• 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?

• Vista to Vista network visability issue

  - by Sk93

  Hi All, I've got a Vista Business PC and a Vista Business Laptop connected via a virgin media router (Netgear CG2100D) and I cannot get the two machines to see each other correctly over the network. The laptop is connected via wireless, whilst the pc is wired. Both are set to recieve their network settings automatically (DHCP) and both have the windows firewall (the only firewall on either) turned off completely. I can ping each machine fine from one another using the ip addresses, and I can also connect via \. However, connections via \ fail, and I cannot see the machines in the network map. I have tried turning netBIOS to be "always on" on both adapters, but this makes no difference. I've been messing around pretty much for 6 hours now and am getting quite fustrated by this! (my original aim was to get media sharing working, but I've pretty much abandoned that for now). Any ideas?

• Intel hybrid graphics stuck in power save mode

  - by OZZIE

  I have an Asus UL30V with Intel hybrid graphics. When I bought it it used to switch to turn of the better graphics card to save power and run on a more power effecient one. When I connected the laptop to a power source again I could go to the intel graphics icon on the task bar and click on "switch to enhanced performance mode" or something similar. But like 2-3 months ago it suddenly vanished. I cannot switch modes anymore, it's gotten stuck in power save mode. I can change the windows power setting but that doesn't enable the better graphics card :( What should I do? I've tried restarting the computer and that does not work. I really hope I don't have to reinstall the drivers! It seems like other people have had the same issue: http://en.community.dell.com/support-forums/laptop/f/3518/p/19422695/19994601.aspx , he hasn't even got the same computer as me. I have windows 7 Home Premium x64 Any ideas?

• Any way to stop VMWare workstation from dropping SSH connections?

  - by oljones

  I have VMWare workstation 8 with a few Linux guests. I have had problems maintaining an active SSH connection to my VMs when they are in bridged mode. I first read that the onboard realtek network cards were not well supported so I bought a Intel Pro/1000 GT card. This supposedly had support. But this made no difference. Connections via SSH are active for about the first 3 minutes then hang and die. I have changed the TCP Checksum offload on the Intel and Realtek NICs, but this only works some of the time and even then not for very long. The best I could do was about 20 minutes before the connection was dropped. Any ideas?

• How much power supply do I need for my server, and could a shortage be causing my odd crashing?

  - by dolan

  I have 5 servers, all with similar hardware (i7, four 2tb 7200rpm drives, two 4tb 5400rpm drives, 430 watt power supply), and lately the machines have been freezing up. This has gotten worse in the last day or so, and I can't pinpoint any explanation. One recent change was adding the two 4tb hard drives. The crashes happen most often while running a large Hadoop job, so I was originally thinking the load was causing some issues, but last night one server just froze without any heavy load on the box (or so I think), other than HDFS (Hadoop's distributed file system) was probably rebalancing itself since two of the five nodes were offline. If I plugin a monitor and keyboard to one of these frozen machines, I can't get any response or feedback on the screen. Any ideas on possible points of failure and/or different logs I can look at to investigate? Thanks Edit: The systems are running Ubuntu 10.04 Edit 2: More on hardware: intel core i7-930 bloomfield 2.8ghz processor (quad core) 12gb (6 x 2gb) kingston ddr3 1333 ram antec earthwatts green 430 power supply msi x58m lga 1366 motherboard

• Yahoo toolbar and local sites (e.g. Intranet)

  - by Klaptrap

  We have local sites running on IIS in regular MS Windows network. User base has IE, FireFox and Chrome. Local sites are isolated by host headers and DNS record created for the common IP accordingly. This is a regular set-up. Users without Yahoo Toolbar type http://intranet and the sites resolves. Users with Yahoo toolbar type http://intranet and the toolbar goes off to search for this site in public domain. This is irrespective to whether the address is typed into the browser address bar or the toolbar. All versions of toolbar and IE are affected. I cannot see a setting on the toolbar to switch this "irritating" behaviour off and simply un-installing the toolbar is not an option. Any ideas?

• I hyperlinked a cell in excel 2003, formula issues?

