  • SSH_ORIGINAL_ENVIRONMENT error with snow leopard client to a gitosis server on debian

    - by Mica
    I have a server running gitosis (installed from the package manager) on debian lenny. I am able to perform all operations from my linux mint laptop, but from my Mac running an up-to-date Snow Leopard gives me the following error: mica@waste Desktop$ git clone [email protected]:Poems.git Initialized empty Git repository in /Users/micas/Desktop/Poems/.git/ ERROR:gitosis.serve.main:Repository read access denied fatal: The remote end hung up unexpectedly mica@waste Desktop$ ssh -v [email protected] OpenSSH_5.2p1, OpenSSL 0.9.8l 5 Nov 2009 debug1: Reading configuration data /etc/ssh_config debug1: Applying options for * debug1: Connecting to 192.168.0.156 [192.168.0.156] port 22. debug1: Connection established. debug1: identity file /Users/micas/.ssh/identity type -1 debug1: identity file /Users/micas/.ssh/id_rsa type 1 debug1: identity file /Users/micas/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5 debug1: match: OpenSSH_5.1p1 Debian-5 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '192.168.0.156' is known and matches the RSA host key. debug1: Found key in /Users/mica/.ssh/known_hosts:5 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering public key: /Users/mica/.ssh/id_rsa debug1: Remote: Forced command: gitosis-serve mica@waste debug1: Remote: Port forwarding disabled. debug1: Remote: X11 forwarding disabled. debug1: Remote: Agent forwarding disabled. debug1: Remote: Pty allocation disabled. debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Remote: Forced command: gitosis-serve micas@waste debug1: Remote: Port forwarding disabled. debug1: Remote: X11 forwarding disabled. debug1: Remote: Agent forwarding disabled. debug1: Remote: Pty allocation disabled. debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: Requesting authentication agent forwarding.

  • SAS Expanders vs Direct Attached (SAS)?

    - by jemmille
    I have a storage unit with 2 backplanes. One backplane holds 24 disks, one backplane holds 12 disks. Each backplane is independently connected to a SFF-8087 port (4 channel/12Gbit) to the raid card. Here is where my question really comes in. Can or how easily can a backplane be overloaded? All the disks in the machine are WD RE4 WD1003FBYX (black) drives that have average writes at 115MB/sec and average read of 125 MB/sec I know things would vary based on the raid or filesystem we put on top of that but it seems to be that a 24 disk backplane with only one SFF-8087 connector should be able to overload the bus to a point that might actually slow it down? Based on my math, if I had a RAID0 across all 24 disks and asked for a large file, I should, in theory should get 24*115 MB/sec wich translates to 22.08 GBit/sec of total throughput. Either I'm confused or this backplane is horribly designed, at least in a perfomance environment. I'm looking at switching to a model where each drive has it's own channel from the backplane (and new HBA's or raid card).

  • Installing Cygwin C and C++ compilers for NetBeans IDE 7.2

    - by user1294663
    I am very new to Cygwin, C, C++ and NetBeans IDE 7.2. My PC is running MICROSOFT WINDOWS 7 OS. I have read the documentation on how to install the Cygwin C C++ compilers. http://netbeans.org/community/releases/72/cpp-setup-instructions.html#compilers I have tried to run Cygwin setup.exe that has the most recent version of the Cygwin DLL is 1.7.16-1. I am not very sure which exact package to install when the Cygwin setup.exe installer prompted for the selection of packages to download and install. I want to install the Cygwin C and C++ compilers so that i can create C and C++ projects using NetBeans 7.2 I selected those packages that has contains the following names gcc, g++, gdb and make. Then i proceed on to install the selected packages The installation took up a long time so i stopped after about 45 minutes or so. I browsed the installation folder and i saw some packages i selected were installed. I noticed that some packages came in some sort of "zip" file with tar.gz extension. i added the folder path into the PATH variable in the windows 7 environment variables window. I think this command works C: cygcheck -c cygwin but the rest doesn't work i think. C: gcc --version C: g++ --version C: make --version C: gdb --version I tried to create the C C++ project using the Netbeans IDE 7.2 and the IDE pops out a dialog message saying that there was no c c++ compilers found. Have i made some mistake here? like installing the wrong packages or something else??? Are there packages shown in the Cygwin setup.exe installer that contains exact names and exact version that is compatible with NetBeans IDE 7.2?? This i am not too sure. Because i i think i didn't really see some required packages with exact names and versions. My question is : Which exact packages do i install using the Cygwin setup.exe installer so that i can create C & C++ projects using Netbeans IDE 7.2? and what other steps do i have to take note to ensure complete successful installation? do i have to wait all the selected required packages to be installed? I WOULD LIKE TO KNOW THE EXACT NAMES AND THE VERSIONS FOR THE REQUIRED PACKAGES (NAMES AND VERSIONS DISPLAYED IN THE CYGWIN SETUP.EXE INSTALLER WHEN PROMPTED) NEEEDED FOR C & C++ PROGRAMMING USING NETBEANS IDE 7.2??

