Linux系统中,tcpdump监听网卡 eth0,对方主机IP为10.1.1.180,tcp端口为80的数据,相应命令为
A: tcpdump -h eth0 -nn ‘tcp and host 10.1.1.180:80’
B: tcpdump -i eth0 -nn ‘tcp and host 10.1.1.180:80’
C: tcpdump -h eth0 -nn ‘tcp and port 80 and host 10.1.1.180’
D: tcpdump -i eth0 -nn ‘tcp and port 80 and host 10.1.1.180’
A: tcpdump -h eth0 -nn ‘tcp and host 10.1.1.180:80’
B: tcpdump -i eth0 -nn ‘tcp and host 10.1.1.180:80’
C: tcpdump -h eth0 -nn ‘tcp and port 80 and host 10.1.1.180’
D: tcpdump -i eth0 -nn ‘tcp and port 80 and host 10.1.1.180’
举一反三
- tcpdump命令指定监视指定网络接口的数据包() A: -i B: -nn C: -e D: -c
- Consider a TCP connection between Host A and Host B. Suppose that the TCP segment traveling from Host A to Host B have source port number x and destination port number y. What are the source and destination port numbers for the segments traveling from Host B to Host A?
- 42为网卡eth0设置临时IP地址的命令是: A: ipconfig eth0 B: ifconfig eth0 C: ipconfig D: ifconfig
- 关于ifconfig命令,下面描述正确的是 A: 直接键入ifconfig命令不带参数,可以查看系统中所有的网络接口 B: 默认情况下,每台主机上都有一个lo接口 C: 可以用 ifconfig eth0 on 命令来开启eth0接口 D: 可以用 ifconfig eth mtu 2000 将eth0接口的mtu值设置为2000
- 下列关于网卡操作不正确的是() A: 激活网卡eth0的命令为ifupeth0。 B: 激活网卡eth0的命令为ifdowneth0。 C: 关闭网卡eth0的命令为ifupeth0。 D: 关闭网卡eth0的命令为ifdowneth0。
