• How do I use Compiz on Linux to achieve what WinSplit revolution does on Windows?

  - by Bryce Thomas

  Hi there, I've used WinSplit Revolution for quite some time on Windows and have become attached to it. I'm now trying out a Linux OS (Ubuntu 10.04) and would really like to get the same functionality back again. After searching on the net I found a "grid" plugin (http://wiki.compiz.org/Plugins/Grid) for compiz which says that it was inspired by WinSplit revolution. I haven't installed the Grid plugin yet, because under the install section on that page, it says "Note that grid is now included in compiz so you're unlikely to need to fetch from git unless you've an old version of compiz", which would seem to suggest that the grid functionality has now been built into compiz somewhere. The thing is, I don't know where to find it in the CompizConfig Settings Manager nor how to set it up. All I want to have happen is that I get identical functionality to WinSplit revolution, where I press Ctrl + Alt + [some numpad key] to position a window on a screen and press Ctrl + Alt + [left or right arrow] to shift a window between dual screens.

• Windows 7 USB power lose after a few seconds / minutes

  - by Stefan Dunn

  My friend's computer has a problem where the USB ports causes problems with the power of some devices connected to the computer. The USB mouse has no problems, however the Wireless Adapter looses power after around 20 seconds of use and USB Flash Drives cause the computer to either freeze, lose power (and become unresponsive) or become disconnected (still shown in Device Manager, but not in My Computer) when trying to transfer any type of file to / from the computer. I have a suspicion it's the Motherboard but could it also be a Software problem? Tried a new case, RAM, CPU and GFX Card which had no effect. The problem occurs on both the Front USB and Back (Motherboard) USB Ports. UPDATE: Tried the USB devices with an Ubuntu Live CD and they work fine, could this mean it's a problem with Windows (x64)?

• Debian based OS: Show system notification on clipboard copy/paste events

  - by ifischer

  When working with Linux (Debian based), I often experience problems in relation to the copy paste commands: I copy something with Ctrl+C or by selecting it with the mouse, but when I try to paste it somewhere else, the clipboard is empty and nothing happens - whatever reason caused this. This annoys me, as I have to switch to the source application again and again copy the text. So to really be sure if something was copied into the clipboard I would like it if the window manager (be it Gnome, KDE, etc) would show a Desktop Notification (for example powered by libnotify) as soon as anything is copied into the clipboard, showing the content that has been copied into the clipboard. Is that possible by using one of the many clipboard managers out there (glippy, clipit, ...)? If not, can I write a (DBus?)-hook, which is triggered during copy-to-clipboard-actions, showing the content which is to copy inside the Desktop Notification? (The latter approach would be more interesting, since I'm interested in hooking into system events in general)

• Virtual fiber channel HBA in Solaris

  - by Phil

  We are trying to set up some virtual Fibre Channel HBA's in Solaris. This seems to be possible with NPIV. Creating NPIV's in a Solaris global zone works fine, but passing that NPIV to a zone didn't work at all. We tried to pass the NPIV as following: # zonecfg -z zone1 'info' zonename: studentz1 [...] device: match: /devices/pci@0,0/pci8086,25f9@6/pci8086,350c@0,3/pci1077,140@4/fp@1,0:devctl allow-partition not specified allow-raw-io not specified Wat we want to do is, set up an environment for SAN exercises. We don't have a physical host per student, so we try to virtualise that in some way (Solaris zones or VMware). It should be possible to display the WWN of the virtual HBA and mount the storage presented by the disk subsystem. Any ideas to pass the NPIV to a solaris zone or to virtualise this with vmware?

• SMTP port open - but not open

  - by Frederik Nielsen

  As some of you might know, I am setting up an exchange server. Now I ran into another problem: I cannot connect to the SMTP service from outside the server! The ports are opened in the gateway device (a ZyXEL USG50), Windows firewall is off. I see the packets travekl through the ZyXEL firewall, and I can also see the packets with wireshark on the server, so I know they are getting all the way in to the server. I also know it receives them, and sends out the reply - and this is where things go bad! Analyzing with wireshark, I get these errors in the return packets: Header checksum: 0x0000 [incorrect, should be 0x0779 (may be caused by "IP checksum offload"?)] And: Acknowledgment Number: 0x8e3337d1 [should be 0x00000000 because ACK flag is not set] What the (sorry my French) hell is going on? I really cant figure it out.. Thanks in advance.

