• Postfix cannot deliver mail to Cyrus mailbox on Ubuntu 11.10 server

  - by user105804

  I have installed and configured Postfix and Cyrus IMAP server with webcyradm according to this document - http://www.delouw.ch/linux/Postfix-Cyrus-Web-cyradm-HOWTO/html/index.html . I can access webcyradm interface, I can create new domains and new users, and I can login via IMAP after creating the user account. However, Postfix fails to deliver mail to cyrus mailboxes. Mail log contains errors shown below. Installing any IMAP server other than cyrus is not an option because it is needed by the web application. Please advise me how to make Postfix deliver email to cyrus mailboxes. The solution should not necessary include web-cyradm, but there should be a web interface for managing mail domains and mailboxes as user-friendly as possible.

• Copy past speed very slow for a large number of tiny files on Windows but not on linux

  - by Arno2501

  I've got this folder which contains 15'000 of tiny images (around 400 bytes each). If I copy past this folder on my laptop (Windows 7, i7 latest gen, superfast ssd) it takes about 30 seconds (yes for 7 megs !!!) the average transfer rate is 400 KBytes / second which is so slow. I mean my usual transfer rate is more like hundreds of MBytes per second !!! I get the same problem on my servers (Windows 2003, 2008 /r2) and on every Windows box that I could get my hands on. On the other hand if I do the same on a linux box (debian base, Ext3 FS) (which runs on the same SAN than all the windows servers I've tested) It's nearly instantaneous !!! I'm pretty sure the size / number of the files may stress such filesystem more than another but such differences !? Why is that ? Why is it so slow on the windows boxes (more that 30 sec for 7 MB) and so fast on the linux ones (one sec or so) (I mean this was not a hardlink that I've created it was a true copy). Is it a normal behaviour or something unusual ?

• Ubuntu 10.04 freezing and Ctrl + Alt + Backspace does nothing but music keeps playing

  - by Bryce Thomas

  I'm having intermittent problems where the screen will freeze in Ubuntu. I've tried using Ctrl + Alt + Backspace to restart the X-server, though this does nothing. When the freeze occurs, there's a small square of black dashes around the mouse pointer - maybe 1 inch in size. These dashes look a lot like a 2d barcode. The rest of the screen looks normal, but I can't move the mouse and none of the keyboard shortcuts work to do anything. However, music that I begin playing before the freeze continues to play, which seems to indicate it hasn't stalled up completely. I've noticed a similar freezing problem when I'm using Windows 7. That is, I see the same barcode like dashes around the mouse pointer when it freezes up. So I'm guessing it's either a driver or hardware problem. I thought if it was a hardware problem though, the whole computer might stop working (i.e. music would stop playing)? The video card I am using is an Nvidia, and I believe it's in the 7600 range. In Ubuntu I have the drivers for the card set to the latest available (proprietary). Ideally I'd like to be able to continue using the proprietary drivers. Is there any known issues with the drivers for this model graphics card, or has anyone experienced the same problem and knows how to fix it?

• TCP Server Memory management: #Connections Vs. #Requests

  - by Andrew

  Given that, there is no theoretical limit to number of concurrent TCP connections a Windows 2008 server can handle. Only thing will happen is, with each connection there will be memory consumption in server. Unfortunately, memory is not unlimited (and I want to utilize only physical memory). For example, lets say we've 2GB server memory. Now there are two extreme cases: Case 1: If we've allocated 64KB buffer for each connection (only to receive incoming request), then 32768 connections can consume all the 2GB of memory. This will not leave any memory to queue/process incoming requests from those connections. Case 2: On the other hand, lets say a single (or very few) connections continuously keeps sending request buffers (for example, video streaming from one connection to other) and server cannot process them within time, those buffers will get piled up in server and eventually will occupy most of the servers memory. And it will not leave any memory for new connection thereafter. This is the real dilemma in server design bugging me badly for last many days. If I can decide on max size of request buffer per connection and max number of requests to allow in queue per connection. Then, based on available server memory, it will then automatically set limit on max number of concurrent connections. How to decide on these limits to achieve best performance and throughput? I am just looking for perfect utilization of server resources. Are there any standard guidelines or empirical data available with someone who can share with me please.

