• Recover data from quick formatted DVD-R

  - by Andrii Kalytiiuk

  I need to recover data from quick-formatted DVD-R. Please advise a free of charge option (cheap commercial tools will be ok either). Disk was partially recorded with Windows built in disk recorder and recording most likely was not complete. Afterwards I have inserted partially recorded DVD again and on Windows recorder's message box 'How to use this disk?' selected - 'use for CD/DVD player' and data was completely lost - as new recording session was started. Files of photos were recorded on disk. What I have tried so far: DiskInternals CD-DVD recovery - sees 5 jpg files but can't show preview. Tool is commercial - trial version does not allow to recover files. CDCheck - doesn't see any files and reports errors at attempt to scand DVD CD Recovery Toolbox Free - does not even recognize DVD drive ISO Buster - recognizes two files - one MP3 file for 99% of recorded size and one ARC file for about 100 KB MiniTool Power Data Recovery - Free Edition - does not see any files on DVD Stellar Phoenix CD DVD Data Recovery - does not see any files BinaryBiz Virtual Lab - sees DVD disk but needs license to browse content Please advise how is it possible to recover files from DVD.

• Weekly cron executing 2 times:

  - by yes123

  Hi guys, I have placed a .sh file that runs a php script weekly. This script should run only once, but every sunday it runs at: 1:30 am 6:50 am Any way to fix this? Add1: /etc/cron.weekly/cronweek: #!/bin/bash /usr/bin/php -f /home/my/path/to/script/cronweek.php Add2: crontab file: # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d. These files also have username fields, # that none of the other crontabs do. SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) # */1 * * * * root /usr/local/rtm/bin/rtm 35 > /dev/null 2> /dev/null

• zsh : How to list directory content with tab?

  - by Philippe CM

  I just switched from BASH to ZSH and thing are pretty good, but: when I start typing cd /usr/share/s and hit TAB, this is what I get : $ cd /usr/share/sane/ sane/ skype/ ssl-cert/ screen/ smplayer/ strigi/ seed-gtk3/ snmp/ synaptic/ sgml/ software-properties/ system-config-printer/ sgml-base/ soprano/ sysv-rc/ sgml-data/ sounds/ simple-scan/ splashy/ And this is ok. If I then hit TAB again, I get $ cd /usr/share/screen/, the next candidate, witch is also OK. (BTW, how do I cycle back to the previous candidate? Sorry, on to my question) Now what if I want to see the contents of /usr/share/screen/ now ? You now, BASH-style? The cursor is at the end of the line, will I have to ctrl-a (or home), then del del (to erase cd) then ls then ENTER? That seems like a lot of typing. (And it - possibly unnecessarily - enters the command in the history) Would not there be a key (maybe modifier-TAB? but the obvious candidates are already taken by the desktop... I digress) that would tell zsh to stop cycling through /usr/share/ and instead, just list the content /usr/share/screen/ ?

• Run a shell script using cron

  - by Blanca

  Hi! I have this FeedIndexer.sh: #!/bin/sh java -jar FeedIndexer.jar Just to run FeedIndexer.jar which is in the same directory as the .sh, I would like to run it using crontab, so I did this: # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d. These files also have username fields, # that none of the other crontabs do. SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) 01 01 * * * root run-parts --report /home/slosada/workspace/FeedIndexer/target/FeedIndexer.sh # But I don't know how to run it. Have i made any mistake?? Thank you!

