The tftp server mentions little problems like files not found. So to does xinetd complain if it finds a problem lsof (or netstat) to tell you whether something's listening: [root@xxxxxx root]# lsof -c x -a -i COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME xinetd 913 root 5u IPv4 1759 TCP *:pop3 (LISTEN) xinetd 913 root 6u IPv4 1760 TCP *:rsync (LISTEN) xinetd 913 root 7u IPv4 1761 UDP *:tftp xinetd 913 root 9u IPv4 1762 TCP *:time (LISTEN) [root@xxxxxx root]# The tftp client which _may_ have more intelligence than your board: # 192.168.0.99 does not exist here: Numbat:~# tftp 192.168.0.99 tftp> get fred Transfer timed out. tftp> quit # 192.168.1.1 exists, but there's no tftp server there Numbat:~# tftp 192.168.1.1 tftp> get fred Transfer timed out. # Magpie is my working server tftp> Numbat:~# tftp magpie tftp> get fred Error code 1: File not found tftp> Numbat:~# logout Connection to Numbat closed. summer@xxxxxx:~$ tcpdump which is excellent for snooping traffic on your LAN. -- Please, reply only to the list.
