display the contents of your current directory in long mode. Take a screenshot of your terminal window showing the results of this step. Ensure that the directory listing for testfile is completely visible in your screenshot.