• Upload Certificate and Key to RUEI in order to decrypt SSL traffic

  - by stefan.thieme(at)oracle.com

  So you want to monitor encrypted traffic with your RUEI collector ?Actually this is an easy thing if you follow the lines below...I will start out with creating a pair of snakeoil (so called self-signed) certificate and key with the make-ssl-cert tool which comes pre-packaged with apache only for the purpose of this example.$ sudo make-ssl-cert generate-default-snakeoil$ sudo ls -l /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/private/ssl-cert-snakeoil.key-rw-r--r-- 1 root root     615 2010-06-07 10:03 /etc/ssl/certs/ssl-cert-snakeoil.pem-rw-r----- 1 root ssl-cert 891 2010-06-07 10:03 /etc/ssl/private/ssl-cert-snakeoil.keyRUEI Configuration of Security SSL Keys You will most likely get these two files from your Certificate Authority (CA) and/or your system administrators should be able to extract this from your WebServer or LoadBalancer handling SSL encryption for your infrastructure.Now let's look at the content of these two files, the certificate (apache assumes this is in PEM format) is called a public key and the private key is used by the apache server to encrypt traffic for a client using the certificate to initiate the SSL connection with the server.In case you already know that these two match, you simply have to paste them in one text file and upload this text file to your RUEI instance.$ sudo cat /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/private/ssl-cert-snakeoil.key > /tmp/ruei.cert_and_key$ sudo cat /tmp/ruei.cert_and_key -----BEGIN CERTIFICATE----- MIIBmTCCAQICCQD7O3XXwVilWzANBgkqhkiG9w0BAQUFADARMQ8wDQYDVQQDEwZ1 YnVudHUwHhcNMTAwNjA3MDgwMzUzWhcNMjAwNjA0MDgwMzUzWjARMQ8wDQYDVQQD EwZ1YnVudHUwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBALbs+JnI+p+K7Iqa SQZdnYBxOpdRH0/9jt1QKvmH68v81h9+f1Z2rVR7Zrd/l+ruE3H9VvuzxMlKuMH7 qBX/gmjDZTlj9WJM+zc0tSk+e2udy9he20lGzTxv0vaykJkuKcvSWNk4WE9NuAdg IHZvjKgoTSVmvM1ApMCg69nyOy97AgMBAAEwDQYJKoZIhvcNAQEFBQADgYEAk2rv VEkxR1qPSpJiudDuGUHtWKBKWiWbmSwI3REZT+0vG+YDG5a55NdxgRk3zhQntqF7 gNYjKxblBByBpY7W0ci00kf7kFgvXWMeU96NSQJdnid/YxzQYn0dGL2rSh1dwdPN NPQlNSfnEQ1yxFevR7aRdCqTbTXU3mxi8YaSscE= -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- MIICXgIBAAKBgQC27PiZyPqfiuyKmkkGXZ2AcTqXUR9P/Y7dUCr5h+vL/NYffn9W dq1Ue2a3f5fq7hNx/Vb7s8TJSrjB+6gV/4Jow2U5Y/ViTPs3NLUpPntrncvYXttJ Rs08b9L2spCZLinL0ljZOFhPTbgHYCB2b4yoKE0lZrzNQKTAoOvZ8jsvewIDAQAB AoGBAJ7LCWeeUwnKNFqBYmD3RTFpmX4furnal3lBDX0945BZtJr0WZ/6N679zIYA aiVTdGfgjvDC9lHy3n3uctRd0Jqdh2QoSSxNBhq5elIApNIIYzu7w/XI/VhGcDlA b6uadURQEC2q+M8YYjw3mwR2omhCWlHIViOHe/9T8jfP/8pxAkEA7k39WRcQildH DFKcj7gurqlkElHysacMTFWf0ZDTEUS6bdkmNXwK6mH63BlmGLrYAP5AMgKgeDf8 D+WRfv8YKQJBAMSCQ7UGDN3ysyfIIrdc1RBEAk4BOrKHKtD5Ux0z5lcQkaCYrK8J DuSldreN2yOhS99/S4CRWmGkTj04wRSnjwMCQQCaR5mW3QzTU4/m1XEQxsBKSdZE 2hMSmsCmhuSyK13Kl0FPLr/C7qyuc4KSjksABa8kbXaoKfUz/6LLs+ePXZ2JAkAv +mIPk5+WnQgS4XFgdYDrzL8HTpOHPSs+BHG/goltnnT/0ebvgXWqa5+1pyPm6h29 PrYveM2pY1Va6z1xDowDAkEAttfzAwAHz+FUhWQCmOBpvBuW/KhYWKZTMpvxFMSY YD5PH6NNyLfBx0J4nGPN5n/f6il0s9pzt3ko++/eUtWSnQ== -----END RSA PRIVATE KEY----- Simply click on the add new key and browse for the cert_and_key file on your desktop which you concatenated earlier using any text editor. You may need to add a passphrase in order to decrypt the RSA key in some cases (it should tell you BEGIN ENCRYPTED PRIVATE KEY in the header line). I will show you the success screen after uploading the certificate to RUEI. You may want to restart your