  • Cannot exit X server, restart, shutdown or drop to tty when VGA monitor active

    - by terdon
    I have a strange problem. If I connect an external VGA monitor to my laptop, exiting the X environment in any way crashes the computer. For example, say I am working with my two monitors (the laptop's and one connected to my VGA port) active. Hitting Ctrl+Alt+F Key should take me down to a tty. What actually happens is that the VGA screen goes blank, as you would expect, but the laptop screen, although still on, shows nothing. I know the screen is on because it is slightly more illuminated than when it is off. When in this state, I can do nothing to regain access to the machine. I have tried: Ctrl+F Key (and even Ctrl+Alt+F Key, just in case) combinations and none seem to have any effect. Ctrl+Alt+Del : Nothing Magic SysRq key: Nothing Blindly typing my username and password and trying to reboot/shutdown or restart GDM or MDM: Nothing The only thing that works is a hard reset. The exact same behavior occurs when kiling the X server through Ctrl+Alt+Backspace, rebooting or shutdown. There is no difference if I reboot/shutdown/log out using the WM's graphical menu or if I use the shutdown or rebootcommands. It is also not WM-dependent. I have the same problem using Cinnamon, Gnome 3, MATE and xfce4. It is, however, VGA dependent. I have tried connecting another VGA monitor and have the same problem. I do not, however, have this problem if a screen is connected to the DisplayPort. It is, therefore, a VGA specific issue. To make things even stranger, this only occurs when both screens are active. If either the laptop screen or the VGA monitor is inactive the problem goes away. Finally, this problem arose when I installed the latest Linux Mint Debian (LMDE). It did not occur with the previous release of LMDE. I am not sure what has changed since I used the same kernel version in both releases (I had upgraded the kernel while on the previous release) and, I think, the same nvidia drivers. Oh, and yes, I have updated the nvidia driver. Hardware: Dell M4500 laptop CPU: Intel Core i7 RAM: 8GB Graphics: nVidia GT216 [Quadro FX 880M] Software: LMDE, kernel 3.2.0-2-amd64 Xorg: 1.11.4 nVidia kernel: 295.20-1+3.2.9-1 Possibly relevant files: /var/log/Xorg.0.log ~/.xsession-errors Does anyone have any ideas how to fix this? Thanks in advance for any help.

  • Hylafax / Capi4hylafax: faxgetty does not recognize number of lines

    - by Wrikken
    We've got a T.30 card, 30 working lines on it, but for some reason, if I add more then 30 faxes in the queue at any time (and we're busy enough at peak times that this happens a lot), faxgetty sends faxes to non-existent lines and they appear in the error queue as a 'busy' signal on the line, which results in a lot of failed faxes because the counter of max 3 tries increases rapidly. This is using faxgetty (USE_FAXGETTY="y" in /etc/default/hylafax). I've inherited this thing, so I'm not entirely sure how faxgetty is supposed to know the number of lines. However, if I alter the script to faxmodem (USE_FAXGETTY="n" in /etc/default/hylafax and manually enabling 30 modems), this behavior goes away (new faxes 'wait' for a line to be available before trying to send, so each try / fail is a valid one on a working line, majorly descreasing the amount of failed faxes. However, when researching this almost anyone talks about faxgetty being the preferred, more robust, method, and on top of that for some unexplained reason all FIFO's disappeared for some reason after several errorless hours with faxmodem, forcing a hylafax restart using faxgetty until we figured out why this faxmodem solution failed (which is another question, and somewhat out of scope here). Environment: Debian 2.6.26-2-amd64 capi4hylafax 1:01.03.00.99.svn.300-12 hylafax-client 2:4.4.4-10.1 hylafax-server 2:4.4.4-10.1 Config --hfaxd.conf-- LogFacility: daemon ServerTracing: 0x1ff --hyla.conf-- Host: localhost Verbose: No VRes: 196 TimeZone: local DialRules: "/etc/hylafax/dialrules.europe" --/etc/hylafax/config -- InternationalPrefix: 00 LongDistancePrefix: 0 AreaCode: 99999 CountryCode: 31 DialStringRules: "etc/dialrules.europe" ModemGroup: any:faxCAPI SendFaxCmd: "/usr/bin/wrapc2faxsend" --/etc/hylafax/config.faxCAPI -- SpoolDir: /var/spool/hylafax FaxRcvdCmd: /var/spool/hylafax/bin/faxrcvd PollRcvdCmd: /var/spool/hylafax/bin/pollrcvd FaxReceiveUser: uucp FaxReceiveGroup: dialout LogFile: /var/spool/hylafax/log/capi4hylafax #no, checking this log did not yield anything interesting LogTraceLevel: 4 LogFileMode: 0600 ModemGroup: any:faxCAPI #repeats of faxCAPI2 = faxCAPI30, with of course another devicename/local ident: { HylafaxDeviceName: faxCAPI RecvFileMode: 0600 FAXNumber: ****redacted**** LocalIdentifier: ****some-ident-per-device*** MaxConcurrentRecvs: 0 OutgoingController: 1 OutgoingMSN: SuppressMSN: 0 NumberPrefix: NumberPlusReplacer: "00" UseISDNFaxService: 0 RingingDuration: 0 { Controller: 1 AcceptSpeech: 0 UseDDI: 0 DDIOffset: DDILength: 0 IncomingDDIs: IncomingMSNs: AcceptGlobalCall: 1 } } So in short: How does faxgetty determine the number of lines available? (the man page isn't terribly revealing, and I can't find an appropriate setting in hylafax-config. And how can I get a capi4hylafax/hylafax setup which queues more faxes then lines are available correctly without immediately incrementing the fail count? We will not be receiving any faxes on this machine b.t.w. As I said, I've inherited this thing, so if there are important configuration options I'm not including, please let me know.

