Replacing NIC with own C programs.
Iam assigned a task to develop a tool which will transfer files from one system to another connected using the ethernet but there wont be any interface card. I hav to write the C programs that will do the tasks of identifying ports n sockets,assigning addresses, appending headers and performs checksums. Right now Iam in complete darkness 'coz I dont know the next step. So plz help me if u hav any idea about this task and where i can get some material or working model. Thx
