1.problem:

[root@fundation10 Desktop]# tcpdump dst port 9090tcpdump: WARNING: enp0s25: no IPv4 address assignedtcpdump: verbose output suppressed, use -v or -vv for full protocol decodelistening on enp0s25, link-type EN10MB (Ethernet), capture size 65535 bytes^C0 packets captured0 packets received by filter0 packets dropped by kernel

2.how to solve the problem
from online

1. 是有反应的，你可以另开终端，ping 91.189.89.144；你这里告警了eth0: no IPv4 address assigned，eth0网卡有IPv4地址吗？tcpdump -D可以列出所有的网卡信息，看你10.172.3.29是哪个网卡的IP，“tcpdump -i 网卡前数字或网卡名 host 10.172.3.29 and 91.189.89.144”试试；2. 上面解决了再说这个，你可以另开终端，ping 91.189.89.144，再捕获试试；3. host表示单个主机，也就是单个IP地址；4. host是单个主机，net是子网（多个IP地址）；详细的你可以搜一下tcpdump教程

我使用了第一种方法解决了问题：
步骤：
1.列出所有网卡信息

[root@fundation10 Desktop]# tcpdump -D1.enp0s252.br03.virbr04.bluetooth0 (Bluetooth adapter number 0)5.nflog (Linux netfilter log (NFLOG) interface)6.nfqueue (Linux netfilter queue (NFQUEUE) interface)7.usbmon1 (USB bus number 1)8.usbmon2 (USB bus number 2)9.wlp3s010.any (Pseudo-device that captures on all interfaces)11.lo

2.指定网卡查询，效果如下：

[root@fundation10 Desktop]# tcpdump -i 11 dst port 9090tcpdump: verbose output suppressed, use -v or -vv for full protocol decodelistening on lo, link-type EN10MB (Ethernet), capture size 65535 bytes18:42:00.637845 IP localhost.45522 > localhost.websm: Flags [S], seq 3537773743, win 43690, options [mss 65495,sackOK,TS val 63661 ecr 0,nop,wscale 7], length 018:42:00.637878 IP localhost.45522 > localhost.websm: Flags [.], ack 3839637389, win 342, options [nop,nop,TS val 63661 ecr 63661], length 018:42:42.054341 IP localhost.45522 > localhost.websm: Flags [P.], seq 0:6, ack 1, win 342, options [nop,nop,TS val 105078 ecr 63661], length 618:42:52.615637 IP localhost.45522 > localhost.websm: Flags [F.], seq 6, ack 1, win 342, options [nop,nop,TS val 115639 ecr 105078], length 018:42:52.615702 IP localhost.45522 > localhost.websm: Flags [.], ack 2, win 342, options [nop,nop,TS val 115639 ecr 115639], length 0^C5 packets captured10 packets received by filter0 packets dropped by kernel
