• Linux Software RAID recovery

  - by Zoredache

  I am seeing a discrepancy between the output of mdadm --detail and mdadm --examine, and I don't understand why. This output mdadm --detail /dev/md2 /dev/md2: Version : 0.90 Creation Time : Wed Mar 14 18:20:52 2012 Raid Level : raid10 Array Size : 3662760640 (3493.08 GiB 3750.67 GB) Used Dev Size : 1465104256 (1397.23 GiB 1500.27 GB) Raid Devices : 5 Total Devices : 5 Preferred Minor : 2 Persistence : Superblock is persistent Seems to contradict this. (the same for every disk in the array) mdadm --examine /dev/sdc2 /dev/sdc2: Magic : a92b4efc Version : 0.90.00 UUID : 1f54d708:60227dd6:163c2a05:89fa2e07 (local to host) Creation Time : Wed Mar 14 18:20:52 2012 Raid Level : raid10 Used Dev Size : 1465104320 (1397.23 GiB 1500.27 GB) Array Size : 2930208640 (2794.46 GiB 3000.53 GB) Raid Devices : 5 Total Devices : 5 Preferred Minor : 2 The array was created like this. mdadm -v --create /dev/md2 \ --level=raid10 --layout=o2 --raid-devices=5 \ --chunk=64 --metadata=0.90 \ /dev/sdg2 /dev/sdf2 /dev/sde2 /dev/sdd2 /dev/sdc2 Each of the 5 individual drives have partitions like this.

The failure was a ugly and so individual drives fell out of the array a little at a time. While there are backups, we the are not really done as frequently as we really need. There is some data that I am trying to recover if I can. I got additional hardware and I was able to access the drives again. The drives appear to be fine, and I can get the array and filesystem active and mounted (using read-only mode). I am able to access some data on the filesystem and have been copying that off, but I am seeing lots of errors when I try to copy the most recent data. When I am trying to access that most recent data I am getting errors like below which makes me think that the array size discrepancy may be the problem.

• Pair programming tools that are not remote

  - by JonathanTech

  I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

• How can I listen to multiple Serial Ports asynchronously in C#

  - by Kamiel Wanrooij

  I have an application that listens to a piece of hardware on a USB to Serial converter. My application should monitor more than one serial port at the same time. I loop the serial ports I need to listen to, and create a thread for each port. In the thread I have my data handing routine. When I assign one port, it runs flawlessly. When I listen to the other one, it also works. When I open both ports however, the second port always throws an UnauthorizedAccessException when calling serialPort.Open(). It does not matter in what order I open the ports, the second one always fails. I listen to the ports using serialPort.ReadLine() in a while loop. Can .NET open more than one port at the same time? Can I listen to both? Or should I use another (thread safe?) way to access my serial port events?

• Android installation in a mobile

  - by Sundar

  Is it possible to install Android in a normal mobile phone? I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-). Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile? Any pointer/suggestion is appreciated. Thank you in advance.

