Red Hat / Fedora :: Enable The Use Of The Binary Gpg For Specific User
Jun 18, 2010
I have installed gpg (GNU privacy guard) Now I have done this in root and therefore it was installed in the folder /usr/bin/gpg Now my other non-root user accounts have all functionality except main ones (ls, mkdir etc...) disabled. I require more functionality on this websever, especially to enable the use of the binary gpg How do I enable these commands for that specific user? I have tried to figure this out for so long,

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.

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 very peculiar issue - I can't log in to KDE as one particular user (andrew, which is my regular account) though all other users including root, mythtv & other family members can log in without any problem. When I try to login as andrew the X server appears to crash as the screen goes blank and I have to press Ctrl+Alt+BkSp to get back to the KDM login screen. The proximate cause seems to have been updating KDE to 4.4.5 using yum - I did this logged in as andrew in a terminal session using su - root, and the black screen problem arose next time I tried to log in.
I can log in OK as andrew using a different desktop manager e.g. Sugar. I am using radeonhd graphics driver; if I change to "vesa" in xorg.conf I can log in OK. If I change the home directory for andrew to that of another test user and change the file ownerships, I can log in OK. Therefore the problem must lie in a config file(s) somewhere in the andrew home directory tree, which is specific to KDE and also radeonhd. I have checked in all the obvious (and unobvious) places but can't find anything. There are no relevant SELinux errors or entries in syslog or Xorg.0.log. The .xsession-errors file from a failed login attempt is here [URL] it isn't significantly different from a normal one, and as the entries are not time-stamped I am not sure which ones arise during the login and which when I restart the X server. I am running F13 (kernel 2.6.33.6-147.fc13.x86_64) without any other significant issues.

I've recently installed x64 Linux Mint 11, basically Ubuntu Natty. Since the install I've found that 32-bit applications which used to run on my Ubuntu system are rejected by my Mint 11 system. When I use the 'file' utility to check the binary, it correctly identifies it as a 32-bit elf, but I can't invoke the application. I've tried starting it from bash and os.system a la python, to no avail, so I suspect that it must have something to do with 32-bit binary compatibility mode but my knowledge of that sub-system and how to enable it is limited, can anyone assist?

It appears that a write protected socket was established as a symbolic link between an audio file and the binary of the audio itself.
We are unable to remove the files and the holding folder. Attempted all possible combination of RM that I could think of and then graduated to shred. We are unable to do so code...

I have this very weird problem: I'm not able to SSH to 1 specific server on the web. I can access everything, but not that specific server.
When I try to SSH, I get this code...
When I reboot to Windows, I can SSH using Cygwin. I'm using Ubuntu 10.04 Lucid and OpenSSH client 1:5.3p1-3ubuntu6.
I tried sniffing the network with Wireshark, but I cannot understand why the TCP connection cannot be set up. I'm sure it's an Ubuntu problem as I'm able to connect to that server on the same machine, but different OS.

Because I keep a lot of data on a Netgear ReadyNAS which can be presented as a NFS server, I would like to have the default CentOS user have a uid and gid that match those for the user that owns the main NFS share. That way I can treat it as if it were a directory that I owned on the local machine. I'm probably going to install CentOS 5.3 over again to get a totally clean system. What is the neatest way to ensure that the default user has the desired uid and gid? Or is there a better way to work with the NAS? (Right now I'm running it with CIFS shares, but these are quirky and do not behave quite like a local file system, I'm hoping that NFS would be more consistent, but previously attempts to run NFS were hampered by different uid and gid values).

I'm working on a kiosk-type system. What it needs to do is boot, auto login as a specific user, display only the Gnome desktop (no icons, etc), and auto start an application.
Is this possible (I'm sure it is)? If so, can this be scripted, i.e. without having to use graphical tools like Sabayon.

we are in a place where we have to give an account (with sudo access...) to a user we don't completely trust (I am reminded of this comic). What we need to set up is some way of logging pretty much everything that this user does, especially what he does as root (via sudo or sudo -s). Now, I know that anything we do can easily be undone by another user with root access, but we feel that if he does disable logging we can use this as a really good excuse to revoke his access. So, does anyone know what logging stuff I'd have to set up to completely monitor one user (it is ok if we are monitoring everyone, but we'd prefer to watch one user if possible)?

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:
in.telnetd : user@server
in.telnetd : user@server.domain.com
in.telnetd : user@IP_address
in.telnetd : user@.domain.com
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.

i wonder, why nobody has written about it ...
How can i grant permission for files to specific user or specific group ??
Updated:
We have 3 groups: "g12" ("u1" and "u2), "g34" and "g56".
"g12" should only read the file.
"g34" should write and read it.
"g56" should have all permissions (rwx).
And others should not access the file at all.

I just set up my own server and basically my folder is on say /media/disk1/ and my girlfriends is on /media/patato/ is there a way i can set it so that if i log in it goes to my folder and if she does it goes to hers.... I've currently got it set up as /media/ that it goes to but i cant get it to change it for each user (we can also browse each others drive and we dont want that, we want to be tied into /media/ourdirectory and all of its subdirectories) problem is that it is running on a computer that use to be functional (same install because I cant find my disk drive) so it cant use home folders....

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?
