Como posso obter mais informações do Curl sobre um erro FTP “Não é possível abrir a conexão de dados”?

Question

Estou tentando fazer upload de um arquivo com a seguinte linha:

curl -3 --ftp-pasv --ftp-ssl-control -v -i -T ./mybigfile.gz ftp://[email protected]:21/OnlineBackup/Lawrence/ --insecure -u 'zzzzzzz:YYYYYY'

Mas recebo um erro de protocolo - mas não tenho ideia do erro, como posso obter mais informações?

Answer 1

Houve um problema com seu computador se conectando ao servidor na porta 63307 , possivelmente um firewall em algum lugar.

Certifique-se de que todas as portas > 1024 no servidor estão acessíveis ou garantem que o cliente não esteja atrás de um roteador e todas as portas no cliente estejam acessíveis (não com firewall) e usem o modo ativo (se suportado pelo servidor).

Este link pode fornecer algumas informações - O cliente não conseguiu estabelecer uma conexão de dados por algum motivo (Conexão # 3 no diagrama passivo)
