• in HFT trading should I upgrade from Windows Server 2008 R2 to Windows Server 2012?

  - by javapowered

  I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012. I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency http://msdn.microsoft.com/library/windows/hardware/jj248719 http://technet.microsoft.com/en-us/library/hh831415.aspx Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2. So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?

• Error starting nginx and passenger 3 for Rails app on Suse Linux

  - by thesis

  I have configured passenger on SuSe Linux using simple configuration procedure (calling passenger command and then installing all libraries wich are needed), but now it throws an error.. Is there any solutions how to fix it? test@linux-p1g4:~/test_app/myapp> passenger start *** ERROR *** Could not start Passenger Nginx core: [alert]: could not open error log file: open() "/tmp/passenger-standalone.22737/logs/error.log" failed (2: No such file or directory) [alert]: Unable to start the Phusion Passenger watchdog because its executable (/var/lib/passenger-standalone/3.0.2-x86_64-ruby1.8.7-linux-gcc4.5.0-1002/suppor t/agents/PassengerWatchdog) does not exist. This probably means that your Phusion Passenger installation is broken or incomplete, or that your 'passenger_root' directive is set to the wrong value.

• Can you authenticate into SSAS with AD LDS (ADAM) accounts?

  - by Jaxidian

  I'm very new to AD LDS and experienced but not qualified with SSAS, so my apologies for my ignorances with these. We have a couple implementations where we expose SSAS via an HTTPS proxy (msmdpump.dll) and currently we have a temporary domain setup handling this (where our end-users have a second account+creds to manage because of this = non-ideal). I want to move us towards a more permanent solution which I'm thinking of moving all authentication to AD LDS for our web apps, SSAS, and others. However, SSAS is where I'm concerned about this. I know SSAS requires Windows Authentication and to play nicely, and that this ultimately means Active Directory will be involved. Is there a way to get this done with AD LDS instead of having to use a full AD DS implementation? If so, how? (Note: My question over at StackOverflow had a suggestion that I post this question here on ServerFault instead. My apologies if I'm not asking in the right forum.)

• Link rate between EMC DAE and HBA

  - by Johan Christensson

  I have a EMC DAE (KTN-STL4) drive cage directly connecconnected to a HP Proliant server using a QLogic QLE2560 HBA. I'm using copper cable between the HBA card and the DAE. On the controller card in the DAE there is a label that states "4Gb". I'm guessing that this means 4Gbit/s. But if I set the HBA card to "Auto speed" it negotiate 2Gbit/s, and if I hard set it to 4Gbit/s I end up with no link. Why is this? Isn't the DAE controller card capebel of link speed higher then 2Gbit/s or is it the copper cable that limits the speed, or is it the interface used between the DAE and Qlogic HBA that is the problem? I have been browsing for HSSDC-FC converters and they always seems to på rated at ~2Gbit/s. If this is the limit, why does it say 4Gb on the controller cards in the DAE?

• can I bundle multiple installs for Mac OSX and do them as a single script?

  - by Dov

  I have a lot of open source software to be installed for a course. We currently run on PCs that we provide. If we allow students to use their own Macs in Mac-centric schools, that means we have to load the software on those Macs. Rathern than have to load individual software, is there any way I can create a single file, mount it and run a script to install all packages? We are willing to simplify the installs by standardizing the locations to store the applications, since the students will have identical machines.

• Can we have Linked Servers when using NTLM?

  - by BlueRaja

  I don't have access to the Active Directory settings, nor do I have access to change anything on the linked server. From everything I've read, it seems like this means I cannot use Kerberos - which is a big problem, because I don't know how to use a linked server without it. Is there any way to connect to a linked server without Kerberos? Exact problem description When I connect to the linked server while sitting in front of my server, it works fine; but when I try to connect to the linked server from any other computer (delegating through my server), it gives the error: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. (Microsoft SQL Server, Error: 18456) It seems that this is the "double-hop problem," and the usual solution is to enable Kerberos, which requires access to AD and the linked server. I get the same error when I set security to "Be made using the login's current security context," and I can't use "Be made using this security context" because that appears to use SQL-authentication (which is not enabled on the linked server) instead of NTLM

