• Windows Server 2003 IPSec Tunnel Connected, But Not Working (Possibly NAT/RRAS Related)

  - by Kevinoid

  Configuration I have setup a "raw" IPSec tunnel between a Windows Server 2003 (SBS) machine and a Netgear FVG318 according to the instructions in Microsoft KB816514. The configuration is as follows (using the same conventions as the article): NetA | SBS2003 | FVG318 | NetB 10.0.0.0/24 | 216.x.x.x | 69.y.y.y | 10.0.254.0/24 Both the Main Mode and Quick Mode Security Associations are successfully completed and appear in the IP Security Monitor. I am also able to ping the SBS2003 server on its private address from any computer on NetB. The Problem Any traffic sent from a computer on NetA to NetB, or from SBS2003 to NetB (excluding ICMP Ping responses), is sent out on the public network interface outside the IPSec tunnel (no encryption or header authentication, as if the tunnel were not there). Pings sent from a computer on NetB to a computer on NetA successfully reach computers on NetA, but the responses are silently discarded by SBS2003 (they do not go out in the clear and do not generate any encrypted traffic). Possible Solutions Incorrect Configuration I could have mistyped something, somewhere, or KB816514 could be incorrect in some way. I have tried very hard to eliminate the first option. Have re-created the configuration several times, tried tweaking and adjusting all the settings I could without success (most prevent the SA from being established). NAT/RRAS I have seen multiple posts elsewhere suggesting that this could be due to interaction between NAT and the IPSec filters. Possibly the NetA private addresses get rewritten to 216.x.x.x before being compared with the Quick Mode IPSec filters and don't get tunneled because of the mismatch. In fact, The Cable Guy article from June 2005 "TCP/IP Packet Processing Paths" suggests that this is the case, (see step 2 and 4 of the Transit Traffic path). If this is the case, is there a way to exclude NetA-NetB traffic from NAT? Any thoughts, ideas, suggestions, and/or comments are appreciated.

• Which program is locking all my executable files?

  - by Tom Wijsman

  When updating any software product, as well as manually trying to replace .exe files, it says that access is denied to the file and in fact the System process is holding a handle to the file when I check it with Process Explorer. This must be a driver or something that is malfunctioning was my first though, but now I wonder how I figure out which driver / program is doing this and why it is so. Unlocker doesn't seem to be working for me, unless someone can tell me how to use it properly other than making it appear a magical wand in the notification area.... This is what Unlocker puts in my event log: The description for Event ID 1060 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: \??\C:\Program Files (x86)\Unlocker\UnlockerDriver5.sys the message resource is present but the message is not found in the string/message table Upon searching event 1060 I get: <file name> has been blocked from loading due to incompatibility with this system. Perhaps it is because I have 64 bit?

• DRBD as a block device for XEN VM (Centos 5.3)

  - by SaberTooth

  Hi all, I have setup a drbd resource between 2 server nodes - everything works correctly when doing sync tests between the two. (I want to create a HA cluster using drbd,xen and heartbeat) However, when I try and create a XEN VM with Centos as guest operating system, I get through to the partitioning screen on the install but when I select a partitioning type the next screen gives me the following error : "An error has occurred - no valid devices were found on which to create new file systems. Please check your hardware for the cause of this problem." This is the first time attempting create a setup like this and searching Google does not help much... my config files for DRBD and XEN....

• Second CPU missing of Dual Core

  - by Zardoz

  My Lenovo T61 has a dual core CPU. I just noticed that under Ubuntu 10.10 only one CPU is recognized. I know that once both CPUs worked. Not sure since when the second CPU is missing. Maybe since the last kernel update. Currently I am using linux-image-2.6.35-23-generic (for x86_64). What can I do to enable the second CPU again?

• How to force the start and end date of a task in Microsoft Project to be on the same day?

  - by Hauke P.

