  • How should I force-enable BIND's persistent cache, or Unbound's persistent cache

    - by Jacob Rabinsun
    I am trying to run a local DNS server on my home computer so that I can both increase DNS lookups speed and reduce bandwidth use, so that both my laptop and my PC can do lookups faster. I have got BIND 9 running very smoothly, there is only one simple problem, and that being the fact that BIND is not a persistent DNS cache, and if I restart its service, the whole cash would be wiped out. So, is there a way that I could make BIND9 keep its cache after system restart? Also, which one is better Unbound or BIND? Which one would you suggest? Does Unbound DNS have a persistent cache or can it be enabled?

  • Force copy files off CRC error filled hard drive

    - by TheLakersHighlights
    So I got a dying Western Digital hard drive here and I have a new Western Digital hard drive to transfer all the data to. I have the new HDD hooked up by a SATA to USB. I want to transfer all the pictures, etc to the new HDD. I am unable to because of the CRC error. I have ran chkdsk /f /r and it didnt work because the drive is just simply dying. What tool will let me bypass CRC and continue on with the copying? OS: Vista Home Prem. 32bit

  • Force Capistrano to ask for password

    - by Moshe Katz
    I am deploying using Capistrano to a new server and having the following issue. Currently, I cannot add an SSH key to the server to log in with so I must use password authentication. However, I do have a key for another server saved in my local user account's .ssh directory. Here is the error I get when I try to log in: C:\Web\CampMaRabu>cap deploy:setup * executing `deploy:setup' * executing "mkdir -p /home2/webapp1 /home2/webapp1/releases /home2/webapp1/shared /home2/webapp1/shared/system /home2/webapp1/shared/log /home2/webapp1/shared/pids" servers: ["myserver.example.com"] connection failed for: myserver.example.com (OpenSSL::PKey::PKeyError: not a public key "C:/Users/MyAccount/.ssh/id_rsa.pub") How can I get Capistrano to ignore the existence of the key I have and let me log in with a password instead? I tried adding set :password, "myp@ssw0rd" to deploy.rb and it didn't help.

  • Force socket close

    - by Groo
    Is it possible to close an established socket connection in Windows "manually" (e.g. using a command prompt tool)? I have several open sockets connected to a listening server, I can see them using netstat, and would like to close one of them manually.

  • EC2 Ubuntu - Force instance to use internal IP

    - by Peter
    I've just set up a micro instance on EC2 (AMI ID ami-e59ca991). I had hoped to avoid charges for a year as my usage falls well within the bound of the free tier. I have been charged $0.01 for "regional data transfer". I read here that this is because my instance is talking to its self via it's external IP address. From what I've Googled it looks like you can stop the charges by making sure that the instance uses its internal IP address. However, when I ping the hostname of my instance internally (via an ssh session) it resolves to the instances internal IP address. How can I configure my instance so that I do not get these charges? Is it as simple as adding a line to my hosts file? Additionally, is this the real reason for the charge? I'm concerned that I've misunderstood the pricing somewhere. I have Apace and MySQL (with phpmyadmin) running on the machine - could I be being charged for data transfer associated with these (I have only one flat HTML page and I have only logged in via phpmyadmin - I have no data in my database). Edit: Additionally, my user account on MySQL was declared as: grant all privileges on *.* to 'peter'@'localhost'; Should I have instead used the internal hostname for the instance? grant all privileges on *.* to '[email protected]'; Cheers, Pete

  • Debian (wheezy) force cache to RAM

    - by Marek Javurek
    I have Linux server running about 6 game servers. I have 3 GB total of RAM but I use only about 500 MB. Is there a way to cache one of my game servers (all the files - even not actually used maps etc. - about 1,5 GB) to RAM? The reason I want to do this is because my Linux server is virtual and the hard drives ar very slow, so there is really big IO wait time. IO: http://i.stack.imgur.com/7HLhB.png

  • Force netsh/arp binding multicast IP addres with specific MAC address

    - by Olivier
    I would like to setup an binding from an IP address to a MAC address using netsh. Goal is to bond an IP address which is a multicast address (224.224.x.y) to a given MAC address (which is NOT the calculated one from the multicast IP address : 01:00:5e:X:Y:Z It used to work with Windows XP (was it a bug that used to be "perfect" for my needs?), but Windows 7/8/8.1 forces the MAC address to the calculated one instead of letting me put what I want! (http://nettools.aqwnet.com/ipmaccalc/ipmaccalc.php shows MAC address calculation for multicast IP address) Thus I'm doing the following. Listing existing mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static Then adding my interface mapping manually: netsh.exe interface ip add neighbors "Ethernet" "224.xxx.yyy.zzz" "00-80-EE-UU-VV-WW" Finally, listing again my mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static **224.xxx.yyy.zzz 01-00-5e-UU-VV-WW static** As you can see, the MAC Address of the second entry (the one I just made) has been dynamically replaced by the calculated MAC Address corresponding to my IP Address... Calculation is done as follow (and displayed in hexa): UU=(xxx-128) VV=yyy WW=zzz But I don't want that behavior. My IP address and MAC address cannot be changed, and I must associate them accurately. Does anybody know how to disable MAC address substitution/calculation in netsh? Thanks, Olivier.

