• How to manage several Linux workstation like a cluster?

  - by Richard Zak

  How does one go about managing a lab of Linux workstations? I'd like for users to be able to log in, run their GUI apps (LibreOffice, Firefox, Eclipse, etc), and for the computers to be able to be used as compute nodes (OpenMPI). This part I'm fine with. But how can I centrally deploy a new software package or upgrade an installed package? How can I reload the entire OS on a given node, as if these workstations were part of a super computing cluster? Is there a nice program to help with setting up PXE booting and image management, and remotely managing packages? Ideally such a system would work with Ubuntu. If there isn't a nice package, how could this be set up manually?

• How can I automate my Linux computer to power off (and on preferably) under certain circumstances?

  - by Ashimema

  OK, So a little background; I've been using Windows Home Server as a Backup Appliance, Media Server and Share Server at home for some time. I decided it was costing me allot of juice so very early on added the "Lights Out" add-on to ensure it was only running as and when needed. I'm now looking to switch to a Linux based server and I'm looking for a similar tool/set of tools for advanced power management. Now the question; Anyone got any all-in-one suggestions (i.e with client parts for both Windows and Linux and a server part for the Linux server), or can anyone simply verify that I'll need to set-up all the individual bits for this myself separately? (A tool similar to "[SmartPower][2]" but for linux would be a great start)

• How to display password policy information for a user (Ubuntu)?

  - by C.W.Holeman II

  Ubuntu Documentation Ubuntu 9.04 Ubuntu Server Guide Security User Management states that there is a default minimum password length for Ubuntu: By default, Ubuntu requires a minimum password length of 4 characters Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)? > sudo chage -l SomeUserName Last password change : May 13, 2010 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 This is rather than examining various places that control the policy and interpreting them since this process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

• How can I toggle Full Screen mode in Remote Desktop without a Break key?

  - by Jay Bazuzi

  My small laptop has a small keyboard, which lacks a Pause/Break key. Ctrl-Alt-Break toggles Full Screen mode in Windows Remote Desktop. Without a Break key, how can I enter Full Screen mode? I know I can exit fullscreen mode with the mouse. Maximizing the window doesn't help. This matters more on small laptops because the screens are small (so you need all the real estate you can get) and because the keyboard lacks dedicated PgUp/PgDn and other dedicated keys (so I can't easily use the RDP alternatives like Alt-PgUp).

• How to disable text overwrite mode in Netbeans (CentOS)?

  - by Kevin Lee

  Everytime I type some text, it is overwriting what I have typed. I assume that the mode is set to overwriting, I want to insert the text not overwrite it, but I can't disable it because my insert key is mixed up with my delete key so everytime I enter insert to disable the overwrite mode, it just delete what I type. So how to disable this? I'm using centOS.. and it seems that my problem is only related to Netbeans because when I type here, it is set to insert mode.. but in Netbeans, it just overwrites the codes! help!

• How to install ported Linux software on a Mac? (MacPorts, Fink, anything better?)

  - by Ben Alpert

  On my Mac OS X machine, how would you recommend I install various software that's been ported from Linux? I don't install such software very frequently, but I've been using MacPorts and it always seems quite slow, presumably because it has to compile the packages on-the-fly. I'd much prefer a package management system that has binary packages, saving me the need to compile things every time I want to download something new. I think Fink has binaries for some of the packages, but I usually see MacPorts recommended as the system to use. Which do you think works better and why? (Or is there another system that I haven't heard of?)

• Finding Locked Out Users

  - by Bart Silverstrim

  Active Directory up to 2008 network (our servers are a mix of 2008, 2003...) I'm looking for a quick way to query AD to find out what users are locked out, preferably from a batch or script file, to monitor for possible issues with either user accounts being attacked by an automated attack or just anomalies in the network. I've Googled and my Google-fu has failed; I found a query off Microsoft's own knowledgebase that cites a string to use on Server 2003 with the management snap-in's saved queries (http://support.microsoft.com/kb/555131) but when I entered it, the query returned 400 users that a spot-check showed did NOT have a checkmark in the "Account is locked out" box under "account." In fact, I don't see anything wrong with their accounts. Is there a simple utility (wisesoft bulkadusers apparently uses this method behind the scenes, since it's results were also wrong) that will give a count of users and possibly their user object names? Script? Something?

