  • Unable to connect to shared (iscsitarget) dvd-rw drive on ubuntu karmic box

    - by develop7
    Preface: I have desktop with DVD-RW drive that runs primarily on Linux (namely Ubuntu 9.10). My wife has netbook that rins Windows XP with no cd/dvd drive. There's also LAN through our ADSL modem/router. I've "ported" (actually, I've just grabbed sources and ran dpkg-buildpackage) iscsitarget package from Ubuntu Lucid to Karmic (here are packages), installed it (sudo aptitude install iscsitarget; sudo m-a a-i iscsitarget) and configured it in the following way (/etc/ietd.conf): Target iqn.2020-01.local.develop7-desktop:storage.disc.dvdrw Lun 0 Path=/dev/sr0,Type=blockio #I've skipped commented lines Also, I've opened port 3260 with ufw: $ sudo ufw status | grep 3260 3260 ALLOW 192.168.1.0/24 But (here's the trouble) I still can't connect to this target from Windows box. Microsoft Software iSCSI Initiator tells "Logon failure" upon connect attempt. After unsuccessful connection attempt I've noticed this line in dmesg | tail's output: iscsi_trgt: ioctl(299) invalid ioctl cmd c078690d So the question is — what's wrong with my config/iSCSI target/whatever else? Or, in short — what I'm doing wrong? Thanks in advance.

  • Lock screen keeps making sound when screen is off

    - by row1
    I have my laptop (Asus UL20FT) on external power and hooked up to an external monitor. I keep the laptop lid closed and am using the 'second screen only' option. If you leave it on the lock screen for a short period of time the screen powers off. While the screen is off it keeps repeating a "duuuh duh duh" sound (sounds just like the device plugged in sound). The monitor is connected via HDMI and I have Microsoft and Logitech wireless USB dongles plugged in. How can I prevent this sound loop?

  • Nearest PC equivalent to Mac Target Disk Mode?

    - by username
    Mac firmware has a special boot mode that allows you to offer its internal hdd to another computer as an external disk (you just connect the two machines via an IEEE 1394 cable). Only the second machine needs a functioning OS installed. Any good suggestions for something similar on the PC side of things? Block level access isn't important to me, I'd just like to be able to copy files off it. It doesn't matter to me if it uses Ethernet, IEEE 1394, or wifi - I just like having a quick way to access files on a client PC. Is there any single-purpose Linux distro specially designed to do this? It'd be nice to have something super simple, quickbooting, and small that I could install on a USB drive. I used to use Knoppix, but it's overkill as a Target Mode replacement.

  • Opening port 80 in router has no results

    - by Ricardo Pieper
    A friend of mine has a ADSL modem and I need to forward some ports. I have already forwarded the 1521 port (Oracle) and it's working fine. Now I need to forward the port 80. I already set up his IIS bindings to this port, and also forwarded the port like this video shows: https://www.youtube.com/watch?v=DLKD-fyexoo So I think I did everything correctly. The local IP address is also the same as the machine where the IIS server is running. I'm sorry, but I can't post images since i don't have 10 points :( Somehow I can't forward this port, yougetsignal.com keeps saying that the door is closed. When I try to open the port, the Control Panel says me that I have to access the control panel in the 8080 port, because the 80 port will be open. Ok, that's fine. But I'm still able to access it in the 80 port, and when I try to access it in the 8080 port, it doesn't work. I'm trying it with the TPLINK 8816, but I also tried to open it in the Opticom DsLink 279, and it didn't worked (using another machine), I got the exact same results. He has a dynamic IP address, but he is also using No-ip, so I can always access his Oracle database in a certain static address. The 1521 port is open. I also tried to disable the firewall in Windows, but that makes no sense to me, since the router doesn't really open the port 80. Clearly I'm missing something. I have never done it in my life, so I dont know how to proceed. Restarting the router was the first I did, no results. I'm accessing his laptop through TeamViewer, so I'm testing the port outside his local network. Edit: My ISP says that they allow to open ports, and the 1521 port is opened. What could I do to open the 80 port?

  • Windows XP restore point file from disk.

