  • Need help configurating my Tomcat server without any WAR files

    - by gablin
    I just reinstalled my entire server, and now I can't seem to get my JSP-based website to work on Tomcat anymore.

  • HD movies stutter.

    - by Absolute0
    I just put together a new system build in the hopes that all of my daily tasks would run smoothly and without any hiccups. Unfortunately I am still seeing some sound and sometimes video stuttering when playing HD movies in VLC (no problems with xvid/divx files). My setup is as follows: Intel core i5 750 quad core 2.66mhz 4GB ram asus p55 motherboard radeon hd 5570 video card 650gb 7200rpm western digital sata HDD 23" Nec ea23wmi monitor Operating System: Windows 7 What might be the main bottleneck that needs upgrading to fix my delays? Seems like the hard drive might be the problem but anything faster than 7200rpm is beyond my budget for a decent hard drive. Could it be anything else?

  • Migrating XenServer VMs from Intel to AMD servers

    - by John Smith
    I need to replace my XenServer 6.1 resource pool hardware. I currently run Intel hardware and I have to move to AMD hardware (corporate politics and budget stuff, blah blah blah). I have downtime available so I can use cold migration - live migration is not required. I will also have the new hardware (AMD) alongside the old hardware (Intel). The XenServer docs say there may be problems exporting from one arch and importing to another "may not work" - http://docs.vmd.citrix.com/XenServer/6.1.0/1.0/en_gb/guest.html#importing_vms - but mentions nothing about simply turning off the VM on one arch and then powering it back on new arch. VMs are a mix of OS - some Windows, some Linux, multiple versions. Is this something that can be done with no problems, or are there problems I need to be aware of?

  • Old PCI Video Card and PCI-Express ATI Radeon HD 4200 Pro Living Together

    - by Adam Driscoll
    I have two video cards installed in a Dell Optiplex 745. The PCI card is from 2001 and I was hoping to be able to install it, allowing me to have 3 monitors. The Radeon is already running two itself. The problem is that when I boot the box with default BIOS settings the PCI card displays video to the single display but not the other two. In device manager I can see that both video cards are visible with drivers loaded correctly but underneath monitors I only have a single Generic PnP monitor from the VGA connection to the PCI card. If I switch the BIOS setting to force PCI-E I get the Radeon to display to the two other monitors. When I check device manager with this configuration I see that the PCI card displays an error saying the driver could not be started. Any ideas?

  • Windows screen shots via command-line SSH session

    - by Geoff Fritz
    I've browsed the handful of "screen capture" queries here, but I was unable to find anything which addressed my specific need. I'm looking for a command-line tool that I can run via remote SSH connection (by way of the cygwin sshd daemon). There are several to choose from, but the few I've tried (ImageMagick, nircmd, and MiniCap) all result in a blank screen. I assume that this is due to the remotely logged in user not having a proper graphical console session running. The goal here is automate screen capture and retrieval of the main system console (what one would see if they were looking at the physical monitor) through the use of ssh script from a Unix host: ssh user@windowshost "screencap --output /tmp/console.jpg" scp user@windowshost:/tmp/console.jpg /some/destdir Note that these must be done on demand, so polling a remote directory that has snapshots dumped periodically will not work. Bonus points for programs that are open source and have a portable install (so I don't need to RDP/VNC into the machine to run a graphical installer).

  • Disable laptop's display on boot when used with external display

    - by Ryan
    I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.) The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising. Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?

  • interesting uses for a headless host running Ubuntu.

    - by Manuel
    Hey! So, I have configured a pc with no monitor, keyboard or mouse running Ubuntu. I use it as a ssh server, file backup, web server, etc. Though, it seems as if I could use it for sooo much more. The problem is I can't think of many more uses. What interesting uses of a headless host have you heard of? Is there a cool trick you want to share? Thanks! Manuel

  • application monitoring tools

    - by Shachar
    we're an ISV about to deploy our SaaS application over the internet to our end users, and are currently looking for an application monitoring solution. In addition to monitoring the usual OS-level suspects (I/O, disk space, logs, CPU, RAM, swapping, etc.), we're also looking to monitor, alert and report on internal application events, conditions, and counters (think queue size for internal service, or latency of a service we're getting from a third party via custom APIs). We're started looking at Nagios, Zenoss, etc., but found out those do only low-level stuff, and are currently looking at MOM and ManageEngine. Still, they are far from being an custom app monitoring tool. So - do you have anything to suggest?

  • How can I stop my laptop display from flickering when I connect my TV?

    - by Lord Torgamus
    I have a laptop with an HDMI output port running Vista, and an HDTV with HDMI input ports. The laptop is set to extend its desktop onto a second monitor. When I connect the computer to the TV with an HDMI cable, my laptop screen usually flickers rapidly. Most of the time it lasts for about 30 seconds, but sometimes it lasts for several minutes and once in a while it doesn't happen at all. It wouldn't be so bad except that the cursor moves back to the center of the laptop screen with each flicker, so I can't really do anything until the machine decides it's ready to calm down. I haven't been able to find any pattern at all for the causes or duration of the flickering. It doesn't seem to matter what programs the laptop is running when I connect it to the TV, whether I enable the extended display before or after I connect the TV or which HDMI port/cable I use. What could be causing this, and how can I make it go away?

