大家好，又见面了，我是你们的朋友风君子。

Tcping 网上比较少资料是关于linux对tcp端口ping测试的方法，我这里简单介绍2种方法： 1.yum安装，编译安装方法 1-1.wget http://linuxco.de/tcping/tcping-1.3.5.tar.gz ###下载tcping

1-2 tar zxvf tcping-1.3.5.tar.gz ####解压缩tcping-1.3.5

1-3 cd tcping-1.3.5 ###进入文件夹

1-4 gcc -o tcping tcping.c ####编译执行文件

1-5 ./tcping www.baidu.com 80 ####使用方法，后面加tcp端口

2.通过shell脚本，执行tcping命令(能长ping) 2-1 脚本如下： #!/bin/sh

ver=”v1.7″ format=”%Y%m%d%H%M%S” d=”no” c=”no” C=”no” ttl=255 seq=0 q=1 r=1 w=3 topts=””

usage () { name=basename $0 echo “tcpping $ver Richard van den Berg ” echo echo “Usage: $name [-d] [-c] [-C] [-w sec] [-q num] [-x count] ipaddress [port]” echo echo ” -d print timestamp before every result” echo ” -c print a columned result line” echo ” -C print in the same format as fping’s -C option” echo ” -w wait time in seconds (defaults to 3)” echo ” -r repeat every n seconds (defaults to 1)” echo ” -x repeat n times (defaults to unlimited)” echo echo “See also: man tcptraceroute” echo }

_checksite() { ttr=tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $* 2>&1 if echo “${ttr}” | egrep -i “(bad destination|got roo)” >/dev/null 2>&1; then echo “${ttr}” exit fi }

_testsite() { myseq=”${1}” shift [ “${c}” = “yes” ] && nows=date +${format} [ “${d}” = “yes” ] && nowd=date ttr=tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $* 2>/dev/null host=echo “${ttr}” | awk ‘{print $2 ” ” $3}’ rtt=echo “${ttr}” | sed ‘s/.*] //’ | awk ‘{print $1}’ not=echo “${rtt}” | tr -d “.0123456789” [ “${d}” = “yes” ] && echo “$nowd” if [ “${c}” = “yes” ]; then if [ “x${rtt}” != “x” -a “x${not}” = “x” ]; then echo “$myseq $nows $rtt $host” else echo “$myseq $nows $max $host” fi elif [ “${C}” = “yes” ]; then if [ “$myseq” = “0” ]; then echo -n “$1 :” fi if [ “x${rtt}” != “x” -a “x${not}” = “x” ]; then echo -n ” $rtt” else echo -n ” -” fi if [ “$x” = “1” ]; then echo fi else echo “${ttr}” | sed -e “s/^.*.$/seq $myseq: no response (time out)/” -e “s/^$ttl /seq $myseq: tcp response from/” fi

echo “${ttr}”

}

while getopts dhq:w:cr:nNFSAEi:f:l:m:p:s:x:C opt ; do case “$opt” in d|c|C) eval $opt=”yes” ;; q|w|r|x) eval $opt=”$OPTARG” ;; n|N|F|S|A|E) topt=”$topt -$opt” ;; i|l|p|s) topt=”$topt -$opt $OPTARG” ;; f|m) ttl=”$OPTARG” ;; ?) usage; exit ;; esac done

shift expr $OPTIND – 1

if [ “x$1” = “x” ]; then usage exit fi

#max=echo “${w} * 1000” | bc

if [ date +%s != “%s” ]; then format=”%s” fi

_checksite ${topt} $*

if [ “$x” = “” ]; then while [ 1 ] ; do _testsite ${seq} ${topt} $* & pid=$! if [ “${C}” = “yes” ]; then wait $pid fi seq=expr $seq + 1 sleep ${r} done else while [ “$x” -gt 0 ] ; do _testsite ${seq} ${topt} $* & pid=$! if [ “${C}” = “yes” ]; then wait $pid fi seq=expr $seq + 1 x=expr $x – 1 if [ “$x” -gt 0 ]; then sleep ${r} fi done fi

exit

2-2 vi一个文件，这里命名为tcping

2-3 chmod 777 tcping ###赋予tcping执行权限

2-4 安装脚本执行内容所需软件支持

1.wget

2.rpm -ih tcptraceroute-1.5-0.beta7.el6.rf.x86_64.rpm

2-6 ./tcping www.baidu.com 80 ####执行shell脚本
