• Patch Set 11.2.0.2 for Win32 and Win64 now available

  - by Mike Dietrich

  Oracle Database Patch Set 11.2.0.2 for Windows (Patch: 10098816) is now available for download from support.oracle.com: Oracle Database 11.2.0.2 Patch Set for Windows 32bit Oracle Database 11.2.0.2 Patch Set for Windows 64bit Please keep in mind: It's a full install - you don't have to download 11.2.0.1 first, you can start right with 11.2.0.2 You'll get it just from support.oracle.com - no download from OTN or eDelivery as this is a patch set Installation will be done by default into a separate %ORACLE_HOME% .- and this is our strong recommendation. If you'd like to install into your existing 11.2.0.1 %ORACLE_HOME% then you'll have to detach your 11.2.0.1 home from the OUI inventory first (runInstaller -detachHome ORACLE_HOME=c:\orahomes\11.2.0), save the contents of ?\network\admin and ?\database, clean up, install 11.2.0.2 and copy the saved network\admin and \database content back. Btw, Oracle Database Patch Set 10.2.0.5 for HP-UX - Patch:8202632 is available for download as well since today.

• How do I set a postgresql password in pgpass.conf for the Administrator account on Windows Server 2008?

  - by brad

  I have a pgpass.conf file that works well for my default user. It is in C:/Users/myuser/AppData/Roaming/postgresql/pgpass.conf. It reads like so; localhost:5432:*:postgres:password1 I have a process that runs under the Administrator account. When I run whoami under this process I get nt authority/system. I want to be able to access the database from this process but it gets stuck because it needs a password. I have tried putting the above pgpass.conf into C:/Users/Administrator/AppData/postgresql/pgpass.conf and C:/Users/Administrator/AppData/Roaming/postgresql/pgpass.conf but it does not work. Is this the correct place for this file? Am I even able to do this as the Administrator. Unfortunately I cannot change the user that this process runs under.

• Fail rate of EBS snapshots and AMIs?

  - by user784637

  According to Amazon the fail rate of EBS volumes is: As an example, volumes that operate with 20 GB or less of modified data since their most recent Amazon EBS snapshot can expect an annual failure rate (AFR) of between 0.1% – 0.5%, where failure refers to a complete loss of the volume http://aws.amazon.com/ebs/ However, I was curious to know the fail rate of EBS snapshots and private AMIs that a system admin would take. Since the EBS snapshots and AMIs are stored in Amazon s3, is it safe to assume that the likelihood you cannot rollback to a previous snapshot or AMI the same likelihood that a file gets lost in s3? Amazon S3’s standard storage is: ... Designed to provide 99.999999999% durability and 99.99% availability of objects over a given year. http://aws.amazon.com/s3/

• MS SQL Server not running on Win7

  - by Anas

  I have installed available all components of "MS_SQL_05" as give named instance on Win-7. I had a default instance running of MSSQL08. While Installing MSSQL05 Instance I choose to use windows authentication. But now I got a problem and my database engine is not running, actually no components are working except I am just able to login to Integration service. I think there is some Username issue, coz It using UsrNm :'Anas-PC\Anas' which seems incorrect. Here below is the detail =================================== Cannot connect to ANAS-PC\MS_SQL_05. =================================== Login failed for user 'Anas-PC\Anas'.

• Recovering Ubuntu 9.10 /Windows 7 dual boot with Wubi

  - by user56110

  I had installed Ubuntu 9.10 /Windows 7 dual boot with Wubi. I had no issues for about 9 months, and then after having to do a force reboot after ubuntu got hunng, and never goes past boot-up. On boot up, and selecting ubuntu, I get this error message: One or more of the mounts listed in /etc/fstab cannot yet be mounted: /: waiting for /dev/loop0 /tmp: waiting for (null) Press ESC to enter a recovery shell When I enter the recovery shell, I get this error message: General error mounting filesystem A maintainance shell will be started The maintenace shell does start- and I am able to access files. However, X-server does not work, so gedit, and similar applications does not work. I have done chkdsk on Windows, and this didnt solve nmy problem. From what I have been reading online,I have seen quite a few posts advising against wubi ubuntu installation, and generally to the effect that 'do a clean install' I found that the person on this thread has faced an identical issue, but he had to do a re-install http://ubuntuforums.org/archive/index.php/t-1051277.html Can I make my ubuntu box work right, as it was before? :-)

• How do I resolve a plugin conflict in Eclipse?