• UDP multicast streaming of media content over WIFI

  - by sajad

  I am using vlc to stream media content over wireless network in scenario like this (from content streamer to stream receiver client): The bandwidth of wireless network is 54 Mb/s and UDP stream's required bandwidth is only 4 Mb/s; however there is trouble in receiving media stream and quality of playing specifically in multicast mode; means I can play the stream but it has jitter and does not play smoothly. In uni-cast I can stream up to 5 media streams correctly, but in multicast mode there is problem with streaming just one media! However when I stream from client some multicast streams; the wifi access-point can receive data correctly and I can see the video in "udp streamer" side correctly even when number of multicast streams increases to 9; But as you see I want to stream from streaming server and receive media in client size. Is this a typical problem of streaming real-time contents over wireless networks? Is it necessary to change configurations of my WIFI switch or it is just a software trouble? thank you

• Exchange 2003 Outlook Anywhere - Changed certificate, not working

  - by JohnyD

  I have a single Exchange 2003 installation which for the past 2 years has been set up for Outlook Anywhere access by means of a self-signed certificate. Just this past week I updated that certificate to a Go Daddy wildcard certificate to allow for use of our web services over https. I've updated the web listener on our ISA 2006 firewall and I can successfully use our services over https. However, my Outlook Anywhere access is now not functioning. I've installed the new wildcard certificate on my XP notebook into the Trusted Root Certificate Store but I keep getting prompted that the password is incorrect. To make things even more confusing I also have OWA set up and this works fine with the new certificate. Any ideas as to what I'm doing wrong?

• nginx stop/reload on windows failed for Access is denied

  - by TN.

  I am running nginx on Windows Server 2008 R2 (x64) as a windows service. I am using Windows Service Wrapper for that. (Actually, I have followed this tutorial: http://mercurial.selenic.com/wiki/HgServeNginxWindows.) The service is running ok. However, the server does not process the signals (e.g. stop / reload). This means if I stop the service, nginx is not stopped. (I have to kill it.) And when I want to reload the configuration from command line: C:\Users\Administrator>E:\apath\nginx\nginx.exe -p E:\apath\nginx -c E:\apath\nginx.conf -s reload It outputs: nginx: [error] OpenEvent("Global\ngx_reload_4268") failed (5: Access is denied) I am running the command as administrator and the service is running under NETWORK SERVICE user. Any hints or similar issues?

• Using a secondary DNS when lookup fails in primary? [migrated]

  - by Huckle

  I use a VPN to connect my development machine to my school's CS dept. The development machine is Ubuntu as we do C programming in Unix. I used vpnc to do that. The school uses some DNS entries that only resolve on their DNS servers, i.e., internalserver.csdept.school.edu I am normally attached to the VPN whenever booted for convenience. However I noticed the other day that when I disconnect the VPN all my DNS queries fail. This obviously means that vpnc set up the school's DNS to be used. However I'd rather not use their DNS all the time (tracking and privacy and whatnot). Is there a way I can restore my ISP's DNS and then if the lookup fails, have it use my school's DNS?

• Mapping Left Alt key in vim?

  - by Yogesh Arora

  I am able to map the key combination Right Alt+Left Arrow with <a-left> or by <m-left>. But I am not able to map the Left Alt key. Is there a way to do that? Edit: Just to clarity <a-left> means Alt+Left Arrow. The important question here is what is difference between Left Alt and Right Alt from the perspective of keymappings in Vim?

• Mini DisplayPort to DVI-D Dual Link up to 2560 * 1600

  - by Steinway Wu

  I have a ThinkPad T530 with Mini DP++ and NVS 5400M, which are said to support 2560 * 1600 resolution. The display is Dell 3007WFP, which also supports 2560 * 1600. But, I have never seen any cables or adapters that can connect them with full support to 2560 * 1600. Do you have any idea? THANK YOU! In addition, I found that mDP++ means I can use a passive adapter. No need for active adapter which is much more expensive. This is the only one that meets my needs, but it is not sold in the US. And this one seems to be OK, but I am not sure because it says "2.5 Gbps per channel", which may not be enough.

