如何查看已記錄IP地址的次數(shù)？我的想法是這樣的192.168.1.254192.168.1.254192.168.1.254192.168.1.254192.168.1.25410.40.89.79對(duì)此192.168.1.254（5）10.40.89.79（1）syslog_2019-05-15.txt看起來(lái)像這樣DROP IN = eth0 OUT = MAC = 38：2c：4a：cb：e2：40：10：e8：78：aa：89：ba：08：00 SRC = 92.53.90.242 DST = 90.149.222.18 LEN = 40 TOS = 0x00 PREC = 0x00 TTL = 243 ID = 37773 PROTO = TCP SPT = 59155 DPT = 1027 SEQ = 1687374236 ACK = 0 WINDOW = 1024 RES = 0x00 SYN URGP = 0 192.168.1.1 5月14日00:01:44 kern警告內(nèi)核DROP IN = eth0 OUT = MAC = 38：2c：4a：cb：e2：40：10：e8：78：aa：89：ba：08：00 SRC = 185.216.140.6 DST = 90.149.222.18 LEN = 40 TOS = 0x00 PREC = 0x00 TTL = 248 ID = 54321 PROTO = TCP SPT = 5碼：var fs = require('fs');fs.readFile('C:/Users/sondr/Desktop/koder/Ip_s?k_syslog/syslog_2019-05-15.txt', 'utf8', function(err, data) {   if (err) throw err; {     //count     var count = 0;     //ReEX     const reg = /\bSRC=([\.0-9]+)\b/g;     while ((m = reg.exec(data))) {       console.log("SRC= " + m[1])       console.log(++count);     }     // DEBUG:     //console.log(data);   }});