  - by Jason Thompson

  I'd like to upgrade my Helios installation of Eclipse to Indigo. When I do, I get the following message: Cannot complete the install because of a conflicting dependency. Software being installed: Eclipse IDE for Java EE Developers 1.4.2.20120213-0813 (epp.package.jee 1.4.2.20120213-0813) Software currently installed: Oracle GlassFish Server Tools 1.6.1.201009290929 (oracle.eclipse.tools.helios.glassfish.feature.group 1.6.1.201009290929) So my first thought was to simply uninstall GlassFish. For the life of me, I can't figure out how and where to go to do this. I went to Help-About Eclipse...-Installation Details. The only place that it looks like I can uninstall stuff is in the "Installed Software" tab. I do not see the Oracle Glassfish package anywhere. If I go to "Feature" or "Plug-ins", I can find it just fine, but there is no option to uninstall. So my next thought was to upgrade Glassfish. So I put the indigo repo in there, but I still get the same message when trying to update. Any ideas?

• 8 Things You Didn’t Know You Could Do In Windows 7's Task Manager

  - by Chris Hoffman

  The Windows Task Manager is often used for troubleshooting – perhaps closing an application that isn’t working properly or monitoring system resource usage. However, there’s a lot more you can do with Windows 7’s Task Manager. To quickly open the Task Manager, right-click your taskbar and select Start Task Manager. You can also press Ctrl+Shift+Esc to quickly launch the Task Manager with a keyboard shortcut. Windows 8 may have a great new task manager, but Windows 7’s is still useful.

• Install ubuntu-11.10-desktop-amd64 with Logitech diNovo Edge

  - by MyGGaN

  I know there are problems (and have been for quite some time) with the diNovo Edge keyboard. The solution could be found easily and often you can use the on-screen keyboard to fix it. Now I'm installing Ubuntu from scratch and the only keyboard I have is my diNovo, am I screwed? You are able to get to System Config during the install process and from there to Accessibility menu where you usually can start the on-screen keyboard. This doesn't work, no keyboard in sight... What if I can do some ninja copy-paste with the mouse?? Nope, no pasting allowed in the feilds: username, password, etc. Is there a chance I can fix this somehow within the .iso file before I create the bootable USB drive I use to install from? Or do I have to buy a keyboard to be able to install Ubuntu?

• RUIN: A Post-Apocalyptic Short Animation [Video]

  - by Jason Fitzpatrick

  If your coffee has failed to perk you up this morning, this action-packed post-apocalyptic animation–a trailer for a work-in-progress CGI movie–most certainly will. Courtesy of Oddball Animation, RUIN is a polished bit of animation that could easily stand alone as a short film.  The studio is in the process of shopping it around to extend it into a full length movie which, if it looks as good as it does in the short form, will be worth the price of admission.

• Read only file system

  - by Jack Moon

  I'm running Ubuntu 12.10, Upon opening any shell I get the following error: /home/jack/.rbenv/libexec/rbenv-init: line 87: cannot create temp file for here-document: Read-only file system I realised this wasn't simply a rbenv issue, as any file I try to write to returns an error saying the system is Read-only. I don't know how else to describe my problem, each time I boot up the system goes through a disk check, where it supposedly fixes several errors in my disk. Here is my /etc/fstab # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=1cc4b2ab-a984-4516-ac25-6d64f5050244 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda5 during installation UUID=4e0dfeae-701a-43ce-b5c6-65f15ab3d8e3 none swap sw 0 0 The entire file system is read-only.

• Exchange Public Folders in Snow Leopard Mail.app

  - by Paul

  I am using Mail.app (running snow leopard) to connect to my email account on my school's Exchange 2007 server. I get my Inbox just fine, and iCal connects to my Outlook Calendar just fine, but I cannot seem to get any of the Exchange Public Folders that I can automatically see when I am using Outlook on a Windows box. The Account Type is shown as "Exchange 2007" I did not have any luck Googling this problem, in fact most of the results I saw were dealing with the opposite problem: Remove MS Exchange Public Folders I am aware that my question is a duplicate of this: http://superuser.com/questions/103115/apple-mail-app-all-exchange-folders-not-visible but since that question did not get any responses, I am reposting.

• How to set selinux?

