I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."
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.

The company I work for has a Linux server running CentOS 5.4 Company uses Linux for their Email, FTP and Web Server. Have been here a few years dabbling in and out of Linux and now that the old Admin has left the company.....I need to learn it ASAP. The server has run pretty solid until today.
The email server runs SendMail and SpamAssasin. Received lots of complaints today regarding extra SPAM. Noticed that SpamAssassin was not running. Tried to restart it through the WebMin tools and got the following error: Starting spamd: child process [3956] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588.
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?
View 2 Replies View RelatedMaybe 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.
View 6 Replies View RelatedI 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 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.

View 3 Replies View RelatedI'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.
View 5 Replies View RelatedThere 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.
How do I pass text to an already running gomoku?
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?

View 12 Replies View RelatedI 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.

View 8 Replies View RelatedI'm running a pretty heavy-weight process (Rails tests) that involves several worker processes, in an effort to parallelize the runs. To measure the performance impacts, I run hdparm -T /dev/sda to give me the cached read performance. Note that the disk IO is not being measured, but the disk cache IO is. It works very well on my work machine (8-core Mac Pro running Ubuntu with 8GB of RAM).
The baseline is:
honk4:~ $ sudo hdparm -T /dev/sda
/dev/sda:

I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?
