• Ganglia and how it communicates

  - by MikeKulls

  I'm a little confused about how Ganglia sends information around and have found conflicting information on the web. I would have thought that the gmond process would either send info to gmetad at a regular interval or gmetad would request info from the various instances of gmond. At least one online article states this is how it works but from what I understand this is incorrect. It appears that you configure all gmond processes to send their info to a central gmond process and gmetad will request info from that central gmond. Is that correct? In my case I have 6 servers sending their information to 1 central server. If I set gmetad to get it's information from the central server then I get information from all 6 servers, all good.. Their weird thing is that if I point gmetad to one of the 6 servers then I still get info from all 6 servers. How is it that server 1 in my cluster if getting stats from all the other servers?

• Backing up Initial and Running configurations for Nortel Baystack 325-24G

  - by i.h4d35

  I recently came across a Nortel Baystack 325-24G switch. This is the first time I've come across a Nortel device of any sort, so I am a little intimidated. My problem is that I have been trying to get the startup and running configurations via both the CLI and the Menus but its become quite apparent that it isn't like the Cisco Switches/Routers. I've searched online but have only found Configuration Guides by Avaya. Also I'd like to know - is there a way to take backups regularly (something like tftp)? Pardon me but I'm a n00b when it comes to routers and switches. Thanks in advance.. EDIT: Still havent found a way to get the running config via the CLI

• sudo displays typed password in bash script

  - by Andy

  Hullo, I have a bash script that uses sudo a few times. There's a couple of strange points about it though. It asks me for my password a few seconds after I've already entered it for a previous command. The second time I enter my password, it's echoed to the display. Here's the relevant bits of the script. sudo service apache2 stop drush sql-dump --root="$SITE_DIR" --structure-tables-key=svn --ordered-dump | grep -iv 'dump completed on' | sudo tee "$DB_DIR/${SITE_NAME}.sql" > /dev/null sudo svn diff "$DB_DIR" | less sudo svn commit -m "$MESSAGE" "$DB_DIR" sudo service apache2 start The first password is to stop apache, and it works as expected. As mentioned, the sudo tee doesn't 'remember' that I have elevated privileges, asks for the password again, and echoes it to the screen. Given that tee is all about echoing to screen, I've played around a little with simple scripts which have | sudo tee, and they all work as expected. Ideas?! TIA Andy

• Keyboard with normal layout just without numpad?

  - by Pla

  Do you know any keyboard that does not have a numpad and, at the same time, is not a compact keyboard? I type a lot and I enjoy using standard full sized keyboards. I am annoyed by the presence of the numpad. I've never used it; it just wastes desktop space! All I could find are (even more annoying) compact keyboards. Sadly those keyboards are so compact that cram the arrow keys and the page up/down keys in a very little space. So, does anyone know a keyboard with a normal layout but without the numpad?

• Slow old notebook Hardy => Karmic

  - by Mailo

  Hi, i have one very slow notebook from year about 2000. On the computer is running icewm with firefox (in this times chromium for testing). My question is if it's good step to upgrade the system to Karmic Koala? I can't install another OS on that. It doesn't have CD-ROM, it can't boot from flash, or network. The new wanted state is little bit faster system for browsing web and copying photos to local NAS. I don't mention hardware configuration, becouse it's real speed is really deep below the paper parameters.

• Permanent Routes Centos Questions

  - by user65053

  So with a little help I figured out how to setup these routes and I can set them in rc.local route add -net 208.82.236.0 netmask 255.255.255.0 dev ppp0 metric 1 route add -net 208.82.236.0 netmask 255.255.255.0 dev eth0 metric 10 my question is being that the first route is ppp0 as soon as I disconnect the modem the route is dropped how do I maintain the route or make it permanent so that next time the modem connects it will follow the route. Currently after ppp0 disconnects the route is dropped netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface laxapx03.o1.com * 255.255.255.255 UH 0 0 0 ppp0 208.82.236.0 * 255.255.255.0 U 0 0 0 eth0 10.0.1.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 default 10.0.1.1 0.0.0.0 UG 0 0 0 eth0

• How do I set up DNS for an intranet web site?

