  • Upgrade Debian to unstable on VirtualBox: udev problem

    - by Ken
    I'm running Debian stable on VirtualBox on Windows Vista 64-bit Ultimate. It's been running great, but I needed some newer packages, so I put sid in my sources.list to upgrade to unstable (as I've done a dozen times on various Linux boxes over the years). When I upgraded, something went screwy and it asked me to run apt-get -f install to fix them, which gave this: (Reading database ... 77846 files and directories currently installed.) Preparing to replace udev 0.125-7+lenny3 (using .../archives/udev_151-3_amd64.deb) ... Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED feature is disabled in the running kernel. Please upgrade your kernel before or while upgrading udev. AT YOUR OWN RISK, you can force the installation of this version of udev WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file. There is always a safer way to upgrade, do not try this unless you understand what you are doing! dpkg: error processing /var/cache/apt/archives/udev_151-3_amd64.deb (--unpack): subprocess new pre-installation script returned error exit status 1 insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). Errors were encountered while processing: /var/cache/apt/archives/udev_151-3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I have the VirtualBox extensions installed, and it looks like the udev install doesn't know what to make of them. But I don't know exactly where/how they're installed (I just ran the VBoxLinuxAdditions-amd64.run script, basically), so I don't know how to disable them. Any ideas? Thanks!

  • Very slow write performance on Debian 6.0 (AMD64) with DMCRYPT/LVM/RAID1

    - by jdelic
    I'm seeing very strange performance characteristics on one of my servers. This server is running a simple two-disk software-RAID1 setup with LVM spanning /dev/md0. One of the logical volumes /dev/vg0/secure is encrypted using dmcrypt with LUKS and mounted with the sync and noatimes flag. Writing to that volume is incredibly slow at 1.8 MB/s and the CPU usage stays near 0%. There are 8 crpyto/1-8 processes running (it's a Intel Quadcore CPU). I hope that someone on serverfault has seen this before :-(. uname -a 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux Interestingly, when I read from the device I get good performance numbers: reading without encryption: $ dd if=/dev/vg0/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 68.8951 s, 95.1 MB/s reading with encryption: $ dd if=/dev/mapper/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 69.7116 s, 94.0 MB/s However, when I try to write to the device: $ dd if=/dev/zero of=./test bs=64k 8809+0 records in 8809+0 records out 577306624 bytes (577 MB) copied, 321.861 s, 1.8 MB/s Also, when I read I see CPU usage, when I write, the CPU stays at almost 0% usage.

  • Google Desktop Search problems - unable to disable indexing and no index status page

    - by Howiecamp
    I've been running Google Desktop (I've used both the regular and Enterprise versions) without issues on my Windows 7 64-bit PC for a long time with no issues. I just paved my PC and reinstalled Google Desktop (regular edition). Initially, I want to use it only for the CTRL-CTRL launcher capability - I don't want it to do any indexing. So I unchecked all the items in the configuration dialog as well as excluded c:. Despite this, it is indexing all the content on my hard drive as well as Outlook email, etc. In my previous installations I had the same options set and they worked properly. The other problem I have is that when you right-click on the Google Desktop system tray icon, there used to be an option for "Index Status" which showed you the percentage complete the index creation process was, as well as an option to clear and rebuild the index. Those are no longer there. I uninstalled the regular edition and installed the Enterprise Edition, but same problems. Any ideas?

  • Updating Dell PowerEdge firmware on Ubuntu?

    - by Shtééf
    The company I work for recently got hands on a batch of second hand PowerEdge SC1425 machines. We'd like to put these to good use. Our operating system of choice is Ubuntu Server 10.04 64-bit, which installs just peachy on this type of machine. Now I'd like to install the firmware updates from Dell, which are apparently marked as recommended. This includes the updates for the BIOS, the BMC, and possibly some other hardware. I find it incredibly difficult to locate the files on the Dell website, and install any of them on an Ubuntu system: I downloaded the file OM_6.2.0_SUU_A01.iso. I believe I've read that the SUU DVD should be able to update any recent PowerEdge. Is this correct? Is this the latest version? Besides the version number, does A01 have any meaning? Is this image bootable? (At the moment, I just nosed around with a loop device mount.) Running /bin/bash ./suu from the DVD, I get: # /bin/bash ./suu ./suu: line 262: ./java/linux/i386/bin/java: No such file or directory The file exists and is executable, though. But I cannot execute it directly from the shell either.

