• "Server Unavailable" and removed permissions on .NET sites after Windows Update [closed]

  - by andrewcameron

  Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.

• Application for time and projet management

  - by user10826

  I want to improve the way I organize my projects/tasks/schedule What I do now is: keep an excel sheet with the name of the most important tasks/projects, I look at it at the beginning of each day and decide the ones I will focus on on iCal I write down events for each day, or for a concrete time (13 to 14 hours). I set up each day the tasks I want to accomlish, and allocate them hours I use Things (culture code) to keep info about tasks and projects not very important and which are not time allocated yet (GTD name = someday) I use Mail on Mac and create folders for the mails I want to process with the name of the different projects I save the main info for each project on freemind maps My system works well at the moment but it is pretty complicated to use. I want to make it better and I am looking for something with these requirements: must be 100% offline accessable it should use as less programs/resources as possible, ideally just one program should be able to manage all my info I can use the GTD methodology mixed with priorities and I can allocate each task converted to event on my calendar I can have different daily/weekly, etc views on a calendar to see the "big picture" must run on mac os x leopard price does not matter, I will pay for this So, according to your experience, can you recommend me something like this? Thanks

• Windows 2008 64bit: applications and explorer always hang

  - by Phil Farthing

  I setup a couple of Window 2008 64bit systems about 5 months ago. Initially all seemed well. Now however, for no apparent reason, things are dog slow, apps hang, explorer hangs, just clicking on something can cause a CPU spike of 100%, and often it's explorer that is eating it up. As I have two on identical hardware, and they experience the same problem, it doesn't seem related to addon software. The only thing these have in common is Kaspersky and I've tried disabling/uninstalling to no avail. There are no useful error messages in the event logs. Actually, the system never even reports app hangs. Sometimes, it similar to what I've seen on Windows 7 systems where the screen goes milky and asks if I want to trouble shoot, that's only when get impatient and click happy. The really odd thing, is that it will NOT do this for a few minutes at a time, and then starts up again. Like I will click on the start menu and browse for the Admin Tools, the start menu will hang at some point and I'll have to wait about a minute, then it's OK. The next time I do this, a few seconds later, it's fine. Every click seems to hang the first time around, then be ok the second time if I do the exact same thing. If anyone has any suggestions, please PLEASE let me know! thanks =)

• Exchange 2010 Hub cannot deliver to Exchange 2007 Hub - "451 5.7.3 Cannot achieve Exchange Server authentication"

  - by Graeme Donaldson

  We have an existing Exchange 2007 server in Site A (exch07). I've installed an Exchange 2010 server in Site B (exch10). Both servers have the CAS, Mailbox and Hub roles. Messages sent via SMTP on exch10 which are destined for mailboxes on exch07 are queued with the "Last Error" reported in Queue Viewer as '451 4.4.0 Primary target IP address responded with: "451 5.7.3 Cannot achieve Exchange Server authentication." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts.' I've found that some people have resolved this by creating new Receive Connectors which are scoped specifically to apply to connections from the remote hub/s, but I have had no luck doing this. Specifically I created new receive connectors on both servers with the following settings: Remote IP = IP/s of remote server Authentication = "Transport Layer Security (TLS)" and "Exchange Server authentication" Permission Groups = "Exchange servers" and "Legacy Exchange Servers" This made no difference, I see the same error message. What am I missing? Update: We noticed that the Application log had this error message from MSExchangeTransportService: Microsoft Exchange could not find a certificate that contains the domain name exch07.domain.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector exch10 with a FQDN parameter of exch07.domain.local. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. It turns out that the default self-signed certificate was no longer enabled for the SMTP service for some reason. After enabling the self-signed certificate for SMTP, we no longer get the error in the event logs, but delivery is still failing with the same error message. Update 2: I put a mailbox on exch10 and attempted to deliver a message via SMTP on exch07 and I get the same error.

