Ubuntu :: What Running Process As Root Actually Means
Apr 8, 2010
I just installed Wine (1.1.3* dev release) and installed Notepad++ (OSS) and Net Meter (Freeware, the latest beta is actually OSS too). I also intend to install a few other things later. The only failure so far is the latest WinSCP So it made me wonder about what running a process/software as "root" actually means. When I use U.S.C or 'apt-get install' to install software on my computer, and type my password, it displays that keyring icon on my systray.
Does this mean I am root at that moment? And how about running wine, the wine processes, and any windows *.exe I'm installing and running? I basically am afraid that I am running all the wine-related stuff as root, even though there is no indication that I at least have elevated privileges. What is/are the worst-case scenario(s) about wine?
I am trying to set the umask for a process(orkaudio) which is running as the root user.This program creates dir and files and I need the umask to be 022. I have edited my /etc/bashrc -- and when i type in umask i get 0022 --- Not sure how to go about getting this resolved...
Is It possible to change a process running in root-user to non-root-user by setting suid / uid / euid / gid etc... I so please instruct how, when and wat to set in order to change a process running in root-user to non-root user
In the boot process of Linux we have the initrd that is a root file system and is mounted before the real root file system become ready to mount. What is the procedure of mounting? What should happen so we can say that file system is mounted? And another little question why we say ¨root¨ file system instead of just file system?
Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
want to run VirtualBox with root permissions. Trouble is that only when run as root i can access attached USB devices inside of a virtual machine, otherwise, these a greyed out).Now running VirtualBox as a root user also changes the configuration folders, making all my virtual machines already defined disappear. I also don't want to copy all to the root configuration folders. Is there a way to give the VirtualBox root permissions but without actually running the application as a root user. Is it possible to do without changing the permissions of the non-root user, i.e. i don't want my user to have all root permissions, due to security considerations.
Is suid disabled from running all home made bash scripts or just from running them as root or:
Who would know for sure.
I googled several combinations of Mandriva Linux how-to suid disabled setUID etc... so far all I found was "many distributions are disabling suid for security reasons" nothing specific.
I recenlty set up a headless linux home server by my router will my spare computer parts. I have NFS and even a COD4 server running on it for my friends and me. Because the box is headless, I take controll over it with ssh and start the COD4 server from there, but the problem is, if I close the terminal I have the ssh running from, it closes my server, meaning my desktop needs to be up and running the entire time. That kinda ruins the point of my server
So my question is, is there a way for me to run the command so that it will not close with the terminal AND that I can still send commands to the server.
If I run top, there's a process plymouthd always running, often taking a few percents of CPU. I found that "plymouth" would be a splash screen. My PC is booted already though, I don't need a splashscreen once it has booted. Is this a bug? How can I get rid of this process that always uses %CPU?
Maybe someone can shed some light on this process that is running. It is using my CPU about 100% since there are 2 instances of it running with about 50% used by each.abc_sieve_2.10_i686-pc-linux-gnuI've never noticed it running before and don't think I've installed anything except updates.
I have what I hope someone finds to be a simple problem. I am running a data acquisition computer for a research project, where multiple people use the same non-privileged user account to take data and save it to /incoming. Once the file has been closed, I would like to somehow copy the data into a more permanent location owned by root. Obviously giving the shared user account sudo permission would be a huge security hole.
I know that this should be possible using some sort of client/server connection, but writing my own server just for this little task seems a bit cumbersome, and is something I have no experience with. Nor have I ever written a daemon/init script before.
Does anyone have any ideas on a simple procedure I could use? Very few things are fixed in stone, but the copy operation is necessary - the final location is a RAID5 array, and the write speeds are too slow to keep up with the data stream.
If a client/server type of thing really is the best way to go, anyone have any links to good tutorials to make a simple server and daemonize it?
Firefox keeps freezing.the process keeps running.I've uninstalled firefox, installed different versions, ie 3.6, 3.7 etc, I've removed my profile folder in my home directory.same results. I've ran firefox as a SU and I get this output from the terminal
(firefox-bin:28892): GLib-WARNING **: g_set_prgname() called multiple times /home/josh/.gtkrc-2.0:2: error: scanner: unterminated string constant - e.g. `style' (parent won, so we're not deferring)
I installed Gnunet (a secure P2P program) on Ubuntu 10.10 using Ubuntu software centre but had difficulties getting it to work so removed it. However, the gnunetd process loads at startup. It is only visible when typing 'top' in the console and not in the system monitor list of processes.gnunetd --version tells me that it is 0.8.1b sudo apt-get remove gnunetd tells me 'unable to locate package' why the process loads and how to remove it? I can kill it in the console but would like a way of getting rid of it permanently.
i am using Ubuntu 10.04.1 LTS. i only ever contact my ubuntu machine through SSH. everytime i login, i do:
~/downloads/.dropbox-dist/dropboxd &
this launches the dropbox process and all is great. except when i log back into the ubuntu machine via ssh after a few hours, the process no longer exists. how can i get the process to run indefinitely?
I am trying to write a script that will look for a plugin and check that its running and if not start it Code: ps ax | grep -v grep | grep aseco.php The above should list the process, if I put it into terminal this is incorrect?
how to configure X11 forwadring over SSH so, that when I open any app over SSH, I get displayed window of a process that is already running on my server (in case its running ), not a new instance of it.
I've just installed Unison. I created the default profile, selecting one of my subdirectories as the source. That done, the GUI disappeared, although a unison-2.32.52- process remained running. I can start another GUI session and, regardless of if I kill the old process, I can only choose my profile before the GUI disappears again. There is no opportunity to do anything else useful, such as selecting a destination directory.
There is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code: gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code: echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code: echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?
I am writing network module (LKM). I got process information by current->pid and current->comm. But now i want current state of task. I want to know the state of running the process. I dont find any information in struct task_struct structure. how can i get the state of current running process.
How can i get the notification of process which are currently running?
We wrote one script which is being fired for every minute, instead of that is there any to trigger the event from linux core implicitly if there is any change in my process(pid)?
I have not been able to find any information on this, mostly because I am sure I am searching for the wrong terms. Let me explain what it is I need to do.I have a timeclock process that needs to be running all the time on my Red Hat server. Right now, I manually start the process from terminal:Code:# ./timeclockThis runs the process inside the terminal. The only problem is that if I close the terminal by accident, the timeclock stops working. This is all well and good for now, until I get more timeclocks.Then I will need to have one terminal open per. What I would like to do is to make this process run at start up, and run behind the scenes (no terminal). At the same time, I need to be able to re-run the process (again, hopefully behind the scenes) in case the timeclock goes offline or the process crashes.I know very basic things about Linux administration, and I know it is possible to do this (as there are processes now setup by someone else that do this), I just do not know how. EDIT: An idea I had would be to make the script run every minute, checking to see if the process is already running, and if it is not, then to start it. That way it would automatically correct itself if it went offline.
Using Ubuntu 9.10 I open up Firefox and run a video from ......com web page. How can I monitor if flash player is running using terminal ps (process) command? What is the flash player process name?