  • What was your most expensive computer rig?

    - by AlbertoPL
    I'm curious as to how much people are willing to spend on a typical computer. My most expensive machine is a gaming rig complete with an ATI Radeon HD4850, Wolfdale 3.0 GHZ Intel Core 2 Duo, 500 Gb hard drive, Antec 900 computer case, the works. I also have a 2-monitor set up. I'd have to say this thing has cost me a little more than a grand at this point, and I'd put the total value of the components at roughly $1300. So, how far have you gone with your computer rigs and has it been worth it?

  • Thomson TG585v7 router - promiscuous mode

    - by Nikita
    I have a TG585v7 as a router with several machines plugged into it. In the default setup, the packets are only delivered to the specific machine but I want to be able to setup to monitor all network traffic on one of the machines, i.e. I need those packets to be picked up when my ethernet card is in promiscuous mode. Is this possible? Guide here has this "mcastpromisc Make the IP interface multicast promiscuous. OPTIONAL", is this what I am looking for? Does it mean I need to manually add all my machines by their MAC addresses to be able to receive packets destined for them? Or am I out of luck and I need to get a better router?

  • Not able to access other machines on network

    - by TheVillageIdiot
    Hi I'm running Windows 7 Enterprise (32bit) on my laptop. For some time I'm not able to access other machines using \\192.168.xxx.xxx. I've installed VM Ware player on my machine few days back but I don't remember if it happened just after that or there is some other reason behind it. EDIT:- I've disabled VMWare Bridge Protocol but still no effect. Please help me. PS:- I've used both wireless and wired networks. Network sharing is enabled and I can ping other machines but cannot access network shares. I get following message: \\xxx.xxx.xxx.xxx You might not have permission to use this network resource. Contact the administrator of this server to find out if you have acess permissions. The request is not supported. EDIT (2):- Network Discovery, File and Printer Sharing, Folder sharing are all on.

  • Two different sites, same IP, same top-level domain, on IIS 7.5 -- one works and the other displays HTTP 404 error

    - by user717236
    I'm running a Windows 2008 R2 box with IIS 7.5 as the web server. On IIS, I have two websites: mysubsite1.mysite.com and mysubsite2.mysite.com. There is only one IP on the server and both sites share this IP. Here is how I have the bindings configured: mysubsite1.mysite.com works fine. However, mysubsite2.mysite.com gives me the following error: Not Found HTTP Error 404. The requested resource is not found. Now, if I change the Host name field for mysubsite1.mysite.com to blank and restart the web server, both sites work! The question is why is the host name field for the first site causing an HTTP 404 error for the second site when both sites' Host name fields are filled? I would appreciate any insight. Thank you.

  • Asp.net mvc application deployment / security issues

    - by WestDiscGolf
    I'll start with appologies; I wasn't sure if this was best posted here of Server Fault so if its in the wrong place then please move :-) Basic information I have written the first module of a new application at work. This is written using Visual Studio 2010, targetting .net 3.5 (at the moment) and asp.net mvc 2. This has been working fine during development running on the built in Development server from VS but however does not work once deployed to IIS 7/7.5. To deploy the application, I have built it in release mode and created a deployment package by right clicking on the project in the solution explorer (this will be done with an automated build in tfs once upgrade from the beta). This has then been imported into IIS on the server. The application is using windows/domain authentication. Issue #1 I can fire up internet explorer and browse to the application from a client computer as well as on a remote desktop connection. I can execute the code which reads/stores data in Session fine from the IE instance on the remote desktop but if I browse to it from the client pc it seems to lose the session state. I click on the form submit and the page refreshes and doesn't execute the required code. I've tried setting with; InProc, SQLServer and StateServer. but with no luck :-( Issue #2 As part of the application it views PDF and Tiff documents on the fly which are on a network share on the office network and creates thumbnails if the document hasn't been viewed before. This works if running on the machine the application is deployed to; however when browsing from a client pc I get an error saying: Access to the path '\\fileserver\folder\file.tif' is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path '\\fileserver\folder\file.TIF' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. As this is on a different server the user is not accessible. To get round this I have tried: 1 - setting the application pool to run as domain administrator (I know this is a security risk, but I'm just trying to get it to work at the moment!) 2 - to set the log on account for World Wide Web Publishing service to be the domain admin . When trying to restart the service I get ... Windows could not start the World Wide Web Publishing Service service on the Local Computer. Error 1079: The account specified for this service is different from the account specified fro the other services running in the same process. Any pointers/help would be much appriciated as I'm pulling my hair out (of what little I have left). Update I've been using this funky little tool I found - DelegConfig v2 beta (Delegation / Kerberos Configuration Tool). This has been really usefull. So I've got the accessing of the file share working (there is a test page which will read the files) so now I've just got the issue of passing through the users credentials through to the SQL Server (wans't my choice to do it this way!!) to execute the queries etc. but I can't get it to log on as the user. It tries to access it as "NT Authority\Network Service" which doesn't have a sql login (as should be the logged on user). My connection string is: <add name="User" connectionString="Data Source=.;Integrated Security=True" providerName="System.Data.SqlClient" /> No initial catalog is specified as the system is over multiple dbs (also wasn't my choice!!). I really appriciate all the help so far! :-) Any further hints?!