  - by joseinsomniac

  I have a budget spreadsheet using excel 2003. I have My deposit, then all of my bills, the total, then a cell that has the difference(between the amount of deposit and the total of the bills). The difference cell numbers turn red when I dont have enough money (deposit vs bill total). I hyperlinked the difference cell to a checkbook register spreadsheet so I can track where all my extra money went(reconsile receipts daily). When hyperlinked the numbers are blue. I need the numbers to stay black(when above 0.00) and stay red (when the numbers are below 0.00) and not change after the link has been clicked on. Also if the link has not been clicked on, and the numbers are red, the font is smaller, even though the toolbar shows the font size hasnt changed. After I click on it and go back to the budget sheet, its the size it should be. Any Ideas? Thanks!

• why doesn't my computer resume after sleeping overnight?

  - by bamdad

  i'm having a weird, weird bug that's been haunting me since 11.10. if i listen to music or watch a video and my computer automatically goes to sleep at night, it won't properly resume in the morning. otherwise, suspend and resume works just fine. what happens is that the wi-fi and bluetooth indicator (that turns from white to orange when suspending) stays orange, the display doesn't turn on, and the only option i have is to hard reset the machine. here's what i've tried so far: installing (and uninstalling and reinstalling) laptop-mode-tools switching the proprietary wireless driver (broadcom-wl) to the open source one (brcmsmac & bcma) and back unloading (and blacklisting) all bluetooth modules (rfcomm, btusb, bnep, bluetooth) and stopping (# stop bluetooth) and disabling (# echo 'manual' /etc/init/bluetooth.override) the bluetooth service creating a custom pm sleep action as suggested here: http://ubuntuforums.org/showthread.php?p=11926504 not watching youtube / any stuff that uses flash before going to sleep (i have flashblock, and i checked $ ps aux | grep flash) because i suspected flash to be the culprit trying out different versions of fglrx (the one from the repos, then installing the latest one from amd's site via generated .deb files, then back to the official ones) none of these worked. i remember back in the days of 10.04, there was a gconf key called network sleep: i thought about disabling that, since re-enabling the wireless card seems to be the problem (according to the indicator led), but the option appears to be missing from gnome 3 (unity-2d, whatever). does anyone have any ideas? thanks, bamdad

• Why is Google Chrome making these weird requests?

  - by mackenir

  I noticed that now and again, Chrome will make three requests to weird hostnames that arent resolved. For example: HEAD http://gtblynlsos/ HTTP/1.1 Host: gtblynlsos Proxy-Connection: keep-alive Content-Length: 0 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.107 Safari/534.13 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Other example weird hostnames: http://nxibbjklov/ http://moheksgryj/ Has anyone else seen this? Any ideas what's going on? I have all Chrome extensions disabled.

• How to restrict access to a specific wireless network to only 1 user profile in Windows 7.

  - by Mathlight

  Hi all, I'm using Win7 SP1. I've got multiple users on the laptop that can / must connect to a wireless network, lets call it Wireless1. I've got an second wireless network, (lets call it Wireless2), which I want to limit access to only the admin user of the laptop. Now I can remove Wireless2 in the network manager every time, but i want a more user friendly solution, so that only the admin can connect to Wireless2, and all the other users cannot ( they may see the network, but must enter the password, like all other networks ). Any ideas?

• The 'which' command returns nothing via cron, but works via console

  - by Zárate

  Hi there, I've written a little utility in haXe + Neko that needs to execute some GIT commands. To avoid hardcoding the path to the GIT executable I'd like to use the which command to find out where it is. Everything works as expected when running manually from the console, but not when the the app runs on a cron job. I'm aware of the restricted environment (here or here) when you run a script using cron, but still surprised this doesn't work: /usr/bin/which git >> /home/user/git.txt The text file is created but the content is empty. Again, when run from the console it works as expected. Any ideas? I'm running OS X Leopard, if that helps. Thanks : ) Juan

• How to setup exchange server mail and address book accounts on mac - Snow Lepord?

