• Abnormal hangs and restarts Ubuntu 8.04

  - by jai-ho

  Hi, I am using Ubuntu 8.04 LTS and seeing the following behaviors: The system hangs after a while and becomes completely unresponsive. The system sometimes restarts itself ! Can you please help me identify what is the problem? Also please mention where should I look for the possible cause of this error. Thanks.

• External USB HD issues with a twist (works on Windows7 but not XP)

  - by Eruditass

  I have this older external USB HD, 160 GB. I was using it to copy my Steam games to another computer. On the source computer, Windows 7 64-bit, everything worked fine. Drive reported no errors, had no hiccups, etc. Plugging it into the Windows XP 32-bit computer, it worked fine for looking through the files, moving files around on it (no real reading/writing, just modifying the filesystem table). However, when copying files from it to my internal HD, after a couple seconds to tens of minutes (seemingly random times), the USB device becomes unrecognized and it reports a delayed write error. Events in system log go like this, chronologically: (number times displayed)xSource (Event ID): "message" 2xdisk (51): An error was detected on device \Device\Harddisk1\D during a paging operation. 1xftdisk (57): The system failed to flush data to the transaction log. Corruption may occur. 1xApplication popup (26): Windows - Delayed Write Failed : Windows was unable to save all the data for the file E:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. 1xntfs (50): {Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. These repeat for a while, then there is 10+ disk messages or ftdisk messages. Other notes: This occurs on random files at random times. This problem cannot be replicated on the Windows 7 source machine when copying from the HD to a different location on its local disk chkdsk /f was run and found no errors. chkdsk /f/r has the delayed write issue. drive was set to quick removal. Setting to performance in device manager yielded same result I am not writing anything to the USB external drive, so I am not sure why there is even a delayed write error (writing file access times?) local Windows XP was chkdsk'd without problems Windows XP machine has no problems with other USB HD's Various USB ports were attempted Rebooting did not help Occurs with SyncToy as well as windows explorer SMART status is good on both local drive and the external one Lack of gaming is making me cranky

• Java: Reading a pdf file from URL into Byte array/ByteBuffer in an applet.

  - by Pol

  I'm trying to figure out why this particular snippet of code isn't working for me. I've got an applet which is supposed to read a .pdf and display it with a pdf-renderer library, but for some reason when I read in the .pdf files which sit on my server, they end up as being corrupt. I've tested it by writing the files back out again. I've tried viewing the applet in both IE and Firefox and the corrupt files occur. Funny thing is, when I trying viewing the applet in Safari (for Windows), the file is actually fine! I understand the JVM might be different, but I am still lost. I've compiled in Java 1.5. JVMs are 1.6. The snippet which reads the file is below. public static ByteBuffer getAsByteArray(URL url) throws IOException { ByteArrayOutputStream tmpOut = new ByteArrayOutputStream(); URLConnection connection = url.openConnection(); int contentLength = connection.getContentLength(); InputStream in = url.openStream(); byte[] buf = new byte[512]; int len; while (true) { len = in.read(buf); if (len == -1) { break; } tmpOut.write(buf, 0, len); } tmpOut.close(); ByteBuffer bb = ByteBuffer.wrap(tmpOut.toByteArray(), 0, tmpOut.size()); //Lines below used to test if file is corrupt //FileOutputStream fos = new FileOutputStream("C:\\abc.pdf"); //fos.write(tmpOut.toByteArray()); return bb; } I must be missing something, and I've been banging my head trying to figure it out. Any help is greatly appreciated. Thanks. Edit: To further clarify my situation, the difference in the file before I read then with the snippet and after, is that the ones I output after reading are significantly smaller than they originally are. When opening them, they are not recognized as .pdf files. There are no exceptions being thrown that I ignore, and I have tried flushing to no avail. This snippet works in Safari, meaning the files are read in it's entirety, with no difference in size, and can be opened with any .pdf reader. In IE and Firefox, the files always end up being corrupted, consistently the same smaller size. I monitored the len variable (when reading a 59kb file), hoping to see how many bytes get read in at each loop. In IE and Firefox, at 18kb, the in.read(buf) returns a -1 as if the file has ended. Safari does not do this. I'll keep at it, and I appreciate all the suggestions so far.

