Description

I used the “-w” parameter of rvtrace to capture and write network packets to a file using the correct network interface.  When I read the recorded packets using the “-i” parameter, the resulting statistical snapshot was empty and appeared as if no data was captured.  Why is this happening?

 

Issue/Introduction

I used the “-w” parameter of rvtrace to capture and write network packets to a file using the correct network interface.When I read the recorded packets using the “-i” parameter, the resulting statistical snapshot was empty and appeared as if no data was captured.Why is this happening?

Environment

all

Resolution

rvtrace supports only Ethernet interfaces.  So, it is possible that the data you have captured is from a non-Ethernet interface (such as Token Ring, FDDI, ATM).  If this is the case, you could try running

                                        rvtrace –filter “” -r &ltcapture_file>

when reading the recorded packets, and this should take *all* packets into consideration.

(NOTE: using -filter "" as an expression is not documented.)