• ActiveMQ Pure Master / Slave - Out of sync

  - by pico

  What i have : 1 master broker and 1 slave broker both in ActiveMQ 5.4.0 What i use : waitForSlave on master side and failover uri on slave side (in the master connector URI) What i want to do : I want to wait some delay (like 5 seconds) in case of a tiny network failures between master and slave before starting slave transpôrt connectors So i put this in slave config : <broker xmlns="http://activemq.apache.org/schema/core" brokerName="slave" dataDirectory="${activemq.base}/data" useJmx="true" persistent="true" populateJMSXUserID="true" masterConnectorURI="failover://(tcp://master:61616)?initialReconnectDelay=1000&amp;maxReconnectDelay=30000" shutdownOnMasterFailure="false" advisorySupport="false"> It seems to work but after a network hang between master and slave, the slave reconnect successfully and then the master logs a lot of : 2010-10-18 17:08:44,421 | ERROR | Slave Failed | org.apache.activemq.broker.ft.MasterBroker | ActiveMQ Task java.lang.IllegalStateException: Cannot lookup a connection that had not been registered: ID:master-1040-634226732611718750-0:0 at org.apache.activemq.broker.MapTransportConnectionStateRegister.lookupConnectionState(MapTransportConnectionStateRegister.java:93) at org.apache.activemq.broker.TransportConnection.lookupConnectionState(TransportConnection.java:1412) at org.apache.activemq.broker.TransportConnection.processRemoveConsumer(TransportConnection.java:561) at org.apache.activemq.command.RemoveInfo.visit(RemoveInfo.java:76) at org.apache.activemq.broker.TransportConnection.service(TransportConnection.java:309) at org.apache.activemq.broker.TransportConnection$1.onCommand(TransportConnection.java:185) at org.apache.activemq.transport.ResponseCorrelator.onCommand(ResponseCorrelator.java:116) at org.apache.activemq.transport.TransportFilter.onCommand(TransportFilter.java:69) at org.apache.activemq.transport.vm.VMTransport.iterate(VMTransport.java:218) at org.apache.activemq.thread.DedicatedTaskRunner.runTask(DedicatedTaskRunner.java:98) at org.apache.activemq.thread.DedicatedTaskRunner$1.run(DedicatedTaskRunner.java:36) On the slave side everything is fine.

• Server Security

  - by mahatmanich

  I want to run my own root server (directly accessible from the web without a hardware firewall) with debian lenny, apache2, php5, mysql, postfix MTA, sftp (based on ssh) and maybe dns server. What measures/software would you recomend, and why, to secure this server down and minimalize the attack vector? Webapplications aside ... This is what I have so far: iptables (for gen. packet filtering) fail2ban (brute force attack defense) ssh (chang default, port disable root access) modsecurity - is really clumsy and a pain (any alternative here?) ?Sudo why should I use it? what is the advantage to normal user handling thinking about greensql for mysql www.greensql.net is tripwire worth looking at? snort? What am I missing? What is hot and what is not? Best practices? I like "KISS" - Keep it simple secure, I know it would be nice! Thanks in advance ...

• tcp checksum and tcp offloading

  - by scatman

  i am using raw sockets to create my own socket. i need to set the tcp_checksum. i have tried a lot of references but all are not working (i am using wireshark for testing). could you help me please. by the way, i read somewhere that if you set tcp_checksum=0. then the hardware will calculate the checksum automatically for you. is this true? i tried it, but in wireshark the tcp_checksum gives a value of 0X000 and says tcp offload. i also read about tcp offloading, and didn't understand, is it only that wireshark is cannot check an offloaded tcp checksum, but there is a correct one??

• glTexImage2D behavior on iPhone and other OpenGL ES platforms

  - by spurserh

  Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. I suspect that the use of glTexImage2D with one or two frames of look-ahead, that is, using several textures so that the glTexImage2D call can be initiated a frame or two ahead, will allow for sufficient parallelism to play in real time if the system is capable of it at all. Is my assumption true that the driver will handle the actual data transfer to the hardware asynchronously after glTexImage2D returns, assuming I don't try to use the texture or call glFinish/glFlush? Is there a better way to do this with OpenGL ES? Thank you very much, Sean

