• ubuntu VM not detecting CDdrives

  - by Mirage

  Ihave insatlled ubuntu 10.4 on my compuer with 6 cd drives. Now initiallyi had window server 2008 and i had to install marvel raid sata controller and then my window detected all 6 drives. Now ubuntu is detecting only 3 drives and i have not found marvell drivers for ubuntu bt i have drives for window 2008. Now my question is if i have vrtual machine inside ubuntu using vmware workstation and i install that driver. then can VM dtect thse 6 drives or host has to detect those drives first to make VMs use that Ubuntu shows this thing from terminal *-cdrom:0 description: DVD-RAM writer product: DVDRAM GSA-H10N vendor: HL-DT-ST physical id: 0.0.0 bus info: scsi@0:0.0.0 logical name: /dev/cdrom2 logical name: /dev/cdrw2 logical name: /dev/dvd2 logical name: /dev/dvdrw2 logical name: /dev/scd0 logical name: /dev/sr0 version: JL10 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-cdrom:1 description: DVD writer product: DVDRRW GWA-4164B vendor: HL-DT-ST physical id: 0.1.0 bus info: scsi@0:0.1.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/scd1 logical name: /dev/sr1 version: 1.01 serial: [HL-DT-STDVDRRW GWA-4164B1.0105/05/12 capabilities: removable audio cd-r cd-rw dvd dvd-r configuration: ansiversion=5 status=nodisc Is t detecting all drives or thise local names just same

• Measuring performance indicators on a cluster

  - by Aditya Singh

  My architecture is based on Amazon. A ELB load balancer balances POST requests among m1.large instances. Every instance has a nginx server on port 80 which distributes the requests to 4 python-tornado servers on backend which handle the request. These tornado servers are taking about 5 - 10ms to respond to one request but this is the internal compute time of every request. I want to put this thing on test and i want to measure the response time from ELB to upstream and back and how does it vary when the QPS throughput is increased and plot a graph of Time vs. QPS vs. Latency and other factors like CPU and Memory. Is there a software to do that or should i log everything somewhere with latency checks and then analyze the whole log to get the stuff out. I would also need to write a self-monitor which keeps checking the whole response time. Is it possible to do it with a script from within the server. If so, will it be accurate ?

• What can I do to determine the root cause of a Windows server hanging/freezing?

  - by Aaronaught

  We set up a new server here a few weeks ago that I am informally responsible for managing. Almost everything works perfectly except for one thing: Every so often it hangs without warning. To clarify: When I say hangs, I mean completely. None of the services respond and I'm unable to even get onto a local console - the display acts as though there's no VGA signal. One time, the server actually responded to pings, another time I got the "destination host unreachable" response, but most of the time the pings just time out, as one would expect for a hung server. Event logs don't show anything after a reboot. I don't mean that they don't show anything interesting, I mean that they don't show anything at all from before the failure occurs to after the reboot. And there are never any performance problems, strange errors, or other obvious signs of impending doom before it happens. I don't expect any easy answers here. What I'd like to know his I can methodically determine the root cause of this problem, be it a misbehaving service, defective hardware, or something else. Is there any kind of logging I can set up that will help me get to the bottom of this? Any hardware diagnostics or remote monitoring? Anything else I can do to help me discover what's actually happening, or at least be able to eliminate what isn't wrong? Just to reiterate, I really don't want to start speculating about possible causes and take a trial-and-error approach, because it's going to be at least several days at a time before I would have conclusive results. I'm looking for solutions to reliably trace the problem to its source.

• Fast extraction of a time range from syslog logfile?

  - by mike

  I've got a logfile in the standard syslog format. It looks like this, except with hundreds of lines per second: Jan 11 07:48:46 blahblahblah... Jan 11 07:49:00 blahblahblah... Jan 11 07:50:13 blahblahblah... Jan 11 07:51:22 blahblahblah... Jan 11 07:58:04 blahblahblah... It doesn't roll at exactly midnight, but it'll never have more than two days in it. I often have to extract a timeslice from this file. I'd like to write a general-purpose script for this, that I can call like: $ timegrep 22:30-02:00 /logs/something.log ...and have it pull out the lines from 22:30, onward across the midnight boundary, until 2am the next day. There are a few caveats: I don't want to have to bother typing the date(s) on the command line, just the times. The program should be smart enough to figure them out. The log date format doesn't include the year, so it should guess based on the current year, but nonetheless do the right thing around New Year's Day. I want it to be fast -- it should use the fact that the lines are in order to seek around in the file and use a binary search. Before I spend a bunch of time writing this, does it already exist?