  I have a task called "Interview person A about topic X". The task's duration is set to 2 hours. The start date of the task should automatically be calculated taking dependencies and resource availabilities into account. My question boils down to: How can I force this task to start and end on the same date? Background: In my case, Microsoft Project sets the start date to a Friday at 5pm. As my working hours are set to 8am to 12am and 1pm to 6pm (Mon-Fri), Microsoft Project "splits up" the task at 6pm on Friday and plans to continue it at 8am on the following Monday. However, it does not make any sense to stop the interview on a Friday and restart it on Monday. Therefore the automatic suggestion is not helpful in this case. That's why I'm looking for a way way to force the task to start and end on the very same day. (In my example, I'd like Microsoft Project to delay the start date of the task until Monday 8am as this is the first time slot in which the task "fits in completely".) By the way: I have lots of such cases... for that reason it would be really great if there was a solution that doesn't just deal with this single special case.

• Get Matrox Millenium video card working in Ubuntu 9.10

  - by wcoenen

  I have installed Ubuntu 9.10 on an old PC and it is mostly working, except for some heavy drawing defects that show up whenever I start dragging a window or scrolling inside a window or menu. It looks like the video driver copies the rectangle being moved to the wrong location. I have taken a look in /var/log/Xorg.0.log and the following line shows the detected video card: (--) PCI:*(0:0:8:0) 102b:0519:0000:0000 Matrox Graphics, Inc. MGA 2064W [Millennium] rev 1, Mem@ 0xf9800000/16384, 0xfb000000/8388608, BIOS @0x????????/65536 (==) Using default built-in configuration (30 lines) (==) --- Start of built-in configuration --- Section "Device" Identifier "Builtin Default mga Device 0" Driver "mga" EndSection How do I fix the drawing defects? It turned out that the 24 bit color depth (automatically selected by ubuntu 9.10) was the problem; apparantly the mga driver doesn't handle this well for cards with little memory. I took the following steps to resolve the issue (you can skip the first three steps if you already have a semi-working xorg.conf file): Reboot ubuntu in recovery mode, to get a root console without X running. Run Xorg -configure to generate a xorg.conf.new file Copy the file to /etc/X11/xorg.conf with cp xorg.conf.new /etc/X11/xorg.conf (assuming it didn't exist yet; that's why I generated it) Open the new config file with sudo nano /etc/X11/xorg.conf and make sure the screen section is configured for 16 bit color depth like this: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1024x768" EndSubSection EndSection I can't guarantee those were the only important changes I made - I tried a few things in my attempts to create a valid xorg.conf file. But I'm pretty sure that the screen section was the important part.

  Just now I tried to make a duplicate copy of my Windows XP Pro SP3 CD. I had set 32X speed while the max speed allowed is 48X. And checked "Verify the Data after burning". I didn't observe how much % did it complete. But after 15 mins (which is sufficient period to burn disc), I heard "Fatal Error" sound. When I saw the monitor, There was a message box which was showing "Error while burning Disc", I saved the error log which you can find here click_me. How do I acknowledge that burning process is done?? Well. my PC is able to read the CD and CD is bootable too.. I am not sure .. whether the burning process got failed or the verify Process!

• Trying to retrieve data with a thermaltake blacX enclosure: Windows 7 believes the drive to be "uninitialized"

  - by Peeter Joot

  I have a laptop that won't boot. It appears to be a power problem ... laptop auto-turns-off within about 10 seconds of pressing the power button (with power buttons lighted temporarily and no display with or without external monitor). I've followed the dell troubleshooting guide which suggested reseating the memory modules and the hard drives, but that didn't help. Before trying to have the laptop serviced, I wanted to get some data off off the hard drive. I bought a thermaltake blacX enclosure, intending to use this to both use to retrieve the drive data with, and then later use as external storage. Following the instructions (insert cables, insert drive power on) goes fine, and Windows 7 on another laptop installs the device driver software. However, no drive letter shows up in 'Computer'. Under Computer-manage-storage I see the drive is there, and there's an option to "initialize" the drive. The Windows "initialize" dialog gives me the option to pick between "MBR" and "GPT" partitioning, which sounds like a good way to destroy the data on the drive. I'm thinking that I've purchased the wrong device for the job (or that my old drive is damaged). The old drive to recover info from is a Western Digital 500G/7200rpm SATA drive if that is relavent. Both the original laptop and the one I'm using for recovery are running Windows 7. Does anybody have experience with using a blacX enclosure to recover data off an already formatted drive?

