• SQL Developer at Oracle Open World 2012

  - by thatjeffsmith

  We have a lot going on in San Francisco this fall. One of the most personal exciting bits, for what will be my 4th or 5th Open World, is that this will be my FIRST as a member of Team Oracle. I’ve presented once before, but most years it was just me pressing flesh at the vendor booths. After 3-4 days of standing and talking, you’re ready to just go home and not do anything for a few weeks. This time I’ll have a chance to walk around and talk with our users and get a good idea of what’s working and what’s not. Of course it will be a great opportunity for you to find us and get to know your SQL Developer team! 3.4 miles across and back – thanks Ashley for signing me up for the run! This year is going to be a bit crazy. Work wise I’ll be presenting twice, working a booth, and proctoring several of our Hands-On Labs. The fun parts will be equally crazy though – running across the Bay Bridge (I don’t run), swimming the Bay (I don’t swim), having my wife fly out on Wednesday for the concert, and then our first WhiskyFest on Friday (I do drink whisky though.) But back to work – let’s talk about EVERYTHING you can expect from the SQL Developer team. Booth Hours We’ll have 2 ‘demo pods’ in the Exhibition Hall over at Moscone South. Look for the farm of Oracle booths, we’ll be there under the signs that say ‘SQL Developer.’ There will be several people on hand, mostly developers (yes, they still count as people), who can answer your questions or demo the latest features. Come by and say ‘Hi!’, and let us know what you like and what you think we can do better. Seriously. Monday 10AM – 6PM Tuesday 9:45AM – 6PM Wednesday 9:45AM – 4PM Presentations Stop by for an hour, pull up a chair, sit back and soak in all the SQL Developer goodness. You’ll only have to suffer my bad jokes for two of the presentations, so please at least try to come to the other ones. We’ll be talking about data modeling, migrations, source control, and new features in versions 3.1 and 3.2 of SQL Developer and SQL Developer Data Modeler. Day Time Event Monday 10:454:45 What’s New in SQL Developer Why Move to Oracle Application Express Listener Tueday 10:1511:455:00 Using Subversion in Oracle SQL Developer Data Modeler Oracle SQL Developer Tips & Tricks Database Design with Oracle SQL Developer Data Modeler Wednesday 11:453:30 Migrating Third-Party Databases and Applications to Oracle Exadata 11g Enterprise Options and Management Packs for Developers Hands On Labs (HOLs) The Hands On Labs allow you to come into a classroom environment, sit down at a computer, and run through some exercises. We’ll provide the hardware, software, and training materials. It’s self-paced, but we’ll have several helpers walking around to answer questions and chat up any SQL Developer or database topic that comes to mind. If your employer is sending you to Open World for all that great training, the HOLs are a great opportunity to capitalize on that. They are only 60 minutes each, so you don’t have to worry about burning out. And there’s no homework! Of course, if you do want to take the labs home with you, many are already available via the Developer Day Hands-On Database Applications Developer Lab. You will need your own computer for those, but we’ll take care of the rest. Wednesday PL/SQL Development and Unit Testing with Oracle SQL Developer 10:15 Performance Tuning with Oracle SQL Developer 11:45 Thursday The Soup to Nuts of Data Modeling with Oracle SQL Developer Data Modeler 11:15 Some Parting Advice Always wanted to meet your favorite Oracle authors, speakers, and thought-leaders? Don’t be shy, walk right up to them and introduce yourself. Normal social rules still apply, but at the conference everyone is open and up for meeting and talking with attendees. Just understand if there’s a line that you might only get a minute or two. It’s a LONG conference though, so you’ll have plenty of time to catch up with everyone. If you’re going to be around on Tuesday evening, head on over to the OTN Lounge from 4:30 to 6:30 and hang out for our Tweet Meet. That’s right, all the Oracle nerds on Twitter will be there in one place. Be sure to put your Twitter handle on your name tag so we know who you are!

• Error 2013: Lost connection to MySQL server during query when executing CHECK TABLE FOR UPGRADE

  - by Dean Richardson

  I just upgraded Ubuntu from 11.10 to 12.04. My rails app now returns the (passenger) error "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) (Mysql2::Error)". I get a similar error when I try to access mysql at the command line on my Ubuntu server using mysql -u root -p. I have mysql-server 5.5 installed. I've checked and mysql is not running. When I try to restart it, it fails. Here are some key lines from the tail of /var/log/syslog after an attempted restart: dean@dgwjasonfried:/etc/mysql$ tail -f /var/log/syslog Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Looking for 'mysqlcheck' as: /usr/bin/mysqlcheck Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Running 'mysqlcheck' with connection arguments: '--port=3306' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Running 'mysqlcheck' with connection arguments: '--port=3306' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: /usr/bin/mysqlcheck: Got error: 2013: Lost connection to MySQL server during query when executing 'CHECK TABLE ...

