Hi Li,

You result description ment nothing to me.  Please cut & paste real 
messages.  Are you typing "tftp 192.168.4.1" from your _host_ (linux 
server) command line?

OK, I ran a real instance on my home box (Debian 3.1 x86)

I was a little surprised that the tftp "get" worked with the /tftpboot 
full path.  On a different box that I used (RH), it is configured as "-s 
/tftpboot" for the option (rather than "/tftpboot") so tftpd treats 
paths as relative to /tftpboot and thus the get "/tftpboot/foo" won't 
work because there is no /tftpboot/tftpboot/foo on the server.  This 
should not be your problem since your configuration matches mine.

HTH,