collector once you have uploaded all the certificate/key pairs you want to use in order to make sure they get picked up asap.You should be able to see the number of SSL Connections rising in the Collector statistics screen below. The figures for decrypt errors should slowly go down and the usage figures for your encryption algortihm on the subsequent SSL Encryption screen should go up. You should be 100% sure everything works fine by now, otherwise see below to distinguish the remaining 1% from your 99% certainty.Verify Certificate and Key are matchingYou can compare the modulus of private key and public certificate and they should match in order for the key to fit the lock. You only want to make sure they both fit each other.We are actually interested only in the following details of the two files, which can be determined by using the -subject, -dates and -modulus command line switches instead of the complete -text output of the x509 certificate/rsa key contents.$ sudo openssl x509 -noout -subject -in /etc/ssl/certs/ssl-cert-snakeoil.pemsubject= /CN=ubuntu$ sudo openssl x509 -noout -dates -in /etc/ssl/certs/ssl-cert-snakeoil.pemnotBefore=Jun  7 08:03:53 2010 GMTnotAfter=Jun  4 08:03:53 2020 GMT$ sudo openssl x509 -noout -modulus -in /etc/ssl/certs/ssl-cert-snakeoil.pem Modulus=B6ECF899C8FA9F8AEC8A9A49065D9D80713A97511F4FFD8EDD502AF987EBCBFCD61F7E7F5676AD547B66B77F97EAEE1371FD56FBB3C4C94AB8C1FBA815FF8268C3653963F5624CFB3734B5293E7B6B9DCBD85EDB4946CD3C6FD2F6B290992E29CBD258D938584F4DB8076020766F8CA8284D2566BCCD40A4C0A0EBD9F23B2F7B $ sudo openssl rsa -noout -modulus -in /etc/ssl/private/ssl-cert-snakeoil.keyModulus=B6ECF899C8FA9F8AEC8A9A49065D9D80713A97511F4FFD8EDD502AF987EBCBFCD61F7E7F5676AD547B66B77F97EAEE1371FD56FBB3C4C94AB8C1FBA815FF8268C3653963F5624CFB3734B5293E7B6B9DCBD85EDB4946CD3C6FD2F6B290992E29CBD258D938584F4DB8076020766F8CA8284D2566BCCD40A4C0A0EBD9F23B2F7BAs you can see the modulus matches exactly and we have the proof that the certificate has been created using the private key. OpenSSL Certificate and Key DetailsAs I already told you, you do not need all the greedy details, but in case you want to know it in depth what is actually in those hex-blocks can be made visible with the following commands which show you the actual content in a human readable format.Note: You may not want to post all the details of your private key =^) I told you I have been using a self-signed certificate only for showing you these details.$ sudo openssl rsa -noout -text -in /etc/ssl/private/ssl-cert-snakeoil.keyPrivate-Key: (1024 bit)modulus:    00:b6:ec:f8:99:c8:fa:9f:8a:ec:8a:9a:49:06:5d:    9d:80:71:3a:97:51:1f:4f:fd:8e:dd:50:2a:f9:87:    eb:cb:fc:d6:1f:7e:7f:56:76:ad:54:7b:66:b7:7f:    97:ea:ee:13:71:fd:56:fb:b3:c4:c9:4a:b8:c1:fb:    a8:15:ff:82:68:c3:65:39:63:f5:62:4c:fb:37:34:    b5:29:3e:7b:6b:9d:cb:d8:5e:db:49:46:cd:3c:6f:    d2:f6:b2:90:99:2e:29:cb:d2:58:d9:38:58:4f:4d:    b8:07:60:20:76:6f:8c:a8:28:4d:25:66:bc:cd:40:    a4:c0:a0:eb:d9:f2:3b:2f:7bpublicExponent: 65537 (0x10001)privateExponent:    00:9e:cb:09:67:9e:53:09:ca:34:5a:81:62:60:f7:    45:31:69:99:7e:1f:ba:b9:da:97:79:41:0d:7d:3d:    e3:90:59:b4:9a:f4:59:9f:fa:37:ae:fd:cc:86:00:    6a:25:53:74:67:e0:8e:f0:c2:f6:51:f2:de:7d:ee:    72:d4:5d:d0:9a:9d:87:64:28:49:2c:4d:06:1a:b9:    7a:52:00:a4:d2:08:63:3b:bb:c3:f5:c8:fd:58:46:    70:39:40:6f:ab:9a:75:44:50:10:2d:aa:f8:cf:18:    62:3c:37:9b:04:76:a2:68:42:5a:51:c8:56:23:87:    7b:ff:53:f2:37:cf:ff:ca:71prime1:    00:ee:4d:fd:59:17:10:8a:57:47:0c:52:9c:8f:b8:    