  • Glassfish and SSL [closed]

    - by Richard
    I'm struggling to get SSL working on Glassfish 3.1.1. I've been following tutorials like http://javadude.wordpress.com/2010/04/06/getting-started-with-glassfish-v3-and-ssl/ and SO posts like this Issues with setting up SSL on Glassfish v3 The above links are for information only. I've summarised what I've done below. As far as I can tell I'm doing everything correctly but I'm getting this error: SSL configuration is invalid due to No available certificate or key corresponds to the SSL cipher suites which are enabled Some background of what I have done: My cert is from GoDaddy. I generated the CSR from a new keystore (keystore.jks), then imported the resulting certs back into the same keystore and set the keystore password to the same pwd as the GF master password. Then created a new SSL listener in GF and pointed it at my keystore file (which I copied into domains/domain1/config). Set the Nickname to the alias of my cert (which is something liem 'mydomain.org' i.e. the name that I get when I run keytool -list. In my ciphers section in the network listeners page, I leave the defaults in place (empty, which means all ciphers are available I think). In domain.xml I've replaced all instances of s1as to 'mydomain.org'. This is the question: What exactly is causing the error highlighted? I'm guessing it's a mismatch between my listener config and aliases in my keystore, or something similar, but I'm not really sure what. Thanks

  • Looking for a free SMTP server program

    - by Richard
    Hello all, I am looking for a free SMTP server. I am currently using Free SMTP Server http://www.softstack.com/freesmtp.html This software works great other than the fact that it can only send 10 messages a day. This is a bit of a problem seeing that the software I am writing needs to send a message every half hour. Anyone knows of a good piece of software that does the same thing, but does not limit the amount of messages that can be sent in a day? I am using Windows XP, so software must be Windows friendly

  • 64-bit Windows 7 gets stuck on logo screen on bootup

    - by Richard B
    I've had a PC running Windows 7 in my office which I'm not using at the moment (cause I'm working elsewhere as a consultant atm), I'm only accessing the PC using Team Viewer (http://www.teamviewer.com/) which means the PC has been running for quite some time now. I've restarted it maybe twice a week though. A few days ago I couldn't access it using Team Viewer and when I got to the office the screen was black with only the mouse pointer showing. The PC has four hard disks, three of them (all 1Tb) is using RAID 5. This is what I've done so far: I reboot and everything seems to load correctly. I get to a screen that gives me two choices - boot Windows normally or perform a startup repair. Choosing to boot Windows only gets me to the Windows 7 logo screen which only animates over and over again. Choosing to repair gets me to the repair screen that "checks for problems" and then it gets stuck on the "Attempting repairs..."-screen (I let it run for about 24 hours before giving up). What is the next step to take? I don't have any backups and no system restore points saved. I can access files and folders through a terminal window using a Windows 7 DVD so I guess nothing is lost yet... Please help me, thanks!

  • ruby on rails server is intermittently slow

    - by Richard
    My rails installation was chugging along nicely. Last night we had to perform a hot-patch with was really a standard deploy of some exception code. Once capistrano finished the operation one of our admins discovered that there were two long running passenger processes. While we have deployed release over the past two weeks it would appear that these processes have been here and alive the whole time. Granted they could have been zombies or any other artifact and at this point we do not know what state they were in. Which leads me to the question: There are so many moving parts between the rails application and the OS/hardware that being a SME is probably no longer possible. So; how does a sysadmin perform root-cause analysis with any certainty? And: When do I just start rebooting servers?

  • RAID10 Without BBU, With UPS

    - by Richard
    My datacenter says that each rack has primary and backup power on each rack. I assume this means there is a UPS for each server. Therefore, do I have any need of getting a BBU for the following setup? Intel Cherry 520 SSD x 4 RAID 10 LSI-9260 with WRITEBACK CACHE ENABLED I have heard that without a BBU the data in the cache could be lost. Since my needs aren't mission-critical, I can afford to lose some data. But would the rest of the data on the HD be corrupted?

  • How is a nameserver chosen when DNS resolution occurs?

