• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• Unable to connect to another computer from the Task Scheduler on Windows 7

  - by Clem

  I am getting the following error when trying to connect to another computer from the Task Scheduler on Windows 7: "The remote computer was not found." The computer that I am trying to connect to is definitely on the network as I can ping it and browse its shared folders in Windows Explorer. Note that I get the same error message when trying to perform the same operation from Performance Monitor. This suggests that I need to something to enable remote connection to the Task Scheduler. I am not very experienced with Windows administration and I am not sure where to look. To give a bit more context, I want to use the Task Scheduler to automatically start Perf Mon on a few machines at my company. I'd like to setup the Task Scheduler remotely. Does anyone know what I need to do?

• How to find out if the screen is WLED or RGBLED on Dell Studio XPS 16?

  - by Abhijeet

  I just ordered the Dell Studio XPS 16 with i7 and 16" RGBLED screen. This upgrade from WLED LCD to RGBLED LCD charged me more $$. But now when I view the order online, it lists this part as "320-8335 Premium FHD WLED Display, Obsidian Black, 2.0 MP Webcam". When called Dell, the rep says this part is RGBLED screen and the "premium" is for RGBLED. I want to make sure they are shipping me the RGBLED screen and not the WLED. Is there any way to verify this after I receive (either from Device Manager or BIOS or somewhere in system settings)? Also, is there any published specifications / criteria that we can run (some third party software) on this monitor which can tell if this is WLED or RGBLED?

• How can I use 2 monitors plus laptop with my Dell e6420 w/ Nvidia nvs 4200m

  - by KallDrexx

  I have just hooked up a 2nd external monitor to my Dell e6420 laptop with a Nvidia NVS 4200m graphics card, running Windows 8 64 bit. However, the computer won't let me have both monitors and the laptop display active at the same time. I installed the latest Nvidia graphics drivers (310.70) but it claims that my GPU can only support up to 2 monitors. Nivdia's website implies differently (as does various other laptops around the office). The monitors are connected both via DVI to my dell docking station that has multiple DVI ports. Both monitors are working correctly, I just can't get all 3 working together. Attempting to download the driver from dell fails, as their driver installer is broken apparently Any ideas?

• Virtual Machine files on ramdisk doesn't run faster than on physical disk

  - by Landy

  I installed total 36G memory (4x8G + 2x2G) in the host (Windows 7) and I used ImDisk to create a 32G ramdisk and format it to NTFS file system. Then I copied the virtual machine (in VMware Workstation format) folder, including vmx, vmdk, etc... to the new created ram disk. Then I tried to power on it in VMware Workstation. What made me surprised is that the performance is not better than before. It cost almost the same time to power on the Windows 7 VM. I check the Resource Monitor in the Windows 7 host, and the statistics of CPU, disk, network are rather normal. The memory has reported 3000+ hard fault/sec when guest OS boot then drop to 0 after the guest powered on. Any idea about this issue? I had thought the performance of ramdisk will be better than physical disk in this case. Am I wrong? Thanks.

• How to play from mic to speakers in Ubuntu Karmic?

  - by vava

  Ok, I have a silly problem. I have few bluetooth headsets lying around and I want to make DYI baby monitor out of them. All I need is for some application to listen to the mic and send it to the speakers. Loopback (even though it doesn't work) is not good enough, it'll send sound from the mic to the speakers in the same device but I need it to go across devices. So does anyone know some application that can do that? I'm looking for something small and easy to use, not jackd or similar.

• something is downloading in background Linux

  - by wisdom

  My laptop boots normally to Linux -LinuxMint- and immediately I like to open gnome-system-monitor but the shock is that something is downloading(the problem has been out 2 days ago) and nothing I run yet ! I did iftop in terminal but nothing strange -a screen shot provided-, also I tried nethogs which showed nothing at all. The more complicated when I reboot and same problem is there so I can't browse/surf Internet, no one connected to my network can browse any more it's absorbing the stream horribly! After many reboots it will go to normal state(no background downloading). But really I can't figure out the problem going behind the scene ! Any suggestion,any help would be appreciated...thanks

• Active DFS node did not restore after failure

  - by Mark Henderson

  On Tuesday we had a Server 2008 R2 DFS-R node go offline unexpectedly. DFS did the right thing and started routing requests to a different node, which was in a remote site. This is by design, because even though it's slow, at least it's still working. We had the local DFS-R node back online within an hour, and it had synced all its changes 10 minutes after that. 3 of the 5 terminal servers reset themselves to the local DFS node, but the other two stayed pointing at the remote DFS node for three days, until someone finally piped up about how slow requests were. What reasons could there be why some, but not all, of the server reverted? Is the currently active DFS node for a namespace exposed anywhere in the OS (WMI, or even scripts) so that we can monitor the active nodes?