  • How do I only dp or do just the lines, not the entire block in Vim diff?

    - by hobbes3
    I'm currently using MacVim (Snapshot 64) "Split Diff by..." menu option. The file is Django's my settings.py from version 1.3.1 to a fresh file from version 1.4. (Open the image on a separate window/tab to enlarge.) I know two basic commands do to "obtain" (and replace) a block from the other side. dp to "put" (and replace) a block to the other side. But those two commands writes the entire block, which in MacVim is the purple highlights. If you look at the 2nd block, you can see that from line 2 and 3 only has 2 words that are different: mysite and hobbes3. I just want to replace per line not the entire block. So what is there a command to replace do do and dp per line as oppose to an entire block or do I have to manually type it out? Bonus question: I noticed that once I manually edit a block, I lose the purple highlighting. How do I "refresh" the diff again to include the highlights without reopening the file? Please try to keep the answers Vim-general as oppose to MacVim-specific. Thanks!

  • Can't get simple Apache VHost up and running

    - by TK Kocheran
    Unfortunately, I can't seem to get a simple Apache VHost online. I used to simply have one VHost which bound to all: <VirtualHost *:80>, but this isn't appropriate for security anymore. I need to have one VHost for localhost requests (ie my dev server) and one for incoming requests via my domain name. Here's my new VHost: NameVirtualHost domain1.com <VirtualHost domain1.com:80> DocumentRoot /var/www ServerName domain1.com </VirtualHost> <VirtualHost domain2.com:80> DocumentRoot /var/www ServerName domain2.com </VirtualHost> After I restart my server, I see the following errors in my log: [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs What am I doing wrong? EDIT As per the answer give below, I have modified my configuration.

They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # The configuration directives are grouped into three basic sections: # 1. Directives that control the operation of the Apache server process as a # whole (the 'global environment'). # 2. Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log" # with ServerRoot set to "" will be interpreted by the # server as "//var/log/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!

  • Multiple IPs on firewall, are these virtual interfaces or what?

    - by Jakobud
    We have 5 static IP addresses from our ISP: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 On our firewall box, the NIC that is connected to our cable modem, appears to have all 5 IP addresses set on it. A previous IT guy set this thing up, and I'm not sure exactly what he did. Are these virtual interfaces on this NIC or what? Here is my ip addr output for that NIC: rwd0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff inet XXX.XXX.XXX.180/24 brd XXX.XXX.XXX.186 scope global rwd0 inet XXX.XXX.XXX.181/29 brd XXX.XXX.XXX.186 scope global rwd0:FWB9 inet XXX.XXX.XXX.182/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB10 inet XXX.XXX.XXX.183/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB11 inet XXX.XXX.XXX.184/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB12 inet6 fe80::250:8bff:fe61:5734/64 scope link valid_lft forever preferred_lft forever I'm a bit new to firewalls and networking so I'm just trying to figure out what he had going on here. I know he used Firewall Builder to configure the iptables rules, maybe that has something to do with the "FWB" I see in those names? So my questions are: What is going on here? Virtual Interfaces? Or something else? If we want to put in a second firewall in parallel with this firewall but we only want it to handle traffic to XXX.XXX.XXX.182, how do we get rid of the static XXX.XXX.XXX.182 address on this existing firewall box?

  • Ubuntu xrandr rotate issue

    - by user83544
    I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

  • Connection reset by peer: mod_fcgid: error reading data from FastCGI server Issues

