View 1 Replies View RelatedI've decided to move this question into a new thread since i haven't received an answer for 3 days. This question was originaly posted here: [URL]... I've already searched in google, however i wasn't able to find an answer that solves my problem... How can i change the umask on a per user basis so that each user can have its own umask to fit his needs? For example: I have four accounts on my system ex.
admin1 : admin,
admin2 : admin,
manager : stuff,
user : user,
-So now I want everything from the admin group to be by default set to 002 (so that every user that is in the admins group can have a full share (-rwx rwx r--) of everything that is created by the admins).
-Then the similar to the above managers shoud have 022 umask.
-And each of the regular users should have 002 or 022 or 077 it is up to the users choice.
I hope that i have provided enough info thorough the example.
this is my first real problem that I can't solve my self.I've a test samba share called "Share" and I've created three users:
-mones
-fsu
-fsu2

In my /var/www directory, I have everything set up with:
user: www-data
group: developers
directories: chmod 570
files: chmod 460
Everything seems fine. Users from the developers group can edit files and all, but now we began using the Git repository, and whenever a user edits a file (ie. Joe who is a developer,) file permissions get screwed again. Now they're:
user: Joe
group: Joe
directories: chmod 755
files: chmod 644
How can I fix this so permissions remain the same?
I am a new Linux user and have a question about the administrative authentication. When I am logged in as a user and I need to do something that requires root privileges the little password window comes up and I enter the root password. My question is how long are the root privileges granted for?I noticed that a few minutes after finishing checking out the firewall configuration tool and closing the window that I was still able to re-enter the fire wall tool and other administrative tools. How do I log out of the root privileges without logging out and then back into my account?

This is my scenario... I have a backup file (.tgz) with user and group information preserved in it. It was taken from a web server running Apache and MySQL. The files in the backup are from across the system and contain files from several different users and several system type accounts and it is key that when restored on the new server the settings are not lost. The problem is that the users on the machine the files are being restored to don't match the ones in the backup file. For instance both machines had a MySQL user but they have different user ids and there are several user ids that existed on both machines that belong to different users. This means there is no way to sync the users on the new machine to the ones on the old machine. I can find all the users files with the find command like this...
find /decompressed-backup-dir -uid 1050
or
find /decompressed-backup-dir -user tom
If, as I suspect, there is no way to do what I want with a single command then perhaps there is a way to pipe the results of the find command to another command to handle the ownership change?
I could do this with a PHP script but there are 4GB and tens of thousands of files in the backup so I don't want to use PHP or Perl but I would be happy with a shell script that could handle it.
I have a network set up that has been working for around a year with no problems but has now developed a login problem. The system was set up with a main server with all users on it and another PC located elsewhere that people could log onto using there personal login and password that then gained access to the account on the main server. This remote PC has now got the problem. When you try to log onto an account it comes up with the message "your session has lasted less than 10 seconds. If you have not logged out yourself this could mean there is a installation problem or that you are out of disk space."
Error message says that no profile for the user can be found and it couldnt create per-user gnome configuration directory. I can log on as root onto the remote PC as it is obviously a local account but all the account on the main server are not accessible. From the root account I can see that the connection to the server is OK and I can actually log into the accounts on the server using the failsafe session so the physical network is OK.
I never built or designed this set up and to be honest I normally work with windows so its all a bit strange to me. Both PC's run Centos 5. I have checked the messages log and there doesnt seem to be any indication of a problem. Just that it stopped connecting from the remote PC. The accounts are all active on the main server itself and have no problems being accessed.
I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

View 3 Replies View RelatedI made a mistake on my friend's Ubuntu system when trying to get hard drive permissions right. I wanted to add a user to a certain group with usermod -G, but without realising I should also use -a, with the result that the user is now not longer in the sudo group. This is the only (regular) user on the system, which means I can not sudo usermod again to get it right. So what to do? The only solution I can think of is using a live disc to restore the group belongings, but I want to know if there's a quicker way. Also, I don't know what more groups the user was in. Is there a history? Or else, what are the default groups?

I'm stumpeed as to what the problem could be.
I should perhaps add that the home directory is /mirror/cu (so that the users share the same account when mounted). Not sure if thats relevent though...
My /etc/exports file (on the server) looks like this

and I do the mount (on the node) with
