  • Integration features enabled but drives not available

    - by dsjbirch
    Frustratingly, after a recent update to Windows XP mode integration features, the availability of shared disks from the hosts has been impaired. Does anyone know any kind of workaround or fix (excluding dropbox et al)? I have tried completely uninstalling and reinstalling as per http://www.sevenforums.com/virtualization/63710-refreshing-xp-mode.html#post568715 At one point restarting the machine appeared to have worked, but today again I am without access to my host. Interestingly audio and copy and paste to and from the machine are working.

  • Local dns for testing websites using mobile devices

    - by Morpheu5
    Hi. I have no idea where to start from so sorry in advance if this topic has already been discussed. I usually develop web sites using my laptop as a development server, and recently I needed to test a web site using various mobile devices that can connect via wifi. Having no real AP, I set up a ad-hoc network using my laptop's wireless card and the devices can correctly browse the Internet and access the laptop's web server. The setup is as follows: subnet: 192.168.1.0/24 gateway to the Internet (wired adsl router/modem): 192.168.1.1 laptop: 192.168.1.64 (eth0, wired if connected to the gateway) and 192.168.1.32 (eth1, wifi if somewhat bridged to eth0) mobile devices (same for all, I only use one of them at any time for simplicity): 192.168.1.11 with default gw 192.168.1.1 Now, if I open either 192.168.1.32 or 192.168.1.64 from the mobile devices, I correctly get the default host of my Apache configuration. However I usually work with virtual hosts for many practical reasons, one of which being Drupal's peculiar implementation of multi-sites. For those who don't know how this works, Drupal takes the request's hostname and searches into its sites/ subdirectories for an appropriate configuration file. So, for example, suppose I request www.example.com, then Drupal would search for a config file in the following directories: sites/www.example.com/ sites/example.com/ sites/com/ sites/default/ So I decided to adopt the following style of virtual hosts: if the website I'm working on will be accessible using www.example.com I set up a sites/www.example.com/ directory and create a virtual host for local.www.example.com so Drupal have no trouble finding it. I've been told this is suboptimal from a dns point of view since I'd have to create an authoritative entry for example.com and turn Bind on only when I'm supposed to access the local copy, which is weird. However, if this is the only path I can follow, I still have some problems with Bind's configuration, as I couldn't find any guide that tells me in a clear, noob-friendly way, how to set up such an entry. On the other hand, I was wondering if I could set up an authoritative entry for local, so I could access www.example.com.local and tell in some way (which I don't even know if this is possible) Apache to put www.example.com instead of www.example.com.local in the relevant environment variable. Anyway, I have a last problem, sort of: when I launch Bind in debug mode with high verbosity, and make 192.168.1.32 as the primary dns for the devices, the output doesn't say anything about requests being made from the devices to Bind, so I'm not even sure it comes into play. As you can see, I'm a complete noob at these matters, but I'm eager to learn, so any help/pointer will be appreciated.

  • sudo with -u via ssh -t in a crontab

    - by DJK_devel
    I'm trying to create a cron job that uses ssh to login to a remote server and run a script as a different user. I try: * * * * * source $HOME/.keychain/$HOST-sh && sudo -u $USER $PATH/$SCRIPT but this doesn't work because there is no -t option specified for ssh. The cron job needs to source the keychain file in order to work without a password, but I'm not sure where to include the -t option for ssh in this instance.

  • debugging JBoss 100% CPU usage

    - by Nate
    We are using JBoss to run two of our WARs. One is our web app, the other is our web service. The web app accesses a database on another machine and makes requests to the web service. The web service makes JMS requests to other machines, aggregates the data, and returns it. At our biggest client, about once a month the JBoss Java process takes 100% of all CPUs. The machine running JBoss has 8 CPUs. Our web app is still accessible during this time, however pages take about 3 minutes to load. Restarting JBoss restores everything to normal. The database machine and all the other machines are fine, only the machine running JBoss is affected. Memory usage is normal. Network utilization is normal. There are no suspect error messages in the JBoss logs. I have set up a test environment as close as possible to the client's production environment and I've done load testing with as much as 2x the number of concurrent users. I have not gotten my test environment to replicate the problem. Where do we go from here? How can we narrow down the problem? Currently the only plan we have is to wait until the problem occurs in production on its own, then do some debugging to determine the cause. So far people have just restarted JBoss when the problem occurred to minimize down time. Next time it happens they will get a developer to take a look. The question is, next time it happens, what can be done to determine the cause? We could setup a separate JBoss instance on the same box and install the web app separately from the web service. This way when the problem next occurs we will know which WAR has the problem (assuming it is our code). This doesn't narrow it down much though. Should I enable JMX remote? This way the next time the problem occurs I can connect with VisualVM and see which threads are taking the CPU and what the hell they are doing. However, is there a significant down side to enabling JMX remote in a production environment? Is there another way to see what threads are eating the CPU and to get a stacktrace to see what they are doing? Any other ideas? Thanks!

