• SSO solution and centralized user mgmt for about 10-30 Ubuntu machines?

  - by nbr

  Hello, I'm looking for a clean way to centralize user management. The setup: About 10-30 linux machines (Ubuntu 10.04 LTS server) Maybe 10-30 users for now. The requirements (hopes and expectations): A single place for the administrator to manage user accounts, passwords and the list of machines each user has access to. (And probably groups.) Doesn't have to be fancy. Single sign-on for SSH: the user should be able to login from machine A to machine B without re-entering his/her password. A Quick Google searches give me pointers to OpenLDAP and Kerberos, but I'm not sure where to start and what problem will each solution actually solve. Which way to go? I'd love to find a clear that focuses on this subject. (Or: am I asking "a wrong question"?)

• Will restarting the W3SVC Web Publishing Service, also restart the app pool in IIS?

  - by Mark Rogers

  Background: I'm trying to stop and start IIS on a windows 7 build box, in order to run acceptance tests. But from what I have read, most of the remote web management features have been disabled by Microsoft in a retarted attempt to sell more Windows Server 2008 licenses. Still for some reason they didn't disable the least user-friendly ways of controlling IIS remotely, but they are all a total pain. What I can do easily is remotely stop and start the WWW service from a msbuild task. But I want to be sure that this also restarts the app pool, so that when I copy in new web files the web server there will be serving the most recent version of the website. Question: If I restart the W3SVC windows service, will that also restart the app pool?

• Extremely slow startup of tomcat

  - by Henrik

  I have a tomcat 7 installation on a Solaris 10 server. My problem is that starting the server (or deploying a new war) is extremely slow. It usually take 30 - 60 minutes. The war application is a medium sized grails application so there are quite a a lot of files. The server is running other server applications as well but from my basic skills I don't see this as a problem. Can anyone give me some tips on how to analyse this? Settings in Tomcat, java, server, disc access or something else? I use these parameters to tomcat: CATALINA_OPTS="-Dcom.sun.management.jmxremote=true -Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=512m -XX:MaxPermSize=512m -XX:+DisableExplicitGC" And I use a 32 bit java 1.6.

• Can I run my MacBook in clamshell mode without being connected to power?

  - by kch

  Hi, At home, I run my MacBook in clamshell mode (closed lid, external display). This works fine when you're connected to the power adapter, but it doesn't work when running on battery. That's how it's supposed to be and Apple has some kb entry on the issue. But it's also lame. You can prevent the machine from sleeping when closed by running InsomniaX, but then it'll assume the builtin display is still active, so you end up with a two-display setup when you really only want the external. This is obviously less than ideal. So, is there any work around, hack, utility, black magic that I can use to make it run in clamshell mode while strictly on battery power? Also, bonus points for a solution that makes the AC status not affect the machine state at all. (Like, you know, it does normally, when not in clamshell.)

• How to setup Wordpress High Availability

  - by Ketam

  I have installed Galera Cluster on 3 cluster + 1 management. I wanted to make it like this, Server1: Home (www.domain.com) Server2: For BBpress/Forum (Forum Tab Menu will forward to forum.domain.com) Server3: BuddyPress Activity (Social Tab Menu will forward to social.domain.com) The purpose I am doing this is to distribute my resource and load balancing each other at same time. However, I have difficulty to setup Apache Load-Balancing/mod_proxy/clustering or any suitable to have high availability WordPress. Any best suggestion/solution to make high availability WordPress? Or how to? And another question is I tried to copy whole WordPress files & folders to Server2 connecting to local database (same data inside since it is already on Galera Cluster) but the page blank. Any advice? OS: Centos 6.2 Thanks in advanced.

• How to set up Drupal Plugin Manager on MAMP in a secure way?

  - by Andrei

  Hi, I use MAMP PRO as global webserver. First of all, is it a good idea? Secondly, my objective is to run a Drupal website with as easy management as possible. Now I want to use Plugin Manager module to install additional modules and themes for my website. It wants to use ftp for that, and I know that if I open access to FTP port then IT-department guys will come to me and ask to shut it down. So I wonder if there is a way to allow Plugin Manager to install modules, having the port 21 closed somehow?