  I installed selinux first, I set SELINUX=enforcing instead of its original value, SELINUX=permissive in /etc/selinux/config, then I reboot my computer. I waited for some time, but it stopped, I rebooted again and it can not go into the system anymore so I restored the setting. I tried to run seinfo command in a terminal, but it output some errors below: ERROR: policydb version 26 does not match my version range 15-24 ERROR: Unable to open policy /etc/selinux/ubuntu/policy/policy.26. ERROR: Input/output error It seems that there is a little difference on how to start up selinux between CentOS and Ubuntu, can you help me configure selinux in Ubuntu?

• Configure FastCGI for Python

  - by Rob

  I have nginx running on a VM and I want to run a Trac site. I need to run a python FastCGI server, but I cannot tell which is the server to use. I have found the following: <a href="http://redmine.lighttpd.net/projects/spawn-fcgi">Lighttpd spawn-fcgi</a> But this seems to require that you compile lighttpd just to get the fcgi server, which is weird. <a href="http://svn.saddi.com/py-lib/trunk/fcgi.py">fcgi.py</a> But this one seems to be depreciated. At the very least it is poorly documented. <a href="http://trac.saddi.com/flup">flup</a> This one comes with dependencies on ubuntu (python-cheetah{a} python-mysqldb{a} python-webpy{a}) that seem unnecessary. Also poorly documented. Are their any recent guides for setting this up. Trac's own FastCGI setup page seems to miss some steps.

• How do I remove a repository of yum

  - by sunil

  When I search for a package in yum(centos 6), it tries to search in a repro named 'c6-media' And it gives a bunch of errors as follows file:///media/CentOS/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/CentOS/repodata/repomd.xml Trying other mirror. file:///media/cdrecorder/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrecorder/repodata/repomd.xml Trying other mirror. file:///media/cdrom/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrom/repodata/repomd.xml Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: c6-media. Please verify its path and try again Obviously the error seems to say that yum is trying to search for the CD/DVD which installed the OS. I do not have it now. All I want to do now is to delete this repository from yum. I went to the package manager graphical tool and removed this from the sources. Seems yum and the graphical tool do not use the same config. This is just my guess.

