.Dd January 12, 2011 .Dt SHMIF_DUMPBUS 1 .Os .Sh NAME .Nm shmif_dumpbus .Nd examine shmif bus contents .Sh SYNOPSIS .Nm .Op Fl h .Op Fl p Ar pcapfile .Ar busfile .Sh DESCRIPTION The .Nm utility examines the bus of an .Xr shmif 4 Ethernet interface. The most useful feature is converting the bus to the .Xr pcap 3 file format for later examination. .Nm itself is limited to displaying only very basic information about each frame.
p .Nm accepts the following flags: l -tag -width xxxpcapfilexxx t Fl h Print bus header only and skip contents. t Fl p Ar pcapfile Convert bus contents to the .Xr pcap 3 format and write the result to .Ar pcapfile . The file .Fl signifies stdout. .El .Sh EXAMPLES Feed the busfile contents to pcap: d -literal -offset indent $ shmif_dumpbus -p - busfile | tcpdump -r - .Ed .Sh SEE ALSO .Xr pcap 3 , .Xr shmif 4 , .Xr tcpdump 8 .Sh CAVEATS .Nm does not lock the busfile and is best used for post-mortem analysis of the bus traffic.
p The timestamp for each frame contains the sender's timestamp and may not be monotonically increasing with respect to the frame order in the dump.
