• Cannot Install Bootcamp on Mac Fusion Drive

  - by user3377019

  I have two drive installed in my mid-2013 Macbook pro. It is running osx maverick. I set the two drives (an ssd and a regular HD) up using the fusion drive (following the diy fusion drive guides out there). I went ahead and created a 40gb partition to host my windows install. I removed the SSD, installed windows, then reinstalled the SSD. As soon as the ssd was placed back in the bootcamp partition stopped booting. I get a blinking cursor on a black screen. I checked out the partition info in disk utility and it appears that the windows partition is not marked bootable. Below is some info I managed to gather. I am wondering if there is a way to fix the partition table so my bootcamp will boot. /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage 119.7 GB disk0s2 3: Apple_Boot Boot OS X 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: EFI EFI 209.7 MB disk1s1 2: Microsoft Basic Data BOOTCAMP 40.0 GB disk1s2 3: Apple_CoreStorage 459.2 GB disk1s3 4: Apple_Boot Boot OS X 650.0 MB disk1s4 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD *573.4 GB disk2 Name : BOOTCAMP Type : Partition Disk Identifier : disk1s2 Mount Point : /Volumes/BOOTCAMP File System : Windows NT File System (NTFS) Connection Bus : SATA Device Tree : IODeviceTree:/PCI0@0/SATA@1F,2/PRT1@1/PMP@0 Writable : No Universal Unique Identifier : 584BAED6-4C46-4F18-93B3-957F6E27003C Capacity : 40 GB (39,998,980,096 Bytes) Free Space : 16.34 GB (16,339,972,096 Bytes) Used : 23.66 GB (23,659,003,904 Bytes) Number of Files : 86,424 Number of Folders : 0 Owners Enabled : No Can Turn Owners Off : No Can Be Formatted : No Bootable : No Supports Journaling : No Journaled : No Disk Number : 1 Partition Number : 2

• WT-NMP - PHP-CGI randomly stops running with no error log

  - by alexfontaine

  We have recently installed WT-NMP and are currently running Php-Cgi with php 5.4.24. We are running fairly simple php scripts and when testing everything is running fine. Over the weekend we wanted to keep the server running test it over a longer period of time. The server and scripts ran fine all day on Friday, but sometime late on Saturday, the php-cgi stopped running. There are no errors in the error log (C:\WT-NMP\log). In the configuration (php.ini) I have the following options set: error_reporting = E_ALL display_errors = On display_startup_errors = On log_errors = On html_errors = On error_log = "c:/wt-nmp/log/php_error.log" We also have the standard nginx.conf error logs: access_log "c:/wt-nmp/log/nginx_access.log"; error_log "c:/wt-nmp/log/nginx_error.log" warn; So, since the log directory is empty, I am assuming that the running php scripts and general nginx operations are not causing the php-cgi to stop. So my questions are: What else could cause the php-cgi to stop running? Are there any other options for logging that we could turn on that could help us track this down? Are there other log locations that we should be looking at? Thanks!

• Connecting to server from remote machine

  - by Jannat Arora

  I wish to connect my machine to a server in some other city. For doing the same I am using the following command: mstsc -v ip_address_of_server remote desktop can't connect to remote computer for one of these reasons: 1) Remote access to server is not enabled. 2) Remote computer is turned off 3) Remote computer is not available on network. Make sure remote computer is turned on and connected to the network, and that remote access is enabled. As per previous posts I need to turn off my client computers firewall..which I have...but still it gives me the same message. Can someone please please help me out...so as to how i may resolve this?? I am really new to networking, etc. Also when i am pinging: ping ip_address_of server I am getting the following response: Reply from ip_address_of_server: destination host unreachable Also I did try on ubuntu with rdesktop...still its not been able to connect with it. Also i know there are other people who are able to connect their machines with the server remotely. So i guess its not working for me only. Also when I accessed the same machine through LAN I was able to do so.

