GLBP is a Cisco proprietary first-hop redundancy protocol similar to HSRP and VRRP, but with additional load balancing capabilities.
|
| |
|
| |
|
|
|
|
| |
IPP is identified *only* as HTTP subprotocol, so it can't be over UDP
(HTTP is only over TCP...)

Remove the specific dissector and use the Blizzard's generic one.
For the time being, keep `NDPI_PROTOCOL_WORLDOFWARCRAFT`

These flows are already classified as TLS.RDP.
This change also fix a memory leak
```
Direct leak of 62 byte(s) in 1 object(s) allocated from:

Add a new internal function `internal_giveup()`
|
| |
| |
| |
| |
| |
| |
| |
| | |
This function is always called once for every flow, as last code
processing the flow itself.
As a first usage example, check here if the flow is unidirectional
(instead of checking it at every packets)

This way, the `ndpiReader` output doesn't change if we change the
internal logic about the order we set/check the various flow risks.
Note that the flow risk *list* is already printed by `ndpiReader`
in order.

We calculate HTTP entropy according to "Content-type:" header, see
`ndpi_validate_http_content()` on HTTP code

Let's see if we are able to tell audio from video calls only looking at
RTP Payload Type field...

The Train Real Time Data Protocol (TRDP) is a UDP/TCP-based communication protocol designed for IP networks in trains, enabling data exchange between devices such as door controls and air conditioning systems. It is standardized by the IEC under IEC 61375-2-3 and is not related to the Remote Desktop Protocol (RDP).

ISO/IEC 14908-4 defines how to tunnel Control Network Protocol (CNP) over IP networks. It encapsulates protocols like EIA-709, EIA-600, and CNP, making it a versatile solution for building automation and control systems.

Add printing of fpc_dns statistics and add a general cconfiguration option.
Rework the code to be more generic and ready to handle other logics.

Let's start with some basic helpers and with FPC based on flow addresses.

Since 070a0908b we are able to detect P2P calls directly from the packet
content, without any correlation among flows

There is some overlap between RTP and Raknet detection: give precedence
to RTP logic.
Consequences:
* Raknet might require a little bit more packets for some flows (not a
big issue)
* some very small (1-2 pkts) Raknet flows are not classified (not sure
what do do about that..)