I reviewed the related questions here and attempted some of the fixes offered but to no avail. Thanks! Dean Richardson Update: Thanks to quanta's suggestion, I looked at the /var/log/mysql/error.log file. I found error messages relating to pointers, fatal signals, and more stuff that I really couldn't make much sense of. I also found mysql man page references, however. One suggested that I try starting mysqld with the --innodb_force_recovery=# option, then attempt to dump (or drop) the offending/corrupted database or table. I worked through the escalating option levels one-by-one (innodb_force_recovery=1, innodb_force_recovery=2, etc.) This allowed me to successfully run mysql -u root -p from the command line and execute several commands. I was able to run queries on my production database, but any attempt to query, dump, or even drop my development database raised an error and led to me losing the connection to mysql. So I've made progress, but until I'm somehow able to drop or repair my development db I'm still unable to get my app to load. Any further advice or suggestions? Thanks! Dean Update: Right after running sudo mysqld --innodb_force_recover=1 from the command line, the error.log contains this: Right after retrying sudo mysqld --innodb_force_recover=1, The error.log file shows this: 130308 4:55:39 [Note] Plugin 'FEDERATED' is disabled. 130308 4:55:39 InnoDB: The InnoDB memory heap is disabled 130308 4:55:39 InnoDB: Mutexes and rw_locks use GCC atomic builtins 130308 4:55:39 InnoDB: Compressed tables use zlib 1.2.3.4 130308 4:55:39 InnoDB: Initializing buffer pool, size = 128.0M 130308 4:55:39 InnoDB: Completed initialization of buffer pool 130308 4:55:39 InnoDB: highest supported file format is Barracuda.

• Mounting a TrueCrypt volume over FTP

  - by Maxim Zaslavsky

  Is it possible to mount a TrueCrypt volume file over FTP? Here's how TrueCrypt works with a local file: User inputs path to volume file, enters password TrueCrypt verifies that the password is correct (probably by decrypting the very first part of the volume file?) TrueCrypt reads the directory listing from the volume file and mounts the volume. However, in this step, TrueCrypt does NOT process the whole volume file. The user browses the directory listing and opens a file. TrueCrypt reads only the part of the volume file that contains the file the user wants, and then decrypts it. Once again, TrueCrypt doesn't process the whole volume file - it only reads part of it. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file. I'm pretty sure it should be possible to mount a volume over FTP, without undermining security and without having to transfer the whole volume file just to read one small part of the volume. Here's how I imagine it: User inputs FTP path to volume file, enters FTP login information, enters password to volume TrueCrypt downloads the very first part of the volume file and verifies that the password is correct TrueCrypt downloads the part of the volume file that contains the directory listing - the data is sent encrypted over FTP and is decrypted locally. The user browses the directory listing and opens a file. TrueCrypt downloads only the part of the volume file that contains the file the user wants, and then decrypts it locally. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file over FTP, transferring encrypted data only. Is such a feature available?

• Create Chemistry Equations and Diagrams in Word

  - by Matthew Guay

  Microsoft Word is a great tool for formatting text, but what if you want to insert a chemistry formula or diagram?  Thanks to a new free add-in for Word, you can now insert high-quality chemistry formulas and diagrams directly from the Ribbon in Word. Microsoft’s new Education Labs has recently released the new Chemistry Add-in for Word 2007 and 2010.  This free download adds support for entering and editing chemistry symbols, diagrams, and formulas using the standard XML based Chemical Markup Language.  You can convert any chemical name, such as benzene, or formula, such as H2O, into a chemical diagram, standard name, or formula.  Whether you’re a professional chemist, just taking chemistry in school, or simply curious about the makeup of Citric Acid, this add-in is an exciting way to bring chemistry to your computer. This add-in works great on Word 2007 and 2010, including the 64 bit version of Word 2010.  Please note that the current version is still in beta, so only run it if you are comfortable running beta products. Getting Started Download the Chemistry add-in from Microsoft Education Labs (link below), and unzip the file.  Then, run the ChemistryAddinforWordBeta2.Setup.msi. It may inform you that you need to install the Visual Studio Tools for Office 3.0.  Simply click Yes to download these tools. This will open the download in your default browser.  Simply click run, or save and then run it when it is downloaded. Now, click next to install the Visual Studio Tools for Office as usual. When this is finished, run the ChemistryAddinforWordBeta2.Setup.msi again.  This time, you can easily install it with the default options. Once it’s finished installing, open Word to try out the Chemistry Add-in.  You will be asked if you want to install this customization, so click Install to enable it. Now you will have a new Chemistry tab in your Word ribbon.  Here’s the ribbon in Word 2010… And here it is in Word 2007.   Using the Chemistry Add-in It’s very easy to insert nice chemistry diagrams and formulas in Word with the Chemistry add-in.  You can quickly insert a premade diagram from the Chemistry Gallery: Or you can insert a formula from file.  Simply click “From File” and choose any Chemical Markup Language (.cml) formatted file to insert the chemical formula. You can also convert any chemical name to it’s chemical form.  Simply select the word, right-click, select “Convert to Chemistry Zone” and then click on its name. Now you can see the chemical form in the sidebar if you click the Chemistry Navigator button, and can choose to insert the diagram into the document.  Some chemicals will automatically convert to the diagram in the document, while others simply link to it in the sidebar.  Either way, you can display exactly what you want. You can also convert a chemical formula directly to it’s chemical diagram.  Here we entered H2O and converted it to Chemistry Zone: This directly converted it to the diagram directly in the document. You can click the Edit button on the top, and from there choose to either edit the 2D model of the chemical, or edit the labels. When you click Edit Labels, you may be asked which form you wish to display.  Here’s the options for potassium permanganate: You can then edit the names and formulas, and add or remove any you wish. If you choose to edit the chemical in 2D, you can even edit the individual atoms and change the chemical you’re diagramming.  This 2D editor has a lot of options, so you can get your chemical diagram to look just like you want. And, if you need any help or want to learn more about the Chemistry add-in and its features, simply click the help button in the Chemistry Ribbon.  This will open a Word document containing examples and explanations which can be helpful in mastering all the features of this add-in. All of this works perfectly, whether you’re running it in Word 2007 or 2010, 32 or 64 bit editions. Conclusion Whether you’re using chemistry formulas everyday or simply want to investigate a chemical makeup occasionally, this is a great way to do it with tools you already have on your computer.  It will also help make homework a bit easier if you’re struggling with it in high school or college.