• Google Maps mashup for notes/househunting

  - by afray

  I'm house-hunting at the moment and I'm trying to geek it out er I mean streamline the decision-making process. I'm currently using google maps's "my maps" feature to store pins to properties. I create one map per estate agent, then put relevant into into the individual pins. The idea being, I can look at the map and quickly choose which property to view next. However the pins don't currently link back to the map they're owned by, so you have to hunt a bit to get the estate agent info, it's a hassle to get all maps displayed in a new session if you have lots of agents, and each pin doesn't automatically show its bubble so you have to do lots of clicking to see all the info you want. I've tried Evernote, but despite its tag system initially showing some promise, I can't find a way to seemlessly integrate maps. A few google searches don't turn anything up either. Even the big sites, like http://www.rightmove.co.uk, don't seem to provide any maps integration by default. You can see an individual house's location, but not all results of a search. So is there a web site or windows program I could use to do something like this? Viewing all properties on a map is a must, as is quick access to contact details.

• How to set up QoS on ADSL router (terracom) for prioritizing browsing

  - by DBZ_A

  I want to configure the ADSL router which connects 10+ machines to the internet. I want to give maximum priority to browsing (ports 80,443) and set low priority for bittorrent etc.(port 42180) I have been experimenting with settings , but with no luck. There are three settings which confuse me, along with my understanding. 802.1 Priority - Related to LAN level, possible values 0-7 , higher numbers means higher priority. 'Mark traffic priority' - clueless about this. IPP/DS - IP Precedence - possible values 0-7 ; 6 & 7 are reserved, so set 5 for highest priority. Or when using DSCP - set 46 for highest priority. Please help me in getting this done... Similer question for another model of router here , but with less number of confusing options :) How to configure QoS on home router Update: from discussion on another thread, QoS can control only upstream traffic (from router to the internet) , while this may in turn affect downstream traffic rate, there is no direct control over data coming into the router.

• What breaks in a Windows domain if a member has a high time skew?

  - by Ryan Ries

  It's taken for granted by most IT people that in a Windows domain, if a member server's clock is off by more than 5 minutes (or however many minutes you've configured it for) from that of its domain controller - logons and authentications will fail. But that is not necessarily true. At least not for all authentication processes on all versions of Windows. For instance, I can set my time on my Windows 7 client to be skewed all to heck - logoff/logon still works fine. What happens is that my client sends an AS_REQ (with his time stamp) to the domain controller, and the DC responds with KRB_AP_ERR_SKEW. But the magic is that when the DC responds with the aforementioned Kerberos error, the DC also includes his time stamp, which the client in turn uses to adjust his own time and resubmits the AS_REQ, which is then approved. This behavior is not considered a security threat because encryption and secrets are still being used in the communication. This is also not just a Microsoft thing. RFC 4430 describes this behavior. So my question is does anyone know when this changed? And why is it that other things fail? For instance, Office Communicator kicks me off if my clock starts drifting too far out. I really wish to have more detail on this. edit: Here's the bit from RFC 4430 that I'm talking about: If the server clock and the client clock are off by more than the policy-determined clock skew limit (usually 5 minutes), the server MUST return a KRB_AP_ERR_SKEW. The optional client's time in the KRB-ERROR SHOULD be filled out. If the server protects the error by adding the Cksum field and returning the correct client's time, the client SHOULD compute the difference (in seconds) between the two clocks based upon the client and server time contained in the KRB-ERROR message. The client SHOULD store this clock difference and use it to adjust its clock in subsequent messages. If the error is not protected, the client MUST NOT use the difference to adjust subsequent messages, because doing so would allow an attacker to construct authenticators that can be used to mount replay attacks.

• Get rid of gray brackets arond editable text in restricted Word docs

  - by Brendan

  I'm trying to work out a problem in Word that I thought was simply a glitch from 2003 until we upgraded to 2010 and the problem persisted. For our corporate letterhead, we set up the template with placeholder text, highlight the text, and then make the document read-only with the exception of the selected text. The editable text turns yellow and gains these brackets around them: Once these brackets appear, they'll always show on the screen. That I can handle, though I'd like to learn how to hide them on-screen if that's possible. When the document is printed while protected, it works fine. When the document is printed while NOT protected, part of the bracket shows up on the paper! I guess the ultimate question is, how can I get rid of the brackets altogether? I can see why they exist but in my use case they create more problems than they solve. I'd like someone to be able to read the doc without seeing brackets, and I'd like other people in my department to be able to print without having to re-restrict it first. I tried to turn off bookmarks because that's what seemed to come up when I searched around, but that didn't do anything.

