3.先选中用来抓包的网卡,再在Capture filter for selected interfaces文本框内输入待用的抓包过滤器表达式(可按第1章所述来判断哪块网卡为活跃网卡[在用网卡])。在该输入栏中输入的抓包过滤器表达式会在相应网卡的Capture Filter栏下现身,如图3.3所示。图3.3显示的抓包过滤器tcp port http会让Wireshark只抓目的端口...
Each line of this file consists of an IPv4 address, a subnet mask length separated only by a / and a name separated by whitespace. While the address must be a full IPv4 address, any values beyond the mask length are subsequently ignored. An example is: # Comments must be prepended by ...
Classless InterDomain Routing (CIDR) notation can be used to test if an IPv4 address is in a certain subnet. For example, this display filter will find all packets in the 129.111 Class-B network: 当使用IPv4子网划分的时候,CIDR表示法也可以使用。例如:以下的过滤器可以找到所有129.111 B类网络地址...

这实际上是由另一组名为网络掩码(netmask, network mask)的地址信息所决定的,有时它也会被称为子网掩码(subnet mask)。 网络掩码用来标识IP地址中究竟哪一部分属于网络地址而哪一部分属于主机地址。网络掩码也是32位长,并且被设为1的每一位都标识着IP地址的对应部分是属于网络地址的,而剩下设为0的部分则标识...
filter to search for a sequence of characters, expressed as a string (quoted or unquoted), or bytes, expressed as a byte array, or for a single character, expressed as a C-style character constant. For example, to search for a given HTTP URL in a capture, the following filter can be...
Classless Inter-Domain Routing (CIDR) notation can be used to test if an IPv4 address is in a certain subnet. For example, this display filter will find all packets in the 129.111 network: ip.addr == 129.111.0.0/16 Remember, the number after the slash represents the number of bits used...

Makes it so they can run a packet capture on their machine and send to the network team for analysis. Lowcost Likelihood to Recommend Wireshark is a great tool to use after general network troubleshooting has taken place; checking subnet mask, default gateway, route table, etc. It can help...
