Lisa Bock reviews and demonstrates two command line tools to work with packets, text2pcap which converts a hex dump to a capture file and capinfos which provides statistics about a capture file.
- [Instructor] Within Wireshark,…you'll see a number of files…that have to do with the basic functionality of Wireshark,…but then you see some other applications…that can be run independently.…Two applications that work well together…are Text2pcap and Capinfos.…Now, Text2pcap takes a hexdump…and converts it into a capture file.…Now, you might get a hexdump because not all applications…are capable of exporting the data into a pcap format,…so this is a handy little tool,…and then you can pull it into Wireshark for analysis.…
Now, you can also look at Capinfos.…Now, Capinfos again is a command line tool…that provides statistics about a capture file.…Now, there are a number of switches,…and once we get into the command line,…we'll take a look,…but this provides details about a single file.…I have created a little temporary directory in the C drive…and I've put in what's called DumpCaps.…And we'll open that up,…and as you can see, this is a hexdump.…Now, it doesn't make sense to anyone…because it's in hexadecimal.…