• Network share not always available on Windows 2003

  - by JP Hellemons

  Hello everybody, we have a windows 2003 server with a shared directory/folder. I've seen this thread but this wasn't any help: http://superuser.com/questions/58890/the-specified-network-name-is-no-longer-available I have a ping -t running from 3 pc's (vista and two windows 7) they all work. the problem occurss when two users enter the network share then this 'network share is no longer available' appears and the explorer windows turn white. after f5 or refresh the shared directory is back. this is really strange. there is no anti virus or kasparsky running on either end. this is all in the same LAN. the internet connection is really stable, so it's really strange. because a stable internet connection should imply that the local network connection is also stable and that this is a windows issue. can it be a router issue? I have checked the eventlog on the server for diskfailure related messages, but there are none. EDIT: can this be related to mapping a shared directory to a drive letter? and that there is a router between me and the mapped network drive? or is it just windows that is not working well with two users on the same shared folder? should I install samba or something?

• Shared printer stops working on clients but not host computer

  - by Tony

  I have a Brother MFC-7420 USB all-in-one laser printer. It is plugin via USB to my Windows 7 x64 machine. I have it shared to a few users on my home network. My wife's laptop running Vista x64 can normally print fine to the printer. However it seems that every day or two, when she pushes print on a something it just sits in her laptop's print queue and never makes it to my desktop. The only thing that seems to fix this is if she restarts her laptop. Not a big deal but this problem is sort of annoying. I don't know if this affects but the laptop is put into hibernate at night and I turn my desktop off at night. Does anyone know why this happens and if there is something easy to do to fix the problem besides restart the computer? EDIT: I was thinking that maybe my wife's laptop loses its connection to the printer. Is there a way to reset a connection to a shared printer? Or maybe reauth with the printer?

• How to let MSN or Yahoo Messenger set you to be Invisible or Offline when you are idle for an hour?

  - by Jian Lin

  The short question is: How do we let MSN or Yahoo Messenger set us to be Invisible or Offline when we are idle for half an hour or an hour? The reason is: if I am on 24 hours a day, some people see me as weird. Some people see my value as low, because I am always there. There are ways to set me to "Away" or "Busy" after 10 minutes, but there seems to be no way to set myself to invisible or offline after 1 hour. As I am a software developer, I am very used to turning the computer on 24 hours a day. (for example, for checking email for urgent fixes, and fix issue and push to web server). We don't turn off computer usually even when we sleep, because we may sometimes can't sleep yet and come check on the computer, or wake up in the morning and immediately need to check if everything is ok. But, my MSN and Yahoo Messenger is always on for 24 hours a day, and I found that some girls start to ask me why I am always there 24 hours a day (even though they see me as away or busy, their feeling is that I am always there). What's more, I found that since I am always there, my value actually drop in their eyes, because hard to get = high value, and always there = low value. Some people feel me as having nothing much to do, always in front of computer, or what is he doing in front of computer so much? Now since it is my job, and I need to read emails once in a while, I am in fact in front of the computer more than some other people. I am in front of the computer maybe 10 hours a day, far from 24 hours a day. Is there an easy and automatic solution to this?