• How do I disable MEDIUM and WEAK/LOW strength ciphers in Apache + mod_ssl?

  - by superwormy

  A PCI Compliance scan has suggested that we disable Apache's MEDIUM and LOW/WEAK strength ciphers for security. Can someone tell me how to disable these ciphers? Apache v2.2.14 mod_ssl v2.2.14 This is what they've told us: Synopsis : The remote service supports the use of medium strength SSL ciphers. Description : The remote host supports the use of SSL ciphers that offer medium strength encryption, which we currently regard as those with key lengths at least 56 bits and less than 112 bits. Solution: Reconfigure the affected application if possible to avoid use of medium strength ciphers. Risk Factor: Medium / CVSS Base Score : 5.0 (CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:N) [More] Synopsis : The remote service supports the use of weak SSL ciphers.

  This is the fourth post in my series about Personal Technology Tips and Tricks, and I knew exactly what I wanted to write about.  But at first I was conflicted.   Is online learning really a personal tip?  Is it really a trick that no one knows?  However, I have decided to stick with my original idea because online learning is everywhere.  It’s a trick that we can’t – and shouldn’t – overlook.  Here are ten of my ideas about how we should be taking advantage of online learning. 1) Get ahead in the work place.  We all know that a good way to become better at your job, and to become more competitive for promotions and raises.  Many people overlook online learning as a way to get job training, though, thinking it is a path for people still seeking their high school or college diplomas.  But take a look at what companies like Pluralsight offer, and you might be pleasantly surprised. 2) Flexibility.  Some of us remember the heady days of college with nostalgia, others remember it with loathing.  A lot of bad memories come from remembering the strict scheduling and deadlines of college.  But with online learning, the classes fit into your free time – you don’t have to schedule your life around classes.  Even better, there are usually no homework or test deadlines, only one final deadline where all work must be completed.  This allows students to work at their own pace – my next point. 3) Learn at your own pace.  One thing traditional classes suffer from is that they are highly structured.  If you work more quickly than the rest of the class, or especially if you work more slowly, traditional classes do not work for you.  Online courses let you move as quickly or as slowly as you find necessary. 4) Fill gaps in your knowledge.  I’m sure I am not the only one who has thought to myself “I would love to take a course on X, Y, or Z.”  The problem is that it can be very hard to find the perfect class that teaches exactly what you’re interested in, at a time and a price that’s right.  But online courses are far easier to tailor exactly to your tastes. 5) Fits into your schedule.  Even harder to find than a class you’re interested in is one that fits into your schedule.  If you hold down a job – even a part time job – you know it’s next to impossible to find class times that work for you.  Online classes can be taken anytime, anywhere.  On your lunch break, in your car, or in your pajamas at the end of the day. 6) Student centered.  Online learning has to stay competitive.  There are hundreds, even thousands of options for students, and every provider has to find a way to lure in students and provide them with a good education.  The best kind of online classes know that they need to provide great classes, flexible scheduling, and high quality to attract students – and the student benefit from this kind of attention. 7) You can save money.  The average cost for a college diploma in the US is over $20,000.  I don’t know about you, but that is not the kind of money I just have lying around for a rainy day.  Sometimes I think I’d love to go back to school, but not for that price tag.  Online courses are much, much more affordable.  And even better, you can pick and choose what courses you’d like to take, and avoid all the “electives” in college. 8) Get access to the best minds in the business.  One of the perks of being the best in your field is that you are one person who knows the most about something.  If students are lucky, you will choose to share that knowledge with them on a college campus.  For the hundreds of other students who don’t live in your area and don’t attend your school, they are out of luck.  But luckily for them, more and more online courses is attracting the best minds in the business, and if you enroll online, you can take advantage of these minds, too. 9) Save your time.  Getting a four year degree is a great decision, and I encourage everyone to pursue their Bachelor’s – and beyond.  But if you have already tried to go to school, or already have a degree but are thinking of switching fields, four years of your life is a long time to go back and redo things.  Getting your online degree will save you time by allowing you to work at your own pace, set your own schedule, and take only the classes you’re interested in. 10) Variety of degrees and programs.  If you’re not sure what you’re interested in, or if you only need a few classes here and there to finish a program, online classes are perfect for you.  You can pick and choose what you’d like, and sample a wide variety without spending too much money. I hope I’ve outlined for everyone just a few ways that they could benefit from online learning.  If you’re still unconvinced, just check out a few of my other articles that expand more on these topics.

