• How do I enable greedy MigrationHeuristic in Karmic?

  - by Matthew

  My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

• Color Profiles in Windows 7 vs. XP

  - by flxkid

  I have a Brother Color Laser Printer and an HP 8150DN. I have a local Windows 7 Pro machine that I do graphics work on. I created a letterhead that when printed from my machine looks dark and rich on either the mono HP or the color Brother laser. I take this same letterhead, and move it onto our network for use by our users which are all on XP. Then they print the same file, it is washed out on either printer. I've confirmed that the printer settings we're using are identical. I've confirmed that its not related to the program or even specifically to the letterhead. I can duplicate this with other files too. I'm down to XP vs Windows 7 being the issue. I'm fairly certain now that color profiles are involved. I have no clue how to fix it though. Any suggestions would be much appreciated.

• Listing group members using ldapsearch

  - by colemanm

  Our corporate LDAP directory is housed on a Snow Leopard Server Open Directory setup. I'm trying to use the ldapsearch tool to export an .ldif file to import into another external LDAP server to authenticate with externally; basically trying to be able to use the same credentials internally and externally. I've got ldapsearch working and giving me the contents and attributes of everything in the "Users" OU, and even filtering down to only the attributes I need: ldapsearch -xLLL -H ldap://server.domain.net / -b "cn=users,dc=server,dc=domain,dc=net" objectClass / uid uidNumber cn userPassword > directorycontents.ldif That gives me a list of users and properties that I can import to my remote OpenLDAP server. dn: uid=username1,cn=users,dc=server,dc=domain,dc=net objectClass: inetOrgPerson objectClass: posixAccount objectClass: organizationalPerson uidNumber: 1000 uid: username1 userPassword:: (hashedpassword) cn: username1 However, when I try the same query on an OD "group" instead of a "container," the results are something like this: dn: cn=groupname,cn=groups,dc=server,dc=domain,dc=net objectClass: posixGroup objectClass: apple-group objectClass: extensibleObject objectClass: top gidNumber: 1032 cn: groupname memberUid: username1 memberUid: username2 memberUid: username3 What I really want is a list of users from the top example filtered based on their group memberships, but it looks like membership is set from the Group side, rather than the user account side. There must be a way to filter this down and only export what I need, right?

• How to install old versions of gcc on Fedora without a VM?

  - by mikeh

  Hi, I need gcc 4.3 running alongside the shipped 4.4 on an FC13 machine. I can't do the VM solution discussed at http://serverfault.com/questions/88445/how-to-install-old-versions-of-gcc-on-fedora-12 since I need hardware access (CUDA computations on the graphics card). There's no compat-gcc-43 package (only compat-gcc-34). So I've built gcc by hand and am now trying to decide how to "install" it. Could anyone confirm that this was my only option, and/or suggest a best practice for how to manage the side-by-side gcc versions?

• dell u2410 3dMark Benchmark distortion problems

  - by Scanningcrew

  Ive been doing burn in testing for a new system I have put together and I am running into some video distortion problems with running the 3DMark benchmark tools (Both 06 and Vantage). The graphics will be fine, then sometimes during a test switch the screen will light up with thin horizontal ranibow lines (Something that looks very "glitchy") If i turn the monitor off and back on it clears up. All the tests "pass" and my system gets good marks but it concerns me if I might have problems with games (The screen returns to normal if I dont resest monitor and just let tests pass). I want to return a problem component now before its too late if it is something with the new hardware. Also, I am monitoring temp with thermal laser gun and the card itself is not going above 65c. Any ideas? System: Asrock x58 Xtreme - Last BIOS (1.80) EVGA Geforce GTX 285 w/ latest nvidia drivers (Connect via DVI1) Dell U2410(Set to 59hz refresh 1900x1202 -although I believe benchmarks run 1200x1024) Windows 7 Ultimate 64 12Gb DDR3 1600 RAM

• FreeBSD slow transfers - RFC 1323 scaling issue?

  - by Trey

  I think I may be having an issue with window scaling (RFC 1323) and am hoping that someone can enlighten me on what's going on. Server: FreeBSD 9, apache22, serving a static 100MB zip file. 192.168.18.30 Client: Mac OS X 10.6, Firefox 192.168.17.47 Network: Only a switch between them - the subnet is 192.168.16/22 (In this test, I also have dummynet filtering simulating an 80ms ping time on all IP traffic. I've seen nearly identical traces with a "real" setup, with real internet traffic/latency also) Questions: Does this look normal? Is packet #2 specifying a window size of 65535 and a scale of 512? Is packet #5 then shrinking the window size so it can use the 512 scale and still keep the overall calculated window size near 64K? Why is the window scale so high? Here are the first 6 packets from wireshark. For packets 5 and 6 I've included the details showing the window size and scaling factor being used for the data transfer.

