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.
ls -al /guests
I want to be able to assign the group "readers" read access to guests/c1 but it says access denied. but it shows r-x acsess. i want to be able to control who has read access and not just give it to everybody.
I would like to create a script for consistent user account creation and maintenance.
Current situation:
Server A
user1:11111:15:USER USER:...
user2:22222:15:USER USER:...
Server B
user1:33333:15:USER USER:..
[Code]...
Now i would like to make uid consistent on all servers for each user. Next time if user1 needs to be created on Server D it should automatically pick the particular uid.

I'm setting up Ubuntu Karmic on my sister's old computer for my nephew, he's quite young so my sister asked to install some content filtering. I'll first setup an OpenDNS account and I've installed and managed to get dansguardian and squid working on a virtual machine to try it out. so far it's working pretty well, but I need to secure it form the inside out.
I was thinking of blocking specific outbound ports so he could not bypass the proxy. because by default the firefox configuration can be easily changed. so I have a couple of questions.
1. is it possible to block outgoing ports on Ubuntu?
2. is that the best method?
3. is there anything else I should be aware of to prevent subversion?
lastly, this question is probably unrelated to this board but I've set up a cron job to update a dynamic ip with OpenDNS, the problem is that the password is in clear text in the user's crontab, can I play with permissions? is it possible to run the job under a root account and deny read/write access to a normal user?
What are the possible problem when Windows access the file from Ubuntu got Read Only even though have a full permission to read, write and execute the file? Ubuntu to Ubuntu accessing the file there is no problem only Windows got a problem.

View 4 Replies View RelatedI'm developing an application in which one user must run java software that I'm compiling as another user. I wanted to give user A permission to see the bin direcory of my workspace, which is in the home directory of user B. I was wondering how can this be done? I gave the bin direcotry full read/execute premissions, but since it's in my home directory user A can't navigate to it.
I know there are a few ways I could get around the problem but they arn't very elegant. I was wondering if there is a simple method for giving a user access to a specific directory without giving access to all the parent directories. I tried symbolic link but user A still can't access it, and a hard link to a directory isn't allowed in Linux. I don't feel like making a hard link to every single file in the bin directory, and I'm not sure that would work anyways, since every recompile overwrites them.
I have a windows 7 ultimate host machine, installed oracle virtual box on it. Made a iso image to boot fr fedora. All this is fine when the installation is complete, it asks for reboot. Reboot done. Then I went to terminal. Did a SU - root to get into the root. Then I did a firstboot command to enter information. I created a user for myself and at the end rebooted the virtual box.
When it starts up, it does not show my user. It just shows "Automatic Login" and it logs in as Live System User. Even if I try to switch user then it gave me a authentication failure when I enter the credentials of the user which I created. If I try to create users manually using system administration, the user is lost after reboot. I have tried all possible steps...as instructed on the net.
I've used it recreationally in the past but am now attempting to deploy an OpenSUSE LTSP server in my wife's computer lab at her school. really like to make it easy for her to give the kids instructions for the day via a text file/pdf located on the kid's desktop. What I'd like to do since there's 500 kids that she teaches is create a shared folder for each grade that she just drops the assignment instructions into. I'd like to avoid having to add a link manually in each user's /home/*/desktop folder, so is there an easy way to do this?
In case the above isn't clear...
1) Create folder on teacher's desktop that is set to share
2) Create a link on each user's desktop to enable them to access said folder
3) Ideally, all new users will have a specific folder based on which usergroup they belong to (1st grade, 2nd grade, etc
I'm trying to get a password in a bash script for mysql user creation. But sometimes a get a non-alphanumeric character(s) in the password, and mysql failes with that. I tryed with apg -EO0Il1`~!@#$%^&*()_+-=[];./{}|:"'<>? but failed. I tryed with sed 's/[^a-zA-Z2-9]//g' , but at that moment the minimum password lenght failed. I'm also fine when there is a better alternative then apg.
View 2 Replies View RelatedHello, I'm trying to set up a read only FTP user; basically, they have the ability to browse a particular images folder and download, but not write (or delete accidentally). I've got it set up so the FTP user logs in directly to the folder, so I'm good with that; but they still have write permissions. We have an application built in PHP that copies image uploads to this folder; it also resizes them in the same folder. So in addition to the main FTP user (me) who needs write access to this folder, whatever the Apache/PHP user is (not sure?) also needs write access. Is there a simple way to affect read/write permissions on a user level?
View 4 Replies View RelatedThis is my first post and there probably will be many more. I've used linux before for short periods but never really tried to learn it. I've decided that I want to study linux and learn as much as I can about it. I dont hate windows or OSX but I really like problem solving and using the command line. Which I used to love with DOS.
I'm going for a complete career change so I want to get certified in Linux by taking the LPI test so I can show employers that I have some computer certification(In Japan it really helps). Now, I'm studying commands and trying to do simple tasks(just playing now) but want to get into it more.
Question: What books do you recommend for a begginner with just dos and windows problem solving experience to start learning linux? Also, what programing language should I pick up a bit for linux?

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 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.

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.
I want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.
I'm on a network where I have the rights, but how do I do it? I've been asked to look up another user's aliases for reference.
