Number of bytes is relatively easy -- see the obytes64 and rbytes64 kstats. Number of connections is not well defined. TCP/IP doesn't quite work that way. Connections are transport-layer entities (e.g., TCP), while interfaces are network-layer entities (IP). Conceptually, a given TCP segment for a given connection will be converted into a datagram by IP, and then IP will determine, on a packet-by-packet basis, where to send that individual datagram. Although in a given environment, it may be the case that some (or even "many") connections appear to send and receive packets over only a single interface, there really isn't any sort of useful or stable mapping of connection to interface. -- James Carlson 42.703N 71.076W <[email protected]> _______________________________________________ networking-discuss mailing list [email protected]