  • apache2 force proxy for specific url on a subdomain

    - by Tony G.
    Hi, I have a site that has dynamic virtual subdomains using mod_rewrite, as defined like this: <VirtualHost *:80> ServerName example.com ServerAlias *.example.com DocumentRoot /var/www/example.com/www RewriteEngine on RewriteCond %{HTTP_HOST} ^[^.]+\.examle.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^([^.]+)\.example.com(.*) /var/www/example.com/$1$2 </VirtualHost> The problem is that I want a specific url, say subdomain.example.com/CONTROL/ to point back to www.example.com/ using a proxy (not url redirecting). I have tried adding: RewriteRule ^([^.]+)\.example.com/CONTROL(.*) /var/www/example.com/www$2 [P] But that didn't work. Any ideas?

  • Force database read to master if slave data is stale

    - by Jeff Storey
    I previously asked a specific question about this database replication for new user signup to which I got an answer, but I want to ask this in the more general sense. I have a database setup in which I am using a master/slave combination. I am using the slaves for load balancing (the data itself is partitioned/sharded across multiple databases, but each database has X slaves for load balancing). Let's say I write some data to the master. Now I do a subsequent read which hits a slave, but the slave has not yet caught up to the master. Is there a way (which can be done quickly since it will happen frequently) to determine if the data is stale in the slave so I can then route to the master? In my previous question, it was suggested to do simultaneous writes to the cache and the database. This solution seems practical, but there is still a chance that the data may have been removed from the cache but not yet updated in the slave. A possible solution is to ensure the cache is big enough (based on the typical application load) so the data will not be evicted within the time frame it takes to replicate the data. This seems like it may be feasible. Can anyone provide additional insight into this question? Thanks!

  • Win Server 2008 force kerberos setting

    - by ftiaronsem
    I am currently facing the problem that a linux machine running Ubuntu 10.04 LTS with samba and winbindd installed is unable to join a Domain, that is managed by a Windows 2008 DC. The linux config, is probably alright, since I have successfully used it at multiple sites, running 2008 as well as 2003 DCs. The error I get ("libads/kerberos.c: Join to domain is not valid. Client credentials have been revoked"), indicates that there is a kerberos problem. Normally the linux box is supposed to authenticate via NTLM and is configured that way. The only reason I can image why it tries kerberos is that the DC is forcing it. Do you know whether there is any setting in the security policies of a window 2008 server, that would completely block NTLM, forcing kerberos? If so, where can I find this setting?

  • Force SSL on one page via .htaccess without looping

    - by Will Martin
    Okay, I have this code: RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/borrowing/ill/request\.php$ RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [R,L] The way I would expect this to work is: A request for /borrowing/ill/request.php comes in on HTTP. The rule matches. The server redirects to HTTPS. The rule does not match, because HTTPS is now on. The way it actually works is: A request for /borrowing/ill/request.php comes in on HTTP. The rule matches. The server redirects to HTTPS. The rule matches. The server redirects to HTTPS. The rule matches. The server redirects to HTTPS ... And so on. I know that the second condition (matching the file name) is working, because the redirect loop only hits that specific page. The question is, why isn't the switch to HTTPS causing the first condition to not match? EDIT: I put the exact same .htaccess rules into a test area on another server -- same file and path info. And they worked just fine. There's got to be something wrong with the server configuration elsewhere.

    Let's say I have a video running in an application. If I hover my mouse over the taskbar, it shows a little popup windows that diplays the video (aero peek). Sometimes I'm running a maximized window and I want to have this little screen always popped up. (Kind've like when your using the TV Guide menu, you still see a little clip of the video)

  • Microsoft IME + Japanese: Force Hiragana input by default?

    - by Mica
    I am using Windows XP SP3 and Windows 7. On both machines, I cannot make Hiragana the default input method. Is there a way to do this? In the IME tool bar, there is the option to set the "Input Mode." This is always defaulted to "Direct Input." I would like to default to Hirgana or Katakana. I have found the setting dialog for this, by right clicking on the IME toolbar - settings - Japanese IME Standard - Properties - Default Input Mode. This setting seems to have no effect, no matter the combination of selections in the dialogs. Is there a way to reliably set the default Input Mode?

  • Cisco ASA 5505: Force NAT before IPsec?

    - by WuckaChucka
    I'm trying to route public-to-public IPs over an IPSec tunnel. However, the src IP is not "interesting" to the Cisco's IPSec engine because it doesn't appear to be getting translated to the outside IP before being evaluated by the Cisco's IPSec engine. From WEST to EAST, my public-to-public IPSec works fine: I can make a request from 192.168.0.5:any to 200.200.200.200:80 because the Vyatta does the NAT translation before the IPSec tunnel inspects the traffic, so the remote-subnet and local-subnet matches (see below). However from EAST to WEST, I see a deny in my Cisco logging buffer for Deny tcp src inside:192.168.1.5/59195 dst outside:100.100.100.100/80 which leads me to believe that the IPSec engine is not matching the encrypt_acl because the address has not been translated yet. Any ideas? WEST (Vyatta): inside: 192.168.0.0/24 inside host: 192.168.0.5/24 outside: 100.100.100.100 IPSec local-subnet: 100.100.100.100/32 IPSec remote-subnet: 200.200.200.200/32 EAST (Cisco): inside: 192.168.1.0/24 inside host: 192.168.1.5/24 (DNAT'ed on port 80 to outside) outside: 200.200.200.200 IPSec local-subnet: 200.200.200.200/32 IPSec remote-subnet: 100.100.100.100/32

  • Meinberg ntp for Windows - force more frequent updates?

