winSCP não listando o problema do diretório

Question

Estou tentando usar o winSCP para FTP meu servidor usando FTPs e, em seguida, sincronizar com uma pasta de backup. Eu tive esse trabalho bem de um PC na minha intranet de trabalho (ou seja, o mesmo domínio) no entanto, quando eu tento configurá-lo fora do site (que é o meu ponto inteiro) o mesmo script falhar. O log de FTP é o seguinte:

Isso falha se eu executo a partir da GUI ou de uma versão com script testada e em funcionamento anteriormente. Parece a partir do log como há um problema com um tempo limite na listagem de diretório, presumivelmente ele trabalha localmente como menos lag

Alguma idéia se esta é uma configuração do winSCP (e se sim onde) ou no lado do servidor de FTP (Windows Web Server 2008 R2)?

    

Answer 1

Eu encontrei este problema quando esqueci de abrir as portas extras que o modo Passive FTP requer.

Basicamente, você precisa abrir / permitir um intervalo de portas através do seu firewall, além da porta 21 que você já abriu.

Parece que você está usando o servidor FTP da Microsoft. A Microsoft tem uma página de suporte com instruções aqui .

Quando fiz isso, abri a porta 21 para a porta de controle e depois escolhi arbitrariamente as portas 65000-65050 para os dados de FTP passivo. Seu alcance variará com base no número de usuários / sessões simultâneos que você precisa ou espera (mais usuários / sessões simultâneas exigem mais portas abertas) e quaisquer outras portas que já estejam abertas para outros aplicativos.

    

Answer 2

tropeçou em mim mesmo. Muitas páginas têm a mesma pergunta, mas muitas vezes não a resposta (completa). São as portas PASV que precisam ser acessadas no modo PASV. Isso pode precisar que o firewall / IPtables sejam ajustados:
