Hi,

[Forwarded from ndb-j list] Hi;

I am going to develop a plug-in for Ethereal because I want to sniff the packets between NDB nodes and NDB-API. But I have many problems. The ports used for sending packets between nodes and api are dynamic ports and the packets in NDB-API are packet into an adaptive-send buffer that is flushed every 10ms or when it is full.

It is possible to set the port, otherwise I gather it'll be hard to use ethereal sniffing.

I need to know how are packed the signals into the buffer for recognizing its structure. I look for in the source code but i can not find anything. Could someone help me, please?

There is a signal format called Protocol6 which you'll find in the code, it's probably not the simplest thing in the world to track this protocol, there is a lot of detail to it. But it is certainly possible.

Rgrds Mikael

Best regards;

Fernando
