• Issue with IIS...SERVER APPLICATION UNAVAILABLE

  - by SVI

  My web application was running absolutely fine. Just 2 days back, I got an error saying. SERVER APPLICATION UNAVAILABLE I am pretty certain that nothing was changed on IIS. Unless my automatic Windows updates screwed it up completely. My event viewer had zillions of following errors in Application category. aspnet_wp.exe could not be started. The error code for the failure is C0000005. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account. I reinstalled IIS. After installing, i ran aspnet_regiis -i for framework v2 and now it throws error saying - The application could not be initialized properly. Any ideas what going on?

• Regarding Reinstalling PostgreSQL

  - by Vivalavista

  I was using PostgreSQL 8.4. I tried removing it through Synaptic Manager and then I tried to install 9.1, but I still version 8.4. I deleted all the files associated with postgresql. Now I am unable to install any version of PostgreSQL. When I try I get this error: Setting up postgresql-9.1 (9.1.3-1~lucid) ... .: 12: Can't open /usr/share/postgresql-common/maintscripts-functions dpkg: error processing postgresql-9.1 (--configure): subprocess installed post-installation script returned error exit status 2 dpkg: dependency problems prevent configuration of postgresql: postgresql depends on postgresql-9.1; however: Package postgresql-9.1 is not configured yet. dpkg: error processing postgresql (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure.

• Ubuntu Server 12.04 LTS on Hyper-V 2012

  - by user137533

  I have the following scenario: Hyper-V 2012 server core installation. On top of this i created a virtual machine on which i tried installing Ubuntu Server 12.04 which should not have any compatibility issues according to what Microsoft and Ubuntu are saying (although it is not officially supported). I start, run the installation and everything is ok, no problems detecting the network device or the hard drive (unlike debian which didn't even detect the hard drive). Once the installation is complete it asks me to reboot, it unmounts the "dvd drive" and reboots. Once it tries to start again i get the following error: Boot failure. Reboot and Select proper Boot device or Insert Boot Media in the selected Boot device. It seems to not be booting up from the virtual hard drive. The hard drive is set up in SCSI mode, nothing mounted on the IDE controller (no iso image or anything else. Does anyone have any ideas on what i can do to solve this?

• Connecting to Exchange Server 2003 over POP using openssl s_client

  - by Andreas Jansson

  Hi, I'm trying to fetch emails programmatically from Exchange 2003 over POP. As a proof of concept I'm trying to connect using openssl s_client. I've started the POP service on my Exchange server. Trying to connect using openssl s_client -connect MYEXCHANGESERVER:995 returns 20303:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188: Trying openssl s_client -connect MYEXCHANGESERVER:995 -starttls pop3 returns CONNECTED(00000003) write:errno=32 Forgive a newb - I'm basically shooting wildly in the dark with no idea on what I'm supposed to be doing. In the past I've read my GMail over openssl s_client, and setting up those certificates was easy and well documented. I would imagine I need to set up some sort of certificate here as well, and I've looked a bit at using a .pfx file. But like I said, I'm completely lost here. Thankful for any advice, Andreas

• Computer can't boot

  - by zETO

  I have a 1 year old PC and the last weeks, when I press the ON button the PC doesn't power on ( Like I didn't press the ON button ). I have to plug and unplug a few times the power cord in order to make it work. At the start this happened once in 10 boots. Now it happens much more frequently to the point that when I press the power on button it never even opens if I don't do the cord switch thingy. Very rarely also, the PC shut downs for no reason and no warning, even when idle. The important fact to note here is, the green light on the motherboard is always on, even when the PC doesn't power on. What should I do? Is it a Power Supply failure or a motherboard? My power supply is a high end corsair model, AX850 and my motherboard a high end ASUS.

• One domain hiding two servers

  - by George DSeas

  For our SaaS web-app we have two identical servers in two geographically separated data centers. FOO_1 is the production server and does real-time (MySQL master-slave) replication to its backup F00_2. We want our users to always go to THEFOO.COM which somehow points to the production server. So even if FOO_1 dies, we can just switch THEFOO.COM to redirect to FOO_2 so the failure is transparent. This switch can be manual or automatic but without failback (if FOO_1 somehow becomes available again). Is there a way to do this with DNS? I am getting stuck with ANAME and CNAMEs configuration. We don't use sub-domains, just straight domains. If not, what are other options? Does it make sense to just have a web server at LOVELY_FOO.COM and just redirect all traffic? I also looked at load balancers but didn't see a solution for across data centers/network providers.