• Linux Virtualization Options on EC2

  - by recampbell

  I need to subdivide EC2 (or perhaps other cloud provider) instances. I know you cannot run a full virtualization stack on another. For instance a Xen guest cannot host a VirtualBox guest. So this means I am left with operating system-level virtualization. EC2 kernels are only publishable by select vendors, so you cannot upload the custom kernels required for OpenVZ or Vserver. For Linux, I think this leaves me with lxc (on Ubuntu 9.10), User Mode Linux, or qemu. I'm having a hard time finding comparisons between them. Performance is a concern, as is the ability to provide SMP to the guests. I would also like to use COW/sparse roots to reduce guest provisioning. My question is, what are the trade-offs between these options?

• Can't copy files with 'additional permissions' to ext4 drive -- files that have @ after permissions,

  - by 99miles

  I am copying files from Snow Leopard to a mounted ext4 share via Samba, that's on a Fedora machine. Some files cannot be copied, and give this error: The operation can’t be completed because you don’t have permission to access some of the items. I've noticed that the files that can't be copied have an @ at the end of their permissions whien I do 'ls -l' in the command line. For example, I can copy the second file but not the first: -rwxrwxrwx@ 1 miles staff 1448 May 14 22:55 test.txt -rw-r--r-- 1 miles staff 136 Apr 5 17:06 image.psd.zip From what I've found, the @ means the file has 'additional properties'. Does anyone know how I can resolve this issue so I can copy the files to the fileshare?? Thanks!

• my Website loss packet in 70% countries, how can i dertermine why its loss packets?

  - by user2511667

  I checked my website on google page speed tester, it show result 90/100. I checked my website on pingdom it shows good result there. When i check my website in cloudmonitor.ca.com, it shows good result in 30% countries and all other countries it show packet loss (100%) How we can determine why my website has packet loss? And what is its solution? Is this problem from my server or from my website? I created new html blank page and set it too my index page, after I tested, it still shows packet loss, guess this means the problem is not in my website. Here is live result When I visit my website in browser, website is working fine. But when i test my domain or IP 198.178.123.219 in command Prompt it shows "Request time out" Why time out in command prompt?

• Nexenta/OpenSolaris filer kernel panic/crash

  - by ewwhite

  I've an x4540 Sun storage server running NexentaStor Enterprise. It's serving NFS over 10GbE CX4 for several VMWare vSphere hosts. There are 30 virtual machines running. For the past few weeks, I've had random crashes spaced 10-14 days apart. This system used to open OpenSolaris and was stable in that arrangement. The crashes trigger the automated system recovery feature on the hardware, forcing a hard system reset. Here's the output from mdb debugger: panic[cpu5]/thread=ffffff003fefbc60: Deadlock: cycle in blocking chain ffffff003fefb570 genunix:turnstile_block+795 () ffffff003fefb5d0 unix:mutex_vector_enter+261 () ffffff003fefb630 zfs:dbuf_find+5d () ffffff003fefb6c0 zfs:dbuf_hold_impl+59 () ffffff003fefb700 zfs:dbuf_hold+2e () ffffff003fefb780 zfs:dmu_buf_hold+8e () ffffff003fefb820 zfs:zap_lockdir+6d () ffffff003fefb8b0 zfs:zap_update+5b () ffffff003fefb930 zfs:zap_increment+9b () ffffff003fefb9b0 zfs:zap_increment_int+68 () ffffff003fefba10 zfs:do_userquota_update+8a () ffffff003fefba70 zfs:dmu_objset_do_userquota_updates+de () ffffff003fefbaf0 zfs:dsl_pool_sync+112 () ffffff003fefbba0 zfs:spa_sync+37b () ffffff003fefbc40 zfs:txg_sync_thread+247 () ffffff003fefbc50 unix:thread_start+8 () Any ideas what this means?