  • How can I simulate blocking RTMP over port 80 on Windows?

    - by Christian Nunciato
    It seems like this should be so simple, but since this isn't my area of expertise, I'm having a hell of a time figuring out how to do it. Basically, I have a Flash app and I'm connecting to a Flash Media Server to stream some content. The URL I'm using to do this, for example, looks like this: rtmp://someserver.com/some/path/mp3:somefile Everything works -- but that's sort of the problem. When I'm trying to do is simulate my users attempting to play back my media under more restrictive conditions than the ones I have here (i.e., none) -- namely being stuck behind firewalls or proxy servers that block access to RTMP streams. Flash, according to Adobe, is equipped to handle proxy servers and firewalls automatically, like so (from the docs): When you do not specify a port number in an RTMP address, Flash will attempt to connect to port 1935. If it fails it will then try to connect to port 443; if that fails, it will try port 80. [And if that fails, it will attempt to connect via RTMPT (i.e., HTTP tunneling) on port 80.] So no coding is required to access ports 1935, 443, or port 80 if you do not specify a port in the RTMP address. The problem I'm having is setting up a reliable environment in which to test that this behavior actually happens. I'm on a Windows machine, for example, so with Windows Firewall, I can block certain ports and protocols (1935, 443), but I don't want to block port 80, because the final fallback protocol (RTMPT) is supposed to run on port 80, and Windows Firewall only gives me enough granularity (as far as I know, anyway) to block "all outbound TCP traffic to remote port 80" -- that is, I can't, apparently, block "all outbound RTMP traffic to port 80" while leaving RTMPT traffic to port 80 unaffected. My understanding thus far is that I'll probably need to set up a proxy server to do this. Is this correct? Or is there a simpler way (on Win 7, at least) to filter out RTMP to 1935, RTMP to 443, RTMP to 80, but still allow RTMPT to 80 (where all four hostnames are identical)? And if I do have to set up a proxy server, what's the simplest way to go on Windows? I've set up WinProxy, which seems a bit janky but apparently works -- but then what I can't figure out is how to tell Windows to force all TCP traffic (including RTMP, RTMPT and HTTO) through this proxy server so I can turn around and reject the requests for RTMP. Any help would be hugely appreciated. This isn't my realm of expertise and I've alreasdy spent more time on it than I probably should. :)

