Software :: Member Of Group Root / But Root Group Permissions Don't Apply?
Apr 20, 2010
A bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.
I have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP ... GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW
[code]....
Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?
I need to create a group that has the same permissions as the users group. Can I have the new group be a member of the "users" group to inherit its permissions?
i want secondary users can able to change the files permissions of primary group?user MAC is having www as a primary and httpd as secondary group. But he want to change the file permissions (chmod) httpd group files. Is it possible or not? I think its not possible. If it`s possible then let me know how?
I'm seeing on my Fedora 15 box. I want to add the superuser to a group called, say, thisgroup.thisgroup is absent. Surprisingly, when I thought of editing /etc/group, root was present there!Anyone on why groups didn't show my new addition?
I recently installed Ubuntu 9.10 and have been trying to set up a USB printer. I hit a problem which I eventually diagnosed as being the ownership of /dev/usb/lp0.
First, the symptom: ~$ cat Test > /dev/usb/lp0 bash: /dev/usb/lp0: Permission denied
The initial diagnosis: ~$ ls -l /dev/usb/lp0 crw-rw---- 1 root lp 180, 0 2010-03-23 21:39 /dev/usb/lp0
Notice the lp group? When I checked group properties, this group did not have any members - not even root! The default for CUPS (from the CUPS doc) is lpadmin, in any case, so not sure what lp is all about. In fact, the 'lp' group has ID=0, the same as the 'root' group.
I fixed it by doing this: ~$ sudo chown root:lpadmin /dev/usb/lp0
Then I noticed that /dev/lp0 and /dev/parport0 also had group=lp, so I also did this: ~$ sudo chown root:lpadmin /dev/lp* ~$ sudo chown root:lpadmin /dev/parport*
I have a question about LVM. My /dev/sda disk is partitioned into Windows NTFS on sda1, Linux /boot partition on sda2, and the Fedora 10 root (/) LVM partition is on sda3. I have moved my Windows XP to VMware on the Linux system and would like to add the sda1 partition to root LVM group.
I am using redhat 3.0 i want to configure arp-acl mac based blocking to windows clints i have done bellow configuration but finally squd starting error is showing

I am trying to extend my / size as its full. Well the volume group is VolGroup00 & logical volume is LogVol00 but when. I run the command vgextend VolGroup00 /dev/sda8. It says volume group not found. Can it be because I have WindowsXP in my /dev/sda1, which falls under same Volgroup??
I'm having an odd problem (although I'm probably missing something obvious to a non-semi-newbie):I have a directory used for samba shares which is owned by user fred, a system user which the windows clients on my network authenticate with to access the shares. I, roger, want to access the directories without having to put my 'sudo boots' on every time, so I made the directory group users and added roger to that group, and changed the file/folder modes from 0755 to 0775.However I still do not have write permissions inside the directory; I still seem to be considered 'other' and hence only have read and execute.
According to a couple of different places, it's not possible for me to put a line in /etc/fstab to mount one of my partitions with owner and group not root; instead, I have to mount it in /etc/fstab, then chown & chgrp to my user. That seems ridiculously tedious and silly... is it true? I'm sure a short script could be written to get around it, but it seems obtuse for Linux not to allow that to be set in /etc/fstab.
After freshly installing Lucid Lynx and tinkering for some time to get everything just how I like it, I managed to somehow remove myself and all other users from all groups. Now, obviously, I've restarted and I don't have root privileges as I am no longer a member of admin group. So I am somewhat stuck. I've looked at this page: [URL]. But annoyingly, there is no grub menu appearing on boot up (unlike previous Ubuntu versions). So I'm appealing for your help to either:
a) Show me how I can bring up the grub menu so I can access ubuntu in safe mode
b) Show me another way of accessing the system with root privileges. (Would using chroot from the Live CD work? I just thought of that now so I'll try it).
The normal user is now in the sudoers group. How can i allow it to install programs using it's own password rather than having to know the super-secret Root-Users password?
I'm running Ubuntu 11.04 (guest) on Windows 7 (host) with the guest additions installed. I have an auto-mount folder that maps to my D: drive on the host which I can access using sudo ls /media/sf_D_DRIVE - however, even when my user (ross) is a member of the vboxsf group I get a permission denied error when attempting to explore it. I have restarted since adding my user to the vboxsf group.