• Easily manage vsftpd virtual users?

  - by Phil

  I have a vsftpd server configured with many virtual users. logins are stored in a Berkeley DB file One configuration file exists for each user to define his permissions (read-only or read-write, home directory, etc.). To do that, I use the user_config_dir parameter (set in vsftpd.conf). I am wondering if it would be possible to manage these virtual users from a simple GUI (such as web interface). I have found some tools but they are limited to generic vsftpd configuration, not virtual users management. Otherwise, PAM-MySQL seems to be a good way to manage users efficiently but only username/password and logs can be stored in database, not permissions. Finally, I've found this thread, but the solution is a bit awkward... Is there any way to easily manage the vsftpd users ?

• Lenovo tools for windows 7: can't re-enable wireless

  - by pcampbell

  Consider a netbook - Lenovo S10e with Windows 7 and the S10 Lenovo power management tools. Machine has factory BIOS. Fn+F5 is the key combo to toggle the wireless radio on/off. The tool allows the disabling fine; works as expected. The problem is that the re-enable doesn't work, or is confusing on how to re-enable. Previously tried without success: Fn-F5 Fn-Ctrl-F5 Fn-Shift-F5 Fn-Alt-F5 Here's the onscreen display: Question: How can you re-enable the wireless radio using the Function key on a Lenovo netbook?

• Close lid option "Do nothing" absent

  - by Jaap

  I just unpacked my new Sony Vaio, with windows 8 pro installed. Everything is nice, so I tried setting my power management options. The "When I close the lid" option only list: Hibernate Sleep Shutdown The "Do nothing" option is not present. I've seen loads of stuff on google where people ask or explain how to set this option to "Do nothing", but in all my power plans this option is absent... Can I use a tool to prevent this, or is there a way to force windows to show me this option (and that it actually works)? UPDATE powercf /q guid gives me this output: Subgroup GUID: 4f971e89-eebd-4455-a8de-9e59040e7347 (Power buttons and lid) GUID Alias: SUB_BUTTONS Power Setting GUID: 5ca83367-6e45-459f-a27b-476b1d01c936 (Lid close action) GUID Alias: LIDACTION Possible Setting Index: 000 Possible Setting Friendly Name: Sleep Possible Setting Index: 001 Possible Setting Friendly Name: Hibernate Possible Setting Index: 002 Possible Setting Friendly Name: Shut down Current AC Power Setting Index: 0x00000000 Current DC Power Setting Index: 0x00000000 Other sections have different enumerations where 000 stands for No action

• How to make a video card use DVI output by default in text mode?

  - by Igor Zinov'yev

  I have an ASUS ENGT440/DI1GD5 video card which has three outputs: DVI, D-Sub and HDMI. I am using both D-Sub and DVI, but my main monitor is connected to the DVI output. Everything works fine except for the text mode. The card somehow uses the D-Sub output in text mode when both monitors are connected (when I disconnect the D-Sub output and leave only the primary monitor connected to the DVI output, it's being used correctly). How do I make the card use only the DVI output (or both) in text mode?

• How to map command in vim that maintains mode when invoked?

  - by Phoenix

  I'm configuring vim in Mac OS X's Terminal app to do useful things with my arrow keys (among others). For example, I want option-left to move the cursor back one word, similarly to how it works in other Mac applications. In normal mode, this is easy enough; I can simply map the sequence to b. But when I'm in insert mode, I want to stay in insert mode (i.e., map the sequence to <c-o>b. In my .vimrc` file, I have these lines: nmap ^[[xol~ b imap ^[[xol~ <c-o>b Where ^[[xol~ is the character sequence that I've configured Terminal to send when I press option-left. This works, but it gets pretty tedious, especially when I've got nearly two dozen commands that I want to map. Is there a better way to do this?