• How to diagnose website performance/app pool recycling with Windows 2008/IIS7

  - by ilasno

  Ok, so there are various symptoms here (clients and and our own employees complaining of intermittent slowdowns, getting 'kicked out' to login page or just having a save request not properly save the submitted data). The environment: Windows Server 2008 (Datacenter), Service Pack 2, 64-bit, 2x2.8 GHz processors, 7.5 GB RAM MS SQL Server 2008 (running on the same machine) IIS 7 There are ~10 websites running on the server, each in their own application pool - most of these pools are running in Integrated mode, 2 are in Classic, all are on .NET 2.0 and all run as ApplicationPoolIdentity. I'm trying to analyze, diagnose, and troubleshoot and am struggling with where to get more info about what could be happening. Here are some steps i have already taken: Set each application pool to recycle once per day, and removed any other automatic recycling Set a Virtual Memory Limit for each to 1024000KB (1GB) Enabled ALL 'Generate Recycle Event Log Entry' entries (Config Changes, Isapi Reported Unhealthy, Manual Recycle, Private Memory Limit Exceeded, Regular Time Interval, Request Limit Exceeded, Specific Time, Virtual Memory Limit Exceeded) I have seen the app pool processes recycle (in Task Manager) - a new one will start up, and then the first one dies off - and this has happened without the memory or time going over the settings. This is a fairly new server, and most of these came from Windows Server 2003/IIS6. Any 'next steps' for setting up information gathering, logging, diagnosing, etc. would be much appreciated! j

• filesystem compatible with freenas and windows

  - by Daniel

  Hi all, I'm planning on using FreeNAS (was considering openfiler but freenas seems simpler) for my home NAS box running off ESXI. I have managed to get local sata drives to mount in ESXI (http://serverfault.com/questions/216902/esxi-add-datastore-without-partitioning). I've had one of the drives fail on my before and I was able to retrieve most of the data off it using windows tools (I'm not much of a linux guy I know enough to be dangerous!). If I go the freenas route in the event that something goes bad what would be the best file system to use so that I could pop the drive out of the freenas box (vm) and put it in another pc running windows so I could try and run various recovery tools to get the data back. All in all its not a major problem if I lose the data just would be a bit annoying, so I'm not looking for suggestions around backing up etc. I was considering using NTFS that the drives are already formatted as but it appears that while freenas does support NTFS that its a bit buggy and not 100% reliable, anyone know if this is still true? Read that on a forum somewhere.

• SkyDrive broken after upgrade to Windows 8.1: "This location can't be found, please try later"

  - by avo

  Upgrading from Windows 8 to Windows 8.1 via the Store upgrade path has screwed my SkyDrive. The C:\Users\<user name>\SkyDrive folder is empty (it only has single file desktop.ini). When I open the native (Store) SkyDrive app, I see "This location can't be found, please try later". I'm glad to still have my files alive online in my SkyDrive account. I tried disconneting from / reconnecting to my Microsoft Account with no luck. Anyone has an idea on how to fix this without reinstalling/refreshing Windows 8.1? From Event Viewer: Faulting application name: skydrive.exe, version: 6.3.9600.16412, time stamp: 0x5243d370 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0x00000000 Fault offset: 0x0000000000000000 Faulting process ID: 0x4e8 Faulting application start time: 0x01cece256589c7ee Faulting application path: C:\Windows\System32\skydrive.exe Faulting module path: unknown Report ID: {...} Faulting package full name: Faulting package-relative application ID: Also: The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {C2F03A33-21F5-47FA-B4BB-156362A2F239} and APPID {316CDED5-E4AE-4B15-9113-7055D84DCC97} to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool. Never was a big fan of in-place upgrade anyway, but this time it was a machine which I use for work, with a lot of stuff already installed on it. Shouldn't have tried to upgrade it in the first place, but was convinced Windows 8.1 is a solid update. Another lesson learnt.

