  • Share a USB sound card over a network/bluetooth (Mac & PC)

    - by AlexW
    I've been wondering how I can stream audio to an external Edirol USB sound card, wirelessly, on both Mac and PC. I'm not looking for high quality transmission, just to play mp3s from my Mac laptop to a USB sound card that is attached to two very nice balanced studio reference monitors. Is there any way I can firstly power the sound card box, and secondly, provide with an audio stream along it's USB input. I've looked at the Belkin USB hub, and I have a Time Capsule with the AirPort interface inside. These things seem to do vaguely what I want but when it comes to audio, the specifications are less clear. Any suggestions very welcome.

  • Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

    - by ultrasawblade
    I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

  • Installing Windows 7 from USB on a Thinkpad T61

    - by Halik
    I am trying to install Windows 7 Professional from USB 3.0 flashdrive, on a Thinkpad T61. The problem is, Thinkpads BIOS will not detect the flash drive as bootable medium, and won't allow to boot from it. What I did: Enabled USB BIOS Support in BIOS (it was on by default) In startup menu, added USB HDD to boot order (it has '-' sign in front of it) Created Windows 7 install media with UNetbootin, WinUSB (linux tool) dd and Grub4DOS. As you can tell, currently, I only have access to Linux machine to make the flashdrive. What happens: The T61 BIOS shows '-USB HDD' in boot order menu. The '-' sign suggests that the plugged flash drive is currently not bootable. The same flashdrive (with the same Windows image on it) is booting without any problems on a Dell D430 and Lenovo Y550. Also, Ubuntu 12.04 install USB created with Unetbootin shows as bootable ('+' sign in BIOS boot order menu) and boots from the F12 boot menu. Additional info thinkwiki.org says that some Thinkpad BIOSes do not use MBR on flashdrives. It suggests using Extended-IPL boot loader, but the provided links are broken and there seems to be no mirrors. Solution: http://superuser.com/a/430186/54970

  • Is it a good idea to have the operating system on a solid state drive?

    - by Kenji Kina
    There is something I don't quite understand. I know a SSD helps with OS load times, but I'm not sure if all this boost is only noticeable/interesting when booting, or gives an all around considerably better experience thereafter. I am interested in having a quick and responsive environment after booting, which leads me to think that it'd be better to spend the SSD capacity in my most used apps (and the page file? Another inside question) and not the OS itself. This, of course, means that I don't know just how much the OS reads/writes its files during normal usage. So, how good an idea is it to dump the whole 20GB+ of Windows 7 OS into the SSD (considering the hefty price per GB of SSD capacity) if I can put up with the usual hard disk boot times? Would I be missing on a lot if I didn't?

  • How do I set up a shared directory on Linux?

    - by JR Lawhorne
    I have a linux server I want to use to share files between users in my company. Users will access the machine with sftp or secure shell. Here is what I have: cd /home ls -l drwxrwsr-x 5 userA staff 4096 Jul 22 15:00 shared (other listings omitted) I want all users in the staff group to be able to create, modify, delete any file and/or directory in the shared folder. I don't want anyone else to have access to the folder at all. I have: Added the users to the staff group by modifying /etc/group and running grpconv to update /etc/gshadow Run chown -R userA.staff /home/shared Run chmod -R 2775 /home/shared Now, users in the staff group can create new files but they aren't allowed to open the existing files in the directory for edit. I suspect this is due to the primary group id associated with each user which is still set to be the group created when the user was created. So, the PGID of user 'userA' is 'userA'. I'd rather not change the primary group of the users to 'staff' if I can help it but if it is the easiest option, I would consider it. And, a variation on a theme, I'd like to do this same thing with another directory but also allow the apache user to read files in the directory and serve them. What's the best way to set this up?

  • Make a file non-deletable in USB

    - by MegaNairda
    Somebody used my USB drive and upon returning it to me, I found a autorun.inf that is undeletable. I tried changing it's file attribute which is only H (not even set as a system file) but it keeps on saying Access Denied. The USB is set on FAT32, upon asking my friend, he told me that he uses Panda USB Vaccine http://research.pandasecurity.com/Panda-USB-and-AutoRun-Vaccine/ How do they do this? Im trying to use some Disk Sector editor but have no idea which hex file they change to make this kind of file and make it deletable again. Formatting the drive removes it, but I'm curious as to how to be able to set those kind of file attribute.

  • Can I enable discards on a LUKS-encrypted ssd drive in RHEL6 (and do I need to)?

    - by Dan Nestor
    I have a RHEL 6.4 workstation, running on a LUKS-encrypted LV residing on a SSD. I found RedHat documentation stating that dm_crypt does not currently support TRIM passthrough, however I also found other sources that state the opposite (albeit for other distributions) and even that discards are not needed for recent SSD drives which use some sort of automatic garbage collection. So: 1) Can I enable TRIM/discards with my setup? 2) Do I need to, for optimal disk performance? Thanks for your thoughts.

  • Can Airport Extremes handle NTFS external drives?

