• Windows 2003 print services for unix causing CUPS "lpd_command returning 1"

  - by Stephen P. Schaefer

  We have several Windows 2003 servers with print services for Unix on them, and which allow Linux machines running CUPS to use printers defined to CUPS with the URI lpd://printer_server/printer_queue_name - they work. An attempt to provide different printers on a different Windows 2003 server with print services for Unix newly enabled causes CUPS to behave like this: a newly defined printer will be in state "Idle". An attempt to print causes CUPS to change the printer state to "Disabled". In /var/log/cups/error_log, the relevant messages appear to be D [01/Dec/2012:06:14:18 -0800] [Job 16] lpd_command 02 hp775cm_ps D [01/Dec/2012:06:14:18 -0800] [Job 16] Sending command string (16 bytes)... D [01/Dec/2012:06:14:18 -0800] [Job 16] Reading command status... D [01/Dec/2012:06:14:18 -0800] [Job 16] lpd_command returning 1 E [01/Dec/2012:06:14:18 -0800] PID 18786 stopped with status 1! Since my Linux boxes can print to other printers via other Windows 2003 print spoolers, I'm wondering what obscure Windows component could be causing this. I don't think it is Windows firewall, since nmap sees the lpd port (515) open on the server. telnet to the server at port 515 declares Connected to server.internal.example.com (10.22.33.44). Escape character is '^]' Connection closed by foreign host. Windows clients successfully print to the CIFS/SMB share of the hp755cm_ps printer. What other reasons are there for Windows to refuse an lpd request?

• Cisco adaptive security appliance is dropping packets where SYN flag is not set

  - by Brett Ryan

  We have an apache instance sitting inside our DMZ which is configured to proxy requests to an internal NATed tomcat instance inside our network. It works fine, but then all of a sudden requests from apache to the tomcat instance stop getting through with the following in the apache logs: [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header Investigating into the Cisco log viewer reveals the following: Error Message %ASA-6-106015: Deny TCP (no connection) from IP_address/port to IP_address/port flags tcp_flags on interface interface_name. Explanation The adaptive security appliance discarded a TCP packet that has no associated connection in the adaptive security appliance connection table. The adaptive security appliance looks for a SYN flag in the packet, which indicates a request to establish a new connection. If the SYN flag is not set, and there is not an existing connection, the adaptive security appliance discards the packet. Recommended Action None required unless the adaptive security appliance receives a large volume of these invalid TCP packets. If this is the case, trace the packets to the source and determine the reason these packets were sent. All are machines are virtualised using VMware, and by default machines have been using the Intel E1000 emulated NIC. Our network administrator has changed this to a VMXNET3 driver in an attempt to correct the problem, we just have to wait and see if the problem persists as it's an intermittent problem. Is there something else that could be causing this problem? This isn't the first service where we have had similar issues. Our apache host is running Ubuntu 11.10 with a kernel version of 3.0.0-17-server. We have also had this issue on RHEL5 (5.8) running kernel 2.6.18-308.16.1.el5, this machine also has the E1000 NIC. NOTE: I am not a network administrator and am a software architect and analyst programmer responsible for these systems.

• How to use Salt Stack with minions all behind NAT (not publicly accessible, default salt ports not open)?

  - by MountainX

  Can Salt Stack minions communicate with the salt master from behind NAT/Firewalls, etc., using standard ports that would be open be default in all consumer NAT routers (and without the minions having a public DNS record or static IP)? I'm working my way through my first salt tutorial, and this is where I'm stuck. I am able to configure iptables on the Ubuntu salt-master. But I have no control over the routers/NAT that the minions will sit behind. So far I tried these settings: /etc/salt/master: publish_port: 465 ret_port: 443 /etc/salt/minion: master_port: 465 That did not work. Background: I have a custom developed application presently running on about 40 Kubuntu laptops (& more planned). Every few months I have to update the application. (Often this just amounts to replacing a .jar file, which requires root permissions.) I also have to run Ubuntu updates and a few other minor things. I've been doing it manually, one by one, using Team Viewer to log into each client. I would like to dramatically improve this process. The two options I'm aware of are either: use reverse ssh tunnels and bash scripts. I tested this and it works. But I don't get any of the reporting, etc., I would get with Salt Stack. use Salt Stack (or similar) management tool. But I need a really simple tool. I can't invest any time in a big learning curve. I looked at Puppet and a bunch of related tools. The only one I found that looked simple enough for me (so far) was Salt Stack. But I'm stuck now because my minion can't reach the salt-master, as stated above. I appreciate suggestions.

