General :: Chmod: Changing Permissions Of Public_html: Operation Not Permitted

Apr 6, 2010

I run a small site and today I've discovered that my site is down. I found that cPanel has flagged the account suspended even though I haven't got any quotas on the account. I don't know what went wrong. I've tried to unsuspend the account in WHM but a certain part of the function failed.

Quote:

safe_userchgid: chown: /home/crocbits/public_html: Operation not permitted at /scripts/cPScript/SafetyBits.pm line 93.

After searching the internet someone mentioned that the problem might lie in the permissions of the public_html folder. I had a look at the permissions and the folder had no permissions d----- When I try to chmod the folder I get this error:

Quote:

chmod: changing permissions of `public_html': Operation not permitted

I have no idea what to do next. All the files in the directory are locked too. I tried to move them but this command isn't allowed either. I ran these commands under the 'root' user in SSH.

General :: Chmod Doesn't Change Permissions On Files In Subdirs

May 15, 2011

I have a Qnap 219p NAS to which I have connected a USB external harddrive. I can access the external harddrive from my windows box using the network share, but at first i couldn't access the folders. The permissions set in the NAS GUI for the external drive is correct and are identical to the permissions set to the 2 internal drives.

I ssh'ed to the nas and used 'chmod -R 770 /share/external/sds1' - this granted me access to the folders, and some files. I can open all files in the root, but if I go just 2 folders 'deeper', i can't open the files in this folder, and in the folders after that.

In ssh, if i navigate to the folder wher I cannot open the files and use 'ls -l', i can see that the permissions (770) hasn't been applied to these files. How can I get chmod to apply the 770 permission to all files, folders, subfolders and files in subfolders etc., without having to chmod every folder one by one?

General :: File-permissions On Read-only Media: Allowing For Access Without Chmod?

Mar 14, 2010

I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.

I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.

Ubuntu :: Avoid Users Writing On The Same File?

Feb 27, 2011

Is it possible to forbid that more then one user open the same file in rw mode? In windows when you open a file that another user is using, there's ad advise and you have to open it in read only mode

I installed ubuntu 10.04 desktop edition on 3 pc (there is not a server-client architecture). I installed samba.(and smbfs)

put the strings:
[name]
comment = ...
path = /...
guest ok = yes
read only = no
create mask = 0777
directory mask =0777

Computers that access to that directory do (on boot, with root privileges)
mount -t smbfs -o username="user",password="pass" //192.168.0.12/name /mnt/cartelladimontaggio

But if two users access to the same file, both are authorized writing on it! So changes made by one are lost when the other save.

General :: Writing A Script That Changes To The Home Directory?

Oct 5, 2009

but I won't get any better at this unless I dive in, so here is the question in full that I am having trouble with and I'm sure you can all get a good laugh at:Write a shell script called nbin. First the script changes to the home directory. Then if there is a bin directory under the current directory, display the message bin has XX files". (Note: the XX will be substituted with the actual number of files in your bin directory)

So far I have done:
vi nbin
#!/bin/bash
PATH=/bin:$HOME/bin

Jan 26, 2011

I want to have two kind of users in a work machine having ubuntu 10.04,

1) He is the admin, have sudo privilages and install, do all types of work, his username is abhilash

2) A user who is normally a IT administrator, who can just install or remove softwares, but cannot access files of abhilash.

I'm trying to do this and my head is going blank, The problem where i'm stuck is, if IT admin can install softwares, then he can become sudo as sudo su, then he can view my files

So here is a small test i did, first with abhilash.

Code:

Now others and group don't have any permissions! But when IT Administrator becomes root, he can see this file

Security :: Folder Permissions To Avoid File Upload By Http User?

Feb 24, 2011

However, 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.

Debian :: Suid And Writing Files Permissions In The ET Server?

