We are aware that unix has three sets of permission such as owner, group and others. I have a requirement to have a read-only access to a folder and sub-folders and the group that currently holds can't be used. Because it has write privileges. I would rather not prefer to use others, because it opens to each user in the system.have read-only access for another group?
View 1 RepliesOn RedHat 5 64-bit.I have a group that requires read-only access to the /var directory.I believe someone mentioned SGID and ACL stuff, and I've been researching this solution, but I wanted to check with you all first to ensure there wasn't an easier way to do this. Basically, I just need folks that belong in this certain group to read the contains of any file/directory contained within /var.
View 5 Replies View RelatedWhat I want to be able to do, is have create a group, for example called "group1" and set its default permissions to read & write, instead of the usual just read.
So when I add a user into "group1" they automatically have read & write access to all files & directories which is in "group1".

I Want to be able to let my girlfriend view my pictures folder while at the same time keeping my sister out. So I created a group "JessAndI" and made myself and her apart of that group. I changed the group of the directory recursively to "JessAndI" and gave the permissions to 770. She still isn't able to access or even view the directory unless i change the permissions to allow others whether it be 774 or 777. Am i doing something wrong? I've checked and double checked to make sure she is part of the group and the group is the group on the directory and all the sub-directories and files.

I'm trying to give myself access to /dev/ttyS0. This is because I'm developing code that uses a serial port. While I'm developing this code I don't want to be continually working as super user. I have the following information about /dev/ttyS0:

So as root I added myself (username freddy) to the group uucp. This is just temporary, for while I work on this code and try different stuff as user freddy. Once the code is established and I have a single program with a fixed name, I plan to give myself an entry in /etc/sudoers that will allow me to run the finished program.
Here's the info on user freddy:

The problem then is that now if I try to use /dev/ttyS0 I can't.

I thought that if I was a member of group uucp which is associated with /dev/ttyS0 that I would be given rw access to /dev/ttyS0. What am I missing here?

I'm running RHEL 5. When using the GUI System>Administration>Users and Groups, I get the error: The user database cannot be read. This problem is most likely caused by a mismatch between /etc/passwd and /etc/shadow or /etc/group and /etc/gshadow. The program will exit now.
Some research showed that I need to use vipw and vigr respectively to find an inconsistency between these two sets, which I did - to make it easy I copied each from [vipw | vigr] to an excel file and did =exact(%1, %2). There are no inconsistencies.

Long time reader, first time poster. I've got, what has become to me, a brain bender. It seems ACL's are the best way to go, but I am not 100% sure.

I need to create a user with least permission on the production server. He should only be able to read or execute the files that to be specific. For example: I just need to give him a set of commands to run.Besides those command execution He should be prevented to run any other command and He should not able to create any files(write permission).
How would i proceed about this.
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

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 am trying to setup a Rsync backup method.I have multiple files and folders all OWNED by different users.Now I can read the files as root.But I want to make a user for RSYNC that can ONLY read all these files for copying them across.It requires to create a non password login and I dont want to do that with the root user ! I have tried to create a new user and use 'setfacl':setfacl -m u:someuser:r /var/test.But when I su to 'someuser' I cannot copy the files to my homedir. So I think it wont work for rsync also.

View 4 Replies View RelatedI'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.
We are using Nagios Server for different sites say India,US,Germany. All of them are in their respective groups. Now how do i create web access to 3 of them, so that they can monitor only their server? Say, India shouls be able to see and monitor only India group, US guys should able to monitor only US servers. And they not be anle to access other group.