• Problem running Apache-Tomcat on every web browser installed in Windows 7

  - by Kush

  Hello everyone, I'm working on a web application in JSP and my web container is Apache Tomcat 7.0.2 (Its portable cross-platform version). As I've made extensive use of HTML5-CSS3 and my target browser is Google Chrome, I'm able to run the the Apache server only in Opera web browser, neither of the remaining installed browser run it. Here's the steps I have followed to start the server in my Windows 7 machine. -Placing the 'apache-tomcat-7.0.2' directory on my root partition (i.e. C: Drive) -Execute 'startup.bat' from 'bin' directory in it. (startup.sh if on Linux/Unix). -Then, a Console window opens that shows log during the setup of server (separately from Command Prompt), and I need to keep that console running in order to keep the Apache server running, so I minimize it. -Then, I open 'http://localhost:8080/' in various web browsers, and I could see Apache Server Homepage with same address only in Opera Web Browser (11.01), neither of other browsers installed can open it (Chrome 9, Firefox 4 Beta 10 or IE8). -I also tried other port numbers, but none of them worked. What can I do to make Apache run in every browser installed in my computer? I have my computer dual boot with Windows 7 and Ubuntu 10.10, and in Ubuntu, every web browser installed can run Apache once I start it, but same is not working in Windows.

• Executing Oracle SQLPlus in a Powershell Invoke-Command statement against a remote machine

  - by Scott Muc

  We have a basic powershell script that attempts to execute SQLPlus.exe on a remote machine. The remote does not have Oracle Instant client installed, but we have bundled all the necesary dlls in a remote folder. For example we have sqlplus.exe and dependencies in the directory C:\temp\oracle. If I navigate to that path on the remote server and execute sqlplus.exe it runs just fine. I get the prompt for username. If I go: Invoke-Command -comp remote.machine.host -ScriptBlock { C:\temp\oracle\sqplus.exe } I get the following: Error 57 initializing SQL*Plus + CategoryInfo : NotSpecified: (Error 57 initializing SQL*Plus:String) [], RemoteException + FullyQualifiedErrorId : NativeCommandError Error loading message shared library Thinking that it's potentially a PATH issue I tried the following: Invoke-Command -comp remote.machine.host -ScriptBlock { $env:ORACLE_HOME= "C:\temp\oracle"; $env:PATH = "$env:ORACLE_HOME; C:\temp\oracle\sqlplus.exe } This had the same result. The error code is not very helpful and is extremely frustrating since it does work when I log on to the machine. What is powershell remoting doing that's making this not work?

• How do I host node.js apps with pm2 without running them as root?