    - by Electrons_Ahoy
    I've got an Airport Extreme and an external USB Hard Drive formatted with NTFS. (And a LAN of Windows XP Machines.) The drive works perfectly when connected directly to a PC. When it's connected to the AE, however, the Airport Utility sees the drive and lists it in the Disks list, but the drive doesn't appear on the network (as near as I can tell.) Can the AE handle NTFS formatted disks? The documentation is vague on that point.

  • How to re-add a RAID-10 failed drive on Ubuntu?

  • 2.5" SSD in a 3.5" desktop drive bay normal?

    - by Cory Petosky
    I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

  • Connecting a USB laptop to a RJ45 serial port

    - by Jon
    We are about to get our first managed switch at work (Procurve 2520G-24-PoE), and this lowly programmer gets to put on his admin hat and try to configure it. The switch has an RJ45 serial port for console access. My laptop has USB ports but no serial port. In fact, there isn't a single computer in the office with a serial port. I've seen USB-to-DB9 adapters, but I need to go from USB to RJ45 (serial). How would I go about accomplishing this? Do I need two adapters? Will USB-to-DB9 and then DB9-to-RJ45 work? Thanks in advance.

  • Backup solution to backup terabytes and lots of static files on linux server?

    - by user28679
    Which backup tool or solution would you use to backup terabytes and lots of files on a production linux server ? Note that the files are all different and almost never modified, and usage is mostly adding files, so data volume is today 3TB growing all the time at around +15GB/day. Please do not reply rsync. Basic unix tools are not enough, rsync does not keep history, rdiff-backup miserably fails from time to time and screw the history. Moreover these are all file based backup, which put a lot of IOwait just to browse directories and query stat(). But i guess, except R1Soft CDP, there is no way around that. We tried R1Soft CDP backup, which is block level backup, and it proved good and efficient for all our other servers, but systematically fails on the server with 3 terabytes and gazillions of files. That is already more than 2 months that the engineers of R1Soft and datacenter are playing a hot ball game... and still no backup except regular rsync We never tried big commercial solutions, except R1Soft CDP since it was provided as an optional service by the datacented hosting our servers.

  • Is there any way to force my Linux box to always boot up with a self-assigned IP address?

    - by Jeremy Friesner
    This is perhaps an unusual request: I'm trying to get a Debian Linux box to always give itself a self-assigned IP address (i.e. 169.254.x.y) on boot. In particular, I want it to do that even when there is a DHCP server present on the LAN. That is, it should not request an IP address from the DHCP server. From what I can see in the "man interfaces" text, there is an option for "manual", and an option for "dhcp". Manual assignment won't do, since I need multiple boxes to work on the same LAN without requiring any manual configuration... and "dhcp" does what I want, but only if there is no DHCP server on the LAN. (A requirement is that the functionality of these boxes should not be affected by the presence or absence of a DHCP server). Is there a trick that I can use to get this behavior? EDIT: By "no manual configuration", I mean that I should be able to take this box (headless) to any LAN anywhere, plug in the Ethernet cable, and have it do its thing. I shouldn't have to ssh to the box and edit files to get it working each time it is moved to a different LAN.

  • Tools required for a Web Development Project..

    - by RBA
    Hi, I wanted to design a project in linux which could contain programming languages(C, perl, PHP, HTML, XML etc) basically a web based project. Why i have chosen to build on Linux is because it is Open Source, and lot many things can be automated through scripting languages, which in windows i don't know. So, i have installed linux on a virtual machine(Host-Windows 2007 & Guest Linux CentOS), CentOS(command line interface). Since i am a beginner, so I want to know what all tools can be used to facilitate and ease my development process. Some which i know are listed below, and request you to please share your experience on this. 1) Using Putty so that can access the Linux machine from anywhere within the network. 2) Since i want to develop on Linux, but want to use windows as developing platform. So have downloaded Eclipse Editor (C/PHP) on windows. But want to know how can i access linux files from here?? 3) Installed Samba, and still trying to figure out how can i access linux files remotely on Windows. 4) Please share your experience, as how can i ease my development process. and what all tools i can use..?? Please let me know if you need any other clarification..

  • Linux Software RAID1 Rebuild Completes, but after reboot, its degraded again

    - by zimmy6996
    I have been beating my head with an issue here, and I'm now turning to the internet for help. I have a system running Mandrake Linux, with the following configuration: /dev/hda - This is a IDE drive. Has some partitions on it that boot the system and make up most of the file system. /dev/sda - This is drive 1 of 2 for a software raid /dev/md0 /dev/sdb - This is drive 2 of 2 for a software raid /dev/md0 md0 gets mounted but fstab as /data-storage, so it is not critical to the systems ability to boot. We can comment it out of fstab, and the system works just fine either way. The problem is, we have a failed sdb drive. So I shut the box down, and have pulled the failed disk and installed a new disk. When the system boots up, /proc/mdstat shows only sda as part of the raid. I then run the various command to rebuild the RAID to /dev/sdb. Everything rebuilds correctly, and upon completion, you look at /proc/mdstat and it shows 2 drives sda1(0) and sdb1(1). Everything looks great. Then you reboot the box ... UGH!!! Once rebooted, sdb is missing again from the RAID. It is like the rebuild never happened. I can walk through the commands to rebuild it again, and it will work, but again, after reboot, the box seems to make sdb just vanish! The real odd thing is, if after reboot, I pull sda out of the box, and try to get the system to load with the rebuilt sdb drive in the system, and when I do, the system actually throws and error just after grub, and says something about drive error, and the system has to shut down. Thoughts??? I'm starting to wonder if grub has something to do with this mess. That the drive isn't being setup within grub to be visible at boot? This RAID array isn't necessary for the system to boot, but when the replacement drive is in there, without SDA it won't boot system, so it makes me believe there is something to that. On top of that, there just seems to be something wonky here the drive falling off of RAID after reboot. I've hit the point of pounding my head on the keyboard. Any help would be greatly appreciated!!!