  • Blank displays after inactivity, mouse cursor not showing up

    - by Mike Christiansen
    I have a Windows 7 Enterprise x86 machine that is exhibiting some strange problems. After some inactivity (it varies how long it takes), when I come back to my computer, both of my monitors are black. The monitors are on, with a black display. Moving the mouse and pressing keys on the keyboard do not work. This happens at least once a day. When I first encountered the issue, I performed a hard shutdown and restarted the computer. About 10% of the time when I did this, the resolutions on my monitors were messed up. The native resolution on the primary monitor is 1600x900, and the native on my secondary is 1440x900. None of the widescreen resolutions would be present in the display properties. I had 800x600, 1024x768, and 1280x1024. As a workaround to this issue, I've found that if I plug in my secondary monitor as the primary monitor, and leave the secondary unplugged, then Windows will start in 1024x768 on the secondary. Then, I can use Windows 7's "Detect" feature and it finds the 1440x900 resolution, and sets it. Then I have to connect the primary monitor to the secondary port and set it as the primary. Then I can switch the two cables, putting the primary into the primary, the secondary into the secondary. Then use the "Detect" feature again, and it finds the correct resolutions. Some time after performing the above, I discovered that when the screens were blanked, I could simply press "Control+Alt+Delete", type in my password, and everything comes up fine - except my mouse cursor. All applications and features work as intended, except there is no mouse cursor (the mouse actually works though...). I have the "Show location of pointer when I press CTRL key" option selected, so I can press CTRL and use my mouse as normal - but I have no actual cursor. When the computer is in this state, UAC is also not functional. Whenever a UAC prompt appears, the screens go black (the original symptoms) and I have to press Escape to exit UAC. Because of the above symptoms (the UAC black screen thing, etc) I beleive winlogon.exe may be the culprit. However, I have no idea how to fix it. I am unable to restart winlogon.exe due to the problems I am having with winlogon.exe (the UAC black screen) Looking for any ideas.... More information Windows 7 x86 Enterprise Domain environment (I have a secondary account with administrator rights) Dell Optiplex 960 Cannot perform "optional" windows updates due to an activation issue (I am testing a windows 7 image, and an activation infrastructure has not been created yet. However, this issue was happening before I was unable to perform windows update, and windows was up to date at the time Updated video card driver (as an attempt to fixing the resolution issue) Disabled all power saving options Please let me know what else you need to help me solve this issue! Thanks in advance, Mike

  • Further Performance Tuning on Medium SharePoint Farm?

    - by elorg
    I figured I would post this here, since it may be related more to the server configuration than the SharePoint configuration or a combination of both? I'm open for ideas to try, or even feedback on things that maybe have been configured incorrectly as far as performance is concerned. We have a medium MOSS 2007 install prepped and ready for receiving the WSS 2003 data to upgrade. The environment was originally architected by a previous coworker, and I have since added a few configuration modifications to assist with performance before we finally performed the install. When testing the new site collections & SharePoint install (no actual data yet), things seemed a bit slow. I had assumed that it was because I was accessing it remotely. Apparently the client is still experiencing this and it is unacceptably slow. 1 SQL Server running SQL Server 2008 2x SharePoint WFEs - hosting queries (no index) 1x SharePoint Index - hosting index (no queries) MOSS 2007 installed and patched up through December '09 on WFEs & Index All 4 servers are VMs, should have more than sufficient disk space & RAM (don't recall at the moment), and are running Windows Server 2008 - everything is 64-bit. The WFEs have Windows NLB configured, with a DNS name & IP for the NLB cluster. Single NIC on each server (virtual, since VMWare). The Index server is configured as a WFE (outside of the NLB cluster) so that it can index itself and replicate the indexes to the WFEs that will serve the queries. Everything is configured & working properly - it just takes a minute or two to load a page on the local LAN. The client is still using their old portal (we haven't started the migration/upgrade just yet) so there's virtually no data or users. We need to either further tune the configuration, or fix anything that may have been configured incorrectly which is causing this slowness? I've already reviewed & taken into account everything that I could find that was relevant before we even started the install. Does anyone have ideas or pointers? Perhaps there's something that I've missed?

  • Complete Active Directory redesign and GPO application

    - by Wolfgang Kuehne
    after much testing and hundreds of tries and hours invested I decided to consult you experts here. Overview: I want to apply some GPO to our users which will add some specific site to the Trusted Sites in Internet Explorer settings for all users. However, the more I try the more confusing the results become. The GPO is either applied to one group of users, or to another one. Finally, I came to the conclusion that this weird behavior is cause rather by the poor organization in Users and Groups in Active Directory. As such I want to kick the problem from the root: Redesign the Active Directory Users and Groups. Scenario: There is one Domain Controller, and we use Terminal Services (so there is a Terminal Server as well). Users usually log on to the Terminal Server using Remote Desktop to perform their daily tasks. I would classify the users in the following way: IT: Admins, Software Development Business: Administration, Management The current structure of the Active Directory Users and Groups is a result of the previous IT management. The company has used Small Business Server which has created multiple default user groups and containers. Unfortunately, the guys working before me have do no documentation at all. Now, as I inherit this structure I am in the no mans land. No idea which direction to head first. As you can see, the Active Directory User and Groups have become a bit confusing. There is no SBS anymore, but when migrating from SBS to the current Windows Server 2008 R2 environment the guys before me have simply copied the same structure. The real question: Where should I start cleaning from, ensuring that I won't break totally the current infrastructure? What is a nice organization for the scenario that I have explained above?

