• CPU & Memory Usage Log & Performance

  - by wittythotha

  I want to have an idea of the amount of CPU and memory that is being used. I have a website hosted using IIS, and have clients connecting to it. I want to find out the amount of load that the CPU, RAM and the network has when multiple clients connect. I tried out using tools like Fiddler, the inbuilt Resource Manager, and also some other applications I found on the internet. I just want to keep track of all these data in a file, so I can plot out a graph and find out how the CPU, etc. is performing. I read a few other posts, but didn't find anything that solves the problem. Is there good CPU / Memory Logging tool available, just to plot a graph of the usage, etc.? EDIT : I want to know of some tool that can save the performance details in a log file, so that I can use it to plot a graph, etc.

• Thunderbird: mails not displayed while everything worked a few minutes ago

  - by roland

  Hi all, I upgraded my Kaspersky and I closed everything before launching the upgrade process. Everything went well, but when I launched my Thunderbird, no mail and content were displayed. Everything is blank. Strangely my accounts are detected when expanding Tools/Account Settings. I completely closed Kaspersky and launched Thunderbird again, but it fixed nothing :( It is as if closing Thunderbird has damaged a core file. Any idea how to fix it? Thanks. Roland

• check_mk IPMI PCM sensor reading randomly fails

  - by Julian Kessel

  I use check_mk_agent for monitoring a server with IPMI and the freeipmi-tools installed. As far as I can see, the monitoring randomly detects no value returned by the IPMI Sensor "Temperature_PCH_Temp". That's a problem since it results in a CRITICAL state triggering a notification. The interruption lasts only over one check, the following is always OK. The temperature is in no edge area and neither the readings before the fail nor after show a Temp that is tending to overrun a treshold. Has someone an idea on what could be the reason for this behaviour and how prevent it?

• Como instalar Windows (x86/x64) sobre Linux (Ubuntu)

  - by yorrany

After I was forced to reverse the process, but could not find tools or explanations of how to do it.

• Registering OCX on 64-bit Windows 7

  - by Jay

  I want to use MSCOMM control in my MS Excel 2010 VBA. The control shall appear in Tools-> Additional Controls dialog box in VBE of MS Excel 2010. I am trying to register MSCOMM32.OCX on my 64-bit Windows 7 machine. However, as I try to register it using regsvr32 as shown in the command window below, I am getting shown error popup. What am I missing here? Why is this component not getting registered? Or this is not the correct way to include MSCOMM control in MS Excel VBA? I have read following: Registering OCX file manually http://social.msdn.microsoft.com/Forums/en/vbgeneral/thread/1f00d6cc-00a9-4ca0-9698-535e2487af31 But to no avail.

• How to know the root device size of some public AMI?

  - by red23jordan

  Since I do not want to pay money for my testing, the free limit size is 10G. I can know the root device root for some default AMI such as Amazon Linux AMI 2012.03 The Amazon Linux AMI 2012.03 is an EBS-backed, PV-GRUB image. It includes Linux 3.2, AWS tools, and repository access to multiple versions of MySQL, PostgreSQL, Python, Ruby, and Tomcat. Root Device Size: 8 GB And the last row displayed 8GB. However, if I find AMI in Community Page, it does not show the root device size. Can anyone know how to use the instance such as centOS that is not provided by default but it is under 10GB so that I can still free use?

• Fix bad blocks on Mac hard disk

  - by Andrew Vit

  I have a hard disk that I scanned with TechTool and it reports one bad block. As far as I can tell, TechTool only scans and reports a failure. It doesn't fix anything. Back in the day, Norton Disk Doctor did the job of scanning and flagging (remapping) bad blocks on the Mac. Today we have various tools for fixing up HFS+ directory errors (Disk Utility, fsck, DiskWarrior, TechTool), but I don't know of any tool that will do a surface scan and fix the bad blocks too. What software is available for this? If I know the address of the bad block, is there a low-level terminal utility for marking it?

• Is there a way to create a copy-on-write copy of a directory?

  - by BCS

  I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.) What I'm looking for could be done by creating a new directory structure and populating it with hard links from the origonal. However this only works if all the tools you use delete and recreate files rather than edit them in place. Is there a way to have the file system do copy-on-write for a file? Note: I'm aware that many FSs use COW at a block level (all updates are done via writes to new blocks) but this is not what I want.

• Help changing MAC address in Windows 7 [closed]

  - by Niphoet

  Possible Duplicate: Change MAC Address I need to change the MAC address of my wireless adapter in Windows 7 (Ultimate RTM). I used to do this in XP both directly in the registry editor and with a .REG file I wrote. I have used each of these methods in Windows 7, as well as a few tools I found that are supposed to do this. Every time I change it, I disable and re-enable the network adapter in control panel, but upon running ipconfig /all it still shows my old MAC address. Any help? By the way, I do have Administrative Rights and UAC turned off.

