少しだけ突っ込んだ話。 （曖昧さは人間の脳内補完に委ねるとして･･･。） LinuxにはTCPの3Wayハンドシェイク（即ち、SYN,SYN/SCK,ACK）状態保持に関連して、 次のようなパラメータを持っている。 net.ipv4.tcp_max_syn_backlog=1024 何それ？って人は # sysctl -a | grep tcp 等のコマンドで探します。 # sysctl -a | grep backlog？それじゃノイズが無さすぎて面白くｎ(ry これは、「LinuxがSYNを受信し、SYN/ACKで応答した状態をいくつ保持するか」というもの。 閾値を超えると、Linuxは新規に接続しようとするホストのリクエスト（SYN）を無視する。 最近のLinuxを、最近のハードウェアにとりあえずインストールすると、 初期値は上記のような1024とか言う数値になっていると思う。 利用
