• Rsyslogd not listening on port

  - by amorfis

  I installed rsyslogd on ubuntu server, started it and everything looks fine, but the port the server should listen on is not opened. ubuntu@node7:~$ sudo service rsyslog restart rsyslog stop/waiting rsyslog start/running, process 14114 Netstat shows it is not listening: ubuntu@node7:~$ netstat -tlan Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 320 172.22.0.17:22 10.8.8.38:61335 ESTABLISHED tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 :::2776 :::* LISTEN tcp6 0 0 :::2777 :::* LISTEN tcp6 0 0 172.22.0.17:2777 172.22.0.11:56554 ESTABLISHED tcp6 0 0 172.22.0.17:2776 172.22.0.11:39780 ESTABLISHED This is how /etc/rsyslog.conf looks like (most comments omitted): ubuntu@node7:~$ cat /etc/rsyslog.conf ################# #### MODULES #### ################# $ModLoad imuxsock # provides support for local system logging $ModLoad imklog # provides kernel logging support (previously done by rklogd) $ModLoad imtcp $InputTCPServerRun 514 ########################### #### GLOBAL DIRECTIVES #### ########################### $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $RepeatedMsgReduction on $WorkDirectory /var/spool/rsyslog $FileOwner syslog $FileGroup adm $FileCreateMode 0640 $DirCreateMode 0755 $Umask 0022 $PrivDropToUser syslog $PrivDropToGroup adm $IncludeConfig /etc/rsyslog.d/*.conf In /etc/rsyslog.d/35-server-per-host.conf I have following lines, and I suspect this can be the cause.

UPDATE: I commented out suspected line, but still it's not listening on port 514

• How long will a USB key with an OS installed on it last?

  - by Xananax

  I've heard numerous times that installing an OS on a USB key is a bad thing to do, as USBs typically have a certain number of writes before dying, and installing an OS on it will wear it out (unless it's used sporadically for rescue purposes). Nonetheless, I am very tempted to install some flavour of Linux (Ubuntu or Arch, I haven't decided yet) on a small, transportable, USB Key. My problem is, although you read a lot that it's "bad", you are never told how bad. How long would it last (provided, say, a pc that is 24/7 on)? A month? A year? Five years? Is there recipes to make it last longer? Is there any reason beside weariness that should prevent me from attempting this? I mean, if it can be calculated, then I could theoretically shield myself by doing regular backups on another key when the deadline gets close (for example). Notes I am not talking of using a USB as a live CD, but actually installing the OS on it.) When I say "USB Key", I refer to the little USBs with a flash memory, not an external USB hard drive. For the curious, my reason is that I work in a lot of different places, on different PCs, and I have a very customized session, with my own WM, my own key bindings, my own scripts, , a selection of plugins for firefox and chrome, etc, and currently I am synchronizing all this through a mix of dropbox, git, and transporting files on USBs, and and it's becoming a chore. It would be much simpler for me to just plug the USB and mount the hard disk of the PC I am using and use it's processing power without actually needing to install any OS on it.

• Exchange 2007 OWA returns blank page with url xxxxx&reason=0

  - by Dayton Brown

  Hi All: I've just run into an issue with my exchange OWA. It returns a blank page with the url string https://www.xxxxxxxx/&reason=0. Nothing in the logs gives me any good reasons. Here's what I've done so far; 1) reinstall Exchange roll-up 7. 2) recreate virtual directories. 3) reboot. (this was mostly a shot in the dark, but what the hell) Exchange via rpc/https is still working great. Anyone run into this before?

• APACHE - PHP - Bounce emails

  - by user1179459

  I want to improve our mail server lists by handling all the bounces we get in our websites. I have a website which has over 8000+ users and another website which as over 1500+ users, they are emailed various notifications every second, ie. job alerts, email alerts, I am using POP connections with EXIM on APACHE server, most scripts are based on PHP language generates email on the fly. Problems i have But some users has registered long time ago and now quite few has bounce email address Some users register with dummy emails like [email protected] which never existed but a valid email address, any chance of stopping this without asking them login to the email account and clicking links which dont work most times.. (too annoying to the end user) Server is sending unnecessary emails can be avoided if i know they dont exists ? Solutions i need to have Is there a way i can download the bounce email list somewhere (WHM/Cpanel), i know exim mail has it but its not readable (i need a file like CSV or something similar to scan them over and write a php script to delete the users from the database ?) I need to know if there is any function in the PHP that can check the existence of the email address on the fly ? so that i can set the email send function in the mailer class to check before it sends out. On the server will bouncing emails are going to eatup lots of server resources ? like memory/cpu on processing them ? or are they are minimal where we dont have to worry about this at all ? May be a opensoruce or linux software to capture them and view them in a report basis and cleaning them up ? I am not a linux expert or server admin but i do lot of PHP coding, so please be descriptive of the solutions specially if they are linux commands Thank you!

