  • hardware: delay and distinct 'click' before hard drive access

    - by matt lohkamp
    I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

  • Port mirroring on multiple switches

    - by Matt
    So here is the deal, I have a server on switch A where port 3 is monitoring traffic for most of the ports on switch A. However I have other users on switch B that needs to have port 3 on switch A monitor as well. Is this possible? I have been reading about rspan but doesnt seem to work. Switch A: monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 (this works great for switch A, I need a solution to get switch B to also have some ports sent to port 3 on switch A for monitoring.) Onxx, All the traffic on switch A is fine, there will be about 10-15 ports on switch B that I need to send to fa0/3 on switch A as the destination. I have the switches connected with a ethernet cable with a trunk port on both switches on port 48 on switch B and A and port 47 on A connects to our sonicwall. So I am assuming they are daisy chained? What if I did the following: Switch A monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 Put all of the ports on vlan 10 because I made an rspan vlan 10 On switch B monitor the ports I need will say 1-10 monitor session 1 source interface fast0/1 - 10 monitor session 1 destination remote vlan 10 as a prerequisite I would have created vlan 10 as a rspan vlan on switch B. Switch A Monitor session 1 destination remote vlan 10 Would this work? By the way I am working with cisco catalyst 3560 switches.

  • What is causing my internet to be slow on one laptop but not the other and only at a distance?

    - by Matt Case
    I have a newer laptop, purchased within the last year (acer aspire 7740). This laptop does not have any problem connecting to wireless networks and indicates that the signal strength is excellent on most of the wireless networks I connect to. When the laptop is within 10 feet of my wireless router it gets 30 down 10 up. When it is farther away than 10 feet it will be lucky to get 3 down and 1 up. I also have an older laptop, purchased in 2005, that has no problems at all at the same range. None of my phones, gaming consoles or tablets have this problem. I am beginning to think that the problem must be some hardware defect with the wireless card. I can provide additional information if needed. Just thought I'd check to see what others thought because I've been working on computers my whole life and have never heard of this happening. I have also tried to change the channels on my wireless router and have had no success with this idea.

  • SBS2011 Standard DNS suddenly not resolving some domains

    - by Matt
    Suddenly today I am unable to resolve common domains like serverfault.com, facebook.com; but other domains like google.com, cnn.com work fine. This is on a client machine (Win7 Pro) connected to an SBS2011 Standard domain. The only DNS server is the SBS2011 server. The same domains work fine on all client PCs I have tried, and the same ones do not work. Using nslookup, I get 'no such domain' errors for facebook.com, and the correct DNS entries for the ones that do work. When I add Google's Public DNS to my client PC as a backup (primary = local SBS server, secondary = 8.8.8.8), everything works fine for my client PC, but querying from the SBS server directly or from other client PCs are broken (so I don't believe it's a firewall issue). My main question is how can I see what servers the SBS2011 server queries if it doesn't know about a domain? There is nothing in our firewall logs that say it blocked any DNS-based packets, but I also wanted to query based on the IP/FQDN on the servers that the SBS server was likely to contact to find out about facebook.com for example. Update 23/05/2012: It appears DNS is working again this morning for the affected websites. Both the DC on its own and all client PCs can once again access the websites that were not loading last night, as well as the websites that were working. I haven't changed anything overnight, so it appears that there was some kind of temporary glitch, but I can't understand what would have caused it on the network.

  • Domain Controller Placement

    - by Matt
    I've been working through some Exchange training documentation (the official MS e-learning package) and all of the design scenarios allude to placing at least one DC from your forest root domain in every site. I'm not sure whether this just relates to Exchange, but I can think of a number of issues we experience in our forest that would be resolved by this. For example, a Microsoft support engineer has stated that EVERY client in a child domain (i.e. all workstations and member servers) need access to a forest root DC to check certificate/template permissions, even on a subordinate CA. I have attempted to locate documentation or guidelines from Microsoft on this, but have not been able to find anything. I found the Domain Controller Placement guide, but it's only a form - you would use it to document where you will place your DCs, but it doesn't give any guidance on where you should deploy them. Does anyone know where, or if, I can find any such documentation?