• Mysql master-master not replicating

  - by frankil

  I'm setting up a master-master mysql replication on two servers (db1 and db2). I started with setting up db2 as a slave to db1 and that works fine. But when I set up db1 as a slave to db2 it isn't replicating. On the face of it everything looks fine but the data isn't replicating. There are no errors in either of the error logs. The slave status is updating the bin log position. I have used mysqlbinlog to examine both the binlog on the db2 and the relay log on db1 and all of the queries are going in there, but not being executed to db1. "show slave status" on both servers shows that both the slave io and sql threads are "Yes" and that the relay log position is updated by the sql thread. Also on both servers: >echo "show processlist" | mysql | grep "system user" 166819 system user NULL Connect 3655 Waiting for master to send event NULL 166820 system user NULL Connect 3507 Has read all relay log; waiting for the slave I/O thread to update it NULL Relevant config for db1: server-id = 1 log-slave-updates replicate-same-server-id = 0 auto_increment_increment = 4 auto_increment_offset = 1 master-host = db2 master-port = 3306 master-user = slaveuser master-password = *** skip-slave-start sync_binlog = 1 binlog-ignore-db=mysql Config for db2 server-id = 2 log-slave-updates replicate-same-server-id = 0 auto_increment_increment = 4 auto_increment_offset = 2 master-host = db1 master-port = 3306 master-user = slaveuser master-password = *** sync_binlog = 1 relay-log=mysql-relay-bin binlog-ignore-db=mysql What else can I look for to make sure db1 executes the queries from db2?

• Windows Remote Desktop: "configuring remote session" closes without error

  - by icelava

  I have a desktop/laptop pair at home operating x64 Windows 7 (the desktop was upgraded from Windows Vista, works just fine). I remote desktop to them on a daily basis when outside. In recent weeks, I would occasionally fail to connect to my desktop. It can connect and authenticate fine, but the "configuring remote session" dialog would simply close and not show me the desktop window or any error message. There is no error event log relating to this on the desktop computer. Some suggestions call for disabling remote audio, which mine already is, but trying different audio modes did not yield any different result. I am not too sure if this is related to video card drivers (they do get auto-updated), since remote desktop video is supposed to steer via a virtual device driver? Nonetheless the desktop operates three monitors via an ATI Radeon HD5770 (1 Displayport, 2 DVI). I do not see a real problem with that since I can mostly connect and operate it remotely. I try to "remote tunnel" via my home laptop but obviously won't work either as the problem lies in the desktop. What other conditions can cause remote desktop to break without error? UPDATE I came home and still couldn't connect to the desktop until I restarted the entire system.

• Mail to Mailenable group sometimes bounces back because it cannot find one of the group members

  - by Stanley

  I am using MailEnable Enterprise Edition 6.53. On one of my PostOffices I have a group address set up with 5 members in the group. Under normal circumstances when someone sends a mail to this group then the mail gets successfully forwarded to all 5 members in the group. However, every now and then when a recipient sends to the group they get a bounce back message from us that the mail could not be delivered because one of the user's addresses was not found on the server. This could happen for any one of the 5 users in the group. The error message looks like: Message could not be delivered. Error was: The email address is not available on this system The following recipient(s) could not be reached: [SF:mydomain.com/my_username] What could be causing this and how do I fix it? Obviously the mailbox DOES exist as, under normal circumstances, when someone mails the group the mail gets delivered successfully and forwarded to all group members. All the mailboxes most definitely DO exist on the system. EDIT: I have done more investigation and I see an error in Windows Event Viewer: MailEnable Database Provider error: 0 FAILURE: (SQLDriverConnect), Module: MEIMAPS.exe; Error: [Microsoft][ODBC SQL Server Driver]Timeout expired This seems to be related to http://forum.mailenable.com/viewtopic.php?p=53157 and http://www.mailenable.com/kb/content/view.asp?ID=ME020535 but the setups in these links use MySQL as a database whereas we use SQL Server. Maybe this shines some new light on the problem?