  I am trying to use the feature "Create a Report in Microsoft Excel" for Visual Studio TFS 2010. I am being prompted for a username and password in Excel for any given Team Project when right clicking the item "Active Tasks", selecting "Create a Report in Microsoft Excel," found in the following path within the Team Explorer pane, from Visual Studio 2010: 'Collection Name' | 'Project Name' | Work Items | Iteration 1 | Active Tasks I am a Team Project Administrator and Collection Administrator. I checked The SharePoint site: http :// 'serverName'/Reports/Pages/Folder.aspx and have full sitewide and project permissions on this site. I loaded SQL Server Management Studio on the machine running the instance of TFS (and also the SQL backend for TFS) and ensured that I had roles "serveradmin" and "sysadmin". How do I run this report? Specifically, what permissions are required?

• VMware ESX 3.5 Host Health shown as unknown

  - by dunxd

  I have an ESX 3.5 update 5 cluster of five host servers, all fully patched as of this Friday. Today I noticed that one of the servers has the Hardware Health status as unknown in Virtual Center Infrastructure Client. When I look at the Health Status view under configuration for that host, all the items are status Unknown. The server is exactly the same configuration as the others - same model (HP DL360 G5), memory, NICs etc. I have tried restarting the management service with service mgmt-vmware restart but this has not resolved the issue. Asides from this, I am not seeing any issues with the cluster - however, I hate having a blind spot like this. Any ideas?

• Leave Windows Session Logged On

  - by Kyle Brandt

  Is a bad idea for any reason to leave accounts logged onto Windows remote desktop sessions? So instead of logging off, just closing the session so it locks. In this case, the limited number of remote desktop connections is not an issue. I am just wondering if anyone has seen sessions leak memory over time or maybe security issues with doing this, etc... I could see if programs were left open they might suck up and or leak memory, but has anyone seen this with Microsoft software such as Control Panels, Management Consoles, and Exchange System Administrator?

• TORQUE: Find out why the job is queued?

  - by ahmad

  Under TORQUE-MAUI job scheduling system, there are several reasons to have a job stayed in Q state. Those that I know are: There are not enough resource to run the Queued job. The user is not allowed to have further running jobs. The user is not allowed to have further computation cores. Is there any other reason to have the queued job? Further information: I am asking the question because I have couple of queued jobs while some nodes are free, pbs_mom is on on them, and mauid limitations are generously large. Thanks in advance.

• Error in New-MailboxExportRequest - "Couldn't find the Enterprise Organizational Container" even though permissions seem right

  - by tacos_tacos_tacos

  When disabling users I typically will be asked to retain a copy of their mailbox. I accomplish this by literally creating their mailbox in Outlook and then exporting to PST. Is there some way around having to do this just to save a mailbox? Edit: I've tried New-MailboxExportRequest but I keep getting the following after providing an alias: Supply values for the following parameters: FilePath: \\localhost\EXPORT_PST\myuser.pst Mailbox: myuser Couldn't find the Enterprise Organization container. <--- the error I've also tried supplying [email protected] as the mailbox as well. Edit 2: I had already seen the post at http://www.mikepfeiffer.net/2010/10/error-couldnt-find-the-enterprise-organization-container-when-creating-a-new-mailbox-export-request/ so I set the permissions as follows below: NTFS permissions Sharing permissions I am still getting that error. Final Solution In Exchange SP2, it does not warn you that you have not set role assignments, it just fails. So be sure to create a management role for "Mailbox Import Export" and add your user to the group, then restart PowerShell for this to take effect.

• How to fix unstable RJ45 jacks? [closed]

  - by BeemerGuy

  This is a little project I'm doing at home. I wanted to wire two rooms together (basically, the router is one room, and the switch is in the second room). So I ran a CAT5 between the two rooms, and wired an RJ45 jack in each room. I then hooked up the two jacks with two CAT5 cable to run it through the cable tester, and all 8 wires seem good. Now, when I connect the switch and the router, the connection is unstable -- I ping the router and it barely holds on for two pings before it disconnects, and stays in that unstable state. Just to make sure the router and the switch are ok, I connected them with long wire between the two rooms and the connection is absolutely stable, and pings continuously. What could be the cause for the unstable connection? Especially that it pings a few times, so there IS a connection. But why is it unstable? And how come the cable tester says it's ok, but it's unstable?

• Web Filter For Multiple Networks

  - by Rob

  I have been using a Barracuda web filter 310 in our network and I have just had enough of it. It does not support trunking and we have several networks that have users that need to be web filtered. (I guess if everyone just did their flippin jobs I would not have this issue) but the management wants me to get it resolved. Does anyone know the top five web filters that are better than the barracuda web filters that support network trunking so that I can have multiple domains and subnets going through it? Thanks in advance - everyone on this site is gold in my book!

