Copying Files over a Socket

I want to copy files over a network reliably. The program I have works except for two things:
  • The socket connection should terminate after receiving the file. In runtime, the connection does not terminate. My guess is, the client is stuck in the for loop that reads the file from the network.
  • When I used a test file, numbering the lines from 1 to 1000 (each lines reads "[number] ----- L" ), I noticed about 60 extra lines at the end of the file. Probably this is because I read into and copy from 1024-byte arrays which don't totally get written over at the end of the file.

  • So, how do I detect the end of file when I am using byte arrays like this? Or is there an even bigger issue.