  • Will terminal keep executing a command after i disconnect my VNC session?

    - by Fer
    I established a remote session in a MacOSX (10.6.8) from my PC (Windows7) using VNC. I initiated terminal and it is currently executing a task that will take probably 1 day before completing. Should I expect that even if I disconnect the VNC session, Terminal will keep running after I disconnect? I assume so since I used VNC just to remotely start the process but want to double check. Can anybody tell me if I am wrong?

  • Apache shuts down from time to time

    - by Dugi
    I'm having trouble with my VPS as it keeps shutting apache down at least twice a day. The server is running on CentOS 6 with the latest apache. By shutting down I mean I have to go into SSH and type in this command in order to bring it up again: /sbin/service httpd start I'm not very good with servers and my host doesn't seem to have a nice customer service. Any help would be appreciated as these unexpected downtimes really know to kill one's mood.

  • Profile pictures are neither displayed or stored in my Status.Net installation

    - by Ced
    I am running Status.Net 1.0.1 on my webhosting service. When I subscribe to a remote OStatus account, the avatar is neither displayed nor stored in my avatar/ directory. The INSTALLATION file suggests setting the avatar/, background/ and files/ directories to webserver writeable, but this does not help. Has anybody gotten this to work or could anyone point me in the right direction for a solution?

  • How to change user for more rights on a SFTP client?

    - by Zenklys
    It is always suggested on first step to disable the remote root login for the SSH protocol. I have a low-right user able to connect via SSH and once connected, I simply su in order to gain more rights. Now when using a sFTP client, I use my low-right user and am thus able to do next to nothing. My question is : Is it possible to change user after login using 3rd party client, such as Transmit, Cyberduck, Filezilla ? PS : Mac clients would be great ;)

  • Does QEMU's performance (still) lag VirtualBox's and is there a way to improve it without kvm?

    - by Catskul
    I've noticed several articles that have claimed that QEMU is slower than VirtualBox (without hardware assistance) but several are years old, and the newest seemed to be from last year. Is it true that QEMU is slower than VirtualBox? If so why? Are there any tricks to close the performance gap? Some of my host systems do not have virtualization support so I'm especially interested in performance tips that work without the kernel module.

  • Using Dropbox as a cloud based file share - does everyone need an upgraded account?

    - by aSkywalker
    We have a file share in our small office (3-5 users). We now have the need for the files to be accessible outside of the office. I like the idea of dropbox - we have been using it for small remote sharing. If we buy the upgrade account, and move 30 to 70 gigs of files to it, will every user have to have the pro account? I have submitted this question to dropbox - but thought that the advice of users here would also be valuable

  • WLAN adapter on Ubuntu Server inside Hyper-V

    - by Firefox333
    I need to set up an Ubuntu server as a router. However we need to make it wireless and wired. I need a WLAN adapter for the wireless part of the router. I get my Internet connection on my server through my wireless adapter from my host but it automatically sees it as an Ethernet adapter instead of as a wireless adapter. Is there any way of making a (virtual) wireless adapter on Ubuntu server 12.04 inside a hyper-v machine?

  • Can't install .NET 4.0 on Windows XP virtual machine! (VMWare Player)

    - by Vercas
    So, every time I try to install .NET Framework 4.0 on my Windows XP Professional SP3 VMWare Player virtual machine, I get a fatal error. It doesn't work with either Windows Update, the Web Installer or the normal installer! I don't know if it matters (AND I HOPE IT DOES NOT), but the host OS's Operating System drive is encrypted, and the VM HDD file resides on that partition. I don't think it matters because other programs can be installed! And downloaded!
