I am developing a plugin for test purposes on our system, and I need to
extract the destination IP address of the packets so I know how to parse
the data on top of a TCP packet.
So is this a plugin dissector or a plugin tap?
If it's a dissector, then:
Is there an API or other method of
obtaining the IP address for comparison?
yes - your dissector will be passed a packet_info pointer, which we'll
call "pinfo", and:
pinfo->src is an "address" structure with the packet's source address;
pinfo->src is an "address" structure with the packet's destination address.
NOTE: it could be an IPv4 or IPv6 address. An "address" structure has a
member named "type" which could be AT_IPv4 or AT_IPv6 for the source or
destination address of an IP packet.
I should note that I�m
developing in a windows environment in case that makes any difference.
It doesn't - the APIs for getting and processing packet data are
platform-independent.