• What to do with old laptop screens?

  - by Lord Torgamus

  This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses need not be geared towards those particular models' screens. Rules, based heavily on the original question's: Objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, be plain ol' fun, serve a social purpose or benefit the community. Your answer need not be limited to only one screen. For a really good answer, I'll go out and buy additional leftover screens. Your answer need not be limited to one project per screen. If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a useful purpose; art is nice, but functional art is way better. Thanks in advance, folks. EDIT: Found another related question. Fun projects to do with an old 17" LCD monitor EDIT 2: I, for one, am enjoying the new outpouring of creativity here. Best fifty bucks... I mean, rep points... I ever spent. EDIT 3: That does it. At the end of the week, there was a tie for most votes between the accepted answer and the game platform answer. The game platform answer was cooler, but less reasonable as a project to actually do; in other words, it was more moon rocky. Unfortunately, I think fencepost had the best comment on the topic, which is that displays on their own have no good interface. Thanks for playing, everyone!

• Display errors using VMWare Player and Remote Desktop on Windows XP

  - by Tim

  I've come up against a weird display issue that I can't seem to find any "fix" for. When I first boot up my computer, everything behaves normally. If I start to use VMWare Player and/or Remote Desktop, my desktop starts having some odd video issues. The frames for some windows aren't drawn at all, if I move windows around rapidly, the area under where the window used to be isn't cleared (still shows artifacts of the content of the window), etc. In some cases, the minimize / restore / maximize buttons aren't drawn (but are click-able if you can guess where they are). I've tried the usual stuff - current drivers all around, using a single monitor, etc.. none of it seems to have any bearing. If I try to disable hardware acceleration, it tends to crash the computer. As I said earlier, it's running Windows XP, dual monitors, an NVidia en8400GS video card, asus p7p55d motherboard. Not sure what other pertinent details are needed. I would appreciate any help or suggestions!

• Low-profile, PCI Express, x1 video card with VGA-out?

  - by Dandy

  I just bought an Acer Aspire EasyStore H340 system (http://us.acer.com/acer/productv.do?LanguageISOCtxParam=en&kcond61e.c2att101=54825&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=450&ctx1.att21k=1&CRC=936243954) It comes with Windows Home Server, which I don't particularly care for (too dumbed down for my liking)--I bought the box mainly for the form factor, and intend to install Server 2008 on it and have it run as a small domain controller. The geniuses at Acer however went out of their way to ensure you can only run Home Server--you can only connect to it via the Home Server Connector software, as it has no video-out whatsoever (so essentially, there's no way to even get into the BIOS). It only has a low-profile, PCI Express x1 slot. It turns out to be way harder than I thought to locate a video card that both has an x1 connector, and is low-profile (I'd really rather not snip the bracket at the back just so it'll fit the case). I know they're out there, and I've seen one with Display Port outputs, but I don't have a monitor with this connection. So to reiterate, it needs to be: - x1 connector - low profile - VGA out (though DVI would be okay; I have some spare adapters) Can anyone recommend anything at all?

• Relevance and Necessity of SNMP

  - by Adam Tannon

  Edit: I am in the process of designing a Java-based monitoring tool that will send back periodic "health checks" of a Java app deployed to a cluster of GlassFish servers. I am trying to figure out the best protocol for this monitoring tool to send information back to the monitoring server on. After an initial research effort on my part, it seems like SNMP is just a protocol for monitor-type applications to communicate the "health status" of something (a part of a network, a server, a cluster, an application, etc.) to the rest of the network. If the above is incorrect, please correct me!!! Assuming the generalization is more or less accurate, my next question is: why is this a protocol!?!? In the age of REST/SOAP/TCP protocols, why is there the need for a standardized protocol that only fits one type of application (monitoring)? In other words, if I'm a developer assigned to building a new monitoring tool that periodically polls a server and reports on its CPU and available memory, what advantages does SNMP give me over just POSTing to a RESTful API via plain 'ole HTTP? I'm sure I'm missing something here - I just need someone to help connect the dots! Thanks in advance!