• Anti Aliasing dead

  - by Gazoza

  I have a problem with anti-aliasing. No matter the software settings, it seems to be gone. I tried driver updating and reinstalling, cleaning of the hardware, different monitor with different cablies, OS reinstalling and changing, none of which helped. I decided to change the graphic card, but that didn't work either. Moreover, I have a distinct impression that the jagged edges are worsening as time goes by. I think this is a hardware-related issue, but I don't know exactly what to do. If anyone here had similar troubles, and/or has an idea how to cope with them, I'd be very grateful. My current card is a nVidia GT610.

• How to cache streaming video and silverlight with squid windows reverse proxy

  - by V. Romanov

  We have an intranet web server running a silverlight application (ACTUS media monitor if anyone cares to know). The server is used to record video and stream it to clients through a CDN solution. We want to put a reverse proxy in between the server and CDN provider in order to remove the office network bottleneck that's currently strangling us. I've set up SQUID for windows on a separate machine outside the network using squid BasicAccelerator configuration setting. It seems to work as far as the reverse proxy is concerned, requests are forwarded and the application is working but it doesn't seem to cache anything (no space is used on the drive where squid is installed). I found to explicit setting to turn caching on in squid, so i assume it's on by default. Perhaps I need some other trick to make the video and/or silverlight cacheable? Any help will be appreciated. Any info you need to help me will be provided at once. Thanks in advance!

• Radeon hd 6570 black screen

  - by Sho

  I got some problem with new graphic card. Every time I use AMD Catalyst drivers on Windows or Linux, screen repeatedly goes black. This usually shows u when i open new cards in a browser, resize a window or run a program. Card runs smoothly on basic drivers but this means low resolution. 1940x1080 is native for my monitor so it causes a lot of problems. I've got a 600W Deus G1, so the power is not the problem. Maybe its a silly question, but would going form a vga cable to hdmi help to improve this situation? If not, can it be caused by slow processor or old mainboard? Im getting kinda confused about this whole thing...

• Our GoDaddy web server is drowning in temp files!!

  - by temp file guy

  We have a virtual dedicated server with a fairly large amount of traffic. We use GoDaddy using CPanel. We have 10GIG of space of which about 80% is not our content but logs and server utilities. Godaddy support is evasive and they are trying to encourage us to migrate to new service with 15GIG. Reviewing the large files we found the following: We have a ton old TMP files at this directory. /public_html/files/TMP/FILE_PERSISTANCE_PROVIDER: (no access) some large files in these directories. /usr/local/apache/logs/ - suphp_log (220M) - access_log (7M) - error_log (5M) /usr/local/apache/domlogs/ (no access) /usr/local/cpanel/ (no access) /usr/local/cpanel-rollback /tmp Questions: What can we safely delete or truncate? How can we change permissions on files with no access to delete? Is there utility to monitor and clean up temp files Other files/programs that we can delete? thanks!

• Flash CS5 projects panel totally gone?

  - by Jesse

  So, I popped open up Flash CS5 just now, and I couldn't find my projects panel. I was working on a dual screen set up previously, so my windows were everywhere anyways (sans external). I switched over to a smaller screen workspace, and popped opened the projects panel. Oddly enough, the code snippets panel came up instead. So, I switched off the code snippets, and tried again. I've been trying different ways of opening this panel for about 15 minutes, and I'm totally stumped. Some thorough googling didn't present any relevant results, so, StackOverflow, I turn to you. Is this a known issue? is there a secret backdoor way to open this panel? Am I totally missing something?

