vsftpd error - "fail to open directory" - slow progress

[Bob Hartung]

Hi,
  I am making progress on vsftpd but have hit a hurdle.  This is on a 
protected in house network. No open internet link.
  I can log in as anonymous.  I do not see /var/ftp/pub directory.  If I 
try a "ls" command I receive the following error:

       150 Here comes the directory listing.
       226 Transfer done (but failed to open directory.)

vsftpd.conf contains:
     anon_root=/var/ftp/pub
     anonymous_enable=YES 
     write_enable=YES
     anon_mkdir_write_enable=YES
     anonymous_enable=YES
     no_anon_password=YES
     write_enable=YES
     listen=YES
     nopriv_user=ftpsecure

I have changed the owner and group of the /var/ftp and /var/ftp/pub 
directories to ftpsecure.
The /var/ftp/pub directory contains several files that I do not see 
after loging in.  All are world readable.

For a while I was wondering if there was a second vsftpd.conf file being 
read, but I changed the banner
line and this chage was reflected when I logged in. 
    
Ideas? Suggestions?

Thanks

Bob