• How to see the properties of a DOM element as they change in realtime?

  - by allquixotic

  JavaScript code can update the properties/attributes of DOM elements in real time by responding to events and so on. Here is an example. In the table on that page, move your mouse over the cells. Notice how they change color when the mouse is on them, and the color goes away when you move the mouse to another cell. Now, using Firefox or Chrome (but not IE, Opera, etc.), I want to examine the background color, expressed in RGB or hex or whatever, of the cells updated in real time, as the mouse cursor enters and leaves the region and causes the JS to do its thing. The behavior that I observe, currently, is that the Inspect Element functionality of both Firefox and Chrome does not update the value of the properties as they are updated by JavaScript. So, in order to view the latest value of the property, I have to inspect the element again, and it takes a momentary "snapshot" of the values. But since the values only change while I have the mouse on them, I can't take a snapshot of the value I want while my mouse cursor is over the cell, because I have to remove my mouse from the cell to select the "Inspect Element" item in the right-click list! If it is possible to have the values updated in real time using either Firefox or Chrome, or an extension, on any recent version of the software (up to the latest stable), please provide instructions for doing so.

• Moving a site from IIs6 to IIS7.5

  - by Sukotto

  I need to move a site off of IIS6 (Win Server 2003) and onto IIS7.5 (Win Server 2008) as soon as possible. Preferably tomorrow. The site itself is a delightful mix of classic asp (vbscript) and one-off asp.net (C#) applications (each asp.net app is in its own virtual dir and has a self-contained web.config). In case it's relevant, this is a sort of research site made up of 40 or 50 unconnected microsites. Each microsite is typically a simple form allowing a user to submit a form, which then runs a Stored Proc on a sqlserver db and displays a chart and/or table of the results. There is very little security to worry about. The database connection info is in a central file (in the case of the classic asp) or app's individual web.config (lots of duplication there) To add a little spice to the exercise... I have no idea how to admin IIS The company no longer employs the sysadmin or the guys who set this thing up. (They're not going to employ me much longer either but my sense of professional pride does not permit me to just walk away from this task). The servers are on mutually firewalled networks and I have to perform a convoluted, multi-step process to copy anything from one to the other. Would someone please point me to a crash-course tutorial for accomplishing the above? I have: a complete copy of the site's filesystem on the new box installed the 3rd party charting tool on the new system a config.xml file from the "all tasks - save configuration to a file" right click menu. There doesn't seem to be a way to import it on the new system however. The newer IIS manager has a completely different UI and I'm totally lost. Please help.

• Troubleshooting my internet connection

  - by Simon Verbeke

  While I was out of the house, my father rearranged the network cables a bit. I don't know what he has done exactly - He says nothing more then pulling and untangling. When I came back home, my internet connection changed its IP from 192.168.0.205 to 169.254.197.233. The speed changed from 1Gbps to 10Mbps. It has also been at 100Mbps for a while. My subnetmask changed from 255.255.255.0 to 255.255.0.0. The standard gateway changed from 192.168.0.1 to no standard gateway. My DNS servers remain the same. I have checked the lights of the UTP ports, and it looks like it's only sending a heartbeat every few seconds. A sketch of the (relevant part of) the network: My PC ----- extender ----- modem ^ ^ ^ Wired | Wired | This thing connects two cables to each other All the cabling is gigabit, my network card is a Realtek RTL8168C(P)/8111(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20). THe modem is a CBN SVG6540E I have no idea what is going on here and I don't know how to find out either. Any help is welcome! If you need any more info, please ask.

• Network switches for LAN party

  - by guywhoneedsahand

  I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

• Is there a historical computer peripherals or accessories museum or even just a current list?

