SEO TIP Reduce DNS Lookups Rocket Speed Web Page

2010-11-16T13:18:00.000-08:00

How to make a rocket speed web page Domain Name System. The DNS charts the hostnames to IP locations, in the same way as the book yellow pages dose map out houses and businesses to their company phone numbers.

After you have opened up your Firefox browser and the entered some thing like www.google.com the Domain Name System resolver sends back the web server IP address, but this dose have a price of time.

The DNS characteristically clocks up around 20-120 milliseconds to complete the DNS lookup request from the hostname chosen IP address location. The pour burning fox has to just site there and can't download the date packagers a web hostname server pending the DNS lookup has been fully accomplished its task, e.g. time to first bit.

The Domain Name System lookups are cached to provide improved webpage performance. The dater record storage system runs on dedicated caching web servers, controlled from your ISP internet-service-provider otherwise a LAN local-area-network, nevertheless in accompaniment to this the file caching also take place for each individuals home computer unit.

The DNS record information stays in your operating system DNS Client cache, the dnsrslvr.dllon Microsoft Windows operating systems. The majority of modern day web browsers include a webpage cache this is independent from your windows operating system file cache. Whilst internet explorer maintains a DNS-record within its own cache, IE has no necessitate asking the operating system for the request record.

The standard cache lookup setting for Internet Explorer is 30 minutes, set with the DnsCacheTimeout registry configuration. The Firefox default cache DNS lookups that are set for 1 minute will be changed by Fasterfox to 1 hour, controlled by the network.dnsCacheExpiration data setup configuration.

At the point were the cache on the client side DNS is empty, both Internet Explorer and the windows system, its quantity figure of DNS lookup resolutions are equal to the number of unique web severs hostnames in your Blog web page. This includes all http requests used in the page's URL, Java, images or script files, and stylesheets, Adobe shockwave Flash objects, any that is required from another source.

The best practice for rocket speed web page performance is to reduce the requests, but having only 1 would be as bad as having 20 of them.

Dropping down your sites page quantity of unique hostnames will equally decrease the amount of name lookups to be implemented by the DNS server.

Sinking the amount of unique web host sever names would-be a decrease in the total number of parallel requests downloading that is happens on your website.

Try to steer clear of large amounts of DNS lookups, they really do cut the response download time, but reducing parallel downloads may increase download response period.
It's really best to do a server waterfall test, to see how your site is loaded, you can only get to things from one place a once.

I think it is good to divide the file components across four to nine hostnames but try not to have much more. Some people say 2 to 4 hostnames but there site will not be very interactive e.g. not nice Face book social network widgets or Youtube videos and so-on.

What is required is a nice loading balanced compromise sandwiched between the reducing of your DNS lookups along with permitting a lofty quantity of parallel sever downloads.

Q. How will Google reward me for this, rocket speed web page reduce DNS Lookups a fast site?
A. I got one of my kids sites speed down from 13 sec to about 4.5 sec and got about 35% increases in traffic.

Website bandwidth server speed test

2010-02-21T12:51:00.000-08:00

Have you ever wondered what broadband internet speed you are really getting from your dsl internet connection provider? There are many sites offering free Website bandwidth server speed test to find out the true internet speed, they will provide you with an upload and download transfer rate.
I have just done a wireless bandwidth test of my dsl line here and it was very poor this is what I got don’t laugh at my dsl speed test results remember I live in the jungle now.

 Last Result:
Download Speed: 497 kbps (62.1 KB/sec transfer rate)
Upload Speed: 48 kbps (6 KB/sec transfer rate)
22 February 2010 04:05:01

It’s a fare cry from when I was back in England on a fixed IP address with Website bandwidth server speed test that I would do there. You should do a charter internet speed test just to see what you score the site I did my server speed test on was http://www.bandwidthplace.com/ there Website bandwidth meter looks a bit like a old car speedometer.

DNS Authoritative

2010-02-05T21:22:00.000-08:00

DNS Authoritative

The DNS authoritative name server are domain name servers which return a queries that have only the original record source code from its master administrator configuration setup allows. DNS authoritative normally works with two main concepts the web server is going to deliver back the return of authoritative internet domain name server responses or the D.N.S can be set so it won’t cache any records.
The Requirements that you will knead in setting up your own authoritative DNS server are one or greater number of static IP addresses from your intern provider. The name registries require you to have two or above number of fixes IP addresses this is the rule of thumb in most cases. The zones can be set to master or slave for one or more of the domains has to be set for running an authoritative DNS.
This is used in some ways like a fire wall for example, if your internet domain administrator configuration setups or by dynamic DNS methods, can bring back a different query answers compared to a regular DNS query on another domain name server. The DNS authoritative only name server will just return only the query answer for the domain names system that have been dedicated or aloud in the specifically configured by the administrator.