• mysql master-master setup as a way to simply master-slave promotion

  - by Chris Go

  I'm trying to see if the following plan is viable. Goal here is to be able to do HA (uptime) and not necessarily for load -- writes are fine on one MySQL 5.5 server (with innodb) but not really possible when the database is down. Currently, I have a master-slave replication setup which works fine except it doesn't have automatic promotion (obviously). what I am planning on doing is setup master-master replication to possibly do this "automatic promotion" using Amazon Route 53 DNS Failover (Health checks). What I am trying to avoid is to NOT have to do the auto-increment trick because the "business folks" got used to the auto-incrementing PK as consecutive numbers (yeah, I know this is bad but data is from 2004). So, setup the master-master replication WITHOUT the auto-increment collision prevention bit. The primary master is db1.domain.com and secondary master is db2.domain.com In Amazon Route 53, setup DNS Failover record for db.domain.com - primary failover is db1.domain.com - with a TCP healthcheck on IP address port 3306 - secondary failover is db2.domain.com - with a TCP healthcheck on IP address port 3306 Most of the time (99%), unless tcp://db1.domain.com:3306 is dead, db1.domain.com will be served up on DNS hits to db.domain.com. In fact, hopefully this is 100%. The possible downsides of this is the loss of a primary key (collision) and I think I am OK with losing one order. We are a low data volume B2B business and can just call our client up if this occurs (like an order disappearing). Does this sound like a good plan? Then I will also run another slave replication on db1.domain.com as "master" to a slave-db1.domain.com -- not sure why, maybe for heavy SELECTs?

• most reliable linux terminal app / general procedures for process stability

  - by intuited

  I've been using konsole (KDE 4.2) for a while now but it crashed recently. Konsole is efficiently designed to use one instance for all of the windows for your entire X session. Extra-unfortunately, because of this ingenuity the crash brought down all the humpty-dumptys and their bashes and their bashes' applications and all the begattens' begattens all the way down to Jebodiah Springfield into one big flat nonexistent omelette. The fact that this app is capable of crashing under any circumstances is pretty disappointing. Although KDE 4.2 is not expected to be entirely stable -- and yes, I know, I should update my distro -- it's still a no-sell for me, since if at all possible, this sort of thing Shouldn't Happen to something that's likely to be a foundation for an entire working environment. Maybe this is arrogant and unrealistic, but if it's possible to have something more stable, I want it. So other than running under screen -- which is fun, nifty, and thus far flawless in its reliability, but which has some issues with not understanding certain keycodes -- I'm looking for ways to improve my environment's reliability. The most obvious strategy is to cast about for a more reliable console app. A standard featureset -- which to me includes tabbed windows, Unicode support, and a decent level of keyboard shortcut configuration -- is pretty much essential. I'm currently running gnome-terminal and roxterm, both of which have acceptable featuresets (pretty much identical, actually; I think rox is actually the superset), and neither of which have provided me with extensive, objective reliability data. Not that they were expected to. Other strategies are also welcome. Were I responding to this question I would perhaps suggest backgrounding critical tasks with & and/or disowning them so they don't come down with the global pandemic. And stuff like that.

• Ubuntu software stack to mimic Active Directory auth

  - by WickedGrey

  I'm going to have an Ubuntu 11.10 box in a customer's data center running a custom webapp. The customer will not have ssh access to the box, but will need authentication and authorization to access the webapp. The customer needs to have the option of either pointing the webapp at something that we've installed locally on the machine, or to use an Active Directory server that they have. I plan on using a standard "users belong to groups; groups have sets of permissions; the webapp requires certain permissions to respond" auth setup. What software stack can I install locally that will allow an easy switch to and from an Active Directory server, while keeping the configuration as simple as possible (both for me and the end customer)? I would like to use as much off-the-shelf software for this as possible; I do not want to be in the business of keeping user passwords secure. I could see handling the user/group/permission relationships myself if there is not a good out-of-the-box solution (but that seems highly unlikely). I will accept answers in the form of links to "here is what you need" pages, but not "here is what Kerberos does" unless that page also tells me if it's required for my use case (essentially, I know that AD can speak Kerberos, but I can't tell if I need it to, or if I can just use LDAP, or...).

