need help with automating a CMD java tool whcih qurries alexa AWS using batch

- by Eli.C

Hi everyone, I need to get all available info on 600 URLs from "Alexa Web Information Service", I downloaded the java tool and I'm able to run a single query each time with a single switch/Response Group. I would like to ask how to write a batch file that would automate the process ? the java tool runs from the CMD with the following: C:java UrlInfo (key1) (key2) (URL) (Response Group) UrlInfo - constant key1 - constant key2 -constant URL - variable (I guess I need to use the "(" sign to read from a file) Response Group - variable - (14 total, and I need to run each Response Group on each of the URLs once ) the app returns data in clear text formatted as XML after each query, here is an example: C:java UrlInfo (key1) (key2) www.url.com Rank Response: (?xml version="1.0"?) (aws:UrlInfoResponse xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/") (aws:Response xmlns:aws="http://awis.amazonaws.com/doc/2005-07-11") (aws:OperationRequest) (aws:RequestId)ec2b6-e8ae-b392(/aws:RequestId) (/aws:OperationRequest) (aws:UrlInfoResult) (aws:Alexa) (aws:TrafficData) (aws:DataUrl type="canonical")url.com/(/aws:DataUrl) (aws:Rank)472906(/aws:Rank) (/aws:TrafficData) (/aws:Alexa) (/aws:UrlInfoResult) (aws:ResponseStatus xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/") (aws:StatusCode)Success(/aws:StatusCode) (/aws:ResponseStatus) (/aws:Response) (/aws:UrlInfoResponse) Any help would be really appreciated Thanks and regards Eli.C

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

- by John Stumbles

Debian 6 on HP proliant (2 CPU) with raid (2*1.5T RAID1 + 2*2T RAID1 joined RAID0 to make 3.5T) running mainly nfs & imapd (plus samba for windows share & local www for previewing web pages); with local ubuntu desktop client mounting $HOME, laptops accessing imap & odd files (e.g. videos) via nfs/smb; boxes connected 100baseT or wifi via home router/switch uname -a Linux prole 2.6.32-5-686 #1 SMP Wed Jan 11 12:29:30 UTC 2012 i686 GNU/Linux Setup has been working for months but prone to intermittently going very slow (user experience on desktop mounting $HOME from server, or laptop playing videos) and now consistently so bad I've had to delve into it to try to find what's wrong(!) Server seems OK at low load e.g. (laptop) client (with $HOME on local disk) connecting to server's imapd and nfs mounting RAID to access 1 file: top shows load ~ 0.1 or less, 0 wait but when (desktop) client mounts $HOME and starts user KDE session (all accessing server) then top shows e.g. top - 13:41:17 up 3:43, 3 users, load average: 9.29, 9.55, 8.27 Tasks: 158 total, 1 running, 157 sleeping, 0 stopped, 0 zombie Cpu(s): 0.4%us, 0.4%sy, 0.0%ni, 49.0%id, 49.7%wa, 0.0%hi, 0.5%si, 0.0%st Mem: 903856k total, 851784k used, 52072k free, 171152k buffers Swap: 0k total, 0k used, 0k free, 476896k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3935 root 20 0 2456 1088 784 R 2 0.1 0:00.02 top 1 root 20 0 2028 680 584 S 0 0.1 0:01.14 init 2 root 20 0 0 0 0 S 0 0.0 0:00.00 kthreadd 3 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/0 4 root 20 0 0 0 0 S 0 0.0 0:00.12 ksoftirqd/0 5 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/0 6 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/1 7 root 20 0 0 0 0 S 0 0.0 0:00.16 ksoftirqd/1 8 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/1 9 root 20 0 0 0 0 S 0 0.0 0:00.42 events/0 10 root 20 0 0 0 0 S 0 0.0 0:02.26 events/1 11 root 20 0 0 0 0 S 0 0.0 0:00.00 cpuset 12 root 20 0 0 0 0 S 0 0.0 0:00.00 khelper 13 root 20 0 0 0 0 S 0 0.0 0:00.00 netns 14 root 20 0 0 0 0 S 0 0.0 0:00.00 async/mgr 15 root 20 0 0 0 0 S 0 0.0 0:00.00 pm 16 root 20 0 0 0 0 S 0 0.0 0:00.02 sync_supers 17 root 20 0 0 0 0 S 0 0.0 0:00.02 bdi-default 18 root 20 0 0 0 0 S 0 0.0 0:00.00 kintegrityd/0 19 root 20 0 0 0 0 S 0 0.0 0:00.00 kintegrityd/1 20 root 20 0 0 0 0 S 0 0.0 0:00.02 kblockd/0 21 root 20 0 0 0 0 S 0 0.0 0:00.08 kblockd/1 22 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpid 23 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpi_notify 24 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpi_hotplug 25 root 20 0 0 0 0 S 0 0.0 0:00.00 kseriod 28 root 20 0 0 0 0 S 0 0.0 0:04.19 kondemand/0 29 root 20 0 0 0 0 S 0 0.0 0:02.93 kondemand/1 30 root 20 0 0 0 0 S 0 0.0 0:00.00 khungtaskd 31 root 20 0 0 0 0 S 0 0.0 0:00.18 kswapd0 32 root 25 5 0 0 0 S 0 0.0 0:00.00 ksmd 33 root 20 0 0 0 0 S 0 0.0 0:00.00 aio/0 34 root 20 0 0 0 0 S 0 0.0 0:00.00 aio/1 35 root 20 0 0 0 0 S 0 0.0 0:00.00 crypto/0 36 root 20 0 0 0 0 S 0 0.0 0:00.00 crypto/1 203 root 20 0 0 0 0 S 0 0.0 0:00.00 ksuspend_usbd 204 root 20 0 0 0 0 S 0 0.0 0:00.00 khubd 205 root 20 0 0 0 0 S 0 0.0 0:00.00 ata/0 206 root 20 0 0 0 0 S 0 0.0 0:00.00 ata/1 207 root 20 0 0 0 0 S 0 0.0 0:00.14 ata_aux 208 root 20 0 0 0 0 S 0 0.0 0:00.01 scsi_eh_0 dmesg suggests there's a disk problem: ..............