  • Force Finder to log in as Guest to a SMB share

    - by slhck
    I have a QNAP NAS that offers a few SMB shares. As I'm in a trusted environment, my shares are accessible as guest rather than with a combination of username and password. Problem Now, when I click the name of the device in Finder's sidebar, I get the black "Connection failed" bar, with the option "Connect as...". When I click that, I receive: I can however press ? + K and enter the server's name manually, which gets me to this window: Here, I have to select "guest". Now, I can select one of the shares to connect to, and I'm finally connected to the server. If I select it in the sidebar, I get a list of all shares available, because I'm connected as "guest", obviously: What I need Well, as soon as I unmount all shares, I have to go through the same procedure of manually logging in as "guest" again, which I find quite annoying. Is there any way I could get Finder (or the underlying SMB client) to know which credentials to use? Or should I look for the solution rather on the server side? (I know that other SMB shares seem to work fine in my network) Diagnostics The only thing I can get out of Console.app is: 5/15/11 7:36:40 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[200] SharePointBrowser::handleOpenCallBack returned 64 This message occurs when I click the name of the SMB server in the Finder sidebar.

  • Converting an EC2 AMI to vmdk image

    - by Reed G. Law
    I've come quite close to getting Amazon Linux to boot inside VirtualBox, thanks to this answer and these websites. A quick overview of the steps I've taken: Launch EC2 instance with Amazon Linux 2011.09 64-bit AMI dd the contents of the EBS volume over ssh to a local image file. Mount the image file as a loopback device and then to a local mount point. Create a new empty disk image file, partition with an offset for a bootloader, and create an ext4 filesystem. Mount the new image's partition and copy everything from the EC2 image. Install grub (using Ubuntu's grub-legacy-ec2 package, not grub2). Convert the image file to vmdk using qemu-img. Create a new VirtualBox VM with the vmdk. Now the VM boots, grub loads, and the kernel is found. But it fails when it tries to mount the root device: dracut Warning: No root device "block:/dev/xvda1" found dracut Warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line. dracut Warning: Signal caught! dracut Warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line. Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.35.14-107.1.39.amzn1.x86_64 #1 I have tried changing /boot/grub/menu.lst to find the root device by label and UUID, but nothing works. I'm guessing the xen kernel is not compatible with VirtualBox. The reasoning behind all this effort is to make a Vagrant box that is as close to possible as the production enviroment, so deploys can be tested locally. I know it's cheap to do test runs on EC2, but poor connectivity often ruins the experience. Plus it would be really nice to have a virtual machine with the production environment so that co-workers don't have to install everything under the sun just to get up and running with app development. If I were to try running a different kernel, what kernel could I get to be as close as possible to Amazon Linux 2011.09?

  • getUserPrincipal() in JCIFS / Lan-Manager authentitation level setting in Windows 2k8

    - by Chris
    I have to find out in which exact format JCIFS stores the user principal in the "getUserPrincipal()" property. Therefor i created a test Environment like this: Windows Server 2008 Domain Controller Domain named "MYDOMAIN" Many Testusers in Active Directory Tomcat Application Server with my Web Application (which simply reads the user Principal and displays its values). The user should be logged in to the web-application with SSO therefor i need the format that jcifs is using to store the user. (For example user@MYDOMAIN or MYDOMAIN\user...) I tested the Authentication with other SSO frameworks with Kerberos Method and it works as expected. I'm now trying to use SSO through the NTLMHttpFilter of JCIFS. When i try to login i get the following error message: jcifs.smb.SmbException: The parameter is incorrect. jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:541) jcifs.smb.SmbTransport.send(SmbTransport.java:641) jcifs.smb.SmbSession.sessionSetup(SmbSession.java:322) jcifs.smb.SmbSession.send(SmbSession.java:224) jcifs.smb.SmbTree.treeConnect(SmbTree.java:176) jcifs.smb.SmbSession.logon(SmbSession.java:153) jcifs.smb.SmbSession.logon(SmbSession.java:146) jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:189) jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:121) Regarding to the documentation i'm using to configure this, this is a know issue with the Group policy. It is stated there, that i have to change the Group policy "Networkaccess: lan-manager authentication level" to respond to NTLMv1 request. I have done this, but it's still not working. So what i also have to configure is the same policy on the client computer. I have to change the policy, so that the client computer sends NTLMv1. But it is always sending NTLMv2 tokens. The problem now is that i'm somehow not able to change this setting. (I already was before) because the dropdown box to choose the authentication method is "greyed out". edit: just to make this clear, this dialog is on the client-side in the "local-security policies" As you can see from this screenshot, the chosen method is "Only send NTLMv2 responses" which is the wrong setting and i'm pretty sure that this is causing the error above. My question is now, why can't i change this setting? Why is it greyd out?