    - by Richard
    I have a few domains hosted on nameservers at Zerigo. Zerigo have 5 nameservers and I have all 5 in the nameserver records for my domains. The nameservers are in different geographical locations (3 in the US, one in London, and one in Amsterdam). When someone goes to a domain of mine and the DNS resolution occurs, how will it choose a nameserver? Will it always go to the nearest geographical one? Will it go to the one with fewest hops? Will it just choose one at random? (This is assuming all 5 are functioning perfectly). Thanks EDIT: And does it make any difference which order I list the nameservers in on the domain name records?

  • Ping results "echo'd" out to a text file on Windows XP machine has unusual character rather than the outcome

    - by Richard Rice
    Here is the situation. I have a Windows XP machine that I would like to ping another machine and send the output to a text file for review at a later date. This is quite a standard question with several answers on this website and others. The issue I have is that when reviewing the txt file afterwards, the outcome of the ping appears as a strange character. A screenshot of the text file output can be found at the following link. Please note its the first 8 ping outputs that have a strange character. The %%B was me hoping that would output what I wanted! (Cannot upload image to any hosting websites because the company I work for seems to be afraid of them ....) Here is the code I'm using: @echo off For /f "tokens=1-2 delims=/:" %%b in ("%TIME%") do (set mytime=%%a%%b) PING 1.1.1.1 -n 1 -w 1000 >NUL for /f "tokens=*" %%A in ('ping 192.168.5.2 -w 10 -n 1') do (echo %date% %time% %%A >> C:\Temp\Ping_Checks\GarrickSide.txt && GOTO Ping ) :Ping PING 1.1.1.1 -n 1 -w 1000 >NUL for /f "tokens=* skip=2" %%A in ('ping 192.168.5.2 -w 10 -n 1') do (echo %date% %time% %%A >> C:\Temp\Ping_Checks\GarrickSide.txt && GOTO Ping ) This code works fine on a Windows 7 machine, but not on a Windows XP machine. It appears that the echo command isn't outputting the right data, but I don't understand this enough to correct it. Can anyone spot where I'm going wrong?

  • What causes this sonar sound on OS X?

    - by Richard Metzler
    Both of my Macs play this sonar sound that sounds like "ping ping ping ping" with a small amount of delay / echo. It occurs to me that it is played once a day but I'm not sure why. I checked iCal but didn't found anything (I don't use iCal anyways but maybe it's connected to Google calendar or my iPhone). I've heard this sound played by both my MacBook and my iMac but not yet simultaneously. Update This sound is not submarine.aiff. It sounds much more like what skub linked to but there are 4 "pings" instead of 1. It is played at different times (today around 5pm and again at 8.45, but as far as remember not everyday). That's why I'm not sure I could record it, but I could try. The sound might come from my iPhone, though I'm not sure which apps are alowed to play sound when they are not running. Also I don't see any indication in the message center or something similar. I think I have to start taking notes on which apps running.

  • 4GB Memory Upgrade for Acer Aspire 5102WLMi

    - by Richard Slater
    I have bought a 4GB memory upgrade (2x 2GB PC2-5300 SODIMM) for my Acer Aspire 5102WLMi (Aspire 5100 Series) laptop, I installed the two memory modules correctly however with 4GB installed the laptop refuses to POST. I have tried the following: Tried both 2GB SODIMMs without the other (Worked Fine) Tried the original 512MB SODIMMs (Worked Fine) Tried with original 512MB SODIMM and new 2GB SODIMM (Worked Fine) Tried swapping over the 2GB SODIMs (Didn't Boot) Left the computer for 10 minutes with both 2GB SODIMMs installed (Didn't Boot) Checked latest BIOS installed (No Change) The Crucial website said that the laptop supported 4GB of RAM as do several other sites through found through Google, up until now I was fairly confident this would work. Couple of questions that would be good to have answered: Question: Has anyone got an Acer Aspire 5100 Series running with 4GB RAM? Answer: Yes, I have now got one working with 3.75GB Usable, the rest is occupied utilized by the Graphics Card. Question: Any tips on getting this to work; is there a CMOS reset switch? Answer: Yes there is, if both SODIMMs are removed two very small interlocking PCB tracks are revealed. If these are shorted together with a screwdriver the BIOS will be reset. Thanks.

