• Why cant i install ANY operating system??

  - by Ranhiru

  I tested the memory and i tested the hard disk and everything is fine! Mini XP booted from Hirens Boot Disk works :( I tried Windows 7, Windows XP SP3 and even Ubuntu 10.04 :( All Operating Systems boots up to the point where they can load necessary files to start the OS and then resets the laptop Windows 7, only up to the point where the Windows Loading Animation is happening Ubuntu, only up to the point where the loading is done, shows a small screen and then goes to a blinking cursor and thats it... it keeps on blinking and sometimes resets the computer Windows XP SP3, loads all the drivers and everything and then the point where i should be able install the OS, it simply resets the laptop :( I have used the word reset instead of restart because the laptop completely turns off and then only turns back in Any solutions would be greatly appreciated

• What is the meaining of "deassert" in this context?

  - by Sam.Rueby

  The English majors over at Dell provided me with this error message provided by a PowerEdge 2950. CPU2 Status: Processor sensors for CPU2, IERR was deasserted I've Googled it, random forum posts aren't providing me with a clear answer. It's also apparently not a word: http://dictionary.reference.com/browse/deassert?s=t I can guess the meaning. Assert: to state with assurance, confidence, or force Okay. So the negative of that. The state of lack-of-confidence? What is this error message trying to tell me? Memory errors were grouped with this one: is it trying to say that IERR for CPU2 should be set, but is not? That the current system state is SNAFU but CPU2 sees everything as fine?

• linux recommendations for older pc

  - by jdamae

  Hi, I'm new to Linux and I am interested in installing the OS on an older computer I have. I want to setup a webserver and install php, perl. My pc is an older HP Pavillion a255c, Intel Pentium 4 with 512ram. I will probably add some more memory later. This pc is more like a sandbox than anything, but would like to get quickly started with the OS. Is there a particular flavor of linux I would need to download based on my older computer? Any recommendations? I was thinking about Ubuntu but not sure what version to go with. Thanks for your help.

• Apache mpm-itk Performance

  - by Matt Beckman

  I manage a bunch of VPSs with memory ranging from 1GB to 8GB. Most of these websites are Joomla websites, and the servers must support multiple sites/users/S-FTP. I use mpm-itk almost exclusively (mostly due to it's convenience in these shared environments). However, I'm aware it isn't known for performance, so I need some advice on making it faster. Due to the lack of documentation when I first went the way of mpm-itk, I included only one setting in the config, and that was to limit each user to 50 clients (the rest I left up to defaults): <IfModule mpm_itk_module> MaxClientsVHost 50 </IfModule> Are there any better alternatives available? Are there any settings supported in mpm-prefork or mpm-worker that are also supported in mpm-itk? Thanks!

• What settings to use for fastest reloading of a MySQL backup?

  - by Alex R

  I have a MySQL database which dumps to a 3.5 GB backup (mysqldump) in about 10 minutes. But reloading this backup on a standby / test server takes upwards of 12 hours. What are some settings that would maximize reloading performance? The most promising appear to be innodb_buffer_pool_size, innodb_additional_mem_pool_size, and innodb_log_buffer_size... but I'm reaching the limits of my trial-and-error approach. Which of these settings "should" be the most important? Through trial-and-error I was not able to get more than 70% CPU utilization and 63% memory utilization. I'd like both at 100% during a reload. All tables are InnoDB.

• How to get Bash shell history range

  - by Aniti

  How can I get/filter history entries in a specific range? I have a large history file and frequently use history | grep somecommand Now, my memory is pretty bad and I also want to see what else I did around the time I entered the command. For now I do this: get match, say 4992 somecommand, then I do history | grep 49[0-9][0-9] this is usually good enough, but I would much rather do it more precisely, that is see commands from 4972 to 5012, that is 20 commands before and 20 after. I am wondering if there is an easier way? I suspect, a custom script is in order, but perhaps someone else has done something similar before.

• Remove postgres from Mac - installed in /usr/local/, can I just delete files?