  - by jishi

  I have setup pm2 to run a node.js application, and I can successfully start it and it will resurrect upon reboot. However, the pm2 daemon is ran as root, which makes me think that all my node-scripts also runs as root? Even though I added them as a regular user in the system. The log files and stuff is created in the users home dir, /~/.pm2/logs, but the logs are owned by root. when I invoke pm2 startup (which handles the installation of the init.d script etc), it creates /etc/init.d/pm2-init.sh which looks like this: #!/bin/bash # chkconfig: 2345 98 02 # # description: PM2 next gen process manager for Node.js # processname: pm2 # ### BEGIN INIT INFO # Provides: pm2 # Required-Start: # Required-Stop: # Should-Start: # Should-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: PM2 init script # Description: PM2 is the next gen process manager for Node.js ### END INIT INFO NAME=pm2 PM2=/usr/local/lib/node_modules/pm2/bin/pm2 NODE=/usr/local/bin/node export HOME="/root" start() { echo "Starting $NAME" $NODE $PM2 stopAll $NODE $PM2 resurrect } stop() { $NODE $PM2 dump $NODE $PM2 stopAll } restart() { echo "Restarting $NAME" stop start } status() { echo "Status for $NAME:" $NODE $PM2 list RETVAL=$? } case "$1" in start) start ;; stop) stop ;; status) status ;; restart) restart ;; *) echo "Usage: {start|stop|status|restart}" exit 1 ;; esac exit $RETVAL When I dump the processes (which is what it will use when resurrecting the processes), I see mentions of user "USER":"pi" but I don't think that it's actually run as user pi. Any thoughts?

• Server 2008 R2 - Unable to install any printer drivers

  - by toffitomek

  My problem is exactly this same as described here: Server 2008 R2 - Unable to install any printer drivers Options - google groups I have few Windows 2008 R2 (no SP1) servers in remote offices, mostly in Domain Controller, and many of them have problems installing ANY printer drivers. following errors show up in Event Log when adding printer driver under Print and Document Services/Print Management/Print Services/ /Drivers OR trying any other way to install drivers: EventID 215: Installing printer driver - failed, error code 0x57, HRESULT 0x80070057. See the event user data for context information. EventID 215: Installing printer driver Canon iR C2380/2550 PCL6 failed, error code 0x0, HRESULT 0x80070057. See the event user data for context information. EventID 215: Installing printer driver Canon iR C2380/2550 PCL6 failed, error code 0x490, HRESULT 0x80070057.

Any help will be appreciated.

• Authenticating Windows 7 against MIT Kerberos 5

  - by tommed

  Hi There, I've been wracking my brains trying to get Windows 7 authenticating against a MIT Kerberos 5 Realm (which is running on an Arch Linux server). I've done the following on the server (aka dc1): Installed and configured a NTP time server Installed and configured DHCP and DNS (setup for the domain tnet.loc) Installed Kerberos from source Setup the database Configured the keytab Setup the ACL file with: *@TNET.LOC * Added a policy for my user and my machine: addpol users addpol admin addpol hosts ank -policy users [email protected] ank -policy admin tom/[email protected] ank -policy hosts host/wdesk3.tnet.loc -pw MYPASSWORDHERE I then did the following to the windows 7 client (aka wdesk3): Made sure the ip address was supplied by my DHCP server and dc1.tnet.loc pings ok Set the internet time server to my linux server (aka dc1.tnet.loc) Used ksetup to configure the realm: ksetup /SetRealm TNET.LOC ksetup /AddKdc dc1.tnet.loc ksetip /SetComputerPassword MYPASSWORDHERE ksetip /MapUser * * After some googl-ing I found that DES encryption was disabled by Windows 7 by default and I turned the policy on to support DES encryption over Kerberos Then I rebooted the windows client However after doing all that I still cannot login from my Windows client. :( Looking at the logs on the server; the request looks fine and everything works great, I think the issue is that the response from the KDC is not recognized by the Windows Client and a generic login error appears: "Login Failure: User name or password is invalid". The log file for the server looks like this (I tail'ed this so I know it's happening when the Windows machine attempts the login): Screen-shot: http://dl.dropbox.com/u/577250/email/login_attempt.png If I supply an invalid realm in the login window I get a completely different error message, so I don't think it's a connection problem from the client to the server? But I can't find any error logs on the Windows machine? (anyone know where these are?) If I try: runas /netonly /user:[email protected] cmd.exe everything works (although I don't get anything appear in the server logs, so I'm wondering if it's not touching the server for this??), but if I run: runas /user:[email protected] cmd.exe I get the same authentication error. Any Kerberos Gurus out there who can give me some ideas as to what to try next? pretty please?