The dns authoritative name-server can be a master domain or a slave server system. A master server stores the original file copies of all zone records the country registrar is going to require your server to have the entire different zone to be authoritative dns for set up beforehand you submit for registration.
An example of a bind zone file
$TTL 86400
@ IN SOA ns1.dns4you.com. dnsadmin. somesite.com. (

2010022427 ; Serial number
864000 ; Refresh after 10 days (secs)
36000 ; Retry after 100 mins
3600000 ; Expire after 42 days
864000 ) ; Minimum TTL 10 days

IN NS ns1. somesite.com.
IN NS ns2. somesite.com.

IN MX 0 mail

IN A xx.xx.xx.xxx

ns1 IN A xx.xx.xx.xxx
ns2 IN A xx.xx.xx.xxx

mail IN A xx.xx.xx.xxx

www IN A xx.xx.xx.xxx
ftp IN CNAME www.somesite.com.

The slave dns server communications with the DNS protocols to update the master system to automatic maintain an identical backup file copy of the master records.

All of the Domain name server NS zones should have a bind configuration definition and are to be assigned their own group of authoritative name servers that are placed into the parent zone NS records.

When you buy internet domain and then have it registered at the domain registrar service their installation setup in the domain registry has a top level domain that requires the assigning to the primary name server along with the accompaniments of least one or more secondary naming system. The main reason for the several servers is to make the domain constantly in action even if ether the name slave or master server kicks the dust and becomes inaccessible or corrupted in some way. The final designation point of the primary is singularly determined with its DNS authoritative priority settings imputed at the internet domain registrar service. For this application use mostly fully qualified domain names of the name server are applicable or a DNS accommodate at the registered domain in circumstance a corresponding IP address is necessary also.

MISP or multihomed FreeBSD host

2010-01-16T08:01:00.000-08:00

If you live in a country side remote location and you need faster internet connation than relevant locale internet providers can supply you with there is two options you could use for joining two hookup connections together (Multihomed) to go twice as fast on the download and uploading files. There are two main ways of accomplishing this task to get twice the internet speed by adding (2 rabbits) remote area broadband they are MISP a Multihomed Residential Gateway and multihomed FreeBSD host system.
The multihomed FreeBSD is more for the corporate lager business systems configure as network gateway. The FreeBSD host network interface installed has to be setup so you can ping both ISP at the same time.
The MISP a Multihomed Residential Gateway is a hardware box that you configure similar to how you would set au a standard router system.

rndc bind

2009-10-16T11:44:00.000-07:00

Rndc bind Remote Nameserver Daemon Controller. This Rndc title description shows it's possible to have the ability to convey the operation in manipulating the command of a chosen name-server from in another location, the rndc bind controls include the command procedures of starting, stopping and restarting the whole name-server in every part or its. If you wish to enforce a reloading on a singe zone, without cutting it off or interrupt its performances, having to restart every part in the whole daemon

The bindrndc Error: connect failed: 127.0.0.1#953 is stating the utility of the "rndc" supplied as component in the BIND9 is falling short in attaching a connection linkup to the essential socket on the local hosts network. On performing a script run with the /etc/inid.d/bind9, you may see that not every one of its procedures will all ways course the invoking of the bind RNDC.
The /etc/named.conf and /etc/rndc.conf must be the same as each other.
Rndc is very helpful in seeing the Name Server's Cache data to find possible Problem for
BIND 9 apply the rndc dumpdb and for
BIND 8 apply the ndc dumpdb
Here is some Key to put on your key ring or enter in to your ZX spectrum its up to you.

Remove Existing Key File = remove the rndc file

Standard install = rm -f /etc/bind/rndc.key

chroot install = rm -f /var/lib/named/etc/bind/rndc.key

chroot install = vi /var/lib/named/etc/bind/named.conf

Remove rndc key specification /etc/bind/named.conf file on a normal install = vi /etc/bind/named.conf

make a new key file rndc-confgen = rndc-confgen -r /dev/urandom –a

adding a reference to the new key with named.conf file = vi /etc/bind/named.conf

producind a fresh rndc.conf file = vi /etc/bind/rndc.conf -k dnsadmin -b 256

-k option is of setting the essential name of the key produced by rndc-confgen reset it to a dissimilar value from its standard default naming of the bind rndc-key. I highly recommended a modification to the key name.
-b is option sets the key size 1 to 512 bits. Default 128 bits for a public DNS server 256 or more is best practice

options {
default-server localhost;
default-key "rndc-key";
};
server localhost {
key rndc_key;
};

key rndc_key {
algorithm hmac-md5;
secret "xxxxxxx==";
};
include "/etc/bind/rndc.key";

how to stop Bind = /etc/init.d/bind9 stop

how to start Bind = /etc/init.d/bind9 start

to closed all named connections = netstat –tap

BIND 9.2.0 and newer name server can flush the cache but oldies have
to kill all named connections = killall named

to flush cache BIND 9.2.0 = # rndc flush internal
to flush cache BIND 9.3.0 on attached records at any particular domain= # rndc flushname somesite_eg_whatever_.com