Feb 22, 2010

I have tried to configure an Enemy Territory Server in an way that a common user could run it just executing a command line. The first thing I did was writing a script like that

/usr/local/games/enemy-territory/etded +set dedicated 1 +set net_port 27960 +set fs_game etpub +set fs_homepath /usr/local/games/enemy-territory/27960 +set sv_punkbuster 1 +set +exec server.cfg +set +exec punkbuster.cfg  +set +exec bots.cfg

and then putting it in the /usr/local/bin directory. Ok, the things seem to be fine, but then I realized that the program tries to write some config and log files. I noticed that because some warnings appear in the command line, like that Couldn't write etconfig.cfg always that I run the command as a normal user. On the other hand, if I give writing permission to these files, all the warnings disapear.
But I don't think it is a good way, because someone could change these files by hand, what would not be good.

My last try was to set the suid of the script up, with the command chmod u+s /usr/local/bin/etded-server
But as I already knew that suid does not work well with shell script I wrote a C source like that:

Software :: "chmod O-rwx" Removed All Permissions?

Jun 15, 2011

How did this happen?
This is on SLES 11:

Code:

totalt 32
drwxr-xr-x 7 ctuser ctusers 4096 8 jun 13.33 admin
drwxr-xr-x 5 ctuser ctusers 4096 8 jun 13.45 ct
drwxr-x--- 6 ctuser ctusers 4096 8 jun 13.50 extadmin
drwx------ 2 ctuser ctusers 16384 15 apr 13.20 lost+found
code....

How on earth could all permissions be removed on SLES??And it is NOT a typo, I did type in "o" not "a" - checked and doublechecked. Also here the code is pasted from cli not rewritten.(All is done as root, both in SLES & Debian.)

Ubuntu :: Made An Error With Chmod - Create User But Don't Allow To See The Other User's Home Folder

Jan 18, 2010

I wanted to create an user but don't allow it to see the other user's home folder so I made chmod 0750 /home/folder and it worked fine so I went ahead and decided to completely forbid access to the root folder and I had the "great" idea to make chmod 0750 /, and now I'm having problems with wine and other applications, in example I used to have a folder in this address 209.239.114.51/mmgr but now it's giving me errors and if I try to run some applications I got error "There was an error creating the child process for this terminal"

Ubuntu :: 11.04 Update Error Message About File Permissions And To Check Connection?

May 3, 2011

I had to register with a new username, because I could not remember my logon details and have since changed ISP so could not get details sent, anyway that aside to the problem.

I upgraded to 11.04 and all went well (hence posting here and not in the Upgrade section) and it is running fine, well until yesterday.

I ran the update manager as I usually do when first entering Ubuntu and it did an update but then gave me an error message about file permissions and to check my connection (which was connected OK).It has also affected the Software Installer, and now I can not install any new software.

Is this a generic problem with the latest update or is it just my Dell Inspiron 1545 please?

Ubuntu :: Recursively Changed Permissions In Home Directory

May 23, 2010

I did a clean install from Ubuntu 09.04 to 10.04 and restored my files from tar.
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:

Code:
~/Documents$ ls -A
ls: cannot open directory .: Permission denied
~/Documents$ sudo ls -lA
[sudo] password for wolf:
total 80
drw-r--r-- 2 wolf wolf 4096 2010-05-22 20:45 career
drw-r--r-- 23 wolf wolf 4096 2010-05-02 17:17 computer_languages
drw-r--r-- 2 wolf wolf 4096 2009-08-09 23:29 .ecryptfs
drw-r--r-- 21 wolf wolf 4096 2010-05-02 17:23 misc
-rw-r--r-- 1 wolf wolf 27298 2010-05-23 13:01 next.odt

drw-r--r-- 5 wolf wolf 4096 2010-05-08 01:43 software_projects
Now I can't even look at my own directory:

Code:
/home$ cd /home/
/home$ ls -lA
total 20
drwx------ 2 root root 16384 2010-05-07 01:01 lost+found
drw-r--r-- 42 wolf wolf 4096 2010-05-23 15:35 wolf
/home$ cd /home/wolf
bash: cd: /home/wolf: Permission denied
/home$ sudo cd /home/wolf
[sudo] password for wolf:
sudo: cd: command not found
