• Can you suggest some DIY PC specs for 1) Value, and 2) Future 'upgradability'?

  - by user17381

  Hi, I'm considering building a new desktop PC from components. For the last 7/8 or so years I have almost exlusively used laptops, and so have fallen behind a bit with knowledge of various hardware technologies. Anyway, now I'm considering building a new desktop machine. Mainly for development work, but also would be nice to do a bit of gaming. The two main criteria are: I would like the first build to be relatively low cost. I would like to select components that will allow me to upgrade in the future without throwing too much away. Can anyone recommend a setup? Thanks

• Network Interface Lost Functionality after Firewall Installation Hung

  - by Sadeq Dousti

  I tried to install Agnitum Outpost firewall, but the setup hung while installing network drivers. Oddly, the NIC properties shows no connect string whatsoever, nor any services: http://pic-ups.com/images/1fjf.png Device Manager shows problematic drivers as well: www.pic-ups.com/images/2aqa.png Any suggestions? PS: I'm using Windows XP SP3. PS2: I applied instructions below, but all were in vein: www.agnitum.com/support/kb/article.php?id=1000041 www.agnitum.com/support/kb/article.php?id=1000159

• PC is randomly shutting off

  - by Bobby

  I have a PC which is randomly shutting off (the hard way, like someone pulled the plug). It's no heat problem, because this can happen after 2 minutes of operation or after 4 hours and I checked the temperature. It's also no problem of the operation system, because it will also do that while in BIOS. If it happens once, you can be sure that it will happen within the next hour another two or three times, and then it works again for over a week or even longer. Possible causes I've thought about so far are: Voltage Fluctuation Loose contact (already replugged all cables within the PC, no luck) Faulty PSU Maybe someone has more ideas to this? P.s.: I don't have the hardware specs with me right now, I'll post them as soon as I get them.

• SCSI driver installation trouble

  - by Vicky

  I tried to install the driver of Adaptec 39320A-Ultra 320 SCSI card in Win2003 Server R2 SP2 in a DELL PowerEdge 2950 Server. I selected the driver from the list of drivers present in windows. But it says that the device could not be started(Code 10). I tried to put the card in a system that already had the driver installed. It worked fine. So there is no problem with the hardware. I even tried downloading the driver from the manufacturer website. When I try to select install from path and install that driver, it tell no matching driver found. When I install the default driver from windows, it shows the card in SCSI group of device manager, but with an ! symbol. Also the device ID in driver details was different from that of the one present in other system where it insalled fine. Any suggessions to solve it?

• My WD passport detected but not shown on my computer

  - by Rakesh Patel

  1TB WD harddisk is detected in laptop but drives not visible on my computer. Under disk managment drives shown without letters. Right clicking on these drives give 2 options: Delete volume Help. The same harddisk was running well on the same laptop a day before. It is also showing full size of hard drives, Healthy (Primary Partition) etc. (this happened after harddisk usage by guest). Harddisk is new only (about 5 month usage) Please suggest: Is there hardware related problem inside harddisk, if so is it repairable? Is there any option to recover data?

• Network Server Cabinets - How does the ventilation work?

  - by Nicholas

  Recently I've been looking at a range of network server cabinets with a mesh door at the rear. At the top of the cabinet are ceiling mounted fans with dust filters attached. These fans suck air out of the cabinet - presumably to remove the hot air that has risen to the top. My question is why do these fans have dust filters? What point do they serve? If the air flow is pulled in by these fans through the mesh door, then surely they are not there to protect the hardware inside from dust? Also, there are other minor grilled gaps around the enclosure, how does this kind of ventilation design work?

• Unable to create a Windows 7 system image of a failing hard drive

  - by Rahul

  The hard disk of my one year old T400 Thinkpad has started failing periodic hardware tests. I get a "Targeted Read Test Failed" error. The "SMART short self test" times out. I am now trying to create a Windows 7 System image of the hard disk but it fails without giving any specific error messages. I tried using Comodo Backup but got an error (code 101117) there as well. I have copied the important files in Dropbox but would like to take a full System backup as I have plenty of software installed on the machine. Does anyone know why this is happening and how I can take a backup of the system image ?

• How OS comunicates with HW?