2e:ae:a9:64:12:51:f2:b1:a7:0c:4c:55:9f:d1:90:    d3:11:44:ba:6d:d9:26:35:7c:0a:ea:61:fa:dc:19:    66:18:ba:d8:00:fe:40:32:02:a0:78:37:fc:0f:e5:    91:7e:ff:18:29prime2:    00:c4:82:43:b5:06:0c:dd:f2:b3:27:c8:22:b7:5c:    d5:10:44:02:4e:01:3a:b2:87:2a:d0:f9:53:1d:33:    e6:57:10:91:a0:98:ac:af:09:0e:e4:a5:76:b7:8d:    db:23:a1:4b:df:7f:4b:80:91:5a:61:a4:4e:3d:38:    c1:14:a7:8f:03exponent1:    00:9a:47:99:96:dd:0c:d3:53:8f:e6:d5:71:10:c6:    c0:4a:49:d6:44:da:13:12:9a:c0:a6:86:e4:b2:2b:    5d:ca:97:41:4f:2e:bf:c2:ee:ac:ae:73:82:92:8e:    4b:00:05:af:24:6d:76:a8:29:f5:33:ff:a2:cb:b3:    e7:8f:5d:9d:89exponent2:    2f:fa:62:0f:93:9f:96:9d:08:12:e1:71:60:75:80:    eb:cc:bf:07:4e:93:87:3d:2b:3e:04:71:bf:82:89:    6d:9e:74:ff:d1:e6:ef:81:75:aa:6b:9f:b5:a7:23:    e6:ea:1d:bd:3e:b6:2f:78:cd:a9:63:55:5a:eb:3d:    71:0e:8c:03coefficient:    00:b6:d7:f3:03:00:07:cf:e1:54:85:64:02:98:e0:    69:bc:1b:96:fc:a8:58:58:a6:53:32:9b:f1:14:c4:    98:60:3e:4f:1f:a3:4d:c8:b7:c1:c7:42:78:9c:63:    cd:e6:7f:df:ea:29:74:b3:da:73:b7:79:28:fb:ef:    de:52:d5:92:9d$ sudo openssl x509 -noout -text -in /etc/ssl/certs/ssl-cert-snakeoil.pemCertificate:    Data:        Version: 1 (0x0)        Serial Number:            fb:3b:75:d7:c1:58:a5:5b        Signature Algorithm: sha1WithRSAEncryption        Issuer: CN=ubuntu        Validity            Not Before: Jun  7 08:03:53 2010 GMT            Not After : Jun  4 08:03:53 2020 GMT        Subject: CN=ubuntu        Subject Public Key Info:            Public Key Algorithm: rsaEncryption            RSA Public Key: (1024 bit)                Modulus (1024 bit):                    00:b6:ec:f8:99:c8:fa:9f:8a:ec:8a:9a:49:06:5d:                    9d:80:71:3a:97:51:1f:4f:fd:8e:dd:50:2a:f9:87:                    eb:cb:fc:d6:1f:7e:7f:56:76:ad:54:7b:66:b7:7f:                    97:ea:ee:13:71:fd:56:fb:b3:c4:c9:4a:b8:c1:fb:                    a8:15:ff:82:68:c3:65:39:63:f5:62:4c:fb:37:34:                    b5:29:3e:7b:6b:9d:cb:d8:5e:db:49:46:cd:3c:6f:                    d2:f6:b2:90:99:2e:29:cb:d2:58:d9:38:58:4f:4d:                    b8:07:60:20:76:6f:8c:a8:28:4d:25:66:bc:cd:40:                    a4:c0:a0:eb:d9:f2:3b:2f:7b                Exponent: 65537 (0x10001)    Signature Algorithm: sha1WithRSAEncryption        93:6a:ef:54:49:31:47:5a:8f:4a:92:62:b9:d0:ee:19:41:ed:        58:a0:4a:5a:25:9b:99:2c:08:dd:11:19:4f:ed:2f:1b:e6:03:        1b:96:b9:e4:d7:71:81:19:37:ce:14:27:b6:a1:7b:80:d6:23:        2b:16:e5:04:1c:81:a5:8e:d6:d1:c8:b4:d2:47:fb:90:58:2f:        5d:63:1e:53:de:8d:49:02:5d:9e:27:7f:63:1c:d0:62:7d:1d:        18:bd:ab:4a:1d:5d:c1:d3:cd:34:f4:25:35:27:e7:11:0d:72:        c4:57:af:47:b6:91:74:2a:93:6d:35:d4:de:6c:62:f1:86:92:        b1:c1The above output can also be seen if you direct your browser client to your website and check the certificate sent by the server to your browser. You will be able to lookup all the details including the validity dates, subject common name and the public key modulus.Capture an SSL connection using WiresharkAnd as you would have expected, looking at the low-level tcp data that has been exchanged between the client and server with a tcp-diagnostics tool (i.e. wireshark/tcpdump) you can also see the modulus in there.These were the settings I used to capture all traffic on the local loopback interface, matching the filter expression: tcp and ip and host 127.0.0.1 and port 443. This tells Wireshark to leave out any other information, I may not have been interested in showing you.

