• Routing Essentials

  - by zharvey

  I'm a programmer trying to fill a big hole in my understanding of networking basics. I've been reading a good book (Networking Bible by Sosinki) but I have been finding that there is a lot of "assumed" information contained, where terms/concepts are thrown at the reader without a proper introduction to them. I understand that a "route" is a path through a network. But I am struggling with visualizing some routing-based concepts. Namely: How do routes actually manifest themselves in the hardware? Are they just a list of IP addresses that get computed at the network layer, and then executed by the transport? What kind of data exists in a so-caleld routing table? Is a routing-table just the mechanism for holding these lists of IP address (read above)? What are the performance pros/cons for having a static route, as opposed to a dynamic route?

• Win 7: Share internet connection via Ethernet and WiFi

  - by Anvaka

  I have the following configuration: Box 1. Running Win 7, connected to the internet via Eth0. Has one wireless network adapter and one more ethernet adapter (say, Eth1). Box 2. Running Win XP, has one ethernet adapter. I'd like to share Internet connection of the Box 1 with Box 2 via cable and have box 1 also sharing the Internet with other wireless devices. I don't want to buy any additional hardware. Is it possible? PS: Sorry if I'm unclear. I merely know nothing about NAT and network administration

• XP Mode under Win 7 Professional: Windows Activation Update failure despite activated Windows

  - by Cristina

  I am trying to install Windows XP Mode from here: http://www.microsoft.com/windows/virtual-pc/download.aspx (the Hardware-Assisted Virtualization Detection Tool has given me the green for proceeding) Even though my Windows has been activated a year or so ago, the download button leads me to a splash screen saying "Windows validation required". I am next forced to download a WindowsActivationUpdate.exe which, after downloading some mysterious "update", fails with the error message "Update installation failed, error information 0x80070002" (rough translation from German). I've tried running it both normally and as Administrator. What could be the problem?

• ATI Radeon HD 5970 Display numbering issues

  - by Arindam Sen

  I have 2 computers on which i have ATI Radeon HD 5970 graphics card installed. There is 1 VGA out and 1 DVI out in it. When I connect my VGA out to a monitor on my 1st computer, it shows it as display 1 and when I connect my DVI out to a monitor it show it as display 2 (I am using extended display). When I do the same thing on my 2nd computer it shows just the opposite. The VGA out shows as display 2 and the DVI out shows as display 1. Is it a problem with the drivers or the hardware? (because the graphics card on both is exactly the same)

• What would you use to keep track of all the random information about your LAN/Enviroment?

  - by agnul

  Say you work in your average anarchy... no appointed IT guy, no Office-Manager whatsoever, just developers working in free-for-all mode and a couple of non technical people around for admin (non IT) stuff. What would you use to keep track of Hardware / Software inventory Backups of OS images, Drivers, and all that LAN configuration information Passwords for all the systems Currently I'm thinking of having some sort of wiki + web server on our only ''server-class'' machine, but then I fear I'd be the only one who would go through the hassle of adding information in the wiki... So, have you been through that? What would you suggest?

• mirroring linux server to external usb harddrive

  - by DuPie

  My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

• PC wont boot with more than 1 stick of RAM.

  - by Aidan

  Hi Guys, I've got the following computer and I've just put in a new CPU QX9650 and I've run into this problem since making this hardware change. Whenever I put more than 1 of my 4 sticks of ram into my machine it wont load an OS. It'll go through the BIOS but BSOD on windows load. It also wont let me install an OS from disk or boot into Linux. I've ran memtest with all 4 sticks in and I get 10k+ errors on test5. Each stick of ram on it's own is fine and functions properly. I only have problems when all 4 sticks are in the machine at the same time. System specs.. CPU: QX9650 Mobo: Asus P5B 2104 BIOS RAM: 2xPC25400 DDR2 , 2xPC2 6400 both OCZ. Is the problem on my end or is the CPU faulty?

• Large file copy from NFS to local disk performance drop

  - by Bernhard

  I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler). I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit. At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes. Any ideas what could be causing this?

• Which one is better deal: iPed or Apple iPad?