    - by user145857
    Help is greatly needed for our server. We are experiencing random "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" errors which cause a 500 internal server error. If the page is then reloaded it loads normally as it should. We are running MPM Worker with mod FCGID to handle PHP. We had APC cache enabled but disabled it recently to see if it would fix the problem, but the random mod FCGID errors are still continuing. No other opcode cache is active now. Our settings are below: <IfModule worker.c> MinSpareThreads 25 MaxSpareThreads 150 ThreadsPerChild 25 ThreadLimit 100 ServerLimit 700 MaxClients 700 MaxRequestsPerChild 0 </IfModule> <IfModule mod_fcgid.c> FcgidMaxRequestLen 1073741824 FcgidMaxRequestsPerProcess 2000 FcgidMaxProcessesPerClass 100 FcgidMinProcessesPerClass 0 FcgidConnectTimeout 300 FcgidIOTimeout 900 FcgidFixPathinfo 1 FcgidIdleTimeout 300 FcgidIdleScanInterval 120 FcgidBusyTimeout 300 FcgidBusyScanInterval 120 FcgidErrorScanInterval 12 FcgidZombieScanInterval 12 FcgidProcessLifeTime 3600 </IfModule> The server is a 64 core 2.1 GHZ 94 GB RAM so it has some power. Some of the fcgid timeout settings are higher because we run large reports which take up to 15 minutes. Any help is greatly appreciated! Just to clarify, the random fcgid errors are occurring when a user clicks a page on our site and the 500 error page loads instantly. This is random and occurrs less than 1% of the time but it is still an issue.

Why it's happening, but still I can not resolve this issue. Any ideas on what is happening here?

  • Current wisdom on SQL Server and Hyperthreading?

    - by BradC
    Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

  • Hard drive not correctly recognized on a new Windows 7 installation, but works correctly on Windows XP

    - by david
    I'm having problems configuring a hard disk in a brand new, clean Windows 7 installation. System specs: Hard disk: WD VelociRaptor WD6000HLHX (600 GB, 10000 RPM) Motherboard: Gigabyte Z77X-UD3H BIOS SATA mode set to AHCI (not RAID), with disk connected to SATA0 (6 Gb/s port). Windows 7 Enterprise SP1 64-bit The disk is recognized by the BIOS and is correctly identified, with the name and size correctly reported. Windows recognizes the disk itself and reports the device is functioning correctly, but it doesn't appear in Explorer. Disk Management shows the drive, but incorrectly states that it is uninitialized and has no partitions. If I try to initialize the drive, I get an error saying that "the system cannot find the file specified" (what file?). Before connecting the drive to the new machine, I partitioned and formatted it under Windows XP SP2, creating 2 partitions (MBR, not GPT) and copying over a boatload of data. However, none of this data appears under Windows 7. If I put the disk back into the Windows XP machine, I can access the disk and all of its data. Is it possible to get Windows 7 to correctly recognize the disk without having to erase it and start over? If so, how do I do so? I checked this question, which seems to cover the same issue, but it didn't help.

  • /usr/bin/python (Python 2.4) was deleted on CentOS 5. I compiled from source but yum is still broken. How can I get everything back to the way it was?

    - by Maxwell
    I saw a lot of other questions like this but none of them answered the exact part I am having trouble with (actually installing the Python RPM). Someone on my system deleted /usr/bin/python and /usr/bin/python2.4 on my 64 bit CentOS 5.8 installation. I recompiled Python 2.4 from source, but now whenever I try to yum install anything I get the following error: [root@cerulean-OW1 ~]# yum install httpd There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4 (#1, Dec 16 2012, 09:16:56) [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq I checked http://wiki.linux.duke.edu/YumFaq and it said the following: If you are getting a message that yum itself is the missing module then you probably installed it incorreclty (or installed the source rpm using make/make install). If possible, find a prebuilt rpm that will work for your system like one from Fedora or CentOS. Or, you can download the srpm and do a rpmbuild --rebuild yum*.src.rpm I tried going to http://rpm.pbone.net/index.php3/stat/4/idpl/17838875/dir/centos_5/com/python-2.4.3-46.el5.x86_64.rpm.html to install Python, which resulted in the following error: [root@cerulean-OW1 ~]# rpm -Uvh python-2.4.3-46.el5.x86_64.rpm error: Failed dependencies: python-libs-x86_64 = 2.4.3-46.el5 is needed by python-2.4.3-46.el5.x86_64 So I tried installing python-libs-x86_64, which resulted in the following: [root@cerulean-OW1 ~]# rpm -Uvh python-libs-2.4.3-46.el5_8.2.x86_64.rpm warning: python-libs-2.4.3-46.el5_8.2.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 192a7d7d Preparing... ########################################### [100%] package python-libs-2.4.3-46.el5_8.2.x86_64 is already installed file /usr/lib64/libpython2.4.so.1.0 from install of python-libs-2.4.3-46.el5_8.2.x86_64 conflicts with file from package python-libs-2.4.3-46.el5_8.2.x86_64