  - by Abhishek

  I just got myself a mac, and I've been a long time windows user. So I'm exploring the built in apps, and I wanna setup my 3 mail accounts (1x gmail, 1x hotmail, and 1x corporate using google apps), but I want them to work the way they work on my iphone and my ipad - Using exchange... It really makes life easy to be able to receive and respond to mail instantly, not to mention the contact and calendar syncing... Any ideas? I have found the 'Exchange 2007' and 'Exchange IMAP' options when setting up the account, but things like the server address and all?

• Wired connection to windows ISC stopped working

  - by cmpickle

  I have had my Linux box connected to the internet through a Windows computer by wiring them together with a cat5 cable then the Windows is connected wireless to a router. This setup has worked since I got the Linux box but just yesterday stopped working. The changes that occurred were: I changed networking so that I was connecting the Linux box and Windows computer through a second router so during that time the Linux box went through a router to connect to the Windows computer that was still connected wireless to the first router. The Internet didn't work on the Linux box at the time they second router was involved when I removed it and directly connected the Linux box and Windows the Internet worked again. Another thing that changed was that I had disconnected my Windows computer from all network connections and deleted them to make my Ethernet work better. Also at that time my dad had I connect the Windows to a third router and changed some settings in it. After reconnecting this time the connection between the router and the windows would not establish. If anyone has any ideas as to why this is I would greatly appreciate it!

• Multiple users writing to one Samba mount point in OSX

  - by Sam

  I have an OSX box containing a script which writes a unique file to a Samba share. The first part of the script mounts the share. On the machine are 2 users- UserA and UserB. Each requires to run this script at any given time however only the user who mounted the share is able to write to it. I really need both users to have rwx access. Here is what I have tried: Mounting then chmod'ing the mountpoint (no effect- overruled by Samba server?) chmod'ing the mountpoint then mounting (same as above) sudo mount_smbfs Both users have admin privileges. Ideally a solution would be executable by one of the users (contained in the script) and not rely on mounting at machine boot time. Any ideas appreciated, thanks!

• Disabling monitor reconfiguration when closing lid

  - by Tomas

  I often need to move my laptop from one working place to another. When I do this, there are two events Ubuntu responds to by changing the monitor set up: Removing/attaching the VGA cable Closing/opening the lid of the laptop While removing the VGA cable gives me what I need (single screen, highest native resolution on the external screen if connected; otherwise highest resolution on the laptop), the laptop close/open lid response is not as good. Every time I close or open the lid, Ubuntu reconfigures the monitor set up. When I close the lid now... the screen goes black for a few seconds and it switches to clone, with my laptop screen disabled. Reopening results in... briefly a black screen, then the external monitor being used as desktop extension. Ubuntu thinks too much. My first and foremost question: Is there any way to let Ubuntu ignore lid close events? Ideally (or when there's no way to solve above question) I'd want to change how it deals with the screen reconfiguration. Why does Ubuntu toggle the screen configuration between external, clone and single display? Can't I just configure it to always use the external monitor, when present, in single screen mode? Note that similar questions have been asked before (most notably this one), but these have been closed perhaps wrongly. Any ideas are very welcome, I don't mind playing around a bit to see if something works.

• Enter / Return key stops working

  - by andygrunt

  I have a Dell Latitude E5400 laptop running Windows 7. Everything runs fine on it for days then I suddenly notice the enter/return key is no longer working e.g. I could be writing an email, press enter for a new line but it doesn’t ‘register’ – so no new line. I thought it might be some dirt under the key perhaps so I tried running the Windows onscreen keyboard but the Enter key on that doesn’t work either. A reboot always fixes the problem but it’s a pain. Any ideas a) how to fix it and b) out of interest, is there some other key combination that I can use as an alternative to using the Enter key when I need to? UPDATE: Thanks to CarlF's suggestion, I tried exiting running programmes and found it seems to be a problem with PhraseExpress.

• Corosync - stopping the service crashes the server

  - by Antipop

  I am trying to set up a test cluster on a Xen Server with 2 paravirtualized CentOS 5.4 machines. I am using Pacemaker+Corosync, and following the instructions found at http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf and other sites. Anyway, when I try to manually stop the corosync service, about 80% of the times the whole VM locks up with the message "Waiting for corosync services to unload" and I am forced to shut the machine down manually. For the remaining 20%, the VM keeps responding and adds dots to the above message, but it won't actually stop the service. There aren't many resources on the internet about this particular error. Any ideas about this? Thanks in advance.