  • pfSense router gives DNS rebinding warning when accessing subdomains

    - by Richard Maddis
    I have just set up a router running pfSense on our network and forwarded the appropriate ports. I have a small web server running in my network, and a domain name pointing to our (WAN) IP. When accessing that domain name, everything works fine. However, when accessing a subdomain of the domain name, pfSense will give a DNS rebinding warning. This did not happen back when I used a DD-WRT router. What is the proper way to fix this? The DNS records for the subdomain also point to the same address (I use a virtual server to differentiate the subdomains.)

  • Galaxy Tab 3 producing continuous LightSensor error in LogCat

    - by Richard Tingle
    I am using a Galaxy Tab 3 as a test device for writing an android app. As such I'm interested in the output of the LogCat which is being filled with these error level messages. The device itself appears to work correctly, apps which rely on the light sensor correctly respond to it and the number in the error itself goes down if the light sensor is obscured. If I wasn't using it to develop apps I wouldn't even be aware of the issue but I believe it is an issue with the device itself not my app: simply plugging the tab 3 into the computer and using Eclipse - ADT to look at the LogCat without any app running leads to these errors being shown. I know I could filter the LogCat to ignore these errors but inconvenience aside; they concern me. A sample of the log cat is below (it generates errors continuously). This is on verbose so it includes some debug level (D/) messages as well as the error level messages (E/). How can I correct the device to no longer generate these errors. 06-11 10:08:45.789: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:45.992: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.195: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.398: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.601: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.804: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.007: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.210: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.414: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.617: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.820: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.023: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.039: D/dalvikvm(15201): GC_CONCURRENT freed 1947K, 17% free 16973K/20359K, paused 13ms+13ms, total 50ms 06-11 10:08:48.226: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.429: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:48.835: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.039: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.242: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.445: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:49.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:49.648: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.851: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13

  • Are there any known issues with Windows-8 installed on a VHD?

    - by Richard
    I installed Windows 8 preview on a VHD image and it seemed to work until I actually started using it. I´m seeing terrible performance. Installing anything makes everything else "stutter" or freeze for up to a couple of seconds at a time. I looked up hard disk performance in the task manager and this is what I found: It doesn't seem right it has 2500ms response time while reading/writing at those speeds. Is this an issue with my drive, installation or VHDs in general?

  • Virtual Box start from dual boot systme

    - by Richard
    So for a long time now, I've been running Linux on a dual boot system with Windows 7. I don't run Windows very often, however it happens enough now that I started looking at alternatives to reboots. A friend showed me Parallels on his Mac, and I fell in love with the concept of Virtual machines. Since Sun has been in the Unix space since the beginning of time, they likely have the best solution for Linux (big assumption I know). Anyway, to avoid re-installing windows, as I have it set up the way I like it now, I was wondering if there was a way to point to the existing install and boot from that point. Linux is installed on /dev/sda Windows is on /dev/sdb Having never done this before a little handholding would be great as to what step I should take. Thanks for any help in advance!

  • Need data on disk drive management by OS: getting base I/O unit size, “sync” option, Direct Memory A

    - by Richard T
    Hello All, I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: the database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it. When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it. I have been looking for information on how to ensure these are so for CENTOS and Ubuntu, but can't seem to find anything at all! I want to be able to check these things and change them if needed. Any and all input appreciated.

  • Oracle (xe) 10 vs 11 . Have I lost the SQL tuning pages ? Am I going out of my mind?

    - by Richard Green
    Ok .. so perhaps the title needs calming down a bit, but basically I am after the xe 11g equivalent of the pages that you can see here : http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/getstart.htm#BABHJAGE whcih you can then navigate to stuff like "top 50 queries" and "longest running queries" etc etc. For the life of me, I can't find that on the most recent xe edition. Please can someone direct me to where I might find these very useful admin pages ! Or was I imagining it all along :-/ Edit: These are the pages I am after: http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/monitoring.htm

  • Is there any way to change the VirtualBox "snapshot" folder for an existing virtual machine?

    - by Richard J Foster
    I have a virtual machine which is currently using a folder on the C: drive to store its snapshots. I have copied the contents of the "Snapshots" folder to an alternate drive, but whenever I go into the General / Advanced settings section for that virtual machine and change the snapshot folder to the new location it resets back to the original location. What do I need to do to get VirtualBox to recognize the new location for the snapshot files?