• Did a recent WinXP update break CD/DVD read speeds? SP2/SP3

  - by quack quixote

  I have two systems with fresh installations of Windows XP Pro SP3 (SP3 slipstreamed into the installer; fully updated after install). One's a refurbished 2.4GHz Pentium4 system; the other is a new 1.6GHz Atom330 build. Both have brand-new dual-layer CD/DVD burners (one's a LiteOn IDE, the other an LG SATA). Both take a really looooong time to read a single-layer DVD in Windows with Cygwin tools. Specifically, 40 minutes or more. I burn backup data to single-layer DVD+/-R and use MD5 hashes for data verification (made with the standard md5sum tool in Unix or Cygwin). The hashes are burned to disc with the data files, and I use this command to verify: $ cd /path/to/disc/mountpoint ; time md5sum -c < md5.txt Here's how long that takes to run on a full single-layer DVD+/-R disc: Old system (WinXP SP2, 1.8GHz Athlon 2500+, last summer): ~10 minutes Old system (Ubuntu 9.04, 1.8GHz Athlon 2500+): ~10 minutes Old system (Debian 5, dual 550MHz P3): ~10 minutes New Pentium4 system (running Ubuntu 9.04): ~5 minutes New Pentium4 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes New Atom330 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes Now the weird stuff: Old system (WinXP SP2, 1.8GHz Athlon 2500+, today): ~25 minutes New Pentium4 system (running WinXP SP3, read from Cygwin): ~40-50 minutes (?!!) New Atom330 system (running WinXP SP3, read from Cygwin): ~40 minutes (can do it in ~30 minutes ...if i have another program spin up the drive first) Since both systems will copy files in 6 minutes using Windows Explorer, I know it's not a hardware problem. Windows just never spins up the drive during the Cygwin read, so it stays super-slow the whole time. Other programs like EAC and DVD Decrypter seem to spin up the disc just fine during their processing. DMA is enabled on both systems. (Can confirm in Windows' Device Manager on the Atom330, not on the P4.) Nero's DriveSpeed tool doesn't seem to have any effect. Copy times are comparable from commandline with Windows' xcopy. Copying with Cygwin's cp looks more like the problem state -- it will spin up the drive for a short time, never reaches full speed, and lets it spin back down again for most of the copy. What I need is to get full read speeds from Cygwin. Is this a known issue with SP3 or some other recent Windows update? Any other ideas? Update: More testing; Windows will spin up the drive when data is copied with Windows tools, but not when read in place or copied with Cygwin tools. It doesn't make sense to me that Windows spins up the drive for copying, but not for other reads. Might be more of a Cygwin problem? Update 2: GUI activity is sluggish during the problem state -- during the Cygwin verifies, there's a slight but noticable delay when dragging windows or icons around on the desktop, switching windows, Alt-Tabbing through open applications, opening new windows, etc. It reminds me of the delay when opening a Windows Explorer window on My Computer just after inserting a DVD. I've tried updating Cygwin (from 1.5.x to 1.7.x), but no change in the problem behavior. I've also noticed this issue occurs on WinXP SP2, but it's not exactly the same -- some spin-up occurs, so the read happens in ~25-30 minutes instead of 40+. The SP2 system used to run the verifies in ~10 minutes, and when it first changed (not sure exactly when, maybe in late November or early December 2009) I thought it was dying hardware. This is why I suspect an official update of breaking this functionality; this has worked for years on that SP2 box.

• Motion - can't get streaming working from a webcam

  - by Emmanuel Brunet

  I'm trying to record a video stream from my Tenvis IP camera with motion 3.2.12 on Debian 7.5.

• Websockets Server with Fault-Tolerance and Durable Message Store

  - by smitchell360

  I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for. EDIT So, after some research the following installed options seem to be the most robust: Kaazing Migratory Migratory (http://migratory.ro) Hosted services that seem "real" Pusher (great API but no history feature yet) PubNub (has history) All of the above services have graceful fallback to other communication methods if websockets are not available. I was not able to find any open source that provided "out of the box" clustering, fail-over, and a durable message store to play back history. There are some projects that may serve as good starting points, but not exactly what I am looking for.