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• Strange IIS hits originating from Trend Micro

  - by TesterTurnedDeveloper

  I'm trying to trace thru an error on a extranet site I maintain. I've had a look thru the logs, and I'm seeing hits originate from these IP addresses: 216.104.15.130 216.104.15.138 216.104.15.142 216.104.15.13 150.70.84.49 150.70.84.44 Network-tools.com gives 'TREND MICRO INCORPORATED' as the owner of all these IPs. The hits fail as they aren't sending any cookies (therefore aren't considered logged in). The hits are to pages containing URLs that only the logged in user would see, i.e. ImageEdit.aspx?ImageId=467424. I.e. the server isn't guessing these URLs, someone would have to log into the site to know these URLs exist. Theory: the Trend Antivirus client grabs URLs and sends them to the server for 'extra processing'? Googling around gives me this: http://www.forumpostersunion.com/showthread.php?p=51272 - where people are reporting comment spam from these addresses. The articles says their servers have been hacked (a few months ago, presumably fixed now?). A hacked server wouldn't explain how the URLs have been plucked off the user's PCs. Has anyone seen this before? Anything nefarious going on here?

• Slow boot for OS and external devices

  - by Derek Van Cuyk

  I have been having this problem intermittently but as of yesterday, it has become more consistent. It originally started when I rebooted my PC at home and the OS (Windows 8) sat in a loop appearing to do nothing while loading. I figured since this was a new installation, that something may have just become corrupted and I decided to reinstall. So I tried to boot off of the thumb drive which had the installation iso and encountered pretty much the same issue. Same with the DVD drive. So, I rebooted once again and left it to load the entire night just to see if it ever would and sure enough this morning, Windows had finally loaded. Authentication had the same roblem albeit not quite as long (took about 5 minutes to authenticate). However, once I was in, everything appeared to be working fine and as quick as normal with the exception of when I tried to scan the C drive for any errors, which ran unbearably slow (45 minutes and before I left for work and was not finished scanning a 64GB SSD drive). I mention that I have had this issue but never when loading the OS. Before it occurred when trying to install windows 7 from a different DVD drive than the one I have now. It took me about 3 hours to do it since I had to wait sometimes 30+ min for each step to finish processing. Does anyone have an idea as to what can cause this? I am assuming it is the motherboard since it is responsible for communication with all the devices I'm having issues with but I cannot find anyone else who has had a problem like this and don't want to drop more money on a MB if it isn't the problem. Hardware: Motherboard: Asus M4A78T-E Socket AM3/ AMD 790GX/ Hybrid CrossFireX Hard Drive: Kingston SSDNow V+180 64GB Micro SATA II 3GB/S 1.8 Inch Solid State Drive SVP180S2/64G Optical Drive: Samsung Blu-Ray Combo Internal 12XReadable and DVD-Writable Drive with Lightscribe SH-B123L/BSBP Thanks, Derek

• Hosting WCF over Internet

  - by karthik

  I am pretty new to exposing the WCF services hosted on IIS over internet. I will be deploying a WCF service over IIS(6 or 7) and would like to expose this service over the internet. This will be hosted in a corporate network having firewall, I want this service to be accessible over the internet(should be able to pass through the firewall) I did some research on this and some of the pointers I got: 1. I could use wsHTTPBinding or nettcpbinding (the client is intended to be .net client). Which of the bindings is preferable. 2. To overcome the corporate I came across DMZ server, what is the purpose of this and do I really need to use this). 3. I will be passing some files between the client and server, and the client needs to know the progress of the processing on server and the end result. I know this is a very broad question to ask, but could anyone give me pointers where I could start on this and what approach to take for this problem. Any help will be appreciated. Thanks Karthik

• Starting my own server - basic recommendations and questions [closed]

