Você tem uma máquina em casa com Banda Larga? Speedy ou outra qualquer?

Você deseja acessá-la de qualquer outra máquina mas não sabe como? Qual o IP da sua máquina nesse momento?

Uma forma seria anotar o IP da sua máquina que o site www.showip.com mostra.

Outra forma é utilizar o DynDNS que fica responsável pela atualização frequente do seu IP.
E para acessá-la basta digitar o endereço que você escolheu no site www.dyndns.com.
Daí fica fácil!! E sua máquina pode estar tanto no Windows quanto no Linux, tanto faz, basta instalar o software client fornecido pelo site e pronto!

Como eu devo proceder?

Primeiro acesse o site https://www.dyndns.com e faça o seu cadastro. Anote seu login e sua senha.

Depois acesse o

DDCLIENT v3.6.7

ddclient is a Perl client used to update dynamic DNS entries for accounts
on many dynamic DNS services.

IMPORTANT: The format and options used by ddclient have CHANGED.
Please examine the sample configuration file.
It is highly recommended that you take advantage of the
new daemon mode of operation.

IMPORTANT: The installation location for the ddclient script has changed from
/root/bin/
to
/usr/sbin/