• Secure wipe of a hard drive using WinPE.

However, these applications are typically expensive or unreliable.  Plus, if you have a laptop or lack a secondary computer to put the hard drive into – how on earth do you wipe it quickly and easily while still conforming to a 7 pass rule (this means that every possible bit on the hard drive is set to 0 and then to 1 seven times in a row)?  Yes, one pass should be enough – as turning every bit from a 1 to a zero will wipe the data from existence.  But, we’re dealing with tinfoil hat wearing types here people.  DOD standards dictate at least 3 passes, and typically 7 is the preferred amount.  I’m not going to argue about data recovery.  I have been told to use 7 passes, and so I will.  So say we all! Quite some time ago I used to make a BartPE XP-based boot cd for the original purpose of securely wiping data.  I loved BartPE and integrated so many plugins into my builds that I could do pretty much anything directly from CD.  Reset passwords, uninstall security updates, wipe drives, chkdsk, remove spyware, install Windows, etc.  However, with the newer multi-core systems and new chipsets coming out from vendors, I found that BartPE was rather difficult to keep up to date.  I have since switched to WinPE 3.0 (Windows Preinstallation Environment). http://technet.microsoft.com/en-us/library/cc748933(WS.10).aspx  It is fairly simple to create your own CD, and I have made a few helpful scripts to easily integrate drivers and rebuild the ISO file for you.  I’ll cover making your own boot CD utilizing WinPE 3.0 in a later post – I can talk about WinPE forever and need to collect my thoughts!!  My wife loves talking about WinPE almost as much as talking about Doctor Who.  Wait, did I say loves?  Hmmmm, I may have meant loathes. The topic at hand?  Right. Wiping a drive! I must have drunk too much coffee this morning.  I like to use a simple batch script that calls a combination of diskpart.exe from Microsoft® and Sdelete.exe created by our friend Mark Russinovich. http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx All of the following files are located within the same directory on my WinPE boot CD. Here are the contents of wipe_me.bat, script.txt and sdelete.reg. Wipe_me.bat:   @echo off echo. echo     I will completely wipe the local hard drives using echo     7 individual wipes.