• WS2008 subst in Logon script does not "stick"

  - by Frans

  I have a terminal server environment exclusively with Windows Server 2008. My problem is that I need to "map" a drive letter to each users Temp folder. This is due to a legacy app that requries a separate Temp folder for each user but which does not understand %temp%. So, just add "subst t: %temp%" to the logon script, right? The problem is that, even though the command runs, the subst doesn't "stick" and the user doesn't get a T: drive. Here is what I have tried; The simplest version: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "subst T: %temp%", 2, True That didn't work, so tried this for more debug information: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") Set procEnv = WinShell.Environment("Process") wscript.echo(procEnv("TEMP")) tempDir = procEnv("TEMP") WinShell.Run "subst T: " & tempDir, 3, True This shows me the correct temp path when the user logs in - but still no T: Drive. Decided to resort to brute force and put this in my login script: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "\\domain\sysvol\esl.hosted\scripts\tempdir.cmd", 3, True where \domain\sysvol\esl.hosted\scripts\tempdir.cmd has this content: echo on subst t: %temp% pause When I log in with the above then the command window opens up and I can see the subst command being executed correctly, with the correct path. But still no T: drive. I have tried running all of the above scripts outside of a login script and they always work perfectly - this problem only occurs when doing it from inside a login script. I found a passing reference on an MSFN forum about a similar problem when the user is already logged on to another machine - but I have this problem even without being logged on to another machine. Any suggestion on how to overcome this will be much appreciated.

• The System Event Notification Service service terminated with the following error: Overlapped I/O operation is in progress

  - by user38923

  When I start my Windows 7, I get a notification The system event notification service could not be started.... As a result, I dont have Aero, even though my Windows Experience Index is 3.2. Aero used to work fine before today and I have not installed any new application. I have checked the event log and it reads: The System Event Notification Service service terminated with the following error: Overlapped I/O operation is in progress. I am not sure what this means. I have seen the services.msc and everything is fine there. Moreover the startup time has also extended and the Please wait stays for more than a minute. This is a sudden problem as everything used to work fine until today. For Aero I have tried starting Desktop Window manager (as pointed out by the trouble shooter), but with avail. From what I could understand from the forums, the lack of Aero and increased start-up time comes from a single problem of the System Event Notification Service. This is a personal Computer and I have no active directories installed.

• Lync CMS replication is failing for all Domain Computers

  - by Ravi Kanneganti

  I have Lync Server 2010 and Active Directory installed on 2 different Windows Server 2008 R2 machines. I have added a Windows 7 PC to AD. And I have added this computer to Trusted Application Servers Pool and published the topology. I want to build an UCMA application to extend Lync Server functionality. I have installed UCMA 3.0 SDK in the same computer where Lync Server is residing. But, CMS Replication isn't happening and "Get-CsManagementStoreReplicationStatus" always gives Uptodate as "False" for my Windows 7 PC.

• Wacom consumer tablet driver service may crash while opening Bamboo Preferences, often after resuming computer from sleep