  - by zimmer62

  Thinking about all the unique and different peripherals I've owned over the years, from ISA capture cards, to parallel port controlled shutter glasses for 3d games. I've seen many many accessory or computer peripherals come and go. The nostalgia of these things is a lot of fun. I tried to find some sort of historical time-line or list but what mostly turned up is computers themselves. I'm more interested in the mice, scanners, the weird adapters that shouldn't exist, short run very rare products, strange devices from computer shows in the 80's and 90's... Hardware you might find in a geeks basement that would be completely useless now, but was the coolest thing around when it was new. An example would be a drawing tablet I had for my TI-99 computer, or the audio tape player accessory for a C64 which let you save files to audio tapes, An ISA card that did the same for PC's hooked up to a VCR. Remember that IBM-PC Jr upgrade kit, that added a floppy drive, more memory and the AT switch in the back? I'd love to find either a wiki, or a list that has already been assembled which contain many of these weird (or common) accessories. I've had so many over the years I suppose I could start a wiki here if such a list doesn't already exist.

• Only one domain is not resolving via Windows DNS server at multiple locations, but is at others

  - by Brett G

  I'm having quite a weird issue. Had mail delivery issues to a specific domain. After looking closer, I realized that the DNS for that domain isn't resolving via the in-house Windows 2003 SP2 DNS server. C:\>nslookup foodmix.net Server: DC.DOMAIN.com Address: 10.1.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DC.DOMAIN.com timed-out (DC.DOMAIN.com and 10.1.1.1 are generic values to replace the actual ones) Even if I run this nslookup from the DC.DOMAIN.com server, I get the same result. However, all other requests are working as they should. I had a sysadmin friend try this DNS lookup on servers at several companies that he consults for (which are also Windows 2003 AD servers). The weird thing is some of these were having the same exact issue. However using public DNS servers work. I have tried clearing the DNS cache, restarting the server, restarting the services, etc. Nothing has worked. One weird event I noticed in the DNS Server Event Logs that might be related is an event ID of 5504 with the following description: The DNS server encountered an invalid domain name in a packet from 192.33.4.12. The packet will be rejected. The event data contains the DNS packet. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. In the data section below, I can see the following mentioned: ns2.webhostingstar.com Which happens to be the nameserver for the domain in question. Several discussion threads and a MS KB have pointed to disabling EDNS. I have done this via "dnscmd /config /enableednsprobes 0" and it has not fixed the issue.

• processes slow after some time of actively running

  - by Yervand Aghababyan

  i have several cron jobs running on an ubuntu machine. each one does some pretty heavy load stuff. The cron jobs are parsing files and the bigger the file the longer it takes them to parse it. The strange thing is that if i make the files too big ( like 30mb) the script kind of hangs. It starts processing them really enthusiastically but after some time (something like 5-10 minutes) the cpu usage of the process drops a lot and it gets into some "zombie" state. If prior to this the process in htop was using 70-80% of the CPU then after this drop occurs it slows down to something like 5-10%. the load average drops down as well. The status of the processes sometimes changes to D in htop, which AFAIR stands for zombie. Today i noticed the same behavior of processes of mysql when executing heavy queries (a query took something like 4 hours to execute). the cron jobs are mostly php and during their processing most of the CPU eats the php process and not mysql. so i think the issue is not with a specific language/program but with the way the processes are "managed". The only other place i've seen similar behavior was on my Amazon EC2 micro instance when after some aggressive use of CPU the CPU quota was taking effect and everything was slowing down dramatically. This is a dedicated machine running ubuntu. what may be the cause?

• Monitor flickers in native resolution.

  - by ptikobj

  With my new Samsung Syncmaster BX2450 I have the following problem: In Windows XP (SP2), all resolutions above 1440x900 have either strange pixel errors or an extreme flickering. It seems, that the effect worsens for higher resolutions. In special, I would like to run the monitor with its native resolution (1920x1080), however I can't watch longer than 5 seconds on the monitor because of the flickering... My Graphics Card is a Geforce FX 5200 with the most up-to-date driver (according to Nvidia.com: Forceware 175.19) and I'm having the monitor connected to its DVI-output. The strange thing is, under Ubuntu 10.04, all resolutions work just perfect, so the display must be alright. edit: seems to be a driver problem... if I use the proprietary NVIDIA drivers in Ubuntu, I have the same problem as in Windows. I would like to reformulate my question: Is there a modified/alternative Geforce FX 5200 driver (as there is in Ubuntu) for Windows that allows me to use 1920x1020 without problems ? I already tried the omega drivers: unfortunately, it still looks poor on the native resolution.

