DE REPENTE, meu bubbleupnpserver não consegue se conectar na porta 58050 para http e 58051 para https. Ontem estava funcionando, sem alterações no servidor, puff, hoje não funciona mais. Talvez seja fail2ban? Erros:
HTTP: ERROR: Cannot connect. Check that the public host name is valid and that port 58050 is opened on your router
HTTPS: ERROR: Cannot connect. Check that the public host name is valid and that port 58051 is opened on your router
Aqui está a saída do iptables:
sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere ns375259.ip-5-196-88.eu tcp dpt:58051
ACCEPT tcp -- anywhere ns375259.ip-5-196-88.eu tcp dpt:58050
f2b-sshd tcp -- anywhere anywhere multiport dports s sh
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain f2b-sshd (1 references)
target prot opt source destination
RETURN all -- anywhere anywhere
Como sugerido, em netstat -tulpn encontrei 2 entradas com essas portas e fica assim:
tcp 0 0 0.0.0.0:58050 0.0.0.0:* LISTEN 1455/java
tcp 0 0 0.0.0.0:58051 0.0.0.0:* LISTEN 1455/java