• IIS6 Virtual Directory 500 Error on Remote Share

  - by David

  We have our servers at the server farm in a domain. Let's call it LIVE. Our developer computers live in a completely separate corporate domain, miles and miles away. Let's call it CORP. We have a large central storage unit (unix) that houses images and other media needed by many webservers in the server farm. The IIS application pools run as (let's say) LIVE\MediaUser and use those credentials to connect to a central storage share as a virtual directory, retrieve the images, and serve them as if they were local on each server. The problem is in development. On my development machine. I log in as CORP\MyName. My IIS 6 application pool runs as Network Service. I can't run it as a user from the LIVE domain because my machine isn't (and can not be) joined to that domain. I try to create a virtual directory, point it to the same network directory, click Connect As, uncheck the "Always use the authenticated user's credentials when validating access to the network directory" checkbox so that I can enter the login info, enter the credentails for LIVE\MediaUser, click OK, verify the password, etc. This doesn't work. I get "HTTP Error 500 - Internal server error" from IIS. The IIS log file reports sc-status = 500, sc-substatus = 16, and sc-win32-status = 1326. The documentation says this means "UNC authorization credentials are incorrect" and the Win32 status means "Logon failure: unknown user name or bad password." This would be all and good if it were anywhere close to accurate. I double- and trouble-checked it. Tried multiple known good logins. The IIS manager allows me to view the file tree in its window, it's only the browser that kicks me out. I even tried going to the virtual directory's Directory Security tab, and under Authentication and Access Control, I tried using the same LIVE domain username for the anonymous access credential. No luck. I'm not trying to run any ASP, ASP.NET, or other dynamic anything out of the virtual directory. I just want IIS to be able to load static images, css, and js files. If anyone has some bright ideas I would be most appreciative!

• VMWare-Mount not recognizing virtual disks

  - by user36175

  I have two disks as .vmdk files, and four as .vdi files. I can boot virtual machines on them with Sun xMV VirtualBox, and they work just fine. However, I want to mount them on my local computer so I can read some files off of them without starting a virtual machine. I downloaded the vmware-mount utility, but I get this error, even when mounting .vmdk files, which should be VMWare images... Unable to mount the virtual disk. The disk may be in use by a virtual machine, may not have enough volumes or mounted under another drive letter. If not, verify that the file is a valid virtual disk file. Thinking it's a problem with the utility, I downloaded the SDK and made my own simple program in C to try to mount a disk. It just initializes the API, connects to it, then attempts to open the disk. I get this error, once again claiming it is not a virtual disk: **LOG: DISKLIB-DSCPTR: descriptor above max size: I64u **LOG: DISKLIB-LINK : "f:\programming\VMs\windowstrash.vdi" : failed to open (The file specified is not a virtual disk). **LOG: DISKLIB-CHAIN : "f:\programming\VMs\windowstrash.vdi" : failed to open (The file specified is not a virtual disk). **LOG: DISKLIB-LIB : Failed to open 'f:\programming\VMs\windowstrash.vdi' with flags 0x1e (The file specified is not a virtual disk). ** FAILURE ** : The file specified is not a virtual disk The files are clearly virtual disks, though, since I can actually mount and use them with a virtual machine. I tried detaching them from any VMs and trying again, but I got the same results. Any ideas? Maybe the "descriptor above max size" is a hint? Some more info: the .vmdk disks were created on other computers. I just copied them to mine and created new VMs around them, but they work fine. All the .vdi files were created on my machine. Not sure if that affects anything. Update: WinMount can mount the file.. so the problem seems to be with vmware-mount.

• Installing fonts

  - by Lazar

  I have "white nights" trying to install Hebrew/Arabic fonts on my level 7 (API 2.1) aka Nexus emulator. I can't understand why Google guys will want to waist my skills do something helpful for the community using Hebrew/Arabic fonts. After rw mount/remount I can do it for level 3 devices, but for Nexus - nada! Why? What can be done? Real devices guys already broke this peace of hardware, but I am sitting and looking wide eyes open like a sheep. Please make me happy and give the chance to install the fonts. That's what must be done for some of us: We need system image saved on exit for tomorrow to continue the work Open emulator to work in peace cp command included with the SDK. Thanks for any help

• Authenticating Apache HTTPd against multiple LDAP servers with expired accounts

