Registros DNS (DNS Registers)

Address (IPv4 A) Record:
 Estos se utilizan para traducir los nombres de dominio en direcciones IP.

AAAA (IPv6) Record:
El registro de la dirección IPv6 es un espacio de direcciones mucho más grande que el de un registro de la dirección IPv4. Las direcciones de registros de direcciones IPv6 tienen 128 bits de largo, mientras que las de IPv4 registros de direcciones tienen 32 bits de longitud.

Cuando usted recibe su nombre de dominio con una empresa de hosting, usted contará con una dirección IPv4 o una dirección IPv6. Esto necesita ser configurado como un registro o un registro AAAA respectivamente, para que el nombre de dominio en particular. Con Abaco Hosting cuenta con un panel de control detallado con estas funciones. Evite el registro de dominio con empresas terciarias que no le permiten el manejo de su zona dns.

Mail Exchanger (MX) Record:
Un registro MX identifica el servidor de correo electrónico (s) responsable de un nombre de dominio. Cuando se envía un correo electrónico a usuario@dominio.com, su servidor de correo electrónico debe primero busca el registro MX para sudominio.com a ver qué servidor de correo electrónico en realidad se encarga de correo electrónico para sudominio.com (esto podría ser mail.sudominio.com o algún otro correo electrónico servidor como mail.isp.com). A continuación, busca el registro para el servidor de correo electrónico para conectarse a la dirección IP.

Un registro MX tiene una serie de preferencias, lo que indica el orden en que se debe utilizar el servidor de correo electrónico. Servidores de correo electrónico intentará entregar el correo electrónico al servidor con el número más bajo de primera preferencia, y si no lo consigue continuar con el más bajo, y así sucesivamente.

Canonical Name (CNAME) Record:
Los registros CNAME son alias de nombres de dominio. A menudo los ordenadores en Internet tienen múltiples funciones como el servidor Web, servidor FTP, servidor de chat, etc. Para ocultar esto, Registros CNAME se puede utilizar, por poner nombres de los equipos individuales múltiples (alias).

A veces las compañías registrar varios nombres de dominio para sus marcas de fábrica, pero todavía desea mantener un único sitio web. En tales casos, un registro CNAME tal vez puede utilizarse para reenviar tráfico a su sitio web actual.

Ejemplo:

www.sudominio.com  podría ser CNAME para www.sudominio.net.

El uso más popular del Registro CNAME, es facilitar el acceso a un servidor Web que utiliza tanto la norma www.yourdomainname.com y yourdomainname.com (sin www). Esto suele hacerse mediante la adición de un registro CNAME para el nombre www apuntando al nombre corto [al crear un registro A para el nombre más corto (sin www)].

Los registros CNAME también se puede utilizar cuando un equipo o servicio tiene que ser renombrado, para permitir temporalmente el acceso a través de tanto el nombre antiguo y nuevo.

Who using my port 80/8080/8085/Other?

Windows Plataform

> netstat -aon  | grep "LIST"
> netstat -aon  | grep ":80" | grep "LIST"

*Get pid (Process id) and execute next command

>tasklist | grep "xxxx" 

* xxxx is pid value

Resume for W7


>netstat -aon  | grep ":80" | findstr "LIST"
>tasklist | findstr "xxxx" 
Linux Plataform
#lsof

or

#netstat -tulpn | grep :80

..continue


Notes:
If you mean MS-DOS then there's only FIND, as far as I know. But it's an ancient OS not used anymore.
If you mean NT(XP/2K/7/Vista)'s Command Prompt you can use find, findstr and grep if you download GnuWin32.
The basic differences are that findstr has some regex support. Grep supports regex best.

Trying Mount W7 Image (Ghost) over VMWare

Problem:
I need start Virtual Machine with W7, so  i don't have DVD Installer, but i have W7 image (created with Norton Ghost).

I Think make one iso file with W7 image for mount that, next mount ghost boot tool for restore from W7 iso file, but ghost not read files from iso mounted.

One alternative is mount USB as Hard Disk, but now my usb have only 4Gb (image file is ~ 7Gb )
I Think too mount iso image over virtual drive using winmount http://www.winmount.com/winmount-free.html


 VMware vCenter Converter StandAlone (tool for convert your physical computer to virtual machine)

thinking more, then i choice one solution very very crazy.

I try shrink my physical partition for add one aditional partition using Computer Management, Disk Managment (10Gb), then attach that new partition on VMWare Disk and try  restore image with Ghost.

So,  Microsoft Windows Server 2008 R2 – Media is write protected. For resolve that you need execute next commands.

cmd
diskpart 
list disk
select disk N
attributes disk clear readonly


* Too i try put .gho file into .iso for mount then restore, for that i need use iso editor, por example poweriso:
http://www.poweriso.com/download.htm  (v5.6)
Name: TEAM CRUDE
Key   : MIT68-I7WLE-CAGZN-DJYPR-PVNE4

* Alternatives

* Ghost32 ( For Convert .gho to .vmdk )

Nucom model R5000UNv2 Settings (Enable VNC ports by telnet)

Problem:
I need open vnc port 5900/5901 but i don't acces to GUI console(Web), only i have access to network by ssh. Then i need login to router and try set that with commands.


Syntax:

natp add <name> <WAN Interface> <TCP/UDP|TCP|UDP> <External Port(start:end)>
              <Internal Port(start:end)> <ipaddr>

 
#telnet 192.168.1.1


> wan show   # for show wan interfaces

> natp show table # for show current settings

> natp add vncport ppp0 TCP/UDP 5901:5901 5901:5901 192.168.1.100

ready!

Notes:
* Try use TP-Link W8960N for bandwidth control.
* If router mac is AABBCCDDEEFF try use BBAADDCCFFEE and user admin (Probably work)