• Perl EPIC Not recognising installed CPAN modules

  - by Recc

  Eclipse on a mac, was working fine adding new modules until I Installed Text::CSV_XS which Eclips doesn't recognise as added to @INC For instance use strict; use SOAP::Transport::HTTP; SOAP::Transport::HTTP::CGI->dispatch_to('C2FService')->handle; BEGIN { package C2FService; use vars qw(@ISA); @ISA = qw(Exporter SOAP::Server::Parameters); use SOAP::Lite; sub c2f { my $self = shift; my $envelope = pop; my $temp = $envelope->dataof("//c2f/temperature"); return SOAP::Data->name( 'convertedTemp' => ( ( ( 9 / 5 ) * ( $temp->value ) ) + 32 ) ); } } use SOAP::Transport::HTTP; is marked as error if I comment it out use SOAP::Lite; is in turn marked as an error, not found etc the usual if a module is not installed. Both are installed with CPAN and $ perl -c soap-test.pl post-code-check.pl syntax OK Perl is fine CPAN tests are all pass, the code works, only EPIC lags behind. $ pwd && ls /opt/local/lib/perl5/site_perl/5.12.4/SOAP Client.pod Lite Server.pod Constants.pm Lite.pm Test.pm Data.pod Packager.pm Trace.pod Deserializer.pod SOM.pod Transport Fault.pod Schema.pod Transport.pod Header.pod Serializer.pod Utils.pod And if I have use errors in the start of my files the rest of the source is not error checked..

• Does fast typing influence fast programming?

  - by Lukasz Lew

  Many young programmers think that their bottleneck is typing speed. After some experience one realizes that it is not the case, you have to think much more than type. At some point my room-mate forced me to turn of the light (he sleeps during the night). I had to learn to touch type and I experienced an actual improvement in programming skill. The most surprising was that the improvement not due to sheer typing speed, but to a change in mindset. I'm less afraid now to try new things and refactor them later if they work well. It's like having a new tool in the bag. Have anyone of you had similar experience? Now I trained a touch typing a little with KTouch. I find auto-generate lessons the best. I can use this program to create new lessons out of text files but it's only verbatim training, not auto-generated based on a language model. Do you know any touch typing program that allows creation of custom, but randomized lessons?

• RemoteApp .rdp embed creds?

  - by Chris_K

  Windows 2008 R2 server running Remote Desktop Services (what we used to call Terminal Services back in the olden days). This server is the entry point into a hosted application -- you could call it Software as a Service I suppose. We have 3rd party clients connecting to use it. Using RemoteApp Manager to build RemoteApp .rdp shortcuts to distribute to client workstations. These workstations are not in the same domain as the RDS server. There is no trust relationship between domains (nor will there be). There is a tightly controlled site to site VPN between workstations and the RDS server, we're quite confident we have access to the server locked down. The remoteApp being run is an ERP application with its own authentication scheme. The issue? I'm trying to avoid the need to create AD logins for every end user when connecting to the RemoteApp server. In fact, since we're doing a remoteApp and they have to authenticate to that app, I'd rather just not prompt them at all for AD creds. I certainly don't want them caught up in managing AD passwords (and periodic expirations) for accounts they only use to get to their ERP login. However, I can't figure out how to embed AD creds in a RemoteApp .rdp file. I don't really want to turn off all authentication on the RDS server at that level. Any good options? My goal is to make this as seamless as possible for the end-users. Clarifying questions are welcome.

• IE 8 crashes when opening an html file from an autorun CD

  - by dave4351

  On Windows 7, when I insert a CD with a very simple HTML page referenced in the autorun.inf file, Internet Explorer 8 opens and then immediately crashes, with the error message "Internet Explorer has stopped working" and then checks for a solution. Then it says "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." On Windows Vista, IE 8 just opens and then closes silently, with no error messages or help of any kind. I have since discovered this is due to IE 8's "protected mode" and turning this off fixes the issue so that the HTML file on the CD launches normally. What I'd like to know: is there any way to get around this, so that I can launch a simple HTML file in the user's default browser, using an autorun.inf file on a CD, without first having my users open IE 8 and turn off protected mode? Perhaps the most bizarre thing is that if IE is already open when you insert the CD, the HTML page just opens--no crash. It only crashes if IE 8 happens to be closed when you insert the CD. And so a possible workaround may be to get the default browser to launch and then open the HTML file. All suggestions welcome.

