When I have different people log into our ftp and browse to the same folder, some people see the files inside, some don't. all the user accounts are in the same group, which has permission to this folder. but the one user who can see the files is the owner. how can i fix it so everyone in that group who's the owner of the folder can see the files?
I am using CentOS release 5.4 ( 2.6.18-164.9.1.el5xen ) and created an HPC cluster by using NIS ( for user authentication ) NFS ( as file system ) and mpich1 as parallel compilers and utilities and TORQUE as job scheduler. I want to make sure all users should use scheduler for job submission and should not submit the job directly ( qsub job.sh ).
I want to prevent all users from executing executable files created by self , from its home directory .
Suppose if a user create an executable a.out and if he tries to execute by ./a.out it should display an error.We should also allow users to execute normal user level linux commands .How can I implement such a set up in my environment
Me and 2 others are working on a website (Bob, Mike, and Joe). We made a group called developers and each of us are in the developers group. The Apache server runs as www-data. When we upload files, the file owner is the users name and the group is "developers".
/etc/group has the following
Code: www-data:x:33: bob:x:1000: mike:x:1001:
[Code]....
I have always just set everything to 775 and just called it good. Well I don't want to wake up to a Russian political message plastered all over the site. It's time I do things properly.
I installed proftpd on my Ubuntu 10.10 install. I also run multiple websites that I want to allow ftp access to for 2 different users. The websites are located in /home/www/. This is where the guide I was following told me to put them. I also don't have a user named www.How can I give write permission to upload, delete, and edit all the files in /home/www/ for multiple users? They can connect to the ftp server and see the file, just not change them.
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 have a file the owner is root:root ( mode is 644 ), I want to release read & write permission to a non root user ( eg. admin_usr ), I tried to create a specific group ( eg. ADM ) and release it to root user and admin_usr ( by adding this users to ADM in /etc/group ) , but it is not work, if preserve the file mode to 644 , is it ok? how to do it if I want to have read & write permission in my case ?
i want to set permission type "write" on a file to a particular user in a group of users ( not all users in that group). chown is changing a user to root , but i want to set say permission of "write" only to a user 1 in group staff which contains 10 users 1 , user 2 ...user 10.
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'm trying to do something like thisi created a group called www and made this group the owner of the directory/var/www/htmlso i can read and write to it.of course I've add my self to this group, but it seems i can't read and write.the syntax i used was something like chown :www /var/www/html.didn't workonly when i used chown samurai:www /var/www/html i could finally could create new file.the reason i don't want to specify the user name is because I'm thinking of a scenario when i need to give permission to a large group of ppl and don't want to do it user by user.
I've been asked by my professor to add the list of users to a linux server (not sure of the OS type I think he said debian) but anyway. He gave me this script to add users.
Code: #!/bin/bash # Script to add a user to Linux system if [ $(id -u) -eq 0 ]; then read -p "Enter username : " username read -s -p "Enter password : " password egrep "^$username" /etc/passwd >/dev/null if [ $? -eq 0 ]; then echo "$username exists!" exit 1 else pass=$(perl -e 'print crypt($ARGV[0], "password")' $password) useradd -m -p $pass $username [ $? -eq 0 ] && echo "User has been added to system!" || echo "Failed to add a user!" fi else echo "Only root may add a user to the system" exit 2 fi
I need to see if I can get this script to read a file that list the usernames and their passwords using the pipe command (or some similar command) so I can just do it in one batch. I've done some searching but there are so many vairiations of the code that I've confused myself. Also, I'm not too familiar with linux, it's been a few years since I've used it but in the prior script, I need to add the users to an existing group named "forensics". Which line would I change/add in order to do this?
how to map all domain users form group Domain Users to local group users (and maybe some more)? Im using Ubuntu 10.04 x32. Its connected to my domain using Samba and Winbind, I can login using my domain credentials, automatically map user folder form DFS server, but I think that domain users have too much priviledges in the system and want to restrict them as much as possible
I'm running Ubuntu 11.04 (guest) on Windows 7 (host) with the guest additions installed. I have an auto-mount folder that maps to my D: drive on the host which I can access using sudo ls /media/sf_D_DRIVE - however, even when my user (ross) is a member of the vboxsf group I get a permission denied error when attempting to explore it. I have restarted since adding my user to the vboxsf group.
This should work because I am a member of the group (which has rwx rights), so why doesn't it?
ross@panther:~$ 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
In other Linux distros I've used, new users are assigned to their own group (i.e. user 'joe', group 'joe') by default. To my surprise, when I create new users with my openSUSE 11.4, they are all assigned to the 'users' shared group by default.To test this, I created a new user called 'friends'. From my terminal, I can see how the new user files look like:
joe@linux:~> ls -l /home/friends/ total 40 drwxr-xr-x 2 friends users 4096 Sep 3 11:37 bin
I want to copy all directories, files, and hidden files and hidden directories with one command. I want these items to replace any same items in the target directory.
I have tried several things, such as:
cp -r * cp -aR *
but I only seem to get visible files and directories. Obviously, I am missing something. (A brain, probably....)
I need to test linux group permissions on a repository. In one shell, how can I temporarily remove one of my group associations? e.g.If my groups are defined as:
% groups foo bar baz
How can I make it so it only returns foo bar without baz?
a small lab of linux servers contains two servers. the administrator wishes to permit user settings and project files to be available when users log in on any machine descibe the server processes needed on the servers
I got myself curious on the possibility to change user's permission to any command, or at least giving other users some command line "power". It all started a few days ago, when another user here, had a problem so that the computer wasn't answering. So, after waiting a while, chose to hit the Reset button and start the computer again. Considering this situation, I thought myself that it would have been better to restart the computer, through command line, on any terminal (F1-F6). Anyway, this user is no administrator, thus wouldn't have permission to use the code...
So, is it possible to let other users to use such commands, in order to safe rebooting the system, without logging as root?
I'm having trouble breaking down permissions in linux. Here's the scenario. I have two users: UserA & UserB with each having to ownership and access to directories myDirA and myDirB respectively.
UserA --> /source/myDirA UserB --> /source/myDirB
I need to set the permissions so that userA can access myDirA and myDirB. There are other users and directories but they should not be able to view outside of their own directories (which is the way it is now). I don't have groups set up for them and I'd rather not change anything else but just the permissions.
rwxr_x_r_x UserA rwxr_x_r_x UserB
They're read/write/exec permissions are identical.
I had Windows on my machine but I decided to try Ubuntu 11.04. I kept my partitions where I store music, movies and stuff and it is OK, I can open anything, but I can't open the files that were in a hidden folder. I see then, I can browse my Windows hidden directories, but I can't open the files!
I am using ubuntu 8.04 and have a separate home partition. While setting it up I had a few failures and was left with several directories containing many hidden files which I can't seem to delete. The man pages for 'rm' didn't seem to provide the answer either.
Is there a flag or escape sequence that will allow 'rm' to delete these files?
Is there a way to make the system display hidden files in the home folder when you open it? I know you can select "Show Hidden Files" in the view menu but having to do this every time you want to see or access hidden files and folders is annoying!