• VGA resolution with Sony Bravia TV

  - by prestomation

  I just bought Sony Bravia KDL40S5100 tv. The VGA input is acting weird. I have a Gateway desktop with Windows 7 and Intel 945 graphics. I also have a laptop running Ubuntu 9.04. The TV will not display the gateway when the resolution is over 1360x768, I have to wait for it to time out and bring me back. The Intel driver even urges me to switch to the "recommended" 1920x1080. I just installed Win7 using this tv as the monitor. When the orginial welcome screen started after setup, it started me at 1080. I had to start in safemode to set a res that would work! When I plug my laptop into the TV, 1920x1080 works just fine. Any ideas? This laptop also has Win7, which I am going to try, but I haven't gotten a chance yet.

• How to exclude a sub-folder from HTaccess RewriteRule

  - by amb9800

  I have WordPress installed in my root directory, for which a RewriteRule is in place. I need to password-protect a subfolder ("blue"), so I set the htaccess in that folder as such. Problem is that the root htaccess RewriteRule is applying to "blue" and thus I get a 404 in the main WordPress site (instead of opening the password dialog for the subfolder). Here's the root htaccess: RewriteEngine on <Files 403.shtml> order allow,deny allow from all </Files> <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> I tried inserting this as the second line, to no avail: RewriteRule ^(blue)($|/) - [L] Also tried inserting this before the index.php RewriteRule: RewriteCond %{REQUEST_URI} !^/blue/ That didn't work either. Also inserted this into the subfolder's htaccess, which didn't work either: <IfModule mod_rewrite.c> RewriteEngine off </IfModule> Any ideas?

• IIS - Script for repeated hacks on a website

  - by dodegaard

  I currently have a site that is armored by ELMAH as its reporting mechanism. Each time someone hits a URL that is incorrect it notifies me or logs to the system. This is annoying for someone fat-fingering the URL with a misspelling but great when a hacker is trying to crack a site of mine. Has anyone ever written a script for IIS 7 on Win 2K8 that blocks an IP based on repeated attempts to hit a website? I've looked at Snort and other IDS systems but if I could get a script that could be linked to my ELMAH system it might be the perfect thing. PowerScript, etc. is what I was thinking. Hints and recommendations are wonderful and if you think a true intrusion detection system is recommended give me your ideas. Thanks in advance.

• I just recursively chmod'd everything under / to 750. Any tips?

  - by Ouairz

  I won't be the first and I won't be the last, I suppose. While playing around with the find command, I made a whoops and it would appear that instead of changing the permissions of the ~/web directory to 750, it changed the permissions of the entire filesystem (/) to 750, however I'm not certain, but any attempt to investigate is thwarted by Permission denied messages. For everything. This was the offending command: sudo find ~/web . type d -exec chmod 750 {} If I'm not mistaken, the Ubuntu team disabled root logins as a safety precaution so I'm out of ideas. I'm (obviously) a total newbie when it comes to file permissions so I was wondering if anyone had some good or even some bad advice to share. I've mentally prepped myself to losing everything on the computer which is only of mild consequence, since I have backups, but I did do a bit of work on this box over the week and it would be a shame to lose it all due to a boneheaded mistake. If you are reading this message, ask yourself, have you backed up any of your work recently? Thanks in advance for any insights. Feel free to scold me for using sudo carelessly

• How to diagnose a Windows XP hard crash

  - by Jon

  I have a 64-bit Windows XP machine which has hard crashed several times today. The symptoms are that the screen just goes blank, then the reboot cycle starts. There is no blue screen and even though it is switched on, no crash dump file is created. On all occasions it has happened during a period of high CPU/memory activity. I have run a full Dell diagnostics with no failures. Any ideas how to track this down further? Thanks.

• Costs/profit of/when starting an indie company

  - by Jack

  In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.