  - by BradyKelly

  I have a web site running on our local server, 'OBAMA'. In my hosts file on that server, I map engenxt.local to 127.0.0.1, so typing engenxt.local on that machine itself brings up the website. I would like other machines to access the site via domain name 'engenxt'. On a Windows Server 2008 R2 Standard server, where would I begin, where should I go, and where should I end? I know precious little about DNS, or rather precious nothing, but am a quick study, besides, that is why I'm asking how to do this here. Episode 2 When I run DNS as Ryan suggests, it says 'the server OBAMA is unavailable. Do I want to add it?' It adds it, and tells me to choose to 'Configure a DNS server' from the actions menu, but nearly all the actions in that menu are disabled.

• public key always asking for password and keyphrase

  - by Andrew Atkinson

  I am trying to SSH from a NAS to a webserver using a public key. NAS user is 'root' and webserver user is 'backup' I have all permissions set correctly and when I debug the SSH connection I get: (last little bit of the debug) debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering DSA public key: /root/.ssh/id_dsa.pub debug1: Server accepts key: pkalg ssh-dss blen 433 debug1: key_parse_private_pem: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/root/.ssh/id_dsa.pub': I am using the command: ssh -v -i /root/.ssh/id_dsa.pub [email protected] The fact that it is asking for a passphrase is a good sign surely, but I do not want it to prompt for this or a password (which comes afterwards if I press 'return' on the passphrase)

• How to get started with tcp/ip v6?

  - by Johan

  Hi Now and then there is "news" about that the ip numbers will run out in X years, and we must change to tcp/ip v6... And even thou this crisis never really happens it has waken a question, how do you get started with tcp/ip v6? What can I do at home and is this a good or bad idea? Can you use IPv4 and IPv6 in the same cables in the same LAN, or do you need to physically separate them? Can you have some translation box so you can reach the "normal" internet from the IPv6 connected devices? (Just like a NAT-Router) Can someone please clarify the situation a little bit? Thanks Johan

• Tablet pen loses pressure sensitivity after screensaver

  - by Rohit Nair

  Tablet: Genius MousePen 8x6 System: Windows 7 64-bit The question says it all. When I first boot up my machine, the tablet works fine, with pressure sensitivity functionality. However, if I leave the machine long enough for the screensaver to start up, when I return, the tablet works just like a mouse, and does not respond to changes in pen pressure. Unplugging and replugging the device does not fix the problem. Disabling and enabling the device in device manager does not fix the problem. When I try to use the tablet config tool -before- screensaver, the pressure config works fine. It gives you a little area where you can draw to test out the pressure. When I try to use the same tool -after- screensaver, the moment I click on that drawing area, the config tool freezes.

• SharePoint 2010 Search - not search additional content sources

  - by Chris W

  I've got SP 2010 crawling a secondary intranet system that we'll run in parallel as part of a long running migration to SharePoint when it releases. Whilst it's crawling the pages without problem I can't see how to get the results to appear as part of the Quick Search results if the user does a search from the little search dialog box on the home page. Searches completed within a My Sites pages lists results from port the SharePoint installation and the external content source. Searches from the main search dialog only list results of SharePoint items. I tried adding the drop down option to select the site to search but this list only includes the name of the current site and doesn't offer an 'All Sites' scope option which I think would include the content. What am I doing wrong?

• Why DELL PowerConnect and Juniper are so rare ? Why do enterprises stick with Cisco ?

  - by Kedare

  Hello ! I have a little question, I'm actually studing IT in France, and when looking on alternative on the very [...] very expensive Cisco equipments, I've found Juniper and DELL PowerConnect pretty attractive on features and price, but I rarely see something else than the classics Cisco/LinkSys, HP Procurve and Netgear.. Why it's so rare to find those switch ? They looks really great but... I've never seen any Juniper or Powerconnect... Why do enterprises stick with the expensive Cisco ? I've tried to find how to buy both, it's quite easy with PowerConnect, everything is on the DELL website, but it looks it's very hard to find Juniper equipments in France :( Thank you !