(I'm guessing I could buy a larger drive if the price is right: I'm thinking that one day I'll need to grow the size of the array and that would be one less drive to replace with a larger one) then use mdadm to fail out the existing sdc, remove it and fit the new drive fdisk the new drive with the same size partition for the array as the old one had use mdadm to add the new drive into the array that sound OK?

Setting up Apache 2.2 + FastCGI + SuExec + PHP-FPM on Centos 6

- by mr1031011

I'm trying to follow this very detailed instruction here, I simply changed from www-data user to apache user, and is using /var/www/hosts/sitename/public_html instead of /home/user/public_html However, I spent the whole day trying to figure out why the php file content is displayed without being parsed correctly. I just cant's seem to figure this out. Below is my current config: /etc/httpd/conf.d/fastcgi.conf User apache Group apache LoadModule fastcgi_module modules/mod_fastcgi.so # dir for IPC socket files FastCgiIpcDir /var/run/mod_fastcgi # wrap all fastcgi script calls in suexec FastCgiWrapper On # global FastCgiConfig can be overridden by FastCgiServer options in vhost config FastCgiConfig -idle-timeout 20 -maxClassProcesses 1 # sample PHP config # see /usr/share/doc/mod_fastcgi-2.4.6 for php-wrapper script # don't forget to disable mod_php in /etc/httpd/conf.d/php.conf! # # to enable privilege separation, add a "SuexecUserGroup" directive # and chown the php-wrapper script and parent directory accordingly # see also http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/ # FastCgiServer /var/www/www-data/php5-fcgi #AddType application/x-httpd-php .php AddHandler php-fcgi .php Action php-fcgi /fcgi-bin/php5-fcgi Alias /fcgi-bin/ /var/www/www-data/ #FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /tmp/php5-fpm.sock -pass-header Authorization #DirectoryIndex index.php # <Location /fcgi-bin/> # Order Deny,Allow # Deny from All # Allow from env=REDIRECT_STATUS SetHandler fcgid-script Options +ExecCGI </Location> /etc/httpd/conf.d/vhost.conf <VirtualHost> DirectoryIndex index.php index.html index.shtml index.cgi SuexecUserGroup www.mysite.com mygroup Alias /fcgi-bin/ /var/www/www-data/www.mysite.com/ DocumentRoot /var/www/hosts/mysite.com/w/w/w/www/ <Directory /var/www/hosts/mysite.com/w/w/w/www/> Options -Indexes FollowSymLinks AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> PS: 1. Also, with PHP5.5, do I even need FPM or is it already included? 2. I'm using mod_fastcgi, not sure if this is the problem and it I should switch to mod_fcgid? There seems to be conflicting records on the internet considering which one is better. I have many virtual hosts running on the machine and hope to be able to provide each user with their own opcache

BES Express - configure MDS to push messages from 3rd party web application

- by Max Gontar

Hi! I have developed IIS web service to send PAP messages using Blackberry Push API over MDS. And there is an application installed on device, configured to receive push messages on appropriate port. Everything works well on MDS simulator. But it's not working well in real environment: I have installed BES Express and register several devices. I can browse MDS url with appropriate port, so url is correct. Also port enabled for reliable pushes is used in push message and in device application. Here is MDS simulator log: <2011-01-12 14:00:03.456 EET>:[272]:<MDS-CS_MDS>:<DEBUG>:<LAYER = SCM, EVENT = PapServlet: request from 0:0:0:0:0:0:0:1 564 bytes...> <2011-01-12 14:00:03.476

Windows 2012 Server: Enable .NET 3.5

- by Meengla

I have a Windows 2012 Server which needs .NET 3.5 installed. For background info/solutions, please see this: http://sqlblog.com/blogs/sergio_govoni/archive/2013/07/13/how-to-install-netfx3-on-windows-server-2012-required-by-sql-server-2012.aspx I have tried this but it doesn't work for me. Here is what I am trying: Using a Windows 2012 ISO file, 'mount' on the 2012 Server as 'D' drive and then tried both GUI and Command prompt. In case of GUI, I specified the 'alternate source' path to the D drive's 'source/sxs folder but that failed without giving enough info. In case of the command prompt, here is what's happening: dism /online /enable-feature /featurename:NetFx3 /source:d:\sources\sxs I get error: Installed but Parent feature not enabled. So I tried another approached: dism /online /enable-feature /featurename:NetFx3 /all /source:d:\sources\sxs the above command, per http://blogs.technet.com/b/askcore/archive/2012/05/14/windows-8-and-net-framework-3-5.aspx is supposed to enable parent elements; but running this I get error like 'source not found'. Is there some error in my second command? What else I could do? This is Windows 2012 Server Standard edition. Thanks!

About Load average in htop, how to decide if it's still doing ok?

- by Joe Huang

I use 'htop' to monitor my web server. It's recently quite loaded and the Load average is showing something like this: Load average: 3.10 2.56 1.63 I searched the web about these numbers and I found an article about it: http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages In the article, it says if I have 2 CPUs, 2.0 means 100% CPU utilization. And my VPS has two CPUs, so what does 3.1 mean? How could it exceed 100% CPU utilization? And from these numbers, does it mean I should be wary about the loading now? But the performance seems totally fine, and this is a managed VPS, the hosting company has not notified me any warning about it. During day time, Load average always show these high numbers... here is another snapshot while writing. Load average: 3.03 2.77 1.97 Load average: 0.41 1.29 1.60 <---- 5 more minutes later So I am wondering how much room left for this site to grow in current configurations? What kind of proactive actions I should take in advance? I don't want to wait until the server bursts. Thanks.

