◆ AppLayerProtoDetectRegisterProtocol()

void AppLayerProtoDetectRegisterProtocol	(	AppProto	alproto,
		const char *	alproto_name
	)

Registers a protocol for protocol detection phase.

   This is the first function to be called after calling the
   setup function, AppLayerProtoDetectSetup(), before calling any other
   app layer functions, AppLayerParser or AppLayerProtoDetect, alike.
   With this function you are associating/registering a string
   that can be used by users to write rules, i.e.
   you register the http protocol for protocol detection using
   AppLayerProtoDetectRegisterProtocol(ctx, ALPROTO_HTTP1, "http"),
   following which you can write rules like -
   alert http any any -> any any (sid:1;)
   which basically matches on the HTTP protocol.

Parameters

alproto	The protocol.
alproto_str	The string to associate with the above "alproto". Please send a static string that won't be destroyed post making this call, since this function won't create a copy of the received argument.

Return values

0	On success; -1 On failure.

Parameters

f	flow to act on
dp	destination port to use in protocol detection. Set to 443 for start tls, set to the HTTP uri port for CONNECT and set to 0 to not use it.
expect_proto	expected protocol. AppLayer event will be set if detected protocol differs from this.