• Symfony2 same form, different entities NOT related

  - by user1381537

  I'm trying to write one form for submitting against MySQL DB, but I can't get it working, I've tried a lot of things (separate forms, create an ->add('foo', new foo()) to a field, and trying to parse plain SQL with a normal HTML form is my only solution, which is obviously not the best. This is my DB structure: As you can see I need to insert the comments textarea to ticketcomments among the user who wrote it, etc. On crmentity the description field. Then on ticketcf the fields that I need to submit from form, are this (because you wont know if I don't tell you because of the field names): tcf.cf594 AS Type, tcf.cf675 AS Suscription, tcf.cf770 AS ID_PRODUCT, tcf.cf746 AS NotificationDate, tcf.cf747 AS ResponseDate, tcf.cf748 AS ResolutionDate, And, of course, every table needs to have the same ticketid id for the submitted form, so we can retrieve it with one simple query. It will be easy to do with plain SQL instead of using DQL and Symfony2 forms, but is not a good way to do it. Also, here's my "Ticket list" query, if you need it to have it more clear... SELECT t.ticketNo AS Ticket, t.title AS Asunto, t.status AS Estado, t.updateLog AS LOG, t.hours AS Horas, t.solution AS Solucion, t.priority AS Prioridad, tcf.cf594 AS Tipo, tcf.cf675 AS Suscripcion, tcf.cf770 AS IDPROD, tcf.cf746 AS F_Noti, tcf.cf747 AS F_Resp, tcf.cf748 AS F_Reso, CONCAT (cd.firstname, cd.lastname) AS Contacto, crm.description AS Descripcion, crm.crmid AS id FROM WbsGoclientsBundle:VtigerTroubletickets t INNER JOIN WbsGoclientsBundle:VtigerTicketcf tcf WITH t.ticketid = tcf.ticketid INNER JOIN WbsGoclientsBundle:VtigerContactdetails cd WITH t.parentId = cd.contactid INNER JOIN WbsGoclientsBundle:VtigerCrmentity crm WITH t.ticketid = crm.crmid WHERE t.parentId IN ( SELECT cd1.contactid FROM WbsGoclientsBundle:VtigerContactdetails cd1 WHERE cd1.accountid = ( SELECT cd2.accountid FROM WbsGoclientsBundle:VtigerContactdetails cd2 WHERE cd2.contactid = :contactid)) AND t.status <> \'Closed\' And also "Ticket details" query (which is not in DQL format yet, only SQL) is so simple, it only retrieve the comments field and createdtime from ticketcomments appended to this query so we have all the fields... Thank you. This is a test form, using troubletickets and ticketcomments, it's returning errores because I can't set a comments field because troubletickets doesn't has it, but I need that field to be submitted to ticketcomments ... VtigerTicketcommentsType <?php namespace WbsGo\clientsBundle\Form\Type; use Symfony\Component\Form\AbstractType, Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class VtigerTicketcommentsType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('ticketid') ->add('comments') ->add('ownerid') ->add('ownertype') ->add('createdtype') ; } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'WbsGo\clientsBundle\Entity\VtigerTicketcomments' )); } public function getName() { return 'comments'; } } OpenTicketType.php <?php namespace WbsGo\clientsBundle\Form; use Symfony\Component\Form\AbstractType, Symfony\Component\Form\FormBuilderInterface ; use WbsGo\clientsBundle\Form\Type\VtigerTicketcommentsType; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class OpenTicketType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('title') ->add('priority') ->add('solution') ->add('comments', 'collection', array( 'type' => new VtigerTicketcommentsType() )) ; } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'WbsGo\clientsBundle\Entity\VtigerTroubletickets' )); } public function getName() { return 'ticket'; } } TicketController.php <?php namespace WbsGo\clientsBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use WbsGo\clientsBundle\Entity\VtigerTroubletickets; use WbsGo\clientsBundle\Entity\VtigerTicketcomments; use WbsGo\clientsBundle\Form\OpenTicketType; use Symfony\Component\HttpFoundation\Request; class TicketController extends Controller { public function indexAction() { $em = $this->getDoctrine()->getManager(); $tickets = $em ->getRepository('WbsGoclientsBundle:VtigerTroubletickets') ->findAllOpenByCustomerId($this->getUser()->getId()); $userdata = $this->getDoctrine()->getManager() ->getRepository('WbsGoclientsBundle:VtigerContactdetails') ->findContact($this->getUser()->getId()); return $this ->render('WbsGoclientsBundle:Ticket:index.html.twig', array('tickets' => $tickets, 'userdata' => $userdata)); } public function addAction() { $assets = $this->getDoctrine()->getManager() ->getRepository('WbsGoclientsBundle:VtigerAssets') ->findAssetByAccountId($this->getUser()->getId()); $assetlist = array(); foreach ($assets as $key => $v) { $assetlist[$key] = $key; } $form = $this->createForm(new OpenTicketType(), new VtigerTroubletickets()); return $this ->render('WbsGoclientsBundle:Ticket:add.html.twig', array('form' => $form->createView(), 'assets' => $assets,)); } } This is the error Symfony2 is returning Neither the property "comments" nor one of the methods "getComments()", "isComments()", "hasComments()", "_get()" or "_call()" exist and have public access in class "WbsGo\clientsBundle\Entity\VtigerTroubletickets". EDIT 2 This code is actually rendering my forms, but I need help in order to submit each XXXType form to its corresponding table. public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('descripcion') ->add('prioridad') ->add('solucion') ->add('comment', new VtigerTicketcommentsType() ) ->add('contacto') ->add('suscripcion') ->add('producto', 'entity', array( 'class' => 'WbsGo\clientsBundle\Entity\VtigerAssets', 'property' => 'assetname', 'empty_value' => '--SELECT--', 'query_builder' => function(\WbsGo\clientsBundle\Entity\VtigerAssetsRepository $repository) { //return $repository->findAssetByAccountId($this->customerId); return $repository->createQueryBuilder('a') ->select('a') ->where('a.account = (SELECT cd.accountid FROM WbsGoclientsBundle:VtigerContactdetails cd WHERE cd.contactid = ?1)') ->setParameter(1, $this->customerId); } ) ) ->add('hardware') ->add('backup') ->add('web') ->add('restore') ->add('customerId') ; } I also removed ->add('ticketid') from VtigerTicketcommentsType.php because it has relationship and is not needed. it's auto_incremental and must be generated once everything is submitted.