• Stop Picasa (Mac) from scanning my harddrive

  - by Bodyscanner

  I want to use Picasa desktop app instead of the tedious & clunky web interface to share a couple of photos. Every time I launch Picasa it proceeds to open an annoying pop-up/tool-tip which flicks through every file on my HD using <=95% of CPU. I don't want this so I click the X. It appears again. I try to drag it somewhere less annoying onscreen but it pings back. I look in prefs for an option to turn it off. I give up and quit app until a new build comes out, which I download and repeat the above. WTF?! I understand Google can't be as cool as Apple - iPhoto isn't perfect by any means but at least it looks nice and 'just works'. I want to launch Picasa, not have it go through everything, not have 1000's of random pics and HD cruft on display in the list, and then perhaps drag in a few photos and upload them. Any idea of if that is possible? </rant>

• VPN being blocked somewhere between either my BT2700HGV and DLink DFL-210

  - by Dom

  Hi, For some time I have been unable to get VPN working through my set up. I have a BT2700HGV Router (2 Wire Model) and as a firewall I have the Dlink DFL-210. You can't turn the firewall completely off on the BT2700HGV so I have it set to DMZplus mode for the Firewall. In theory this should then allow the VPN ports through. On the Firewall I have a series of rules set up and one is the pptp-allow rule which should allow access on the correct ports also. When I try to connect via VPN however the client machine gets an error 809. If I check the log on the Dlink firewall, I see this record: http://dl.dropbox.com/u/1041315/packetdrop.PNG The laptop I am testing the vpn with is connected directly to the BT2700HGV router and I am trying to VPN from it onto 81.138.86.217. I can't work out whether I have some sort of problem in the set up of the rules on my firewall or if the BT router (even though it's in DMZplus mode) is still blocking port 1723. I read somewhere that there where problems because BTs Openzone held onto this port for some reason. Any help would be greatly appreciated. If you need further screen shots or information then please let me know. I wasn't able to create new tags for the router and firewall name or insert the picture in as I am new to the forum. Dom :-)

• Changing dual-monitor settings without closing the laptop lid on OS X

  - by hekevintran

  I have a Unibody MacBook hooked up to an external display. By default when I boot up, the system will go to dual-monitor mode. I want to use only the external display. The Apple supplied solution to this problem is to close the lid of the laptop which puts the machine into sleep mode and then move the mouse around to wake it up again. Because the machine is being woken up with the lid closed, when the displays are detected the system finds only the external. After the system is functional again, you can open the lid if you want and the laptop screen will be non-functional until you either tell the system to detect displays from the system preferences or you turn off the external display. Every time I want to use only the external display, I must reach my hand over to close the lid, wait for the machine to sleep, jigger the mouse, wait for the machine to wake up, and finally open the lid again because I don't want the machine to overheat. I feel that this is very stupid to have to do. Why is there no button or menu option that says "don't use this screen"? Is there any third-party software way to change the screen setup that does not involve physically closing the lid and playing a game of "are you sleeping" in order to switch such a simple software setting? We are in the 21st Century and honestly this is childish.

• Laptop will not boot

  - by WillumMaguire

  This is a dell studio 1558 laptop. Now, something is wrong with the charger that it won't charge the laptop, but the laptop can turn on and operate properly as long as it is attached. It has been like this for a while, but it's not the problem. My problem is that as of yesterday, It takes several minutes to get past the "dell" startup logo (where is says "f2 setup" and "f12 boot options"). After it gets past, it beeps as normal to tell me about the charger and gives me the f2/f12 options and f1 to continue as normal. I can press f12 to get into boot options and load into my live USB BackTrack 5 ISO, but after "startx" it just stays at a black screen. I can also access BIOS setup, but see nothing that would help the problem. When I boot to the HDD, it gives me this Intel UNDI, PXE-2.1 (build 083) Realktek PCIe GBE Family Controller Series V.2.29 (06/30/09) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM Operating System not found Also, pressing f8 gives me the same results as booting as normal. It is running Windows 7 Ultimate, dual-core Intel i3 @ 2.27ghz and 4gb RAM. I think there is an issue with the HDD, as the "Operating System not found" would lead me to believe. Is this a fixable problem?