TSQL Conditionally Select Specific Value

- by Dzejms

This is a follow-up to #1644748 where I successfully answered my own question, but Quassnoi helped me to realize that it was the wrong question. He gave me a solution that worked for my sample data, but I couldn't plug it back into the parent stored procedure because I fail at SQL 2005 syntax. So here is an attempt to paint the broader picture and ask what I actually need. This is part of a stored procedure that returns a list of items in a bug tracking application I've inherited. There are are over 100 fields and 26 joins so I'm pulling out only the mostly relevant bits. SELECT tickets.ticketid, tickets.tickettype, tickets_tickettype_lu.tickettypedesc, tickets.stage, tickets.position, tickets.sponsor, tickets.dev, tickets.qa, DATEDIFF(DAY, ticket_history_assignment.savedate, GETDATE()) as 'daysinqueue' FROM dbo.tickets WITH (NOLOCK) LEFT OUTER JOIN dbo.tickets_tickettype_lu WITH (NOLOCK) ON tickets.tickettype = tickets_tickettype_lu.tickettypeid LEFT OUTER JOIN dbo.tickets_history_assignment WITH (NOLOCK) ON tickets_history_assignment.ticketid = tickets.ticketid AND tickets_history_assignment.historyid = ( SELECT MAX(historyid) FROM dbo.tickets_history_assignment WITH (NOLOCK) WHERE tickets_history_assignment.ticketid = tickets.ticketid GROUP BY tickets_history_assignment.ticketid ) WHERE tickets.sponsor = @sponsor The area of interest is the daysinqueue subquery mess. The tickets_history_assignment table looks roughly as follows declare @tickets_history_assignment table ( historyid int, ticketid int, sponsor int, dev int, qa int, savedate datetime ) insert into @tickets_history_assignment values (1521402, 92774,20,14, 20, '2009-10-27 09:17:59.527') insert into @tickets_history_assignment values (1521399, 92774,20,14, 42, '2009-08-31 12:07:52.917') insert into @tickets_history_assignment values (1521311, 92774,100,14, 42, '2008-12-08 16:15:49.887') insert into @tickets_history_assignment values (1521336, 92774,100,14, 42, '2009-01-16 14:27:43.577') Whenever a ticket is saved, the current values for sponsor, dev and qa are stored in the tickets_history_assignment table with the ticketid and a timestamp. So it is possible for someone to change the value for qa, but leave sponsor alone. What I want to know, based on all of these conditions, is the historyid of the record in the tickets_history_assignment table where the sponsor value was last changed so that I can calculate the value for daysinqueue. If a record is inserted into the history table, and only the qa value has changed, I don't want that record. So simply relying on MAX(historyid) won't work for me. Quassnoi came up with the following which seemed to work with my sample data, but I can't plug it into the larger query, SQL Manager bitches about the WITH statement. ;WITH rows AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY ticketid ORDER BY savedate DESC) AS rn FROM @Table ) SELECT rl.sponsor, ro.savedate FROM rows rl CROSS APPLY ( SELECT TOP 1 rc.savedate FROM rows rc JOIN rows rn ON rn.ticketid = rc.ticketid AND rn.rn = rc.rn + 1 AND rn.sponsor <> rc.sponsor WHERE rc.ticketid = rl.ticketid ORDER BY rc.rn ) ro WHERE rl.rn = 1 I played with it yesterday afternoon and got nowhere because I don't fundamentally understand what is going on here and how it should fit into the larger context. So, any takers? UPDATE Ok, here's the whole thing. I've been switching some of the table and column names in an attempt to simplify things so here's the full unedited mess. snip - old bad code Here are the errors: Msg 102, Level 15, State 1, Procedure usp_GetProjectRecordsByAssignment, Line 159 Incorrect syntax near ';'. Msg 102, Level 15, State 1, Procedure usp_GetProjectRecordsByAssignment, Line 179 Incorrect syntax near ')'. Line numbers are of course not correct but refer to ;WITH rows AS And the ')' char after the WHERE rl.rn = 1 ) Respectively Is there a tag for extra super long question?

Amazon VPC NAT not working

- by rpkelly

I'm trying to create a NAT instance for my VPC to allow instances on private subnets connect to the internet (most importantly, S3). I tried following the instructions here: http://docs.amazonwebservices.com/AmazonVPC/2011-07-15/UserGuide/index.html?VPC_NAT_Instance.html . Unfortunately, the instances in the private subnet (call it 10.10.2.0/24) cannot reach the internet. I have done the following: Create a NAT instance (Amazon's ami-vpc-nat-1.0.0-beta.i386-ebs (ami-d8699bb1)) in public subnet (call it 10.10.1.0/24). Changed "Source / Dest Check" to disabled. Created a new entry in the default routing table (which is used by 10.10.2.0/24) and had it point to the ID of the newly created instance. Associated an Elastic IP address with the NAT instance. Allowed all outbound traffic on the security group of the NAT instance. Ensured that all traffic could pass between the two subnets. I've tried also doing this with an existing instance using iptables, but had no luck. And I have verified that sys.net.ipv4.ip_forward is 1, just in case anyone was wondering. And I still have no internet connectivity from the instances on 10.10.2.0/24. Does anyone have any suggestions?