• Bootstrapping in CloudFormation with Autoscale

  - by PapelPincel

  My CloudFormation template creates an autoscale group and bootstrap it with utility script /opt/aws/bin/cfn-init. When I remove the bootstrap part out of my template the, autoscale get created without any problem, but I add it the CloudFormation Stack fails and add line in /var/log/cloud-init.log : Error: AutoScalingGroupName does not specify any metadata The line above appens right after the following command : /opt/aws/bin/cfn-init --verbose --configsets orderedConfig --region us-east-1 --stack AS15 --resource AutoScalingGroupName --access-key XXXXXXXXXXXXX --secret-key XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Digging a little bit deeper, in cfn-init I added the following lines the point where it exit: from pprint import pprint pprint(vars(detail)) and I get the following trace when running the previous cfn-init command : {'_description': None, '_lastUpdated': datetime.datetime(2012, 7, 12, 14, 52, 42), '_logicalResourceId': u'AutoScalingGroupName', '_metadata': None, '_physicalResourceId': u'AS15-AutoScalingGroupName-HNPOXXXXXXXX', '_resourceStatus': u'CREATE_COMPLETE', '_resourceStatusReason': None, '_resourceType': u'AWS::AutoScaling::AutoScalingGroup', '_stackId': u'arn:aws:cloudformation:us-east-1:XXXXXXXXXXXXX:stack/AS15/XXXXXXXX-cc30-11e1-XXXXXX-XXXXXXXXXX', '_stackName': u'AS15'} As you can see, the metadata field is empty and that's the reason why it fails to create the stack. Is there any known side effects for cfn-init when used with autoscale ?

• How to convert PowerPoint presentations into a Kindle/E-reader friendly form?

  - by Shiki

  I have a lot of documents in .ppt and .pptx (blame the co-workers). I would like to read them on way home or elsewhere... when I have a little time to catch up with things. One thing I could do with the documents is cutting them together into one file. But saving that one even if a smaller version of PDF (according to Office 2010) results in a huge file. And PDF is hardly readable on a Kindle. I would need something .epub free, easy-on-the-device way. Is there such a thing? (Manually I could copy all the images down into native text and whatnot and create new presentations, save those, convert them. But that would just take a lot of time.)

• Quiet Sound while recording using the "Stereo Mix" option on Windows XP.

  - by DragoonX

  I'm trying to record some of my work, and the video capture program I'm using works fine. It's HyperCam2, and since it's not really professional, I don't care about that little thing in the corner. Anyways, If I check the record sound option and put it on the highest quality, and I want it to record the sounds playing from my computer, I have it record the "Stereo Mix" setting. However, after a quick test, I saw that even though my computer was at max volume, the recorded sound was very quiet, almost inaudible. Thinking it was just HyperCam, I downloaded Audacity, and only met similar results. While I'm not entirely savvy with hardware, I BELIEVE this to be my soundcard: SoundMAX Integrated Digital HD Audio

• Group Policy processing and autologon on Windows 7

  - by Jason Berg

  I'm trying to accomplish a few things via Group Policy on Windows 7. Software Installation, map drives, map printer, etc. I've got these computers set to autologon. The problem I'm running into is that the computers logon before DHCP has done its thing. Therefore, they don't apply any group policies properly. How do I fix this? I've already set a policy to "Always wait for the network at computer startup and logon". I've read up a bit and this doesn't actually mean that it waits for DHCP. So it's a little pointless. Anything that would delay logon would work. Or if I can somehow make the computer wait for DHCP.

• what software will rip a CD to flac files in one step?

  - by jcollum

  I'm using EAC to rip files to FLAC. Seems fine. But for a large amount of CDs (200 or so) the process is a little labor intensive. There's 4 or 5 clicks in there that seem extraneous -- EAC seems to want to rip the CD to a set of WAV files then (after all those files are ripped) I have to select "Process WAV files" (I'd get it exact, but EAC is occupied right now). I'd like to send all of it to FLAC files in just a few steps: get cddb info, select art, rip. Is there a way to do this with EAC that I'm missing? Haven't been able to find anything on the web that explains this. Is there a better program for this?