• How to export SQL Server data from corrupted database (with disk write error)

  - by damitamit

  IT realised there was a disk write error on our production SQL Server 2005 and hence was causing the backups to fail. By the time they had realised this the nightly backup was old, so were not able to just restore the backup on another server. The database is still running and being used constantly. However DBCC CheckDB fails. Also the SQL Server backup task fails, Copy Database fails, Export Data Wizard fails. However it seems all the data can be read from the tables (i.e using bcp etc) Another observation I have made is that the Transaction Log is nearly double the size of the Database. (Does that mean all the changes arent being written to the MDF?) What would be the best plan of attack to get the database to a state where backups are working and the data is safe? Take the database offline and use the MDF/LDF to somehow create the database on another sql server? Export the data from the database using bcp. Create the database (use the Generate Scripts function on the corrupt db to create the schema on the new db) on another sql server and use bcp again to import the data. Some other option that is the right course of action in this situation? The IT manager says the data is safe as if the server fails, the data can be restored from the mdf/ldf. I'm not sure so insisted that we start exporting the data each night as a failsafe (using bcp for example). IT are also having issues on the hardware side of things as supposedly the disk error in on a virtualized disk and can't be rebuilt like a normal raid array (or something like that). Please excuse my use of incorrect terminology and incorrect assumptions on how Sql Server operates. I'm the application developer and have been called to help (as it seems IT know less about SQL Server than I do). Many Thanks, Amit

• Fix Video timelines

  - by Josh

  So, I have been going through and riping all of my DVD's and it seems that the way to get the highest quality out of these is to have DVD Shrink de-encrypt, rip, and decompress, the DVD's. After that I usually end up with a high quality (high size) set of .vob files in a classic DVD structure. Then I use a python script that I wrote to automate the process of finding the title sequence and then combining all of the title sequences' .vob files together into one file(similar to the "copy /b" command in windows), and then changing the extension to .mpg (a more widely supported format then .vob). This allows me to get a high quality rip in about 40 min. The problem comes in playing the files. I need all of the ripped dvd's to play on my media computer using windows media center but windows media center (and vlc for that matter) all think that the video files are anywhere from 5 min. to 0 min. which is not a problem (the video will still play all the way through) but if you want to pause it, when it is unpaused the video will start all the way over (Also fast forward and rewind don't work). I suspect that it is something wrong with the way the timeline is encoded in the video file, various forums on the internet recommended using virtualdub to fix the errors. But when I try to open the file virtual dub says that the file is not in mpeg-1 encoding and may be in mpeg-2. Is there any way to fix this? PS: I am aware that there was a similar question but it hasn't had any activity for 2 months and is dealing more with wmv files.

• Change Windows 7 Explorer's Details Pane limits

  - by Paul

  For some reason, MS decided to completely kill the status bar's functionality in Win7 (and maybe Vista, but I don't know for sure). I have tried all possible options such as Classic Shell and so on. Basically, the one thing I miss most is seeing at a glance the total size of my selected files. I know I can press Alt+Enter or whatever, but that's not the point. The point is that the so-called 'details' pane stops providing details if more than 15 files are selected! WTH? Cannot understand the reason behind such a stupid arbitrary limit, that doesn't seem to be user-configurable at all. Anyway, what I'm looking for is a way to change that limit, either via the registry or otherwise. If changing the limit isn't possible, would it be possible for some programming genius to create a very small optimized light-weight non resource-hungry (you get the idea!) program whose sole purpose will be to automatically click the "Show more details..." link in the details pane after every file selection? For bonus points, the program should wait for a second or two after file selection is complete to do this, so that selecting multiple files in quick succession doesn't hit the HDD repeatedly. Any takers for the challenge? :)

• VMWare Raw Device Mapping Not Working

  - by George H. Lenzer

  While I'm waiting for VMWare support to get back to me, I thought I'd ask here. I have a 400 gig LUN presented from a fiber channel SAN to my VMWare host. It's legacy from another virtualization platform and I need to keep it as is to avoid a long period of downtime. I formatted my VMFS3 datastore with 4 meg blocks to allow up to 1 TB disks. Then I tried adding my 400 gig disk as a raw device in physical compatibility mode. I get the error: "File is larger than the maximum size supported by datastore 'Base Test'. [Base Test]VMTEST01/VMTEST01_2.vmdk Originally I had the VMFS datastore formatted with 1 meg blocks which was the cause of this problem since the largest disk allowed would be 256 gigs. But I deleted the data store and then reformatted with 4 megs blocks. I've also tried using virtual compatibility mode for the raw device but it still fails. Does anyone have any suggestions? I've been waiting for a little over a week for VMWare, but that's fine because I'm not yet a paying customer. I'm still in the eval phase.

