Programming :: LPR Error - Scheduler Not Responding
Feb 9, 2011
I am trying to write a BASH script that will help people print on Linux Servers (CentOS). I am asking the file in the script. We use a print server That have specific named print queue/ports.
The syntax I am using is:
lpr -H at-test.college.edu:Test-BWQ -U test test.doc
and I get a "lpr : Error - Scheduler is not responding!".
[Examples used:]
Server: at-test.college.edu
Port/queues: Test-BWQ
user: test

I have made a vb6 porgram, it is running without any error in windows platform. However, i want it to be run at Fedora too. I run my program with Wine Windows Program Loader in a Linux pc, but the program stuck with an error message:
Run-time error '429':
ActiveX component can't create object
I thought it was the error message because of missing some dll/reference files, so I tried to copy all those related .dll & .ocx file into my wine file. (Just copy and paste into the system32 of wine, no regsvr32 statement to register the .dll as what we always do in Windows.) However, all my efforts are in vain. I not sure what is the cause of this error.

After I login to KDE I see an error dialog saying,"ESC is already running, but is not responding. To open a new windows, you must first close the existing ESC process, or restart your system."
What is ESC and what can I do to stop this error dialog from popping up right after I login?

Does anyone know what I can do to alleviate this Script Error?
Code: A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: http://[url]....
suddenly developed this Script Error over the last 24 hours... Also, it is way slow, suddenly, and graying out. Could that just be because I caught up my Comcast Bill yesterday ?

I recently got an SSD and want to switch to using the noop IO scheduler permanently. I understand how to change the scheduler at runtime, but where can I put the command to make it apply on bootup?
I know you can pass "elevator=noop" to the kernel, but that sets all the drives to that scheduler, which I don't want as I still have ye olde spinning drives too - I just want a single drive set to noop..
I'm guessing there's an init script somewhere which is ideal for this, but I've no clue which!

Is there a DEB of the 2.6.32 Kernel with the BFS Scheduler built in? I'd like to give it a run, but I'm not so sure about compiling it on my own.

When I try to schedule a task with kcron, It doesnt work. I installed it with sudo apt-get install kcron. Now it appears in advanced system settings.If I test the task with the run now button the task works correctly. However, when the set time arrives, the task is not performed automatically. I have tried both the personal user cron and the system cron.
By the way, when I try sudo service crond restart, It says service not recognized and when I use sudo contab -e, the file is empty. It should have something since I added an entry in the system's cron in the kde schedule manager.

I'm trying to run a command with the 'at' scheduler in Linux Mint 9. It's basically a ssh connection to my Smoothwall firewall to tell it to shut down, but that part isn't really important. The problem I have is that I can't get the 'at' schedule command to do much. I can type commands into the terminal and they work perfectly. If I enter exactly the same command into 'at' nothing happens.
For example, I can type 'plink -load smoothwall' into a terminal and a new ssh terminal comes up asking for my password to make an ssh connection. If I create an 'at' job with the same command, ie:
Code:
$ at now + 5 minutes
at> plink -load smoothwall
at> <Ctrl-d>
$
then nothing at all happens when the 5 minutes are up. I've checked that the job exists by doing an 'atq' command. Obviously there's something about 'at' that I don't understand. I've googled, I've looked in this forum and I've looked in a copy of 'The Linux Bible 2010' all without success. I've tried various alternative ways of entering the command for a couple of hours and I'm still stuck.

So how do I get real USB performance back? On older kernels, copying files to USB sticks, I'd get 30Mb/s. Struggling to get 4Mb/s now. What settings can I change?

I recently loaded ubuntu 10.04 on an older laptop to get a feel for using a GUI version. I would like to setup a recurring job schedule to start sound recorder or Audacity. I would prefer it was from a graphical user interface but would do it with a cron if I could get started.

I'm having a problem with Vuze locking up when I use the speed scheduler plugin. I never had this issue when I was using them in windows.
Here is whats happening. I have speed scheduler set to pause my seeds during the day. sometimes when it pauses a finished torrent the status of the torrent will be stuck on "stopping". When it does this my bandwidth up and down drop to 0 and I cannot download new torrents. I cannot removed the "stopping" torrent or even restart it. Vuze just kind of locks up. I have to kill the java process and restart Vuse before I can get it working again.
I'm running the latest version of Vuze and the speed scheduler plugin on Ubuntu 10.04.

Following VMware recommendations on how to change linux I/O scheduler for guests, I'm trying to do it on my VM machine running Debian Wheezy. At the moment I'm running kernel backports:
Code: Select all$ uname -a
Linux brutus2 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3~bpo70+1 (2016-01-19) x86_64 GNU/Linux
The default I/O scheduler at the moment for device /dev/sda is CFQ, and I can change it on the fly to NOOP:
Code: Select all$ cat /sys/block/sda/queue/scheduler
noop deadline [cfq]
$ echo noop > /sys/block/sda/queue/scheduler
$ cat /sys/block/sda/queue/scheduler
[noop] deadline cfq
[CODE]..

We make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??

as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

I the Linux kernel 2.6.32, The CFQ scheduler has been changed as you probably know. They insert the 'low_latency" mode in it.I read that this option, actually limits the affect of the dirty data write from the buffer cache while the system doing sync IO.
From url:
Quote:
"the amount of async writeback sent to the device will be limited by the time since that last sync IO." "limiting the damage that the async IO can do while sync IO is also happening"
I also read that this option is not recommended to Database server.As I know, DB writes his DB files with O_DIRECT and won't write to the Filesustem buffer cache.SO this option don't need do bother him.

I recently read about "at" and thought it was neat, so I wanted to try it out. Unfortunately, it doesn't seem to do what it's supposed to. I would type: at now + 1 min
Then in the prompt I would type:
echo hello
zenity --info --text="HELLO"
<Ctrl+D>
I confirm the job is entered with "atq" and sure enough, the job is there, for the correct time. When the time comes around, nothing happens, and the job disappears. I don't see any text in the console, nor do I see a zenity infobox pop up.

I downloaded quicktime from the apple website because I am trying to get Itunes for fedora (If anyone knows another program that is functional with the IPOD please, let me know), I installed it with WINE, but the program is not responding well with my box. The program doesn't open, instead it black-out my computer screen and when I move the mouse over things, they then start to appear. Anyways...I tried uninstalling all of the files and folders that include the names "quicktime and qt"...then I tried re-installing QuickTime. Now I receive a reply that states "There is already a newer version of QuickTime installed on your computer." When I try
Code:
[pgar23@python ~]$ locate quicktime
/usr/lib/libquicktime
/usr/lib/libquicktime.so.0
/usr/lib/libquicktime.so.0.0.0
/usr/share/doc/libquicktime-1.1.1
[pgar23@python ~]$
But when I search through the filesystem, those files/folders are not present... How can I completely remove this atrocious program?