  - by Ilia Rostovtsev

  Possible Duplicate: Can you help me with my capacity planning? I'm planning to start my own high-performance server and then use collocation services for keeping it up and running. I'm planning to USE it for processing videos and keeping big video site up! (using FFMpeg, MENcoder and etc.) I just need recommendations on whether listed hardware is good enough and will work together well and fast enough. Do I need anything else (missed something). I remember about CPU coolers though! ;) I'm planning to use SSD drives so please tell me if it's going to work just as regular HDDs (but much faster)? Are they going to be used as RAID (is this possible for SSDs)? Here is what I would like to get: Intel ® Server System SR1600URHSR (Urbanna) or Intel® Server System SR1695WBAC 2 x Intel Xeon X5650 4 x 16Gb DDR-III 1333MHz Kingston ECC Reg (KVR13R9D4/16) 3 x (or maybe 4x) 480Gb SSD Intel 520 Series (SSDSC2CW480A3K5) Which server system would be better? Is listed hardware new/good enough and worth buying it at the moment? Should I probably take a look at something slightly more expensive but more up to date and powerful, may be? After all as software I would like to use CentOS 6 64 bit + WHM/CPanel? Any other suggestions on maybe cheaper and same/more powerful server management system but WHM? What most important points to keep in mind when starting/maintaining your own server?

• How to manage processes-to-CPU cores affinities ?

  - by Philippe

  I use a distributed user-space filesystem (GlusterFS) and I would like to be sure GlusterFS processes will always have the computing power they need. Each execution node of my grid have 2 CPU, with 4 cores per CPU and 2 threads per core (16 "processors" are seen by Linux). My goal is to guarantee that GlusterFS processes have enough processing power to be reliable, responsive and fast. (There is no marketing here, just the dreams of a sysadmin ;-) I consider two main points : GlusterFS processes I/O for data access (on local disks, or remote disks) I thought about binding the Linux Kernel and GlusterFS instances on a specific "processor". I would like to be sure that : No grid job will impact the kernel and the GlusterFS instances Researchers jobs won't be affected by system processes (I'd like to reserve a pool of cores to job execution and be sure that no system process will use these CPUs) But what about I/O ? As we handle a huge amount of data (several terabytes), we'll have a lot of interuptions. How can I distribute these operations on my processors ? What are the "best practices" ? Thanks for your comments!

• Performance: Nginx SSL slowness or just SSL slowness in general?

  - by Mauvis Ledford

  I have an Amazon Web Services setup with an Apache instance behind Nginx with Nginx handling SSL and serving everything but the .php pages. In my ApacheBench tests I'm seeing this for my most expensive API call (which cache via Memcached): 100 concurrent calls to API call (http): 115ms (median) 260ms (max) 100 concurrent calls to API call (https): 6.1s (median) 11.9s (max) I've done a bit of research, disabled the most expensive SSL ciphers and enabled SSL caching (I know it doesn't help in this particular test.) Can you tell me why my SSL is taking so long? I've set up a massive EC2 server with 8CPUs and even applying consistent load to it only brings it up to 50% total CPU. I have 8 Nginx workers set and a bunch of Apache. Currently this whole setup is on one EC2 box but I plan to split it up and load balance it. There have been a few questions on this topic but none of those answers (disable expensive ciphers, cache ssl, seem to do anything.)

• XP Pro freezes on welcome screen

  - by Peter B

  I have a problem that sounds much the same as http://superuser.com/questions/83101/how-to-diagnose-a-freeze-on-startup-in-windows-xp About every 2nd or 3rd boot, XP-Pro freezes on the Welcome page (the one showing the user name icons). The mouse moves the cursor OK, but clicking on an icon does nothing, and neither does any keystroke. If you press too many keys there is a beep and after that the mouse won't move the cursor anymore. The work-around is always to reboot into Safe mode and request a CHKDSK /R After this, the next boot is fine. There are no related entries in the Event log when the problem occurs. The only two entries are: "Microsoft (R) Windows (R) 5.01. 2600 Service Pack 3 Multiprocessor Free." "The Event log service was started." Update 1: Many thanks for that but I found no problems with any diagnostics I have run. But, I have managed to locate, and code round, the source of the problem - which is with whatever processing goes on behind the XP Welcome (as opposed to "classic") login screen. Unfortunately, having classic login means you don't get the useful Fast User Switching (FUS) login/switch mode. So, to retain this, my fix is: Add a Windows shutdown script (using gpedit.msc) to force "classic" mode for the first logon after next XP startup, by running: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v LogonType /t REG_DWORD /d 0 /f Add a Scheduled Task to run at User Logon that enables Welcome screen (and hence FUS) by running the same command with 1 instead of 0 after the /d flag. The task is run as a privileged user (who can run "reg add").

