A PCAP (Packet Capture) file extension is a commonly used file type for packet sniffers to capture and store data packets from networks. This type of file format is used for capturing network traffic between computers, servers, routers, or any other device on the network. Packet capture technology can collect all kinds of data including networks, websites, or applications. PCAP files typically save data in a binary format for easier storage and processing.
Technical Details
PCAP files are usually saved in the .pcap file extension which is the standard format for packet sniffer tools like Wireshark and NetworkMiner. It's also used in the TCPDUMP tool in .cap, .dmp, and .pcapng file formats. There are other less known formats like Microsoft Network Monitor which use the .cap extension. Furthermore, network intrusion detection systems may use other formats like .bsf, iptrace, or .snoop.
PCAP files are useful for network administrators when troubleshooting network problems and can be used to monitor network activity by network security experts. Distributed intrusion detection systems examine multiple network nodes at the same time as the data is collected and save it in a PCAP file. In addition, PCAP can be used in digital forensics cases for capturing malicious activity for further investigation.
Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PCAP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PCAP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PCAP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PCAP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PCAP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PCAP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PCAP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PCAP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PCAP file) will be extended to the maximum.
It is also good to check
- if the .PCAP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