• Apache times out after 2 minutes, when Apache TimeOut is 120

  - by Robert Gowland

  We have a set up where the browser makes an http request to Box A which in turn makes an http request to Box B. What we're encountering is that Box A waits for Box B to respond for two minutes then the users sees: The page cannot be displayed Explanation: There is a problem with the page you are trying to reach and it cannot be displayed. Try the following: * Refresh page: Search for the page again by clicking the Refresh button. The timeout may have occurred due to Internet congestion. * Check spelling: Check that you typed the Web page address correctly. The address may have been mistyped. * Access from a link: If there is a link to the page you are looking for, try accessing the page from that link. Technical Information (for support personnel) * Error Code: 404 Not Found. The requested item could not be located. (12028) Watching the logs on Box B we see that it takes 5 minutes to do the work requested. The problem is that the apache time outs on both boxes are set 1200 (20m), not 120 (2m). Any ideas where to look?

• JBoss7 load balancing with mod_proxy_balancer - session not working

  - by Phil P.

  I am trying to set up mod_proxy_balancer for routing requests to 2 jboss7-servers. For the time being I am testing this setup on my local machine, using following config in httpd.conf: ProxyRequests Off <Proxy \*> Order deny,allow Deny from all </Proxy> ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid scolonpathdelim=On <Proxy balancer://mycluster> BalancerMember http://localhost:8080 route=node1 BalancerMember http://localhost:8081 route=node2 Order allow,deny Allow from all </Proxy> and in the standalone.xml file of each jboss I have defined the jvmRoute system property: <system-properties> <property name="jvmRoute" value="node1"/> </system-properties> At http:// localhost/myapp the application is accessible but the java-session is not build up correctly. Consequently the authentication is not working. The funny thing is, that everything is working if I turn off one JBoss-instance. As I have tried a couple of settings already, I am thankful for any further suggestions.

• error creating MS Exchange distribution list: Active directory response: 00000005: SecErr: DSID-031521D0

  - by BabakBani

  We've migrated a client from google apps to an MS Exchange 2010 SP2 on-premise setup. The setup /prepareAD went well, and the software was installed with the Administrator account. We've used the Exchange Management Console to setup mailboxes and had to google up the appropriate workarounds such as going into each users Advanced Security Settings and selecting "include inheritable permissions from this object's parents", and changing their logon-to from specific machines to "all computers" so that they can connect to Outlook Web Access, and in turn so their Outlook 2007-2010 clients can connect to Exchange. Sending and receiving emails are working well. Now that all this is in place, we can create Dynamic Distrubution Lists with no problem, but as soon as we try and create a DISTRIBUTION LIST, either in the EMC or the Exchange PowerShell, we get an error. As the error message in the powershell is more verbose, I include this if anyone can suggest how we remedy this: [PS] C:\Windows\system32new-DistributionGroup -Name 'projects' -SamAccountName 'projects' -Alias 'projects' Active Directory operation failed on DC.cppe.local. This error is not retriable. Additional information: Access is denied.

• Find out the type of an automounted device

  - by Steve Bennett

  I'm working on a system (Ubuntu Precise) with a mount defined in /etc/fstab as follows: /dev/vdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 Originally I just wanted to find out if it's NFS (due to potential MySQL locking issues). Judging from man mount, it's not: If no -t option is given, or if the auto type is specified, mount will try to guess the desired type. Mount uses the blkid library for guessing the filesystem type; if that does not turn up anything that looks familiar, mount will try to read the file /etc/filesystems, or, if that does not exist, /proc/filesystems. All of the filesystem types listed there will be tried, except for those that are labeled "nodev" (e.g., devpts, proc and nfs). If /etc/filesystems ends in a line with a single * only, mount will read /proc/filesystems afterwards. But, out of curiosity now, how can I find out more about what type of device it actually is? (For context, this is a VM running on OpenStack. The device is a 60Gb allocation mounted from somewhere - but I don't know how.)` EDIT Including answers here: $ mount /dev/vdb on /mnt type ext3 (rw,_netdev) $ df -T /dev/vdb ext3 61927420 2936068 55845624 5% /mnt

