• very slow bridge detection

  - by deddihp

  hello everyone, I have setup some bridge interface with 4 ethernet port. My problem is, when they detect some network topology change, the bridge really need a lot of time to have done it. Is there any solution, so the bridge can detect topology change faster ? thanks.

• Virtual PC, XP mode. Bidirectional parallel port physical LPT1 not available in VPC XP mode?

  - by Tom Merklin

  I need my LPT1 port to be available in XP mode. In the "guest" window, it shows up in system hardware, but it is not available to the application. If I look into Tools, settings there are no parallel port available? How can I fix this problem? (If I use VMWare Workstation XP mode, I load a driver and it works perfect).

• Ubuntu Keyboard response speed problem.

  - by Asaf

  Hello, I have Ubuntu Lucid Lynx installed, Using Gnome 2.30.0 I'm using a Laptop, HP Pavilion dv9000 I've stumbled on responsiveness issues with my keyboard, Sometimes it's really obvious - the keyboard doesn't respond fast enough to my typing. Checked sticky keys and all that, it's all disabled of course. Now, I also checked on Windows to see if the problem is Hardware or something, and there are no responsiveness issues there... I'm thinking it's Gnome (or the X). Thanks.

• Please recommend a USB wifi adapter for Ubuntu 9.10

  - by Jozxyqk

  I've read through the "supported hardware" pages for Ubuntu, but it's a long list, sorted by manufacturer, with lots of anecdotal evidence. All I am looking for is a USB wifi adapter that "just works" with Ubuntu. Any recommendations? Apologies if this question isn't phrased well.

• How do I configure Thunderbird to locally remap the label-folder in an G-Mail IMAP account?

  - by Edward Beach

  I'm using G-Mail and Thunderbird together for an imap account. One of the limitations of G-Mail is that there's no concept of nested labels - which is fine when I'm using the account through the web interface but when I'm using Thunderbird I would like a bit more organization. Is there a way for Thunderbird to locally remap an imap folder's path? For example with a "MyCustomLabel" label: Thunderbird: "MyAccount/path/on/local/machine/MyCustomLabel" G-Mail: "MyCustomLabel" Thanks

• What software/method can I use to make Matroska dump of DVD under Linux?

  - by depesz

  I have set of DVD disks. I'd like to rip them to .mkv files, but with all information - i.e. all subtitles, and all audio tracks. Is there any tool on Linux that I could use to do it? I found some Gentoo howto about ripping, but it requires writing shell scripts, and I'd rather use something with clickable interface.

• Open Google Reader links in background Safari tab?

  - by dbr

  When you press the v keyboard shortcut in Google Reader, it opens a new tab. Regardless of the setting "When a new tab or window is opened, make it active" setting (Under Preferences Tabs), it becomes the frontmost tab when opened. Is there a way to have all tabs open in the background, like when you Cmd+click? (I'm aware of other alternative solutions, such as Firefox which handles this correctly, or a desktop RSS such as NetNewsWire/Vienna which have an "open links in background" option, but I like Google Reader's interface and wish to continue using it)

• Bare-Metal Restores of Linux Servers with Tivoli

  - by Chad P

  We currently use IBM Tivoli to back up our Linux servers and we are looking for suggestions on the best way to restore to bare metal. I've read IBM's doc on this issue. Is that still relevant or is there a better way? Also, how do you handle testing a restore to a vm or another piece of hardware on the same network that the original server lives?

• Are FC and SAS DAS devices standard enough?

  - by user222182

  Before I ask my questions, here is some background info that may or may not be useful: For the first time I find myself needing a DAS solution. My priority is data through-put in a single direction. I can write large blocks, and I don't need to read at the same time. The server (the data producing device) is not really a typical server, its a very powerful single board computer. As such I have limited options when it comes to the add-in cards I can install since it must use the fairly uncommon interface, XMC. Currently I believe I am limited PCIex8 gen 1 which means that the likely bottle neck for me will be this 16gbps connection. XMC Boards I have found so far offer the following connections: a) Dual 10GBE ethernet controller, total throughput 20gbps b) Dual Quad SAS 2.0 Connectors (SFF-8XXX) HBA (no raid), total throughput 48 gbps c) Dual FC 8gb HBA (no raid), total throughput 16gbps My questions for you guys are: 1) Are SAS and/or FC, and by extension their HBAs, standard enough that I could purchase a Dell or Aberdeen storage server with a raid controller that has external SAS or FC ports and expect that I can connect it to my SAS or FC HBA, be presented with a single volume (if I so configured the storage server), all without having to check for HBA compatibility? 2) On a device like a Dell PowerVault (either DAS or NAS) is there an OS on it to concern myself with, or is it meant to be remotely managed? Is there a local interface in case I cant remotely manage it (i.e. if my single board computer uses an OS not supported by Dell OpenManage). Would this be true of nearly any device which calls itself a DAS? 3) If I purchase some sort of Supermicro storage chassis, installed a raid controller with external connections, is there a nice lightweight OS I can run just for management of the controller? Would I even need an OS since the raid card would be configured pre-boot anyway? 4) It is much easier to buy XMC based 10gigabit ethernet cards (generally dual port). In what ways would I be getting into trouble by using iSCSI as a DAS are direct cabling with SFP+ cables? Thanks in advance

• installing OpenCV 2.0 on Ubuntu Karmic: still get ImportError from "import cv" in Python

  - by kostmo

  I have tried compiling and installing from the 2.0.0 release source, the SVN head, and from a PPA. After each, I still get the following from a Python console: >>> import cv Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named cv Starting with the "new" Python interface in 2.0, that import is supposed to work.

