I have a new UEC (Ubuntu 9.10) server up and running. I'm running a self contained solution so the cluster and node are on the same machine. I know this isn't ideal but I only have one server. I followed https:[url]... and https:[url].... When I try to run a VM (Ubuntu 9.10 amd64) image it will go from pending to shut-down to terminated. I know others have had this problem but I haven't see any solutions. I'm hoping there might be one out there that I've missed. I'm running on an AMD 64-bit quad core with 8GB DDR3 RAM.I am not seeing any errors in the logs.
I have a test server on which I'd like to run up to 30 separate instances of a program as daemons, each running on a different IP address bound to the server. I've created a init script that takes an additional command line parameter - the last octet of the IP address. For example:
Code:
sudo myprog 40 start sudo myprog 41 start
This would run instances of the program on IP addresses 192.168.1.40 and 192.168.1.41 respectively. But it's looking like this approach isn't doable if I wish to have any or all of these run at startup, as the links in the rcN.d directories can only link to the init script, not pass a parameter.
I've got two sound cards fitted, before I've always killed pulseaudio as a pain in the butt.
Without pulseaudio enabled I could run two audio apps simultaneously, ie run a SDR ( software defined radio) app , and listen to music or watch TV at the same time.
However, with puls audio running, you can only run one, either input to either output. So can a second instance of pulseaudio be run, master and slave perhaps ?
I've installed Ubuntu 10.04 LTS (64-bit) server edition on a box here (a few times now), and each time I attempt to boot post-install, I get RAID errors. The box has 4 hard drives in it, and I've disabled the hardware RAID in BIOS because I couldn't seem to get that to work.During the installation, I opted to handle partitioning manually. One set of hard drives has two partitions: one for swap, and one for /. When all is said and done, I end up with three RAID 1 mirrors: one for swap (/dev/md0), one mounted at / (/dev/md1), and one mounted at /srv (/dev/md1).
I am a novice in the world of cloud and recently managed to configure Ubuntu 9.04 Cloud (using kvm, eucalyptus and other packages) successfully at my college for my project work. The problem is that i can only manage to view the running instance using rdesktop from any remote machine. Is there any way to do this other than rdesktop/logs? Secondly, I want to develop a application on the lines of google docs as a part of my project. Is it possible to install apache server on this virtual instance, and host a website? How will the client access this website? Which frameworks would be required or do I have to develop one?
i started to look into upgrading my LTS ubuntu server instances to Lucid. one the notable things that i have discovered is the lack of support for Webmin; it seems that Debian is no longer supporting packages required by Webmin. But it also appears that ubuntu team believes that Webmin may actually cause problems as it works in a different way than that presumed by Ubuntu. so i am now left with no way to manage my 10+ instances of ubuntu server that i used for studying and research. it seems that i am left with cluster-ssh as an alternative. but are there other alternatives, ideally similar to webmin?
I have a script to establish a reverse tunnel with other machine,My problem is to stop the tunnel. If I just kill the PID at sshtunnel.pids, ssh does not release the ports at the server side, so any new connection will fail for several minutes.Is there any way to signal SSH to exit gracefully?
I have a machine running Fedora 14 and a bunch of movies stored on it as '.iso' images. It is connected to my home theater. I used to use VLC to play these movies and it worked great for a long time. About 4 months ago, about an hour or hour-and-a-half into a movie, the audio suddenly "disappears" and the machine goes CRAZY with almost 100% of the CPU spent writing to the SWAP. At first I thought the machine was locked, but it isn't; it's so doggone busy writing swap. I am unable to get enough cycles to terminate anything. I found the swap activity through System Monitor - it was ABRUPT. Sound stopped, machine became preoccupied with swap.
I have removed/reinstalled VLC, the machine has undergone a couple kernel updates, and I have removed/reinstalled a number of things associated with audio (CD ripper, mpeg stuff, etc.) yet the problem persists. I don't know what happened or when (update-wise). Any body got any ideas? While a solution would be great, I'd also be happy with a couple decent suggestions on what to look for.
Just now Rhythmbox has stopped working. I can't restart it, so I thought I could kill the process to start it again. Is there something like the windows task manager in openSUSE or another way to list all processes and to kill one? I googled an found a few old threads saying that there is a performance monitor which is able to to that, but I can't find that either.
done so the script waits in the loop for the subshell to finish then does processing and starts over. If I kill the script the subshell is not killed. So I can trap the TERM event and do some cleaning but I need to know the subshell process id.
I'm using busybox so ps does not accept any parameters I cannot source subshell so it can access its parent environment
I have an issue with my web server. We are running RedHat Enterprise Linux 3.0 with Apache 2.0 and Tomcat 5.5. The situation has arisen that the httpd sessions never terminate. New connections continue and continue to be created and never die. I have restarted the apache services to reset the connection and have even rebooted the server, however, to no avail. Yes, that does the trick of getting the web sites operational, however, this is not a solution.