  I ran mysql query as below on a non-partition table mysql> use test31 Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> explain partitions SELECT * FROM my_friends WHERE (requestor = '1234567890' OR contact = '1234567890') AND status = 1 ORDER BY request_id DESC LIMIT 0,100\G *************************** 1. row *************************** id: 1 select_type: SIMPLE table: my_friends partitions: NULL type: index_merge possible_keys: friend_index,requestor,contact key: friend_index,contact key_len: 17,17 ref: NULL rows: 2 Extra: Using sort_union(friend_index,contact); Using where; Using filesort 1 row in set (0.00 sec) on a partition table mysql> explain partitions SELECT * FROM my_friends WHERE (requestor = '1234567890' OR contact = '1234567890') AND status = 1 ORDER BY request_id DESC LIMIT 0,100\G *************************** 1. row *************************** id: 1 select_type: SIMPLE table: my_friends partitions: p1_p1sp0,p1_p1sp1,p1_p1sp2,p1_p1sp3,p1_p1sp4,p1_p1sp5,p1_p1sp6,p1_p1sp7,p1_p1sp8,p1_p1sp9,p1_p1sp10,p1_p1sp11,p1_p1sp12,p1_p1sp13,p1_p1sp14,p1_p1sp15,p1_p1sp16,p1_p1sp17,p1_p1sp18,p1_p1sp19,p1_p1sp20,p1_p1sp21,p1_p1sp22,p1_p1sp23,p1_p1sp24,p1_p1sp25,p1_p1sp26,p1_p1sp27,p1_p1sp28,p1_p1sp29 type: index_merge possible_keys: friend_index,requestor,contact key: friend_index,contact key_len: 17,17 ref: NULL rows: 60 Extra: Using sort_union(friend_index,contact); Using where; Using filesort 1 row in set (0.01 sec) What does the "rows" mean? less rows is more faster query?

• COMPAQ Tower No Signal to monitor

  - by Lancelot

  Hi there, I have had some troubles with this: I received a compaq tower: Compaq Presario SR1224NX Onboard VGA Windows XP SP2 from a friend. It was given to me on condition i give her the files back. My plan was to turn this into an Ubuntu Server. It booted up no problems even with the ubuntu live disc. After a normal shutdown(not unpluggin the power cord and not doing a hard shutdown with the power button), it would not restart even after SEVERAL attempts. I realized the light next to the power supply would flash very rapidly. I researched and found out it was one of two things: a dead power supply or the cables to the motherboard and to the disks etc. Thus i checked to ensure the cables were fine(and they were). I purchased a Power Supply (this one has 400 watts, the initial had 250) and installed it. The tower now boots. It booted into the live disk and everything. After a normal shutdown, it now restarts but is not sending signal to my monitor. I have tried several monitors in which i assure work perfectly but not with this tower(i recall it did show display after replacing the power supply). The monitors are ACER. This is different than most "no Signal" problems since i am not using an external Video Card, this is onboard VGA. Thanks!

• Internal and External DNS from Different Servers, Same Zone

  - by Shane

  Hello All, I am either having trouble understanding how DNS works, or I am having trouble configuring my DNS correctly (either one isn't good). I am currently working with a domain, I'll call it webdomain.com, and I need to allow all of our internal users to get out to dotster to get our public DNS entries just like the rest of the world. Then, on top of that, I want to be able to supply just a few override DNS entries for testing servers and equipment that is not available publically. As an example: public.webdomain.com - should get this from dotster outside.webdomain.com - should get this from dotster as well testing.webdomain.com - should get this from my internal dns controller The problem that I seem to be running into at every turn is that if I have an internal DNS controller that contains a zone for webdomain.com then I can get my specified internal entries but never get anything from the public DNS server. This holds true regardless of the type of DNS server I use also--I have tried both a Linux Bind9 and a Windows 2008 Domain Controller. I guess my big question is: am I being unreasonable to think that a system should be able to check my specified internal DNS and in the case where a requested entry doesn't exist it should fail over to the specified public dns server -OR- is this just not the way DNS works and I am lost in the sauce? It seems like it should be as simple as telling my internal DNS server to forward any requests that it can't fulfill to dotster, but that doesn't seem to work. Could this be a firewall issue? Thanks in advance