• Hosted version of Yahoo! answers [closed]

  - by Neil

  Hi all. Does anyone know of a hosted version of Yahoo! Answers (or Stackoverflow/Superuser) that I could integrate with my site? I know that there are some open-source implementations (see http://meta.stackoverflow.com/questions/2267/stack-overflow-clones?page=1&tab=votes#tab-top) but I'd rather have some hosted if possible. I know there is http://stackexchange.com/ as well, but I really want some tight integration with the rest of my site. Failing that, has anyone got any experience with the open source versions? Some of them look a little, erm, unfinished... Thanks. Neil.

• 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?

• Is opening ports in the firewall bad?

  - by Steven

  From what little I know about networking, opening ports lets external data get sent in. But how that data is handled is entirely up to the applications running on my machine. So if I'm not running any malicious applications, there should be nothing wrong with disabling the firewall, right? Also, how do applications work when ports aren't forwarded? For example, I need to forward port TCP 6112 to host Blizzard games, but I've heard that HTTP uses port 80, but I haven't forwarded that port, yet Firefox still works. Btw I'm using Windows Vista.

• How can I make the iTunes podcast count ignore selected podcasts?

  - by Relequestual

  Hi all, Until recently I have only listened to news type podcasts with people talking, like TWiT and Security Now. I also like music, so decided to subscribe to some other music related podcasts, however I don't want these to appear in my podcasts count in iTunes on the left hand side. I downloaded a load of old ones from the music related podcasts, and now I can't see at a glance how many news podcasts I have to listen to. I know it sounds really picky, but if it can be done, I would be a little bit happier. Of course I did some googling, but turned up a blank. Would guess it needs some form of plugin. Using the latest version of iTunes at the time of posting. Thanks in advance.

• Changing Recovery Model in Replicated Database

  - by Rob

  I now am the proud owner of two servers that replicate with each other. I had nothing to do with the install, but (of course), now i have to support the databases. Both databases are in the Simple recovery model, but the users want to ensure as little data loss as possible so I'm thinking that I should change the recovery model over to full and start doing transaction log backups. I wasn't planning on backing up the subscribing database, only the publisher. Is this the right plan? Do I need to switch both the Subscriber and and the publisher to Full, or can I leave the subscriber in Simple, but have the Publisher in Full? When I change the recovery model in one (or both) do the databases need to be offline? Thanks

• MacBook makes a noise from the MagSafe connection every time I flip a widget...

  - by Timmy

  OK this is bizarre. But basically, what happens is on my MacBook (latest model) whenever I 'flip' a Dashboard Widget I hear a little noise for the duration of the flip: like a tiny continuous squeak noise. It's quite strange. However, it only ever happens when the MagSafe cable is plugged in. WHY?! :'( The noise appears to me emitted from the MagSafe area itself, but, there's not any other CoreAnimation or Quartzey bits that cause this to happen, it only happens with Dashboard widgets... The noise is very quiet and you can only hear it in a silent room. Edit: Running the latest Snow Leopard.

• I would like to start multiple computers at once, What software do I use?

  - by Matt 'Trouble' Esse

  I have turned on Wake On Lan on all of the BIOSes in the PCs and I have a simple batch file that runs a free command wolcmd.exe Wake on Lan Command Line The syntax is as follows: wolcmd [mac address] [ip address] [subnet mask] [port number] The batch file looks a little like this.... wolcmd 009027a324fe 195.188.159.20 255.255.255.0 8900 wolcmd 009024a731da 212.86.64.31 255.255.255.0 8900 It's OK but It's not very user friendly (I need to set this up for other people to use and administer) Can you suggest a Windows (XP/Vixta/7) Alternative with a GUI? Free is cool, but a good paid for version is fine if you think it's worth it! Thanks in advance for your informed suggestions