  - by Brian Bassett

  We're using mod_authnz_ldap and mod_authn_alias in Apache 2.2.9 (as shipped in Debian 5.0, 2.2.9-10+lenny7) to authenticate against multiple Active Directory domains for hosting a Subversion repository. Our current configuration is: # Turn up logging LogLevel debug # Define authentication providers <AuthnProviderAlias ldap alpha> AuthLDAPBindDN "CN=Subversion,OU=Service Accounts,O=Alpha" AuthLDAPBindPassword [[REDACTED]] AuthLDAPURL ldap://dc01.alpha:3268/?sAMAccountName?sub? </AuthnProviderAlias> <AuthnProviderAlias ldap beta> AuthLDAPBindDN "CN=LDAPAuth,OU=Service Accounts,O=Beta" AuthLDAPBindPassword [[REDACTED]] AuthLDAPURL ldap://ldap.beta:3268/?sAMAccountName?sub? </AuthnProviderAlias> # Subversion Repository <Location /svn> DAV svn SVNPath /opt/svn/repo AuthName "Subversion" AuthType Basic AuthBasicProvider alpha beta AuthzLDAPAuthoritative off AuthzSVNAccessFile /opt/svn/authz require valid-user </Location> We're encountering issues with users that have accounts in both Alpha and Beta, especially when their accounts in Alpha are expired (but still present; company policy is that the accounts live on for at a minimum of 1 year). For example, when the user x (which has en expired account in Alpha, and a valid account in Beta), the Apache error log reports the following: [Tue May 11 13:42:07 2010] [debug] mod_authnz_ldap.c(377): [client 10.1.1.104] [14817] auth_ldap authenticate: using URL ldap://dc01.alpha:3268/?sAMAccountName?sub?

• Floating point conversion from Fixed point algorithm

  - by Viks

  Hi, I have an application which is using 24 bit fixed point calculation.I am porting it to a hardware which does support floating point, so for speed optimization I need to convert all fixed point based calculation to floating point based calculation. For this code snippet, It is calculating mantissa for(i=0;i<8207;i++) { // Do n^8/7 calculation and store // it in mantissa and exponent, scaled to // fixed point precision. } So since this calculation, does convert an integer to mantissa and exponent scaled to fixed point precision(23 bit). When I tried converting it to float, by dividing the mantissa part by precision bits and subtracting the exponent part by precision bit, it really does' t work. Please help suggesting a better way of doing it.

• linear interpolation on 8bit microcontroller

  - by JB

  I need to do a linear interpolation over time between two values on an 8 bit PIC microcontroller (Specifically 16F627A but that shouldn't matter) using PIC assembly language. Although I'm looking for an algorithm here as much as actual code. I need to take an 8 bit starting value, an 8 bit ending value and a position between the two (Currently represented as an 8 bit number 0-255 where 0 means the output should be the starting value and 255 means it should be the final value but that can change if there is a better way to represent this) and calculate the interpolated value. Now PIC doesn't have a divide instruction so I could code up a general purpose divide routine and effectivly calculate (B-A)/(x/255)+A at each step but I feel there is probably a much better way to do this on a microcontroller than the way I'd do it on a PC in c++ Has anyone got any suggestions for implementing this efficiently on this hardware?

• External USB attached drive works in Windows XP but not in Windows 7. How to fix?

