[CentOS] Problema VSFTPD
ho seguito la procedura per l'installazione di VSFTPD, senza alcun genere di problemi, e pare che funzioni solo dalla macchina dove gira il processo, dalla rete locale non funziona.
non è un problema di collegamento o configurazione della rete perché ho testato HTTPD e funziona senza problemi, il firewall è disattivato quindi non so che dire. ![]() la procedura l'ho presa da qui: http://www.unixmen.com/install-confi...erver-centos-7

cela fai a incollare qui il file di configurazione:
/etc/vsftpd/vsftpd.conf per vedere messaggi di errore del servizio: systemctl status vsftpd per vedere messaggi di errore generali: journalctl -b p.s. con: netstat -anp|grep :21 dovresti vedere la porta ftp aperta Ultima modifica di sacarde : 31-08-2015 alle 20:48. |

rispondendo a gianmpu:
funziona, dice: connected to .......... 220 welcome to blah ftp service rispondendo a sacarde: questo è il contenuto di vsftpd.conf: Codice:

Se riesci a connetterti dal client, il servizio funziona.
Quando inserisci username e password, li accetta? Inviato dal mio GT-N5100 utilizzando Tapatalk

Una domanda (forse) stupida. Il client che cerca di connettersi al server che indirizzo ha?

logicamente diverso da quello del server ma fa parte comunque della stessa rete, facendo ping client>>server non ci sono problemi, infatti nel primo messaggio avevo detto che c'era httpd funzionante

a quanto pare è il firewall il problema, all'inizio non riuscivo spiegarmi come da disattivato potesse interferire, l 'ho attivato e per un certo periodo ha accettato la richiesta ftp
![]() ![]() ora l'ho disabilitato con: Codice:
systemctl stop firewalld Codice:
systemctl disable firewalld