    - by Dragos Toader
    Suppose I copied a Windows XP restore point file to a USB memory stick. I copied C:\System Volume Information\MountPointManagerRemoteDatabase C:\System Volume Information\tracking.log C:\System Volume Information\_restore{45B5E8B9-949A-471E-999D-F381DA56A2D3} C:\System Volume Information\catalog.wci to F:\System Volume Information\ How can I restore this restore point? Can I fool the system into using that file (if I copied it back into the restore point folder)? From F:\System Volume Information\MountPointManagerRemoteDatabase F:\System Volume Information\tracking.log F:\System Volume Information\_restore{45B5E8B9-949A-471E-999D-F381DA56A2D3} F:\System Volume Information\catalog.wci to C:\System Volume Information\

  • fast way to find network user computer on domain hogging all wan bandwidth

    - by dasko
    i have a network of about 40 domain users and i have huge latency wan issues, like 1400ms for google.com pings. I have noticed that the problem goes away after everyone goes home for the day. I would like to know if i should use something like a hub with wireshark on the router or modem to see if there are any irregular activity. I am open to suggestions but i need to isolate which user has the bug. I am assuming it is either downloads or someone spamming out heavily and not knowing. It would be best to trace to ip number so i can just look into dns and find the pc hostname with the problem? This is the first client i have this problem with so never really needed to address it before but not suprised as users don't actually listen to any best practices that we have suggested. Please help, thanks. just to update, pc's to routers and other computers have ping latency of 1ms so it is right after i hit the wan, using tracert to a web site (random), that i get the massive delay in the responses. As well this is a dsl line with 5mb down and 650kb up (maybe upload saturation?) thanks.

  • Why my 2nd ip from traceroute is not answering the ping anymore?

    - by Pedro77
    My Internet is really laggy today, I did a tracerout and I realize that I'm having no answer from an ip at the beginning of the traceroute. see: Tracing route to 12.129.202.154 over a maximum of 30 hops 1 <1 ms <1 ms <1 ms 192.168.0.1 2 * * * Request timed out. 3 8 ms 8 ms 8 ms bd044008.virtua.com.br [189.4.64.8] 4 9 ms 8 ms 8 ms bd044009.virtua.com.br [189.4.64.9] 5 26 ms 26 ms 24 ms embratel-T0-1-5-0-tacc01.cas.embratel.net.br [200.174.243.21] 6 360 ms 15 ms 12 ms ebt-T0-15-0-12-tcore01.ctamc.embratel.net.br [200.244.140.218] 7 330 ms 349 ms 261 ms ebt-Bundle-POS11942-intl04.mianap.embratel.net.br [200.230.220.10] 8 139 ms 141 ms 139 ms sl-st30-mia-.sprintlink.net [144.223.64.221] Connection diagram: PC - Router configured as access point - Router (192.168.0.1) - Cable modem (192.168.100.1). Well, I think it is odd that the 2nd ip is not returning the ping. I looked some old tracerout logs to see what was the 2nd ip. The ip was: 10.19.0.1 So, what this 2nd ip stand for? How can I find why it is not answering the ping? I don't understand it, if does not answer the ping, how can the packets continue (yeah newbie question)? edit: well, because the hope 3 have a ping of 8 ms the hop 2 request time out should really not be a problem. But it is still odd that the 2nd hop stopped to answer ping request. So my doubts are: 1. Were the ip 10.19.0.1 is from? 2. Why it stopped to answer ping requests? 3. How can hop 7 be smaller than 6 and 8 smaller than 7 and 6!?? Shouldn't the pings be higher for each hop? Like: hop 3 time should be the sum of the hops before it plus its own time (hop 3 = 1+2+3) ??

  • No GUI after upgrade to Ubuntu 9.10 (boots to command line)

    - by Gathris
    I have just upgraded to Ubuntu 9.10 (network upgrade using the update manager, from 9.04 which had different graphics related problems) and when I try to boot into it all I get a small Ubuntu logo, flickering text and then the tty1 command line with a logon prompt. startx gives following error: Fatal server error: no screens found I traced down a tutorial that said I needed the latest graphics drivers (Gigabyte ATI Radeon 4650 HD installed with 9.10 catalyst drivers) so I did using the 'sh' command and a USB stick (I have a working Windows partition) and it installed fine but did not fix the problem. Edit: Thanks to UK and Arjan van Bentem below I was able to understand the full error message of start x: Parse error on lone 2 of /etc/X11/xorg.conf 'nameserver' is not a valid keyword in this section Fatal server error: no screens found This has nothing to do with a graphical error (sorry if I misled anyone) but the xorg.conf file has 3 lines in it and lines 2-3 have an entry 'nameserver'. Using the nano command I commented out (using a # before the entries) the nameservers and can now boot Ubuntu. Thanks to everyone for their help.