Exchange 2010 Recovery: Mailbox not found using Restore-Mailbox

- by user146665

Exchange 2010 SP1 Update Rollup 5 server information store database was restored to a Recovery Database using EMC Networker successfully. The Recovery Database is in a mounted state with mailboxes listed within in it. However, when restoring the mailbox content using the following command: Restore-Mailbox –Identity MYMAILBOX –RecoveryDatabase MYRECOVERYDB –RecoveryMailbox LOSTMAILBOX –TargetFolder FOLDERFORLOSTMAILBOX Returns the following error: Mailbox "LOSTMAILBOX" doesn't exist on database "MYRECOVERYDB". + CategoryInfo : NotSpecified: (0:Int32) [Restore-Mailbox], ManagementObjectNotFoundException + FullyQualifiedErrorId : 66265C53,Microsoft.Exchange.Management.RecipientTasks.RestoreMailbox Note: I've used the correct alias name for the mailbox name; i've also tried combinations such as first name, or last name or both and so forth. Issuing a Get-MailboxStatistics -Database MYRECOVERYDB to see if the mailbox is there and it is as shown below: DisplayName ItemCount StorageLimitStatus LOSTMAILBOX 39495 MailboxDisabled Note: The StorageLimitStatus shows a strange output of MaibloxDisabled. Perhaps this may be the culprit. Going by the article's documentation I cannot complete the restore of the mailbox as I'm stuck at the restore-mailbox error that it cannot be found. Please advise & Thank you! Source of article: http://www.testlabs.se/blog/2012/07/05/exchange-2010-restore-to-recovery-database-using-emc-networker/

NullPointerException, Collections not storing data?

- by Elliott

Hi there, I posted this question earlier but not with the code in its entirety. The coe below also calls to other classes Background and Hydro which I have included at the bottom. I have a Nullpointerexception at the line indicate by asterisks. Which would suggest to me that the Collections are not storing data properly. Although when I check their size they seem correct.

How could Load average numbers from 'htop' exceed 100% CPU utlization?

- by Joe Huang

I use 'htop' to monitor my web server. It's recently quite loaded and the Load average is showing something like this: Load average: 3.10 2.56 1.63 I searched the web about these numbers and I found an article about it: http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages In the article, it says if I have 2 CPUs, 2.0 means 100% CPU utilization. And my VPS has two CPUs, so what does 3.1 mean? How could it exceed 100% CPU utilization? And from these numbers, does it mean I should be wary about the loading now? But the performance seems totally fine, and this is a managed VPS, the hosting company has not notified me any warning about it. During day time, Load average always show these high numbers... here is another snapshot while writing. Load average: 3.03 2.77 1.97 Load average: 0.41 1.29 1.60 <---- 5 more minutes later So I am wondering how much room left for this site to grow in current configurations? What kind of proactive actions I should take in advance? I don't want to wait until the server bursts. Thanks.

Limit copssh users to home directory Windows 7

- by Siriss

Hello all- I have found these two sites below: CopSSH SFTP -- limit users access to their home directory only and http://blogs.windowsnetworking.com/wnadmin/2006/11/07/copssh-restricting-users-access/ as well as the Copssh website, but upon completion they do not seem to work. I have copssh installed and I have a separate Windows account "sftpuser" created that is used to connect. The connection works just fine, but I want to limit that user to just their home directory and sub folders. I have 3 hard drives, the C:, a W: and an S: and I want the FTP account to only be able to access the W: drive and its contents (the root of the W: drive is the FTP home directory). Right now "sftpuser" can access all folders, including jump drives to C:, and S:. The linked tutorials do not seem to work, because it seems when I create a group "ftpusersgroup" and add "sftpuser" to the group, and then deny "ftpusersgroup" access to the C: drive, the service breaks and I can no longer login. I have undone everything and am ready to start fresh. Does anyone know how to do this, or is there a better tutorial that someone has or has found? I hope this makes sense. Thank you very much for any help!

Has anyone managed to build php5-xapian on Ubuntu 12.04?

- by jetboy

As Xapian's been dropped from the Ubuntu repositories, I'm attempting to build my own .deb from the instructions here: http://article.gmane.org/gmane.comp.search.xapian.general/8855 http://beeznest.wordpress.com/2011/07/06/howto-build-your-own-binaries-of-php-xapian-bindings-for-debian/ I can only get things to progress beyond the first few seconds by leaving out 'rm debian/control', but if I do, it looks as if the Python and Ruby bindings are building and passing their versions of smoketest correctly. However, the PHP part of the build is failing with this error: /home/charlie/xapian-bindings-1.2.8/php/smoketest.php:38: include(xapian.php): failed to open stream: No such file or directory FAIL: smoketest.php There's a xapian.php file in /home/charlie/xapian-bindings-1.2.8/php/php5/ but if I copy it to /home/charlie/xapian-bindings-1.2.8/php/ or change the path to it in smoketest.php, the build fails right near the start with: dpkg-source: error: aborting due to unexpected upstream changes Unfortunately I'm out of my comfort zone building from source. Anyone got any ideas? Edit post James' answer: Builds fine if I follow instructions exactly. I built it on a test VM initially, but that didn't build the PHP package as PHP itself wasn't installed. Obvious gotcha, but worth mentioning. Installing generated the following error: Setting up php5-xapian (1.2.8-1) ... Processing triggers for libapache2-mod-php5 ... dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/libapache2-mod-php5.postinst): Permission denied ssion denied dpkg: error processing libapache2-mod-php5 (--install): subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: libapache2-mod-php5 It's only a script for restarting Apache. Stopping Apache before running sudo dpkg -i php5-xapian_*.deb prevents the error. Xapian now shows up in phpinfo(). Job done. Thanks.