• Preseeding Ubuntu partman recipe using LVM and RAID

  - by Swav

  I'm trying to preseed Ubuntu 12.04 server installation and created a recipe that would create RAID 1 on 2 drives and then partition that using LVM. Unfortunately partman complains when creating LVM volumes saying there no partitions in recipe that could be used with LVM (in console it complains about unusable recipe). The layout I'm after is RAID 1 on sdb and sdc (installing from USB stick so it takes sda) and then use LVM to create boot, root and swap. The odd thing is that if I change the mount point of boot_lv to home the recipe works fine (apart from mounting in wrong place), but when mounting at /boot it fails I know I could use separate /boot primary partition, but can anybody tell me why it fails. Recipe and relevant options below. ## Partitioning using RAID d-i partman-auto/disk string /dev/sdb /dev/sdc d-i partman-auto/method string raid d-i partman-lvm/device_remove_lvm boolean true d-i partman-md/device_remove_md boolean true #d-i partman-lvm/confirm boolean true d-i partman-auto-lvm/new_vg_name string main_vg d-i partman-auto/expert_recipe string \ multiraid :: \ 100 512 -1 raid \ $lvmignore{ } \ $primary{ } \ method{ raid } \ . \ 256 512 256 ext3 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext3 } \ mountpoint{ /boot } \ lv_name{ boot_lv } \ . \ 2000 5000 -1 ext4 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext4 } \ mountpoint{ / } \ lv_name{ root_lv } \ . \ 64 512 300% linux-swap \ $defaultignore{ } \ $lvmok{ } \ method{ swap } \ format{ } \ lv_name{ swap_lv } \ . d-i partman-auto-raid/recipe string \ 1 2 0 lvm - \ /dev/sdb1#/dev/sdc1 \ . d-i mdadm/boot_degraded boolean true #d-i partman-md/confirm boolean true #d-i partman-partitioning/confirm_write_new_label boolean true #d-i partman/choose_partition select Finish partitioning and write changes to disk #d-i partman/confirm boolean true #d-i partman-md/confirm_nooverwrite boolean true #d-i partman/confirm_nooverwrite boolean true EDIT: After a bit of googling I found below snippet of code from partman-auto-lvm, but I still don't understand why would they prevent that setup if it's possible to do manually and booting from boot partition on LVM is possible. # Make sure a boot partition isn't marked as lvmok if echo "$scheme" | grep lvmok | grep -q "[[:space:]]/boot[[:space:]]"; then bail_out unusable_recipe fi

• Windows or Linux for VPN-VPN Bridge

  - by James

  I have the following network layout: Network1 ----VPN1-----Network2----VPN2----Network3 I can administer everything in Network1 only and my goal is to get to a box on Network3. I've been told by the admins of Network2 that it's not possible for them to route traffic from Network1 to Network3. I've finally been authorised to host a box in Network2 and I'm hoping with this I can set something up to resolve the issue. My question is should I set this up as a Windows or a Linux box. My initial thought was to use iptables to reroute requests but with my lack of experience with Windows Server (used for something or other in Network2) I'm not sure if this will work. My head's full of questions like: - can I get an ip without logging in to a windows domain? - if I do get an ip, do Windows Servers manage routing through the VPN? - can I make a linux box authenticate with Windows Server to log on to the domain? - would it just be easier to set up a windows box? - is it possible to configure a windows box to do routing from Network1 to Network3? Has anyone done anything like this before? Had experience managing Windows Server? Authenticated (or not as the case may be) to a Windows domain? I'd really appreciate your advice. It might be worth mentioning that the overall objective is to establish a telnet connection from a box on Network1 to a box on Network3.

• Clone virtual machine with Server 2008 R2 and Hyper-V?

  - by bwerks

  Hi all, I've recently just started working with Hyper-V, and so far it's quite nice. However, I've been running into problems with what seems like it should be the most basic of workflows. I've set up a baseline Server 2008 R2 configuration, and exported it with the intention of using the export for cloning. I entered "C:\Exports\" as the export folder. However, I run into problems when I try to import the image. From the Hyper-V manager, I select "Import Virtual Machine" and in the resulting window I entered "C:\Exports\BuildServer\" as the folder, set the radial to "Copy the virtual machine (create a new unique ID)" and checked the checkbox for "Duplicate all files so the same virtual machine can be imported again." Doing so results in the following error: "Import failed. Import task failed to copy file from 'H:\Exports\BuildServer\Virtual Hard Disks\BuildServer.vhd' to 'C:\Hyper-V\Virtual Hard Disks\BuildServer.vhd': The file exists. (0x80070050)" Have I somehow messed something up in configuration? Or is this a known thing? I've read it should be possible to clone VMs by copying them in the filesystem but I'd prefer to keep things in the management Ui if possible.

• GNU screen, how to get current sessionname programmably

  - by Jimm Chen

  [ This can be considered step 2 of my previous question Is it possible to change GNU screen session name after created? ] Actually, I'd like to write a script that can display current screen session name and change current session name. For example: sren armcross It will change the session name to armcross (ARM gcc cross compiler) and output something like: screen session name changed from '25278.pts-15.linux-ic37' to 'armcross' So, the key question now is how to get current session name. Not only for display the old session name, but according to Is it possible to change GNU screen session name after created? , I have to know it(pass to -d -r) before I can change it to something else. Can we use $STY for current session name? No. $STY will not change after you have changed the session name to a user-defined one. However, for command screen -d -r <oldsessname> -X sessionname armcross should be the user-defined name(if ever defined) instead of $STY, otherwise, screen spouts error "No screen session found." Maybe, there is a verbose way, use screen -list to list all sessions(user-defined name listed), then, match the pid part from $STY against those listed sessions and we will find current session's user-defined name. It should not be so verbose for such a straightforward question. Don't you think so? The -d -D and -r -R options seems to expose too much implementation detail to screen's user. It seems, to rename a session, you have to detach it, then do the rename, then reattach it. Right? My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06 Thank you.

