[root@duyunlong-100-70test]# tcpcheck 数量 IP地址 连接状态 313 172.16.6.11 ESTABLISHED 189 172.16.6.13 ESTABLISHED 176 172.16.6.12 ESTABLISHED 64 172.16.100.50 ESTABLISHED 50 172.16.100.51 ESTABLISHED 43 172.16.3.20 ESTABLISHED 31 172.16.1.64 ESTABLISHED 31 172.16.1.62 ESTABLISHED 31 172.16.1.61 ESTABLISHED 30 172.16.4.20 ESTABLISHED 30 172.16.3.81 ESTABLISHED 30 172.16.3.80 ESTABLISHED 30 172.16.3.66 ESTABLISHED 30 172.16.3.21 ESTABLISHED 30 172.16.1.65 ESTABLISHED 30 172.16.1.63 ESTABLISHED 30 172.16.1.60 ESTABLISHED 30 172.16.1.103 ESTABLISHED 30 172.16.1.102 ESTABLISHED 30 172.16.1.101 ESTABLISHED
或者可以跟参数
[root@duyunlong-100-70test]# tcpcheck TIME_WAIT 数量 IP地址 连接状态 15 172.16.3.21 TIME_WAIT 15 172.16.3.20 TIME_WAIT 2 172.16.6.24 TIME_WAIT