  - by DragonLord

  One of the ExpressKeys on my Wacom Bamboo Capture graphics tablet is mapped to Bamboo Preferences, so that I can quickly access the tablet settings and view the battery level (I have the Wireless Accessory Kit installed). However, when I connect the tablet to the computer, in wired or wireless mode, and attempt to open Bamboo Preferences, the Wacom consumer tablet driver service may crash, most often when I try to do so after resuming the computer from sleep. There is usually no direct indication of the crash (although I once did get Tablet Service for consumer driver stopped working and was closed), only that the cursor shows that the system is busy for a split second. When this happens, the pen no longer tracks on the screen when in proximity of the tablet (even though it is detected by the tablet itself); however, touch continues to function correctly. To recover from this condition, I need to restart the tablet driver services. I got tired of having to go through Task Manager to restart the service every time this happens, so I ended up writing the following command script, with a shortcut on the desktop for running it with elevated privileges: net stop TabletServicePen net start TabletServicePen net stop TouchServicePen net start TouchServicePen Is there something I can do to prevent these crashes from happening in the first place, or do I have have to deal with this issue until the driver is updated? Windows 7 Home Premium 64-bit. Tablet drivers are up to date. Technical details Action Center gives the following details about the crash in Reliability Monitor: Source Tablet Service for consumer driver Summary Stopped working Date ?10/?15/?2012 2:48 PM Status Report sent Description Faulting Application Path: C:\Program Files\Tablet\Pen\Pen_Tablet.exe Problem signature Problem Event Name: APPCRASH Application Name: Pen_Tablet.exe Application Version: 5.2.5.5 Application Timestamp: 4e694ecd Fault Module Name: Pen_Tablet.exe Fault Module Version: 5.2.5.5 Fault Module Timestamp: 4e694ecd Exception Code: c0000005 Exception Offset: 00000000002f6cde OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 9d4f Additional Information 2: 9d4f1c8d2c16a5d47e28521ff719cfba Additional Information 3: 375e Additional Information 4: 375ebb9963823eb7e450696f2abb66cc Extra information about the problem Bucket ID: 45598085 Exception code 0xC0000005 means STATUS_ACCESS_VIOLATION.

• Difficulty restoring a differential backup in SQL Server, 2 media families are expected or no files

  - by digiguru

  I have sql backups copied from server A to server B on a nightly basis. We want to move the sql server from server A to server B without much downtime, but the files are very large. I assumed that performing a differential backup and restore would solve the problem with the databases. Copy full backup from server A to copy to server B (10+gb) Open SQL Server Managment Studio on server B Right mouse on databases Restore Database Type in the new DB-name Choose "From Device" and browse to the backup file Click Okay. This is now resorting the original "full" backup. Test new db with dev application - everything works :) On original database rightmouse on DB Tasks Backup... Backup Type = Differential, Backup to disk, add a new file, and remove the old one (it needs to be a small file to transfer for the smallest amount of outage) Copy the diff backup onto the new db Right mouse on DB Tasks Restore Database This is where I get stuck. If I add both the new differential file, and the original backup to the restore process I get an error The media loaded on "M:\path\to\backup\full.bak" is formatted to support 1 media families, but 2 media families are expected according to the backup device specification. RESTORE HEADERONLY is terminating abnormally. But if I try to restore using just the differential file I get System.Data.SqlClient.SqlError: The log or differential backup cannot be restored because no files are ready to rollforward. (Microsoft.SqlServer.Smo) Any idea how to do it? Is there a better way of restoring backups with limited downtime?

• Remove Kernel Lock from Unmounted Mass Storage USB Device from the Command Line in Linux

  - by Casey

  I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output: $ dmesg | grep sd [20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0 [20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error: $ gphoto2 --list-config *** Error *** An error occurred in the io-library ('Could not lock the device'): Camera is already in use. *** Error (-60: 'Could not lock the device') *** What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed. The output of gphoto2 is then: # gphoto2 --list-config /Camera Configuration/Picture Settings/resolution /Camera Configuration/Picture Settings/shutter /Camera Configuration/Picture Settings/aperture /Camera Configuration/Picture Settings/color /Camera Configuration/Picture Settings/flash /Camera Configuration/Picture Settings/whitebalance /Camera Configuration/Picture Settings/focus-mode /Camera Configuration/Picture Settings/focus-pos /Camera Configuration/Picture Settings/exp /Camera Configuration/Picture Settings/exp-meter /Camera Configuration/Picture Settings/zoom /Camera Configuration/Picture Settings/dzoom /Camera Configuration/Picture Settings/iso /Camera Configuration/Camera Settings/date-time /Camera Configuration/Camera Settings/lcd-mode /Camera Configuration/Camera Settings/lcd-brightness /Camera Configuration/Camera Settings/lcd-auto-shutoff /Camera Configuration/Camera Settings/camera-power-save /Camera Configuration/Camera Settings/host-power-save /Camera Configuration/Camera Settings/timefmt Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.