• Some URLs fail to load on Windows web portal

  - by jpolache

  I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

• How to install audio drivers for Acer Revo nettop?

  - by CT

  I have a Acer Revo nettop. I wiped the XP Home install that came on the machine and put XP Pro on. Acer's support website would lead you to believe that this product does not exist. I know it has a NVIDIA ION LE chipset so I headed over to nvidia.com to download drivers. Ive downloaded and installed the Chipset drivers, Graphics Drivers, and HDMI audio drivers. I have no sound. Under Device Manager there is an unknown Audio Device on High Definition Audio Bus. I do not have an HDMI cable to test hdmi audio. I would just like the standard audio mini-jack output to work. Anyone know of the correct driver or a generic driver that would work? Thanks

• Inconsistent black levels in windows 7 media center

  - by James G

  I've got a HTPC running windows 7 64bit, hooked up to a Samsung LCD TV. My problem is different types of video are displaying different black levels on the TV. When I play a bluray through Arcsoft Total Media Theater I have to set the "HDMI Black Level" to "normal" in the TV picture options menu. When I play recorded TV through WMC I have to set it to "low" otherwise the black colors on the video are washed out and grey. Is there any way to configure the system so all videos are displayed with the same black level? The hdmi black level setting is deep in Samsung's menus so it's becoming a chore to keep switching it everytime I watch a different type of video. I'm using an ATI 4670 graphics card with HDMI output going straight to the TV. In the ATI catalyst control center I've got pixel format set to RGB 4:4:4 (Full RGB) since the TV wont allow me to change the HDMI black level if I choose one of the other settings.

• My linux server takes more than an hour to boot. Suggestions?

  - by jamieb

  I am building a CentOS 5.4 system that boots off a compact flash card using a card reader that emulates an IDE drive. It literally takes about an hour to boot. The ultra-slow part occurs when Grub is loading the kernel. Once that's done, the rest of the boot process only takes about a minute to get to a login prompt. Does anyone have any suggestions? I suspect that it may have to do with UDMA. Everything IDE-related in my BIOS seems to checkout. The read performance hdparm is telling me 1.77 MB/s. Ouch! (But even at that rate, it still shouldn't take an hour to decompress and load the kernel) [root@server ~]# hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 2444 MB in 2.00 seconds = 1222.04 MB/sec Timing buffered disk reads: 6 MB in 3.39 seconds = 1.77 MB/sec Trying to enable DMA is a no-go though: [root@server ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Here's some command outputs that might help: System [root@server ~]# uname -a Linux server.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux PCI info: [root@server ~]# lspci -v 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) Subsystem: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation 82945G/GZ Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ff00 [size=8] Memory at d0000000 (32-bit, prefetchable) [size=256M] Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 Flags: bus master, medium devsel, latency 0, IRQ 16 I/O ports at fe00 [size=32] 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 Flags: bus master, medium devsel, latency 0, IRQ 17 I/O ports at fd00 [size=32] 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 Flags: bus master, medium devsel, latency 0, IRQ 18 I/O ports at fc00 [size=32] 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 Flags: bus master, medium devsel, latency 0, IRQ 19 I/O ports at fb00 [size=32] 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at fdfff000 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fde00000-fdefffff Prefetchable memory behind bridge: 00000000fdd00000-00000000fdd00000 Capabilities: [50] #0d [0000] 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) Subsystem: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge Flags: bus master, medium devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 80 [Master]) Subsystem: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at f800 [size=16] Capabilities: [70] Power Management version 2 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) Subsystem: Intel Corporation 82801G (ICH7 Family) SMBus Controller Flags: medium devsel, IRQ 17 I/O ports at 0500 [size=32] 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• SCM8014 to FVS338

  - by Jack

  I have a SMC8014 Router/Modem that Comcast provided me with their business class service. It was not filtering malicious traffic as aggressively as I had hoped, so I purchased a NetGear ProSafe FVS338, and put this behind the SMC8014, and all my machines behind that. After some brief configuration, all machines can see out to the internet. I also have a single web server, and I have not been able to configure things so that incoming requests can reach it. This is where I need help! I would like to have the FVS339 do NAT, so that I can assign a 192.168 address to my webserver. I've tried everything I know of, and I can't get things going. I set the SMC8014 to have a LAN facing IP of 10.0.0.1, and I assigned the FVS339 a WAN facing IP of 10.0.0.2. I would like to be able to tell the SMC8014 to just forward all traffic to 10.0.0.2, but I haven't had any success. In my (unfortunately limited) understanding, what I probably want here is a static route, but I don't know how to cofigure one, or if this is really what I want. The SMC8014 wants a Destination IP, a Subnet Mask and a Gateway IP. Any help would be appreciated.