• Whats the difference between pulling from a branch into master and pushing that branch onto master?

  - by Justin808

  In Tortoisegit, on the repository, I right-click and select sync. At the top of the dialog there are options for Local Branch and Remote Branch. If the local branch is named DeveloperA and the remote branch is master and I do a push, what happens? If the local branch is master and remote branch is DeveloperA and I Pull, what happens? If I am on the master branch and right click, select Merge and change the From to be my DeveloperA branch, what happens? If I try to push from master to remote master and the remote is updated git stops and tells me to pull. It seems if I push from DeveloperA to master it doens't stop, it just clobbers, it that correct? We're having an issue using git where the remote master branch gets clobbered at times and we are trying to figure out why. For example there is a developer working on his DeveloperA branch. He'll pull from master to get any updates, then push to master to push out his changes. But there are times that the push lists more files in the Out Commit list than he's edited. The odd thing is he can't revert those files as git is saying they are up to date and have not been modified. Yet when he pushes git pushes the files out. The problem is if there are changes between his pull and push the changes get clobbered.

• PuTTY inserts random characters during a session

  - by Zachary Polikarpus

  I recently started renting space on a remote server so that I could work on a project. I found that a relatively painless way to access it on a windows machine is through PuTTY. However, there is one thing that has always irked me when using it: for seemingly no reason random characters are sometimes inserted at the cursor. Most of the time it is just a single tilde, but rarely it spits out what looks like some escape sequence ([[^8 or the like). It will only occur when I am focused on the window, whether I am typing or 20 feet away from the keyboard. If left for long enough, it will spit tildes at random intervals (average is about 1 minute). Finally, this behavior seems to be inconsistant when running programs such as nano or the mysql interface: in nano, instead of inserting tildes, it will set marks (ctrl-^); in mysql, lines will become un-editable. My question is this: Has anyone else experienced this sort of behavior in PuTTY? And if so, what can be done to prevent/correct this behavior?

• Centos repository packages vs latest developer release

  - by fran

  I have started to run a personal server using CentOS and I have noticed that many packages that are available to install from repository are old compared with the latest release from the developer. I know that installing packages from repository is very easy and I guess that the supplied versions are stable and prepared to work without any trouble, but I still find odd having so much software that lags behind the current version. It's my first time with linux and I don't know what is the "normal" thing, should I stick to whatever version the repository supplies, or try to get the latest from the developer? To be more precisely, the repository supplies the apache httpd web server with version 2.2, I wanted to update to 2.4, so I started removing apache and its dependencies packages that come with centos to use the latest ones, but when I was about to remove pcre v6 to replace it with v8, i found out that 132 installed packages depend on it and probably it is not a good idea to remove it, so that made me think twice about getting the latest software instead of using the packages supplied by the official repositories. Should I leave things as they are instead of going on an upgrade rampage? Thanks

• No sound Ubuntu 10.10 (have SB Live! card)

  - by Chris Frazier

  I am new to Linux/Ubuntu and I just installed 10.10 on my Dell Desktop PC that was running Windows XP. The PC is about 5-6 years old and the sound card it has is a SoundBlaster Live! card. The Sound Preferences recognizes the card as [SB Live! Value] EMU10k1X. It is currently set to Analog Stereo Duplex. I tried multiple other sound configurations and nothing works. No sound but some clicks come out of the speakers. I ran the system test and during the audio tests the same thing happened, just clicks and pops. I tried to play some music with Rhythmbox and when it tries to play a track it tries for several seconds and then just closes itself, or sometimes just doesn't play. I ran a check for drivers, but the only driver it found to install was for my nVidia video card. It did not show any drivers for the sound card. Does anyone have any idea what I need to do to get the sound to work?

• nginx logrotate config

  - by TomOP

  Whats the best way to rotate nginx logfiles? In my opinion, I should create a file "nginx" in /etc/logrotate.d/ and fill it with the following code and do a /etc/init.d/syslog restart after that. This would be my config (I havn't tested it yet): /usr/local/nginx/logs/*.log { #rotate the logfile(s) daily daily # adds extension like YYYYMMDD instead of simply adding a number dateext # If log file is missing, go on to next one without issuing an error msg missingok # Save logfiles for the last 49 days rotate 49 # Old versions of log files are compressed with gzip compress # Postpone compression of the previous log file to the next rotation cycle delaycompress # Do not rotate the log if it is empty notifempty # create mode owner group create 644 nginx nginx #after logfile is rotated and nginx.pid exists, send the USR1 signal postrotate [ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` endscript } I have both the access.log and error.log files in /usr/local/nginx/logs/ and want to rotate both daily. Can anyone please tell me if "dateext" is correct? I want the log filename to be something like "access.log-2010-12-04". One more thing: Can I do the log rotation every day on a specific time (e.g. 11 pm)? If so, how? Thanks.