  • Setting XFCE terminal PS1 value and making it permanent

    - by Matt
    I'm trying to add the value PS1='\u@\h: \w\$ ' to my terminal in XFCE. I added the line to (what I think is) the correct area in /etc/profile. The relevant segment is: # Set a default shell prompt: #PS1='`hostname`:`pwd`# ' PS1='\u@\h: \w\$ ' if [ "$SHELL" = "/bin/pdksh" ]; then # PS1='! $ ' PS1='\u@\h: \w\$ ' elif [ "$SHELL" = "/bin/ksh" ]; then # PS1='! ${PWD/#$HOME/~}$ ' PS1='\u@\h: \w\$ ' elif [ "$SHELL" = "/bin/zsh" ]; then # PS1='%n@%m:%~%# ' PS1='\u@\h: \w\$ ' elif [ "$SHELL" = "/bin/ash" ]; then # PS1='$ ' PS1='\u@\h: \w\$ ' else PS1='\u@\h: \w\$ ' fi Most of that was already there, I just commented out the existing value and added the one I want. By manually opening the terminal and doing . profile, I can load these values, but they don't stick - I close the terminal and reopen, and I'm back to sh-4.1$. Maybe I'm doing this in the wrong place, but how can I make that value stick? All the info I've found on google is Fedora/Ubuntu-specific. I use Slackware. Any help on this matter would be greatly appreciated.

  • looping .mpeg dump

    - by Matt Cook
    Need to dump an MPEG2 file in a loop, either to stdout or a named pipe. This works: $ { while : ; do cat myLoop.mpg; done; } | vlc - This works on a text file containing "1234\n": $ mkfifo myPipe $ cat test.txt > myPipe & < myPipe tee -a myPipe | cat - (it correctly loops, outputting "1234" on every line). Why does the following NOT work? $ cat myLoop.mpg > myPipe & < myPipe tee -a myPipe | vlc myPipe I'm primarily interested in re-writing the first statement to remove the improper "cat myLoop.mpg" statement. Will be inputting into VLC, or into FFMPEG and then piped into VLC.

  • Grouping extensions in Asterisk

    - by Matt
    We have an asterisk based phone system with multiple clients connected to it. At the moment, all the extension numbers fall in the range 100 - 9999. But, now we have an issue where a particular customer wants to come onto our service and insists on keeping their existing extension list. Is there a way of having extensions 700 for one customer, and also the same number range to another customer. But yet having them belong to a different group? I see there is a concept of groups in asterisk but none of them seem to provide a solution to this.

  • Get the RSS/XML feed for an iTunes U Podcast to use in another podcatcher

    - by matt
    There are numerous ways to get the podcast feed for standard iTunes podcasts like this or this, however, neither of these methods work on the podcast feeds in iTunes U. I don't want to use iTunes, how can I find the alternative xml podcast feed? Here's one for example: http://deimos3.apple.com/WebObjects/Core.woa/Feed/fora.tv.1901773207.01901773213 How can I subscribe to this feed outside of iTunes? I have tried emailing the publisher (Fora.tv) numerous times but they never respond.

  • Can I group rows to get sum using excel

    - by Matt
    I have a spreadsheet with 2 cols of importance. Date, and number. I can't always predict the number of rows or the date, but what I would like to do is print out the sum of the numbers for each date. For example, there might be 5 rows for Dec-7: 200, 111 and Dec-6: 222,533,100. I am tying to create a list which would show Dec-6: 855, Dec-7: 311. I believe a Pivot Table is what I want but I can't quite figure out how I need to configure it to show what I want. If anyone knows of a guide I could look at that would be fantastic!

  • change internet hotkey

    - by Matt
    My laptop (Acer Aspire 6930) has a hotkey to open the web browser. However, I just got Firefox and I was wondering how I can change the hotkey so that it opens Firefox instead of Internet Explorer. I already contacted Acer...they told me to phone them (at cost), which I would rather avoid since it's such a trivial matter.

