Servidores wirelesspt

Em informática, um servidor pode ser uma aplicação de software, computador ou ambos, com sistema de computorizado centralizada que fornece serviços a uma rede de computadores, chamada de clientes. Esses serviços podem ser de naturezas distintas, como por exemplo, arquivos, correio electrónico, partilha de ficheiros, alojamento web, etc.

Por razões de segurança, custo e privacidade, o projecto wirelesspt.net usa, cria, fornece e gere a maior parte dos seus próprios servidores para alojar os conteúdos do projecto.

A escolha do hardware é feita de acordo com as necessidades e maior parte do alojamento é feito por cmsv de forma privada. Este artigo visa em dar detalhes de alguns dos servidores utilizados.

Serviços

O projecto wirelesspt.net aloja nos seus servidores os seguintes serviços:

httpd, sql database, ircd, sftp, ssh, ntpd, rsync, distcc, murmur/mumble, bitlbee, eggdrops, cups, tor relays, gentoo binhosts, jogo frozen bubble, shoutcast/icecast.

Asus eeepc 1015

Por razões de hardware, consumo eléctrico, durabilidade e robustez os netbooks eeepc são bastante apreciados. O hardware em baixo descrito aloja o projecto wirelesspt.net desde 02/04/2012 substituindo alojamento pago na ovh que se demonstrou ser precário ao ponto de deixar de ser viável. O alojamento desde servidor é gratuito e situa-se no continente americano tendo-se mantido sem problemas nenhuns de alguma natureza excepto a substituição de uma ventoinha de arrefecimento do cpu ao fim de 4 anos e funcionamento.
