Instalei o vsftpd e estou usando o ufw como meu firewall. Posso me conectar ao servidor FTP, fazer login e alterar diretórios, mas qualquer tentativa de usar um comando LIST expira tanto no host externo quanto no local. Ao ler outras respostas, sou levado a acreditar que isso se deve ao fato de minhas portas passivas não terem sido abertas corretamente. No entanto, pelo que sei, as portas estão abertas no ufw. Além disso, quando executo ufw disablee tento novamente, o problema ainda ocorre. O fato de isso acontecer no mesmo host do servidor me leva a acreditar que algo está errado no meu sistema.

Não sei mais o que tentar. Parece que o vsftpd simplesmente não está aceitando conexões nessas portas, embora eu as tenha especificado. Disposto a tentar qualquer coisa neste momento.
