ftpvsftpd

FTP server connection connected but not responsive

I'm setting up an FTP server using vsftpd. To test it I have made an FTP connection using ftplib:

connection = ftplib.FTP(host)
connection.login(user=username, passwd=password)

And checked that it's connected using: 

connection.voidcmd("NOOP")

However, executing nearly anything doesn't seem to work. For instance:

connection.nlst()

Waits forever and then times out.

Connecting through ftp (ubunut) I see the message:

Entering Passive Mode (0,0,0,0,xxx,xxx).

Filezilla does work, how can this be?

Solution

  • The problem is that the passive connection isn't working. This can be because:

    1. the passive address isn't defined in the vsftpd.conf: pasv_address=`
    2. both listen and listen_ipv6 are defined in the vsftpd.conf

    Just in case, also check if the passive ports aren't opened under the firewall rules