  • Why does Ubuntu 9.10 hang during boot at "Booting processor 1 APIC 0x1 ip 0x6000"?

    - by BraeburnDev
    I recently installed a new copy of Ubuntu 9.10 (Kernel 2.6.31-14) on to my Hp Pavilion dv6t, so I can setup a Linux development environment. The install went flawlessly and I proceeded with Ubuntu's udate manager's long list of updates (292 in all). I also setup a swap file and activated a Nvidia 185 driver for the Nvidia 260m GPU on the machine. After all this was done I restarted the computer and booted into Ubuntu this time with a newer 2.6.31-19 Kernel which was installed from the update manager. During booth the computer hung at this point: Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013136] Performance Counters: Nehalem/Corei7 events, Intel PMU driver.

Hopefully this is enough information to go on. I should add that I'm still new to configuring and running a Linux OS although I know enough basic command line usage to do software development. This is my attempt to become more familiar with Linux and manage my own system. I'd like to get some insight on the nature of this system hang, what the problem is and how to resolve it. At this point I can scrap the install if I broke something, but my intuition says this is an issue with the kernel recognizing the correct hardware configuration for my system, or perhaps this is an issue with the APIC drivers managing Nehalem's new power management capabilities? Thanks for looking at this issue and providing feed back.

  • Trouble with Debian Lenny and Sphinx

    - by Ando
    I've very basic understanding of linux systems, but I've a server which was setup a while ago to host some web apps. Recently I decided to test out and implement Sphinx but unfortunately I cant get the install to work. I'm running a Debian Lenny distro and when I try to install sphinx it says - checking MySQL include files... configure: error: missing include files. ****************************************************************************** ERROR: cannot find MySQL include files. Check that you do have MySQL include files installed. The package name is typically 'mysql-devel'. If include files are installed on your system, but you are still getting this message, you should do one of the following: 1) either specify includes location explicitly, using --with-mysql-includes; 2) or specify MySQL installation root location explicitly, using --with-mysql; 3) or make sure that the path to 'mysql_config' program is listed in your PATH environment variable. To disable MySQL support, use --without-mysql option. ****************************************************************************** I do have mysql 5.1 installed but I can't find the include files, AND one more thing..

  • Web Service gets unavailable after several concurrent calls

    - by Roman
    We are testing GoDaddy Virtual Data Center and came to a very strange issue when our web site gets unavailable. GoDaddy Support keeps saying the issue is in our web server settings, but looking at the result of our tests I doubt it. TEST ENVIRONMENT Virtual DataCenter with Windows hosted at GoDaddy.com. All servers have Windows Server 2008 R2 Datacenter, IIS 7. Server One with IP address 10.1.0.4 Server Two with IP address 10.1.0.3 Both servers are in private network not visible from outside. Port Forward with IP address 50.62.13.174. Port Forward is assigned to Server One TEST DESCRIPTION JMeter is used as a Client App to simulate 30 concurrent users sending 100 SOAP requests each. Interval between requests is 1 second. Http link used for testing: http://50.62.13.174/v2/webservices.asmx TEST ONE Test is run from a computer in our office. After JMeter starts running test, almost immediately, the link above becomes unavailable in a browser. After test completion, the link is not available in a browser for about 5 more minutes. Remote Desktop is working well, so we can connect to Server One remotely. After about 5 minutes since test completion, the link becomes available in a browser again. TEST TWO Test is run from Server Two (that is part of our virtual data center). Test works very well, no visible delays in processing. The link is available in a browser all the time. TEST THREE Test is run from Server One using localhost. The result is the same as in TEST TWO - no issues. TEST FOUR We repeated TEST ONE from other computers that we have located in different countries, all with the same result as TEST ONE. CONCLUSION As the test works well from Server Two, but does not work from outside our virtual data center, we feel there are issues with the network or its capacity. The whole behaviour looks like out requests from outside get stuck somewhere before reaching our virtual data center. Has anybody had similar issues in the past? Are there chances that something is wrong with our server settings?

  • How to know the source of certain TCP traffic on AIX

    - by A.Rashad
    We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help?

