General :: Security Group Can Be A Member Of Another Group?
Aug 22, 2010I 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?

General :: Group Member Not Able To Write To Group's File?
Feb 8, 2011I 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?

Software :: Member Of Group Root / But Root Group Permissions Don't Apply?
Apr 20, 2010A 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.

Jul 7, 2011I'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

Security :: Add A Group Of Users To The Wheel Group?
May 19, 2010I 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?

Oct 29, 2010I'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.

View 4 Replies View RelatedSecurity :: Default Group For Multiple Developers?
Feb 9, 2010OK I have multiple developers on a system and I have setup a area on the web server where they all should have access to and all that fun stuff. Now I do not want to setup these developers default group to be this single group cause they could be members of multiple groups...
IE:
/var/www/cust1 - Group Cust1
/var/www/cust2 - Group Cust2
etc...
Then say for the developers:
dev1 - member of Cust1 & Cust2 - Default group is dev1
dev2 - member of Cust2 - Default group is dev2
dev3 - member of Cust1 - Default group is dev3
So when they go into say /var/www/cust1 only dev1 & dev3 should have access to modify files and when they create/edit files the owner should be the user and the group I want it to be Cust1. Then when going to say the Cust2 area new files and stuff have Cust2 group access with RWX.
Is this possible for users to just use their normal accounts, or will I need to look are setting up "project" accounts where they can su into say dev1cust1 account which will have the default group of Cust1?
how you all handle this and what I might be able to do so that the permissions stick.

Aug 21, 2009I was about to post a new thread and saw that there are several answers out here already and I have done the new group permission one on my server -- actually on my test server I just added "my user" to the group "root" to gain rw access to /var/www/htdocs/.Someone suggested that the proper way might be to do symlinks to the directory in a real production environment and I wanted to find out if that is the *best* way to go or whether to actually make a group "www_admin" (pick your favorite flavor of this) and add my users to that group?
I guess I am looking for the "best practice" in a real corporate production environment that is most secure.

View 2 Replies View RelatedSecurity :: Group Write Access For Newly Created Files / Directories Without Changing Umask
Apr 3, 2009I have several directories, each owned by root and a group of the same name,By setting the sgid bit, I made sure that newly created files and directories are owned by the correct group, and that directories have the sgid bit set too.On each newly created directory or file, the permissions are set to 755. This is because this is the default umask, and I cannot change a users umask. I actually only want files created below a particular directory to have group write access, inheriting this behaviour to newly created directories properly.I'm not on samba or NFS, I have to do this for SSH users.The filesystem is ext3.I started to fool around with ACLs, but couldn't find what I was looking for.
View 3 Replies View RelatedFedora Security :: Limiting Sudo - Giving Full Privileges To The Wheel Group In The Sudoers File
Feb 15, 2011I have previously set up sudo via adding my name to the wheel group and then giving full privileges to the wheel group in the sudoers file. Now I choose to learn to limit that. Had noticed the most frequent use I have of sudo is to run yum update. This got me thinking, could I remove the wheel group privileges and add the following line in sudoers to limit the privilege to simply running yum, and furthermore, make it so I could run yum without a password:
## Allow root to run any commands anywhere
rootALL=(ALL) ALL
Troy ALL= NOPASSWD: /usr/bin/yum
I think that would in fact work (if I understood one of the pages here, it will work). However, upon further thinking I realized that in such a case then anyone sitting at my computer could then use yum, without a password, to install or remove any file on my system � probably not a good idea. As a result I have to ask, can I tighten the privilege even further such that the only privilege so given was to run �yum update� and nothing else? (for example if they ran �yum install� it would fail). If you can do it, how?
Last, I was going to limit the privilege, time wise and try wise, by adding the following to the sudoers file:
# Defaults specification
Defaults:Troy timestamp_timeout=0, passwd_tries=3
Will that really work to limit the elevated privilege so I don't have elevated privileges lingering about, or is there a better way to do so?
