General :: Execute A Command On X-session Owned By Another User?
Jul 13, 2011
Is possible (by root of course) to run a command from console, that will be executed on X-session owned by another user on the same linux box/machine ? Example: Can root open xclock for another local user logged into X11 ?
I am trying to write a perl script which will give an interactive session to a user to execute command on the server. I have written a small script to do this :
Code: !/usr/bin/perl -w use strict; use Net::SSH::Perl; my $host = '192.168.1.1'; my $username = 'user'; my $login_passwd = 'test123';
I'm trying to jail a sftp user. All I want is for my daughter-in-law to be able to download pictures of my grandson on his step-uncle's motorcycle. But I don't want her browsing around. She's not a techie, but she's smart enough to catch on how WinSCP is looking at my files. I've set up the jail using jk_init, adding ssh, sftp, bash, netutils, basicshell, jk_lsh.
The physical root of the jail is owned by root, as are all the binaries loaded by the jk_init. The user's home directory is owned recursively by the user and is writable only by the owner. The passwd and group files are in the jailed /etc and populated by the user's lines. Shell is bash, and bash is there too. The error message must be coming from some other problem that's not notifying, but what?
I would like to give a non-root user (nicollet) the ability to detect and send a signal to processes started by Apache2 (those processes are FastCGI scripts and the signal tells them to empty their cache). The processes are owned by the web user (www-data), and I'm running on Debian unstable.
I can't find any way to have the nicollet user see those processes.
The processes are running and can see by both root and www-data:
The most surprising is that the grep process is indeed run by www-data (because it's started from a setuid executable) and is visible, but the baryton process isn't.
What's going on here? Why can ps run by www-data show those processes, but ps run by a setuid executable running as www-data cannot, when it's started by nicollet?
I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
I am a linux newbie. I have a situation where I need to send a command line -X command to a screen session owned by root from a nonprivliged account. The command is executed by a shell script, which in turn is executed from a PHP script. Is there a way to make this work?
Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:
Code: Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1
I've looked everywhere but I can't find where to change the default box for incoming mail, or am I on the wrong track. It's a nuisance having to change folders and I can't configure wastebin to empty on exit.And I can't get kmail to import from evolution. Do I have to go to the evolution storage and do it manually, and if so, how do I do that?
Is there a way to execute some command and then after the command completes utomatically reboot the system and then after the system reboots execute another command ? For example look at the sequence shown below(1) Execute command-1(2) After the command-1 in (1) is completed,reboot the system (3) Execute command-2(4) After execution of command-2 reboot the sytemIs there a way i can automate this process so that i need not reboot the system manually
I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.
I have just installed an SSD as a secondary hard drive and formatted as ext4. (the Ubuntu installation is on a different drive)how I would go about creating a directory on the SSD that is owned by the user 'Test user'.
I've setup a Moodle server on 9.10 server, and have been able to share user folders back to the windoze machines on the home net. What I'd like to do is share the Moodle main folder (and descendents) likewise. The problem is that it's owned by root. For ther user folders, as long as the owning user was logged in they were able to mark the folder as shared and everything worked very smoothly. When I try to mark the moodle folder as shared, no suprise I get a permission error. Is there a way of doing a "sudo su" from the GUI desktop to allow this to happen? Or do I have to set up the share from a command line (after having done a sudo su)? Can anyone give me the magic commands needed to do such?
I have just installed an SSD as a secondary hard drive and formatted as ext4. (the Ubuntu installation is on a different drive) Im very new to linux, Could someone inform me how I would go about creating a directory on the SSD that is owned by the user 'Test user'
Im sorry if this is a daft question, im just moving from windows to linux and struggling a lot.
Running 9.10 now, I'd like to do a clean install of 10.04 on my dual-boot (with XP) Compaq notebook. As a test, I burned an ISO image onto a 1-GB stick and booted to 10.04 from it. It works just fine, except that the directories in the Documents folder on my hard drive are owned by "user 1000", and "he" grants me access to only about half of them.
Is this problem likely to persist if I actually install 10.04 rather than just running it from the stick? If so, what can I do about it? Second question: am I correct in understanding that if I still need to access my Ubuntu partition from XP, I'd better stick with ext3 for this install rather than going to ext4?
I'm using the IDE Netbeans (text editor) on my /home/michael Ubuntu account. I'm trying to open a file with Netbeans that's owned by root, I can't do this as I expected. So is there a way to run NetBeans as root, or is there a way to give netbeans permission to open/save files owned by root
the script should take as input in the begginig the username of the user and then deletes all the files and folders from the user in every place he has them. script must also check if the parameters have been given correctly (only one and that one must be a username) Doesnt all the files of a user exist on a folder with his name? what if i delete this folder? Will something like this work?

I want to allow a user to reset people's faillog. When I go into the /etc/sudoers file and put this syntax in I still get an error stating : /var/log/faillog permission denied.
i was wondering if it is possible to run a program such as firefox or any other internet program as its own user (ie user firefox), but still in my desktop session, this way the program would have its own home folder and store all the data there, while i use it normally, i was trying to set the suid on the firefox binaries but then it doesn't starts at all.
Customer asked me to create a menu for linux he also asked me to do this: Open like a command like where a user can execute commands...so for this the users have sudo enabled. The code below works OK. But it has an issue when a command is executed but the command does not need sudo
Like for instance Code: cd / sudo: cd: command not found
How can I allow a user to execute all commands when a command does not need sudo Code: echo -e "Press Control+C to finish" #echo -e " " while true; do read whichcmd?"Insert Command: " sudo $whichcmd done
I am trying to write one script. Purpose of my script is that it will login to particular user and it will execute some set of commands.What I was trying....
I recently installed Suse Linux enterprise Desktop 11 on my box. I created an user and logged in first time into a GNOME session without any problems. Last time I logged in I selected the session as TWM and that got me into the T windows manager just fine. Now when I log out and try to log back into a GNOME session, it will still log me into the TVM sessionI have tried restarting the boxHowever, when I remote log in to the machine it will let me get on the GNOME session just fine. I'm guessing this is probably a really simple fix, however I am a Linux newbie and doing a google search isn't yielding me what I'm looking for.
Outside of using something like screen, is it possible to 'assume' an active user session under Linux/UNIX?For example, I ssh to my server from home. Then I ssh to it form work. I want to kill the home-spawned session, and "take-over" all of the processes that it had running.
I want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).
How do I set up SSH so I don't have to type my password? i execute the following command ssh -l admin hostname command but each time i execute it, it ask me to enter password.how i can give it password as default because i'm going to put in bash file ?
I am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.
The problem
I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user
The Question
Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?
