查看IP连接数
netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
top -n 1 -b |grep 'httpd' |awk 'length($9)>=100.0{print "kill", $1}'|sh
netstat + awk 查询连接数两种方法，意义相同
1：netstat -pnt | awk '/^tcp/{print $5}' | cut -d: -f 1 | sort -n |uniq -c
2：netstat -pnt | awk '/^tcp/{s=split($5,N,":");A[N[s-1]]++} END{ for (k in A) print k,A[k]}'
