Port 8181 bloqué sur serveur Debian?

**josse34** · 22/10/2012, 09h46

Bonjour!

J'ai un soucis avec mon serveur sous Debian 6 Sqeeze 32bits & ISPconfig.

Tout les ports semblent ouverts sauf le port 8181, ma console SSH indique pourtant aucun parefeu, pas de Fail2ban et un IPtables comme ceci :

iptables -S (ipv4)
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-N fail2ban-courierimap
-N fail2ban-courierimaps
-N fail2ban-courierpop3
-N fail2ban-courierpop3s
-N fail2ban-pureftpd
-N fail2ban-sasl
-N fail2ban-ssh
-A INPUT -p tcp -m multiport --dports 25 -j fail2ban-sasl
-A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh
-A INPUT -p tcp -m multiport --dports 143 -j fail2ban-courierimap
-A INPUT -p tcp -m multiport --dports 995 -j fail2ban-courierpop3s
-A INPUT -p tcp -m multiport --dports 110 -j fail2ban-courierpop3
-A INPUT -p tcp -m multiport --dports 993 -j fail2ban-courierimaps
-A INPUT -p tcp -m multiport --dports 21 -j fail2ban-pureftpd
-A fail2ban-courierimap -j RETURN
-A fail2ban-courierimaps -j RETURN
-A fail2ban-courierpop3 -j RETURN
-A fail2ban-courierpop3s -j RETURN
-A fail2ban-pureftpd -j RETURN
-A fail2ban-sasl -j RETURN
-A fail2ban-ssh -j RETURN

ip6tables -S (ipv6)
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT

Comment ouvrir ce port?

Grand merci et bonne journée!!

Que retourne iptables -L -n -v ?

Re,

la politique par défaut pour la table filter est d'accepter tous les paquets, et il n'y aucun règles qui bloque le port 8181.

Quel est le programme qui est censé utilisé 8181 ?

Et que retourne la commande (en root) : netstat -anp | grep 8181 ?

Bonjour!

Quel est le programme qui est censé utilisé 8181 ?

Un simple code php avec un request Curl vers une adresse IP type xx.xx.xx.xx:8181

Et que retourne la commande (en root) : netstat -anp | grep 8181 ?

netstat -anp | grep 8181 et grep 8181 ne renvois rien

netstat -anp grep 8181 renvoi ceci :

Un simple code php avec un request Curl vers une adresse IP type xx.xx.xx.xx:8181

=> ok, comme ton par-feu accepte tout, et que tu est le client de l'ip xx.xx.xx.xx:8181,
alors le problème ne vient pas de ta machine, mais vient de la machine ip xx.xx.xx.xx:8181.