  - by Richard

  I want to completely uninstall postgres and start from scratch - the version I have is refusing to work with PostGIS 2.0. I have read other answers on how to do this, but none of them seem to fit the way postgres is set up on this machine. I'm not sure postgres was originally installed on this machine - it wasn't via brew or Postgres.app or the EnterpriseDB installer - but it seems to be living in /usr/local: $ which psql /usr/local/pgsql-9.1/bin/psql The postgres binary itself is in /usr/local/var/postgres/. How can I kill it forever? Can I simply go to /usr/local and do rm -rf pgsql-9.1, and the same in /usr/local/var, and make sure there are no paths in my profile file? Or is there more to it than that? From memory I think I'll need to delete the database files too somehow. Thanks for the help.

• Monitoring host and app parameters in real-time

  - by devopsdude42

  I have a bunch of VMs that I need to monitor in real-time. For all nodes I need to watch host parameters like load, network usage and free memory; and for some I need app-specific metrics too, like redis (some vars from the output of INFO command) and nginx (like requests/sec, avg. request time). Ideally I'd also like to track some parameters from the custom apps that run on these node too. These parameters should get tracked as a bunch of line charts on a dashboard. I checked out graphite and it looks suitable (although the UX and aesthetics looks like it needs some love). But setting up and maintaining graphite looks to be a pain, esp. since we don't have a full-time person just for this. Are there any alternatives? Or at least something that is simpler to setup and will scale? Reasonable paid services are also ok.

• Planning to buy a server with at least 48GB Ram, are the blades way to go?

  - by varchar1

  We're planning to host our website for the first time for ourselves. We have currently have a linode of 8 gigs and the memory is going up to 90% most of the time. So I want to move my website to my own server with huge RAM. So this will be first time to manage any physical hardware of a server. So I came across IBM's BladeCenter, found them interesting. So can I just buy the blade and run it? Or do I have to buy the chassis for sure? Also, do I need to buy an UPS? So how hard is it to setup? How about the hard drives? Can I setup them easily? Please advice.

• Slow Web Performance on two Windows 2008 R2 Terminal Servers

  - by Frank Owen

  We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load. Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January. We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

• Linux (non-transparent) per-process hugepage accounting

  - by Dan Pritts

  I've recently converted some java apps to run with linux manually-configured hugepages. I've got about 10 tomcats running on a system and I am interested in knowing how much memory each one is using. I can get summary information out of /proc/meminfo as described in Linux Huge Pages Usage Accounting. But I can't find any tools that tell me about the actual per-process hugepage usage. I poked around in /proc/pid/numa_stat and found some interesting information that led me to this grossity: function pshugepage () { HUGEPAGECOUNT=0 for num in `grep 'anon_hugepage.*dirty=' /proc/$@/numa_maps | awk '{print $6}' | sed 's/dirty=//'` ; do HUGEPAGECOUNT=$((HUGEPAGECOUNT+num)) done echo process $@ using $HUGEPAGECOUNT huge pages } The numbers it gives me are plausible, but i'm far from confident this method is correct. Environment is a quad-CPU dell, 64GB ram, RHEL6.3, oracle jdk 1.7.x (current as of 20130728)

• Does aria2 support write small files in batch?

  - by Jon

  I'm using aria2 to download 8 million jpg from flickr. Each image is about 100KB. I got a list of urls of these images in a txt file, the format is: http://farm2.staticflickr.com/1070/1151334893_5a8e7f77f4.jpg I'm wondering whether aria2 support writing small files in batch? Say write 100 image to disk when all of them are download in the memory, not just write every single file when the download is finished. Because I think writing in batch will better protect my hard disk. Or do you have other software or opensource code to recommend?

• CLI-Based monitoring tool for KVM

  - by Pinnacle

  I am developing a scheduler for running VMs on KVM. The scheduling has over-commitment of resources like memory and CPU. For this, I need a CLI-based monitoring tool that keeps me giving information about the resource usage of each VM, because it might be the case that due to over-provisioning of resources, VMs on a particular host are running very slowly depending on the benchmarks/programs each VM is running, and then I need to migrate a VM to another host and so on. I looked into libvirt-based tools like collects, MUNIN, Nagios-vert, etc.( http://libvirt.org/apps.html#monitoring ) I also looked into Ubuntu utility perf-kvm ( http://manpages.ubuntu.com/manpages/maverick/man1/perf-kvm.1.html ) I want to ask which CLI-based would be recommended by the community so that I can make a automated scheduler that takes care of the above situation.