• Ultimate way to use Picasa in a home network

  - by luisfarzati

  I've been trying a lot of approaches but still didn't find any effective solution. I want gigs of photos in a network drive (a IOMega Home Media Network Drive, plugged to my wifi router). I'd like to do 2 things: Do a Picasa import process of all the photos in the drive, making Picasa organize all the files in a year/month folder structure physically. Ideally, the import target directory should be the same network drive, otherwise I should move all the imported files in my local computer back to the drive myself. Share the Picasa database over the network, by uploading it to the network drive. Have me and other members of the family point our Picasas to the network database, and see the photos as well as make changes (tag faces, create logical albums, etc) into it. Is ANY possibility to accomplish this? Or should I be looking for another photo management app, and in that case do you know such one? Thank you!

• How to makesure VM is in Para virtualization mode on XEN?

  - by ananthan

  I am having a server running XEN,with ubuntu 12.04 as Domain 0. Intel VT is turned on by default and i dont want to run any Windows OS as VM. So 1. how can i makesure that all the created VM will be in paravirtualized mode even with VT enabled? I have heard that in Full Virtualization hypervisor needs to work hard for emulating all the underlying hardware,which may reduce performance for too much i/o specific applications when compared to para mode. 2.Since i am running only Linux VMs do i really need to enable VT support? 3.Can i be able to run Linux VM in para mode with VT enabled? 4.Will simply turning on VT support changes virtualization from para to full virtualization?? 5.Will there be any performance improvement for VM running Linux OS if VT is enabled?

• Windows 7 hangs after longer inactivity of user

  - by scooby37

  I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

• Is it bad to put your computer in sleep mode every time?

  - by Ivo Flipse

  Often I have a lot of stuff open and don't feel like shutting down my laptop, so I just use sleep mode when I'm transferring it. But I have no idea if this might have any disadvantages. So my question is: is it bad to put your computer in sleep mode every time? Things I'm wondering: Should I turn off my computer every once in a while? Will continuous use of sleep mode slow down my system in any way? Are there any bad side effects (in the long term)? Any thoughts? FYI I'm using Windows 7 on a laptop

• How do I determine if my controller is in IDE or AHCI mode in Linux?