• nikto probe warning messages

  - by julio

  Hi-- I have a pretty standard VPS running Ubuntu 8.1, Apache 2.2, PHP 5 etc. -- standard Lamp stack. I am using suhosin and have tried my best to plug the obvious stuff, since I'm the only user-- there's no SSH access except via pubkey on a non-standard port, there's no root access by SSH, no FTP server running, iptables is set to discard anything outside of basically port 80 or my SSH port (there's no mail server or anything else). However, I've still been compromised (not badly as far as I can tell) probably by a SQL injection. I've locked down the SQL user (there's only one outside of root, and he's got limited priv, no file etc.) So I ran nikto to see what I'm doing wrong, and there's a list of things I've never seen, and can't find using "find" or any other method I'm aware of.

• Sending email using SMTP (Gmail) from Hudson CI

  - by jensendarren

  How can I set up Hudson CI so that I can send out emails from the server following a build failure? At the moment all I get is the following error: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first One solution is to start Hudson as follows: java -Dmail.smtp.starttls.enable="true" -jar /usr/share/hudson/hudson.war However, I am already using the following to start Hudson: sudo /etc/init.d/hudson start I am thinking the solution is to somehow set the system property mail.smtp.starttls.enable in a property file somewhere, but I have no idea how to do that. What are my options? Thank you all in advance!

• HP Recovery Manager failed creating a backup disc

  - by Baehr

  I had to restore my computer (running Windows 7) back to its factory default, so I ran the HP recovery manager disc and chose to reformat my computer. Before doing this I was given an option to backup my current files to a DVD, and I did so; getting the confirmation of a successful DVD burn. Booting up my computer everything looks like it did when I first purchased it (like expected). But when I pop in the backup DVD and run the recovery EXE inside it, the application creates a directory inside C:\System Recovery Files which contains the empty directories: [(^_^)] and Program Data. So essentially what I'm getting out of this is a failure in creating a back-up. Which is not only confusing but incredibly frusterating. Is there any way that I can recover the files lost in the

• Linux networking crash: best steps to find out the cause?

  - by Aron Rotteveel

  One of our Linux (CentOS) servers was unreachable last night. The server was not reachable in any way except for the remote console. After logging in with the remote console, it turned out I could not ping any outside hosts either. A simple service network restart solved the issue, but I am still wondering what could have caused this. My log files seem to indicate no error at all (except for the various daemons that need a network connection and failed after the network failure). Are there any additional steps I can take to find out the cause of this problem? EDIT: this just happened again. The server was completely unresponsive until I issued a networking service restart. Any advise is welcome. Could this be caused by a faulty hardware component? As per Madhatters request, here are some excerpts from the log at the time (the network crashed at 20:13): /var/log/messages: Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=101 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=100 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=101 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:13:34 graviton junglediskserver: Connection to gateway failed: xGatewayTransport - Connection to gateway failed.

• How to trigger cross-platform jobs between Windows and Unix

  - by andyb

  I have an application which has components on Windows and Unix. I need to run overnight jobs which initiate tasks/jobs on both environment. These need to be sequenced so I cannot simple use Cron / Task Scheduler. For each job, there will be a controlling script either on Windows or Unix, but this script will need to initiate jobs on the other environment and detect when they are complete and a success/failure code. In the past I have achieved this using 'flag files' on a samba share. This worked but required 'polling' behaviour on the receiving end which I do not consider optimal. I would prefer not to have to embed user credentials in script if possible.

• Cyrus: How Do I Configure saslauthd For Authentication?

  - by Nick

  I'm trying to get Cyrus IMAP (v 2.2 on Ubuntu 9.04) setup and working, but I'm having a bit of trouble getting the login working correctly. I've created a mailbox for my test user "nrahl": cm user/nrahl and then created a password: $ saslpasswd2 nrahl I'm attempting to connect to the mailbox using Thunderbird. I'm using the machine's LAN IP address as the host, and "nrahl" as the username. It connects to the server and prompts me for the password.

• How do I solve MSSQL 2008 install error, "The MOF compiler could not connect with the WMI server"?

  - by nbolton

  Possibly related to: SQL Server 2008 Install fails error reading etwcls.mof After manually removing MSSQL 2008 from my system (uninstall failed to remove two instances), I receive the following error when trying to re-install: The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start. It seems that mofcomp is failing with one of the .mof files, but I'm not sure which, or why. Digging through the connect article gave some indications, but no solution. I've run winmgmt /salvagerepository, which returns "WMI repository is consistent". Currently, I'm unable to install MSSQL 2008. Please help!

• Security Essentials not installing and I suspect my machine is infected with malware

  My mouse seems to be automatically right-clicking every few seconds, and sometimes constantly. My cursor will abruptly become an hourglass for a moment every once in a while, as well. It happens in spurts, as in it hasn't happened for about 10 minutes, but the preceding 20 before that it was happening constantly. I suspect that my machine is infected with malware of some sort, so I've tried installing Microsoft Security Essentials, but it presents the following error upon installation failure: My questions are: How can I solve the MSE installation issue and run a scan? Are there any indications that malware isn't actually my issue? Is MSE my best way to go about solving my issue, assuming that malware actually is the problem? Many thanks!