  - by irrational John

  Earlier this week I purchased this "N52300 EZQuest Pro" external hard drive enclosure from here. I can connect the enclosure using USB 2.0 and access the files in both NTFS partitions on the MBR partitioned drive when I use either Windows XP (SP3) or Mac OS X 10.6. So it works as expected in XP & Snow Leopard. However, the enclosure does not work in Windows 7 (Home Premium) either 64-bit or 32-bit or in Ubuntu 10.04 (kernel 2.6.32-23-generic). I'm thinking this must be a Windows 7 driver problem because the enclosure works in XP & Snow Leopard. I do know that no special drivers are required to use this enclosure. It is supported using the USB mass storage drivers included with XP and OS X. It should also work fine using the mass storage support in Windows 7, no? FWIW, I have also tried using 32-bit Windows 7 on both my desktop, a Gigabyte GA-965P-DS3 with a Pentium Dual-Core E6500 @ 2.93GHz, and on my early 2008 MacBook. I see the same failure in both cases that I see with 64-bit Windows 7. So it doesn't appear to be specific to one hardware platform. I'm hoping someone out there can help me either get the enclosure to work in Windows 7 or convince me that the enclosure hardware is bad and should be RMAed. At the moment though an RMA seems pointless since this appears to be a (Windows 7) device driver problem. I have tried to track down any updates to the mass storage drivers included with Windows 7 but have so far come up empty. Heck, I can't even figure out how to place a bug report with Microsoft since apparently the grace period for Windows 7 email support is only a few months. I came across a link to some USB troubleshooting steps in another question. I haven't had a chance to look over the suggestions on that site or try them yet. Maybe tomorrow if I have time ... ;-) I'll finish up with some more details about the problem. When I connect the enclosure using USB to Windows 7 at first it appears everything worked. Windows detects the drive and installs a driver for it. Looking in Device Manager there is an entry under the Hard Drives section with the title, Hitachi HDT721010SLA360 USB Device. When you open Windows Disk Management the first time after the enclosure has been attached the drive appears as "Not initialize" and I'm prompted to initialize it. This is bogus. After all, the drive worked fine in XP so I know it has already been initialized, partitioned, and formatted. So of course I never try to initialize it "again". (It's a 1 GB drive and I don't want to lose the data on it). Except for this first time, the drive never shows up in Disk Management again unless I uninstall the Hitachi HDT721010SLA360 USB Device entry under Hard Drives, unplug, and then replug the enclosure. If I do that then the process in the previous paragraph repeats. In Ubuntu the enclosure never shows up at all at the file system level. Below are an excerpt from kern.log and an excerpt from the result of lsusb -v after attaching the enclosure. It appears that Ubuntu at first recongnizes the enclosure and is attempting to attach it, but encounters errors which prevent it from doing so. Unfortunately, I don't know whether any of this info is useful or not. excerpt from kern.log [ 2684.240015] usb 1-2: new high speed USB device using ehci_hcd and address 22 [ 2684.393618] usb 1-2: configuration #1 chosen from 1 choice [ 2684.395399] scsi17 : SCSI emulation for USB Mass Storage devices [ 2684.395570] usb-storage: device found at 22 [ 2684.395572] usb-storage: waiting for device to settle before scanning [ 2689.390412] usb-storage: device scan complete [ 2689.390894] scsi 17:0:0:0: Direct-Access Hitachi HDT721010SLA360 ST6O PQ: 0 ANSI: 4 [ 2689.392237] sd 17:0:0:0: Attached scsi generic sg7 type 0 [ 2689.395269] sd 17:0:0:0: [sde] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) [ 2689.395632] sd 17:0:0:0: [sde] Write Protect is off [ 2689.395636] sd 17:0:0:0: [sde] Mode Sense: 11 00 00 00 [ 2689.395639] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412003] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412009] sde: sde1 sde2 [ 2689.455759] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.455765] sd 17:0:0:0: [sde] Attached SCSI disk [ 2692.620017] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2707.740014] usb 1-2: device descriptor read/64, error -110 [ 2722.970103] usb 1-2: device descriptor read/64, error -110 [ 2723.200027] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2738.320019] usb 1-2: device descriptor read/64, error -110 [ 2753.550024] usb 1-2: device descriptor read/64, error -110 [ 2753.780020] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2758.810147] usb 1-2: device descriptor read/8, error -110 [ 2763.940142] usb 1-2: device descriptor read/8, error -110 [ 2764.170014] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2769.200141] usb 1-2: device descriptor read/8, error -110 [ 2774.330137] usb 1-2: device descriptor read/8, error -110 [ 2774.440069] usb 1-2: USB disconnect, address 22 [ 2774.440503] sd 17:0:0:0: Device offlined -