• MySQL permissions error when showing databases

  - by Tony

  I was trying to install homebrew and very very stupidly did this: sudo chown -R $USER /usr/local The Homebrew instructions say to do this and I'm not much of a sysadmin so I took their word for it. Lesson learned (although I wouldn't really know how to test this...seems like an "undo" script would be super valuable here) Anyway, what is done is done, but now I get this error: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 548 Server version: 5.1.33 Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> show databases; ERROR 1018 (HY000): Can't read dir of '.' (errno: 13) I tried chown-ing back to root with no avail. Does anyone know how I can fix this without reinstalling mysql? Optionally, if I have to reinstall mysql, how can I dump my databases without access to the command line so I don't lose all of my data. Thanks!

• Windows Server 2008 is stuck at "configuring updates - stage 3 of 3 - 0% complete"

  - by Chris

  This has happened the last two times I've done updates to this system, and I really have no idea what is going on. It is installing a only a month's worth of updates. It only responds to ping and no services are up, so I can't view the system remotely (I have to hook up a monitor to see this message). In the past I've just restarted the system at this point and it eventually finishes updating. I want to know what I can do to avoid this situation, how to diagnose what is going on, and how to get any kind of remote access during the updates. Edit: I can start the machine in safe mode (where I did nothing but backup some files). I restarted and it no longer tries to do a windows update, just goes to the desktop where everything seems extremely broken. I can click on some things, but not launch most programs. I guess all I can do at this point is do a system restore or something. Edit: Re-installed windows on this system yesterday. That's my usual solution to issues I don't feel like diagnosing, like this one.

• Why is my computer randomly restarting? How can I fix it?

  - by kinglime

  I have a custom built desktop computer that I've been using since about a year ago. The main specs are: ASUS P8Z68-V LE Motherboard Intel Core i7 2600k Corsair Vengeance 16GB Ram ASUS ENGTX570 GPU Corsair TX650M PSU I was running an overclock of 4.4ghz for my cpu (I have a Hyper212 EVO) and 1600mhz for my RAM but have it currently turned off due to my issues. I am also currently running Windows 8 but this problem occured in Windows 7 too. Basically my issue is that seemingly randomly, with no pattern my PC will reset itself and ASUS Anti-Surge will alert me that something went wrong. This issue is not related to system stress. I can run it fine for an hour maxxed out on Prime95 then later I can be watching a mere YouTube video when it will randomly reset. This has been occurring probably for the last two weeks and it seems to be getting worse. I believe this might be related to the power supply but when I monitor it in the bios and in Windows it appears to be putting out the proper voltages. Also possibly related or not but my Nvidia drivers frequently temporarily fail and then warn me of some kind of kernel error? If I have to buy a new power supply that is what I'll do but I want to make damn sure that's the only issue at hand. Thank you everyone in advance, please help me diagnose the issue and tell me what I can do to fix it. If you need any additional info about my setup please ask me.

  My CPU was heating up to around 65 deg C and last time this had happened (about a year ago), I got thermal paste put between the CPU and heat sink and this managed to get it down to about 45 - 50 degrees. This time, I got some thermal paste and put it myself. However, my PC is not showing the POST display and not starting up. This is what happens LEDs light up HDDs spin Mouse is getting power All fans including the processor fan starts No display on monitor No diagnostic beep sounds (no sounds at all) What I have tried Removing everything including RAM, HDD, PCI cards, AGP card Boot up machine No changes from first state. What steps can I take to figure out where the problem lies? Note (might be important) When I removed the heat sink, the processor came out with it (it was stuck to it inspite of the processor latch on) Had to pry it separate with a screw-driver.

• Did my hard drive fail or is it something else?