• IIS: redirect to a webpage if authentication fails

  - by DrStalker

  We have an IIS site (MOSS 2007) that uses Windows Authentication. When a user that has forgotten their password tries to login the servers keeps sending 401 requests. This means on IE the user gets three prompts before IE displays a blank page, on Firefox the user is prompted over and over until they give up. We would like to change the behavior so if a user fails to login three times in a row we send them a redirect to a different site, instead of another 401 Forms authentication is not an option; the site has to remain on windows authentication to allow for SSO capabilities and certain sharepoint functions. Is there any way to tweak the IIS behavior to do this?

• MacBook Pro Boot Camp SPDIF passthrough?

  - by Ryan Zink

  I'm using Windows 7 through Boot Camp on a unibody Macbook Pro and am having problems using the SPDIF output. I get the expected Dolby Digital or DTS in some movies, but in other movies and in games (Source engine, StarCraft 2) where the output is enabled to 5.1, the output invariably shows up as Dolby Pro Logic, which means (I think) that passthrough is not enabled. The boot camp drivers for the sound card don't have any sort of control panel, and the Windows settings for enabling DTS and Dolby seem to work when I test those outputs in the sound settings. Is there some other setting or utility I can use to enable SPDIF passthrough for all programs?

• "Supervising" syslog-ng in htop

  - by djechelon

  Hello, I was working at my server, when in htop I just noticed something unusual. The syslog-ng process was listed as follows supervising syslog-ng /sbin/syslog-ng I don't know what it means. I tried to do man supervising but found nothing. supervising command doesn't exist too. Googling, I found a page about launchtool, but I can't find neither it or its man page in my system. I'm curious What does that executable/command/whatever do? Why today did I read that line in htop? Thank you. PS: I was unsure about posting this to SU or SF: even if it's a server-related question, it covers general Linux.

• How is the "change password at next logon" requirement supposed to work with RDP using Network Level Authentication?

  - by NReilingh

  We have a Windows server (2008 R2) with the "Remote Desktop Services" feature installed and no Active Directory domain. Remote desktop is set up to "Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)". This means that before the remote screen is displayed, the connection is authenticated in a "Windows Security: Enter your credentials" window. The only two role services installed on this server is the RD Session Host and Licensing. When the "User must change password at next logon" checkbox is selected in the properties for a local user on this server, the following displays on a client computer after attempting to connect using the credentials that were last valid: On some other servers using RDP for admin access (but without the Remote Desktop Services role installed), the behavior is different -- the session begins and the user is given a change password prompt on the remote screen. What do I need to do to replicate this behavior on the Remote Desktop Services server?

• Can't set-up Wifi Adhoc on my Raspberry Pi with an USB dongle

  - by Wouter

  I am trying to set-up an access point (ad-hoc) for my Raspberry Pi. That means I'm trying to "share" the ethernet connection over Wi-Fi. I am doing this using my Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter. When following a tutorial (or actually every tutorial), it immediately goes wrong. root@pinkypi:/home/pi# iwconfig wlan0 mode ad-hoc Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Device or resource busy. I already tried ifdown and not having it in the USB port at the startup. If it helps, every action with the thing fail (or at least setting the mode). I am using Debian. I'm sure I'm overseeing something, but I can't find out what. What is wrong?

• New Windows 7 Libraries created keep disappearing

  - by Sean

  I've just got a new laptop that came pre-installed with Windows 7 Professional edition. One of the new features of Windows 7 is Libraries. I'm familiar with how this works and am trying to create my own library called 'Work' to include all my work folders on my computer. However every time I create a new custom Library, after I rename it, it disappears from my Library menu. Each time I click Libraries in the Explorer, I keep seeing the same 4 default libraries, I.e. Documents, Pictures, Music, and Video. So when I try to create a new Library called 'Work' again, I get a pop up message "Do you want to rename New library to Work (2).Library-Microsoft?" Which means that my original work library still exists but for some reason I can't see it. Can someone please help me figure out why this is happening?
