VSFTPD UBUNTU ROOT无法登录问题

/etc/ftpusers

把ROOT删掉

查看端口是否被占用

netstat -ntpl|grep 21

查看服务状态

service vsftpd status

发现

Jan 19 18:37:47 iZ2ze373wamkt3i3yfqt52Z systemd[1]: Starting vsftpd FTP server...

解决

谢谢！我在vsftpd.conf中找到两个监听ipv4 和ipv6的
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=NO
把listen改成NO成功启动了

总结

操他姥姥大爆炸！！折腾1个多小时
