Pb IPv4 sous serveur FTP FEdora 4

[albinpopote]

Bonjour

j'ai configuré le protfpd.conf et le /etc/xinetd.d/xproftp pour faire de mon pc un serveur ftp ! mais le problème, quand je le test en telnet localhost 21 j'ai un message d'erreur :

telnet localhost 21

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

500 OOPS: could not bind listening IPv4 socket

Connection closed by foreign host.

Pourquoi cela ne fonctionne pas ?

Regarde dans /var/log/messages, tu auras plus d'infos.

tu y vois une raison ?

[albinpopote]

Il est possible que je sois en IPv6 par défaut et non IPv4 ? cela pourrait-il me créer le pb ?

[fabien29200]

Dans terminal tape :

# ifconfig

Si tu vois qqchose dans le genre :

eth0 Link encap:Ethernet HWaddr 00:40:D0:71:88:11

inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0

C'est que tu as une IPv4.

[albinpopote]

donc je suis bien en IPv4 !

[fabien29200]

Tu as une erreur : "Address already in use".

Ce qui veut dire que le port 21 de ton serveur est déjà utilisé... Soit ton serveur est déjà lancé soit un autre logiciel est lancé sur ce port ...

Qu'y a-t-il dans le fichier de configuration de Proftpd ?

bon alors apparement le problème viendrai du fait que proftp et vsftpd était tous les deux installé sur mon linux et que cela faisait un conflit !

Après avoir supprimé vsftpd, relancé xinetd et refait un test , je n'ai plus l'erreur IPv4 !