• lsof not showing what port a proc is listening on

  - by ericslaw

  I have many processes on a box listening on several ports. I am trying to map ports to pids. The problem is that lsof is not telling me what ports belong to which process. Given an apache listening on port 80, I can see it listening via netstat: user@host% netstat -an|grep LISTEN|grep 80 *.80 *.* 0 0 49152 0 LISTEN But when I try to map port 80 to a pid I get nothing: user@host% lsof -iTCP:80 -t When I try seeing what sockets that specific pid is using I get: user@host% lsof -lnP -p31 -a -i COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME libhttpd. 31 0 15u IPv4 0x6002d970b80 0t0 TCP *:65535 (LISTEN) Notice the *:65535 in the NAME column. Does anyone know why lsof is not reporting the port in use? I am running as root. I am using a mix of lsof and os versions: lsof v4.77 on Solaris10 sparc lsof v4.72 on Redhat4.2 etc I know that linux solutions can use "netstat -p", so I guess I'm only looking for why solaris isn't working, but I find lsof is frequently silent and not showing me expected data.

• Determining the Source of a Given File System Mount on Unix [migrated]

  - by phobos51594

  Background Recently I have run into a bit of a snag on my home FreeBSD server. I recently upgraded it to the latest stable release, and I have noticed some strange behavior with the /var partition. Originally, I had the system configured such that /var had its own partition with /var/run and /var/log in memory disks (/tmp, too). After the upgrade, I notice there is a new, fourth memory disk mounting directly to /var that I had not set up manually and is not in my fstab. It is only 28 megs or so in size and is causing problems when trying to update my ports collection. The ramdisk mounts atuomagically at boot and cannot be unmounted while in multi-user mode. If I drop to single user mode, I am able to unmount it without issue, however rebooting causes it to pop right back up. System specifications have been included at the end of the post. Question Is there any way to determine exactly what is mounting a given memory disk (or any filesystem, for that matter) after it has been mounted? Alternately, does anybody have any ideas what might have caused the new /var ramdisk to pop up?

• Loads of memory in "standby" on Windows Server 2008 R2

  - by Jaap

  In our SharePoint farm, our Web Front End servers all have loads of memory in "standby" mode, meaning very little is available for our IIS worker process. We have 32 GB of RAM in each of the boxes, and standby memory will creep up to about 28 GB, whereas the IIS worker process only seems to be using about 2 GB. Also, we've seen the machine use the swap file extensively while this memory was in standby, so I am starting to think that this memory in standby mode is stopping IIS from using it, forcing it to swap to disk, causing more performance problems. I used SysInternals RamMap to indentify what is being kept in memory, and it was able to tell me that almost everything in standby memory is of type "Mapped File". When I sort the files listed under the file summary tab in RamMap by file size, the largest files (around a few hundred meg each) are IIS log files and SharePoint log files. I would like to understand which process is loading these files into standby memory and why they are not being released. When I do an iisreset, it does not release the memory. Any ideas? Thanks!

• Update a bootable OS X drive clone with rsync?

  - by Joe

  The question: is it possible to keep a boot-able backup drive clone of OS X updated with rsync? If rsync is not a viable option are there alternatives? The Setup: My situation is as shown above. One internal Samsung 840 SSD [120g] in use as my OS X 10.8 boot disk on a recent model Mac Mini. I have successfully cloned that drive with disk utility to a 125g partition of another HDD in an external USB 3 enclosure and at that point I am able to boot to it. The Goal: As my last system went out in a fiery blaze taking much valuable data with it, I have a new respect for a proper backup solution and really want to do this right. My goal is to achieve an automated differential backup/update from Disk A to Disk B while most importantly maintaining boot-ability on the external drive. And I would prefer to do this differentially to minimize stress on the drives. Hence rsync was the first thing to come to mind. What I have tried: following along with Jamie Zawinski's differential mac bootable backup solution running this manually initially worked - i tested it with only very miniscule file change and everything was fine / external booted and all. now after subsequent passes rsync fails throwing errors particularly relating to updating 'boot.efi' (not at the machine currently I will update the precise log message once I return home) is this a drive partition size issue? does rsync require more space? if it cant be done, are there any alternatives? i've heard whispers of dd

