To run the program do the following from terminal: $ make $ ./hostman

This contains the source code of a simple TCP/IP packet analyzer. Its properties are:

1. Will work for LINUX systems (due to using console color in followPacketStream.c. Removing console color will make it work in windows)
2. GCC compiler works fine. MinGW will casue problem as the function fmemopen(), used in miscFunctions.c is not supported by MinGW
3. It does not capture packets. It only analyzes packets from a captured PCAP file
4. Command line driven program
5. Source code contains 12 files (8 .c files, 4 .h files) included with Makefile. See Source file explanation below to see the details of what each of them files does
6. Has options to view packet file data in several formats.

Compile the file using the provided make.

1. main.c: Checks for valid pcap file and valid cmd argument. If both are valid function in another src file is called
2. printUsage.c: Prints the usage (which commands invoke which functions)
3. miscFunctions.c: Contains miscellaneous functions that are required by other source files
4. packetBasicInfo.c: Prints source ip, destination ip, protocol, and size of each packet
5. packetDetails.c: Prints the details of each packets (all info of all the fields, including payload)
6. packetDump.c: Prints the hexdump of the packets along with their corresponding printable ASCII characters
7. packetSearch.c: Can search the PCAP file for packets by their IP or a string in their payload
8. followStream.c: Prints the conversation between two particular hosts in two different colors