  - by Jack

  Hi, how can program runnig on CPU (mostly OS) acess other PC hardware? Such as Graphic card, HDD and so? From what I read, In DOS, this was done using BIOS calls, specifically INT instruction. But, int instruction should only jump to the certain space in RAM. So, how can some program stored in RAM acess other computer HW, when CPU can acess only RAM, and reeive interrupts? And, does windows use int instructions as well, or is there any new way to communicate with HW? Thanks.

• Windows Advanced Firewall (Command Line Interface)

  - by Bradford Fisher

  I'm wondering where to find detailed information regarding the Microsoft Advanced Windows Firewall command line settings. For instance, from reading a couple technet articles I've learned that I can run the following: netsh advfirewall firewall set rule group=”File and Printer Sharing” new enable=Yes The bit about 'group="File and Printer Sharing"' is the part I'm having trouble finding documentation for. Any help would be greatly appreciated. And, if possible, I'd rather a pointer to the docs than a simple listing of group names.

Because of this, I am using virtual network interfaces like this: auto intern iface intern inet static address ... netmask ... gateway ...U auto intern:1 iface intern:1 inet static address ... netmask ... gateway ... I need to specify which IP should be used by default for outgoing traffic. How can I do that?

• Mac failing (failed?) hard drive - is all hope lost?

  - by Daniel

  It's a 500 GB Seagate laptop hard drive that came with my Macbook Pro. Apple partition format. Already replaced and now have it external, connected via SATA/USB adapter. Trying to get just a few files that I worked on while out of town when it crashed (and thus did not have my time machine backup drive). Drive will not mount, but OS X Disk Utility detects it and can read the capacity, model number, and even the name of the partition, which leads me to believe all hope may not be lost. Failed attempts so far: Disk Utility verify+repair says drive cannot be repaired and that I should back up immediately (lovely) Disk Warrior says it cannot rebuild the directory due to hardware failure Data Rescue quick & deep scans immediately failed PhotoRec says "error reading sector" for every sector (at least for the few minutes I let it run before closing it to explore other options) What else can I try here? Again, I'm just looking for a few, small files (python scripts to be specific) - not a full recovery.

• Is it dangerous to add/remove a hard-drive to a Windows machine which is in stand by?

  - by Adal

  Can I add a SATA drive to a Windows 7 machine which is in standby mode? The hardware supports hot-plug. Could pulling the drive out while in standby corrupt the data on the drive (unflushed caches, ...)? Does Windows flush before standing by? How about swapping a drive with another drive of different kind (SSD - mechanical disk) and size, also while in stand-by. Could the OS when waking up believe that the old drive is still there, and write to it and thus corrupt it, since the new one has different partitions and data?

• Windows XP freezes completely

  - by Max

  Lately my Win XP SP3 started to make problems. From time to time it freezes completely. Which means that the system does not react to mouse and keyboard. Keyboard led indicators also do not react to CAPS-, SCROLL-, NUM- LOCK keys. The problem is that I don't understand what causes this behavior and it seems to happen randomly. System event log also does not contain any clues. I'm thinking this could be some driver/hardware problem, but I don't know which. Are there any tools that would help me figure out the cause of this problem? Does anybody have any clue how can I fix this?

• How to make a quiet laptop ? [closed]

  - by psihodelia

  Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be pdf/docs processing, real-time audio processing, web-surfing and skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend me any solution please? Thanks in advance!

• Samba domain trust errors on a specific interface

  - by John K

  We have a windows domain that also has RHEL member servers in it. All the servers have a primary network connection to the LAN, but some servers also have private dedicated links to one of our RHEL servers, which serves as a head to our SAN storage. This particular server is running Samba 3.5.15, and is running in domain authentication mode. Users can access shares on this server without a problem over the LAN connection from our Windows servers, but if a user tries to access the shares over a private link (i.e. a 192.168.1.2 address to the RHEL server) users get an error "The trust relationship between this workstation and the primary domain failed."

• Looking for command line interface for setting Index properties for many files

  - by Sherryl

  I'm looking for a way to set a group of File Types to "Index Properties and File Contents" (Control Panel, Indexing Options, Advanced Options, File Types). Basically I'd like to write a batch file that switches that setting for a large group of file types and be able to share it with my entire team. Clicking in the UI is time consuming for everyone. This is a great solution for bringing up the GUI, but I'd like to create a batch file What is the command line for Indexing Options?

