NAME

       pydhcp - a dhcp command line tool

USAGE

       pydhcp --input <TYPE;OPTIONS;NAME> --output <TYPE;OPTIONS;NAME>

DESCRIPTION

       pydhcp  is  a  command  line  tool to read or write dhcp packet on network, and translate from raw data to human readable informations (and
       vice-et-versa). pydhcp is a part of the pydhcplib python library.

Input and Output field description
       pydhcp takes an input and an output argument. Input and output are described in the same way. For example :

       pydhcp --input 'device;binary|up;eth0:68' --output 'file;readable;myfile.txt' -c 1

<TYPE> field
       There is 5 types for the <TYPE> field. Only one type at once can be used : device, address, file, stdin and stdout. device tells pydhcp	to
       write  or  listen  directly  on the network interface and port. address is to write or listen on a specific Internet Address and port (like
       192.168.1.1:67 ). file read or write data from or to a file. stdin read data from stdin, stdout write data on stdout.

<OPTIONS> field
       You can use multiple options in the option field by separate them with a pipe |. There is 4 options for this field : readable,  binary,	up
       and  noup. readable id to read or write data in a human readable language : a packet definition language. This language is described later.
       Binary form stand for reading or writing packets in the same binary form they are on the network : an UDP packet. readable and  binary  are
       mutually exclusive.  Option up tells pydhcp to set the network interface up if not. noup tells not to set up the interface. up and noup are
       only useful in combination with the device type. Default is noup.

<NAME> field
       Describe the name of the device (eth0:67,wlan0:client) , the address (192.168.1.1), or the filename (foo.txt). You can use a port number or
       the keywords client and server for standard dhcp port.

Other command line options of pydhcp
       Option -c : Number of packet to read or write. 0 for unlimited number of packet. Default is 0.

Known limitations
       - Only one dhcp packet per file, then count is set to 1 for file I/O - No readable transfert on network (address or device). Binary only.

       -c|--count
	      Number of packets to process.

EXAMPLES

       Read a client packet on any address and write it on a human readable file :

       pydhcp -i "address;binary;0.0.0.0:67" -o "file;readable;myfile.bin"

       Read a binary dhcp packet from a file and print it on stdout in a human readable form :

       pydhcp -i "file;binary;myfile.bin" -o "stdout;readable;"