• How to change libcurl SSL backend from gnutls to openssl on Ubuntu server

  - by Jayesh

  I am getting gnutls specific errors in my Tornado webserver while processing Google OpenID SSL responses. One of the suggestions I got from Tornado mailing list is to try OpenSSL backend instead of gnutls. But it doesn't seem to be straightforward on Ubuntu server (11.10). On Ubuntu server, gnutls is provided by libcurl3-gnutls package and openssl curl support is provided by libcurl4-openssl-dev package. (I don't know why the later is named 4 and dev, but I couldn't find any other openssl+curl package in apt-cache search). I had libcurl3-gnutls installed by default, but not libcurl4-openssl-dev. So I installed the later and restarted Torando instances. But that didn't seem to work. I still got same gnutls errors. I found old discussions on curl mailing lists regarding the problems of supporting different SSL backends to libcurl, but didn't find exactly how is it done today. So far my guess is openssl is built into libcurl and gnutls is provided through separate package (that will explain why there is no libcurl3-openssl). But how do I make libcurl to pick up openssl backend and not gnutls? Is there some option in libcurl/pycurl API to do this? I tried uninstalling libcurl3-gnutls, but apt-get prompted that it will also remove python-pycurl along with it. So that won't do.

• ADFS Relying Party

  - by user49607

  I'm trying to set up an Active Directory Federation Service Relying Party and I get the following error. I've tried modifying the page to allow <pages validateRequest="false"> to web.config and it doesn't make a difference. Can someone help me out? Server Error in '/test' Application. A potentially dangerous Request.Form value was detected from the client (wresult="<t:RequestSecurityTo..."). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section.

• IIS 7.0 - responses throttled to 500ms blocks?

  - by Julia Hayward

  Scenario: ASP.NET MVC wep app sitting on my local machine (Vista Ultimate, IIS 7.0), nothing going on except one user (me) logged in and viewing an index page. The page includes 9 dynamic images drawn from the underlying DB and returned from a controller action. I have got the actual processing time for these images down to 15ms each. Turn on Firebug and watch the page load. What I see is 9 requests for images firing off together – no surprise – but four come back to me almost immediately; two more after 0.5s; another after 1s; then at 1.5s and 2s. Logging on the server side suggests the individual responses are still only taking 15ms. So it appears IIS is queueing things up into 500ms chunks. (Repeating the experiment produces different results, but each time the images return in similar blocks – you might get three in the first group, then three at 0.5s, two at 1s etc, for example – and it’s always at 500ms intervals, not anything else.) It’s also repeatable cross-browser, and it’s not repeatable with other forms of content. I haven't found any particular mention of this problem out there, so I'm sort of assuming it's not an IIS bug, so is it: i) IIS on desktop OSs deliberately does it, to make you use server OSs in production? ii) There is some magical setting that has eluded me for as long as I’ve known IIS? iii) Something peculiar to MVC or SQL Server 2008? or something else?

• Windows, why 8 GB of RAM feel like a few MB?

  - by Desmond Hume

  I'm on Windows 7 x64 with 4-core Intel i7 and 8 GB of RAM, but lately it feels like my computer's "RAM" is located solely on the hard drive. Here is what the task manager shows: The total amount of memory used by the processes in the list is just about 1 GB. And what is happening on my computer for a few days now is that one program (Cataloger.exe) is continually processing large quantities of (rather big) files, repeatedly opening and reading them for the purposes of cataloging. But it doesn't grow too much in memory and stays about that size, about 90 MB. However, the amount of data it processes in, say, 30 minutes can be measured in gigabytes. So my guess was that Windows file caching has something to do with it. And after some research on the topic, I came across this program, called RamMap, that displays detailed info on a computer's RAM. Here is the screenshot: So to me it looks like Windows keeps in RAM huge amounts of data that is no longer needed, redirecting any RAM allocation requests to the pagefile on the hard drive. Even when I close Cataloger.exe, the RamMap reports the size of the mapped file as about the same for a long time on. And it's not just this particular program. Earlier I noticed that similar slowdown occurred after some massive file operations with other programs. So it's really not an exception. Whatever it is, it slows down the computer by like 50 times. Opening a new tab in Chrome takes 20-30 seconds, opening a new program can take up to a minute. Due to the slowdown, some programs even crash. So what do you think, is the problem hiding in file caching or somewhere else? How do I solve it?

• What can I do to prevent system power downs?

  - by Joe King

  Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

• avconv gets killed if mkv has subtitles

  - by Lukas Knuth

  What I'm trying to do is to take a movie (in an Matroska container), convert all audio tracks to AC3 and don't touch anything else. I'm using this line: avconv -i infile.mkv -map 0 -vcodec copy -scodec copy -acodec ac3 -ab 256k outfile.mkv This works fine, except when there are subtitles embedded. Then, after some time processing with no progress, avconv just "dies" (output shortened, these seem to be the interesting parts): [matroska,webm @ 0xf867a0] max_analyze_duration reached [matroska,webm @ 0xf867a0] Estimating duration from bitrate, this may be inaccurate ...