  • Configuration for Router Behind Uverse 2Wire

    - by Nori
    I have a 2Wire Uverse router(RG). I'm not particularly fond of it and want to use it as a modem only. I have a Linksys router with Tomato firmware on it and want that to be configured as the router. Most of the "guides" I've seen in my searches has been to enable DMZ Plus mode, but I don't see a way to make that work while my router has a static IP address. I played with it for quite some time yesterday and didn't see a way to get it to work. Then I ran across a setting in broadband for configuring another network. I played with that for a little bit but ran out of time and couldn't get it to work. So my question is for anyone out there who has Uverse and successfully setup a Tomato based firmware router behind the RG. How did you get it configured? I'm sure if I continued playing with it I could get it to work, but if someone out there already has it working then that would make my life easier. Thoughts? Thanks.

  • Configuring Server with no monitor

    - by Scandalist
    Sitting in front of me is an HP DL 380 Generation 4 with no monitor. I'd like to install an OS on the thing but for reasons obvious, I can't. I got excited when I found the ILO port on the back but unless you have a subscription it has limited functionality. I was thinking maybe there was some software out there that booted into some kind of remote access server? When I tested it with a monitor (A friends) I set the BIOS to boot from USB so anything I can load onto a stick should boot. Ideas? Hacks?

  • Getting FC11 to run under VMware Server, converted from physical machine

    - by Kristian
    I have a FC11 installation that I have converted to a VMware disk image to run om my VMware Server. I converted it with qemu-img, as the VMware Converter software apparently only converts Linux hosts to VMware Infrastructure servers. The disk image boots fine (grub is loaded and boots the kernel) but it seems like the disk is not found by the kernel, and the boot process stalls. Hotplugging USB devices work (the kernel prints debug information) and I'm able to press keys (Ctrl-Alt-Delete for instance). The VMware guest OS is set to RedHat Enterprise Linux 5 (32 bit), and I have tried both the LSI Logic, LSI Logic SAS and VMware Accelerated SCSI SCSI controllers, to no avail. I'm able to boot an installer disk and get into rescue mode and mount the filesystem, so my question is, what do I need to do to the guest kernel / initrd image to make it recognize the virtual disk?

  • UPS recommendations for three grey boxes?

    - by Margaret
    Hey all We have a series of grey-box style computers acting as servers at my workplace (rather than rack-mount). We were looking to get Uninterruptible Power Supplies for them. However, I'm not sure how many at what capacity are required. I'd assume it would be a good idea to hook the peripherals in as well - there's a 18.5" LCD monitor with a KVM, along with a couple of USB hard drives that require power. I currently have the most vital machine hooked up to a cheap (temporary) UPS, but it's probably close to worse than nothing. I'm looking for reasonable value for money, though I can probably negotiate with my boss on price range. I recognise that I may well need to buy two (or even three) UPSs to support the three machines. Any recommendations?

  • Install mountain lion by using the .dmg from installer app

    - by Leonardo
    I already have a Mountain Lion Installer app, downloaded from Apple Store. Now, I would like to install ML on another machine I own. I didn't want to download it again, so I copied the .app to the other machine and try to run. Unfortunately due to some error about mac unable to run the .app I wasn't able to install. Most tutorial suggest to make a bootable USB starting by the installer InstallESD.dmg, found in installer .app. I would like instead to run the .dmg directly. So I have three 'propedeutic' questions: can I just mount and run the .dmg without making a bootable drive ? I do have backup, a TimeCapsule one to be precise. In case of failure, can I just use the previous backup, and restore to Lion 10.7 ? from 'Apple Store point of view', would my machine be recognized as upgraded and elegible for future update ?