    - by ana
    I have a Windows VM that has time drift problems, and left to its own devices will drift by minutes per day. I know there are issues with time on VMs, but I was hoping using the Meinberg NTP service would be successful. It works, generally, in that the time gets corrected in one big step about once every 70mins when it's at about 10mins offset. This has totally confused me as I thought NTP was meant to drift gently back towards the right time, and panic and die if the offset was more than 3 minutes. So (a) what is happening and (b) how do I make it update more regularly?

  • Force spin-down of external hard-drive on linux (raspberry pi)

    - by user258346
    I'm currently setting up a home-server using a Raspberry Pi with an external hard-disk connected via usb. However, my hard-drive will never spin down when being idle. I tried already the hints provided at raspberrypi.org ... without any success. 1.) sudo hdparm -S5 /dev/sda returns /dev/sda: setting standby to 5 (25 seconds) SG_IO: bad/missing sense data, sb[]: 70 00 04 00 00 00 00 0a 00 00 00 00 44 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2.) sudo hdparm -y /dev/sda returns /dev/sda: issuing standby command SG_IO: bad/missing sense data, sb[]: 70 00 04 00 00 00 00 0a 00 00 00 00 44 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...and 3.) sudo sdparm --flexible --command=stop /dev/sda returns /dev/sda: HDD 1234 ... without spin-down of the drive. I use the following hardware: Inateck FDU3C-2 dual Ports USB 3.0 HDD docking station Western Digital WD10EZRX Green 1TB Is it possible, that the sent spin-down-signals are somewhere overwritten/lost/ignored?

  • Force Colloquy not to use built-in Growl notifications

    - by thepurplepixel
    Whenever Colloquy needs to pop up a notification (for example, when you are PM'd), it uses its built-in Growl notifications, which really annoy me because they stay on the screen until they are clicked (at least NOTICE's do anyways). I'd like to make Colloquy use the Growl that I have installed on my Mac, not its built-in Growl notifications. That way, I could change its preferences from the Growl .prefpane and it would match the look of all my other notifications. I seem to remember this being possible (maybe in a bug report or something), but I can't remember how. Thanks!

  • How force text-only pasting in emacs?

    - by eaubin
    On my mac I always have an emacs buffer open and occasionally I have to copy content from PowerPoint or Word. Unfortunately, copying to the clipboard and yanking into emacs saves all the ugly formatting (and graphics) from the original document. I only want to paste in the text (and never the formatting). My current solution is to paste into TextWrangler and then repaste into emacs. What's a better way to do this?

  • Force Finder to log in as Guest to a SMB share

    - by slhck
    I have a QNAP NAS that offers a few SMB shares. As I'm in a trusted environment, my shares are accessible as guest rather than with a combination of username and password. Problem Now, when I click the name of the device in Finder's sidebar, I get the black "Connection failed" bar, with the option "Connect as...". When I click that, I receive: I can however press ? + K and enter the server's name manually, which gets me to this window: Here, I have to select "guest". Now, I can select one of the shares to connect to, and I'm finally connected to the server. If I select it in the sidebar, I get a list of all shares available, because I'm connected as "guest", obviously: What I need Well, as soon as I unmount all shares, I have to go through the same procedure of manually logging in as "guest" again, which I find quite annoying. Is there any way I could get Finder (or the underlying SMB client) to know which credentials to use? Or should I look for the solution rather on the server side? (I know that other SMB shares seem to work fine in my network) Diagnostics The only thing I can get out of Console.app is: 5/15/11 7:36:40 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[200] SharePointBrowser::handleOpenCallBack returned 64 This message occurs when I click the name of the SMB server in the Finder sidebar.

  • Force local IP traffic to an external interface

    - by calandoa
    I have a machine with several interfaces that I can configure as I want, for instance: eth1: 192.168.1.1 eth2: 192.168.2.2 I would like to be able to forward all the traffic to one of these local address trhough the other interface. For instance, all requests to an iperf, ftp, http server at 192.168.1.1 are not just routed internally, but forwarded through eth2 (and the external network will take care of re-routing the packet to eth1). I tried and looked at several commands, like iptables, ip route, etc... but nothing worked. The closest behavior I could get was done with: ip route change to 192.168.1.1/24 dev eth2 which send all 192.168.1.x on eth2, except for 192.168.1.1 which is still routed internally. The goal of this setup is to do interface driver testing without using two PCs. I am using Linux, but if you know how to do that with Windows, I'll buy it!