  • Backup files from Linux client to Windows Server

    - by Andrew
    I'm trying to backup my files from my Linux box to my Windows Server 2008 as a push, and when I delete them from my Linux box, they remain on my Windows Server. I've found lots of sources that are similar, but most results were from Windows to Linux. I managed to find slightly more similar cases like Using rsync and cygwin to Sync Files from a Linux Server to a Windows Notebook PC, and rsync from Windows PC to remote Linux server, with the most similar being a backup from Linux to Windows Server, but through a pull from the Windows Server. Initially, I used Unison because I thought having the 2-way capability would come in handy, and I would just have to set some configurations to make it 1-way. Unfortunately, I couldn't find the right configuration, and only managed to synchronize using the command unison "profile" -ui text -auto -silent. When I deleted the files on my Linux box, the files in the Server got deleted too, which of course, isn't what I want. When I tried to find any options for Unison, I only discovered the -force option, which didn't help, since what I wanted was an incremental update to the Server. I found out I could achieve this from using rsync and the -a option (archive), which would keep adding files even if I deleted them from my Linux box. I installed Cygwin on my Windows Server, configured an SSH daemon, but I can't seem to get it working. I've also already configured Windows Firewall to open port 22 (both inbound and outbound). I used the following command from my Linux box: rsync -avrzn /folder/to/be/backed/up/ [email protected]:/cygdrive/c/place/to/store/backed/up/files (a - archive, v - verbose, r - recurse into subdirectories, z - compress, n - dryrun) but it just won't work. Can anyone help me out? I don't mind using either Unison or rsync, as long as it achieves what I want.

  • Second HDD not seen by Windows 7 on Dell Xps l501x

    - by George
    I have a Dell XPS Laptop (l501x). I have replaced the original Seagate 500GB hard drive with an SSD Intel 320 120GB when I first purchased it a year ago. It's been working great. The laptop is booting in about 23 seconds, so the SSD is great. I have an Acronis image created that I came back to every three months just to keep everything clean. The SSD is partitioned with one logical drive for my data. So, recently I thought since I am not using my optical drive often enough to swap it out with a HDD caddy and add my seagate 500gb hard drive. I ordered the caddy placed the HDD in it and now load Windows. It just hangs on the screen that should show the Windows logo. I have tried everything that I know and searched it online. I have uninstalled the SATA controller AHCI and let Windows install it. Still will not boot into windows. I wanted to mention that the Seagate 500GB drive was the one that came with my laptop before I switched to the Intel SSD. As you know Intel has this application called Intel Rapid Technology which loads once in a while and shows the second hard drive, but then, when I restart it hangs again and Windows will not load. As soon as I remove the HDD Caddy and restart it loads Windows fine. I also formated the Seagate 500GB HDD in NTFS and still Windows will not load. When I go into the BIOS it shows the Fixed SSD and also "Sata ODD 500GB" instead of the optical drive but it will not boot into Windows when the HDD caddy is present. There is nothing wrong with the caddy. I have another laptop (Asus) and I installed the HDD caddy and Windows 7 loads without any glitch. I don't get it. I have also flashed the BIOS because Dell had a new version (A08). I also wanted to add that I refreshed Disk Management and the Device Manager and the second drive does not display. At this point I think it's a Windows issue so before I reinstall Windows 7 Home Premium from scratch I wanted to see if there was anything I was missing. Any advice would be greatly appreciated.

  • USB keyboard not working under Windows 7 x64?

    - by Comboo
    I have two USB keyboards, one no-name cheap thing and an old Logitech. When I plug them in to my computer they pop up in Device Manager as an "Unknown device" and "USB-receiver", respectively. Both of them fail to install any drivers, neither automatically or through Windows Update. Both keyboards work perfectly on another computer I have with Windows Vista 32-bit. Can this be one of those cases where a device does not work in a 64-bit version of Windows? I doubt it though since I've never had that problem before with any device and I thought that basic things like keyboards would be kind of failsafe. I don't really know how to start debugging this issue. I've tried all the obvious, rebooting, changing the USB port, etc. Are there any generic x64 keyboard drivers you can use? Is there any way to find the manufacturer of the keyboard over USB? There is nothing written on it.