• How can I trigger the creation of a new CLB file?

  - by Xperimental

  I'm currently having a problem with an application using COM running on Windows Vista. The application runs ok on one machine, but doesn't work on a similar configured machine. Both machines are virtual images originating from the same source image. While searching the registry for causes of this error, I came across the CLBVersion key in HKCR\CLSID which seems to have something to do with COM. The value of the key differs between the two machines (0x6 on the erroneous one, 0xc on the working one). Also there are files containing the same number in their filenames in the %SystemRoot\Registration directories of the machines. They are called R000000000006.clb and R00000000000c.clb respectively. I have already searched the windows event log for anything leading to the creation of those files (I have searched by the creation date of the files). Now a few questions regarding the registry keys and the files: Is it correct, that this is connected to COM? What is the function of the files? What causes the creation of a new "CLBVersion"? Is there a way for me to trigger the creation of a new CLB file? edit: I have now found out, that this has nothing to do with my application error. But I would still be interested in details about the registry key and the files. An installation of Visual Studio 2005 has brought the second machine to the same configuration (0xc in registry and file) as the other one.

• Apache Bad Request "Size of a request header field exceeds server limit" with Kerberos SSO

  - by Aurelin

  I'm setting up an SSO for Active Directory users through a website that runs on an Apache (Apache2 on SLES 11.1), and when testing with Firefox it all works fine. But when I try to open the website in Internet Explorer 8 (Windows 7), all I get is "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Authorization: Negotiate [ultra long string]" My vhost.cfg looks like this: <VirtualHost hostname:443> LimitRequestFieldSize 32760 LimitRequestLine 32760 LogLevel debug <Directory "/data/pwtool/sec-data/adbauth"> AuthName "Please login with your AD-credentials (Windows Account)" AuthType Kerberos KrbMethodNegotiate on KrbAuthRealms REALM.TLD KrbServiceName HTTP/hostname Krb5Keytab /data/pwtool/conf/http_hostname.krb5.keytab KrbMethodK5Passwd on KrbLocalUserMapping on Order allow,deny Allow from all </Directory> <Directory "/data/pwtool/sec-data/adbauth"> Require valid-user </Directory> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /etc/apache2/ssl.crt/hostname-server.crt SSLCertificateKeyFile /etc/apache2/ssl.key/hostname-server.key </VirtualHost> I also made sure that the cookies are deleted and tried several smaller values for LimitRequestFieldSize and LimitRequestLine. Another thing that seems weird to me is that even with LogLevel debug I won't get any logs about this. The log's last line is ssl_engine_kernel.c(1879): OpenSSL: Write: SSL negotiation finished successfully Does anyone have an idea about that?

• Dovecot install: what does this error mean?

  - by jamie

  I have postfix and dovecot installed on CentOS 6 (linode) along with MySQL. The table and user is already set up, postfix installed fine, but dovecot gives me this error in the mail log: Warning: Killed with signal 15 (by pid=9415 uid=0 code=kill) The next few lines say this: Apr 7 16:13:35 dovecot: master: Dovecot v2.0.9 starting up (core dumps disabled) Apr 7 16:13:35 dovecot: config: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:1: protocols=pop3s is no longer supported. to disable non-ssl pop3, use service pop3-login { inet_listener pop3 { p$ Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:5: ssl_cert_file has been replaced by ssl_cert = <file Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:6: ssl_key_file has been replaced by ssl_key = <file Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:8: namespace private {} has been replaced by namespace { type=private } Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:24: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely Apr 7 16:13:35 dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:25: auth_user has been replaced by service auth { user } I am following directions for the install on CentOS 5 with changes in the dovecot.conf file from different sources specific to CentOS 6. So the dovecot.conf file might not be correct, but there is no good source I have found yet for making dovecot install correctly. Can anyone tell me what the error above means? The terminal does not give any message as to start OK or FAIL. When I issue the service dovecot start command, it says: Starting Dovecot Imap: and nothing more.