• HttpWebResponse get mixed up when used inside multiple threads

  - by Holli

  In my Application I have a few threads who will get data from a web service. Basically I just open an URL and get an XML output. I have a few threads who do this continuously but with different URLs. Sometimes the results are mixed up. The XML output doesn't belong to the URL of a thread but to the URL of another thread. In each thread I create an instance of the class GetWebPage and call the method Get from this instance. The method is very simple and based mostly on code from the MSDN documentation. (See below. I removed my error handling here!) public string Get(string userAgent, string url, string user, string pass, int timeout, int readwriteTimeout, WebHeaderCollection whc) { string buffer = string.Empty; HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(url); if (!string.IsNullOrEmpty(userAgent)) myWebRequest.UserAgent = userAgent; myWebRequest.Timeout = timeout; myWebRequest.ReadWriteTimeout = readwriteTimeout; myWebRequest.Credentials = new NetworkCredential(user, pass); string[] headers = whc.AllKeys; foreach (string s in headers) { myWebRequest.Headers.Add(s, whc.Get(s)); } using (HttpWebResponse myWebResponse = (HttpWebResponse)myWebRequest.GetResponse()) { using (Stream ReceiveStream = myWebResponse.GetResponseStream()) { Encoding encode = Encoding.GetEncoding("utf-8"); StreamReader readStream = new StreamReader(ReceiveStream, encode); // Read 1024 characters at a time. Char[] read = new Char[1024]; int count = readStream.Read(read, 0, 1024); int break_counter = 0; while (count > 0 && break_counter < 10000) { String str = new String(read, 0, count); buffer += str; count = readStream.Read(read, 0, 1024); break_counter++; } } } return buffer; As you can see I have no public properties or any other shared resources. At least I don't see any. The url is the service I call in the internet and buffer is the XML Output from the server. Like I said I have multiple instances of this class/method in a few threads (10 to 12) and sometimes buffer does not belong the the url of the same thread but another thread.

• Haskell data serialization of some data implementing a common type class

  - by Evan

  Let's start with the following data A = A String deriving Show data B = B String deriving Show class X a where spooge :: a -> Q [ Some implementations of X for A and B ] Now let's say we have custom implementations of show and read, named show' and read' respectively which utilize Show as a serialization mechanism. I want show' and read' to have types show' :: X a => a -> String read' :: X a => String -> a So I can do things like f :: String -> [Q] f d = map (\x -> spooge $ read' x) d Where data could have been [show' (A "foo"), show' (B "bar")] In summary, I wanna serialize stuff of various types which share a common typeclass so I can call their separate implementations on the deserialized stuff automatically. Now, I realize you could write some template haskell which would generate a wrapper type, like data XWrap = AWrap A | BWrap B deriving (Show) and serialize the wrapped type which would guarantee that the type info would be stored with it, and that we'd be able to get ourselves back at least an XWrap... but is there a better way using haskell ninja-ery? EDIT Okay I need to be more application specific. This is an API. Users will define their As, and Bs and fs as they see fit. I don't ever want them hacking through the rest of the code updating their XWraps, or switches or anything. The most i'm willing to compromise is one list somewhere of all the A, B, etc. in some format. Why? Here's the application. A is "Download a file from an FTP server." B is "convert from flac to mp3". A contains username, password, port, etc. information. B contains file path information. A and B are Xs, and Xs shall be called "Tickets." Q is IO (). Spooge is runTicket. I want to read the tickets off into their relevant data types and then write generic code that will runTicket on the stuff read' from the stuff on disk. At some point I have to jam type information into the serialized data.

• C# - periodic data reading and Thread.Sleep()

