[laocai@laocai.com laocai]# ftp localhost
Connected to localhost (127.0.0.1).
500 OOPS: could not bind listening socket
ftp> quit

Can’t connect to vsftpd!!! Stupid ya…

Solution:

1. Edit /etc/vsftpd/vsftpd.conf
2. Remove/Comment listen=YES, ie: #listen=YES
3. Restart vsftpd: service vsftpd restart

Done!

p/s: vsftpd是unix/linux常用的ftp service

我的媽呀! 兩層的Bubble Sort!!