  • SQL Server 2005 SP3 on Windows 7 - No Management Studio

    - by Mike Thomas
    I've been trying for a day and a half now to get SQL Server 2005, DEV edition, to work on Windows 7, 64 bit prof. I install from the disk, then run SP 3. I get a failure on the Client Components section of the Installation Progress along with this vague message - Product : Client Components Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\SQLTools9_Hotfix_KB955706_sqlrun_tools.msp.log Error Number : 1712 Error Description : MSP Error: 1712 One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible. I've uninstalled all Visual Studio and tried to make this as clean as possible, and have read a lot of the blog posts, but am really at my wits end about this. I am not a DBA, but I use SQL Server all the time when coding and testing apps. Does anyone have any ideas as to where I can get this sorted out? I've been ati this for a long time and have never encountered an installation as bad as this one. Thanks Mike Thomas

  • High latency issue for web service call from amazon aws ec2 to local server

    - by SibzTer
    We have a legacy web application that is running in our data center on premises located in Houston. We have a developed a new .net 4 based web application in order to provide new features to customers. The new web application is hosted in amazon aws ec2 environment (N. Virginia region us-east-1b zone). In order to get seamlessly integrate with the legacy application the new web application makes web service calls to retrieve data. We are seeing an unusually high latency time in the order of 5+ seconds for these web service calls. The exact same web service call returns in less than a second on our local PCs (which makes sense given physical proximity to the actual server). The weird part is that we have developers in California who also have the same milliseconds response time. We are testing the web service response using third party tools such as SoapUI, Google Chrome extensions such as Advanced REST Client, Postman REST Client, etc. As if this wasnt weird enough, we have noticed the same low latency from certain other ec2 instances while testing which are in the same region and availability zone as well. If we experienced the high latency consistently from all the ec2 instances I could understand. But there is something else going on. Comparing the various stats and results between the low latency and high latency ec2 servers do not show any significant differences: ping (constant 40ms), tracert, winmtr, etc. We have instances that are in the VPC as well. So I tried both the public and private IP address of the web service host server and that didnt make a difference either for the above results. We need to resolve this latency issue as this is causing the resulting web pages to load very slowly (almost 15+ seconds which is simply unacceptable). The ec2 instances have Windows Server Datacenter 64 bit. Let me know if there is any other infor I can provide to help diagnose this.

  • Route traffic from one VPN to a second VPN

    - by Dominic
    I have set up an OpenVPN server on my windows 7 64-bit PC. I also have a subscription to a VPN service. My aim is to be able to connect my android phone to the VPN server on my PC, and then route all traffic through the VPN service. I have a NetGear WPN824 router. I can get it working if I my phone is on my local network. Then I can connect my phone to the VPN server using the local IP address of my PC. In Network Connection in the control panel, I share the connection used by the VPN service with the connection used by the VPN server. Then when I browse the internet on my phone, all traffic goes through the VPN service. Very nice. But if my phone is outside my local network, so I have to connect my phone to the local VPN using my PC's external IP address, then this method doesn't work. If I connect my PC to the VPN service and then try to connect my phone to my own VPN, it just doesn't connect (the initial TLS handshake times out). If I connect my phone to the local VPN first, then this connection is lost as soon as I connect my PC to the VPN service. Does anybody know how I can get this working? Many thanks Dominic

  • Resolving a BSOD/CPU/GPU issue...