• Display won't come back from power saver mode

  - by tynor

  I wan't sure where exactly to post this question, but this one seemed the most relevant. I have a Dell LCD monitor running off a Dell Inspiron 531 tower with an Nvidia GeForce 8600 GT video card. Just recently, when I turn my computer on, the display immediately enters its "Power Saver" mode, and never wakes up. This problem doesn't occur with other computers, or even with this same computer when I use the integrated graphics. I have no other displays to test the card on. I have also tried replacing the power supply (my original one, which ran that video card for 4 years, was 300w, and I replaced it with 500w). Is there anything else I can try to troubleshoot this issue?

• Wrong PC-projector resolution in Windows 7

  - by peter.olsson

  I'm connecting a PC-projector (Benq MP721) to a Windows 7 Professional laptop (HP 6730b). All the output settings on the laptop, including the laptop screen, changes to 1024x768 (which the projector supports). However the projector says it receives 1360x768 and asks me to change the resolution to 1024x768. I'm using mirrored display. The laptop is 1024x768 The screen resolution in the control panel says 1024x768 The Intel graphics card utilities says 1024x768 The driver for the projector is a Generic PnP Monitor Is there anything in Windows 7 that would convert my 4:3 resolution to wide screen automatically?

• Common Mercator Projection formulas for Google Maps not working correctly

  - by Tom Halladay

  I am building a Tile Overlay server for Google maps in C#, and have found a few different code examples for calculating Y from Latitude. After getting them to work in general, I started to notice certain cases where the overlays were not lining up properly. To test this, I made a test harness to compare Google Map's Mercator LatToY conversion against the formulas I found online. As you can see below, they do not match in certain cases. Case #1 Zoomed Out: The problem is most evident when zoomed out. Up close, the problem is barely visible. Case #2 Point Proximity to Top & Bottom of viewing bounds: The problem is worse in the middle of the viewing bounds, and gets better towards the edges. This behavior can negate the behavior of Case #1 The Test: I created a google maps page to display red lines using the Google Map API's built in Mercator conversion, and overlay this with an image using the reference code for doing Mercator conversion.

• Windows 7 Via Hyperion 4-1 drivers

  - by Gratzy

  I have a clean install of Win 7 on some relatively old hardware. Everything works pretty well however my cpu is pegged at 100% most of the time. Task Manager shows srvchost as being a main culprit of course but also system interrupts. I have a Biostar socket 478 MB with Via chipset. I have tried to find Windows 7 drivers for this but when I download and try to install what VIA/BIOSTAR say should be good for all OS's it will not load. I get a message saying can't find components for this OS. Anybody have any idea where I might find suitable drivers for the Chipset? BTW I'm not using the integrated graphics on the board but have a radeon 4500 pci-e card.

• How to remap IPs visible from local machine to IPs visible from a machine I have SSH access to?

  - by gooli

  I'm so far out of my depth I don't even know what to google for. There's a server I can connect to via SSH. Via that server I can access other server on its subnet via SSH. What I want to do is be able to access the machines that server has access to directly. Say the server IP is 192.168.7.7 and is the only one in the 192.168.x.x range I have access to. I'd like to configure things in such a way that when I to access say 192.168.7.100 on my machine, the connection will go through an SSH tunnel I open to 192.168.7.7 and out to 192.168.7.100. I would like this to work for any port if at all possible. I know I can set an HTTP proxy and even a SOCKS proxy, but I'm wondering is there is a way to actually remap some of the IP my machine sees to IP only visible from the remote machine. What would this configuration be called? IS this NAT, VPN, IP2IP or something else? How can I set up this on a Windows client box that connects via SSH to a Linux box? Sounds to me like I need to set up some kind of filtering on the network driver or possibly a virtual NIC, but I'm not sure where to go next.

• Performance required to improve Windows Experience Index?