• How to remove strict RSA key checking in SSH and what's the problem here?

  - by setatakahashi

  I have a Linux server that whenever I connect it shows me the message that changed the SSH host key: $ ssh root@host1 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 93:a2:1b:1c:5f:3e:68:47:bf:79:56:52:f0:ec:03:6b. Please contact your system administrator. Add correct host key in /home/emerson/.ssh/known_hosts to get rid of this message. Offending key in /home/emerson/.ssh/known_hosts:377 RSA host key for host1 has changed and you have requested strict checking. Host key verification failed. It keeps me for a very few seconds logged in and then it closes the connection. host1:~/.ssh # Read from remote host host1: Connection reset by peer Connection to host1 closed. Does anyone know what's happening and what I could do to solve this problem?

• ESXi Server with 12 physical cores maxed out with only 8 cores assigned in virtual machines

  - by Sam

  I have an ESXi 5 server running on a 2-processor, 12-core system with hyperthreading enabled. So: 12 physical cores, 24 logical ones. On this server are 4 Windows 7 VMs, each configured for 2 processors, each running VMware Tools. Looking at my stats in vSphere, my "core utilization" is constantly maxed out. Yes, these machines are working hard, but only 8 cores have been allocated. How is this possible? Should I look into reducing the processor count per machine as in this post: VMware ESX server? I checked to ensure that hardware virtualization is enabled in the BIOS of the machine (a DELL R410). I've also started reading up on configuration, but being a newbie there's a lot of material to catch up on. It also seems I should only bother with advanced settings and pools if I'm really pushing the load, and I don't think that I should be pushing it with so few VMs. I suspect that I have some basic, incorrect configuration setting, but it's also possible that I have some giant misconceptions about virtualization. Any pointers? EDIT: Given the responses I've gotten so far, it seems that this is a measurement problem and not a configuration problem, making this less critical. Perhaps the real question is: How does the core utilization of the server reach a higher percentage than all individual cores' core utilization, and given that this possibility makes the metric useless for overall server load, what is the best global metric for measuring CPU load on hyper-threaded systems?

• How do multiple displays work on a AMD 785G / ATI HD 4200 motherboard?

  - by aireq

  I just ordered a ASUS M4A785TD-V EVO which has the AMD 785G chipset and HD4200 integrated graphic. The board has VGA, DVI, and HDMI outputs. I'm wondering how many outputs I can run at once, and from what connectors? My guess is that I can only use the VGA, and either the DVI or the HDMI in a dual setup. But not the HDMI and the DVI at the same time. Is this correct? If I have devices plugged into both the HDMI and the DVI ports is there a way to choose between which port I want to use? I have a dual 19" monitor setup, as well as a LCD TV. I'd like to run the VGA and the DVI into my two monitors, and then the HDMI to my TV. Then when I want to watch something on the TV I'd like to be able to switch over from the DVI to the HDMI. Is this possible with out crawling under my desk and unplugging/plugging things in? Update I found the following in the manual off ASUS's website, which confirms my original suspicion that HDMI and DVI can't be used at the same time. But I'd still like to know if it's possible through software to switch between using the HDMI and DVI.

  I accidentally overwrote system.dbf in /usr/lib/oracle/xe/oradata/XE/system.dbf Well I did not actually do it accidentally, however I overwrote it because of other failures in the database.

• So Close: How to get this SSH login working (.bashrc)

  - by This_Is_Fun

  Objective: SSH login ( + eliminate warning message) / run 2 commands / stay logged in: EDIT: Oops, I made a mistake (see below): This code does ~95% of what I wanted to do # .bashrc # Run two commands and stay logged in to new server. alias gr='ssh -t -p 5xx4x [email protected] 2> /dev/null "cd /var; ls; /bin/bash -i"' Now, after successful login / verify user logged in = root pts/0 2011-01-30 22:09 Try to 'logout' = bash: logout: not login shell: use `exit' I seem to have full root access w/o being logged into the shell? (The " /bin/bash -i " was added to 'Stay logged in' but doesn't work quite as expected) FYI: The question is "How to get this SSH login working" & it is mostly solved, sorry I made a mess... ... .. . Original Question Here: # .bashrc # Run two commands and stay logged in to new server. alias gr='ssh -t -p 5xx4x [email protected] "cd /var; ls; /bin/bash -i"' # (hack) Hide "map back to the address - POSSIBLE BREAK-IN ATTEMPT!" message. alias gr='ssh -p 5xx4x [email protected] 2> /dev/null' Both examples 'work' as shown; When I try to add the ' 2 /dev/null ' to the first example, then the whole thing breaks. I'm out of time trying to solve the warning message other ways, so is it possible to combine both examples to make example #1 work w/o the warning message? Thank you. ps. If you also know a proper way to kill the login warning message, please do tell (the 'standard' "edit host file" advice isn't working for me)

• Run Explorer in SYSTEM account on Windows Vista or 7 using Sysinternal’s psexec tool?

