<p>Pra quem quer implementar uma forma mais simples do que indicar os domínio usados pelo Mensageiro Maldito da Microsoft essa é a maneira mais simples.<br />
Bastar criar uma acl da seguinte forma:<br />
<strong><br />
acl msn rep_mime_type -i ^application/x-msn-messenger$</strong></p>
<p>E mandar um:</p>
<p><strong>http_access deny msn</strong></p>
<p>Mas o pior de tudo isso é que você vai ter que colocar alguma implementação no squid como o SquidGuard para bloquear também os malditos webmessengers que conectam no msn direto pelo navegador (dã!). Existem listas por aí, bastar ficar atento porque todo dia aparece um site pra isso.</p>
<p>Em breve mando mais dicas para bloquear definitivamente &#034;isso&#034; que chamam de protocolo de IM.</p>

			<content:encoded><![CDATA[<p>Este tutorial mostra como você configura o firefox, o synaptic, o apt-get e a rede para trabalhar apropriadamente por trás um proxy com o ubuntu 9.10 karmic koala:</p>
<p><strong><span style="text-decoration: underline;"><span style="font-size: medium;">I-Usar o Firefox sob um proxy:<br />
</span></span></strong></p>
<p>Abra seu firefox e vá até Editar &gt; Preferências</p>
<p><img class="alignnone" src="http://i671.photobucket.com/albums/vv77/ZINOVSKY/firefox.png" alt="" width="567" height="553" /></p>
<p>Agora até Avançado &gt; Rede &gt; Configurações</p>
<p><img class="alignnone" src="http://i671.photobucket.com/albums/vv77/ZINOVSKY/advace.png" alt="" width="567" height="553" /></p>
<p>Em<strong> proxy manual</strong> insira o servidor proxy e a porta</p>
<p><img class="alignnone" src="http://i671.photobucket.com/albums/vv77/ZINOVSKY/prxy-fire.png" alt="" width="500" height="535" /></p>
<p>Agora clique em ok, reinicie o firefox e verifique se você consegue navegar na internet <img src='http://www.ubuntu-ac.org/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' />  se o proxy tiver autenticação será solicitado o usuário e senha para o acesso</p>
<p><span style="text-decoration: underline;"><strong><span style="font-size: medium;"><span style="color: #000000;">II-Configurando o Gerenciador de Pacotes Synaptic por trás de um proxy</span></span></strong></span></p>
<p>Na barra principal do GNOME vá até Sistema &gt; Administração &gt; Gerenciador de Pacotes Synaptics. Ao abrir vá até Preferências &gt; Rede<br />

</span></p>
<p><span style="color: #000000;">Em autenticação você pode inserir o usuário e a senha se for necessário. Aplique as alterações e clique em ok.<br />
</span></p>
<p>Agora recarregue o Synaptic clicando no botão recarregar no canto superior esquerdo e veja se consegue instalar seus pacotes.</p>

</span></p>
<p><span style="font-size: large;"><span style="font-size: small;">Edite este aquivo a seguir usando o comando sudo   /etc/bash.bashrc  (Use algum destes editores após o <strong>sudo</strong>:Vi nano ou  gedit)</span></span></p>
<p><span style="font-size: large;"><span style="font-size: small;">e adicione<br />
</span></span></p>
<p><span style="font-size: small;">export http_proxy=http://username:pass@host:port/<br />
</span></p>
<p><span style="font-size: small;">export  ftp_proxy=http://username:pass@host:port/</span></p>
<p><span style="font-size: small;">onde:</span></p>
<p><span style="font-size: small;">username: nome do usuário</span></p>
<p><span style="font-size: small;">pass: senha do usuário</span></p>
<p><span style="font-size: small;">host: nome ou endereço IP do seu servidor proxy</span></p>
<p><span style="font-size: small;">port: a porta do seu servidor proxy<br />
</span></p>
<p><span style="font-size: small;">Para efetuar as alterações é necessário reiniciar o micro.<br />
</span></p>
<p><span style="font-size: medium;"><span style="text-decoration: underline;"><strong>IV-Configurar o proxy da rede</strong> </span></span></p>