When I use Firewire I can connect whether I'm using Windows 7 or Ubuntu 10.04. I even tried booting my Gigabyte desktop as an OS X 10.6.3 Hackintosh and it worked there as well. (Though if I recall correctly, it also worked when using USB 2.0 and booting OS X on the desktop. Certainly it works with USB 2.0 and my MacBook.) I believe the firmware on the device is at the latest level available, v1.07. I base this on the excerpt below from the OS X System Profiler which shows Firmware Revision: 0x107. Bottom line: It's nice that the enclosure is actually usable when I connect with Firewire.

• HP DAT72x6 autoloader

  - by ericmayo

  Hoping someone here has seen this similar issue and can offer soem advise... I have an HP DAT72x6 auto loader tape backup unit. The external kind, here is a link to an owner's manual I found of it. http://www.dectrader.com/docs/set2/emr_na-c00070400-1.pdf I purchased the unit used about 6 months ago. The unit stopped working after 3-4 back-ups, it's used one day a month to do a monthly backup of another system. Suffice it to say the unit gets very little usage. There is an amber light on the front of the unit called the OAR (Operator Attention Required). The manual states to call for service when this light comes on and stays on. I've tried a few things to resolve but none are working. I've tried power cycling, re-securing the SCSI cables at both ends. Unit was used so I didn't pay much ($500) and so I don't want to spend a lot to have it fixed; might as well buy something new one if fixing this is going to cost more than $100-$150 bucks. I'm curious to see if anyone here has been around these devices or possibly is an HP repair person that can give me some things to try to resolve. The manual states that a solid amber OAR light indicates a hardware failure. When I power cycle the unit I see one of two scenarios so far. The unit powers up, shows self test in the LCD, then LCD changes to show all possible images and the OAR light comes on. The unit powers up, LCD is completely blank, the green lights go through some sort of process of going on and off and later the amber OAR light comes on and stays on. If it's a simple misalignment issue, I may be able to fix myself but not knowing what could cause the OAR light to come on gives me no where to even start. Google around gave no help either. I hoping someone here has experience with this and can help or point me in the right direction. Also, I don't have the HP Diagnostic tools mentioned in many manuals. The unit is connected to a Linux box. The 3-4 backups I've done with it so far have had no issues. We run amanda backup. Before this incident the unit was backing up and reading tapes fine. Thanks for any help or suggestions.

• libvirt qemu/kvm migration problem

  - by Panda

  I am using kvm and libvirt on my Dell server. Now i am trying to migrate one virtual machine from a physical server to another. However, I failed everytime. In virsh on physicalServer1, I typed: virsh # migrate virtualmachine1 qemu+ssh://username@physicalServer2/system error: operation failed: migration to 'tcp:physicalServer2:49163' failed: migration failed Then I searched FAQ part on libvirt.org. It says: error: operation failed: migration to '...' failed: migration failed This is an error often encountered when trying to migrate with QEMU/KVM. This typically happens with plain migration, when the source VM cannot connect to the destination host. You will want to make sure your hosts are properly configured for migration (see the migration section of this FAQ) I managed to ssh physicalServer2 from a shell on virtualmachine1 so the above red part did not explain my failure. I also open ports on physicalServer2, iptables -L shows following information: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT tcp -- anywhere anywhere state NEW tcp dpts:49152:49215 Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer2: 2011-05-06 13:37:30.708: starting up 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-0.14 -enable-kvm -m 2048 -smp 1,sockets=1,cores=1,threads=1 -name openjudge-test -uuid a8c704bc-a4f9-90db-3e57-40e60b00aac1 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/virtualmachine1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=readline -rtc base=utc -boot c -drive file=/media/nfs/virtualmachine1.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 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=20,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:16:36:8a:22 :a0,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:2 -vga cirrus -incoming tcp:0.0.0.0:49163 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/0 2011-05-06 13:37:30.915: shutting down The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer1 is empty.