Upgrade BIND howto update bind 4 to 8-9

2009-10-07T04:06:00.000-07:00

To Upgrade BIND first the named.boot file will need Converting as a parallel equivalent with the extension of �.conf�, to named.conf file by applying the named-bootconf.sh but you can do this task by hand if one wish to.
By manually changing the directory of /etc/named.conf file instead of using the Bind Configuration Tool will course this problem. The alterations you have made to the files are going to be overwritten on the next occasion Bind Configuration Tool is run. So for a starters it�s best to go with the Bind Config tool.
Here is BIND 9's the root directory for contrib/named-bootconf.sh and for directory in BIND 8 it�s the bin/named-bootconf.sh . The named-bootconf file looks at the input format in the named.boot then it can make a new output named.conf file
e.g
$ named-bootconf.sh < /etc/ named.boot > named.conf

How to clear dns cache flush dns cache

2009-10-05T05:22:00.001-07:00

To clear dns cache or flush dns cache can be done by the rebooting the machine, but this is not the most practical way of doing this. The resolver cache has a preset default period of storage time of 24 hours, which holds the IP address in the dns cache. This time period of 24 hour can produce an error if the address in the (ULR) Uniform Resource Locator has altered before the period is over. This particular dns error or 404 pages in your browser is not the most of common occurrences but some times will happen. This can also some times happen when there are high Internet traffic large loads on the main server making it will through out a negative response because the Uniform Resource Locator is temporarily busy. Resulting in the old records - negative responses still located in the local cache. The preset default period is about five to six minutes or more before negative response clearing dns cache is fixed and restored to the correct value.
To clear dns cache and flush dns cache.

Go to the Start Run and Click it.

Then you Enter the command line ipconfig /flushdns in the Open dialog textbox.
Next click on the OK button then the flushing cache is all done.

To stop the placing of negative entries into cache dns, alter the registry key in. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Dnscache\Parameters
make a fresh DWORD with a name of NegativeCacheTime and set it value to zero.

DNS Disable.

How you can turnoff the DNS lookups for the local computer. This will reduce a small amount of much-needed bandwidth and makes DNS lookups a little quicker by not resending the same dns client data. There is also the great saving of CPU time and services.exe 3,000 k memory cut down it all helps.
· Go to the Windows Control Panel double click “Administrative Tools.” icon it’s the one with the blue hammer.
· Double click on "Services" icon it’s the one with the two cog wheels
· The service panel will open then double click on the "DNS Client" service to get to the Resolves and caches Domain Name System (DNS) names.
· The DNS Client properties (local computer) panel will open then find the Start-up type pull down set it to "Disabled".
· Click on the "Stop" button once.
· Last click "OK"

DNS Disable dynamic update.

Find the Internet protocol TCP/IP properties click on advanced on the DNS tad “uncheck register this connection adders” Last thing click "OK"
Or you can go into the registry find the key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interface and change the value of 1

Disable TCP clients.
This is mostly used for the limitation of concurrent TCP clients but you can set this to zero “0” so there is none. Apply a bind-9 tcp-client sub statement.
Options {
directory “/var/yourname”;
tcp-clients 0;
};
This will now disable the TCP queries and zone transfers for forwarding. But most queries are by default User Datagram Protocol (UDP) based.
If you just wanted to limit the traffic TCP clients to 200 you would neter4 this bind-9 tcp-client sub statement.
Options {
directory “/var/yourname”;
tcp-clients 200;
};

I recommend that only the true DNS servers should have the cache DNS information enabled. But Microsoft enabled this by default but this was done before DNS poisoning, pharming was a big problem with the evil attackers.

If you with to delete all the DNS resolver cache to speed up Web browsing go to the command prompt and then type “ipconfig /flushdns”. This will flush out the old addresses that have been looked up recently.

How to Enabling or Disabling DNS Lookup.

To disabled DNS lookups resolution, - Router (config) #no ip domain-lookup
To enable resolution DNS lookups - Router (config) #ip domain-lookup
Warnings with doing theses changers to the global configuration mode you will loss the DNS requests/responses in the IP packets, prevents a router from doing the name lookups.