  - by philcolbourn

  I have an old MacBook Pro 4,1 (early 2008) - but I suspect an answer would apply to many MacBook Pros. It has an Intel IDE/SATA controller (ICH8M/ICH8M-E). I have installed a patched MBR that is supposed to put my controller into AHCI mode. It does this by setting some controller port value that I don't understand. This seems to work as I get this from lspci: 00:1f.1 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03) 00:1f.2 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) SATA Controller [AHCI mode] (rev 03) Now most, perhaps all, sites that provide a solution (enabling AHCI) suggest that after a sleep/wake cycle that a controller will revert to IDE mode due to how Apple support Windows. They recommend disabling sleep. From author of patchedcode.bin I think Enabling AHCI for Windows on MacBooks NB: I do not have bootcamp installed and I do not have Windows installed. Is there a way to prove that my controller is in IDE or AHCI mode? Background Data Using patchedcode.bin MBR I get this in syslog: Jun 12 22:33:22 max kernel: [ 1.860955] ahci 0000:00:1f.2: version 3.0 Jun 12 22:33:22 max kernel: [ 1.861052] ahci 0000:00:1f.2: irq 45 for MSI/MSI-X Jun 12 22:33:22 max kernel: [ 1.861117] ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 3 ports 1.5 Gbps 0x1 impl SATA mode Jun 12 22:33:22 max kernel: [ 1.861120] ahci 0000:00:1f.2: flags: 64bit ncq sntf pm led clo pio slum part ccc ems Jun 12 22:33:22 max kernel: [ 1.861130] ahci 0000:00:1f.2: setting latency timer to 64 Jun 12 22:33:22 max kernel: [ 1.880880] ACPI: Video Device [GFX0] (multi-head: yes rom: no post: no) Jun 12 22:33:22 max kernel: [ 1.880983] scsi2 : ahci Jun 12 22:33:22 max kernel: [ 1.884552] scsi3 : ahci Jun 12 22:33:22 max kernel: [ 1.886932] scsi4 : ahci Jun 12 22:33:22 max kernel: [ 1.886998] ata3: SATA max UDMA/133 abar m2048@0xdb504000 port 0xdb504100 irq 45 Jun 12 22:33:22 max kernel: [ 1.887000] ata4: DUMMY Jun 12 22:33:22 max kernel: [ 1.887002] ata5: DUMMY Jun 12 22:33:22 max kernel: [ 2.204103] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Jun 12 22:33:22 max kernel: [ 2.204656] ata3.00: ATA-8: FUJITSU MHY2200BH, 0081000D, max UDMA/100 Jun 12 22:33:22 max kernel: [ 2.204662] ata3.00: 390721968 sectors, multi 16: LBA48 NCQ (depth 31/32), AA Jun 12 22:33:22 max kernel: [ 2.205324] ata3.00: configured for UDMA/100 Jun 12 22:33:22 max kernel: [ 2.205554] scsi 2:0:0:0: Direct-Access ATA FUJITSU MHY2200B 0081 PQ: 0 ANSI: 5 Using my original MBR I get this from syslog: Jun 13 18:07:13 max kernel: [ 0.622861] ata_piix 0000:00:1f.1: version 2.13 Jun 13 18:07:13 max kernel: [ 0.622869] ata_piix 0000:00:1f.1: power state changed by ACPI to D0 Jun 13 18:07:13 max kernel: [ 0.622924] ata_piix 0000:00:1f.1: setting latency timer to 64 Jun 13 18:07:13 max kernel: [ 0.623339] scsi0 : ata_piix Jun 13 18:07:13 max kernel: [ 0.623730] scsi1 : ata_piix Jun 13 18:07:13 max kernel: [ 0.623765] ata1: PATA max UDMA/100 cmd 0x8108 ctl 0x811c bmdma 0x80e0 irq 21 Jun 13 18:07:13 max kernel: [ 0.623767] ata2: PATA max UDMA/100 cmd 0x8100 ctl 0x8118 bmdma 0x80e8 irq 21 Jun 13 18:07:13 max kernel: [ 0.623810] ata_piix 0000:00:1f.2: MAP [ Jun 13 18:07:13 max kernel: [ 0.623811] P0 -- -- -- ] Jun 13 18:07:13 max kernel: [ 0.623866] ata_piix 0000:00:1f.2: setting latency timer to 64 Jun 13 18:07:13 max kernel: [ 0.624241] scsi2 : ata_piix Jun 13 18:07:13 max kernel: [ 0.624558] scsi3 : ata_piix Jun 13 18:07:13 max kernel: [ 0.624862] ata3: SATA max UDMA/133 cmd 0x80f8 ctl 0x8114 bmdma 0x8020 irq 18 Jun 13 18:07:13 max kernel: [ 0.624865] ata4: SATA max UDMA/133 cmd 0x80f0 ctl 0x8110 bmdma 0x8028 irq 18 Jun 13 18:07:13 max kernel: [ 1.208879] ata3.00: ATA-8: FUJITSU MHY2200BH, 0081000D, max UDMA/100 Jun 13 18:07:13 max kernel: [ 1.208882] ata3.00: 390721968 sectors, multi 16: LBA48 NCQ (depth 0/32) Jun 13 18:07:13 max kernel: [ 1.208961] ata1.01: ATAPI: MATSHITA DVD+/-RW UJ-867S, 1.00, max UDMA/33 Jun 13 18:07:13 max kernel: [ 1.216186] ata3.00: configured for UDMA/100 Jun 13 18:07:13 max kernel: [ 1.224396] ata1.01: configured for UDMA/33

• Spotlight on Oracle Social Relationship Management. Social Enable Your Enterprise with Oracle SRM.