• What does an ACPI BIOS configure during boot?

  - by RJSmith92

  When a PC boots with an ACPI BIOS, what does it exactly do? I understand that the point of ACPI is to allow the OS to control hardware resources and power management but before the OS is loaded does ACPI configure just the devices needed to boot and then let the OS configure the rest? If the OS wants to re-asign hardware resources does it store this information in the ACPI tables so that the next time the system is booted it assigns them how the OS wants? The ACPI driver asks the PCI bus driver (Pci.sys) to enumerate devices on it's bus once the OS is loaded, how are these devices configured whilst the PC is booting when it doesn't have other bus drivers? Any help with any of the above questions would be greatly appreciated. Thanks.

• How to set Laptop Brightness in Gnome and /proc on Thinkpad W510?

  - by hakre

  I can set the brightness of my laptop screen already via /proc. I can read and change the value. Now I've set the value to 33 and then I went into gnome power management and enabled the option that it should reduce the backlight brightness being on battery. That works, the screen gets darker. If I now read out the current setting from /proc it still says it's 33. So I assume that there is another node in /proc to be used to control the brightness. The node I use so far is: /proc/acpi/video/VID/LCD0/brightness I'm using the nouveau driver. With the nvida driver the brightness can not be controlled.

• Hyper-V and host-installed hardware devices: can guest VMs access?

  - by gravyface

  Have a couple of servers I'd like to setup as Hyper-V Servers, with a couple of Windows 2008 Standard VMs. On the host, we have a few hardware devices we'd like to be accessible to the guest; I'm not sure if these are supported via a raw "pass-thru" on Hyper-V (which I don't have alot of experience with) if the same drivers are installed on the guest. Hardware in question is a Brooktrout fax card, a SCSI adapter for the tape drive, and a 9-pin serial connected to one of the core firewalls for management.

• Windows 7 on 1st Gen MacbookPro Unibody (Q4-2008) - power problems.

  - by typemismatch

  I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

  Hi, I want to make sure that certain users are available in a group from the windows domain. I installed "Group Policy Management" and can open the Forest, the Domain.

Any possibility to find out anyway?

• How do I pick a motherboard?

  - by EpsilonVector

  When building your own computer one part was always a mystery to me: the motherboard. Picking a CPU/GPU/memory is easy- you just figure out where the various chips are in the low end to high end scale, do a little market research on what current games demand, and pick the parts from their respective continuums of low-to-high-end models. A mother board is more complicated though. Its features are not as obvious as "this motherboard is faster than that motherboard". Now you need to deal with part compatibilities, bus speeds, maybe power management stuff, etc. I'm interested in a short guide for selecting a motherboard, especially- what pitfalls to avoid (for example, can bus speed become a bottleneck?). To clarify: I'm not looking for motherboard recommendations. I'm looking for guidance regarding how to evaluate the fitness of a motherboard given the rest of the computer parts.

• Enable/disable wireless interface in a bat file

  - by Herms

  Is there a way to enable/disable a wireless network interface via the command line (so I can put it in a bat file)? When I'm in the office I use a wired connection, but Windows still occasionally bugs me about my wireless connection not being connected (even though I turned off the option for notifying me when there's no connectivity). I'm guessing the only way to stop it from bugging me is to disable the interface, but I'd rather not have to go into the network settings every time I need to do so. I'd like to set up a bat file or a shortcut that I can use to enable/disable the wireless (preferably a single one that toggles the current state), and then just set up a keyboard shortcut for that. I just have no idea how to do so from the command line.

• DVI-D Splitter Not Working with GeForce 8400gs

  - by jimdrang

  I have a GeForce 8400gs and it has a DVI and VGA port on the back. I was using dual monitors with one VGA and one DVI cable. I wanted both displays to be digital so I bought a DVI-D splitter and put one DVI cable in each monitor, connected them to the splitter and put the single merged connection in the back of the cards DVI connection. It will not recognize the second monitor (I'm not even sure how it determined which one was the first monitor). The tech specs state that it supports "Two dual-link DVI outputs for digital flat panel display resolutions up to 2560x1600" http://www.nvidia.com/object/geforce_8400_tech_specs.html. Do I need a different converter or is my only option for dual monitors with this card one VGA, one DVI?