  - by Rob

  Has anyone been successful at launching an instance of Windows Explorer in the SYSTEM account on Windows Vista or 7? It is possible to do this on XP, but I haven't been able to get it to completely work in Vista or 7. Trying to launch Explorer as SYSTEM into session 1 (my user session) results in Explorer exiting immediately and returning an error code of 1. I can launch Explorer as SYSTEM into session 0 with the following command: psexec -i 0 -s explorer That will create an instance of explorer running as SYSTEM with a taskbar and start menu on the hidden session 0 desktop, but won't let you open a file browser window. If you switch to the hidden session 0 desktop and try to open an Explorer window from there to browse files, the following error message appears: "The server process could not be started because the configured identity is incorrect. Check the username and password." I have set the following registry key to 1 for my user account and the SYSTEM account: \Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\SeparateProcess There has got to be a way to make this work? If it is not possible, can anyone explain why? -Rob

• Mac Management and Security

  - by Bart Silverstrim

  I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

• How to configure Farsun USB barcode scanner to not auto-trigger

  - by David Grayson

  At my company we have several USB barcode scanners. I'm not sure exactly what model they are, but I think they are the FG9800 from Farsun because that's what they look like on the exterior. They came with a programming manual that is very similar to this document from the Farsun website. When I scan the "Output Firmware Version" barcode, my scanner types the following into the computer: Farsun V2.00 2011-01-01 Is it possible to configure these scanners so they only read barcodes in response to the trigger button being pressed? I don't want them to automatically read barcodes. Additionally, I want this setting to be remembered while the scanner is turned off. Since this scanner only has a USB port, the only way to configure it that I know of is to scan bar codes from the manual (or make your own). I have tried scanning the configuration bar codes for Single Scan (013300), Single Scan No Trigger (013301), and Laser/CCD Timeout - 5 Seconds (0134005) from this document. Sometimes (but not often) this puts the scanner in to the right mode, where it only scans when the button is pressed. Unfortunately, the scanner seems to always leave this mode when it is power cycled. I have also scanned the "Reset Configuration To Defaults" barcode (0B) many times. We have three different scanners like this and I have not been able to successfully configure any of them. If the things I want are not possible with these Farsun-based scanners, is there some other scanner we can use?

• Not so long ago in a city not so far away by Carlos Martin

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 This is the story of how the EMEA Presales Center turned an Oracle intern into a trusted technology advisor for both Oracle’s Sales and customers. It was the summer of 2011 when I was finishing my Computer Engineering studies as well as my internship at Oracle when I was offered what could possibly be THE dream job for any young European Computer Engineer. Apart from that, it also seemed like the role was particularly tailored to me as I could leverage almost everything I learned at University and during the internship. And all of it in one of the best cities to live in, not only from my home country but arguably from Europe: Malaga! A day at EPC As part of the EPC Technology pillar, and later on completely focused on WebCenter, there was no way to describe a normal day on the job as each day had something unique. Some days I was researching documentation in order to elaborate accurate answers for a customer’s question within a Request for Information or Proposal (RFI/RFP), other days I was doing heavy programming in order to bring a Proof of Concept (PoC) for a customer to life and last not but least, some days I presented to the customer via webconference the demo I built for them the past weeks. So as you can see, the role has research, development and presentation, could you ask for more? Well, don’t worry because there IS more! Internationality As the organization’s name suggests, EMEA Presales Center, it is the Center of Presales within Europe, Middle East and Africa so I got the chance to work with great professionals from all this regions, expanding my network and learning things from one country to apply them to others. In addition to that, the teams based in the Malaga office are comprised of many young professionals hailing mainly from Western and Central European countries (although there are a couple of exceptions!) with very different backgrounds and personalities which guaranteed many laughs and stories during lunch or coffee breaks (or even while working on projects!). Furthermore, having EPC offices in Bucharest and Bangalore and thanks to today’s tele-presence technologies, I was working every day with people from India or Romania as if they were sitting right next to me and the bonding with them got stronger day by day. Career development Apart from the research and self-study I’ve earlier mentioned, one of the EPC’s Key Performance Indicators (KPI) is that 15% of your time is spent on training so you get lots and lots of trainings in order to develop both your technical product knowledge and your presentation, negotiation and other soft skills. Sometimes the training is via webcast, sometimes the trainer comes to the office and sometimes, the best times, you get to travel abroad in order to attend a training, which also helps you to further develop your network by meeting face to face with many people you only know from some email or instant messaging interaction. And as the months go by, your skills improving at a very fast pace, your relevance increasing with each new project you successfully deliver, it’s only a matter of time (and a bit of self-promoting!) that you get the attention of the manager of a more senior team and are offered the opportunity to take a new step in your professional career. For me it took 2 years to move to my current position, Technology Sales Consultant at the Oracle Direct organization. During those 2 years I had built a good relationship with the Oracle Direct Spanish sales and sales managers, who are also based in the Malaga office. I supported their former Sales Consultant in a couple of presentations and demos and were very happy with my overall performance and attitude so even before the position got eventually vacant, I got a heads-up from then in advance that their current Sales Consultant was going to move to a different position. To me it felt like a natural step, same as when I joined EPC, I had at least a 50% of the “homework” already done but wanted to experience that extra 50% to add new product and soft skills to my arsenal. The rest is history, I’ve been in the role for more than half a year as I’m writing this, achieved already some important wins, gained a lot of trust and confidence in front of customers and broadened my view of Oracle’s Fusion Middleware portfolio. I look back at the 2 years I spent in EPC and think: “boy, I’d recommend that experience to absolutely anyone with the slightest interest in IT, there are so many different things you can do as there are different kind of roles you can end up taking thanks to the experience gained at EPC” /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• Routing Apache TracEnv