• AWS EC2 can't execute user-data script

  - by Bloodnut

  I'm pretty new to AWS and EC2 but I want to run instances with a user script after it's booted from another instance. I have installed ec2 tools and ran the command as it's explained in various examples like here http://www.turnkeylinux.org/blog/ec2-userdata and Eric Hammond's tutorials. however when I actually use the command: "ec2-run-instances --key my-key --user-data-file myscript my-ami" it only runs the new instance but doesn't execute the script myscript contains: #!/bin/bash echo "hello" ~/output.txt I'm running ubuntu server 12.04 AMIs. the target AMIs are duplicates of the initiating instance. if I run curl http:// 169.254.169.254/latest/user-data the imported script is there.

• KVM CLI install for CentOS 6.3 defaults to Minimal Install

  - by i.h4d35

  So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

• Need help setting up OpenLDAP on OSX Mountain Lion

  - by rjcarr

  I'm trying to get OpenLDAP manually configured on OSX Mountain Lion. I'd prefer to do it manually instead of installing OSX server, but if that's the only option (i.e., OpenLDAP on OSX isn't meant to be used without server) then I'll just install it. I've seen guides that mostly just say to change the password in slapd.conf and then start the server and it should work. However, whenever I try to do anything with the client it tells me this: ldap_bind: Invalid credentials (49) I've tried encrypting the password as well as leaving it plain it doesn't seem to matter. The version is 2.4.28 and I've read as of 2.4 OpenLDAP uses slapd.d directories, but that doesn't seem to be the case in OSX. There was mention of an 'olcRootPW' I should use (instead of 'rootpw' in slapd.conf), but I only found that in a file named slapd.ldif. So ... I'm really confused. Has anyone got OpenLDAP working on OSX Moutain Lion without the server tools?

• Linux Transparent Bridge for Network

  - by Blackninja543

  I am attempting to set up a semi-transparent bridge. I say semi because I want it to act as a transparent tap for all traffic moving through both sides of the bridge. What I also want is to have the "green zone" accessible to a web interface for the bridge that will display all results of the IDS and other network monitoring tools. My example would be as such: eth0 <--> bridge(br0) <--> eth1 The entire network would be on the same subset however anything coming from eth0 to eth1 would be accepted. The only time anything would be drop is if the eth0 attempted to access br0. If someone attempts to access the web interface on br0 through eth1 it will succeed. My biggest problem I feel is if I attempt to block anything from eth0 to br0 this will drop the bridge all together.

• Turning a log file into a sort of circular buffer

  - by pachanga

  Folks, is there a *nix solution which would make the log file act as a circular buffer? For example, I'd like log files to store maximum 1Gb of data and discard the older entries once the limit is reached. Is it possible at all? I believe in order to achieve that a log file should be turned into some sort of special device... P.S. I'm aware of misc logrotating tools but this is not what I need. Logrotating requires lots of IO, happens usually once a day while I need a "runtime" solution.

• IE "About:Tab" page hijacked

  - by tcv

  Hey folks, Client o' mine, running Windows 7 64-bit, installed Kiwee Toolbar and then uninstalled it. The software is pretty much gone except for one last thing: The About:Tab IE page redirects to a Kiwee search page. I have temporarily disabled the "New Tab" page via Internet Explorer's options, but it annoys me. I have scanned with multiple tools. Spyware Doctor purports to removed it, but they want money to remove it. I would buy it -if- I could be certain it would fix the problem. I've also searched the registry and the filesystem for instances of the program, plus I've removed Kiwee manually via the many manual uninstalls out there. IE's AboutURLs registry entry still points to res://ieframe.dll/tabswelcome.htm and if I enter that URL into IE, the correct New Tab page comes up. Any help appreciated.

  Hello everyone I have a SD memory card which is of local manufacturer it allows to read & copy from it but not write as it is now write-protected so i want to format that card but could not.

• Linux command to concatenate audio files and output them to ogg

  - by hasen j

  What command-line tools do I need in order to concatenate several audio files and output them as one ogg (and/or mp3)? If you can provide the complete command to concatenate and output to ogg, that would be awesome. Edit: Input files (in my case, currently) are in wma format, but ideally it should be flexible enough to support a wide range of popular formats. Edit2: Just to clarify, I don't want to merge all wmas in a certain directory, I just want to concatenate 2 or 3 files into one. Thanks for the proposed solutions, but they all seem to require creating temporary files, if possible at all, I'd like to avoid that.