For Hotmail there are policies to prevent the email from being sent. I do this: echo "email content" | mail -s "blah" [email protected] And the email returns as undeliverable, the email does not even appear in the spam folder and I get this as a response: ----- Transcript of session follows ----- ... while talking to mx3.hotmail.com.: >>> MAIL From:<[email protected]> SIZE=685 <<< 550 DY-001 (BAY0-MC3-F8) Unfortunately, messages from 184.90.101.28 weren't sent. Please contact your +Internet service provider. You can tell them that Hotmail does not relay dynamically-assigned IP ranges. +You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. 554 5.0.0 Service unavailable So apparently hotmail doesn't like spammers so much, they they are blocking anything with a dynamically assigned IP range. Google does not do this. What is the easiest way to just get around this and send an email to hotmail and end up in their spam folder to be unblocked later by the user?

• Organizing automatically Windows Files and Folders

  - by Kiquenet

  For Windows only, Organizing the eleventy-billion files you've got stuffed into folders on your hard drive is very "hard". For example, I have one folder on my computer that I save all web downloads to, regardless of file type, size or purpose. Many of the files are only temporary downloads, for instance setup files of applications that I test, demonstration videos that I watch once or documents that I want to read. Some files on the other hand are there to stay, and I used to move them out of the download folder manually in the past. Another files in folders in my computer: many source code, tests, programs, tools, ... I need tecnology for organize billion files.

• Which upgrade path for disk IO bound postgres server?

  - by user41679

  Hi all, We currently have a Sun x4270 with 2xquad core Xeon Nehalmen 2.93ghz cores (16 threads), 72 gig of ram and 16 x 10k SAS disks split between the os raid 1, a partition for the Write Ahead Logs which is raid 10 and a partition for the database tables and indexes which is also raid 10, all xfs. I'm currently evaluating which path to go down in terms of upgrades. We'll be sharding the DB at some point soon, but for now I need to focus on hardware upgrades specifically. The machine is not CPU or memory bound at all at the moment, just IOWait is become an issue. The machine is mostly write access as we have a heavy caching layer. We're seeing about 300 write IOPS average on both the database partitions. We don't have any additional storage infrastructure like a Fiber Channel or ISCSI network. Budget isn't too much of a concern, something inline with the size of this server (i.e no $1m IBM machines) Space is ok on the DB side of things, we're running out obviously but there's also some reduction we can do. Additional space would be good though. My current thoughts are either: * ISCSI SAN, possible with 10Gbit network that has solid state acceleration. * FusionIO card / Sun F20 card (will the FusionIO card work in the Sun box? * DAS shelf (something like this http://www.broadberry.co.uk/das-direct-attached-storage-servers/cyberstore-224s-das) which a combination of 15k sas disks and some Intel X25-E drives for DB indexes etc) what would I need to put in the x4270 to add a DAS shelf? I think it's a SAS HBA card, do I have to use Sun's own card or will any PCI Express card work? Anything else??? what would you guys do from your experience? I appreciate it's a lot of questions, but I haven't expanded a DB machine for a number of years and the landscape has changed dramatically since then! Any advice or feedback would be very much appreciated. Let me know if there's anything else I can clarify. Thanks in advance!