  • Is there a keyboard shortcut to close windows from the Windows 7 taskbar window selector?

    - by Richard Szalay
    If, for example, Windows Explorer is in the first position of the taskbar and there are multiple explorer windows open, holding START and pressing 1 will cycle through the available windows and display an x on the top-right of the selected item that can be clicked to close the window. Is there a keyboard shortcut to close the selected window while still keeping the window list around (moving to the next item)?

  • How to setup KVM partitioning?

    - by Richard
    I'm trying to install SolusVM/KVM on a server with one 500 GB HD and one 256 SSD. I am a complete beginner at Linux. SolusVM has a script on the site to download and install automatically, but how do I specify to install the script on the 500 GB HD and put the virtual machines on the SSD? And how should my partitioning look like? I want KVM isos and stuff on HD and virtual machines on SSD. Thanks a lot.

  • Top 5 reasons for using ASP.NET MVC 2 rather than ASP.NET MVC 1

    - by Richard Ev
    I've been using ASP.NET MVC 1 for a while now, and am keen to take advantage of the improvements in MVC 2. Things like validation seem greatly improved, and strongly-typed HTML helper methods look great. So, for those of you who have real-world practical experience of using ASP.NET MVC 1 and are now using MVC 2, what are your top 5 reasons for using MVC 2?

  • Mocking HttpContext in .NET MVC2 using Moq

    - by Richard
    Hi, This was working in MVC 1, but has broken in MVC 2. I'm mocking the HttpContext so I can test routes. The code was originally taken from Steven Sanderson's book. I've tried mocking some extra properties as suggested in this comment but it hasn't fixed it. What am I missing? This is the start of my test code. routeData is null when this code completes. // Arange RouteCollection routeConfig = new RouteCollection(); MvcApplication.RegisterRoutes(routeConfig); var mockHttpContext = makeMockHttpContext(url); // Act RouteData routeData = routeConfig.GetRouteData(mockHttpContext.Object); This method creates my mock HttpContext: private static Mock<HttpContextBase> makeMockHttpContext(String url) { var mockHttpContext = new Mock<System.Web.HttpContextBase>(); // Mock the request var mockRequest = new Mock<HttpRequestBase>(); mockHttpContext.Setup(t => t.Request).Returns(mockRequest.Object); mockRequest.Setup(t => t.AppRelativeCurrentExecutionFilePath).Returns(url); // Tried adding these to fix in MVC2 (didn't work) mockRequest.Setup(r => r.HttpMethod).Returns("GET"); mockRequest.Setup(r => r.Headers).Returns(new NameValueCollection()); mockRequest.Setup(r => r.Form).Returns(new NameValueCollection()); mockRequest.Setup(r => r.QueryString).Returns(new NameValueCollection()); mockRequest.Setup(r => r.Files).Returns(new Mock<HttpFileCollectionBase>().Object); // Mock the response var mockResponse = new Mock<HttpResponseBase>(); mockHttpContext.Setup(t => t.Response).Returns(mockResponse.Object); mockResponse.Setup(t => t.ApplyAppPathModifier(It.IsAny<String>())).Returns<String>(t => t); return mockHttpContext; }

  • WPF: Hide grid row

    - by Richard
    Hi All, I have a simple WPF form with a <Grid> declared on the Form. In this Grid I then have a bunch of Rows: <Grid.RowDefinitions> <RowDefinition Height="Auto" MinHeight="30" /> <RowDefinition Height="Auto" Name="rowToHide"/> <RowDefinition Height="Auto" MinHeight="30" /> </Grid.RowDefinitions> So basically the row with the name "rowToHide" has a few input fields in it, and now I want to hide this row as I don't need these fields. Its simple enough to just set all items in the Row to Visibility = Hidden, but the Row still takes up space in the Grid. So need to do something like setting Height = 0 or something. But that didn't seem to work. You can think of it like this: You have a form, in there we have a drop down saying "Payment Type", and if the person selects "Cash", then hide the row containing the Card details. And it isn't an option to start the form with this hidden already. Thanks everyone!