• Staggering java linux process startup to prevent OOM

  - by ctennis

  I am running a number of java processes on a single Linux machine. From a memory and computing standpoint, everything is fine when things are static. However, periodically we use a configuration management package up upgrade the jar or war files, and restart the java process. The problem is, that is restarts them all relatively quickly, and so we get 10 or so java VMs restarting all at the same time (we use daemontools for the service stops/starts), which wreaks havoc on the machine, in terms of OOMs or just really slow. This is because it's spawning the JVM 10x at the same time. Other than trying to stagger the startups, is there a smarter way of handling this? Maybe a sysctl tuning performance parameters, or a JVM parameter?

• what does it mean for MalwareBytes to find malicious registry keys but nothing else?

  - by EndangeringSpecies

  I have a machine that is obviously infected, and when I ran MalwareBytes it told me that it found some "malicious" registry keys (surprisingly enough these contained file path to currently non-existent javascript files). But, that's it. Full scan did not uncover any malicious files, or malicious hidden processes in memory. Like, maybe the (hidden?) process that for whatever reason periodically injects keystrokes (hotkeys?) into whatever currently open window. Then on another, not obviously infected, machine it found a "malware.trace" registry key but again no files or processes etc. How does this jive with people's experience with MalwareBytes? Does it usually find registry key symptoms of an infection but nothing else? Or is it a common thing to have no infection but some malicious registry keys in place anyway?

• How to add addtional disks to a Windows 2008 KVM based Guest?

  - by taazaa

  I have a Win 2008 KVM based guest VM running on a Ubuntu 10 host. It is a raw image of 22G. I want to add a "data" drive which would show up as "D:\" drive on the guest. I first created a raw image using: qemu-img create -f raw ~/vmdisk2.img 50G Then, tried attaching it using virsh attach-disk. When that did not work, I tried editing the xml file of the VM directly. Both did not seem to work. I would greatly appreciate any help on how to do this and what the best practice is. I want to keep the base image small, so that I can clone it (hopefully) and then attach necessary storage based on the application at hand. Update: The xml of the vm before adding the second drive: <domain type='kvm'> <name>win08e-vm1</name> <uuid>183a4ba0-1c0b-0b04-ad01-aa7c3a4cb390</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>2</vcpu> <os> <type arch='x86_64' machine='pc-0.12'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='localtime'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/win08e-vm1.img'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/home/taazaa/iso/Win08ER264.iso'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:7f:a7:ae'/> <source bridge='br0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='tablet' bus='usb'/> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <video> <model type='vga' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </memballoon> </devices> </domain> Thanks!

• txt file descriptor in lsof

  - by wfaulk

  In my experience, files that have the file descriptor of txt in lsof output are the executable file itself and shared objects. The lsof man page says that it means "program text (code and data)". While debugging a problem, I found a large number of data files (specifically, ElasticSearch database index files) that lsof reported as txt. These are definitely not executable files. The process was ElasticSearch itself, which is a java process, if that helps point someone in the right direction. I want to understand how this process is opening and using these files that gets it to be reported in this way. I'm trying to understand some memory utilization, and I suspect that these open files are related to some metrics I'm seeing in some way. The system is Solaris 10 x86.

• CentOS default installation gave 60% disk space to tmpfs partition

  - by garconcn

  I installed a CentOS server which will be used for xen hypervisor. The server has two Intel(R) Xeon(R) CPU E5620 and 148G memory. The OS was installed on a 120G SSD drive. After the installation, I found that the tmpfs partition occupied about 60% of the drive. Even though I don't need much space for the OS, will there be any problem with 71G tmp partition? Thanks for any comment. [root@cloud ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 55G 1.1G 51G 3% / /dev/sda1 99M 13M 82M 14% /boot tmpfs 71G 0 71G 0% /dev/shm

• What is the maximum number of TCP connections I can have in Windows Server 2008?

