Eu tive um problema muito estranho durante a configuração do vsftpd na minha instância ec2: configurei o servidor ftp para usar ftp sobre TLS e funcionou bem no filezilla, porém não consegui me conectar usando nenhum módulo ftp de editores de texto (eu tentei com notepad++ e webstorm). Achei que talvez fosse o problema com o SSL, então mudei primeiro para FTP simples e inseguro e tentei fazê-lo funcionar. Agora os clientes FTP funcionam perfeitamente novamente (filezilla, comandante total), mas os editores de texto acima me dão o seguinte erro após a conexão bem-sucedida:
Failure retrieving contents of directory /
Tentei de tudo, mas por enquanto não tenho ideia de qual seria o problema. Aqui estão minhas configurações vsftp:
listen=NO
listen_ipv6=YES
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
chroot_list_enable=NO
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=ftp
ssl_enable=NO
pasv_enable=YES
pasv_min_port=1024
pasv_max_port=1048
port_enable=YES
pasv_address=[EC2_PUBLIC_DOMAIN]
pasv_addr_resolve=YES
Alguém tem alguma ideia de qual deveria ser o problema? Toda ajuda é bem-vinda. Obrigado.

Sábado, 14 de janeiro 20:01:38 2017 [pid 8103] [dev_back] Resposta FTP: Cliente "::ffff:178.48.165.229", "227 Entrando no modo passivo (0,0,0,0,4,2)."
Isso parece um bug do servidor FTP vsftpd, quando o público pasv_addressestá definido e o servidor possui um endereço IPv6 (local) (como é o caso do EC2).
Postei mais sobre o bug na pergunta Server FaultResposta passiva do Vsftpd com endereço 0,0,0,0 mesmo com pasv_address correto.
FileZilla pode ignorar o endereço IP inválido:
14/01/2017 21:27:42 4856 1 Resposta: 227 Entrando no modo passivo (0,0,0,0,4,12).
2017-01-14 21:27:42 4856 1 Status: Servidor enviou resposta passiva com endereço não roteável. Usando o endereço do servidor.
Mas o Notepad++ não pode.
