Related: Wireshark User Interface (GUI) Overview Filtering Specific IP in Wireshark It’s also possible to filter out packets to and from IPs and subnets.īeyond that, you can use IP filters as both capture filters (only capture packets based on the filter) and display filters (filter the display of captured packets). We can filter to show only packets to a specific destination IP, from a specific source IP, and even to and from an entire subnet. With Wireshark we can filter by IP in several ways. One of the most common, and important, filters to use and know is the IP address filter. This amounts to a lot of data that would be impractical to sort through without a filter.įortunately, filters are part of the core functionality of Wireshark and the filter options are numerous. Unless you’re using a capture filter, Wireshark captures all traffic on the interface you selected when you opened the application. In this traffic capture, you can see traffic from different protocols, both traffic from the Spanning-Tree Protocol of the network, as well as TCP traffic and TLSv1.2 traffic from different applications that we have open.The ability to filter capture data in Wireshark is important. With these recommendations, we are sure that the traffic capture you make will be a success.
Today we have many protocols with encrypted data, with the appropriate private key, Wireshark is able to decrypt the traffic of different protocols such as IPsec, ISAKMP, Kerberos, SNMPv3, SSL / TLS, WEP, and WPA / WPA2.ĭouble-clicking will automatically start capturing all network traffic, both inbound and outbound. Of course, it is capable of reading data from different network technologies such as Ethernet, IEEE 802.11, PPP / HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI and others. Another important aspect is that the captured capture can be compressed with GZIP on the fly, and of course, decompress it on the fly also in case we are reading the capture. Wireshark is capable of reading and writing in different capture formats, such as tcpdump (libpcap), pcap ng, and many other extensions, to perfectly adapt to different programs for further analysis. A fundamental characteristic of any packet analyzer is the filters, so that it only shows us what we want it to show us, and no more information that would generate extra work for us.
Wireshark allows to see all the traffic captured via GUI with the program itself, however, we can also see all the information captured with the TShark program, a tool that works through the console and will allow us to read everything through the CLI command line, to see everything via SSH, for example.
