HEAD is the head of the CVS tree where we do check in all the fancy and new

hi,
i am not 100% sure if i do understand your question;
if its regarding printing a hexdump of an arbitrary
(including ICMP) then you may want to try tcpdump
with the -X flag;
see the tcpdump man page for details;

karsten,
i have checked in support for DLT_PPP_WITH_DIRECTION in
tcpdump and the PPP printer - the PPP printer shows now
the direction (hidden under the -e flag)

karsten,
i have checked in support for the new DLT_PPP_WITH_DIRECTION (166) and
LINKTYPE_PPP_WITH_DIRECTION (166)
also i tweaked libpcap to treat it like PPP plus support of
the inbound/outbound tokens;
see below testresults ...

karsten,
could you elaborate a bit more on "it creates binary incompatible filters";
in my testbed the linux machine creates 100% correct BPF filters;
e.g.
--->encaps is LINUX_SLL
# tcpdump -i ppp0 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
