Chgrp Not Changing A File?

I can't believe I wrote a looong message and it logged me out when I tried to submit it.

So anyway, in short lines:

- I have a network of sites where all sites share same "images" folder
- I have created /home/_images/entities and symlinked it from all websites
- It works great with Apache, when I open /images/ on any of the sites I get list of images and can view them

The problem is suPHP which changes process ID of the PHP script to the file owner ID, so when I load site1.com, all scripts are executed as user1 (and files/folders created with those scripts belong to user1:user1). When I load site2.com, all scripts are executed as user2 (and files/folders created with those scripts belong to user2:user2). All these users do NOT belong to the same group, and I wouldn't like to change that as it is cPanel/WHM server so I'm afraid I'll screw something up if I change (primary?) group of all users.

Therefore I need to set it up in such way that all newly created folders and files under /home/_images/entities (owned by root) have read/write permissions for everyone.

Here's the command I used:

Code:

setfacl -Rdm o::rwx /home/_images/entities

To check it:
Code:

root@server1 [~]# getfacl /home/_images/entities/
getfacl: Removing leading '/' from absolute path names
# file: home/_images/entities/
# owner: root
# group: root
user::rwx
group::rwx
other::rwx
default:user::rwx
default:group::rwx
default:other::rwx

This looks fine, however when I try upload an image via site1.com it looks like this:

Code:

root@server1 [/home/_images/entities]# ls -l
total 24
drwxrwxrwx+ 5 root    root    4096 Jan 14 06:25 ./
drwxrwxrwx  5 root    root    4096 Jan 12 13:08 ../
drwxrwxr-x+ 3 user1   user1   4096 Jan 14 06:25 1/

And in folder "1" is the image (and thumbs folder):

Code:

root@server1 [/home/_images/entities/1]# ls -l
total 236
drwxrwxr-x+ 3 user1   user1     4096 Jan 14 06:25 ./
drwxrwxrwx+ 5 root    root      4096 Jan 14 06:25 ../
-rw-rw-rw-  1 user1   user1   225569 Jan 14 06:25 689048f221ab7c556f4d482a9d92b2d6.jpg
drwxrwxr-x+ 2 user1   user1   4096 Jan 14 06:25 thumbs/

My questions:

1) Why newly created folders do not have "write" permissions for everyone else [not user and/or group]? If I upload first image from site1.com, then I can't upload other images from any other site, while all sites can display them.

2) What is the + at the end of permissions list? (drwxrwxr-x+)

3) Why newly created files have only "rw" permissions for user, group AND everyone else, and not execute permissions? I don't actually need execute flag set here, but from my command you can see I've set "o::rwx" so it should be there (or not?)

Actually the real problem is #1 - other users can't write to this folder so users can't upload images from other sites nor other sites can create (missing) thumbnails.

I tried adding two users in apache group and given 775 permission to Document root but user is not able to write into files in DocumentRoot

Tried adding user and DocumentRoot Folder in sudo file but not able to do it recursively

please help


Thanks for reply,
I have already given chmod 775 -R DocumentRoot - for recursively writting permission
You have told to add user in www-data group and chmod 775 -R to DocumentRoot
usermod -a -G www-data <user1>

How can users in www-data can able to write in DocumentRoot which has apache:apache owner and group
please clarify...

Done below steps to solve this:
1) I have created a new group webdata and added required users in this group
2) set sticky bit to document root with below command
setfacl -m g:webdata:rwx -R /path/to/documentroot/
this command will set rwx permission to DocumentRoot so that members in webdata can have full access but still DocumentRoot user and group will be apache

I am a bit confused and not sure what to look up to fix this issue. When I log in as user, I cannot edit my /var/www/html files.

I have the ownership of /var/www/html set to apache:apache (using centos 7). When I check groups for user it shows user and apache. That does mean I'm apart of the apache group right, and if the /var/www/html is owned by apache, I should be able to edit?

Directory /media/data/torrents/ has permissions 775, user yzt, group transmission

yzt and debian-transmission are members of the group transmission.

transmission-daemon is run by debian-transmission, and the new files it downloads have permissions 644, owner debian-transmission, group transmission. This is a problem, because I can't later move the files as my user, yzt, and need to be switching to root to change the permissions/ownership to be able to do so.

Using sticky bit I could copy it to anywhere else, but I'm interested on actually moving the file, not just copying it. I could run transmission-daemon as yzt and problem solved, but I rather have that internet facing service running by a limited user, just in case some vulnerability is found on Transmission.

So my question is, how can I set that every new file created under /media/data/torrents/ has permissions 775 like its parent directory?