I have searched and searched here, www.google.com/linux to no avail. I have looked through the apache.org bug tracker and can't find anything like what I am experiencing. This happened 6 months ago and I got lucky and it stopped, however, the situation has resurfaced. I have reviewed the logs and found nothing that provides any insight.
During the business day, the number of httpd connections continue to grow and I decided to let it see how high it would get before the web sites would crash. That magical number is 203. Now that it is later in the evening and about 2 hours since I restarted the httpd services, I now only have 59 connections. However, I'm fairly certain based upon the traffic on these 2 websites, that in the evening, there aren't many connections after 2000 hours.
I'm using tigthvnc server on linux machine. Often my clients are closing their vncviewrs from close button ('X'), and not exiting gracefully their sessions from OS. How can I terminate the server when they do that?
I am having an issue with HTTPS certification using curl. My curl is configured with OpenSSL. If the certification verification is failed I dont want to terminate the operation, instead I want to continue by just putting a log message. For this I have used OpenSSL SSL_CTX_set_verify() function to set my static C callback function. During HTTPS transaction, my callback is also getting called with first parameter 0 or 1 (depending upon of the certificate verification is success or failure). But even if my certification verification is failure, I want to continue. So I have hard coded to return value as 1 always from my callback function. But still I see the certification error and I don't get the page.
I have problem with sshd server, its authenticate user and then terminate the session.

but while trying to run with large data ie x = 5000000 approx it is giving error Even the first line of the code is not displayed. NOTE: variable is declared global but its size is defined in main.
The error that i am getting after approx 2-3 minutes is:

In Fedora 13 64 bit, Ctrl+C does not terminate the running programing in terminal window but in Unbuntu this shortcut key works. If I hit Ctrl+Z, this makes the running program run in background which is something I definitely dont want. what is the shortcut for terminating a program in terminal window? What is the shortcut key for canceling the command I have typed but not run yet no matter where the cursor is in the command ? Ctrl+U works but only if cursor is at the last character of the command.
I am running KDE 4.4.4 Stable from the openSuSE Repository for KDE 4.4.4 stable as included with 11.3.At first after initial installation Kontact worked and I could access Email, Address Book, Calendar, etc. from the icon bar. Now, Kontact starts, opens the Summary page, but no selections respond, only the Kwin responds to terminate the application, it just seems to hang and has to be killed to terminate. Anyone have similar issue or ideas on what may be causing it? I can start KMail, Kaddressbook, as separate applications and all respond as normal.
when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes
I have a BASH script which at one point asks the user a yes/no question. I want to make it so that if the user types in an invalid input 3 times consecutively then the BASH script will echo an error and terminate with exit status 1.
I have a serious problem with my Ubuntu installation (in a VM). In virtually every case where I try to access the command-line (Terminal, logging in directly into shell), I am not getting the command line. I get a blank line, and anything I type in results in the following text being replied:
"WinSCP: this is end-of-file:0"
I know what WinSCP is, and I'm not using it at all. And the result is that I can't run any command-line programs or commands anywhere within the VM anymore.
Both the VM and the host computer have been rebooted multiple times. I actually hadn't edited anything in the VM in a while, and I came across this issue while needing to fix another issue...
Somehow I'd been locked out of my OpenSSH access on the host computer (Windows Vista), and while troubleshooting that, I found that someone was trying to hack into SSH with random password attacks. I haven't noticed any suspicious activity otherwise (no missing files, no malicious programs, no traces of a hacker) but after looking at the logs on the Ubuntu VM, it looks as if someone was trying to get into that computer as well. The only fishy thing I've noticed is the command-line shell issue on the VM.
So, now that I've turned off SSH and I'm trying to get Ubuntu fixed... what can I do? Did some hacker get into the Ubuntu VM and set up a shell redirect or something? Or is this a more innocent or easily fixed issue?
I have multiple hard drives with videos on them and i can only get the my xbox to read the 1st in my list of directories. So i wanted to know can i run multiple instances of ushare and use one for each hard drive? Is it possible?
The great clock applet shows tasks and appointments from the evolution calendar. That's a great and fast overview of my agenda. But clicking a task of appointment opens a new instance from evolution every time, which is enormously annoying and really destroying productivity. I don't want 15 calendars open, I want the applet to behave like an index. So it should reuse the open instance and bring focus to the clicked appointment or task. How do I disable multiple instances of evolution?
For some reason, since logging in recently, I've got 2 instances of the Broadcast in the messaging menu. One of them is indicated as running, the other one is not. When I select the one that isn't running, a *third* instance of the Broadcast button appears - so I now have 2 running, and one not running in the messaging menu. In the usr/share/indicators/messages/applications folder, I have 3 files - Gwibber, Empathy, and Thunderbird.
I tried the google and browsing the known bugs in the sticky before posting this thread.On boot the machine is pegged at 100%. It is a dual-core with 4GB of ram and is running 10.04, 64bit. Also, as time goes on it eats up all the ram till theres maybe 32mb free. What happens is there are multiple 4-10+ identical processes running. seem to be gnome related.The machine sits idle on my floor and runs samba and apache/mysql/gallery for my test website that no on but myself visits.
