B4J Question Packet Raw Data... read everything...

[Magma]

...Well i am trying to update/transfer/TRANSFORM some old Applications from Visual basic to B4J...

so... my need "today" is PacketX...

PacketX was a library that helps reading all the packets from ethernet... actually was a wrapper of WinPcap..

So the best fuction was that:

oPacketX_OnPacket(ByVal pPacket As PacketXLibCtl.IPktXPacket)

ppacket. had SourceIpAddress/Port/DestIP/DestPort...Data...MacAddress...DataSize..Protocol !!!

As you can see with this super WOW library you could read everything coming to your ethernet port !

So is there any nature way or something like packetx/winpcap for b4x... to read them all ?

ps: My old apps was a software router, and a little firewall...

Take a look at this, you will have to write a wrapper for this so it can be used in B4J

If i use jnetwork library ... for listening specific ports - is it possible to listen perhaps icmp port (1) ?


...and how...? using inputstream ? or something ?

 

[Erel]

Socket from jNetwork library will not give you such low level access.

 

[Magma]

i understand.... is there a future option to port / wrap something like npcap/winpcap ?

 

[Erel]

It might be wrapped in the future. This is quite a large library.