  - by fampinheiro

  Hello, i have a situation with many trac instances. They all have the same structure in the filesystem. PATH/trac1 PATH/trac2 PATH/trac3 i have this configuration <Location /trac/trac1> SetHandler mod_python PythonInterpreter main_interpreter PythonHandler trac.web.modpython_frontend PythonOption TracEnv PATH/trac1 PythonOption TracUriRoot /trac/trac1 PythonOption PYTHON_EGG_CACHE PATH/eggs/ </Location> <Location /trac/trac2> SetHandler mod_python PythonInterpreter main_interpreter PythonHandler trac.web.modpython_frontend PythonOption TracEnv PATH/trac2 PythonOption TracUriRoot /trac/trac2 PythonOption PYTHON_EGG_CACHE PATH/eggs/ </Location> <Location /trac/trac3> SetHandler mod_python PythonInterpreter main_interpreter PythonHandler trac.web.modpython_frontend PythonOption TracEnv PATH/trac3 PythonOption TracUriRoot /trac/trac3 PythonOption PYTHON_EGG_CACHE PATH/eggs/ </Location> i wonder if it's possible to do something like (TracEnvParentDir is not an option) <Location /trac/{ENV}> SetHandler mod_python PythonInterpreter main_interpreter PythonHandler trac.web.modpython_frontend PythonOption TracEnv PATH/{ENV} PythonOption TracUriRoot /trac/{ENV} PythonOption PYTHON_EGG_CACHE PATH/eggs/ </Location> Thank you for your time. EDIT: TracEnvParentDir is not an option because my structure is the following +---projs +---trac1 ¦ +---public [instance] ¦ +---t1 ¦ ¦ +---common [instance] ¦ ¦ +---g1 [instance] ¦ ¦ +---g2 [instance] ¦ ¦ +---g3 [instance] ¦ ¦ +---g4 [instance] ¦ ¦ +---g5 [instance] ¦ +---t2 ¦ ¦ +---common [instance] ¦ ¦ +---g1 [instance] ¦ ¦ +---g2 [instance] ¦ ¦ +---g3 [instance] ¦ ¦ +---g4 [instance] ¦ ¦ +---g5 [instance] ¦ +---t3 ¦ +---common [instance] ¦ +---g1 [instance] ¦ +---g2 [instance] ¦ +---g3 [instance] ¦ +---g4 [instance] ¦ +---g5 [instance] ¦ +---trac2 +---public [instance] +---t1 ¦ +---common [instance] ¦ +---g1 [instance] ¦ +---g2 [instance] ¦ +---g3 [instance] ¦ +---g4 [instance] ¦ +---g5 [instance] +---t2 ¦ +---common [instance] ¦ +---g1 [instance] ¦ +---g2 [instance] ¦ +---g3 [instance] ¦ +---g4 [instance] ¦ +---g5 [instance] +---t3 +---common [instance] +---g1 [instance] +---g2 [instance] +---g3 [instance] +---g4 [instance] +---g5 [instance] I use the TracEnvParentDir on t1, t2 and t3 and TracEnv on trac1/public and trac2/public I wonder if it's possible to define a part of the url variable.

• How to configure amavisd-new for only scanning on particular senders/servers?

  - by mailq

  I'd like to know how to configure amavisd-new to only scan for Spam on particular clients (IPs, CIDRs or hostnames) or alternatively sender's email domain. I know that it is possible to do it on a recipient's mail address but not on how to do it for the sender's mail address. It is even possible to do it on a recipient's IP address with policy banks. But my approach should be to be independent of recipient and only relay on the sender. What I want to accomplish is to only scan mails originating from Yahoo, Google, Hotmail and the other big senders. So it is easier to configure which senders should be observed than the ones that shouldn't. I known that it is easier to achieve on the MTA side, but that is not part of the question because I already go a solution on the MTA side. I want to do it on amavisd-new. And it doesn't help to know how to put senders on a whitelist, as this still means that the mail goes through all the scanning but then gets a high negative score. The mail shouldn't be scanned at all unless sent by the big players. So which parameters in amavisd-new is the right one to enable scanning for particular senders and only for these?