• Linux Mint 10 LXDE computer to act as LTSP Server without luck

• Can't install Perl DBD module on Ubuntu (for Bugzilla)

  Trying to install bugzilla-4.2.2 on Ubuntu 12.04. When I run checksetup.pl I get the following error: YOU MUST RUN ONE OF THE FOLLOWING COMMANDS (depending on which database you use): PostgreSQL: /usr/bin/perl install-module.pl DBD::Pg MySQL: /usr/bin/perl install-module.pl DBD::mysql SQLite: /usr/bin/perl install-module.pl DBD::SQLite Oracle: /usr/bin/perl install-module.pl DBD::Oracle To attempt an automatic install of every required and optional module with one command, do: /usr/bin/perl install-module.pl --all I have installed MySQL via XAMPP so I run: /urs/bin/perl install-module.pl DBD::mysql And get the following error: perl Makefile.PL --testuser=username Can't exec "mysql_config": No such file or directory at Makefile.PL line 479.

Again I need MySQL because thats what XAMPP uses and because I prefer MySQL regardless. I have a feeling it has something to do with this notest pragma error. Any ideas? Thanks in advance!

• LED Monitor brightness

  - by Yuval

  I am in the market for a new monitor. I've been looking around and it seems that the general brightness for monitors is between 250-320 cd/m2. After hours of searching, I narrowed it down to the LG W2453V-PF vs. the LG E2350V-SN The W2453V-PF is not LED backlit yet it has a brightness level of 310 cd/m2 and a response time of 2ms. The E2350V-SN, on the other hand, has a brightness level of 250 cd/m2 and a response time of 5ms but it is LED backlit. My questions are, looking at these overall specs: Which monitor is better? What makes LED backlight better? Is the LED backlight worth the decreased brightness level? Thanks! p.s. if you have any other comparable monitor suggestions (that are not samsung - I read their customer service is absolutely terrible), feel free to share. thanks!

• Make bootable iso with grub chainloading

  - by hlovdal

  My parents' pc has windows 7's boot manager installed at MBR and grub2 is installed on /dev/sda2 (booting linux on /dev/sda2). I want to make a bootable cd so that when booted from it just chainloads into the boot manager on the second partition. I assume using grub rather than grub2 for this will be simpler, using the configuration timeout=0 hiddenmenu default=0 title grub2 (/dev/sda2) rootnoverify (hd0,1) chainloader (hd0,1)+1 I know I can make a bootable linux cd in various ways, but that is not what I want. I just want to put grub/grub2 on the cd, no kernels or programs. The question is how do I make the iso file? I have found some references to installing on a floppy or usb disk, but all those assume the device is present when running the grub install commands. A iso file is different.

• Setting alias in Windows PowerShell

  - by westsider

  In PowerShell, I type: PS C: sal cdp "cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'" I get no error from this, and PS C: gal cdp shows definition as: cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects' But, when I try to use cdp, I get this: Cannot resolve alias 'cdp' because it refers to term 'cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'', which is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again. At line:1 char:4 + cdp <<<<  + CatergoryInfo   : ObjectNotFound (dsp:String) [], CommandNotFoundException  + FullyQualifiedErrorId   : AliasNotResolvedException I am guessing that this is trivially easy. So I apologize in advance if that is the case. I have googled and googled and have also read through Windows PowerShell Cookbook.