  - by evilfred

  I would like to have as many connections (single connections from many different clients) as humanly possible in a server running on Windows Server 2008, in order to support a Comet-style application. The application is written in C#. The connections will not be chatty, they just need to be open (and stay open). Buying boatloads of memory and fast CPUs are not a problem. As far as I can tell, I will be limited to 65k simultaneous open connections per NIC - the maximum number of ports. Is this accurate? Or can I go beyond 65k connections / NIC somehow? It seems like there are server products for Linux at least that support hundreds of thousands of connections. How do they do this?

• Tools for analyzing performance of SQL Server/Express?

  - by Adam Crossland

  The application that I have customized and continue to support for my client is seeing dramatic performance problems in the field. Simple queries on rather small datasets take over a minute when I would expect them to complete with sub-second times. My current theory is that SQL Server Express 2005 is too limited for the rather non-trivial demands being made of it, but I am not sure how to get about gathering data that I can use to either prove my point or allow me to move on to finding another cause. Can anyone point me toward some tools that would allow me to analyze the load on this database? Information such as simultaneous connections, execution times of individual queries, memory usage, heck just any profiling data at all would be a help. Many thanks.

• What hardware factors may be considered bottlenecks on a Hyper-V virtual server during load testing?

  - by sean

  Our organization is load testing our application using virtual servers via Hyper-V to see what the user load can be using fair equipment on a single box setup. The developer group questioned the validity of the tests given the normal use of the box by the other virtual machines. IT admins answered that it is an acceptable platform to load test on because it has its own CPUs, memory and disks allocated. Is their answer mostly correct? What hardware factors may be considered bottle necks given the other virtual machines when testing our application? For example, would bus speed be a concern or network IO? The application consists of a windows service written using the 4.0 .NET Framework and SQL Server 2008 R2.

• 1tera flop cluster?

  - by Adobe

  I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: OS is supposed to be linux, application is gromacs.

• Links opened by left-click in IE8 take forever compared to middle-mouse button

  - by Bigbio2002

  When I use the middle mouse button to open a link in a new tab, it works instantly. However, if I left-click the link to open it normally, IE8 freezes for about 5 seconds before the popup window opens. I'm sick of all the slowness and the glitchiness and the memory hogging, and I just want it to work as well as all the other browsers out there. Anybody else experiencing this and have any tips? Note: It's not the Java SSV helper or the Skype addon (because I have those disabled). I'm looking for some advanced solutions that I can try. (God, I hate IE8, but I'm a loyal Microsoft follower so I refuse to switch to Firefox. )

• Zabbix - Some of the monitored items dont get refreshd. how to find the reason?

  - by Niro

  I'm experiencing a strange issue with Zabbix monitoring a MySQL server. Most of the data from the server such as MySQL queries per second and MySQL uptime , Buffers memory etc. update nicely while some data like CPU iowait time (avg1) , Host local time ,MySQL number of threads and other items which were monitored in the past has last check time of about a week ago. I can't find any logic in this, for example Mysql number of threads and Mysql queries per second are obtained in a similar way so it does not make sense one of them is monitored and one is not. Please help- how can I fix this?

• Linux says a kernel module has an unknown symbol, but another loaded module provides it.

  - by raldi

  I'm trying to install a driver for a USB DAQ box, which annoyingly, I have to compile myself. I believe I've succeeded -- I have two .ko files: -rw-r--r-- 1 root root 45271 2010-03-18 21:24 advdrv_core.ko -rw-r--r-- 1 root root 24312 2010-03-18 21:24 usb4761.ko I was able to run insmod on the first without incident, but when I try on the second, I get a flood of messages: kernel: [686782.106547] usb4761: no symbol version for adv_process_info_check_event kernel: [686782.106555] usb4761: Unknown symbol adv_process_info_check_event kernel: [686782.106691] usb4761: no symbol version for advdrv_unregister_driver kernel: [686782.106695] usb4761: Unknown symbol advdrv_unregister_driver However, advdrv_core.ko provides these symbols.