  • Updating the $PATH for running an command through SSH with LDAP user account

    - by Guillaume Bodi
    Hi all, I am setting up a Mac OSX 1.6 server to host Git repositories. As such we need to push commits to the server through SSH. The server has only an admin account and uses a user list from a LDAP server. Now, since it is accessing the server through a non interactive shell, git operations are not able to complete since git executables are not in the default path. As the users are network users, they do not have a local home folder. So I cannot use a ~/.bashrc and the like solution. I browsed over several articles here and there but could not get it working in a nice and clean setup. Here are the infos on the methods I gathered so far: I could update the default PATH environment to include the git executables folder. However, I could not manage to do it successfully. Updating /etc/paths didn't change anything and since it's not an interactive shell, /etc/profile and /etc/bashrc are ignored. From the ssh manpage, I read that a BASH_ENV variable can be set to get an optional script to be executed. However I cannot figure how to set it system wide on the server. If it needs to be set up on the client machine, this is not an acceptable solution. If someone has some info on how it is supposed to be done, please, by all means! I can fix this problem by creating a .bashrc with PATH correction in the system root (since all network users would start here as they do not have home). But it just feels wrong. Additionally, if we do create a home folder for an user, then the git command would fail again. I can install a third party application to set up hooks on the login and then run a script creating a home directory with the necessary path corrections. This smells like a backyard tinkering and duct tape solution. I can install a small script on the server and ForceCommand the sshd to this script on login. This script will then look for a command to execute ($SSH_ORIGINAL_COMMAND) and trigger a login shell to run this command, or just trigger a regular login shell for an interactive session. The full details of this method can be found here: http://marc.info/?l=git&m=121378876831164 The last one is the best method I found so far. Any suggestions on how to deal with this properly?

  • Windows Server 2008 Migration - Did I miss something?

    - by DevNULL
    I'm running in to a few complications in my migration process. My main role has been a Linux / Sun administrator for 15 yrs so Windows server 2008 environment is a bit new to me, but understandable. Here's our situation and reason for migrating... We have a group of developers that develop VERY low-level software in Visual C with some inline assembler. All the workstations were separate from each other which cased consistency problems with development libraries, versions, etc... Our goal was to throw them all on to a Windows domain were we can control workstation installations, hot fixes (which can cause enormous problems), software versions, etc... All Development Workstations are running Windows XP x32 (sp3) and x64 (sp2) I running in to user permission problems and I was wondering maybe I missed one, tWO or a handful of things during my deployment. Here is what I have currently done: Installed and Activated Windows Server 2008 Added Roles for DNS and Active Directory Configured DNS with WINS for netbios name usage Added developers to AD and mapped their shared folders to their profile Added roles for IIS7 and configured the developers SVN Installed MySQL Enterprise Edition for development usage Not having a firm understanding of Group Policy I haven't delved deeply in to that realm yet. Problems I'm encountering: 1. When I configure any XP workstations to logon our domain, once a user uses their new AD login, everything goes well, except they have very restrictive permissions. (Eg: If a user opens any existing file, they don't have write access, except in their documents folder.) Since these guys are working on low system level events, they need to r/w all files. All I'm looking to restrict in software installations. Am I correct to assume that I can use WSUS to maintain the domains hot fixes and updates pushed to the workstations? I need to map a centralized shared development drive upon the users login. This is open to EVERYONE. Right now I have the users folders mapped upon login through their AD profile. But how do I map a share if I've already defined one within their profile in AD? Any responses would be very grateful. Do I have to configure and define a group policy for the domain users? Can I use Volume Mirroring to mirror / sync two drives on two separate servers or should I just script a rsync or MS Synctool? The drives simply store nightly system images.

  • Problem connecting to SSH in office network

    - by Jeune
    I have trouble connecting via SSH to a server whenever I am in the office. I get as far as being prompted for my password and then after that there's a long wait which always ends in a Write failed: Broken pipe This is only for connecting via SSH. I use svn to commit files to a repository hosted on the same server and there are no hitches. Furthermore, this only happens in our office. When I go the university or whenever I am at home or at the coffee shop I am able to connect seamlessly. There are no firewalls in our office. It's just a basic wireless router connected to a modem setup. It's the same setup I have at home and I guess the same setup in the coffee shop. What are the causes for a broken pipe and why does this phenomenon only happen when I try connect via SSH and not when I work with svn on the same server?

I didn't do anything but that's because there is no one in the office but me! Having said that, is it possible that it has something to do with the number of sessions an SSH server can handle? UPDATE 2011-14-07: I try to login via SSH through Putty on another machine running windows together with my current SSH session in Ubuntu and now it seems my SSH session in Ubuntu has been dropped. I can't type into the terminal. Is Putty the culprit now?

  • Why does NX Client for Windows silently closes after connection?

    - by pavel
    Hey! I connect remotely to my Ubuntu server from Vista machine. Now I need to run a GUI application on the server (Wireshark). So I decided to use FreeNX server/client to view Ubuntu GUI on Vista I have successfully installed FreeNX on Ubuntu and NX Client on Vista. I was following this guide Unfortunately, now I found myself stuck with the following problem. At the client, the !M logo window appears, but after a few seconds that window just closes, even without showing any error message. Guys, I'm really stuck, please help! Maybe I should have installed some graphical environment on the server? These are the details from NX client, it seems there are no errors. ----------------- Info: Display running with pid '7768' and handler '0x670d24'.

