i got this application from http://sourceforge.net/projects/tftp/ ...and i realise to bind the server but i cant use the client or i dont know how...can somebody help me...im sure it takes just few minutes for someone who knows

Welcome to LinuxQuestions
It would help to know what linux distribution / version you are running and what you are trying to accomplish. Did you successfully install the server and client applications?

Many distributions already include the client and server. All you have to do is enable the server in xinetd.d and restart xinetd.

Daemon Successfully forked (pid: 5525)
i can fork the server but when i try to use the client....i get this :
mihai@ubuntu:~/Desktop$ ./tftpc
Usage:
./tftpc server [-h] [-d] [-P port] [-g] | [-p] [file-name] [-w size] [-l length] [-o] [-n]
Options:
-h (help; this message)
-d (Debug mode)
-P port(Port number default is 69)
-g (get a file from the server)
-p (send a file to the server)
-w size (set window size, default is 1)
-l len (set max packet length, default is 512 bytes)
-o for octet file transfer (default).
-n for netascii file transfer
mihai@ubuntu:~/Desktop$ sudo ./tftpc tftpd -h
[sudo] password for mihai:
Client could not get host address information: Connection timed out
mihai@ubuntu:~/Desktop$
And i use ubuntu 9.04

server is the name or IP address of the computer where tftpd is running. i.e.
./tftpc localhost -g filename

This would get the file called filename. Copy a file to your tftp directory and then try the command. Make sure you replace filename with the actual file you copied.