  • Can't open shared drive after disconnecting vpn

    - by Matt McMinn
    I use a VPN to connect to my office network. On my local network I have another WinXP machine that shares a printer and a few shared folders. While I'm connected to my work VPN, I can access the shared printer and folders on the other machine just fine, and vice versa. Once I disconnect the VPN, I can't access the local machine any more, and the other machine can't access my machine. The network itself seems ok - I can ping the other machine, get to the internet, and get on to a web server shared by the other machine, but I can't get to the shared folders or printer. If I reconnect to the VPN, my access is restored. I'm guessing this is some sort of authentication thing, but I don't know what. Any ideas? Update This problem is bothering me again, so here's an update. Depending on when I first access the WinXP machine, I either have this problem, or the opposite problem. After a reboot, if I (for example) print, then connect to the VPN, I can't access the machine while on the VPN. If after a reboot I connect to the VPN, then print, I can't access the machine off the VPN. In both cases, if I enable/disable the VPN again, I can access the machine again. Thanks

  • Show & Hide hidden files on demand in Windows

    - by matt wilkie
    A little while ago I discovered that on Ubuntu linux one can display or conceal hidden files on demand at run-time by pressing [Ctrl-H]. This is really handy. Is there anyway this can be had on windows? I'm guessing Windows Explorer is not amenable to this, so I'm open to 3rd party file managers provided they're open source, freeware, or cheap (in order of preference). thanks

  • Windows 2008 Server Unable to activate with other methods

    - by matt king
    I'm trying to activate windows 2008 server SP2 today since the activation trial is done. I do not have an internet connection with this server so I can not activate online, and with the other servers in this farm I've been able to run the slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx and then it would open up the activate by phone method and we would just activate that way. I say again, I don't have an internet connection so I can not do the online activate. If I do the slui 4 it brings up the activation window but show me other ways to activate is still greyed out. I've disabled the NIC on this Hyper-V server and I still can not get the other way to activate to show up... Anyone have any ideas? This computer is one of my AD servers so.. it being in notification mode kind of sucks. Thanks.

  • SSD not detected on boot up running windows 7, with installed blank hdd

    - by Matt. G
    I have recently built a PC for a friend, after the original system build, which included a 60GB primary SSD and a secondary 1TB HDD. I kept getting blue screens of death and kernel power errors, after investigation it was revealed that a faulty power cable and insufficient thermal paste provided with the included heat sink was the cause. This resolved the problem but after 3 months I received a phone call saying that the PC was not starting at the point of loading the operating system, with an NTLDR error. I had an idea of the cause, and after the user removed the HDD the computer started up with no issues, then I asked him to power off and reattach the HDD, and this completely resolved the issue; beforehand even restarting would not fix it. He does not have a surge protector and I thought that maybe some registry corruption had occurred due to a power surge, this might be a stupid answer though. Any ideas to what occurred with the machine would be most appreciated. No other issues have been found since the initial fault. The PC uses Windows 7 Home Premium installed on the SSD.

  • Are there HP Infinihost III ex drivers for windows available?

    - by Matt
    I picked up some infiniband cards off ebay for development/testing purposes. I was hoping that there would be some drivers available under windows 7, but it doesn't seem to be recognised by the OFED software which would seem to contain windows drivers. They are however immediately picked up by Ubuntu and drivers are loaded. Are these cards supported under windows 7 at all? mstflint under linux reports: Image type: Failsafe FW Version: 4.8.930 I.S.

  • Multiple subdomains resolving to one domain?

    - by Matt
    I'm trying to host an application, but allow the customer to use their own sub domain so that it does not confuse their own customers. So for example, by application would run on app.mydomain.com, but my customer would access it via their own subdomain (app.somedomain.com and/or app.anotherdomain.com). Is this even possible? (Possibly relevant information: my application is hosted on media temple and uses Apache) Thanks!

  • Which ports for IPSEC/LT2P?

    - by Matt
    I have a firewall/router (not doing NAT). I've googled and seen conflicting answers. It seems UDP 500 is the common one. But the others are confusing. 1701, 4500. And some say I need to also allow gre 50, or 47, or 50 & 51. Ok, which ports are the correct ones for IPSec/L2TP to work in a routed environment without NAT? i.e. I want to use the built in windows client to connect to a VPN behind this router/firewall.