  - by CaldonCZE

  Hello, my C# application reads data from special USB device. The data are read as so-called "messages", each of them having 24 bytes. The amount of messages that must be read per second may differ (maximal frequency is quite high, about 700 messages per second), but the application must read them all. The only way to read the messages is by calling function "ReadMessage", that returns one message read from the device. The function is from external DLL and I cannot modify it. My solution: I've got a seperate thread, that is running all the time during the program run and it's only job is to read the messages in cycle. The received messages are then processed in main application thread. The function executed in the "reading thread" is the following: private void ReadingThreadFunction() { int cycleCount; try { while (this.keepReceivingMessages) { cycleCount++; TRxMsg receivedMessage; ReadMessage(devHandle, out receivedMessage); //...do something with the message... } } catch { //... catch exception if reading failed... } } This solution works fine and all messages are correctly received. However, the application consumes too much resources, the CPU of my computer runs at more than 80%. Therefore I'd like to reduce it. Thanks to the "cycleCount" variable I know that the "cycling speed" of the thread is about 40 000 cycles per second. This is unnecessarily too much, since I need to receive maximum 700 messagges/sec. (and the device has buffer for about 100 messages, so the cycle speed can be even a little lower) I tried to reduce the cycle speed by suspending the thread for 1 ms by Thread.Sleep(1); command. Of course, this didn't work and the cycle speed became about 70 cycles/second which was not enough to read all messages. I know that this attempt was silly, that putting the thread to sleep and then waking him up takes much longer than 1 ms. However, I don't know what else to do: Is there some other way how to slow the thread execution down (to reduce CPU consumption) other than Thread.Sleep? Or am I completely wrong and should I use something different for this task instead of Thread, maybe Threading.Timer or ThreadPool? Thanks a lot in advance for all suggestions. This is my first question here and I'm a beginner at using threads, so please excuse me if it's not clear enough.

• high load average, high wait, dmesg raid error messages (debian nfs server)

• LDAP change user pass on client

  - by Sean

  I am trying to allow ldap users to change their password on client machines. I have tried pam every which way I can think of /etc/ldap.conf & /etc/pam_ldap.conf, as well. At this point I'm stuck. Client: Ubuntu 11.04 Server: Debian 6.0 The current output is this: sobrien4@T-E700F-1:~$ passwd passwd: Authentication service cannot retrieve authentication info passwd: password unchanged /var/log/auth.log gives this during the command: May 9 10:49:06 T-E700F-1 passwd[18515]: pam_unix(passwd:chauthtok): user "sobrien4" does not exist in /etc/passwd May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: ldap_simple_bind Can't contact LDAP server May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: reconnecting to LDAP server... May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: ldap_simple_bind Can't contact LDAP server getent passwd |grep sobrien4 (note keeping short since testing with that account, however it outputs all ldap users): sobrien4:Ffm1oHzwnLz0U:10000:12001:Sean O'Brien:/home/sobrien4:/bin/bash getent group shows all ldap groups. /etc/pam.d/common-password (Note this is just the most current, I have tried a lot of different options): password required pam_cracklib.so retry=3 minlen=8 difok=3 password [success=1 default=ignore] pam_unix.so use_authtok md5 password required pam_ldap.so use_authtok password required pam_permit.so Popped open wireshark as well, the server & client are talking. I have the password changing working on the server. I.E. the server that runs slapd, I can log in with the ldap user and change the passwords. I tried copying the working configs from the server initially and no dice. I also tried cloning it, and just changing ip & host, and no go. My guess is that the client is not authorized by ip or hostname to change a pass. Pertaining to the slapd conf, I saw this in a guide and tried it: access to attrs=loginShell,gecos by dn="cn=admin,dc=cengineering,dc=etb" write by self write by * read access to * by dn="cn=admin,dc=cengineering,dc=etb" write by self write by * read So ldap seems to be working okay, just can't change the password.

• Linux software raid robustness

  - by Waxhead

  I have a 4 disk 5TB raid5 setup where a disk is showing signs of going down the drain. It is reporting media errors and from dmesg I can see that several read errors are corrected. smartctl does report "notifications" but no panic so far. Since new disks are rather expensive at the moment I am starting to pondering exactly how robust the linux md layer is. I would appreciate if someone could shed some light on how md actually deals with disk errors. For example how does md deal with write and read errors - what does it (really) take for disk to be rejected from an array. I also read that recently md got support for mapping out bad blocks. Does this mean that the read errors I've had would have been mapped out if I where running kernel 3.1 or would md still try to "work on them" to make them usable.

  I have migrated a file based Xen guest to LVM using dd bs=1M if=/dev/zero of=/dev/vg00/vm10 qemu-img convert ~/vm10.qcow2 -O raw /dev/vg00/vm10 and changed the Xen domain file for the VM to use the LV instead of the old file. The VM boots up, and now on the Xen host would I like to make a snapshot of the running VM. # lvcreate --size 10G --snapshot --name vm10-snapshot /dev/vg00/vm10 Logical volume "vm10-snapshot" created # mount /dev/vg00/vm10-snapshot /mnt/snapshot/ mount: you must specify the filesystem type # dmesg |tail EXT3 FS on dm-3, internal journal EXT3-fs: mounted filesystem with ordered data mode. hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-4. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-2. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock For some reason it can't see it is an EXT3 filesystem.