Unable to bind to the destination server in dns.

2009-09-21T21:19:00.000-07:00

What
operating systems you are using where external users are being hosted are very important to find the correct solution to this problem. In most cases the Exchange System Manager Queues,error message "unable to bind to the destination server in DNS" is it needing to forward the SMTP connector message and can’t locate the (MX) record in the Exchange server or they are corrupted in some way stopping entrance tothe domain in DNS E.g. if your trying send something like this Mr_man_one@someplace.com to Mr_man_two@otherplace.net across two exchange server with different domain names.

Another possible cause of thiserror message is the (IIS)Internet Information Services after the reinstalled of IIS SMTP service or just IIS. It will update the Simple Mail Transfer Protocol(SMTP) but not its SMTP Exchange extensions. It may just be the issue with incorrect settings on the DNS or TCP/IP if they look ok use the Exchange server NSLOOKUP to verify MX records are ok.

Warcraft 3 no cd.

2009-09-09T04:41:00.000-07:00

If you have a problem with your Warcraft not starting or it’s coming up with Warcraft 3 no cd or Warcraft 3 unable to initialize DirectX, there is a couple of possible reasons why it’s doing this. The first place to start is to look at, is your grafix card setting, the acceleration-setting might be set to high. It’s in the display properties – advanced – troubleshooting tab then turn the hardware acceleration down to the 3-4 notches. this will allow you to run in a lower graphics mode. In high graphics card modes some of the functions in the DirectX runtime are disabled or not available. On the display properties the pull down tab for the Colors set that to its lowest setting.
The correct grafix card driver is very important as well if you have installed the wrong driver version the card will work for most stuff but will not be able to access all of its working possible modes.
You can open the directx dialog box “Dxdiag.exe” to see what is working in the Diagnostic Tool. DirectX diagnostics first came out in DirectX 6.0.
To find the Dxdiag.exe file so you can test Click on the Start then select the menu item Run, In the Run dialog box, type: dxdiag then Click Ok.
If there is some cd burning software on your computer and a virtual drive program this can cause a problem as well because it interferes with the ante pirating of the Warcraft 3 cd. Try deleting the virtual drive.
Hopefully these steps will fix your game and no more seeing the
“Warcraft III was unable to initialize DirectX. Please ensure you have DirectX 8.1”, then you will be ready to work.
Here are the Warcraft 3 cheats.

Dns windows 2003

2009-08-24T16:07:00.000-07:00

The dns windows 2003 installation of DNS is pretty strait forward the first thing to do is making sure that all the windows 2003 service packs (SP) are installed and the Windows Update has the current data files. In the past date stored in a local server host files need to be updated by systems administrator on each machines name resolution. Now think about having to maintaining every hosts data files on every Internet domain name and all the sub domains that are working on the Internet, as we know it. So the Internet authorities introduced DNS a distributed database service for the resolution of IP addresses to names that can understand. Going of track a little bit here 192.123.123..244 = wwww.whatever.com, numbers to words, if you see #cococo or # ff4466 do you see the color…..? Now back to the dns windows 2003 installation so you can get the vital service and active directory running with more versatility than the old WINS (Windows Internet Naming Service). Its really best practice to have 2 dns server so if the dns master goes down the secondary slave can take over the job. If you have a firewall the port 53 must be set to open for DNS lookups and transfers UDP – TCP. To administer DNS server remotely port 135 is to be opened but this is a bit like having no belt on your trousers. You will have to assigne a static IP address in the advanced TCP/IP settings, pointed to itself for appliying DNS resolution.

This dns windows 2003 tutorial video covers the installation.

Linux iwconfig mode and iwconfig key’s.

2009-08-23T01:11:00.000-07:00

What is iwconfig it’s a wireless network interfaces for the Linux operating system for configuring the interface parameter settings on a network. This is nearly the same as ifconfig 8 but this iwconfig wireless is not for lan networks, only Wireless Application Protocol (commonly called WAP).
To start iwconfig access go to the open a terminal Linux window and then type : iwconfig this will the display the iwconfig settings parameters wireless statistics. To see the full view of all the iwconfig commands information type : man iwconfig there are a couple of extra ones that don’t always show up for the people that are trying to get around no follow, how ever but still accessible.

iwconfig wlan0 enc key : Sets scrambling keys the WEP encryption key in hex digits as XXXX-XXXX-XXXX-XXXX or XXXXXXXX. iwconfig eth0 key s:password [2],iwconfig eth0 key [2],iwconfig eth0 key open, iwconfig eth0 key off.
iwconfig wlan0 mode managed: configures the mode to managed for of multiple roaming Access Points.
iwconfig eth0 mode Ad-Hoc: is master backup mirror.
iwconfig wlan0 enc channel 7: Sets the network card to output on the 7th channel.
iwconfig essid driveon: controls the ESSID/SSID settings of driveon

If you you live in a place with numeruos other Wireless nodes, with high output antenna yogi aerials proving great distance communicationat a high power, its best to incoperat the RTS handshaking attribute. iwconfig wlan0 rts 64 -iwconfig wlan0 frag 256 This will change the packet transfer size.