    - by Christian Sciberras
    Hello all, I'm getting a BSOD / system crash (sometimes the PC just quits without a BSOD). Hardware Specifications cpu: i7 920 2666MHz / 8 cores (not OCed afaik) mobo: Asus P6T SE ram: 2x Corsair CM3X2G1333C9 (64bit DDR3 667MHz) gfx: ATI Radeon HD 5970 1GB (XFX HD5970 BE) os: Windows 7 Ultimate 64 bit (legit) All bios, firmware and drivers are all up to date (as of today). Symptoms Sometimes the PC runs smoothly, sometimes I get this BSOD. The BSOD always happens when I'm doing something related to graphics, such as viewing a video or playing a game. I get to know about the imminent BSOD ~10 seconds earlier; the PC starts freezing occasionally but increasing in frequency and length of lag (I noticed processor usage in creased from Process Monitor). I've tweaked BIOS settings occasionally but afaik, it was in vain. A day or so ago, I reset it to factory settings. BSOD contents The computer has rebooted from a bugcheck. The bugcheck was: 0x00000101 (0x0000000000000019, 0x0000000000000000, 0xfffff88001f35180, 0x0000000000000004). 15-12-2010 A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Internal Timer Error Processor ID: 4 23-12-2010 A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Internal Timer Error Processor ID: 2 Important The interesting thing is that although the event log (and BSOD screen) blame a "secondary processor", Windows Action Center sometimes blamed the GFX driver (for the same error). Also It is interesting to note that after hibernating my PC, I always get the BSOD.

  • Windows XP laptop doesn't appear in WSUS All computers list

    - by George
    I have this one laptop that doesn't appear in WSUS all computers list. We have about 23-25 PCs/laptops/servers in the network, all, but one are listed in WSUS. This is what I have done so far: 1) Changing Updates on local PC: Go to your Windows XP client and start a new Microsoft Management Console (MMC). At Start, Run, type MMC. Use Ctrl+M to add a new snap-in. Click Add, and then add the Group Policy Object Editor for the Local Computer. Click Close, and then click OK. Expand the Local Computer Policy. Under Computer Configuration, go to Administrative Templates, Windows Components, Windows Update. In the right-hand pane, double-click Specify intranet Microsoft update service location. Configure the settings to reflect my WSUS server. Click OK and then close the MMC without saving it. executed wuauclt.exe /detectnow 2) Edited registry key to be pushed to the PCs using GPO [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate] "WUServer"=http://wsusserver "TargetGroupEnabled"=dword:00000001 "TargetGroup"="WINXP" "WUStatusServer"=http://wsuswerver 3) executed wuauclt /resetauthorization /detectnow 4)Synchronised and refreshed the group I am running out of ideas here. The client is running Windows XP pro, WSUS version is 3.0 and is running on Windows 2008 R2 64-bit. Please, help! Thanks! EDIT 13.IX.2012 @ 15.40 I should have also mentioned that we do have a Windows Update GPO for workstations group and that laptop is a part of that group.

  • Can't make Dovecot communicate with Postfix using SASL (warning: SASL: Connect to private/auth failed: No such file or directory)

    - by Fred Rocha
    Solved. I will leave this as a reference to other people, as I have seen this error reported often enough on line. I had to change the path smtpd_sasl_path = private/auth in my /etc/postfix/main.cf to relative, instead of absolute. This is because in Debian Postfix runs chrooted (and how does this affect the path structure?! Anyone?) -- I am trying to get Dovecot to communicate with Postfix for SMTP support via SASL. the master plan is to be able to host multiple e-mail accounts on my (Debian Lenny 64 bits) server, using virtual users. Whenever I test my current configuration, by running telnet server-IP smtp I get the following error on mail.log warning: SASL: Connect to /var/spool/postfix/private/auth failed: No such file or directory Now, Dovecot is supposed to create the auth socket file, yet it doesn't. I have given the right privileges to the directory private, and even tried creating a auth file manually. The output of postconf -a is cyrus dovecot Am I correct in assuming from this that the package was compiled with SASL support? My dovecot.conf also holds client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } I have tried every solution out there, and am pretty much desperate after a full day of struggling with the issue. Can anybody help me, pretty please?