• Performance Optimization &ndash; It Is Faster When You Can Measure It

  - by Alois Kraus

  Performance optimization in bigger systems is hard because the measured numbers can vary greatly depending on the measurement method of your choice. To measure execution timing of specific methods in your application you usually use Time Measurement Method Potential Pitfalls Stopwatch Most accurate method on recent processors. Internally it uses the RDTSC instruction. Since the counter is processor specific you can get greatly different values when your thread is scheduled to another core or the core goes into a power saving mode. But things do change luckily: Intel's Designer's vol3b, section 16.11.1 "16.11.1 Invariant TSC The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC. Processor's support for invariant TSC is indicated by CPUID.80000007H:EDX[8]. The invariant TSC will run at a constant rate in all ACPI P-, C-. and T-states. This is the architectural behavior moving forward. On processors with invariant TSC support, the OS may use the TSC for wall clock timer services (instead of ACPI or HPET timers). TSC reads are much more efficient and do not incur the overhead associated with a ring transition or access to a platform resource." DateTime.Now Good but it has only a resolution of 16ms which can be not enough if you want more accuracy.   Reporting Method Potential Pitfalls Console.WriteLine Ok if not called too often. Debug.Print Are you really measuring performance with Debug Builds? Shame on you. Trace.WriteLine Better but you need to plug in some good output listener like a trace file. But be aware that the first time you call this method it will read your app.config and deserialize your system.diagnostics section which does also take time.   In general it is a good idea to use some tracing library which does measure the timing for you and you only need to decorate some methods with tracing so you can later verify if something has changed for the better or worse. In my previous article I did compare measuring performance with quantum mechanics. This analogy does work surprising well. When you measure a quantum system there is a lower limit how accurately you can measure something. The Heisenberg uncertainty relation does tell us that you cannot measure of a quantum system the impulse and location of a particle at the same time with infinite accuracy. For programmers the two variables are execution time and memory allocations. If you try to measure the timings of all methods in your application you will need to store them somewhere. The fastest storage space besides the CPU cache is the memory. But if your timing values do consume all available memory there is no memory left for the actual application to run. On the other hand if you try to record all memory allocations of your application you will also need to store the data somewhere. This will cost you memory and execution time. These constraints are always there and regardless how good the marketing of tool vendors for performance and memory profilers are: Any measurement will disturb the system in a non predictable way. Commercial tool vendors will tell you they do calculate this overhead and subtract it from the measured values to give you the most accurate values but in reality it is not entirely true. After falling into the trap to trust the profiler timings several times I have got into the habit to Measure with a profiler to get an idea where potential bottlenecks are. Measure again with tracing only the specific methods to check if this method is really worth optimizing. Optimize it Measure again. Be surprised that your optimization has made things worse. Think harder Implement something that really works. Measure again Finished! - Or look for the next bottleneck. Recently I have looked into issues with serialization performance. For serialization DataContractSerializer was used and I was not sure if XML is really the most optimal wire format. After looking around I have found protobuf-net which uses Googles Protocol Buffer format which is a compact binary serialization format. What is good for Google should be good for us. A small sample app to check out performance was a matter of minutes: using ProtoBuf; using System; using System.Diagnostics; using System.IO; using System.Reflection; using System.Runtime.Serialization; [DataContract, Serializable] class Data { [DataMember(Order=1)] public int IntValue { get; set; } [DataMember(Order = 2)] public string StringValue { get; set; } [DataMember(Order = 3)] public bool IsActivated { get; set; } [DataMember(Order = 4)] public BindingFlags Flags { get; set; } } class Program { static MemoryStream _Stream = new MemoryStream(); static MemoryStream Stream { get { _Stream.Position = 0; _Stream.SetLength(0); return _Stream; } } static void Main(string[] args) { DataContractSerializer ser = new DataContractSerializer(typeof(Data)); Data data = new Data { IntValue = 100, IsActivated = true, StringValue = "Hi this is a small string value to check if serialization does work as expected" }; var sw = Stopwatch.StartNew(); int Runs = 1000 * 1000; for (int i = 0; i < Runs; i++) { //ser.WriteObject(Stream, data); Serializer.Serialize<Data>(Stream, data); } sw.Stop(); Console.WriteLine("Did take {0:N0}ms for {1:N0} objects", sw.Elapsed.TotalMilliseconds, Runs); Console.ReadLine(); } } The results are indeed promising: Serializer Time in ms N objects protobuf-net   807 1000000 DataContract 4402 1000000 Nearly a factor 5 faster and a much more compact wire format. Lets use it! After switching over to protbuf-net the transfered wire data has dropped by a factor two (good) and the performance has worsened by nearly a factor two. How is that possible? We have measured it? Protobuf-net is much faster! As it turns out protobuf-net is faster but it has a cost: For the first time a type is de/serialized it does use some very smart code-gen which does not come for free. Lets try to measure this one by setting of our performance test app the Runs value not to one million but to 1. Serializer Time in ms N objects protobuf-net 85 1 DataContract 24 1 The code-gen overhead is significant and can take up to 200ms for more complex types. The break even point where the code-gen cost is amortized by its faster serialization performance is (assuming small objects) somewhere between 20.000-40.000 serialized objects. As it turned out my specific scenario involved about 100 types and 1000 serializations in total. That explains why the good old DataContractSerializer is not so easy to take out of business. The final approach I ended up was to reduce the number of types and to serialize primitive types via BinaryWriter directly which turned out to be a pretty good alternative. It sounded good until I measured again and found that my optimizations so far do not help much. After looking more deeper at the profiling data I did found that one of the 1000 calls did take 50% of the time. So how do I find out which call it was? Normal profilers do fail short at this discipline. A (totally undeserved) relatively unknown profiler is SpeedTrace which does unlike normal profilers create traces of your applications by instrumenting your IL code at runtime. This way you can look at the full call stack of the one slow serializer call to find out if this stack was something special. Unfortunately the call stack showed nothing special. But luckily I have my own tracing as well and I could see that the slow serializer call did happen during the serialization of a bool value. When you encounter after much analysis something unreasonable you cannot explain it then the chances are good that your thread was suspended by the garbage collector. If there is a problem with excessive GCs remains to be investigated but so far the serialization performance seems to be mostly ok.  When you do profile a complex system with many interconnected processes you can never be sure that the timings you just did measure are accurate at all. Some process might be hitting the disc slowing things down for all other processes for some seconds as well. There is a big difference between warm and cold startup. If you restart all processes you can basically forget the first run because of the OS disc cache, JIT and GCs make the measured timings very flexible. When you are in need of a random number generator you should measure cold startup times of a sufficiently complex system. After the first run you can try again getting different and much lower numbers. Now try again at least two times to get some feeling how stable the numbers are. Oh and try to do the same thing the next day. It might be that the bottleneck you found yesterday is gone today. Thanks to GC and other random stuff it can become pretty hard to find stuff worth optimizing if no big bottlenecks except bloatloads of code are left anymore. When I have found a spot worth optimizing I do make the code changes and do measure again to check if something has changed. If it has got slower and I am certain that my change should have made it faster I can blame the GC again. The thing is that if you optimize stuff and you allocate less objects the GC times will shift to some other location. If you are unlucky it will make your faster working code slower because you see now GCs at times where none were before. This is where the stuff does get really tricky. A safe escape hatch is to create a repro of the slow code in an isolated application so you can change things fast in a reliable manner. Then the normal profilers do also start working again. As Vance Morrison does point out it is much more complex to profile a system against the wall clock compared to optimize for CPU time. The reason is that for wall clock time analysis you need to understand how your system does work and which threads (if you have not one but perhaps 20) are causing a visible delay to the end user and which threads can wait a long time without affecting the user experience at all. Next time: Commercial profiler shootout.

