One more doubt. Please see the picture attached with the mail. Why is one byte left out without telling what it is??
Its after the end of One Tower and before the starting of another tower...

Thanks and Regards

Thank you Christian. Yup I got that.

I have one more query. How do we read the protocol towers?? I know that there are 5 columns and in 4 and 5, we have the port no. and IP address. But suppose as per our previously attached PCAP file, when we have more than one Towers, then what do the fields "Tower Array:", "Max Count", "Offset", "Actual Count" signify and then they are also there for each subtower. How to interpret it?? I couldn't find details about that in the DOC. Could anyone help for this.


Thanks and Regards

Hi Rahul,
 
 
there are two tower pointers with port# and IP addr!
You can see the payload on the tcp level (for frame 1610 -- payload =240 byte (see attached image as well))!

Christian

Betreff: [Wireshark-users] How is this DCERPC packet content interpreted?

Hi All,

I have attached an image file and a pcap file with the packets captured. You can see the packets by applying the filter "dcerpc" and see for packet no. 1610. I am unable to get how to see the payload of MSRPC and get the port_no and IP_Address exchanged in that packet. I need to write a code which will work for all DCERPC packets. Do help me in understanding the basic protocol format of DCERPC.

Thanks and Regards
Rahul Sharma