Ubuntu 13.10 - How to disable LVM and cryptsetup? cryptsetup: evms_activate is not available

- by NeverEndingQueue

I am trying to remove whole drive encryption from my Ubuntu installation. I've run Ubuntu from Live CD, mounted crypt partition and copied it to another partition /dev/sda3. sudo cryptsetup luksOpen /dev/sda5 crypt1 sudo dd if=/dev/ubuntu-vg/root of=/dev/sda3 bs=1M After that I've run boot-repair: https://help.ubuntu.com/community/Boot-Repair Added entry to /etc/fstab: UUID=<uuid> / ext4 errors=remount-ro 0 1 Of course I've replaced with blkid result of my /dev/sda3. I've also deleted overlayfs and tmpfs lines from /etc/fstab. (I've just compared it to content of /etc/fstab in non-encrypted Ubuntu installation and could not find overlayfs and tmpfs). I've chrooted from LiveCD into my system and rebuilt initramfs: http://blog.leenix.co.uk/2012/07/evmsactivate-is-not-available-on-boot.html I've also removed cryptsetup using apt-get remove. Basically I can easily mount my system partition from Live CD (without setting up the encryption and LVM stuff), but can not boot from it. Instead I see: cryptsetup: evms_activate is not available When I've chosen the Recovery mode I've seen this: Begin: Mounting root file system ... Begin: Running /script/local-top ... Reading all physical volumes. This may take a while ... No volume groups found cryptsetup: evms_activate is not available Begin: Waiting for encrytpted source device ... My /etc/crypttab is empty. I am pretty sure that system tries to find encrypted partition, search for LVMs etc. Do you have ideas what could be the problem or how can I fix it? Thanks

Need help displaying a table dynamically based on a drop down date selection

- by Gideon

I am designing a job rota planner for a company and need help displaying a dynamic table containing the staff details. I have the following tables in MySQL database: Staff, Event, and Job. The staff table holds staff details (staffed, name, address...etc), the Event table (eventide, eventName, Fromdate, Todate...etc) and the Job table holds (Jobid, Jobdate, Eventid(fk), Staffid (fk)). I need to dynamically display the available staff list from the staff table when the user selects the event and the date (3 drop downs: date, month, and year) from a PHP form. I need to display staff members that have not been assigned work on the selected date by checking the Jobdate in the Job table. I have been at this for all day and can't get around it. I am still learning PHP and would surely appreciate any help I can get. My current code displays all staff members when an event is selected: //Create the day pull-down menu. $days = range (1, 31); echo "<Select Name=day Value=''><Option>Day</option>"; foreach ($days as $value) { echo '<option value="'.$value.'">'.$value.'</option>\n'; } echo "</Select>"; echo "</td><td>"; //Create the month pull-down menu echo "<Select Name=month Value=''><Option>Month</option>"; echo "<option value='01'>Jan</option>"; echo "<option value='02'>Feb</option>"; echo "<option value='03'>Mar</option>"; echo "<option value='04'>Apr</option>"; echo "<option value='05'>May</option>"; echo "<option value='06'>Jun</option>"; echo "<option value='07'>Jul</option>"; echo "<option value='08'>Aug</option>"; echo "<option value='09'>Sep</option>"; echo "<option value='10'>Oct</option>"; echo "<option value='11'>Nov</option>"; echo "<option value='12'>Dec</option>"; echo "</select>"; echo "</td><td>"; //Create the year pull-down menu $currentYear = date ("Y"); $years = range ($currentYear, 2020); echo "<Select Name=year Value=''><Option>Year</option>"; foreach ($years as $value) { echo '<option value="'.$value.'">'.$value.'</option>\n'; } echo "</Select>"; echo "</td></tr></table>"; echo "</td><td>"; //echo "<img src='../ETMSimages/etms_staff.png'</img></td><td>"; //construct the available staff list $staffsql = "SELECT StaffId, LastName, FirstName FROM Staff order by StaffId"; $staffResult = mysql_query($staffsql); if ($staffResult){ echo "<p><table cellspacing='1' cellpadding='3'>"; echo "<th colspan=6>List of Available Staff</th>"; echo "</tr><tr><th> Select</th><th>Id</th><th></th><th>Last Name </th><th></th><th>First Name </th></tr>"; while ($staffarray = mysql_fetch_array($staffResult)) { echo "<tr onMouseOver= this.bgColor = 'red' onMouseOut =this.bgColor = 'white' bgcolor= '#FFFFFF'> <td align=center><input type='checkbox' name='selectbox[]' id='selectbox[]' value=".$staffarray['StaffId']."> </td><td align=left>".$staffarray['StaffId']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['LastName']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['FirstName']." </td></tr>"; } echo "</table>"; } else { echo "<br> The Staff list can not be displayed!"; } echo "</td></tr>"; echo "<tr><td></td>"; echo "<td align=center><input type='submit' name='Submit' value='Assign Staff'>&nbsp&nbsp"; echo "<input type='reset' value='Start Over'>"; echo "</td></tr>"; echo "</table>";