I'd like to just copy the subtitles over, not touch them at all. If that won't work, they can be completely dropped.

• How to find process that's using 100% of CPU

  - by Gabriel

  As i'm looking at htop and top i see that my processor usage is 100% allways. But i can not see any process that is using that much CPU. Htop shows me only 1-2 processes that use around 5% cpu time. Is there a way to find the processes that use that much cpu time? Here is the output of ps -eo pcpu,pid,user,args | sort -r -k1 | less %CPU PID USER COMMAND 0.8 20413 root jsvc.exec -user tomcat -cp ./bootstrap.jar -Djava.endorsed.dirs=../common/endorsed -outfile ../logs/catalina.out -errfile ../logs/catalina.err -verbose org.apache.catalina.startup.Bootstrap -security 0.3 631 mysql /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/mysql.pid --skip-external-locking 0.2 3380 root /usr/local/apache/bin/httpd -k restart -DSSL 0.2 24698 root tailwatchd 0.2 22472 root /usr/local/jdk/bin/java -Djava.util.logging.config.file=/usr/local/jakarta/tomcat/conf/logging.properties -Dfile.encoding=UTF8 -XX:MaxPermSize=128m -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/jakarta/tomcat/common/endorsed -classpath /usr/local/jakarta/tomcat/bin/bootstrap.jar -Dcatalina.base=/usr/local/jakarta/tomcat -Dcatalina.home=/usr/local/jakarta/tomcat -Djava.io.tmpdir=/usr/local/jakarta/tomcat/temp org.apache.catalina.startup.Bootstrap start 0.1 32095 root cpanellogd - processing bandwidth 0.0 9733 root sleep 1m

• recursive grep started at / hangs

  - by Martin

  I have used following grep search pattern on multiple platforms: grep -r -I -D skip 'string_to_match' / For example on FreeBSD 8.0, FreeBSD 6.4 and Debian 6.0(squeeze). Command does a recursive search starting from root directory, assumes that binary files do not have the 'string_to_match' and skips devices, sockets and named pipes. FreeBSD 8.0 and FreeBSD 6.4 use GNU grep version 2.5.1 and Debian 6.0 uses GNU grep version 2.6.3. On FreeBSD 6.4, last information printed to stderr was "grep: /dev/cuad0: Device busy". After this grep just idles as according to "top -m io -o total" the I/O usage of grep is nonexistent. Same behavior is true under FreeBSD 8.0, but last information sent to stderr is "grep: /tmp/.wine-0: Permission denied" on my installation. In case of Debian, last output to stderr is "grep: /proc/sysrq-trigger: Input/output error". If I check the I/O usage of grep process under Debian, it is following: root@Debian:~# iotop -bp 22439 Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / ^Croot@Debian:~# What might cause this? Is there a way to view which file grep is currently processing in case lsof is not present? I'm able to use lsof under Debian and looks like the problematic file name there is "0xc6b2c230 file struct, ty=0, op=0xc0d34120". I'm not sure what this is.. I'm not able to use lsof or fstat under FreeBSD. PS: I know I could use find utility, but this is not the question.

• HyperV - low CPU usage

  - by Klark

  I am very new to HyperV and virtual machine philosophy in general, so please expect more or less nooby questions :) I have a server that is only used as a host for virtual machines. OS is windows server 2008 R2 and it is running on 16 CPU and 48 GBs of RAM. On aforementioned server there are 8 VMs, each having 4 CPUs and 4 GBs of RAM. On those VMs we are running some CPU intensive tasks. Each machine has nearly 100% cpu usage. After I noticed slow performance I went to the host machine and started playing with process explorer. It turned out that cpu usage is very low. Also I/O is very low, and of course, memory consumption is high, which is expected. Of course, I don't expect that those 4 virtual cores dedicated to a VM work as fast as real, hardware 4 cores, but still I expected a higher consumption of real hardware. Is this sort of behaviour normal? I see that the most of CPU usage on host machine are marked as interrupts (which I guess is normal) and all those interrupts are passed to only one core (which is strange). Are there out of box optimization that I could perform to finally use all that processing power that is under the hood. My knowledge of virtualization technology is near to embarrassing, so I would be grateful for any links that could enlightened me :) Thanks.
