A TCP socket is a 4-tuple of localhost:localport:remotehost:remoteport A given localhost:localport pair can speak to an unlimted array of remotehost:remoteport sets. For example, in theory, your SMTP port can get connections from up to 2^32 different hosts on each of 2^16 different sockets from each, for a total space of 2^48 connections to a single local socket number. This in no way restricts how many connections can come in to another port, either, because a given socket is again the full 4-tuple -- if you have an SSH port, it too can get 2^48 connections. Now, there is this (odd) convention that only root can open a socket below 1024, so hosts "trust" (what a bad idea) sockets under that number. You can still, however, get up to 1023 connections from any given remote host to a given local host's port. Thus, your problem sounds rather odd. There is no obvious reason you should be limited to 360 connections. Perhaps your problem is not what you think it is at all. Could you explain it in more detail? -- Perry E.
