portsnap fetch extract初回更新時用
portsnap fetch update以降の更新時に使用

FETCH_AFTER_ARGS=
DISABLE_SIZE=yes
netstat -n | awk '/^tcp/{++state[$NF]} END {for(key in state) print key,"\t",state[key]}'
netstat -nat|grep -i "80"|wc -l
サーバの統計:
1)統計80ポート接続数
netstat -nat|grep -i "80"|wc -l
1
2)httpdプロトコル接続数の統計
ps -ef|grep nginx|wc -l
ps -ef|grep php-fcgi|wc -l
1
3)、統計が接続されている、状態が「established」である
netstat -na|grep ESTABLISHED|wc -l
2
4)、どのIPアドレスが最も接続するかを調べ、それを封印する.
netstat -na|grep ESTABLISHED|awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -r +0n 
netstat -na|grep FIN_WAIT_1|awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -r +0n
netstat -na|awk '{print $5}'| sort | uniq -c | sort -r | awk -F' ' '{if ($1 > 50) print $2}'
Netstat TCP接続状況をすばやく確認
netstat -n | awk '/^tcp/{++S[$NF]} END {for(a in S) print a, S[a]}'
SYN_RCVDの意味はman netstatで理解できます.SYN_RCVDは現在完了していないTCP SYNキューを表します
