Thanks for the reply, the vsftpd server started ok, and i add the ports 21 and 20 to the shorewall firewall rules to accept the connections from the net to the firewall, but still ftp client cannot connect to vsftpd server:
[user]$ lftp -u user
asswd
ftp://example.com
lftp
user@example.com:~> ls
`ls' at 0 [Delaying before reconnect: 43]
I check the /var/log but there is no any vsftpd.log, this is my vsftpd.conf:
vsftpd.conf
Thanks for your help in advanced.