• Why is my server performance degrading to the point of stopping, periodically?

  - by Pascal Aschwanden

  So, once in a while, I see in firebug that a request takes over 15 or even 60 seconds to respond and sometimes never. Here is what I've ruled out: It's not the CPU, cuz every time I check the Server load its less then 6 for all 3 numbers It's not the memory, because thats fairly low too, less the 50% It's not the I/O anymore, because I've seen the graphs that Joyent sent back to me when I requested them, and they show less then 3MB of I/O (mostly all read). It's not the SQL performance - I've profiled every last SQL command that runs, and they're all (99.9% of them anyway) running in less then 30ms, most run in less then 5ms. Oh and I've been profiling all the script execution times, and even the when the problem occurs, the script always manages to finish in 50ms or less (that's 1 / 20th of a second ). Now, I do run alot of ajax calls. 1 every 2 seconds per user and I have 300 DAU+. But, even if all 300 are playing simultaneously, thats still only 150 calls per second max. The only other thing I can think of is that one of my neighbors is funky. The problem is highly intermittent. 99% of the time it works perfectly and there's excellent performance. but 99%+ is not good enough. Eventually the performance gets so bad I have to restart the server, at which point everything is fine again. I've done this about 4 times now. Any ideas? Note: this is on joyent, vps, intro package 256mb of ram with bursting. here are the mysql dump info: Traffic ø per hour Received 18 MiB 29 MiB Sent 134 MiB 221 MiB Total 151 MiB 251 MiB Connections ø per hour % max. concurrent connections 5 --- --- Failed attempts 0 0.00 0.00% Aborted 0 0.00 0.00% Total 9,418 15.59 k 100.00%

• Windows 7 - media sharing extremely flakey (XBox 360)

  - by Nathan Ridley

  I have constant headaches with Windows Media Library sharing, which I'm using to share my video library (a whole lot of AVI files on my computer's hard drive) with the XBox 360. I have the whole setup working, so setup and basic configuration is not an issue. The issue is that Windows Media Library frequently fails to notice additions and modifications to the "watched" folders. Not only that, but often after I've added something new to the library, it fails to transmit this new library information to the 360, as is demonstrated by the fact that, using that 360, I navigate to my video library and the new folders don't show up in the list. Often the only way to get the 360 to see the changes is to exit out of "Videos" on the 360, then remove all videos from Windows Media Library, go back into videos on the 360 to confirm that nothing is shared, then re-add a few videos (but not too many) in Windows Media Library, then go back into the videos in the 360. The whole thing is a real pain in the bum and I really wish I could just add all my videos to Windows Media Library and have it keep watch without me having to kick it, and have the 360 pick up changes without me having to constantly rebuild the library. Any ideas?

• nginx hackery : change image file every X request

  - by Vangel

  Let me describe what I am trying to do first. I have a bunch of pictures in a directory called /images/*.(jpg|gif|png|blah blah|) Now say these images are embedded in an html page and I dont really care which image or where its embedded. For every 10th request for the same picture file (if possible) or for any picture I want to display a fixed image (e.g. trollface.jpg). thats it! I have searched around a bit but i am not even sure what I am looking for. Rewrite might help but then its a permanent thing. this has got to do something with requests. I have heard perl scripts can be used with nginx. I can't write an nginx module (though I did bravely lookup the docs and then gave up) Before you ask "But why don't you do it in application, noob?". This is a static files only server. The point is to not execute any binary at all.