• Hardware asset management systems

  - by Dave

  I need to track a bunch of specialized testing tools, They are hardware devices used for testing other equipement. Each device has a serial number and is sent out for use in testing. Occasionally they break and have to be sent to the manufacture for repair. I'm looking for an open source application (preferably a webapp) to help manage them. Right now we're using Excel and it's not scaling as we get more tools. They aren't computers so all the standard IT asset management systems don't really fit the bill. I found h-harmony, but that project seems dead?

• Implications of allowing Windows clients to use NTLMv1?

  - by Boden

  I have a web application that I'd like to authenticate to using pass-through NTLM for SSO. There is a problem, however, in that NTLMv2 apparently will not work in this scenario (without the application storing an identical password hash). I enabled NTLMv1 on one client machine (Vista) using its local group policy: Computer-Windows Settings-Security Settings-Network Security: LAN Manager authentication level. I changed it to Send LM & NTLM - use NTLMv2 session security if negotiated. This worked, and I'm able to login to the web application using NTLM. Now this application would be used by all of my client machines... so I'm wondering what the security risks are if I was push this policy out to all of them (not to the domain controller itself though)?

• Troubleshooting Windows Server 2012 storage spaces

  - by Iravanchi

  I'm trying the new "Storage Pools" feature on Windows Server 2012, and I've created several disks on the pool. When I restart the server, some of the disks (two, out of four) do not attach automatically, and don't show up in the list of disks. I can go to Server Manager File and Storage Services Storage Pools, and the faulty disks are listed with a yellow triangle beside them. The drive health in the properties are "unknown". But if I right-click and choose attach, the disk comes online, with all the content on it intact. But after another restart, it's the same story. I didn't find any relevant event in the event log, how can I find out why the drives are not attaching?

• How can I apply a DSP to my microphone in windows?

  - by user16315

  I'd like to be able to run my microphone through arbitrary DSP filters--Mostly for compression and amplification, but also noise cancelation would be nice. I'd then like to take that output and put it back in a virtual audio device that I could use as input for skype, mumble, teamspeak, or any other VOIP program. With a program like Virtual Audio cable, I can do the 'fake devices' part but as far as I know it does not allow any kind of filtering inline. Does a program like this exist? Or some combination of programs that can be combined to accomplish this?

• upgrade from windows server 2008 r2 std to enterprise

  - by Ravi

  We recently had to upgrade our servers from Win 2008 R2 Standard to Enterprise. The upgrade method was DISM. After the upgrade, a lot of weird things started to happen. Though Windows says it's been properly activated, we lost 1) RDP settings (disappeared from the Remote Setting tab of Properties of My Computer) 2) The option to join a domain is grayed out 3) The server had to 2 physical processors 12 cores each. Now, task manager or windows sees only 1 processor (or only 12 cores) 4) the amount of physical ram on this sever is 32 GB (Windows reports only 4 GB are usable) Has anyone encountered this before ? Thanks Ravi

• What could cause my LAN Pings be greater than 100ms?

  - by James Holland

  I have 2 servers (Both: Windows Server 2008, Dual Xeon 2.8Ghz, 32GB RAM, 8 x 15k SAS Drives). One of them is a DC / Web server / Exchange Server, the other is a SQL Server (2008). I have a 48 port Netgear GS748T Gigabit switch. When I ping from server to server, I get ping times <1ms, great, but when I ping from a PC, I get varying pings from the occasional <1ms to 500ms!! If I log into either server and look at Task Manager, CPU usage peaks at 20%, memory usage is 100%, but I am led to believe this is normal as Exchange will just use as much as you have, and release it when requested. Network usage peaks at 1%. I really don't understand how the ping can vary that much. I know I am giving very little info, but this is all I know, I apologise, but can anyone help? In response to question, I have pinged by both IP address and hostname, no difference in ping times.

• Can't reconnect to my RDP session

  - by Jeremy Stein

  I use a VM through RDP. When I'm done for the day, I just disconnect the session and reconnect in the morning. That allows me to pick up what I was doing and not close all the applications. As I'm the only user, this generally works well. Today, I can't reconnect to my session from yesterday. When I RDP, I get a new session. When I run query user, I can see my other session: USERNAME SESSIONNAME ID STATE IDLE TIME LOGON TIME me rdp-tcp#82 1 Active 15:00 4/22/2010 9:00 AM me rdp-tcp#91 2 Active . 4/30/2010 9:00 AM If I try to use Terminal Services Manager to remote control the other session, I get this error: Session (ID 1) remote control failed (Error 7044 - The request to control another session remotely was denied. ) Is there any way to reconnect to this session, or do I need to just kill it?

• Does Juniper Networks provide keyloggers with their software?