This happens for many large torrents that are running for several days (trying to download.) I try to "resume" and "force rechceck" but it never works. Smaller torrents seem to work ok. What is causing these torrents to never complete? Is there a way to force Deluge to keep auto-resuming every few minutes after a failure instead of just giving up?

• Ubuntu server failing daily

  - by deanvz

  Symptoms: Server becomes unresponsive - Increase in load, all services stop Loss of connectivity - Ping/SSH Flush MySQL hosts after reboot - As MySQL refuses new connections Intermittent Apache crashes Generally happens early morning hours - 2 days of the week are however excluded Changes made: Updated the OS - to Ubuntu 10.04.4 LTS Not sure if the MySQL server was also updated in the process Current MySQL version - mysql Ver 14.14 Distrib 5.1.63, for debian-linux-gnu (x86_64) using readline 6.1 Updated Plesk from 10.4.4 Update #47 to 11.0.9 Update #23 Rebooted on almost daily basis All crons stopped for the times corresponding to the server crashes Created a MySQL log to monitor the lock times on queries Possible causes: Failing hardware Incorrect software configuration (MySQL, Apache etc) Responsibilities: Small webserver Runs our billing system - WHMCS Responsible for CRONs Bulk-email solution - No delivery times coincide with server crashes Proposed solutions: Move machine over to VM Format and restore the Plesk server backup and take it from there? Side notes: Seems to be a general Apache failure across all our linux servers - Intermittent problem Are we doing something fundamentally wrong in the Apache config? (I understand that this is a secondary question, just making sure that it isnt possibly holding any relevance)

• Oracle Enterprise Manager Logs

  - by idea_

  Hi, I'm attempting to investigate the root cause of the following error which occurs each time a users call an Oracle 10g Forms applet: FRM-92102: A network error has occurred. The Forms Client has attempted to reestablish its connection to the Server 1 time(s) without success. Please check the network connection and try again later. Details... Java Exception: java.io.IOException: Connection failure with 503 This error remained after restarting all my system components: HTTP_Server, OC4J_BI_Forms, Web Cache, Reports Server, etc. The only way to clear this issue was to restart the server entirely. During the downtime, web pages were rendered with the PL/SQL cartridge and being served, so it appears as though this was isolated to forms. Does anybody know which log files may provide clues here? Any help would be much appreciated :) Update: If somebody can provide me with a way or reference to increase the capacity of my web server to minimize these errors, I will accept this as the solution.

• VPN Network intermittantly fails to provide internet: What could be possible causes

  - by Jake M

  We have a small office with our own VPN setup. We occasionally experience failures in our internet connection where we cannot access the internet. Most of the time the internet connection will resume by itself(without me doing anything) after a period of time(10 mins). Would you be able to suggest possible causes of the connection failure so I can then go and run some tests? Our network architecture is like so: A 'Billion' brand router that is connected to the internet via phone cable and then connected to our Cisco Switch A Cisco Switch/Bus which is connected to all our office nodes, our external harddrive and also to our router as stated above. All connections are via ethernet cable A series of work computers(nodes) connected via ethernet cable to the Cisco switch. Our ISP is TPG Australia We have a Virtual Private Network All the ethernet cables are about 3 years old Do you think that the causes of our intermittant connection problems could be due to the following: Data collisions in the ethernet cables Old/Faulty ethernet cables Our ISP has bad service Can you think of any other causes of the problem?

• sqlcmd backup script failing

  - by Bryan

  I'm trying to use a simple batch script to backup a local instance of SQL Express 2012, as follows: @echo off SET BACKUP_DIR=E:\BackupData SET SERVER=.\\sqlexpress set dom=%date:~0,2% set month=%date:~3,2% set year=%date:~6,4% set file=%year%-%month%-%dom% sqlcmd -S %SERVER% -d master -Q "exec sp_msforeachdb 'BACKUP DATABASE [?] TO DISK=''%BACKUP_DIR%\?.Full.%file%.bak''' The script is failing to run with the following error: Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Client unable to establish connection due to prelogin failure. This is on Server 2008 R2, my SQL database (on localhost) instance is named SQLEXPRESS. There is an instance of SQL Express 2008 on the system (hence client 10.0). The database is configured to use a trusted connection, and the .net desktop software deployed on our network PCs is able to access the database without any problem. Am I missing something obvious here, I've done a fair amount of searching for this error message, and haven't found anything that has been particularly useful so far.