  - by Evan Carroll

  The Chinese knockoff iPed is now in the wild and receiving a lot of attention? Does anyone know how the Android distribution it ships with compares with Apple iPad's software pack? How does the look-and-feel of the iPed fit with the Apple iPad? Quite frankly, I have little interest in Apple products because of the company policy. But, cheaper comparable hardware running open-source software is pretty interesting... Anything useful to add.. Here are the Apple iPad specs for comparison. The iPed is priced at $199.00, the Apple iPad starts at $499.00 .

• How to solve my black screen at boot?

  - by Juanillo

  I've got a friend with a weird problem. When he starts his computer the screen is completely black until the computer is completely started. So the screen is black until it suddenly shows the Windows desktop. He said that this is happening since a technical service repaired his computer, but that repair is not now in warranty. Recently the computer stopped working, but as the screen is black he cannot access to BIOS or start in safe mode (by pressing F8). When he inserts the Windows Vista DVD the system doesn't boot from DVD (it mustn't be configured in this way in the BIOS). Maybe there´s a problem with the hardware (maybe the graphic card)? Can anyone explain a reason why the screen is black during start-up? Any idea of what to do with the computer to restore it?

• emacs and putty on windows 7

  - by twilbrand

  My workstation was recently updated to Windows 7. I've downloaded putty and have configured it to the same settings I had under Vista. Whenever I ssh to a vm running Centos 5.4 and try to run emacs on a file, I'm getting an error about a connection to an X server: [ecto1 ~]$ emacs foo.bar Connection lost to X server `localhost:10.0' I never received this error message when I had Vista. I can get around it by aliasing emacs to 'emacs -nw', but I don't feel that I should have to do this. My co-worker has the same hardware that had the same upgrade and his sessions do not seem to be doing this. Any advice? I can't find anything on google and don't know where else to start. [ecto1 ~]$ emacs -version GNU Emacs 21.4.1

• Speeding up Connection Between Computer and Wireless/Bridged Router

  - by Justian Meyer

  Hey everyone, I looked through other questions, but didn't find useful responses. Our main computer has a dl speed of 6 Mbps, but some of our other computers are getting only 40-200 Kb! The router is wireless, but all computers are connected using a Netgear Wall-Plugged Bridge XE102, which transmits information via the building's powerline. It can't be the hardware itself, however, because some computers still manage decent speeds. The computers afflicted are running on Microsoft XP Service Packs 2 and 3, but so are computers that are totally functional. These speeds severely impede on productivity and are excruciatingly frustrating when trying to cram in time in the early hours. Could it be an issue with the computer? Location? Router? Many thanks in advance, Justian

• How can I to take an HDMI TV broadcast and overlay text in real time?

  - by ObligatoryMoniker

  Our company wants to be able to have LCD TVs displaying TV with the ability to add an overlay, like a stock ticker at the bottom of the screen, where human resources can add content to be displayed. I have been trying to nail down the correct terminology for this and come across terms like Keying, Compositing, Live Broadcast Graphics Presentation, and Hardware Overlay but I don't know which of these terms is truly the correct way to refer to what I am trying to do. Black Magic offers a product that seems like it can do what I am looking for but their product seems like it is geared for a totally different purpose than what I would be using it for. Compix also seems to have a product that would do what I need but again it seems like killing a fly with a sledge hammer. How can I to take an HDMI TV broadcast and overlay arbitrary content in real time?

• System time wrong after running ntpdate because DST ignored

  - by Ian Dunn

  When I run ntpdate, my system clock displays the time as an hour behind what it should be. I know that ntpdate does everything in UTC, so I'm guessing there's a timezone setting wrong and it's ignoring Daylight Savings Time, but I can't figure it out. Here's what I've done so far: ln -sf /usr/share/zoneinfo/EST /etc/localtime to set the timezone Set UTC=true in /etc/sysconfig/clock so that DST will be automatically applied date -s hh:mm::ss to set system clock correctly hwclock -systohc --utc to set the hardware clock correctly At this point date and hwclock both display the correct time. But if I then run ntpdate 0.us.pool.ntp.org, the date output is an hour behind what it should be. I've looked at a dozen tutorials and can't figure out what I'm doing wrong. Does anyone have any ideas?

• Should I quit using Ifconfig?

  - by Zhen

  With the servers that mount Infiniband cards, when I use the ifconfig command I have the warning: Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes. Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly. Ifconfig is obsolete! For replacement check ip. Should I quit using ifconfig? It is deprecated in favor of ip command? Or it will be update in the near future.

