linus c client program

hi,
what steps should i take to program a client that sends a .out file to a specific server .... where to start from ????

you really haven't provided enough information for us to give you advice.

we need to know:

how is the file generated?
what means of transferring the file do you want to use? tcp/ip, ipx, nfs, smb, etc.
what is the server supposed to do with the file when it receives it?
does the file transfer need to be secure? (encrypted)
is the file very large? does it need to be compressed before sending?