• Need recommendations for a hardy scanner that has a robust feeder tray

  - by JohnyD

  In the early days of our company all our information came in on paper and all of what we sold was on paper. Because of this we literally rent our an old bank vault to house the millions of sheets of paper that, some say, still contain relevant information. That being said, I'm looking into purchasing some hardware capable of scanning all these documents and converting them to pdf. Being new at this level of digitization I would like to ask for recommendations for accomplishing this task. Most of this material exists as separate bound studies/articles/etc. Someone would have to remove the bindings and be able to load many pages at a time and have the scanner feed them all through and convert them to a single pdf (single pdf per study/article/etc). If you have any recommendations I would very much appreciate hearing about them, thanks.

• Uncorrectable machine check

  - by GregC

  I am experiencing rare but real unrecoverable machine checks on HP DL370 G6 dual-core Xeon server. I ran memtest86+ before, and ran CPU-intensive operations without any problems. In your opinion, does this indicate a real problem, or is it normal and expected behavior? How would you approach this problem? EDIT after some troubleshooting, it seems that these machine checks, as well as problems when showing device manager can be traced back to NC375i NICs. All is well when the NICs are not in the server. Further improvements to stability of HP Gen6 with Intel Xeon have been brought in with BIOS update in September 2013 HP Update DVD. Intel's newer microcode makes these CPUs much more stable. We haven't seen hardware-related BSODs since the update in September.

• Linux Log Viewer with Web interface

  - by user180039

  I have been asked at work to find a solution to one of our problems. We have several logs that customers need access to, because we don't want to give them direct access to the folder/share we are looking to implement a simple Web based solution that permits customers to login see a list of files they have permissions to and download the file. It would need to be able to setup permissions so User01 can see file01 and file03 and User02 can see file04 and file06, optimally all the files would be under the same folder, so permissions are based on files rather then based on folders. Anyone got any ideas Many Thanks

• Use LAN to interface Synergy while having WiFi connected to internet

  - by freonix

  Similar question and solution I have LAN and WiFi connection, with the WiFi connected to internet and the LAN is simply connected via an Ethernet cable between two computers. I need to get Synergy working without compromising the WiFi internet. I've tried the solution above but couldn't seem to work. Both of the computer are running Windows XP. Even setting the LAN IP to static and under the same subnet doesn't seem to work. Anyone with similar situation and got Synergy to work? edit : Refined the question for clarity. Also, the computer are able to ping each other. Remote desktop can be accessed as well. I suspect the problem lies in Synergy's configuration.

• Wireless access through command line interface

  - by hfranco

  Is there a CLI command or program that will list available wireless access points? I'm running Ubuntu 9.04 on a laptop and sometimes I boot straight into the CLI instead of a GUI. I know iwconfig can configure a connection but will not list available AP's.

• Snort monitoring of spanning interface

  - by aHunter

  I have configured a Cisco 3500 switch with a port SPAN and have my snort node (fedora 13) plugged into it. I am running snort as a daemon and have configured a rule to log all tcp traffic but I am only seeing traffic with a destination of the snort node. I know that the SPAN port is working and wanted to know if there is a specific option that I needed to start snort with in order for it to pickup all the traffic? Or is there something that I have missed here? Many thanks.

• How to setup IP alias on bridged interface in Ubuntu

  - by Anonymouslemming

  How do I setup an IP alias on a bridge (br0) device on Ubuntu ? If I wait for br0 to come up and then do /sbin/ifconfig br0:0 192.168.10.1 netmask 255.255.255.0 then it works fine. If however I add the following to my /etc/network/interfaces file, it does not work and the network fails to start: auto br0:0 iface br0:0 inet static address 192.168.10.1 netmask 255.255.255.0 At the moment, I have a script in /etc/network/if-up.d/bridge_alias that does this as follows: #!/bin/bash if [ "${LOGICAL}" == "br0" ] && [ "${PHASE}" = "post-up" ]; then echo -n "Starting br0:0 ... " /sbin/ifconfig br0:0 192.168.10.2 netmask 255.255.255.0 echo "Done!" fi What is the right way of doing this though, just using the OS network config files ?

• Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

  - by iyl

  I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.
