On BSD 4.2 we have been using FTP (in binary mode) to obtain TCP/IP performance numbers for traffic through various network configurations. These figures can be (and have been seen to be) impacted by internal FTP overhead and especially disk I/O bandwidth. What I want is one program which opens a TCP connection and sends blocks of data (data source) and another program which accepts a TCP connection and discards the data (data sink). The internet address, block size and block count should be program arguments. Both source and sink programs should calculate and display throughput statistics. These should be as simple as possible to minimize CPU loading. If anyone has anything like this or could be used as a starting point I would appreciate a copy. "Art Berggreen" ------