• Trailing dots in url result in empty 404 page on IIS

  - by Peter Hahndorf

  I have an ASP.NET site on IIS8, but IIS7.5 behaves exactly the same. When I enter a URL like: mysite.com/foo/bar.. I get the following error with a '500 Internal Server Error' status code: even though I have custom error pages set up for 500 and 404 and I don't see anything wrong with my custom error page. In my web.config system.web node I have the following: <customErrors mode="On"> <error statusCode="404" redirect="/404.aspx" /> </customErrors> If I remove that section, I get a 404.0 response back but the page itself is blank. In web.config system.webServer I have: <httpErrors errorMode="DetailedLocalOnly"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="404.html" responseMode="File" /> </httpErrors> But whether that is there or not, I get the same blank 404.0 page rather than my expected custom error page, or at least an internal IIS message. So first of all why is the asp.net handler picking up a request for '..' (also works with one or more trailing dots) If I remove the following handler from applicacationHost.config: <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" /> I get my expected custom 404 page, but of course removing that handler breaks routing in asp.net among other things. Looking at the failure trace I see: Windows Authentication is disabled for the site, so why is that module even in the request pipeline? For now my fix is to use the URL Rewrite module with the following rule: <rewrite> <rules> <rule name="Trailing Dots" stopProcessing="true"> <match url="\.+$" /> <action type="Rewrite" url="/404.html" appendQueryString="false" /> </rule> </rules> </rewrite> This works okay, but I wonder why IIS/ASP.NET behaves this way?

• Keyboard Simulation not working with Keyboard hook for modifier keys

  - by Eduardo Wada

  I have a piece of software that is being used to simulate a certain device on a touchscreen, this device already runs an application that receives keyboard input from the device. My software (reffered to as simulator) displays a virtual keyboard and runs the application. Thus, the simulator sends keys with input simulator: http://inputsimulator.codeplex.com/ And the applciation listens to keys with the following keyboard hook: https://svn.cyberduck.io/tags/release-4-1/source/ch/cyberduck/core/GlobalKeyboardHook.cs My problem is, what some keys from the device's hardware actually do is to sent a key combination (ex: left-alt + 1) to the application and a weird scenario is occurring: The application listens to normal keyboard inputs The simulator sends keys to other applications (ie: visual studio responds to the keys sent when debugging) The simulator can send single keys to the application (I can type) The simulator CANNOT send key combinations to the application (alt+1 is received as just 1 in the application) This started happenning when we imported the application's dll into the same process from the simulator. Could there be any reason why I can't simulate key combinations for a hook in the same process? Is there any easy fix for this?

• Adobe AIR: touch screen doesn't trigger mouse down event correctly

  - by Saariko

  i have designed a gaming kiosk app in as3 i am using it on a Sony vaio l pc (like hp's touchsmarts) in windows 7 the app doesn't need any multi-touch gestures (only single touch clicks and drags) so i am using mouse events everything is fine (including mouse click and move events) except that a single touch to the screen (with no move) doesn't fire a mouse down. it is fired only after a small move of the finger outside the app, on my desktop, i see that the small windows 7 cursor jumps immediately to where a finger is placed, meaning this issue isn't a hardware or a windows problem but rather how internally the flash app receives "translated" touch-to-mouse events from the os. for example, in a windows Solitaire game, a simple touch to the screen immediately highlights the touched card. in my app, a button will change to the down state only if i touch it and also move my finger slightly (click events - down and up - are triggered fine) shouldn't the MOUSE_DOWN event trigger exactly like how a TOUCH_BEGIN would in the new touchevent class? any ideas?