  • lacp, cicso 3550, 3560, help with configuration

    - by Flamewires
    Hey all this is a repost from a question I asked on the cisco forums but never got a useful reply. Hey I'm trying to convert the FreeBSD servers at work to dual-gig lagg links from regular gigabit links. Our production servers are on a 3560. I have a small test environment on a 3550. I have achieved fail-over, but am having troubles achieving the speed increase. All servers are running gig intel (em) cards. The configs for the servers are: BSDServer: #!/bin/sh #bring up both interfaces ifconfig em0 up media 1000baseTX mediaopt full-duplex ifconfig em1 up media 1000baseTX mediaopt full-duplex #create the lagg interface ifconfig lagg0 create #set lagg0's protocol to lacp, add both cards to the interface, #and assign it em1's ip/netmask ifconfig lagg0 laggproto lacp laggport em0 laggport em1 ***.***.***.*** netmask 255.255.255.0 The switches are configured as follows: #clear out old junk no int Po1 default int range GigabitEthernet 0/15 - 16 # config ports interface range GigabitEthernet 0/15 - 16 description lagg-test switchport duplex full speed 1000 switchport access vlan 192 spanning-tree portfast channel-group 1 mode active channel-protocol lacp **** switchport trunk encapsulation dot1q **** no shutdown exit interface Port-channel 1 description lagginterface switchport access vlan 192 exit port-channel load-balance src-mac end obviously change 1000's to 100's and GigabitEthernet to FastEthernet for the 3550's config, as that switch has 100Mbit speed ports. With this config on the 3550, I get failover and 92Mbits/sec speed on both links, simultaneously, connecting to 2 hosts.(tested with iperf) Success. However this is only with the "switchport trunk encapsulation dot1q" line. First, I do not understand why I need this, I thought it was only for connecting switches. Is there some other setting which this turns on that is actually responsible for the speed increase? Second, This config does not work on the 3560. I get failover, but not the speed increase. Speeds drop from gig/sec to 500Mbit/sec when I make 2 simultaneous connections to the server with or without the encapsulation line. I should mention that both switches are using source-mac load balancing. In my test I am using Iperf. I have the server(lagg box) setup as the server(iperf -s), and the client computers are client(iperf -c server-ip-address), so the source mac(and IP) are different for both connections. Any ideas/corrections/questions would be helpful, as the gig switches are what I actually need the lagg links on. Ask if you need more information.

  • Web application/ site service (like Google App Engine) for PHP/ MySQL and Postgres

    - by Simon
    I would like to find a service similar to Google App Engine for PHP/ MySQL/ Postgres sites/ applications. We host two different types of site. i). PHP/ Mysql/ Zend Framework <VirtualHost *:80> DocumentRoot "/home/websites/website.com/public" ServerName website.com # This should be omitted in the production environment SetEnv APPLICATION_ENV development <Directory "/home/websites/website.com/public"> Options Indexes MultiViews FollowSymLinks AllowOverride All Order allow,deny Allow from all RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] </Directory> </VirtualHost> ii). Matrix CMS - PHP/ Postgres + loads of pear classes <VirtualHost *:80> ServerName server.example.com DocumentRoot /home/websites/mysource_matrix/core/web Options -Indexes FollowSymLinks <Directory /home/websites/mysource_matrix> Order deny,allow Deny from all </Directory> <DirectoryMatch "^/home/websites/mysource_matrix/(core/(web|lib)|data/public|fudge)"> Order allow,deny Allow from all </DirectoryMatch> <DirectoryMatch "^/home/websites/mysource_matrix/data/public/assets"> php_flag engine off </DirectoryMatch> <FilesMatch "\.inc$"> Order allow,deny Deny from all </FilesMatch> <LocationMatch "/(CVS|\.FFV)/"> Order allow,deny Deny from all </LocationMatch> Alias /__fudge /home/websites/mysource_matrix/fudge Alias /__data /home/websites/mysource_matrix/data/public Alias /__lib /home/websites/mysource_matrix/core/lib Alias / /home/websites/mysource_matrix/core/web/index.php/ </VirtualHost> My key requirements are: I don't want to worry/ know/ care about the server/ infrastructure Secure/ up to date software/ os Good monitoring Automatic scalability SLA I apologise for the length of the question. In short all I want to do is i). create vhost, ii). create db iii). install app/ site iv). relax. Thanks. Edit: I include the Matrix vhost because that is the only complication that I cannot really do via a .htaccess file.