  - by Julian

  Last night while I was watched a movie on my laptop the external monitor just went blank and the built-in display froze. Weird I thought, so I restarted it only to be greeted with this heart-breaking message. "No Operating System Found". After a few panicked restarts I accepted the fact that my hard drive might be done :(. Being the resourceful technie that I am, I whipped out Ubuntu Live on my old Flash Drive and was up and running before day break. I cannot access the hard drive through Ubuntu (which I expected) but I also cannot access my DVD drive either! This got me thinking that it might not be the hard drive and some other component that they hdd and the dvd uses. Hopefully this is the case. Which component is the most likely culprit? What tools can I use from Ubuntu Live on my USB flash drive to find out? I'm in a bad place without my hdd, thanks in advance for any assistance provided! P.S. My laptop makes a weird noise when I try to access or eject my DVD within the slot. Also my HDD makes a weird noise sometimes. Not sure how to describe it. System Specs: Dell 1558

• Finding bluetooth link key in Win7, to double pair a device on dualboot computer

  - by Ilari Kajaste

  How can I dig up the bluetooth link key for a paired device in Win7? Is this something that is dependent on the bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Win7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their bluetooth traffic. Background: I dualboot Win7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one bluetooth adapter and thus only one bluetooth address, I cannot do two pairings to the phone, since on the second pairing (windows) the phone just replaces the previous pairing (linux) to the same bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on linux, then on windows, and then replace the link key on linux side with the one windows negotiated. I can find the linux side pairing key from /var/lib/bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on windows side I can't find the key. According to the forum post, on windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Win7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security

• Window too big to fit the screen!

  - by syockit

  I'm using Windows 7 on a 8.9' monitor with 1280x768 screen resolution. Using the might of arithmetics, I'm able to determine that my dpi (actually ppi) should be 167. Win7 is really helpful in that it doesn't have to restart to apply new dpi settings, unlike its predecessors (though I'd rather it applies straight away). The problem with small monitors in Windows is that when you come across windows too big to fit the screen, you can't move the title bar far above it. In X window managers I used in the past, you could alt-drag the window to anywhere you want, but in Windows, even if you alt-space and select move, it will automatically push the window back until the title bar is visible. I'm looking for a solution that either: allows me to move window freely without regard to titlebar visibility, or attach a scrollbar to existing window, or EDIT: create virtual desktops that allow me to span windows over 2 desktops, or EDIT 2: allow me to set larger virtual resolution, then pan & scan. EDIT 3: I found some progs that might do some of the above: 1) AltDrag allows me to drag, resize using alt and left/right mouse button. Neat! Best solution so far. 2) GiMeSpace Desktop Extender is supposed to allow me to scroll desktop. Didn't work. The other new version, GiMeSpace Ultimate Taskbar worked, but it destroys my Superbar, replacing it with its map.

• Updating ASUS BIOS on Windows 7 64bit

  - by joesavage

  I've recently decided that I want to try and utilize my two graphics cards so that I can have a dual monitor setup. Unfortunately Windows only seems to notice my most recent graphics card installation - and so I've been told that I should look into my BIOS and try to enable two graphics cards. I could not find this setting anywhere in my M2N68-AM Plus v0210 BIOS. After some further research I figured that I should perhaps upgrade my BIOS, so I searched and managed to download the latest version (v1804) as a ROM file. However I am having difficulty figuring out how to install it. I've tried using the Asus EZFlash feature built into my BIOS, but when trying to load up a variety of different ROMs that are for my motherboard/BIOS I get the error: Boot block in file is not valid! I'm not totally sure what I should do to fix this, so I'm looking into other methods of upgrading my BIOS - however I can't really find any solutions that seem to work. Asus Update is for 32-bit only, AFUDOS doesn't appear to work on my Windows 7 64-bit system (I think it's supposed to run in DOS or something - but that just sounds confusing since I know nothing about DOS). Could anybody help me with this?

• What does SQL Server's BACKUPIO wait type mean?