• AudioQueue recording as float

  - by niklassaers

  Hi guys, I would like to have the result from my recording as a float in the range [0.0, 1.0], alternatively [-1.0, 1.0] because of a bit of math I want to do on it. When I set my recordingformat to be in float, like this: mRecordFormat.mFormatFlags = kLinearPCMFormatFlagIsFloat; I get: Error: AudioQueueNewInput failed ('fmt?') Does this mean the hardware doesn't support recording to floats? If not, how do I set it to record in floats? If so, are there any processor-friendly ways I can convert a signed integer array to a float array? Cheers Nik

• SSRS 2005 - Usability analysis - Is SSRS a good option for this scenario?

  - by Sach

  How practical is it to consider SSRS 2005 or SSRS 2008 as a reporting solution for a report that has to show reports with millions of records (records vary from 3 to 10 million)? Is there any threshold on the size of report in SSRS? How do I know that for a huge report, wheather SSRS will consume the whole memory and start paging the operations to disk or it will give a memory leak error? Even if I keep on increasing the memory how can I be sure that certain memory will be sufficient for such huge reports for the report server? All the above questions are haunting me because I have a dedicated report server with a decent hardware and OS configuration (8 processors, 8GB RAM, 64 bit OS and 64 bit SQL Server 2005). Still my report with around 2 million records is taking more than 6 minutes and going from one page to another takes 3 minutes!!! My datasource is on separate server and when I execute only the stored proc there, it returns the results in less than 2 minutes.

• Nginx Retry of Requests ( Nginx - Haproxy Combination )

  - by vaibhav

  I wanted to ask about Nginx Retry of Requests. I have a Nginx running at the backend which then sends the requests to HaProxy which then passes it on the web server and the request is processed. I am reloading my Haproxy config dynamically to provide elasticity. The problem is that the requests are dropped when I reload Haproxy. So I wanted to have a solution where I can just retry that from Nginx. I looked through the proxy_connect_timeout, proxy_next_upstream in http module and max_fails and fail_timeout in server module. I initially only had 1 server in the upstream connections so I just that up twice now and less requests are getting dropped ( only when ) have say the same server twice in upstream , if I have same server 3-4 times drops increase ). So , firstly I wanted to now , that when a request is not able to establish connection from Nginx to Haproxy so while reloading it seems that conneciton is seen as error and straightway the request is dropped . So how can I either specify the time after the failure I want to retry the request from Nginx to upstream or the time before which Nginx treats it as failed request. ( I have tried increaing proxy_connect_timeout - didn't help , mail_retires , fail_timeout and also putting the same upstream server twice ( that gave the best results so far ) Nginx Conf File upstream gae_sleep { server 128.111.55.219:10000; } server { listen 8080; server_name 128.111.55.219; root /var/apps/sleep/app; # Uncomment these lines to enable logging, and comment out the following two #access_log /var/log/nginx/sleep.access.log upstream; error_log /var/log/nginx/sleep.error.log; access_log off; #error_log /dev/null crit; rewrite_log off; error_page 404 = /404.html; set $cache_dir /var/apps/sleep/cache; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://gae_sleep; client_max_body_size 2G; proxy_connect_timeout 30; client_body_timeout 30; proxy_read_timeout 30; } location /404.html { root /var/apps/sleep; } location /reserved-channel-appscale-path { proxy_buffering off; tcp_nodelay on; keepalive_timeout 55; proxy_pass http://128.111.55.219:5280/http-bind; } }

• iPad UI clipped in simulator

  - by raj.tiwari

  My views created for iPad form factor look fine in Interface Builder. However, when I debug my app in iPhone Simulator 3.2 (with Hardware - Device set to iPad), I see the UI clipped and about half size. There is a 2x button at the bottom which lets me zoom in. But this just shows the same clipped UI in double size. This is really weird since I have created the XIB for iPad form factor and it is supposed to fit iPad completely. Any ideas what I might be doing wrong? I am using iPhone SDK 3.2 downloaded on 4/30/2010. Thanks. -Raj