  - by Ian Boyd

  Is there a guide on the metrics required to obtain a certain Windows Experience Index? A Microsoft guy said in January 2009: On the matter of transparency, it is indeed our plan to disclose in great detail how the scores are calculated, what the tests attempt to measure, why, and how they map to realistic scenarios and usage patterns. Has that amount of transparency happened? Is there a technet article somewhere? If my score was limited by my Memory subscore of 5.9. A nieve person would suggest: Buy a faster RAM Which is wrong of course. From the Windows help: If your computer has a 64-bit central processing unit (CPU) and 4 gigabytes (GB) or less random access memory (RAM), then the Memory (RAM) subscore for your computer will have a maximum of 5.9. You can buy the fastest, overclocked, liquid-cooled, DDR5 RAM on the planet; you'll still have a maximum Memory subscore of 5.9. So in general the knee-jerk advice "buy better stuff" is not helpful. What i am looking for is attributes required to achieve a certain score, or move beyond a current limitation. The information i've been able to compile so far, chiefly from 3 Windows blog entries, and an article: Memory subscore Score Conditions ======= ================================ 1.0 < 256 MB 2.0 < 500 MB 2.9 <= 512 MB 3.5 < 704 MB 3.9 < 944 MB 4.5 <= 1.5 GB 5.9 < 4.0GB-64MB on a 64-bit OS Windows Vista highest score 7.9 Windows 7 highest score Graphics Subscore Score Conditions ======= ====================== 1.0 doesn't support DX9 1.9 doesn't support WDDM 4.9 does not support Pixel Shader 3.0 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 7.9 Windows 7 highest score Gaming graphics subscore Score Result ======= ============================= 1.0 doesn't support D3D 2.0 supports D3D9, DX9 and WDDM 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 6.0-6.9 good framerates (e.g. 40-50fps) at normal resoltuions (e.g. 1280x1024) 7.0-7.9 even higher framerates at even higher resolutions 7.9 Windows 7 highest score Processor subscore Score Conditions ======= ========================================================================== 5.9 Windows Vista highest score 6.0-6.9 many quad core processors will be able to score in the high 6 low 7 ranges 7.0+ many quad core processors will be able to score in the high 6 low 7 ranges 7.9 8-core systems will be able to approach 8.9 Windows 7 highest score Primary hard disk subscore (note) Score Conditions ======= ======================================== 1.9 Limit for pathological drives that stop responding when pending writes 2.0 Limit for pathological drives that stop responding when pending writes 2.9 Limit for pathological drives that stop responding when pending writes 3.0 Limit for pathological drives that stop responding when pending writes 5.9 highest you're likely to see without SSD Windows Vista highest score 7.9 Windows 7 highest score Bonus Chatter You can find your WEI detailed test results in: C:\Windows\Performance\WinSAT\DataStore e.g. 2011-11-06 01.00.19.482 Disk.Assessment (Recent).WinSAT.xml <WinSAT> <WinSPR> <DiskScore>5.9</DiskScore> </WinSPR> <Metrics> <DiskMetrics> <AvgThroughput units="MB/s" score="6.4" ioSize="65536" kind="Sequential Read">89.95188</AvgThroughput> <AvgThroughput units="MB/s" score="4.0" ioSize="16384" kind="Random Read">1.58000</AvgThroughput> <Responsiveness Reason="UnableToAssess" Kind="Cap">TRUE</Responsiveness> </DiskMetrics> </Metrics> </WinSAT> Pre-emptive snarky comment: "WEI is useless, it has no relation to reality" Fine, how do i increase my hard-drive's random I/O throughput?

• How can I terminate wisptis.exe in Windows XP SP2

  - by user9950

  I am working in a production environment. Basically I work on graphics oriented enviroment so I used to work on catia and windchill as well. When I am opening a part or diagram in Catia along with CNEXT .exe (catia service) wisptis.exe is starting and making the system halt and Catia will crash. So I need to restart the worksation or I need to close all applications then I need to open catia then again the same problem. So please tell me how to avoid this or stop the wisptis.exe service. If I want to work on catia I need to kill wisptis.exe service otherwise I cant work.

• HTB.init / tc behind NAT

  - by Ben K.