• Mathematica 8 crashes Ubuntu 13.10

  - by Georgy Ivanov

  I have Mathematica 8 installed on my Ubuntu laptop since 2011. I updated Ubuntu several times, and experienced no problems with Mathematica. It also worked smoothly after I updated Ubuntu to 13.10 (it worked for sure for a week after update). When I tried to start Mathematica today by executing a .sh-file, the screen went black, I was logged out from the session and thrown back to the login screen. Typing mathematica in the terminal produced the same effect. Typing mathematica -cleanstart or mathematica -mesa did not help. Starting Gnome session with or without effects did not help Launching mathematica under another user account did not help. I still can run text-only version of mathematica by typing math in the terminal. I don't remember making any changes to my configuration except for installing updates. Is there any quick way to fix this behavior? How can I know which component exactly crashed? Where should I look for crash logs?

• UEFI/GPT Win 7 Load Failure in Dual Boot and no GRUB2 [Ubuntu 12.04]

  - by cristian_jordache

  Configuration: MBB: ASRock X79 Extreme6 Win 7 installed on a INTEL 40GB SSD (GPT partitioned) Ubuntu 14.04 on a CORSAIR 30GB SSD (Ext4 and SWAP) I had Windows 7 installed previously in UEFI mode, using 3 partitions (GPT) and works fine if left alone. In UEFI BIOS settings I can see sometimes a "Windows Boot Manager" and other times (?) a "UEFI Intel" entry for INTEL HDD and Windows will boot properly selecting the one available at that time. I installed Ubuntu 14.04 after Win 7 w/o changing any UEFI BIOS settings and it works fine only if the BIOS is set w/ the Ubuntu partition as the first drive to boot, in AHCI mode. If both SSD drives are connected, the Win7 Intel boot drive can be chosen as first boot device but only as an "AHCI Intel drive" (No "Windows Boot Manager" nor "UEFI Intel device" options available in BIOS Boot menu) and Win7 will not load properly as long as the Ubuntu Crucial SSD is NOT PHYSICALLY DISCONNECTED. Windows will try, start booting for few seconds but will fail replacing Win7 logo and that startup animation with w/ the "old" white progress bar and then and will notify that there is a issue and prompt the user to try to Load Win 7 in Normal Mode again or try a Recovery Mode to fix it. If I let Windows INTEL HDD boot via BIOS/UEFI - Windows Boot manager selection, I may see the purple screen of Grub2 loaded for a while, but there's no selection for Ubuntu or Windows and/or then machine is not booting, showing a black screen and a small command prompt cursor blinking on top. So far the only option I see to have Ubuntu boot side by side w/ Win 7 is to reformat the Win7 SDD and set it boot in legacy BIOS mode with a MBR instead of GPT. Per my understanding this is a quite complex issue to fix (Rod Smith's answer was pretty helpful: UEFI boot on my Asus k52f) but any other suggestions are welcome. I find a bit odd that I can boot properly Windows7 SSD or an Ubuntu DVD using a DVD drive set in UEFI-BIOS in "AHCI mode" and w/ using "UEFI/Windows Boot Manager" booting option but I cannot boot a secondary SSD-HDD w/ Ubuntu having the same BIOS/UEFI Boot configuration. Looks like plugging the second SSD [the Ubuntu partition] is interfering with boot options in UEFI-BIOS.

