The STK1000 Linux environment includes troll-ftpd, which is a freely available, small, but unsupported, FTP daemon from Trolltech AS. The FTP daemon is run from inetd, and is enabled by the following line in /etc/inetd.conf: 

ftp stream tcp nowait root.root /usr/sbin/ftpd ftpd

The FTP daemon allows anonymous FTP uploading and downloading of files in the /home/ftp directory. This can be used as a simple way to transfer programs and files to the STK1000.

To log in anonymously, enter ftp when asked for a user name: 

Connected to xx.xx.xx.xx.

220-Local time is now 01:16 and the load is 0.00.

Found this problem in 2.6.18-atngw you can check this with the following command 

~ # uname -a
Linux static-host 2.6.18-atngw #1 Fri Apr 27 13:45:58 CEST 2007 avr32 unknown


Try adding "-l -a" to the FTP control file /etc/inetd.conf :

From: 

ftp             stream  tcp nowait      root.root /usr/sbin/ftpd ftpd

To: 

ftp             stream  tcp nowait      root.root /usr/sbin/ftpd -l -a ftpd

File should like like this: 

ftp             stream  tcp nowait      root.root /usr/sbin/ftpd -l -a ftpd
#netbios-ssn    stream  tcp nowait      root.root /usr/sbin/smbd smbd
#netbios-ns     dgram   udp wait        root.root /usr/sbin/nmbd nmbd
swat            stream  tcp nowait.400  root.root /usr/sbin/swat swat
