Eu instalei proftpd em uma máquina Centos 7.
Esta é a saída de systemctl -l status proftpd :

Todos os comandos start , stop e restart funcionam bem, sem exibir nenhum erro.
Eu verifiquei a configuração com --testconfig e ele não exibe nenhum erro. Enfim, aqui está o arquivo completo proftpd.conf , embora eu não tenha alterado nenhuma opção, então é estranho que não esteja funcionando caixa.
Não há registros em /var/log/proftpd/ . /var/log/messages/ mostra apenas as mesmas linhas que systemctl status faz.
Não há regras de firewall:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Ainda assim, não consigo usar netcat para conectar na porta 21, mesmo a partir do localhost. E netstat -tulpn | grep :21 não mostra nenhuma saída.
Aqui está a saída de proftpd -V :

Estou perdido e não tenho ideia sobre como resolver ainda mais o problema. Eu também removi e reinstalei o pacote, mas isso não mudou nada.