• Will disabling NAT on my wireless router cause a performance hit on my DSL router?

  - by user117313

  I have a Thomson TG508v2 router/modem and a brand new AirPort Extreme connected to it. At first, I set the AirPort Extreme to "share a public IP", which enables DHCP/NAT. Everything works great but I was having the Double NAT error. So I set the AirPort Extreme as bridge mode, which disables DHCP/NAT and let my crappy modem handle my internal network IPs. Will this cause any performance hit in my network? I'm worried because I'll outsource this job from AirPort Extreme (premium hardware) to the crappy modem. Before you suggest, I tried setting my modem as a bridge and configuring PPPoE on the AirPort Extreme, however it wouldn't connect to the internet, so I just dismissed leaving the modem as bridge.

• erratic audio levels on windows vista

  - by old retired dude

  I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

• How long do servers usually last?

  - by AX1

  I'm trying to estimate ROI for a new server and how long it will most likely be in service. Are there any average numbers for how long you can expect a server to last that's in 24/7 use? In other words, is it likely to find 10-year old server from 2010 in today's racks? How about servers from 2005? I'd love to get an idea for how long a server will most likely be in use. By the way, this is meant irrespective of growing or changing application needs. I'm talking only about the hardware.

• How do I SCP/FTP to a Coraid SR2421

  - by Pitto

  I need to save data to a Coraid SR2421. I am no expert and I'm trying to understand how this costy piece of hardware works. All I have is a Ethernet cable connecting my laptop and the coraid to a switch and the coraid's console with cursor blinking. Any kind of help would be greatly appreciated. edit and further explanation: I've tried using software on the coraid website but It's not working. So I've contacted the support and they sent me a file to upload on the coraid. It looks like if I upgrade coraid's firmware then I'll be able to use the coraid software on the windows side. That's why I'd need SCP/FTP or any kind of solution to copy a file in the partition that can be read from coraid console command line so I can launch the update command as requested. I hope I was a bit clearer now.

• Color Calibrate Dual Monitor XP SP2

  - by Laramie

  This topic has been touched on before but not really answered. I have a dual monitor system and the colors differ wildly. I currently live Buenos Aires where color correction hardware costs premium prices. I do some graphic design, but don't require a pro-level calibration. That said, I'd like my monitors to be set as close to "true color" as possible. I've located the useful and free Monitor Calibration Wizard, but it seems to adjust the entire system internally at startup. I could use the Microsoft Color Control Panel Applet to set a different ICC or ICM profile for each monitor, but the Monitor Calibration Wizard outputs its own format for profiles.

• What would happen if I did a "Boot to VHD" to a VHD that was configured to run under Hyper-V?

  - by tbone

  Microsoft has a Hyper-V based VM I'm interested in running, however, I don't have access to a Windows Server 2008 machine to try it on, only a Windows 7 Pro x64 machine (Windows 7 does not support Hyper-V). This is the VM in question: This download contains three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1) http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 I came across a somewhat relevant article from Scott Hanselman: Less Virtual, More Machine - Windows 7 and the magic of Boot to VHD: http://www.hanselman.com/blog/LessVirtualMoreMachineWindows7AndTheMagicOfBootToVHD.aspx I realize other options are to convert this VM to a VMWare compatible VM or some of the options to run it under VirtualBox. But instead of those routes, I'm wondering: What would happen if I tried to go the "Boot to VHD" route using this Hyper-V VHD? Is it possible that during the boot process, Windows would simply notice that hardware had changed and adjust accordingly, installing the appropriate drivers and continuing on without a hitch?

• Having Troubles Getting My Apache Server Online(NodeJS and Apache)

  - by Jeff Armingol

  I am new here. This is my situation. I am using nodejs modules, serialport2 and socket.io, because I am trying to forward the data from my arduino hardware through serialports. In my server side script, I read the data then forward it to the client side. Now I am using Apache to serve the html page,which is the client side. I am running Nodejs on port 8000 and Apache on port 80. It is running OKAY when I view it in my browser typing localhost:80. The data is appearing and seems fine. Now when I tried to get my Apache server online using a Free DDNS provider(http://www.noip.com/) and my port80, it loaded the webpage but there are no data appearing on the page. What seems to be the problem here? Really need your expertise and advice. Thanks in advanced!
