VSFTPD notes:
You'll need to add line like
echo "ftp stream tcp nowait root /opt/sbin/vsftpd /opt/etc/vsftpd.conf" >>/etc/inetd.conf
 to your /unslung/rc.xinetd file
 -- see the wiki at http://www.nslu2-linux.org for more info

ftp 192.168.82.1
Connected to 192.168.82.1.
500 OOPS: vsftpd: cannot locate user specified in 'ftp_username':ftp
Connection closed by remote host.  

I now that from http://www.nslu2-linux.org/wiki/Unslung/Vsftpd that

* Problem: When trying to ftp into the slug, it gives a message 500 OOPS: vsftpd: cannot locate user specified in 'ftp_username':ftp"" 

Solution: Change the echo line in /unslung/rc.xinetd to: echo "ftp stream tcp nowait root /opt/sbin/vsftpd /opt/etc/vsftpd.conf" >>/etc/inetd.conf  

1. Create the empty jail directory as root with mkdir -p /usr/share/empty 
2. Ensure vsftpd.conf is in /opt/etc (the default vsftpd.conf is below) 
3. If you use the default vsftpd.conf make sure that /opt/var/log exists and is writable by vsftpd 
4. Create (or modify existing) diversion script /unslung/rc.xinetd . Previous suggestions were broken in that multiple lines could be added or other services, like telnetd, become disabled.
A good solution (not just for vsftpd, but for all applications needing entries in inetd.conf) seem to be: 
 
#!/bin/sh
# /unslung/rc.xinetd

if [ ! -f /etc/inetd.conf ] || !(grep vsftpd /etc/inetd.conf -q) ; then
  echo "ftp stream tcp nowait root /opt/sbin/vsftpd /opt/etc/vsftpd.conf" >>/etc/inetd.conf
fi

return 1 

1. Note: Make sure that the file /unslung/rc.xinetd file ends with the line "return 1" in order for inetd to be started when /etc/rc.d/rc.xinetd is executed 
2. Restart xinetd with /etc/rc.d/rc.xinetd 
3. Assure yourself that you use a linux compatible texteditor otherwise the CR/LFs? will be wrong and your ftp-server will not start!!