• Creating an interactive "movie" from a Microsoft PowerPoint 2003 presentation (.ppt file) containing animation

  - by Andrew

  I have created a Microsoft PowerPoint 2003 presentation (a .ppt file) on Windows XP that contains a lot of animation, using PowerPoint's Custom Animation tools. I would like to share this presentation -- animations and all -- with a colleague who has a Mac computer and does not have PowerPoint or Keynote. Is it possible to make a "movie" from my .ppt file that contains a lot of animation? I recall that another colleague once made me a QuickTime "movie" from a PowerPoint file, I think (although I do not remember whether he made it using Windows or Mac). On this "movie," clicking advanced the animation/slide, just as clicking would do in an actual PowerPoint presentation. In that sense, it was not really strictly a movie, since I could interact with it by clicking. Do you know how to make such an interactive "movie" from a PowerPoint 2003 presentation (a .ppt file)? Thank you for your time!

• finding the user of iis apppool \ defaultapppool

  - by LosManos

  My IIS apppool user is trying to create a folder but fails. How do I find out which User it is? Let's say I don't know much about IIS7 but need to trace whatever is happening through tools. Place of crime is WinSrv2008 with IIS7. So I fire up Sysinternals/ProcessMonitor to find out what is happening. I find Access denied on a folder just as I suspected. But which user? I add the User column to the output and it says IIS Apppool\Defaultapppool in capitals. Well... that isn't a user is it? If I go to IIS and its Apppools and Advanced settings and Process model and Identity I can see clues about which user it is but that is only because I know IIS. What if it had been Apache or LightHttpd or whatever? How do I see the user to give the appropriate rights to?

• Questions about adding space to an Amazon EC2 Instance

  - by Misha

  I have an Amazon EC2 instance that is running a simple LAMP stack with Amazon's flavor of linux. I want to stop it and add more disk space. We will need more than our current 8 gigabytes. I was wondering: 1) When I stop my instance what will be lost? Will the content of /var/www be lost? What does this mean? I am sure my instance isn't a spot instance. 1.5) What is an ephemeral disk? Is my instance completely ephemeral? Are parts of it ephemeral? When I press "stop", probably, not everything is cleared. So what is cleared? 2) Amazon has tools in the Management Console to facilitate enlarging an instance? 3) Will I have to re-partition the instance? Can an instance expand the partition it is running on?

• Samsung 830 very slow benchmark numbers

  - by alekop

  I just bought a new SSD, and installed a fresh copy of Windows on it. I didn't see any noticeable difference in boot times, app start-up times, so I decided to benchmark it. Asus P7P55D-E Intel i5-760 Samsung 830 256GB SATA III Windows 7 Ultimate 64-bit The Windows experience index gave the drive a 7.3 rating, but real-world performance is not particularly impressive. Any ideas why the numbers are so low? UPDATE: It turns out that SATA III support is turned off by default on the P7P55D motherboard. After enabling it in BIOS (Tools - Level Up), the scores went up: Read Write Seq 325 183 4K 16 49 IOPS 32K 28K It's an improvement, but still far below what they should be for this drive.

• Getting HAPROXY to redirect http to https in users browser session

  - by Jon

  We are currently using a Internet cloud provider to host our SaaS platform. The platform consists of a Firewall - Cloud Provider SLB - - Apache Web Server - HAPROXY SLB - Liferay Platform We have had to use HAPROXY because of an issue with the cloud providers SLB that meant we were unable to use it for load balancing the Liferay platform applications. I have implemented HAPROXY in our secure tier and that seems to do the trick of load balancing the requests quite adequately. However during testing we encountered a functional issue whereby selecting a sub-menu from the web portal resulted in the application hanging, using an http analyser we saw that the request being passed back to the users browser was in http, from discussing this with the software vendor it transpires that the Liferay application has some hard-coded http links, and that other customers have worked around this by using physical NLB's such as F5 and redirecting the http traffic to https. The entry in the HAPROXY logs reads: haproxy[2717]: haproxy[2717]: <Apache Web Agent>:37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" :37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" The corresponding HTTP browser entry shows: http://<FQDN of ServiceDesk>/servicedesk/controller?docommand=renderradform&!key=esd_org019_frm_contact_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365665987887&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&sso_token=3NxsXYORMPp32SwL8ftVUCMH2QdWLH82&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fapplication-setup&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-10-26%2019:00:25.08 From reading through the forums and other sites it looks like we should be use to use HAPROXY to redirect the traffic to https, but try as I might I cant get it to work.

• Using DD for disk cloning

  - by roe

  There's been a number of questions regarding disk cloning tools (yes, I did search for it) :) and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all run of the mill bootable linux distributions. To my question, what is the best way to use dd for cloning a disk. I don't have much time to go around, and no test-hardware to play with, so I need to be prepared, and it's pretty much a one-shoot chance to get it done. I did a quick google search, and the first result was an apparent failed attempt. Is there anything I need to do after using dd, i.e. is there anything that CAN'T be read using dd? Thanks!
