Hello guys, I really need your help.

Here is the question:

    I cannot connect to my unraid server via ftp.

    I have open ftp server and set user list in unraid GUI. When I try to connect to my server by using ftp command in windows cmd, it says

500 oops could not bind listening IPv4 socket

    I open unraid terminal, and port 21 is being listened by inted. Every time I try to connect, the unraid server log will add a new line, no more other message.

Mar 18 18:55:12 Tower vsftpd[26798]: connect from 10.0.0.11 (10.0.0.11)

    I try to use vsftpd in docker, and disable the ftp server in unraid GUI, it works. But I really want to use the origin ftp server.

What can I do?

By the way, I have tried to solve the problem by editing /etc/vsftpd.conf.

At first, it was a bland file. (the problem exists)

Now, here is its content:

connect_from_port_20=YES
# listen=YES
write_enable=YES
xferlog_file=/var/log/vsftpd.log
local_root=/mnt
local_umask=0
anonymous_enable=NO
local_enable=YES
userlist_enable=YES
userlist_deny=NO
userlist_file=/boot/config/vsftpd.user_list
check_shell=NO
syslog_enable=YES
log_ftp_protocol=NO
xferlog_enable=NO
dirmessage_enable=NO

When I put wrong parameter, the problem will change to "500 OOPS: unrecognised variable in config file", but when I correct the variable, the origin problem still exists.

Don't use the built-in FTP for access outside your LAN. Disable it and install one of the FTP from the Apps page

Thank you for the advice. I access via VLAN.

Do you have any suggestion about FTP app? I tried crushFTP, it was not free and easy to use.