  • Can a Mini DisplayPort to HDMI cable support resolutions above 1920x1200?

    - by cnst
    Is it theoretically possible for a cheapo Mini DisplayPort to HDMI cable or adapter to support resolutions above 1920 × 1200, e.g. 2560 × 1440 (QHD)? Or is it always electrically-equivalent to a single-link DVI, and such resolutions above 1920×1200 are out of the question? From empirical evidence, I've tried out some rather expensive brand-name adapter from a local Apple dealer that was marked as HDMI 1.3 compliant with my mid-2013 MacBook Air (5000) and also with X230 (4000), and a QHD monitor, but was only getting a maximum of FHD resulution through such an arrangement.

  • monitoring nfs with monit

    - by Josh Nankin
    I'd like to monitor NFS mounts and the NFS server process using Monit. On the server, I'd need a PID file, but I can't seem to find a way of getting that created with existing configuration files. Is there a way to do this, or has anyone monitored the server in a different way (checking if port 53 is active, etc). On clients, I was thinking of making Monit simply look for a specific file in an NFS mount, and if it's accessible, all is well. Problem is, if the NFS server does go down, file requests usually hang (perhaps even indefinitely, not sure). How would one get around this issue with monit? Any configuration examples would be greatly appreciated!

  • SNMPD - passing values in a trap

    - by ethrbunny
    Im trying to create an SNMP setup to monitor 500-1K machines. Each will be joined to the SNMPTRAPD server via a VPN. When the client system sends its messages, it's sending its internal address instead of the VPN address even though the 'trapsync' command is using the VPN. This will be a problem as many of these system will have DHCP addresses based on location so there will be overlap. What I'd like to figure out is how to pass extra values with the trap so I can identify which system a given trap comes from.

  • Getting out of the Helpdesk. Getting into the system administration.

    - by eric.s
    Today I found out that the job which would have been a promotion for me went to an outside candidate. The position is for a systems admin on our LAN team. I have been working on the helpdesk here for almost two years with another two years experience working it prior. While we are the first tier support we also work in AD, monitor and update certain servers and set up and deploy Windows/Mac images for those we support. What I am looking for here is what can I do to better myself to inside/outside places to move up this ladder? I take what I can from my job - working on projects that I can learn from - but what projects should I be volunteering for? What can I do for myself outside to make me a more viable candidate for a systems admin?

  • How do you prevent the dock from switching monitors in OSX Mavericks?

    - by Brad Dwyer
    In Mavericks, Apple introduced a "feature" where if you hover at the bottom of any screen the dock pops up on that screen. This is disrupting my workflow as I am constantly having the dock pop up when I don't want it to and then I have to go to another window and hover at the bottom for several seconds to get it to go away so I can click on what I was trying to in the first place. I don't want the dock to move; I want it to stay on the bottom of my right-most monitor like it always has. How can I adjust this in OSX Mavericks?

  • How to open embedded Visio files with only Visio Viewer?

    - by Christopher Galpin
    For some bizarre reason Visio Viewer seems incapable of opening vsd files when they're embedded within a (2010) Excel document: However if I open the Excel document with 7-zip, browse to xl\embeddings, extract oleObject1.bin and rename it to a .vsd file extension it opens perfectly fine with Visio Viewer in Internet Explorer. Since this opens fine on a computer with the full Visio installed, my guess is it's trying to launch Visio rather than IE. Is there something I can do to fix this? I've been scanning with Process Monitor and searching with RegScanner comparing a Visio-installed system to a VisioViewer-installed system and there doesn't actually seem to be any sort of registry value giving direction here... maybe it's just the nature of OLE. (If it can't be fixed I'm okay with converting the extracted one to a .png or so to replace the embedded object, but the "solutions" I've found for vsd to image conversion are very poor or non-working, i.e. buggy code, code with Visio dependencies, or online services.)

  • How many cron jobs are too many?

    - by guitar-
    I have a couple of cron jobs for basic maintenance which aren't very resource-intensive. I also have custom task scheduling (which is just calling a .php file and passing information via GET, ie: cronjob.php?param1=param ...). These can add up pretty quickly. These just call system commands and run external programs (Nmap is one of them). They usually don't take long either. Anyway, can anyone tell me, roughly what point is too many? I know it's hard to say since it depends on what job is being run and how often, but at what point does the crontab program start "struggling"? Anyone have any idea? Thanks.