• Recovering a mdadm+lvm+ext4 partition with read error

  - by bitwelder

  One of disks in my NAS has failed. The NAS is running Linux, and it uses mdadm + LVM technology for its filesystems. I do have backup for most of the contents, but not for the very last changes, and if possible, I'd like to recover that from this failing disk. The disk (a 'green drive' WD10EARS 1TB in size) throws this kind of errors: Oct 3 12:00:41 kernel: [ 3625.620000] ata5.00: read unc at 9453282 Oct 3 12:00:41 kernel: [ 3625.620000] lba 9453282 start 9453280 end 1953511007 Oct 3 12:00:41 kernel: [ 3625.620000] sde5 auto_remap 0 Oct 3 12:00:41 kernel: [ 3625.630000] ata5.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 Oct 3 12:00:41 kernel: [ 3625.630000] ata5.00: edma_err_cause=00000084 pp_flags=00000003, dev error, EDMA self-disable Oct 3 12:00:41 kernel: [ 3625.640000] ata5.00: failed command: READ FPDMA QUEUED Oct 3 12:00:41 kernel: [ 3625.650000] ata5.00: cmd 60/40:00:e0:3e:90/00:00:00:00:00/40 tag 0 ncq 32768 in Oct 3 12:00:41 kernel: [ 3625.650000] res 41/40:00:e2:3e:90/12:00:00:00:00/40 Emask 0x409 (media error) <F> Oct 3 12:00:41 kernel: [ 3625.660000] ata5.00: status: { DRDY ERR } However, while testing with 'dd', I noticed that if I skip the first 4kB, the read seems to be ok, i.e. a command like. dd if=/dev/sde5 of=dev/null bs=4k count=1000 skip=1 doesn't return any read error. Supposing that there is no other read failure in the rest of the disk, would I be able to recover this 900 GB partition (as I mentioned before, it's a 'linux raid autodetect' partition, that contains a a LVM2 volume that contains a ext4 filesystem) if I copy-clone the partition somewhere else, but the first 4kB?

• Windows Server 2012 Hyper-V very slow

  - by Matt Taylor

  I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

• Windows Network File Transfer to Samba server: “Are you sure you want to copy this file without its properties?”

  - by jimp

  I am transferring a lot of files to a new NAS based on OpenMediaVault, with the Samba 3.5.6 service running. I am transferring from Windows 7 64-bit to the NAS, and on some media files Windows is prompting about losing some property data across the transfer. I have never seen this before when transferring to Samba boxes I have built myself (vs this turnkey solution), so I'm guessing there must be a Samba setting I can change to preserve the file properties in question instead of permanently losing whatever they contain (Date Taken? Exposure? Flash Fired? etc). Or maybe I've just never encountered this before; I'm really not sure. I tried adding ea support = yes and store dos attributes = yes to the [global] section, but the problem remains. The Linux file system is ext4 mounted with user_xattr (full options: defaults,acl,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0) as Samba requires. Any ideas would be greatly appreciated. Thank you! Samba config: [global] workgroup = WORKGROUP server string = %h server include = /etc/samba/dhcp.conf dns proxy = no log level = 2 syslog = 2 log file = /var/log/samba/log.%m max log size = 1000 syslog only = yes panic action = /usr/share/samba/panic-action %d encrypt passwords = true passdb backend = tdbsam obey pam restrictions = yes unix password sync = no passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . pam password change = yes socket options = TCP_NODELAY IPTOS_LOWDELAY guest account = nobody load printers = no disable spoolss = yes printing = bsd printcap name = /dev/null unix extensions = yes wide links = no create mask = 0777 directory mask = 0777 use sendfile = no null passwords = no local master = yes time server = yes wins support = yes ea support = yes store dos attributes = yes Note: I found this related question, but it explains the loss due to the user trying to transfer from NTFS to FAT32.

• Distortion problem with Creative audio equalizer

  - by e-t172

  Hi, I have a problem with the Creative Console EQ, I don't know if it's fixable or not (is the EQ software or hardware on these cards?). Basically, I have enormous distortion with certain sounds in the 30 - 125 hz range. When this happens I get some sort of "frrzzzz" (sorry, I'm french and don't really know the correct english word for that) on top of the original sound. I have a Sound Blaster Audigy SE. I'm using the Daniel_K drivers, on Windows 7 Profesionnal x64. All the effects are disabled except EQ. Steps to reproduce Put the card in 24bit/96khz mode. The problem is also present with 16bit/48khz but seems to be less audible. In the Creative Console, use the following EQ: (full size) Play this sound at a reasonably high volume. You should hear distortion on the two "booms". Especially the second one. Disable Creative EQ. Play the sound in an application with an integrated EQ (e.g. foobar2000, ffdshow) using the same EQ parameters. There is no distortion. Conclusion: the Creative EQ is broken. Is anyone having the same problem? I'm also interested in the results with other Creative cards or even other brands soundcards with a similar EQ feature.