  • Hooking up a laptop to an HDTV via VGA

    - by Redandwhite
    I have a 2-3 year old laptop running XBMC, and I have an HDTV that I'd like to connect it to. The only output that the laptop has is VGA (and S-Video - I don't know if the TV supports it) . The TV doesn't support VGA input, but takes HDMI. -- Is it worth buying a VGA-to-HDMI converter? As in this: -- Are there any other, cheaper options available? There's a lot of information around the WWW, but a lot of it's outdated and it's hard to digest everything. I know of at least one other option, and that's a USB to HDMI connection, but I don't even know what to look for or where to get started on that one. I also suspect it might be a little more complicated. If it's cheaper then it could be worth it. EDIT More Details: Intel integrated graphics card (Intel 945 Express Chipset Family) The TV supports up to 1080p resolution

  • Suspected Router problems, [closed]

    - by jordon_user
    I am new to this forum. I appreciate any help you can offer. I have been troubleshooting an error with both my WIRED Internet Connection I have 3 desktops running through this working connection (Router) with no problems. Two computers, one laptop and desktop experience the issue. If I connect directly to the Modem, on either, no problem on the internet. Through the Router, my computer connects for a period of time but if ever awaking my comp, or restarting, the yellow explanation mark returns. The only way I can get the connection up = cmd. ipconfig /release, ipconfig /renew. This constant command is annoying and was hoping for a permanent fix. Audio is also not working. I know its likely a driver error, but its an old comp we put together and if there's an easy fix itd be great to hear from you! If you need any more info just let me know. Thanks! THanks guys!

  • Java Swing over Remote Desktop - Strange, weird GUI squashing

    - by ADTC
    I thought this question fits SuperUser more than StackOverflow because it's not about actual Java programming, though programmers might be more likely to encounter the problem. Anyway, let me start of with some stats before I ask the actual question: Laptop: Windows 7 x32 Screen resolution 1024 x 768; Nvidia GeForce Go 6200 Connected to desktop via ad-hoc wireless network Access internet via desktop Desktop: Windows 7 x64 Screen resolution 1920 x 1080 Connected to laptop via ad-hoc wireless network Access internet via cable modem I'm connecting to my laptop via Remote Desktop from my desktop to take advantage of the large screen. I'm doing programming on my laptop (for portability reasons). Everything else runs smooth and fast over Remote Desktop as both computers are connected directly over the ad-hoc wireless. The only problem is this: Java Swing apps don't display the GUI properly. I acquired a Java Swing application and I'm debugging it in Eclipse. Here's what I got when I ran the app: Apparently there doesn't seem to be anything wrong with the GUI application I'm debugging, because the Java Control Panel exhibits the same problem. I've searched high and low in Google about this; the closest I came to a solution is this. But sadly, the use of -Dsun.java2d.nodraw=true has no effect at all. This only happens over Remote Desktop. I have tried locally and the GUI apps display properly. This isn't a dealbreaker for me as I can stop using Remote Desktop when developing Java Swing apps. However, I would like to know if anyone has encountered this and found any solution. PS: All software involved (Eclipse, Java JRE, etc.) are latest versions.

  • Driverpack Solution makes a whole bunch of programs

    - by Markasoftware
    I am using Driver Pack solution 12.3 to update my drivers. I used it and installed 55 drivers. I noticed that there are now several dozen new entries in add/remove programs under the name Windows Driver Package - Intel hdc, Windows Driver Package - Intel System, and Windows Driver Package - Intel USB with the driverpack solution logo next to them. When I hit uninstall for any of these, it says all devices using this driver will be removed, and I am scared of uninstalling anything I do not know about. I have no system restore points before I updated my driver. Will these extra driver packages slow down my computer or take up extra disk space? Can I uninstall them safely? I am using Windows 8, so refreshing the computer is an option.

  • How to backup in Fedora-13?

    - by Ramy
    I just bought a 1.5T HDD and a disk enclosure. I connected this disk to my laptop via the provided USB cable. I then used the following command: rsync -r -t -v --progress --delete -c -l -z / /media/C4E41A11E41A0678/Moonface_BKP/ I ran this for a long (long long) time when i noticed that what had been backed up to the HDD began to be backed up. In other words, when i ran the command, it created a /media directory and a C4... directory below that and kept recursively backing up this directory (since, I suppose, I was backing up the hard drive itself, too). So...what's the proper way to use rsync?