• Active Directory Child Domain Replication Problems

  - by MikeR

  Hi, I've recently inherited an Active Directory (all DCs Windows 2003) which has been configured with several child domains that are used as test environments for out CRM software. Two of these child domains have been used for testing using dates in the future (2015), throwing them well outside of the Kerberos tolerance for time, and they're flooding my event logs with replication errors such as the following: Description: The attempt to establish a replication link for the following writable directory partition failed. Directory partition: CN=Schema,CN=Configuration,DC=ad,DC=xxxxxxx,DC=com Source domain controller: CN=NTDS Settings,CN=TESTDC001,CN=Servers,CN=SiteName,CN=Sites,CN=Configuration,DC=ad,DC=xxxxxxx,DC=com Source domain controller address: 38e95b2a-35af-4174-84ba-9ab039528cce._msdcs.ad.xxxxxxx.com Intersite transport (if any): This domain controller will be unable to replicate with the source domain controller until this problem is corrected. User Action Verify if the source domain controller is accessible or network connectivity is available. Additional Data Error value: 5 Access is denied. I'd also like to upgrade to Windows 2008 at some point, but wouldn't want to attempt any schema updates while I'm not 100% confident on the replication. I'm guessing my only real solution will be to get rid of these child domains. The child domains are operating as stand alone domains, the DC is up and running and authenticating test users fine. I'm guessing the best solution to this would be to delete the domains (although I'd be happily told otherwise). The clock forwarding appears to have been happening for several years, so I'm assuming I can't just put the clock right (I'm guessing scope for this would be 180days, the same as the tombstone lifetime) With the replication errors would I be able to dcpromo the child domains DC, select it as the last domain controller in the domain and the child domain would be deleted? Or would I be better off treating the domain as an orphaned domain and use Microsoft's instructions to clear up as such. Any advice would be much appreciated.

• Exchange MSExchangeIS Mailbox Store Error

  - by Bart Silverstrim

  Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.

• Converting An Older VMWare Image to ESXi

  - by Bart Silverstrim

  I have just installed VMWare ESXi and imported one physical machine without issue and one virtual machine, from an older version of VMWare Server on a Linux system, to it without issue. But I have another machine (Windows XP), virtual running on the VMWare Server, that I can't get the Converter to work with. Converter runs, says everything is fine, but when I go to the ESXi VSphere manager and hit the button to power up that vm, the console stays black with a blinking cursor and the processor for that VM spikes 100% and stays there. An event log item in VSphere warns something about activation issues with Windows. Has anyone else run into this issue before? Is it something with the disk controller? I copied the folder with the VM directly to the storage drive on ESXi hoping to create a new machine and point the data store to that folder or at least that drive image; nope, something about not using an IDE controller (must be something with the older format). In short, converter is doing something that particular machine doesn't like, and I can't find a way to simply open that hard disk image or convert it unless someone else has seen this. I try attaching a bootable CD image for disk repair to see if it can check the hard drive but I can't seem to get the console to boot from it...either too slow on the button or it just isn't able to easily boot from a virtual drive image (.iso). Any suggestions or help?

• CHKDSK is unable to fix NTFS errors

  - by HackToHell

  After my PC shutdown due to power failure, I noticed several errors in EventViewer. The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolume2. and The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume C:. So I forced a chkdsk check at startup, and it finds a stream of error, here is the output, it is smaller than the actual log, because, Event Viewer only seems to have this much, the same line was repeated thousands of times.Here is that line. Some clusters occupied by attribute of type 0x80 and instance tag 0x4 in file 0x198f2 is already in use. Deleting corrupt attribute record (128, "") from file record segment 104690. Attribute record of type 0x80 and instance tag 0x0 is cross linked Also, even after running CHKDSK, the same errors were being reported again so I ran CHKDSK another time and it still loops the same line above, without fixing the error. Can anyone tell me how to fix it?

• How to diagnose occasional sudden resets?

  - by steve314

  I have a Windows XP system, and have recently upgraded by adding 2 1GB sticks of RAM to the 2x0.5GB already present. Since then, about once per day (the system is used 8+ hours per day), the system has suddenly and unexpectedly reset. On a couple of occasions, the system has frozen completely, only responding to the power button being held in for several seconds to force power off. Nothing at all ever appears in the system event log that might indicate a possible cause - everything seems to suggest business as usual. Sounds like faulty memory - but memtest86+ says otherwise. A full test, taking over an hour, found no issues. The next likely suspicion, then, is that I've knocked something while installing the RAM. Trouble is, everything I can think of to test seems fine. I've opened up the case and prodded a few things around, hoping to get better contact on connections etc, but there's no sign yet as to whether that has made a difference or not. I thought about a malware-related timing fluke, but again, so far as I can tell I'm all clear. All I can think of to add to my checklist (mainly of things that I can't easily check) is... The power supply is (1) only 350W, (2) not necessarily the best quality, and (3) powering a Prescott P4 640 3.2GHz. Could that be borderline overloaded or about to die? How do I check? Is it possible that the CPU isn't getting cooled properly? I haven't had the fan past normal tickover even doing video encoding, and the only sane temperature reading from SpeedFan is pretty steady at 36 celcius, so probably not. Any thoughts? Is there a standard procedure for diagnosing this kind of fault?