• A dacpac limitation – Deploy dacpac wizard does not understand SqlCmd variables

  - by jamiet

  Since the release of SQL Server 2012 I have become a big fan of using dacpacs for deploying SQL Server databases (for reasons that I will explain some other day) and I chose to use a dacpac to distribute my recently announced utility sp_ssiscatalog (read: Introducing sp_ssiscatalog (v1.0.0.0)). Unfortunately if you read that blog post you may have taken note of the following: Ordinarily a dacpac can be deployed to a SQL Server from SSMS using the Deploy Dacpac wizard however in this case there is a limitation. Due to sp_ssiscatalog referring to objects in the SSIS Catalog (which it has to do of course) the dacpac contains a SqlCmd variable to store the name of the database that underpins the SSIS Catalog; unfortunately the Deploy Dacpac wizard in SSMS has a rather gaping limitation in that it cannot deploy dacpacs containing SqlCmd variables. I think it is worth calling out this limitation separately in this blog post because its a limitation that all dacpac users need to be aware of. If you try and deploy the dacpac containing sp_ssiscatalog using the wizard in SSMS then this is what you will see: TITLE: Microsoft SQL Server Management Studio ------------------------------ Could not deploy package. (Microsoft.SqlServer.Dac) ------------------------------ ADDITIONAL INFORMATION: Missing values for the following SqlCmd variables:SSISDB. (Microsoft.Data.Tools.Schema.Sql) ------------------------------ BUTTONS: OK ------------------------------ The message is quite correct. The SSDT DB project that I used to build this dacpac *does* have a SqlCmd variable in it called SSISDB: Quite simply, the Dac Deployment wizard in SSMS is not capable of deploying such dacpacs. Your only option for deploying such dacpacs is to use the command-line tool sqlpackage.exe. Generally I use sqlpackage.exe anyway (which is why it has taken me months to encounter the aforementioned problem) and have found it preferable to using a GUI-based wizard.

• Visual Studio 2008 “Format Document/Selection” command and a function named “assert” in JavaScript c

  - by AGS777

  Just have found some funny behavior of the Visual Studio 2008 editor.  Sorry if it is already well known bug. If you happened to have a JavaScript function named “assert” in your code (and there is pretty high likelihood in my opinion), for example something like: function assert(x, message) { if (x) console.log(message); } then when either Format Document (Ctrl + K, Ctrl + D) or Format Selection (Ctrl + K, Ctrl + F) command is applied to the document/block containing the function, the result of the formatting will be: functionassert(x, message) { if (x) console.log(message); } That’s it. function and assert are now joined into one solid word. So be aware of the fact in case you suddenly start receiving  strange exception in your JavaScript code: missing ; before statement functionassert(x, message) And no, it is not an April Fool's joke. Just try for yourself.

• Port forwarding (portmap) works only locally

  - by Tag Wint

  There are four hosts hostA winXP hostB Win2003 hostC Linux RHEL hostD Linux RHEL hostA cannot connect to C and D directly, but B can hostA connects to hostB using VPN hostB and hostC belong to the same subnet1 hostD is in subnet2 From hostA I need to connect to hostC and hostD by SSH. Now I can do it as follows: 1.connecting from hostA to hostB by RDP logon and there: 2.start putty client. I'd like to omit step 1 and connect from A to C and D directly On hostB I have admin acoount and configure port forwarding as follows: netsh interface portproxy add v4tov4 listenport=N1 connectaddress=hostC_IP connectport=N2 netsh interface portproxy add v4tov4 listenport=N3 connectaddress=hostD_IP connectport=N2 netsh interface portproxy show all: Listen on IPv4: Connect to IPv4: Address Port Address Port --------------- ---------- --------------- ---------- * N1 hostC_IP N2 * N3 hostD_IP N2 Now from hostB I can connect to either C and D: ssh localhost:N1 ssh localhost:N3 from hostA ssh hostB:N1 works too, but ssh hostB:N3 DON'T I guess the reason might be different subnets, still have no idea how to fix it. What should I do?

• Windows 7 Boot Screen Resolution/Aspect Ratio

  - by Joe

  I have been using my Windows 7 PC with my 46" Samsung HDTV with 1920x1080 resolution. The boot screen seems to always be at 1024x768 resolution and the aspect ratio doesn't match the 1080p ratio. I read on a msdn blog that microsoft only made the boot screen in one type of resolution so that cannot be changed. The result is that on my TV the boot screen seems to look stretched out. Is there a way to make change the aspect ratio or crop it in someway? Is there any method at all to make it look normal or just better without being stretchy looking?