I am using Agility HTML pack. this.htmlDoc = new HtmlAgilityPack.HtmlDocument(); this.htmlDoc.OptionCheckSyntax = true; this.htmlDoc.OptionFixNestedTags = true; this.htmlDoc.OptionAutoCloseOnEnd = true; this.htmlDoc.OptionOutputAsXml = true; // is this necessary ?? this.htmlDoc.OptionDefaultStreamEncoding = System.Text.Encoding.Default; I had a lot of trouble with getting those values out. I started with: var query = from html in doc.DocumentNode.SelectNodes("//div[@class='graf_table']").Cast<HtmlNode>() from table in html.SelectNodes("//table").Cast<HtmlNode>() from row in table.SelectNodes("tr").Cast<HtmlNode>() from cell in row.SelectNodes("th|td").Cast<HtmlNode>() select new { Table = table.Id, CellText = cell.InnerHtml }; but could not figure out a way to select only values where table header is DATUM and Maloprodajna cena[EUR/L]. Is it possible to do that with where clause? Then I ended with those two queries: var date = (from d in htmlDoc.DocumentNode.SelectNodes("//div[@class='graf_table']//table//tr[1]/td") select DateTime.Parse(d.InnerText)).ToArray(); var price = (from p in htmlDoc.DocumentNode.SelectNodes("//div[@class='graf_table']//table//tr[2]/td") select double.Parse(p.InnerText)).ToArray(); Is it possible to combine those two queries? And how would I convert that to lambda expression? I just started to learn those things and I would like to know how it is done so that in the future I would not have those question. O, one more question ... does anybody know any graph control, cause I have to show those values in graph. I started with Microsoft Chart Controls, but I am having trouble with setting it. So if anyone has any experience with it I would like to know how to set it, so that x axle will show all values not every second ... example: if I have: 10.03.2009, 24.03.2009, 07.04.2009, 21.04.2009, 05.05.2009, 06.05.2009 it show only: 10.03.2009, 07.04.2009, 05.05.2009, ect. I bind data to graph like that: chart1.Series["Series1"].Points.DataBindXY(date, price); I lot of questions for my fist post ... hehe, hope that I was not indistinct or something. Thank's for any reply!

Server on blacklist

- by Cudos

I have a Debian Wheezy server with several websites with separate domains. Some of these websites uses Wordpress and in turn uses PHP's mail function to send mail. I installed "sendmail" to be able for the server to send mail from PHP. We use Google Apps for our customers, so no need to setup a regular mail server. Now the server is blacklisted at www.spamhaus.org and get this message: This IP address is HELO'ing as "localhost.localdomain" which violates the relevant standards (specifically: RFC5321). I have tried to follow the instructions on these websites with no luck: http://www.cardiothink.com/downloads/README.spamhaus-and-blocked-email.html http://centosbeginer.wordpress.com/2011/07/12/how-to-remove-ip-in-cbl-spamhaus/ Can you please help me figure out how to configure the server? File: /etc/hosts # nameserver config # IPv4 127.0.0.1 somedomain.dk xxx.xxx.xxx.xxx server.somedomain.dk bigby # # IPv6 ::1 ip6-localhost ip6-loopback xxxx::0 ip6-localnet xxxx::0 ip6-mcastprefix xxxx::1 ip6-allnodes xxxx::2 ip6-allrouters xxxx::3 ip6-allhosts xxxx:xxx:xxx:xxxx::2 Debian-76-wheezy-64-minimal File: /etc/hostname bigby somedomain.dk is a made up domain. In reality another domain name I have on this server along with other domains. bigby is also a made up name. It is also something else in reality.