  - by Pat Ma

  Facebook is now the most popular site on the Internet. People are tweeting more than they send email. Because there are so many people on social media, companies and brands want to be there too. They want to be able to listen to social chatter, engage with customers on social, create great-looking Facebook pages, and roll out social-collaborative work environments within their organization. This is where Oracle Social Relationship Management (SRM) comes in. Oracle SRM is a product that allows companies to manage their presence with prospects and customers on social channels. Let's talk about two popular use cases with Oracle SRM. Easy Publishing - Companies now have an average of 178 social media accounts - with every product or geography or employee group creating their own social media channel. For example, if you work at an international hotel chain with every single hotel creating their own Facebook page for their location, that chain can have well over 1,000 social media accounts. Managing these channels is a mess - with logging in and out of every account, making sure that all accounts are on brand, and preventing rogue posts from destroying the brand. This is where Oracle SRM comes in. With Oracle Social Relationship Management, you can log into one window and post messages to all 1,000+ social channels at once. You can set up approval flows and have each account generate their own content but that content must be approved before publishing. The benefits of this are easy social media publishing, brand consistency across all channels, and protection of your brand from inappropriate posts. Monitoring and Listening - People are writing and talking about your company right now on social media. 75% of social media users have written a negative post about a brand after a poor customer service experience. Think about all the negative posts you see in your Facebook news feed about delayed flights or being on hold for 45 minutes. There is so much social chatter going on around your brand that it's almost impossible to keep up or comprehend what's going on. That's where Oracle SRM comes in. With Social Relationship Management, a company can monitor and listen to what people are saying about them on social channels. They can drill down into individual posts or get a high level view of trends and mentions. The benefits of this are comprehending what's being said about your brand and its competitors, understanding customers and their intent, and responding to negative posts before they become a PR crisis. Oracle SRM is part of Oracle Cloud. The benefits of cloud deployment for customers are faster deployments, less maintenance, and lower cost of ownership versus on-premise deployments. Oracle SRM also fits into Oracle's vision to social enable your enterprise. With Oracle SRM, social media is not just a marketing channel. Social media is also mechanism for sales, customer support, recruiting, and employee collaboration. For more information about how Oracle SRM can social enable your enterprise, please visit oracle.com/social. For more information about Oracle Cloud, please visit cloud.oracle.com.

• Are VMWare ESXi 5 patches cumulative?

  It seems basic, but there's confusion about the patching strategy needed to manually update standalone VMWare ESXi hosts. The VMWare vSphere blog attempts to explain this, but it's still not clear. From the blog: Say Patch01 includes updates for the following VIBs: "esxi-base", "driver10" and "driver 44". And then later Patch02 comes out with updates to "esxi-base", "driver20" and "driver 44". P2 is cumulative in that the "esxi-base" and "driver44" VIBs will include the updates in Patch01. However, it's important to note that Patch02 not include the "driver 10" VIB as that module was not updated. Many of my ESXi installations are standalone and do not make use of Update Manager. It is possible to update an individual host using the patches make available through the VMWare patch download portal. The process is quite simple, and that part makes sense. The bigger issue is determining what to actually download and install. In my case, I have a good number of HP-specific ESXi builds that incorporate sensors and management for HP ProLiant hardware. Let's say that those servers start at ESXi build #474610 from 9/2011. Looking at the patch portal screenshot below, there is a patch for ESXi update01, build #623860. There are also patches for builds #653509 and #702118. Coming from the old version of ESXi, what is the proper approach to bring the system fully up-to-date? Which patches are cumulative and which need to be applied sequentially? Perhaps the download size is the confusing factor, but is installing the newest build the right approach, or do I need to step back and patch incrementally?

• How to use Salt Stack with minions all behind NAT (not publicly accessible, default salt ports not open)?

  - by MountainX

  Can Salt Stack minions communicate with the salt master from behind NAT/Firewalls, etc., using standard ports that would be open be default in all consumer NAT routers (and without the minions having a public DNS record or static IP)? I'm working my way through my first salt tutorial, and this is where I'm stuck. I am able to configure iptables on the Ubuntu salt-master. But I have no control over the routers/NAT that the minions will sit behind. So far I tried these settings: /etc/salt/master: publish_port: 465 ret_port: 443 /etc/salt/minion: master_port: 465 That did not work. Background: I have a custom developed application presently running on about 40 Kubuntu laptops (& more planned). Every few months I have to update the application. (Often this just amounts to replacing a .jar file, which requires root permissions.) I also have to run Ubuntu updates and a few other minor things. I've been doing it manually, one by one, using Team Viewer to log into each client. I would like to dramatically improve this process. The two options I'm aware of are either: use reverse ssh tunnels and bash scripts. I tested this and it works. But I don't get any of the reporting, etc., I would get with Salt Stack. use Salt Stack (or similar) management tool. But I need a really simple tool. I can't invest any time in a big learning curve. I looked at Puppet and a bunch of related tools. The only one I found that looked simple enough for me (so far) was Salt Stack. But I'm stuck now because my minion can't reach the salt-master, as stated above. I appreciate suggestions.
