i have created a file (by root user) called test.txt. Then i created a user bob. Now i want only bob to read/write/execute this file and no other user shall have any permission on it.
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
I have two machines between which I need to share a folder.On server1, I have the user 'appuser' that needs to access (read/write/delete) on this share.On server2, 'root' accesses this share and writes to it.I have the following in /etc/exports on server1:/home/app-share 999.999.99.99/28(rw,insecure,sync,no_root_squash)where the number is the IP address. How can I change this to allow 'appuser' access?
allow specific user permission to read/write my folder
I have a folder called /TAR/Sketch
I added a new user, named Snoopy, I want to grant this user the ability to add files & directories to this folder which is under the group Sketches and the owner is me.
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 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.
Last weekend i have increased the open file size (ulimit -n) for the application user id i have update the limits.conf file with necessary inputs restarted the service and the server as well, when i check the ulimit value for the specific user by switching user from other user it shows the new value (10240) but if i login directly using the application id the ulimit value shows as 1024 which one is the default one.
my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
I have a need to run a specific app as a specific user when the machine boots into init 3. I can not run this as root so I need to specify a user. Can someone tell me how to accomplish this?I usually have to log in and start this application by typing check -D which starts this app and daemonizes it. I want to be able to run that at boot with my normal user not root.I hope I explained this correctly.I have added it to rc.local but it runs as root.
I am looking for a way to deny telnet and ssh to one specific user. So far I've only tested with telnet and my attempts have been limited to various hosts.deny entries:
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain
So right now VNC is starting a session using :1. When I connect to that session, the terminal is logged in as root. I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.

Im trying to add users to my nfs server with a specific home directory that already exists. Can this be done? I've done some research on google and other forums but cant seem to find the answer.
I did some digging on the sudo command and I do know the config file is /etc/sudoers Read the manual for sudoers and found out that I must use visudo to edit the file I read some of the examples at the bottom of the file and tried entering my own account in following the example. one of the commands I was trying to allow my account to perform without root login is the mount command So I tried adding this in (kreid8 /bin/mount ALL) I then saved & exited the file and logged out of root and tried sudo mount -t vfat /dev/sdc1 /media. I got an error saying I had to be root in order to do that But when I use the visudo -l option it shows that I have that privellege. Did I edit the file incorrectly?

I'm trying to access a share across the net. the share is a disk "fat32" which I mounted using "vfat users,rw,exec 0 0." However, after I created the samba user "smbpasswd -a user" I'm still unable to access the share across the net. ports are open, and entry has been made in smb.conf for share. But I'm having problems giving permission to smb user. the share it is mounted on /media/share, and I've tried everything from
chmod -R ug+rwx /media/share chmod -R ugo+rwx /media/share chown -R user /media/share and I always get unable to set permission for user
I have configured samba server.My requirement was that the path which i have to share was /srv/www/htdocs.With this the shared path for developer user was /srv/www/htdocs/projects.
So in the smb.conf file i made the entries as following:
After that root user was able login to both /srv/www/htdocs and also project folder and developer was only able to login to projects folder.That was according to my requirement but now the problem is that when developer is trying to edit any file in projects folder he is getting error that you dont have permissions to change this file.But developer should be able to edit any files. What changes i need to do now.

Since I have never had the need to create one, the first time I encounterd it I asked myself: what is it?I was looking for MySql installation guidelines on mysql.com, when, reading them, I found this command:shell> useradd -r -g mysql mysql.Now, I read the man page of useradd looking for explanation about -r option, but I didn't found it useful.It just says that -r options creates a System account, but it doesn't say anything else.So my question is: what is a system account? Few lines under the command it says:"Because the user is required only for ownership purposes, not login purposes, the useradd command uses the -r option to create a user that does not have login permissions to your server host."What would be the benefits if mysql user has not login permission?

Many folders within a subdirectory some of which have lots of data in and some of which have only one specific file called produkt.fil inside.I need a command to find and delete those folders that contain ONLY the file produkt.fil - if other files exist (doesnt matter what they are) then they should be left alone. Note: produkt.fil exists in all of the folders always.