An Xml Serializable PropertyBag Dictionary Class for .NET

- by Rick Strahl

I don't know about you but I frequently need property bags in my applications to store and possibly cache arbitrary data. Dictionary<T,V> works well for this although I always seem to be hunting for a more specific generic type that provides a string key based dictionary. There's string dictionary, but it only works with strings. There's Hashset<T> but it uses the actual values as keys. In most key value pair situations for me string is key value to work off. Dictionary<T,V> works well enough, but there are some issues with serialization of dictionaries in .NET. The .NET framework doesn't do well serializing IDictionary objects out of the box. The XmlSerializer doesn't support serialization of IDictionary via it's default serialization, and while the DataContractSerializer does support IDictionary serialization it produces some pretty atrocious XML. What doesn't work? First off Dictionary serialization with the Xml Serializer doesn't work so the following fails: [TestMethod] public void DictionaryXmlSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXml(bag)); } public string ToXml(object obj) { if (obj == null) return null; StringWriter sw = new StringWriter(); XmlSerializer ser = new XmlSerializer(obj.GetType()); ser.Serialize(sw, obj); return sw.ToString(); } The error you get with this is: System.NotSupportedException: The type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] is not supported because it implements IDictionary. Got it! BTW, the same is true with binary serialization. Running the same code above against the DataContractSerializer does work: [TestMethod] public void DictionaryDataContextSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXmlDcs(bag)); } public string ToXmlDcs(object value, bool throwExceptions = false) { var ser = new DataContractSerializer(value.GetType(), null, int.MaxValue, true, false, null); MemoryStream ms = new MemoryStream(); ser.WriteObject(ms, value); return Encoding.UTF8.GetString(ms.ToArray(), 0, (int)ms.Length); } This DOES work but produces some pretty heinous XML (formatted with line breaks and indentation here): <ArrayOfKeyValueOfstringanyType xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <KeyValueOfstringanyType> <Key>key</Key> <Value i:type="a:string" xmlns:a="http://www.w3.org/2001/XMLSchema">Value</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key2</Key> <Value i:type="a:decimal" xmlns:a="http://www.w3.org/2001/XMLSchema">100.10</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key3</Key> <Value i:type="a:guid" xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/">2cd46d2a-a636-4af4-979b-e834d39b6d37</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key4</Key> <Value i:type="a:dateTime" xmlns:a="http://www.w3.org/2001/XMLSchema">2011-09-19T17:17:05.4406999-07:00</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key5</Key> <Value i:type="a:boolean" xmlns:a="http://www.w3.org/2001/XMLSchema">true</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key7</Key> <Value i:type="a:base64Binary" xmlns:a="http://www.w3.org/2001/XMLSchema">Ki1C</Value> </KeyValueOfstringanyType> </ArrayOfKeyValueOfstringanyType> Ouch! That seriously hurts the eye! :-) Worse though it's extremely verbose with all those repetitive namespace declarations. It's good to know that it works in a pinch, but for a human readable/editable solution or something lightweight to store in a database it's not quite ideal. Why should I care? As a little background, in one of my applications I have a need for a flexible property bag that is used on a free form database field on an otherwise static entity. Basically what I have is a standard database record to which arbitrary properties can be added in an XML based string field. I intend to expose those arbitrary properties as a collection from field data stored in XML. The concept is pretty simple: When loading write the data to the collection, when the data is saved serialize the data into an XML string and store it into the database. When reading the data pick up the XML and if the collection on the entity is accessed automatically deserialize the XML into the Dictionary. (I'll talk more about this in another post). While the DataContext Serializer would work, it's verbosity is problematic both for size of the generated XML strings and the fact that users can manually edit this XML based property data in an advanced mode. A clean(er) layout certainly would be preferable and more user friendly. Custom XMLSerialization with a PropertyBag Class So… after a bunch of experimentation with different serialization formats I decided to create a custom PropertyBag class that provides for a serializable Dictionary. It's basically a custom Dictionary<TType,TValue> implementation with the keys always set as string keys. The result are PropertyBag<TValue> and PropertyBag (which defaults to the object type for values). The PropertyBag<TType> and PropertyBag classes provide these features: Subclassed from Dictionary<T,V> Implements IXmlSerializable with a cleanish XML format ToXml() and FromXml() methods to export and import to and from XML strings Static CreateFromXml() method to create an instance It's simple enough as it's merely a Dictionary<string,object> subclass but that supports serialization to a - what I think at least - cleaner XML format. The class is super simple to use: [TestMethod] public void PropertyBagTwoWayObjectSerializationTest() { var bag = new PropertyBag(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42,45,66 } ); bag.Add("Key8", null); bag.Add("Key9", new ComplexObject() { Name = "Rick", Entered = DateTime.Now, Count = 10 }); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag["key"] as string == "Value"); Assert.IsInstanceOfType( bag["Key3"], typeof(Guid)); Assert.IsNull(bag["Key8"]); //Assert.IsNull(bag["Key10"]); Assert.IsInstanceOfType(bag["Key9"], typeof(ComplexObject)); } This uses the PropertyBag class which uses a PropertyBag<string,object> - which means it returns untyped values of type object. I suspect for me this will be the most common scenario as I'd want to store arbitrary values in the PropertyBag rather than one specific type. The same code with a strongly typed PropertyBag<decimal> looks like this: [TestMethod] public void PropertyBagTwoWayValueTypeSerializationTest() { var bag = new PropertyBag<decimal>(); bag.Add("key", 10M); bag.Add("Key1", 100.10M); bag.Add("Key2", 200.10M); bag.Add("Key3", 300.10M); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag.Get("Key1") == 100.10M); Assert.IsTrue(bag.Get("Key3") == 300.10M); } and produces typed results of type decimal. The types can be either value or reference types the combination of which actually proved to be a little more tricky than anticipated due to null and specific string value checks required - getting the generic typing right required use of default(T) and Convert.ChangeType() to trick the compiler into playing nice. Of course the whole raison d'etre for this class is the XML serialization. You can see in the code above that we're doing a .ToXml() and .FromXml() to serialize to and from string. The XML produced for the first example looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value>Value</value> </item> <item> <key>Key2</key> <value type="decimal">100.10</value> </item> <item> <key>Key3</key> <value type="___System.Guid"> <guid>f7a92032-0c6d-4e9d-9950-b15ff7cd207d</guid> </value> </item> <item> <key>Key4</key> <value type="datetime">2011-09-26T17:45:58.5789578-10:00</value> </item> <item> <key>Key5</key> <value type="boolean">true</value> </item> <item> <key>Key7</key> <value type="base64Binary">Ki1C</value> </item> <item> <key>Key8</key> <value type="nil" /> </item> <item> <key>Key9</key> <value type="___Westwind.Tools.Tests.PropertyBagTest+ComplexObject"> <ComplexObject> <Name>Rick</Name> <Entered>2011-09-26T17:45:58.5789578-10:00</Entered> <Count>10</Count> </ComplexObject> </value> </item> </properties> The format is a bit cleaner than the DataContractSerializer. Each item is serialized into <key> <value> pairs. If the value is a string no type information is written. Since string tends to be the most common type this saves space and serialization processing. All other types are attributed. Simple types are mapped to XML types so things like decimal, datetime, boolean and base64Binary are encoded using their Xml type values. All other types are embedded with a hokey format that describes the .NET type preceded by a three underscores and then are encoded using the XmlSerializer. You can see this best above in the ComplexObject encoding. For custom types this isn't pretty either, but it's more concise than the DCS and it works as long as you're serializing back and forth between .NET clients at least. The XML generated from the second example that uses PropertyBag<decimal> looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value type="decimal">10</value> </item> <item> <key>Key1</key> <value type="decimal">100.10</value> </item> <item> <key>Key2</key> <value type="decimal">200.10</value> </item> <item> <key>Key3</key> <value type="decimal">300.10</value> </item> </properties> How does it work As I mentioned there's nothing fancy about this solution - it's little more than a subclass of Dictionary<T,V> that implements custom Xml Serialization and a couple of helper methods that facilitate getting the XML in and out of the class more easily. But it's proven very handy for a number of projects for me where dynamic data storage is required. Here's the code: /// <summary> /// Creates a serializable string/object dictionary that is XML serializable /// Encodes keys as element names and values as simple values with a type /// attribute that contains an XML type name. Complex names encode the type /// name with type='___namespace.classname' format followed by a standard xml /// serialized format.