Code:

alice@alice:~$ grep 1003 /etc/group
alice:x:1003:
alice@alice:~$ grep 1003 /etc/passwd
alice:x:1003:1003:Alice,,,:/home/alice:/bin/bash

So there's nobody in alice's group except alice (for whatever that's worth)

Code:

alice@alice:~$ ls -ld dollstuff
drwxrwxr-x 2 alice alice 4096 Jan 28 10:55 dollstuff

alice clearly owns and has full access to the directory "dollstuff" which resides in her home directory

Code:

alice@alice:~$ grep 1005 /etc/group
common:x:1005:alice,dilbert,wally

there's another group of which alice is a member, and alice wants to share her directory with the other members of the group

Code:

alice@alice:~$ chgrp common dollstuff
chgrp: changing group of ‘dollstuff’: Operation not permitted

Why not? dilbert and wally do this very same thing on their machines on a regular basis. All are running fully updated Ubuntu 14.04.

"chown ladybug:common dollstuff" is also disallowed, although "rm -r dollstuff" does work.

Some files have owner as number

Why is it that some files or directories have the owner as a number rather than a name?

My ls -la listing for /var/www/html/ | grep moodle gives

drwxr-xr-x 45 1005 1005 4096 Jan 12 13.53 moodle

Who or what is 1005?

There is no such owner in /etc/passwd

How can linux store meaningful permissions information for a user or group that does not seem to exist?

Thank you

I wanted to delete a couple of files, so I did. Then I noticed that they were "write-protected". What does that mean? Why was I able to delete the files considering I wasn't the owner and the files did not have group write permission?

I have a directory structure and files I wish to change permissions on, but I don't want to change permissions on every file/subfolder along the way. Example: I want to chown all files in dir4 where my directory struture is:
/dir1/dir2/dir3/dir4/*
However, both dir3 and dir4 are owned by root:root so I need to change the ownership on those directories as well. But, if I do:
chown -R user:group /dir1/dir2/dir3/dir4/
...it will indeed make dir4 and it's files accessible, but it doesn't change dir3 - so folks still can't get to the files they need. I thought about doing:
chown -R user:group /dir1/dir2/dir3*
... but that will give users access not only to dir4 and it's files, but any other files under dir3 which I don't want.

My work around has been to do a chown on /dir1/dir2/dir3 and then a second chown on /dir1/dir2/dir3/dir4/, but I am thinking there has to be a way to do what I want in a single chown command - right?

Hello, I'm sort of a novice Linux user and was running into an issue with user migration. I'm trying to migrate users and groups from a RHEL 5.11 install to a CentOS 6.6 install, both systems are 64 bit. Initially I tried to do an rsync of the passwd, shadow, group and gshadow files with no luck. When trying to login with an existing account on the new server I get access denied. I tried to change the password on the new server, but even then it doesn't seem to change the password and I still get access denied. I then tried to tar up the four above files and then extracted them on the new server, but the same issue existed. I also created a new account on the old server, copied all the necessary files over to the new server and still have the same issues. Any ideas what I may be doing wrong or what I can try next? This is getting frustrating!

Thanks!

Hi,
I just upgraded my server from Debian 7 to Debian 8. Everything seemed to go fine. However, Apache doesn't seem to be able to see the web files. If I go to my server's IP, I get an empty directory listing, as if the document root was pointed to an empty directory. However, my apache.conf points to /var/www, and there are indeed files the
Code:

root@maples-server:~# ls -la /var/www/

	# Possible values include: debug, info, notice, warn, error, crit,
	# alert, emerg.
	LogLevel warn

</VirtualHost>

Additionally, the connections are no longer showing up in /var/log/apache2/access.log. The last access time in that file is from before the update. I don't know enough about systemd to know if it is responsible for redirecting the logs to somewhere else...

At this point, I have no idea why it's not working. If anyone could point me in the right direction, I would really appreciate it.
Thanks!

EDIT: After looking around some more, it seems that the output of "apachectl -S" is helpful. So here it is:
Code:

root@maples-server:~# apachectl -S

It appears that it's looking in a subdirectory html, which was not the case previously (before the upgrade). I've currently got a (ugly but useable) work-around using a symlink:
Code:

root@maples-server:~# cd /var/www/
root@maples-server:/var/www# rm -r html/
root@maples-server:/var/www# ln -s /var/www/
root@maples-server:/var/www# mv www html
root@maples-server:/var/www# ls -l html
lrwxrwxrwx 1 root root 9 Apr 28 22:36 html -> /var/www/

While this does work, I'd like to find the proper way of doing it. Any ideas?