• How do I deny access to everybody but me in Windows 7?

  - by GregH

  I am trying to set up a file server on my my Windows 7 Pro system at home. I set up one common "Share" folder that I have shared/published. Within the share folder I want to have individual folders for me and my wife...that is only I can read/write my folder and only my wife can read/write to her folder and neither of us can read the contents of the other person's folder. Then I want to have a "public" folder where we can both read/write to contents of the folder as well as any sub-folders created, but my "kids" account can only read from this folder and sub folders. It seems really confusing to set up something like this and it really shouldn't. I am really confused between the "allow", "deny", and dimmed check boxes in the security tab. It seems that if I "Deny" access to "Everyone" on my private folder, then I don't even have access to it. Windows security seems backwards from the rest of the world's security models. If I am in two groups and I deny access to one of the groups but allow access to the other group then Windows security denies me access as I am in one of the groups that has access disallowed. Very confusing.

• Slow Windows Explorer on Windows 7

  - by MadBoy

  I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds). I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document). I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things. I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas? Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious. Below are stats during normal usage with a lots of programs open: - Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB - CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4) HD Tune Pro: OCZ-VERTEX3 MI Benchmark Test capacity: full Read transfer rate Transfer Rate Minimum : 363.9 MB/s Transfer Rate Maximum : 505.5 MB/s Transfer Rate Average : Access Time : Burst Rate : CPU Usage : HD Tune Pro: OCZ-VERTEX3 MI File Benchmark Drive C: Transfer rate test File Size: 500 MB Sequential read 484102 KB/s Sequential write 444714 KB/s Random read 7779 IOPS Random write 16888 IOPS Random read (queue depth = 32) 73007 IOPS Random write (queue depth = 32) 69790 IOPS HD Tune Pro: OCZ-VERTEX3 MI Random Access Test capacity: full Read test Transfer size operations / sec avg. access time max. access time avg. speed 512 bytes 3260 IOPS 0.306 ms 2.106 ms 1.592 MB/s 4 KB 4161 IOPS 0.240 ms 2.006 ms 16.256 MB/s 64 KB 2382 IOPS 0.419 ms 2.367 ms 148.934 MB/s 1 MB 449 IOPS 2.225 ms 4.197 ms 449.407 MB/s Random 809 IOPS 1.235 ms 6.551 ms 410.527 MB/s HD Tune Pro: OCZ-VERTEX3 MI Extra Tests Test capacity: full Random seek 3975 IOPS 0.252 ms 1.941 MB/s Random seek 4 KB 4245 IOPS 0.236 ms 16.583 MB/s Butterfly seek 4086 IOPS 0.245 ms 1.995 MB/s Random seek / size 64 KB 3812 IOPS 0.262 ms 58.606 MB/s Random seek / size 8 MB 120 IOPS 8.348 ms 485.737 MB/s Sequential outer 4524 IOPS 0.221 ms 282.721 MB/s Sequential middle 4429 IOPS 0.226 ms 276.818 MB/s Sequential inner 5504 IOPS 0.182 ms 344.000 MB/s Burst rate 4472 IOPS 0.224 ms 279.475 MB/s

• Practical RAID Performance?

  - by wag2639

  I've always thought the following to be a general rule of thumb for RAID: RAID 0: Best performance for READ and WRITE from stripping, greatest risk RAID 1: Redundant, decent for READ (I believe it can read from different parts of a file from different hard drives), not the best for WRITE RAID 0+1 (01): combines redundancy of RAID 1 with performance of RAID 0 RAID 1+0 (10): slightly better version of RAID 0+1 RAID 5: good READ performance, bad WRITE performance, redundant IS THIS ASSUMPTION CORRECT? (and how do they compare to a JBOD setup for R/W IO performance) Are certain practical RAID setups better for different applications: gaming, video editing, database (Acccess or SQL)? I was thinking about hard disk drives but does this apply to solid state drives as well?