How to bind.

2009-08-12T02:53:00.000-07:00

How to bind with the implementation of the bind 9 packages a name server this is one of the more popular ones applied in the majority of the server machines deployed on the Internet. This has been available from the 1980's under the free BSD licensing. bind is a very good system apart from a number of small problems in the security to how bind has been set-up. The configuring of the format in the simpler lookup DNS zone files are quit a strait forward task to apply. With the zone transfer on file greater than 16k can produce a glitches in the operating system of Windows 2000 DNS server. This makes the slave server to reject the zone file as incorrect data.

cache.dns

2009-08-04T12:27:00.000-07:00

DNS Cache Poisoning Attack the user types a web site into a browser that browser asks the local dns server for the address and takes the user to the desired website. A cache.dns files accommodates data with the IP addresses of all Internet root servers. DNS Cache has a retaining duration time, the time to live (dns ttl) after the TTL has expired it will delete the information. Local dns servers make this process faster for multiple queries they cash addresses so requests don’t go to the Internet every time you make a new request. If the request is not in the Cache the local dns server cashers it them performs forwarding on the request to the Internet root master dns server on the Internet. Internet security and researchers recently found a new method of attack on the open-architecture of the DNS Caching system exploiting its flaws.
By hackers sending a request to the local dns the query is then forwarded to the Internet dns next the attacker then floods the local dns with fake and non-authentic data response. Local dns server finds the malicious site in its cash and forwards the user to the malicious web site. Such attacks are called farming they send people to a site that contain tools for steeling information and putting viruses your computer.
There is a patch that can stop this from happening.

Protocol was developed to provide a lightweight authentication and
Integrity of messages between two DNS entities, such as client and
Server or server and server
TSIG record is sent without a secure key that code is executed which does not check the bounds of the data before storing it into a variable
“So don’t get in a pickle”

TSIG 'variables' RFC 2845

TSIG RR--- NAME Key name, in canonical wire format text
TSIG RR--- CLASS (Always ANY in the current specification)
TSIG RR--- TTL (Always 0 in the current specification)
TSIG RR RDLEN---
TSIG RDATA MAC---
TSIG RDATA--- Algorithm Name in canonical wire format strings encoded . using the syntax
TSIG RDATA--- Time Signed in network byte order
TSIG RDATA--- Fudge in network byte order 300
TSIG RDATA--- Error in network byte order 0 (NOERROR)
TSIG RDATA--- Other Len in network byte order 0
TSIG RDATA--- Other Data exactly as transmitted

Can you dig it….!

2008-10-22T23:49:00.000-07:00

Can you dig it.!

Dig (domain information groper) gateway is a flexible tool part for the DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server's that were queried. Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than dig.

Dig is used with command-line arguments; it has batch mode of operation as well to reading lookup request files. A brief summary of its command-line arguments and options is printed when the -h option is given. Unlike earlier versions, the BIND9 implementation of dig allows multiple lookups to be issued from the command line performing an NS query for "." (The root).
The default for dig via ${HOME}/.digrc. This file is read and any options in it are applied before the command line arguments.

Dedicated hosting server and domain name registry
Who do you pick..? When you pick your domain names you should find the domain names that are related to what your site is about and a top level domain names like .com if it is available. Domain name check is done to see if the domain name availability is ok and the name is free. After you got your name that you want, the domain name registry will hold your name and then it just needs pointing at your host server. Pick a well known host server e.g. Yahoo web hosting , MSN web hosting or a dedicated hosting Linux or host it yourself.

2008-10-16T19:39:00.000-07:00

What is DNS and BIND Domain Name System and Berkeley Internet Name Domain. (DNS) is the naming system for computers linking domain name locating and addressing. Just as you would look in your local directory to find a plumber..! Joining your site name e.g. www.mywebsite.com to the IP 123.123.345.256 on the server.
(BIND) was created by four graduate students from Berkeley in California. (BIND 9) is the new version of BIND but if your server does have heavy traffic then(BIND 8) is better for you to use. Now supporting the DNS Security Extensions. http://www.dnssec.net (DNSSEC)
