vsftpd returns wrong pasv_address

Question

I use vsftpd on my CentOS6.4 home server. Recently I noticed that I can connect to the ftp but LIST command fails because vsftpd is returning wrong IP address when entering passive mode.

I figured out that I need to change vsftpd.conf from

pasv_address=my.domain.com

to

pasv_address=xxx.xxx.xxx.xxx (server's IP address)

to make it work.

Since my server's IP address is not static, I use a dynamic DNS service and the service is working fine. However, it seems vsftpd returns an old IP address as pasv_address.

Can anyone suggest why this happens and how to solve it. Thanks in advance.

Solution

Try putting the following line in your vsftpd.conf

pasv_addr_resolve=YES

Then you should be able to put a hostname instead of an IP address as the pasv_address ; pasv_addr_resolv defaults to NO

Worked perfectly. This should be the accepted answer.