This should work because I am a member of the group (which has rwx rights), so why doesn't it?
ross@panther:~$ ls -l /media total 8 drwxrwx--- 1 root vboxsf 8192 2011-07-03 22:24 sf_D_DRIVE ross@panther:~$ ls -l /media/sf_D_DRIVE/ ls: cannot open directory /media/sf_D_DRIVE/: Permission denied
How can I create a user group that restricts Internet privileges to only members in the group, then I will assigns certain applications to join the group for access to the Internet.
For example, I want only group net to have access to the Internet. Group net is then connected to:
Code:
So far, I am using the gnome group policy manager that is standard with ubuntu but Its not working. It is possible that im misdirected and that I should use a firewall instead?
I have a text file that currently has around 150 000 usernames in it. I need to somehow group them into smaller groups of 1000 and then add that value into the DB. for example user xzy group 1 (hopefully the groups will be digits incrementing)
[Code]....
how to search for 1000 then assign them group 1 and then 1001-1999 to group 2 etc.
I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)! EXT3-fs: group descriptors corrupted! mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.
Mount of filesystem failed. A maintenance shell will now be started CONTROL-D will terminate this shell and retry. groups: cannot find name for group ID 0 root@Sergioc-desktop:"#
I have a number of users, categorised into various groups. I would like one of those groups ("developers") to be in the wheel group as well. I don't want to just copy the people from the developers group into wheel, because then when that group changes I'll have to change it in two places. Is there a way to specify that anyone in developers is in wheel, and have that be dynamic?
i am trying to finish up a lab in that i have i have some accounts created under groups called "mgmt" and "pl". I am trying to figure out how i can get the guys in "mgmt" to be able to modify files in a directory called "mgmt-final" but the guys in the group "pl" will only be allowed to read those files.

You wouldn't think that would work with getting video but no sound, but it did in my case. I'm having all the same problems, but I'm using DSL-N, and I can't figure out how to check or change the group permissions.
I need to assign permissions for ftp users. For that I need to create groups with different permissions like upload, download, rename, delete, rename and delete. And the users added to the group need to have that group permissions by default.
I am doing rhce course but i am very confused to answer these user and group permissions.the questions are like this...the owner of the /data must be user tom.primary group of /data must be the group sysadmins.the members of the group test must be able to write and create files in the /data.the members of the group web have no access to these directory.the user jack not belong to any of these gropus must have to edit files created in /data.the user tim can only list the contents.
the questions are always like these..i am okay with sgid and sticky bit.but i dnt know where to set default acl and other permissions.
I am running into a Brick wall with this. And thought that the knowledge and expertise here would be a good place to seek help.I have CentOS 5.4 server running Samba on a WinBloZ network. I have the groups all setup and that aspect works fine. But here lies the issues.In a shared directory with group permissions set if someone on the group with permission to this directory creates a file they are the only person that can edit / modify that file. That file need to be editable by the entire group. But the only way thus far I can achieve this is to manually chmod the files in the directory. I know there is a way to fix this, but I have not found it. Can someone please explain how to make this work for me.
This is a interesting confusing problem.Ok I have group with 3 users.I have a folder in /home with owner as root, and group that has read/write permissions.However if a user opens up a file and saves it via samba, the owner changes to the user, and the group members only have read permissions on the file.
Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?
A colleague of mine has a Linux box (running Debian I believe) with an SVN repository on it. The repository directory and files 'owner' is my colleauge. We are both members of a group called 'users'. He manages several projects both Linux and Windows apps, while I have one Windows app. For the Windows apps, we both use TortoiseSVN via an SSH link to commit/update. Performing the command 'ls -l' shows the repository files and folders on the Linux box to have the following permissions:
-rwxrwx--- john users
However, when my colleauge commits to the repository, the permissions change to:
-rwxrwx--- john john
This then means I get 'Permission denied' when trying to access the repository myself as it appears that the group permissions have been overwritten with only 'owner' permissions. To fix this, a 'chown -R' command is applied to the files/folders to set the permissions back to owner/group, but each time he writes to the repository, the issue repeats.