• Windows Server 2003 R2 Standard: Locks MS Office files, but not Adobe .AI and .PSD files?

  - by Bruce Garlock

  We have some shares setup on a Windows 2003 R2 server, and the MS Office files people save behave properly: The first person to open the file gets read/write, and the second person to open the file while the first person still has the file open, gets a read-only version. This is not true for the graphics files, like Adobe Illustrator .AI files, and Photoshop .PSD files. Anyone who goes to open these files has full read/write, even if someone else is already working on the file! This has lead to numerous file corruption issues, as well as other lost work, since it always saves the last changes to the file. How do we get Windows to properly lock these files so when someone is working on a file, and someone else wants to open one, they get read-only access? Many thanks, Bruce

• How to install a private user script in Chrome 21+?

  - by Mathias Bynens

  In Chrome 20 and older versions, you could simply open any .user.js file in Chrome and it would prompt you to install the user script. However, in Chrome 21 and up, it downloads the file instead, and displays a warning at the top saying “Extensions, apps, and user scripts can only be added from the Chrome Web Store”. The “Learn More” link points to http://support.google.com/chrome_webstore/bin/answer.py?hl=en&answer=2664769, but that page doesn’t say anything about user scripts, only about extensions in .crx format, apps, and themes. This part sounded interesting: Enterprise Administrators: You can specify URLs that are allowed to install extensions, apps, and themes directly through the ExtensionInstallSources policy. So, I ran the following commands, then restarted Chrome and Chrome Canary: defaults write com.google.Chrome ExtensionInstallSources -array "https://gist.github.com/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://gist.github.com/*" Sadly, these settings only seem to affect extensions, apps, and themes (as it says in the text), not user scripts. (I’ve filed a bug asking to make this setting affect user scripts as well.) Any ideas on how to install a private user script (that I don’t want to add to the Chrome Web Store) in Chrome 21+? Update: The problem was that gist.github.com’s raw URLs redirect to a different domain. So, use these commands instead: # Allow installing user scripts via GitHub or Userscripts.org defaults write com.google.Chrome ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" This works!

• Linux not buffering block I/O when the device is not "in use" (i.e. mounted)

  - by Radek Hladík

  I am installing new server and I've found an interesting issue. The server is running Fedora 19 (3.11.7-200.fc19.x86_64 kernel) and is supposed to host a few KVM/Qemu virtual servers (mail server, file server, etc..). The HW is Intel(R) Xeon(R) CPU 5160 @ 3.00GHz with 16GB RAM. One of the most important features will be Samba server and we have decided to make it as virtual machine with almost direct access to the disks. So the real HDD is cached on SSD (via bcache) then raided with md and the final device is exported into the virtual machine via virtio. The virtual machine is again Fedora 19 with the same kernel. One important topic to find out is whether the virtualization layer will not introduce high overload into disk I/Os. So far I've been able to get up to 180MB/s in VM and up to 220MB/s on real HW (on the SSD disk). I am still not sure why the overhead is so big but it is more than the network can handle so I do not care so much. The interesting thing is that I've found that the disk reads are not buffered in the VM unless I create and mount FS on the disk or I use the disks somehow. Simply put: Lets do dd to read disk for the first time (the /dev/vdd is an old Raptor disk 70MB/s is its real speed): [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 36.8038 s, 71.2 MB/s Buffers: 14444 kB Rereading the data shows that they are cached somewhere but not in buffers of the VM. Also the speed increased to "only" 500MB/s. The VM has 4GB of RAM (more that the test file) [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 5.16016 s, 508 MB/s Buffers: 14444 kB [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 5.05727 s, 518 MB/s Buffers: 14444 kB Now lets mount the FS on /dev/vdd and try the dd again: [root@localhost ~]# mount /dev/vdd /mnt/tmp [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 4.68578 s, 559 MB/s Buffers: 2574592 kB [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 1.50504 s, 1.7 GB/s Buffers: 2574592 kB While the first read was the same, all 2.6GB got buffered and the next read was at 1.7GB/s. And when I unmount the device: [root@localhost ~]# umount /mnt/tmp [root@localhost ~]# cat /proc/meminfo | grep Buffers Buffers: 14452 kB [root@localhost ~]# dd if=/dev/vdd of=/dev/null bs=256k count=10000 ; cat /proc/meminfo | grep Buffers 2621440000 bytes (2.6 GB) copied, 5.10499 s, 514 MB/s Buffers: 14468 kB The bcache was disabled while testing and the results are same on faster (newer) HDDs and on SSD (except for the initial read speed of course). To sum it up. When I read from the device via dd first time, it gets read from the disk. Next time I reread it gets cached in the host but not in the guest (thats actually the same issue, more on that later). When I mount the filesystem but try to read the device directly it gets cached in VM (via buffers). As soon as I stop "using" it, buffers are discarded and the device is not cached anymore in the VM. When I looked into buffers value on the host I realized that the situation is the same. The block I/O gets buffered only when the disk is in use, in this case it means "exported to a VM". On host, after all the measurement done: 3165552 buffers On the host, after the VM shutdown: 119176 buffers I know it is not important as the disks will be mounted all the time but I am curious and I would like to know why it is working like this.