  - by orokusaki

  I noticed that I had a "USB Mass Storage Device" plugged in when there wasn't in fact anything plugged in to any USB port. I turned it off via Windows (XP), but it's quite concerning. This was after installing Juniper Networks' software for VPN access to an IT guy's stuff. I also notice there is a service called "dsNcService.exe" which apparently is sending information over the internet (even when I'm not in VPN access). The process restarts itself when I end it. Should I be worried that this software is tracking my keystrokes and broadcasting them to my IT guy?

• LM Sensors always returning same (invalid) value for one temp sensor

  - by pkaeding

  I am trying to monitor the temp sensors on a server, and plot them using Cacti. I have lm-sensors installed and working correctly. For example, here is the output from sensors: % sensors acpitz-virtual-0 Adapter: Virtual device temp1: +26.8 C (crit = +100.0 C) temp2: +32.0 C (crit = +60.0 C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +36.0 C (high = +105.0 C, crit = +105.0 C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +42.0 C (high = +105.0 C, crit = +105.0 C) However, when I try to get this data via SNMP, I get only one sensor's temperature correctly, and another one always returns 100.000 C: % snmpwalk -Os -c public -v 1 10.8.0.18 -m ALL lmTempSensors lmTempSensorsIndex.1 = INTEGER: 0 lmTempSensorsIndex.2 = INTEGER: 1 lmTempSensorsDevice.1 = STRING: temp1 lmTempSensorsDevice.2 = STRING: temp1 lmTempSensorsValue.1 = Gauge32: 26800 lmTempSensorsValue.2 = Gauge32: 100000 So, my question is two-fold: Why is the second sensor that is returned by SNMP giving a value of 100 C (when it should be 32 C) Why are my CPU core sensors not being returned by SNMP?

• Diagnosing high CPU waiting

  - by Will

  I have a monitoring server that is running icinga/collectd/graphite with about 50 hosts. I have noticed high load/slugging performance on the box. If you take a look at top, you'll see: Cpu(s): 0.6%us, 0.2%sy, 0.0%ni, 7.6%id, 23.4%wa, 0.0%hi, 0.2%si, 0.0%st Notice the HUGE %wa value, which as far as I know means a network or disk bottleneck. ifconfig shows no dropping packets and there's not a ton of bandwidth going on, so that leaves disk issues, right? There's not a lot of disk writing going on either...iotop is reporting we're only writing a little over 1 MB per second and the RAID tool reports everything is A-OK and write caching is enabled. How do I go about trying to figure out how to fix this? UPDATE: iostat -x output is: avg-cpu: %user %nice %system %iowait %steal %idle 0.62 0.10 0.31 9.65 0.00 89.31 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.21 33.34 83.55 16.54 1599.94 399.07 19.97 43.21 416.98 3.71 37.13

• SQL Server 2008 R2 cluster on Windows Server 20008 R2 issue

  - by Yousui

  I have a SQL Server 2008 R2 cluster on Windows Server 20008 R2. There are 2 nodes node1 and node2 in the cluster. When I start node1 and node2, I get the following statue information from them: From node1: C:\>cluster node Listing status for all available nodes: Node Node ID Status -------------- ------- --------------------- node1 1 Joining node2 2 Down C:\> From node2: C:\>cluster node Listing status for all available nodes: Node Node ID Status -------------- ------- --------------------- node1 1 Down node2 2 Joining C:\> I tried to use the cluster manager to investigate, but it seems it just can't connect to the cluster. How to investigate this issue? Thanks.

• How to convert PowerPoint presentations into a Kindle/E-reader friendly form?

  - by Shiki

  I have a lot of documents in .ppt and .pptx (blame the co-workers). I would like to read them on way home or elsewhere... when I have a little time to catch up with things. One thing I could do with the documents is cutting them together into one file. But saving that one even if a smaller version of PDF (according to Office 2010) results in a huge file. And PDF is hardly readable on a Kindle. I would need something .epub free, easy-on-the-device way. Is there such a thing? (Manually I could copy all the images down into native text and whatnot and create new presentations, save those, convert them. But that would just take a lot of time.)

• How to generate a round-numbers graph in Excel?

  - by tcheregati

  folks! Now, I have an Excel file with measurements I made of some color patches (I work at a Press company), with a device called spectrophotometer. Here it is: https://docs.google.com/open?id=0B0i8fdSf2ihzRlFYNWd4anItenM Density and Hue are two characteristics of each color patch. The thing is: I'm looking at a non-linear increase between the 25 Color Density measurements I took, but I NEED to know exactly how the color's Hue changes as the color's Density increases. For that, I needed Excel to give me round numbers for the X axis (for example 0,70 to 1,50 in 0,05 increments). And for that, obviously, I needed Excel to calculate the probable Hue Values corresponding to those ghost/round/not-given values of Density (like a kind of advanced rule of three). So, can anyone help me on that? Thanks a lot!

