Testing SocketChannel NIO

I just wrote some NIO-code and wonder how to stress-test my implementation regarding

• SocketChannel.write(ByteBuffer) not able to write the whole byte-buf开发者_StackOverflow社区fer
• SocketChannel.read(ByteBuffer) reading the data in chunks into ByteBuffer

are there some simple linux-utilities like telnet to open a ServerSocket with some buffering-options?

Try original W. Richard Stevens' sock, it gives you ton of options.