• Symfony forms question (restoring selected value of a dynamically populated sfWidgetFormSelect widge

  - by Stick it to THE MAN

  I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10. I have developed a form that dynamically populates a select widget with cities in a selected country, using AJAX. Before the data entered on the form is saved, I validate the form. If validation fails, the form is presented back to the user for correction. However, because the country list is dynamically generated, the form that is presented for correction does not have a valid city selected (it is empty, since the country widget has not changed yet). This is inconvenient for the user, because it means they have to select ANOTHER country (so the change event is fired), and then change back to the original country they selected, then FINALLY select the city which they had last selected. All of this is forced on the user because another (possibly unrelated) field did not vaildate. I tried $form-getValue('widget_name'), called immediately after $form-bind(), but it seems (infact, IIRC, if form fails to validate, all the values are reset to null) - so that does not work. I am currently trying a nasty hack which involves the use of directly accesing the input (i.e. tainted) data via $_POST, and setting them into a flash variable - but I feel its a very nasty hack) What I'm trying to do is a common use case scenario - is there a better way to do this, than hacking around with $_POST etc?

Note: I'm not experienced with .dll's outside of .NET's ez pz assembly architechture, definitely a n00b.

• Trying to issue a mouseclick event on a QWebElement in QWebView QtWebKit

  - by Bad Man

  I'm trying to send a mouse click event on a certain element in the QtWebKit DOM but I'm obviously doing it wrong: QWebElement el=this->page()->mainFrame()->findFirstElement("input[type=submit]"); el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &releaseEvent); Any ideas?

• Why does Perl's readdir() cache directory entries?

  - by Frank Straetz

  For some reason Perl keeps caching the directory entries I'm trying to read using readdir: opendir(SNIPPETS, $dir_snippets); # or die... while ( my $snippet = readdir(SNIPPETS) ) { print ">>>".$snippet."\n"; } closedir(SNIPPETS); Since my directory contains two files, test.pl and test.man, I'm expecting the following output: . .. test.pl test.man Unfortunately Perl returns a lot of files that have since vanished, for example because I tried to rename them. After I move test.pl to test.yeah Perl will return the following list: . .. test.pl test.yeah test.man What's the reason for this strange behaviour? The documentation for opendir, readdir and closedir doesn't mention some sort of caching mechanism. "ls -l" clearly lists only two files.

• Warning: Memcache::connect(0memcache.connect0): Can't connect to localhost:11211, Connection refuse

  - by Stick it to THE MAN

  I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10. I am incorporating memcache to the website. I have modified the setup() method in apps/frontend/ProjectConfiguration.class.php like this: class ProjectConfiguration { public function setup() { // original SF generated code here .. require_one sfConfig::get('sf_lib_dir').'/MyCache.class.php'; myCache::init(); } } my cache singleton is implemented something like this: class MyCache { private static memcache = null; private static inited = false; public static init() { if (self::$inited) return; self::$memcache = new Memcache(); if (self::$memcache->connect('localhost', 11211) { // Do some stuff .. self::$inited = true; } } } Warning: Memcache::connect(0memcache.connect0): Can't connect to localhost:11211, Connection refused(111) in /path_to_class/MyCache.class.php This happens for both CLI (e.g. running SF tasks) or for web access through the browser. Does anyone know how to resolve this (I suspect its something to do with Linux user privileges). As an aside, I am aware that SF prvoides an sfAPCache wrapper class for cacheing. I am intentionally not using it for two reasons: I cannot find any comprehensive (and up to date) docs on this class I want to learn the memcache API directly, since I will be accesing it from other languages.

• How to remove a partition on a USB drive?

  - by Nathan Long

  I got a free promotional USB stick that I want to format for my own purposes. When I inserted it, it automatically opened a browser and launched a web site. I have since disabled autoplay on this computer so that nothing launches when the stick is inserted. But it still shows up as two separate drives, and one of them is a "CD Drive" that I can't format. How can a USB stick contain a "CD Drive?" And more to the point, how can I remove this partition using Windows XP or Ubuntu? Update I previously asked for an XP solution, but finding none, I have tried Ubuntu, also without success. Gparted doesn't see the "CD" portion as a device at all, and from bash, any chmod changes I try tell me that the file system is read-only. Any ideas?