  - by solublefish

  I'm using Sql Server 2008 ("R1"), with some maintenance plans that back up my databases to a network share. Some of my backup jobs show long waits of type "BACKUPIO". Of course it seems like this is an I/O subsystem limitation, but I'm skeptical. Perfmon stats for I/O on the production (source) server are well within normal trends for that server. The destination server shows a sustained 7MB/s write rate, which seems incredibly low, even for a slow disk. The network link is gigabit ethernet and nowhere near saturated. The few docs I've turned up about BACKUPIO indicate that it's not specifically a wait on I/O, surprisingly enough. This MSFT doc says it's abnormal unless you're using a tape drive, which I'm not. But it doesn't say (or I don't understand) exactly what resource is missing. http://www.docstoc.com/docs/24580659/Performance-Tuning-in-SQL-Server-2005 And this piece says it's not related to I/O performance at all. http://www.informit.com/articles/article.aspx?p=686168&seqNum=5 "Note that BACKUPIO and IO_AUDIT_MUTEX are not related to IO performance." Anyway, does anyone know what BACKUPIO actually means and/or what I can do to diagnose or eliminate it?

  I am using nagios 3.06 to monitor the servers. When a service is critical, it sends a mail, but when a server is down no mail is sent. Even if all the services go to critical state, no mail is sent. I have the following configuration: define command {     command_name notify-host-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$" "******** Nagios ****\n\n Host: $HOSTNAME$\n Description: the server is down" } define command{     command_name notify-service-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$: $SERVICEDESC$ ($NOTIFICATIONTYPE$)" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nDate/Time: $LONGDATETIME$\nAdditional Info:$SERVICEOUTPUT$" } The python script is a script to sent a mail. It works if I execute it from the command line, but it doesn't sents an email from nagios. What I am doing wrong? UPDATE: The contact data is: define contact{     contact_name root     alias Root     service_notification_period 24x7     host_notification_period 24x7     service_notification_options w,u,c,r     host_notification_options d,r     service_notification_commands notify-service-by-email     host_notification_commands notify-host-by-email     email [email protected] } define contactgroup{     contactgroup_name admins     alias Nagios Administrators     members root }

• Files showing in smbclient but not smbmount

  - by Staale

  I have a samba folder that I try and access through smbclient, and I can browse it just fine. However, mounting it through smbmount, all the folders under the share are empty. I can list the folders directly under the share fine, but they all appear empty. smbclient: # smbclient //server/share -U username -W workgroup password smbmount # sudo smbmount //server/share mntpoint -o user=username,workgroup=workgroup,password=password I have also tried with domain=workgroup instead of workgroup, both give the same result. No error messages, everything mounts fine, but all the folders under mntpoint are empty, despite the same folders being non-empty when using smbclient. Are these using different libraries? How can I debug the error? Additionally, if I try to mount //server/share/folder, doing an ls results in a segmentation fault. Using dmesg I find: kernel BUG at /build/buildd/linux-2.6.28/fs/cifs/cifs_dfs_ref.c:315! Full trace: http://pastebin.com/m70adc213 Using a credentials file, I first get empty dirs, then Resource temporarily unavailable. In my dmesg I see the following output: CIFS VFS: compose_mount_options: Failed to resolve server part of \\srv\share to IP: -11

• Dedicated Mouse and Keyboard on Virtual Box VM

  - by Myersguy

  To all super users, Currently I am trying to run virtual box on my second monitor, with a dedicated mouse and keyboard. However, doing so has not proven easy. There has been times where the mouse works, but not the keyboard, vice versa, or nothing works at all. The biggest problem I am running into is this: When enabling the USB mouse and keyboard from the VM, I get an error: 'USB Device is busy with a previous request.' The only thing that is using second mouse and keyboard, however, is Windows. The other error I have received stated that the VM was unable to create a proxy for the device. Additionally, the VM occasionally will disable the secondary keyboard entirely, requiring me to unplug and replug it into my PC to re-enable it again. Keyboard auto-capture is disabled, and while a solution I was reading online stated to turn off mouse integration, that option is grayed out on my machine. Any help would be appreciated. Thanks. /firstquestion.
