vsftpd: 500 OOPS: could not bind listening IPv4 socket

Question

I will use vsftpd as a ftp server. I did all changes on /etc/vsftpd.conf.

These changes are (according to digitalocean):

anonymous_enable=NO
write_enable=YES
local_enable=YES
chroot_local_user=YES

More here: https://www.digitalocean.com/community/articles/how-to-configure-vsftpd-to-use-ssl-tls-on-an-ubuntu-vps

I'v also created a ssl certificate file. (not necessary but recommended)

Still getting :

500 OOPS: could not bind listening IPv4 socket

Note:

pam_service_name=vsftpd

Netstat:

netstat -pan|grep :21;
tcp        0      0 0.0.0.0:21 0.0.0.0:*               LISTEN      30694/vsftpd

Solution

Much probably you have /etc/xinetd.d/ftp enabled AND pointing to /usr/sbin/vsftpd and in /etc/vsftpd.conf you have listen=YES.

Simply change it to listen=NO. The listen=YES is for standalone, if you want vsftpd to be always active then you'll have to disabled it in the xinetd config.

Just curious... why not just use SFTP?

Sorry, already have.

do you use wrappers? i think xinetd can cause this as well... Sometimes some work on the wrappers is needed. It might help if you want to check to see if the port is taken by another service such as another ftp server by netstat.

Weird.. I wrote ftp.mysiteaddress and browser asked me to login with user info. I did but i got "No data received" error.