  • OpenSSL: how to setup an OCSP server for checking third-party certificates?

    - by StackedCrooked
    I am testing the Certificate Revocation functionality of a CMTS device. This requires me to setup a OCSP responder. Since it will only be used for testing I assume that the minimal implementation provided by OpenSSL should suffice. I have extracted the a certificate from a cable modem, copied it to my PC and converted it to the PEM format. Now I want to register it in the OpenSSL OCSP database and start a server. I have completed all these steps, but when I do a client request my server invariably responds with "unknown". It seems to be completely unaware of my certificate's existence. I would greatly appreciate if anyone would be willing to have a look at my code. For your convenience, I have created a single script consisting of a sequential list of all used commands, from setting up the CA until starting the server: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/AllCommands.sh You can also find the custom config file and the certificate that I am testing with: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/ Any help would be greatly appreciated.

  • Bluetooth not seeing mouse (Fedora)

    - by Chris
    I have a Lenovo S10 'netbook' that I've installed Fedora 17 ("LXDE spin") on. So far pretty much everything works great, except, the on-board Bluetooth. lsusb shows the controller present (0a5c:2101 Broadcom Corp. Bluetooth Controller), hcitool dev shows hci0 present, but when I put my mouse ("Lenovo Bluetooth Laser Mouse," which works perfectly paired with a MacBook Pro, MacBook Air, Mac mini, and Lenovo SL500 (with a USB dongle; running Windows 7)) into pairing mode and run hcitool scan (reports "Scanning ..." and, without further information or error message, returns to the shell prompt), blueman-manager, or bluetooth-wizard (from the gnome-bluetooth package) and try to detect the mouse, I get nothing... Frustrating! Thanks anyone who can point me in the right direction!

  • Printing from a Linux using an Acer Aspire Netbook

    - by JoelFan
    A friend asked me to check why their Linux Acer Aspire netbook can't print to their HP printer. When I plugged in the USB cable, the a "balloon" popped up on the netbook saying it was installing the printer. But the printing does not work. I was able to get into a Settings area and click on Print Test Page but nothing happened. If it was Ubuntu, I would go into the Log File Viewer, but I couldn't find that on whatever Linux flavor the Acer is running. I couldn't even figure out how to get to a terminal (shell) window. I tried searching the HP and Acer sites but nothing seems to apply to this issue.

  • Advantages of Terminal Server instead of normal client-Server installation?

    - by Sam
    What are the advantages of using a (Windows) Terminal Server and thin clients instead of using a normal Server and full clients? So far I've only really used normal servers and clients, but now customers ask about terminal Server, and I'd like to know pro's and con's of using them instead of an "old-fashioned" client-server network. Some things I can guess: easier administration (don't need to install/update office/stuff on 20 computers but only on the server). Easier backup (no need to backup client computers). And I'd guess it would be hard (impossible) to connect and use local (like USB) hardware with Terminal Server? What else are the reasons for or against switching to Terminal Server?

  • Windows 7 x64 how to verify integrity of ALL files on an NTFS disk?

    - by kilves76
    Looking for a tool that would verify integrity of ALL files on a Windows 7 x64 NTFS disk reliably? This is for testing of experimental defrag software, so it really needs to be secure and foolproof. I know it will take a long time, there's millions of files on the disk, but safety just cannot be compromised in a situation like this. Freeware solution much preferred. Can be either Windows software (=inducing pitfalls about files changing due to booting Windows) or a stand alone boot (for example linux boot cd + usb key for storing chksum/metadata).

  • Looking for a free/cheap backup solution on OSX for NTFS external HDD [closed]

    - by Steve Middleton
    Hi, I'm looking for an incremental backup system on OSX that plays nice with USB NTFS-formatted external HDDs. I an currently using NTFS-3G (http://macntfs-3g.blogspot.com/) to work with the HDD, but since Time Machine doesn't work with NTFS drives, I have just been manually copying files from my HDD to back it up (ugh). I need to use an NTFS drive because I am going back and forth between Windows machines at my school and a mac at home. I have no permissions at my school to install any Windows software, so I am forced to find a OSX solution. Please -- any help you can give me would be greatly appreciated! Thanks!