• Map a URL bought with Dreamhost to Amazon EC2 (AWS)

  - by Edan Maor

  I have several URLs I purchased through Dreamhost. I'm starting to use Amazon's AWS, and I'd like to map the URLs to Amazon. This is something of a silly question, and I've already done the same thing several times to other services (mapping from Dreamhost to WebFaction). But for some reason when I tried to find the proper way to do the same mapping to Amazon, I find a lot of detailed writing talking about whether I should be using CNAME or A records, etc. So I wanted to ask in the simplest possible terms and hopefully get a simple, concrete answer: I bought a URL from Dreamhost, I have an EC2 server running on AWS (to which I already mapped an Elastic IP address). How do I make the URL map to AWS? And if there are several options, which one should I effectively be using? P.S. Meta-question - why are things so much more difficult with AWS? When I search Google for "Move from Dreamhost to WebFaction, I get very simple answers on how to do the mapping. In what way is AWS different?

• Why can't I debug my ASP project through a remote desktop connection?

  - by Anthony Benavente

  I just asked this question in Stack Overflow but I figured this stack exchange forum is a better fit. It's been about a month of trying to figure out this problem and we've still not found a solution. We have about seven virtual machines on a server running Windows XP Professional w/ SP 3 all with Visual Studio Interdev and IIS 5.1 installed. Running the programs all work fine, but we just can't debug through remote desktop. When we are logged into the server console (through VM Sphere) and log into one of the virtual machines through there, we are able to debug properly. We figured the issue lies with some kind of permissions for Remote Desktop Users. We've tried nearly every article on the internet (exaggerating of course) and are about to give up hope. One more thing, when we are logged into the virtual machine through the server console and then remote in, the user that was logged into the console is kicked off but debugging works! Does remoting in trick the computer into giving us the correct permissions? I'm really not sure how it works. I know that this technology predates human history, but we are in the process of migrating from ASP Classic to ASP.NET Specs: - Windows XP Professional W/ SP3 - IIS 5.1 - Visual Studio 6 Interdev EDIT: By "debug" I mean running the project with breakpoints. Interdev doesn't stop at breakpoints.

• Soundtest works, but no other sounds and windows starts very slowly

  - by Kristian Kari

  So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

• vSphere Promiscuous mode only receiving packets one way from network switch

  - by steve.lippert

  We have two network switches, a POE switch (SwitchA) to power our phones / users computers and a non-POE switch (SwitchB for the rest network.) Each switch is setup to do port mirroring to support our VoIP recording system. SwitchA does port mirroring on specific ports if we need to record a user. SwitchB mirrors one port to monitor our work at home users (Internet comes in from managed router, to switch, back out to our firewall.) These two port mirroring setups feed into one vmware vSphere 4.1 server, it has four total physical cards. The other two NICs feed into an unmanaged switch for connecting to the rest of the network. Once into the vSphere server all network ports go into a vSwitch, and then one of the servers (Windows 2008 R2) sniffs them out and does its thing. Everything is working fine and dandy from SwitchB. But on SwitchA we only receive one side of the VoIP packets (going out to the phone, nothing coming in from the phone). Troubleshooting steps I have taken so far: I hooked up my laptop to the monitor port on SwitchB and I see both sides of the packets. I swapped which network interface is plugged into the monitor port on SwitchA. Because everything feeds into one vSwitch / vNetwork and both sides of the conversation arrive just fine from SwitchB I believe everything is configured correctly on the vSphere server/guest. What could be causing one way packets to arrive on my guest machine from only one interface, but not the other? Could a bad cable be causing the problems from SwitchB?

• W7-pro indexing mydoc on disk partition does not work

  - by Yvan Thery

  I am working on a HP-7100 mini tower running W7 Pro 64bits. My Local HD includes C:/ + 2 disk partitions : all my documents are located on disk partition L:/ and all my media files are on disk partition M:/ The indexing process works well on C:/ and M:/ but does not index the L:/ any more also all of them are allowed to be indexed, also the system is present on all drive security tabs. I have tested to rebuilt the indexing file with a new setting including few directories present on drive C/M/L but still with L: does not work ! One more thing I can tell you is that even after rebuilding the indexing file, I can find some residual directories or files which are out of the test selection. It is like unerased components remaining in the indexing database. As I do not know precisely how the indexing process works it is hard to know what to do ... Recently I had a bad time after using a past restoration procedure ... maybe it did corrupt the indexing file ???? If I start indexing the all L:/ disk partition the system stop at 39 found index also many more are existing .... Does any one from you guys could advise the process to create a new indexing database ... ? Any idea to get out of this mess ? Many thanks for assistance Yvan