• Connect wired-only devices to a remote wireless access point?

  - by billpg

  Hi everyone. In building A, I have a Netgear wireless access point using WPA2. Works great, no problems. In building B, I have some devices that only have wired Ethernet ports. They can't see my access point. What I need is a gizmo that connects over-the-air to my access point in building A, talks WPA2, and converts the packets to and from a wired Ethernet port. Netgear-access-point in building A      (WPA2 WiFi) Wireless bridge device          <-- Looking for this.      (Cat5 ethernet) My devices in building B. I've looked for devices on Amazon, but the descriptions are infuriatingly unclear. It says it supports WPA2, but does it support it as a client? Grrr... Any recommendations please?

• Which driver for "ATI Mobility Radeon HD 3650" in a laptop?

  - by Lasse V. Karlsen

  We have some HP laptops here that comes equipped with a video card that identifies itself as "ATI Mobility Radeon HD 3650", like this one. However, which drivers do we choose? As far as we can tell, HD 3650 is desktop cards, or at least there are no drivers listed for that series with "Mobility" in their name. If I pick the following on the ATI Driver Download page: Graphics Windows Vista 32-bit Edition Mobility Radeon Then the dropdown for the card model contains X300, X600, X700, X800, X1300, X1400, X1600, X1800, 9600, 9700 and 9800 models, but no "HD" nor "36xx series". However, if I change to just "Radeon" for the last selection there, I can find a "Radeon HD 3600 Series" model in the list. Also, if I pick "Windows 7" as the operating system, I can find a "Mobility Radeon HD 3000 series" card, but no 3600. So, which one to pick? The main reason I ask is that they all seem to have some kind of problem installing, so neither seems to be the right one (they all crash with "Catalyst Install Manager has stopped working".)

• Configure custom SSL certificate for RDP on Windows Server 2012 in Remote Administration mode?

  - by Ryan Bolger

  So the release of Windows Server 2012 has removed a lot of the old Remote Desktop related configuration utilities. In particular, there is no more Remote Desktop Session Host Configuration utility that gave you access to the RDP-Tcp properties dialog that let you configure a custom certificate for the RDSH to use. In its place is a nice new consolidated GUI that is part of the overall "edit deployment properties" workflow in the new Server Manager. The catch is that you only get access to that workflow if you have the Remote Desktop Services role installed (as far as I can tell). This seems like a bit of an oversight on Microsoft's part. How can we configure a custom SSL certificate for RDP on Windows Server 2012 when it's running in the default Remote Administration mode without needlessly installing the Remote Desktop Services role?

• Server Performance

  - by Burt

  We have a dedicated server that we use to stage websites (our test server). The performance of the server has become really bad and we regularly have to restart it. When performance is poor I have checked task manager for the processes and memory but everything looks OK. We use a content management system and it is always when using the admin section of this CMS that we notice the performance degrade which makes me think it may have something to do with DB calls the CMS is making. Does this sound viable? Any other sggestions of how I can go about testing this? Thanks in advance...

• NTFS-3G is only mounting external drives as read-only

  - by Phanto

  I'm currently running RHEL 5.5, and I installed the ntfs-3g utility from here: http://www.tuxera.com/community/ntfs-3g-download/. I have also followed their instructions for auto-mounting NTFS USB drives here: http://www.tuxera.com/community/ntfs-3g-faq/#plugandplay. The problem I'm experiencing is that ntfs-3g is automatically mounting as root. In order for me to obtain write support, I need to navigate to the mounted device as root, and perform write actions with elevated privileges. Is there a way to mount USB NTFS volumes automatically without needing to sudo every write command? Thanks!

• Where to find and download a new suitable software? [closed]

  - by user63411

  Possible Duplicate: How do you find a new software to download? I see that the most time I spend on the computer I lose to just searching for suitable software. How you do it? What is your way to find software? Do you first go to a forum or google? Which torrent site? which P2P program, website or server? For example: "I need a software that have functions as a remote desktop and also lets you copy and paste (drag and drop - file manager). And after few hours searching on Google I downloaded LOGMEIN Pro2, but than I see that is just trial. So if I need to find alternative I will spend another whole day. Where to go? I am not an amateur but I need a better system. I need better introduction on how to find what is the suitable software.