The code implements ReadXml and WriteXml for the IXmlSerializable implementation using old school XmlReaders and XmlWriters (because it's pretty simple stuff - no need for XLinq here). Then there are two helper methods .ToXml() and .FromXml() that basically allow your code to easily convert between XML and a PropertyBag object. In my code that's what I use to actually to persist to and from the entity XML property during .Load() and .Save() operations. It's sweet to be able to have a string key dictionary and then be able to turn around with 1 line of code to persist the whole thing to XML and back. Hopefully some of you will find this class as useful as I've found it. It's a simple solution to a common requirement in my applications and I've used the hell out of it in the short time since I created it. Resources You can find the complete code for the two classes plus the helpers in the Subversion repository for Westwind.Utilities. You can grab the source files from there or download the whole project. You can also grab the full Westwind.Utilities assembly from NuGet and add it to your project if that's easier for you.

Problem rendering VBO

- by Onno

I'm developing a game engine using OpenTK. I'm trying to get to grips with the use of VBO's. I've run into some trouble because somehow it doesn't render correctly. Thus far I've used immediate mode to render a test object, a test cube with a texture. namespace SharpEngine.Utility.Mesh { using System; using System.Collections.Generic; using OpenTK; using OpenTK.Graphics;

Since I read on the OpenTK forums that OpenTK has problems doing VA's or DL's, I decided to skip using those. Now, I've tried to change this cube to a VBO by using the same vertex, normal and tc collections, and making float arrays from them by using the coordinates in combination with uint arrays which contain the index numbers from the immediate cube.

In some other questions I read that, if I did something wrong, I'd get no rendering at all. Clearly, something gets sent to the GFX card, but it might be that I'm not sending the right data. I've tried altering the sequence in which the triangles are rendered by swapping some of the index numbers in the vert, tc and normal index arrays, but this doesn't seem to be of any effect. I'm slightly lost here. What am I doing wrong here?

xen 4.1 host priodically dropping network packets of domU

- by Dyutiman Chakraborty

I have xen 4.1 Host running on a ubuntu 12.04 LTS Server with ip 153.x.x.54. I have setup 2 VMs on it, namely, "dev.mydomain.com" and "web.mydomain.com" with ips 195.X.X.2 and 195.x.x.3 respectively. For network the VMs connect through xendbr0 (xen-bridge), and can accces the network properly. I can also login to the VMs with ssh with no issue. However when I ping any of the VMs, there is a high amount of periodic packet drop. If I the ping the xen host (dom0) there is no packet drop. Following is a output of "tcpdump | grep ICMP" on dOM0 while I was pinging one of the domU tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 05:19:55.682493 IP ABTS-North-Dynamic-226.X.X.122.airtelbroadband.in > web.mydomain.com: ICMP echo request, id 3460, seq 30, length 64 05:19:56.691144 IP

Converting linear colors to SRGB shows banding in FFmpeg

- by user1863947

When I convert an EXR file sequence with x264 using FFmpeg and convert the colorspace from linear to SRGB (with gamma 0.45454545) I get some heavy banding issues (most visible on a dark gradient). Here is the ffmpeg command I use: C:/ffmpeg.exe -y -i C:/seq_v001.%04d.exr -vf lutrgb=r=gammaval(0.45454545):g=gammaval(0.45454545):b=gammaval(0.45454545) -vcodec libx264 -pix_fmt yuv420p -preset slow -crf 18 -r 25 C:/out.mov Here is the output: ffmpeg version N-47062-g26c531c Copyright (c) 2000-2012 the FFmpeg developers built on Nov 25 2012 12:25:21 with gcc 4.7.2 (GCC) configuration:

Nginx and client certificates from hierarchical OpenSSL-based certification authorities

- by Fmy Oen

I'm trying to set up root certification authority, subordinate certification authority and to generate the client certificates signed by any of this CA that nginx 0.7.67 on Debian Squeeze will accept. My problem is that root CA signed client certificate works fine while subordinate CA signed one results in "400 Bad Request. The SSL certificate error". Step 1: nginx virtual host configuration: server { server_name test.local; access_log /var/log/nginx/test.access.log; listen 443 default ssl; keepalive_timeout 70; ssl_protocols SSLv3 TLSv1; ssl_ciphers AES128-SHA:AES256-SHA:RC4-SHA:DES-CBC3-SHA:RC4-MD5; ssl_certificate /etc/nginx/ssl/server.crt; ssl_certificate_key /etc/nginx/ssl/server.key; ssl_client_certificate /etc/nginx/ssl/client.pem; ssl_verify_client on; ssl_session_cache shared:SSL:10m; ssl_session_timeout 5m; location / { proxy_pass http://testsite.local/; } } Step 2: PKI infrastructure organization for both root and subordinate CA (based on this article): # mkdir ~/pki && cd ~/pki # mkdir rootCA subCA # cp -v /etc/ssl/openssl.cnf rootCA/ # cd rootCA/ # mkdir certs private crl newcerts; touch serial; echo 01 > serial; touch index.txt; touch crlnumber; echo 01 > crlnumber # cp -Rvp * ../subCA/ Almost no changes was made to rootCA/openssl.cnf: [ CA_default ] dir = . # Where everything is kept ... certificate = $dir/certs/rootca.crt # The CA certificate ... private_key = $dir/private/rootca.key # The private key and to subCA/openssl.cnf: [ CA_default ] dir = . # Where everything is kept ... certificate = $dir/certs/subca.crt # The CA certificate ... private_key = $dir/private/subca.key # The private key Step 3: Self-signed root CA certificate generation: # openssl genrsa -out ./private/rootca.key -des3 2048 # openssl req -x509 -new -key ./private/rootca.key -out certs/rootca.crt -config openssl.cnf Enter pass phrase for ./private/rootca.key: You are about to be asked to enter information that will be incorporated into your certificate request.