• Windows 7 - Windows Update won't update

  - by StickFigs

  I'm trying to update my Windows 7 Professional 32-bit edition and when I try to tell Windows Update to scan for updates it failed with the error code 0x80096001. I checked out WindowsUpdate.log and it appears this is the problem: Validating signature for C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab: WARNING: Error: 0x80096001 when verifying trust for C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab WARNING: Digital Signatures on file C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab are not trusted: Error 0x80096001 How can I go about fixing this? It looks like it's just this one (corrupted?) file that's causing the problem. Thanks! UPDATE: Upon inspecting the file mentioned in the error message it appears that the file does not exist! What does this mean and how do I get it back? UPDATE 2: Ok it appears that the file in question appears only for a split second when Windows Updating is trying to search (but fails) to find updates. So I guess the problem doesn't have to do with the file specifically then.

• Query Execution Failed in Reporting Services reports

  - by Chris Herring

  I have some reporting services reports that talk to Analysis Services and at times they fail with the following error: An error occurred during client rendering. An error has occurred during report processing. Query execution failed for dataset 'AccountManagerAccountManager'. The connection cannot be used while an XmlReader object is open. This occurs sometimes when I change selections in the filter. It also occurs when the machine has been under heavy load and then will consistently error until SSAS is restarted.

• Problem posting multipart form data using Apache with mod_proxy to a mongrel instance

  - by Ryan E

  I am attempting to simulate my site's production environment as closely as I can on my local machine. This is a rails site that uses Apache w/ mod_proxy to forward requests to a mongrel cluster. On my Mac OSX Leopard machine, I have the default install of apache running and have configured a vhost to use mod_proxy to to forward requests to a local running mongrel instance on port 3000. <Proxy balancer://mongrel_cluster-development> BalancerMember http://127.0.0.1:3000 </Proxy> For the most part, this is working fine. I can browse my development site using the ServerName of the vhost I configured and can confirm that requests are being properly forwarded to the mongrel instance. However, there is a page on the site that has a multipart form that is used to upload an image to the server. When I post this form, there is a delay of about 5 minutes and the browser ultimately returns a Bad Request Your browser sent a request that this server could not understand. In the error log for my vhost: [Tue Sep 22 09:47:57 2009] [error] (70007)The timeout specified has expired: proxy: prefetch request body failed to 127.0.0.1:3000 (127.0.0.1) from ::1 () This same form works fine if I browse directly to the mongrel instance (http://127.0.0.1:3000). Anybody have any idea what the problem might be and how to fix it? If there is any important information that I neglected to include, post a comment, and I can add to this question. Note: Upon further investigation, this appears to be a problem specific to Safari. The form works fine in Firefox.

• Time machine disk icon on boot disk

  - by Ben Lings

  The icon for Macintosh HD (my boot disk) shows as a Time Machine disk. There is a file .com.apple.timemachine.supported in the root of the disk. If I delete the file and restart the computer, the icon goes back to a normal HD icon. However, the .com.apple.timemachine.supported file is recreated at some point on boot because when I log in again, the file has been recreated. If then reboot again, the icon goes back to being a Time Machine one. Any ideas about what is creating this file and why? More importantly - how can I get it to stop? It looks like something thinks the boot disk should be a Time Machine volume, but what? Console.app shows the following messages at approximately hourly intervals: 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Starting standard backup 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Cookie file is not readable or does not exist at path: /.<12 hex digits of MAC address for en0> 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Volume at path / does not appear to be the correct backup volume for this computer. (Cookies do not match) 19/01/2010 19:23:59 /System/Library/CoreServices/backupd[7459] Backup failed with error: 18 Other possibly relevant information: The boot HD isn't the original - the original failed so this is a SuperDuper'd clone of the original drive. I used to use the same disk for a SuperDuper clone as for Time Machine. These are the same same symptoms as this and this.