  • Safe place to put an executable file on Windows 7 (and Windows XP)

    - by Ricket
    I'm working on a tweak to our logon script which will copy an executable file to the local hard drive and then, using the schtasks command, schedule a task to run that executable daily. It's a standalone executable file, and when run it creates a folder in the working directory (which would be the same directory as the executable in this case). In Windows XP, of course, it can be put anywhere - I'd probably just throw it in C:\SomeRandomFolder and let it be. But this logon script also runs on Windows 7 64-bit machines, and those are trickier with UAC and all that. The user is a local administrator but UAC is enabled, so I'm pretty sure that the executable would be blocked from copying to a location like C:\ or C:\Program Files (since those seem to be at least mildly protected by UAC). The scheduled task needs to run under the user's profile, so I can't just run it with SYSTEM and ignore the UAC boundaries; I need to find a path which the user can copy into. Where can I copy this standalone executable file, so that the copy operation succeeds without a UAC prompt on Windows 7, the path is either common to both WinXP and Win7 or uses environment variables, and the scheduled task running with user permissions is able to launch the executable?

  • Domain joined computer unable to access servers through VPN

    - by kscott
    Our servers are in a virtual off site hosting center, our office has a vpn connection to the data center, but for reasons I don't understand we also have to connect to the Citrix Access Gateway (CAG) client in order to access the servers. I am a programmer with rather limited ops knowledge including a weak grasp of networking and terminology. Bear with me. I was just given a new laptop, which is a 64 bit Windows 7 system unlike my previous 32 bit Windows XP desktop which was able to connect without issue. My laptop has been joined to the domain so that I login with my AD credentials, I am able to connect to the CAG and get authenticated, and after doing this I can ping our servers and they resolve to the correct internal IP addresses, but I am unable to use remote desktop to the servers, connect to SQL servers through my local SQL Management Studio, navigate to them through the file system, or view any of our internal intranet websites. All of which I was able to do previously. I have tried turning off my Windows firewall and the problem remains, the DNS servers are set to the correct IPs of our domain controllers, and the ops guys here are a little stumped. Does any one have any suggestions?

  • Eclipse: Slow startup time

    - by ct2k7
    Hello, I've got Eclipse 3.6.1 on my MacBook Air (2010), and I'm getting slowish startup times. Well, slow, compared to my Desktop, which is somewhat less powerful and a few years old). The startup generally takes 15 seconds, and of this, 4 is spent just on the Eclipse splash screen, before Eclipse loads anything. No projects are open at startup. Here's a copy of my eclipse.ini. -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.1.R36x_v20100810 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Xms256m -Xmx512m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Dosgi.requiredJavaVersion=1.6 -Xverify:none -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:+StringCache -XX:+UseFastAccessorMethods -XX:+UseLargePages -XX:LargePageSizeInBytes=4m -XX:AllocatePrefetchLines=1 -XX:AllocatePrefetchStyle=1 -Dide.gc=true The problem doesn't seem to be related to plugins - I've disabled the ones which I don't need, and regardless of this configuration or whether all of them are selected on startup, it only takes 1second to load the plugins. I'm running Eclipse 3.6.1 Cocoa x64 build (vanilla) with the Zend Studio plugin. The machine has 4GB RAM, an SSD with over 64% free space, 1.6GHz (4MB L2 Cache). OS is Mac OS X 10.6.6, latest Java available, 1.6. For comparison, my Desktop, an old P4 3GHZ (512K L2 Cache) with a 7200RPM drive, under 40% free space, Eclipse (same config) loads in under 7 seconds, consistently. Note, this one is a Windows machine, with latest Java installed.

  • How do I configure a new (non-OS) raid device under Windows 7?

    - by GregH
    I recently installed 3 new 1TB drives in my Windows 7 (64 bit) system. These are in addition to the 10k rpm disk that I already have running the Windows 7 OS. My intent is to create a RAID 5 volume with the 3 disks. I don't seem to have a problem configuring the bios and creating the resulting 1.9 TB RAID volume. I run in to the problem when I try booting in to Windows. I get a quick flash of a blue screen and then am prompted by windows to do a repair. It tries to repair and then reboots. This sequence lasts indefinitely. If I re-configure the bios back to non-RAID (ACHI) then windows boots fine. The strange thing is that the 1.9 TB volume I configured through the bios actually shows up in windows! Strange since the motherboard is not set up with RAID. I assume that I somehow have to install the RAID drivers from the mobo manufacturer. How do I do this? Is the reason I'm getting the blue screen a result of not having the RAID drivers installed? It's strange because I can find plenty of documentation on how to set up RAID and do a fresh install Windows on to the RAID device, but nothing on how to set up a RAID device on an already running system. Advice is appreciated.