• Libvirt / QEmu Machine Fails and Refuses Restart Because of Memory Allocation Errors

  - by Elmar Weber

  I'm having a problem with libvirt. On a system restart all virtual machines (VMs) are started without a problem and keep running. Then at some point in time a set of machines shuts down according to their log. When I try to restart the machine, I'm getting an error that the memory allocation failed, although more than enough memory is free. server ~ # free total used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buffers/cache: 14789744 1386904 Swap: 0 0 0 server ~ # virsh start zimbra error: Failed to start domain zimbra error: Unable to read from monitor: Connection reset by peer server ~ # tail -n 4 /var/log/libvirt/qemu/zimbra.log LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 3072 -smp 2,sockets=2,cores=1,threads=1 -name zimbra -uuid d05ddb7a-83c4-a77b-d8bc-a322648520cf -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/zimbra.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -drive file=/var/lib/libvirt/images/zimbra.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=19,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:21:a9:ad,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 192.168.1.2:25 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/2 Failed to allocate 3221225472 B: Cannot allocate memory 2012-07-06 08:42:56.076+0000: shutting down server ~ # uname -a Linux server 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The system is a Ubuntu 12.04 server.

Any suggestions on how to debug this? Best regards, elm

• Suspected brute force attack

  - by HarveySaayman

  Recently I acquired a dedicated server from a local ISP to play around with. As the tags suggest, its a windows server 2008 R2 machine. I've only had it for a few days, and no real traffic is going to it yet. I haven't even deployed a "real" website to it yet. Just a silly page so that I could check IIS, my host headers, DNS records, etc are all configured correctly. While playing around, I noticed a ton of Audit Failure entries in the event viewers security logs. It seems something is trying to access the administrator account, and failing. It smells like a brute force attack to me. My ISP gave me the account details of the administrator account and I used those to RDP into the box, which I've heard is not the securest of situations. I created myself another account and added myself to the administrator group, so im using that account to gain acceess to the machine now. In response to all of this i used http://strongpasswordgenerator.com/ to generate me some 20 character length strong passwords and changed all of my account passwords, even the SQL sa user. I also enabled the auto ban feature of FileZillaServer (my FTP server) My questions: 1) how can i detect this kind of thing better? 2) how can i protect my server from unauthorized access better? PS: I'm a software dev, not a sysadmin so please mind my server security idiot-ness-ness

• Rails app deployment challenge, not finding database table in production.log

  - by Stefan M

  I'm trying to setup PasswordPusher as my first ruby app ever. Building and running the webrick server as instructed in README works fine.

• Win2008/IIS7/fx2.0 - 500.19 error

  - by Keith Barrows

  I installed new boxes at the beginning of the week. 1) Web Server on Win2008 x64, IIS 7 + all updates 2) DB Server on Win2008 x64, SQL 2008 Ent + all updates I configured my websites, set up host headers and DNS entries, worked through some problems on my handlers and finally got it all running Wednesday morning. Our team has been using it since then. This morning I came in and everyone of us is getting a 500 error. Error Summary HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification Unknown Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\RivWorks\dev\web.config Requested URL http://dev.rivworks.com:80/login.aspx Physical Path Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More InformationThis error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error. I’ve gone through the KB articles, made sure IIS_IUSRS had read permissions and am now stumped. What bothers me is IIS is looking in \?\C:\ instead of just C:. What is happening? TIA

• ospfd over an OpenVPN link - strange error in logs

• "Server Unavailable" and removed permissions on .NET sites after Windows Update

  - by tags2k

  Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.