• Unix Password Management Keyring

  - by Phil

  I am looking for a password manager for a command-line Unix environment. So far all I can find are keyring applications for Windows, Linux, and Mac. But no command-line Unix interfaces. My main goal is to be able to access a password keyring through an SSH connection to a machine that has no graphical user interface. If there are no good unix password keyrings out there, what would be a better way to store personal passwords in a central location?

• Mac OS on a Windows PC

  I've done a little bit of reading on the topic, but nothing too clear has turned up. Why is it so difficult to run Mac OS on a virtual machine on a PC? Some sources say it's because of hardware architecture. Is there a clear, definitive reason?

• Implications of using many USB web cameras

  - by Martin

  I'm looking into connecting multiple low resolution USB webcams to a single computer. What implications might this have on performance? How does, for example, four 320x240 cameras fare against a single 640x480 camera? I'm not well versed in the architecture of the USB interface, what are the performance caveats? By performance I mean how would it affect the time to read the image data from multiple cameras compared to a single one.

• Personal email server

  - by celil

  I would like to set up a personal email server. I am currently using Gmail, but I am becoming increasingly concerned at the amount of data that I share with Google. I would like to migrate all of my email to my personal server. Is there an easy to use, secure, open source alternative to Gmail that can be ran on personal servers? I do not need a web interface to my email as I usually access it via IMAP.

• Enterprise desktop antivirus without a Windows server

  - by Adam

  Are there any desktop antivirus products suitable for use in an enterprise environment without a Windows server? We're currently using McAfee for our Windows desktops but to get updates and alerts with the latest version it looks like you need to be running their EPO server software. I'd like to avoid the cost of hardware and Windows licensing, and if possible to run just client-based antivirus. Ideally it would support: Updates from an internal copy of the definitions (e.g. a wget mirror) Automated configuration of the install Alerts from the client via email

• Rapidshare download manager accessible over network

  - by Alexis Hirst

  Hi, Basically I am looking for a download manager, which I can run on my server to download rapidshare files, while also being able to access it over the network via a standalone client application or web interface on another machine. I use azsmrc for azureus, so something similar to this would be great. Any ideas?

• Gigabyte GA-970A-UD3 mobo won't boot from USB flash drive

  - by user38586

  I am trying to boot BAMT a Debian flavor via USB on a brand new Gigabyte GA-970A-UD3 motherboard. I tried various flash drive and various OS. I never had this problem with ASUS and MSI. The problem is from Gigabyte hardware. I found that my BIOS is very strict about MBR compatibility. Now I can boot in DOS mode. The flash drive need to be formated as a Win98 Startup disk using HP USB disk storage format tool. Unetbootin menu is booting from USB but won't install BAMT. If I use Windows or Linux diskimager the working MBR is deleted. I tried converting BAMT .img to .iso and it is not booting with Unetbootin. Is it possible to boot BAMT(Debian Linux) from a Win98 DOS command prompt? Maybe there is a way to burn the image and keep the working MBR? If the working MBR is deleted, the flash drive is not recognized at all by the BIOS. This is the info I found that got me booting for the first time in DOS: GB's BIOS will only boot USBs formatted to FAT-32, conforming to normal MBR bootloader. I've seen this before, and surmised that the 'stick-maker' was formatting in ReiserFile, or one of the EXT 'flavors', but no one ever followed up to confirm or deny... Also, if it's putting the bootloader into its own partition - won't work! In the BIOS, on the "Integrated Peripherals" page, the "USB Storage Function" item must be enabled (which should be the default) to allow USB booting... I've put a little work into a 'GB USB booting tutorial', and frankly, I'd just go ahead and finish it up for you, but I really don't want to reboot the several times it will take me to 'firm up' procedural details, and take the BIOS/boot pictures for the post - just noticed VAIL finally went 'public beta', so will be downloading for likely twenty-six hours or so There's likely enough there to test a 'raw DOS boot', just to see if your hardware (especially the USB stick itself) will do it... Some post later: Fixed. Here is a brief summary. Since my ubuntu live usb sticks (2gb kingston and 8gb sandisk sd/usb reader - fat32, created in ubuntu 10.04) would not boot this board even though they would boot my ga-ep45-ud3p, I decided to try bilbat's suggestion with the HP usb boot program. I created the win98 boot disk on the kingston 2gb stick without reformatting. It booted right up. Next, I used windows version of unetbootin to write the ubuntu live cd to the kingston disk. This fired right up and completed the install. Everything seems to be in good order now. Unfortunately I can boot in DOS mode but can't boot BAMT.

• Overhead video camera to capture live video to a PC

  - by BrianLy

  Can anyone recommend a manufacturer or starting point for overhead video camera units that can be used to capture a Microsoft Surface application in use? I'd like to stream this from another PC but I'm not sure what the best camera to look at would be. It seems like some of the overhead security cameras would fit the requirements but I don't know if they will interface easily with a PC.