Could something else be causing the problem? I've scheduled a smartctl -t long test that will finish in a couple of hours. I hope this will give me some more info.

Today it started throwing out errors like: kernel: ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen kernel: ata2.00: cmd b0/d0:01:00:4f:c2/00:00:00:00:00/00 tag 0 pio 512 in kernel: res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) kernel: ata2.00: status: { DRDY } kernel: ata2: hard resetting link kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) kernel: ata2.00: max_sectors limited to 256 for NCQ kernel: ata2.00: max_sectors limited to 256 for NCQ kernel: ata2.00: configured for UDMA/133 kernel: sd 1:0:0:0: timing out command, waited 7s kernel: ata2: EH complete kernel: SCSI device sda: 976773168 512-byte hdwr sectors (500108 MB) kernel: sda: Write Protect is off kernel: SCSI device sda: drive cache: write back All day long it has been in load higher than 10-15. I am monitoring it with atop and it gives some bizarre readings: DSK | sda | busy 100% | read 2 | write 208 | KiB/r 16 | KiB/w 32 | MBr/s 0.00 | MBw/s 0.65 | avq 86.17 | avio 47.6 ms | DSK | sdb | busy 1% | read 10 | write 117 | KiB/r 17 | KiB/w 5 | MBr/s 0.02 | MBw/s 0.07 | avq 4.86 | avio 1.04 ms | I frankly don't understand why only sda is taking all the hit. I do have one process that is constantly writing with 1-2megs but what the hell.. 100% iowait?

• How to keep variable preserve while running script through ssh

  - by Ali Raza

  I am trying to run while loop with read through ssh: #!/bin/bash ssh [email protected] "cat /var/log/syncer/rm_filesystem.log | while read path; do stat -c \"%Y %n\" "$path" >> /tmp/fs_10.10.10.10.log done" But the issue is my variable $path is resolving on my localhost where as I want to resolve it on remote host so that it can read file on remote host and take stat of all folder/files listed in "rm_filesystem.log"

• Windows Server 2003 Hacked - Files Being Uploaded

  - by jreedinc

  Blank directories are being created on my Windows Server 2003 virtual server with sub directories that are weird (for example: "88ÿ ÿ ÿÿþþ þþ13þ"). It looks like they are uploading bootlegged DVDs and pirated software. All of my bandwidth and file space is being eaten up. Could this be a shared permissions issue? Where should I look to further investigate this? My security permissions for the directory that is being hit are as followed: Administrators - ALL GRANTED IIS_WPG - Read & Execute, List Folder Contents, Read Internet Guest - DENY SYSTEM - ALL GRANTED Users - Read & Execute, List Folder Contents, Read My Event Viewer is showing many Logon/Logoff with NO IP?

• CentOS tftp server is broken

  - by Mike Pennington

  I'm trying to run tftpd from xinetd on CentOS 6; however, I can only tftp from localhost. I have a file in /opt/tftpboot/fw.test.conf that I can retrieve if I tftp to localhost: [mpenning@localhost ~]$ tftp localhost tftp> get fw.test.conf tftp> quit [mpenning@localhost ~]$ ls fw.test.conf [mpenning@localhost ~]$ However, I cannot receive this file if I tftp to eth1 on this server (the address on eth1 is 172.16.1.4). [mpenning@localhost ~]$ sudo tshark -i eth1 udp and host 172.16.1.5 Running as user "root" and group "root". This could be dangerous.