• Log monitoring using Zabbix

  - by Supratik

  Hi I am monitoring logs using Zabbix. I am trying to monitor a log file using Zabbix 1.8.4. I created an item using the following details: Host: Zabbix server Description: logger_test Type: Zabbix agent (active) Key: log[/tmp/scribetest/test3/test3_current,error,,100] Type of Infromation: Log Update interval (in sec): 1 sec Keep history (in days): 90 Status: Active Applications: Log files I created a trigger and attached it with the item logger_test using the following details. Name: logger_test_trigger Expression: {Zabbix server:log[/tmp/scribetest/test3/test3_current,error,,100].str(error)}=1 Severity: disaster The above settings works fine for the first time but next time the trigger shows ZBX_NOTSUPPORTED and after that item also shows "not supported" message. Can you please tell me if anything I am doing wrong here ? Warm Regards Supratik

• Problem with blue-sceens

  - by Oystein

  Hi I have a problem with my computer. I get bluescreens a lot. I get different bluescreen-codes everytime, and this happens randomly. This can happen when I boot my computer, when I'm surfing on the internett, when I'm away from the computer and are logged out... I tried to disconnect everything that was connected to my computer, beside the monitor. That didn't help. I have reinstalled Windows, changed memory, changed video card, but nothing of this helped, I still get bluescreens. I guess the problem here is the mothercard, CPU or HDD. But I want your opinion before I order anything new to my computer. Can you tell me what the problem is?

• Is it my motherboard?

  - by jarodrussell

  Early this week my home server (a Linux machine) threw a kernel panic. Yesterday is happened a couple of times. Then all of a sudden, when I plugged a USB stick in to run a memory test, the monitor stopped coming on. Now whenever I turn it on, the system gets power...I heard the drives spin, I see the processor fan spin, and the hard drive light comes on...but nothing happens. I put a video card in the AGP slot, but still nothing. The light on the power button that usually comes on stopped coming on. I took the memory out to see if it would beep, but nothing beeped. It's like it's getting power, but it's not coming on. Does this sound like a motherboard problem to anyone else? I think it is, but a second opinion would be greatly appreciated. Thanks.

• Sharing soundcard to network.

  - by zerkms

  Let's suppose I have a laptop (L) and desktop PC (D), both with Windows 7 onboard. It is SB X-Fi extreme soundcard with rather good 5.1 home theater connected. But it is not comfortable to watch video sitting on the sofa from my desktop (sofa is in the center of the room and D is in the corner), even though it is 23" monitor. So I'm watching everything from the laptop. So the question - is it possible somehow to "share" soundcard from D to L, so I will watch the video from notebook and listen the sound from the 5.1? L and D are connected via wi-fi (fast enough).

• AMD Radeon 7900 series: setting up 3 monitors

  - by Nilzone-

  I have an AMD Radeon 7900 series, which should support up to 6 screens. I'm having problems getting my third one working. Im running windows 8, and have installed all the latest AMD drivers. My screens are: Samusng syncmaster S27D391HS Samusng syncmaster S24B350H Samusng syncmaster S24B350H The first 24" monitor I use HDMI to DVI cable. The second 24" I use VGA to DVI cable. Lastly, for the 27" I use HDMI cable. The result is, no matter what I do, I never get more than two screens on simultaneously. I have also tried getting a DisplayPort to HDMI cable to use for the 27", but Im not sure if it was passive or active (didn't say on the box, nor did I ask). So my question is: is an active displayport to HDMI the solution, or is there someting else Im overlooking? (I have read similar posts on this subject, but I use a slightly different combo of cables. That is why I made a post of my own as well)

• Dedicated Mouse and Keyboard on VirtualBox VM

  - by Myersguy

  Currently I am trying to run VirtualBox 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.

• capture nimbuzz traffic

  - by lurscher

  I need to capture all the traffic, specially during login, between nimbuzz pc client and nimbuzz server. The reason is that i need to debug outgoing packets at login that mark the user visibility status in order to reproduce them in a in-house XMPP client application I've tried doing this with wireshark, but i seem to be pretty helpless with this tool. Also, the packets i've been able to see are all before the SASL negotiation happens, after that, i cannot see the xml packets being exchanged any help for how to achieve this task is greatly appreciated (preferably on Windows, since there is no nimbuzz client for linux, in any case i can install one in a VM and monitor the traffic between the VM instance in the linux host)

• Distributed Nagios Installation

  - by kruczkowski

  I'm looking for a plug-in or product that will act as a remote probe and perform tests then send back the results to the central Nagios server. Reason for this is that I'd like to monitor internal systems and servers at customers, but don't want to allow all the traffic passing the firewalls. Ideally I'd like a soft-probe that would be installed and then perform the tests and send back the results (via SSH) to the central Nagios installation. Does anyone know of a product or plug-in that would offer such service? If not Nagios, is there any other monitoring system that does such a thing (ideally open-source)?