  • Notepad++ tabbing out of tags, autocomplete

    - by Matt
    I'm trying to learn a little HTML. Everyone says to use Notepad++ over notepad. I have autocomplete on. My question: When I type my opening tag and Notepad++ then puts"""" closing tag, how do I "jump" out of the tag when I'm done typing? If I tab or hit enter, I'm still stuck before the closing tag. I can use my arrow keys, but if I'm going to do that, I would rather just type the closing tags. Also if I have an UL of 10 items, and I want to change it to an OL, how do I select both the opening and closing tags so I may edit them at the same time? Thanks PS I wasn't able to post the HTML tags.

  • Why does pinging a local router return "Destination Host Unreachable"?

    - by Matt H
    I have two tomato routers. One is bridged wirelessly with the other. I have a new server on the network. It's running Ubuntu Server 11.04. They are all connected like this: A - Linux PC B - New Server C - Mac Mini D - Macbook T1 - Tomato 1 T2 - Tomato 2 They are connected like so: A -----+-T1 ==== wireless bridge ==== T2----- ADSL modem | | C & D Connected wirelessly to T2 B -----+ A, C & D do not experience any issues. I have an active SSH session to B from A and it's not experiencing any loss. B, the new server occasionally cannot ping T2 and therefore cannot connect to the internet. However, A can always contact B and B can ping A and B When the network is lost, B can still ping T1, but not T2 yet at the same as B has lost connection to T2, A can still ping T2. Any ideas on what this could be? there is nothing that gives any clues in any of the logs on either router or the linux server. One thing that is interesting is that I set up a ping running between B and T2. T2 has the IP address 192.68.1.1 Here is what I am seeing: From 192.168.1.1 icmp_seq=26 Destination Host Unreachable From 192.168.1.1 icmp_seq=27 Destination Host Unreachable From 192.168.1.1 icmp_seq=28 Destination Host Unreachable From 192.168.1.1 icmp_seq=29 Destination Host Unreachable From 192.168.1.1 icmp_seq=30 Destination Host Unreachable From 192.168.1.1 icmp_seq=31 Destination Host Unreachable From 192.168.1.1 icmp_seq=33 Destination Host Unreachable From 192.168.1.1 icmp_seq=34 Destination Host Unreachable From 192.168.1.1 icmp_seq=35 Destination Host Unreachable 64 bytes from 192.168.1.1: icmp_req=36 ttl=63 time=3.40 ms 64 bytes from 192.168.1.1: icmp_req=37 ttl=63 time=5.70 ms 64 bytes from 192.168.1.1: icmp_req=38 ttl=63 time=2.25 ms 64 bytes from 192.168.1.1: icmp_req=39 ttl=63 time=2.18 ms 64 bytes from 192.168.1.1: icmp_req=40 ttl=63 time=3.12 ms 64 bytes from 192.168.1.1: icmp_req=41 ttl=63 time=2.15 ms 64 bytes from 192.168.1.1: icmp_req=42 ttl=63 time=1.97 ms 64 bytes from 192.168.1.1: icmp_req=43 ttl=63 time= And it cycles to being reachable and not. So I guess you could say the question is, why is the router responding that it cannot be reached?

  • Windows 7 Explorer: how to show total size of all files in current folder?

    - by matt wilkie
    In Windows XP Explorer one can turn on Status Bar which shows, among other things, the total size of all the files in the current folder, or if the cumulative size of the selected files. How do I get the same at-a-glance information in Windows 7? Selecting files doesn't count as it stops after 15 files, and it's rare that I'm concerned about total size with that few files (it's pretty easy to estimate in my head). thanks. UPDATE: Information derived from the context menu (select r-click properties) isn't "at a glance", and not as smooth as selecting files and clicking the details link at the bottom in any case. Thank you for fleshing out more of the available routes though. Yes Q19232 is similar to this one, though it is not a duplicate. That question is about looking for easy free-space on disk stats and this one is easy used-space by contents of this folder stats. The answer for both is the same though. You can't! Hopefully someone will figure how to get this lost feature back with a shell extension or something.