  I have an Ubuntu 10 box that I'm trying to set up as a bandwidth-shaping router. The machine has one WAN interface, eth0 and two LAN interfaces, eth1 and eth2. NAT is configured using MASQUERADE as described at InternetConnectionSharing. I'm mostly concerned with shaping outbound traffic from the LAN interfaces -- in the end, I'd like to end up with a hard 768Kbps limit per-LAN-interface (rather than a limit on eth0 pooled across all interfaces). I installed HTB.init, and riffing on the examples, tried to set this up on eth1 by putting three files into /etc/sysconfig/htb: /etc/sysconfig/htb/eth1 DEFAULT=30 R2Q=100 /etc/sysconfig/htb/eth1-2.root RATE=768Kbps BURST=15k /etc/sysconfig/htb/eth1-2:30.dfl RATE=768Kbps CEIL=788Kbps BURST=15k LEAF=sfq I can /etc/init.d/htb start and /etc/init.d/htb stats and see information that /seems/ to suggest it's working...but when I try pulling a large file via the WAN interface the shaping clearly isn't in effect. Any suggestions? My guess is it has something to do with where the shaping falls in the NAT chain, but I really have no idea where to begin troubleshooting this. ---- Update: Here's my /etc/init.d/htb list output, it seems to make sense -- the default rate for eth1 is 768Kbps? ### eth0: queueing disciplines qdisc htb 1: root refcnt 2 r2q 100 default 30 direct_packets_stat 0 qdisc sfq 30: parent 1:30 limit 127p quantum 1514b perturb 10sec ### eth0: traffic classes class htb 1:2 root rate 768000bit ceil 768000bit burst 1599b cburst 1599b class htb 1:30 parent 1:2 leaf 30: prio 0 rate 6144Kbit ceil 6144Kbit burst 15Kb cburst 1598b ### eth0: filtering rules filter parent 1: protocol ip pref 100 u32 filter parent 1: protocol ip pref 100 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 100 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:30 match 00000000/00000000 at 12 match 00000000/00000000 at 16 ### eth1: queueing disciplines qdisc htb 1: root refcnt 2 r2q 100 default 30 direct_packets_stat 0 qdisc sfq 30: parent 1:30 limit 127p quantum 1514b perturb 10sec ### eth1: traffic classes class htb 1:2 root rate 768000bit ceil 768000bit burst 1599b cburst 1599b class htb 1:30 parent 1:2 leaf 30: prio 0 rate 6144Kbit ceil 6144Kbit burst 15Kb cburst 1598b

• Disable laptop's display on boot when used with external display

  - by Ryan

  I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.) The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising. Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?

• CryptSvc not matched by Windows 7 Firewall rule

  - by theultramage

  I am using Windows Firewall in conjunction with a third-party tool to get notified about new outbound connection attempts (Windows Firewall Notifier or Windows Firewall Control). The way these tools do it is by setting the firewall to deny by default, and to add an auditing policy to log blocked connections into the Security event log. Then they watch the log, and display notification about newly added entries. netsh advfirewall set allprofiles firewallpolicy blockinbound,blockoutbound auditpol /set /subcategory:{0CCE9226-69AE-11D9-BED3-505054503030} /failure:enable With this configuration in place, I now need to craft outbound allow rules for applications and system services. Here is the rule for CryptSvc, the service frequently used for certificate validation and revocation checking: netsh advfirewall firewall add rule name="Windows Cryptographic Services" action=allow enable=yes profile=any program="%SystemRoot%\system32\svchost.exe" service="CryptSvc" dir=out protocol=tcp remoteport=80,443 The problem is, this rule does not work. Unless I change the scope to "all programs and services" (which is really unhealthy), connection denied events like the following will keep appearing in the security log: Event 5157, Microsoft Windows security auditing. The Windows Filtering Platform has blocked a connection. Application Information: Process ID: 1476 (<- svchost.exe with CryptSvc and nothing else) Application Name: \device\harddiskvolume1\windows\system32\svchost.exe Network Information: Direction: Outbound Source Address: 192.168.0.1 Source Port: 49616 Destination Address: 2.16.52.16 Destination Port: 80 Protocol: 6 (<- TCP) To make sure it's CryptSvc, I have let the connection through and reviewed its traffic; I also configured CryptSvc to run in its own svchost instance to make it more obvious: ;sc config CryptSvc type= share sc config CryptSvc type= own So... why is it not matching the firewall rule, and how to fix that?

• Need Recommendations: Network Software and Hardware Setup for small firm

  - by Rogue

  Will be starting a small graphics design firm soon, with 20 employees. Therefore need software to manage the network. Have bought a bulk license of Windows 7. I have a spare computer which can act as a server if necessary, but its an ancient Dell machine (Pentium-III). If required I would purchase an extra machine, but would like to avoid unnecessary costs at start up. Following are the main functions that I would like to perform: Need to monitor\control network traffic and internet usage, restrict access to certain websites Alerts when access to certain software's, and when trying to tamper with privileges Ability to view desktops of any computer at any given time Limit access to certain hardware like USB ports,etc Limit access to folders on the computer Log/Report of all actions including keystrokes performed on any computer Local Network chat and talk client Collaboration and Work logs Any Software available to do all of the above and also any additional hardware required besides network switches, network card's and CAT5e cables. Any other recommendations besides the above mentioned hardware setup
