Kuznetsov's modified "libpcap" *as long as you have the ss990915 or

number to see that it's Not Standard Libpcap. (Even more unfortunately,
Red Hat appears to have picked up *that* patch for Red Hat 6.1; I've
filed bug 6773 with Bugzilla on their site - hopefully, if I'm not

Rearranged the order in which wiretap tries trace files, to keep the
ASCII-readers (ascend and toshiba) at the end, and put the binary-readers
(everything else) at the front of the list. If a telnet session of
and ascend trace or toshiba trace were captured near the beginning of
another trace, wiretap might think the trace was ascend or toshiba if it
tried that module first.

not, so it's OK to use "zlib" to read capture files, as it handles
uncompressed files correctly.
When *writing* capture files, however, we can't detect automatically
whether the user wanted to write the file out as a compressed file or
not, so we should *NOT* use "zlib" until we add a flag to the API
specifying whether to write the file out as a compressed file or not.
Furthermore, the code in Ethereal that implements the "-S" flag depends
on being able to get the "FILE *" for a capture file being written, so
that it can "fflush()" it.

"FDDI with the MAC addresses bit-swapped"; whether the MAC addresses are
bit-swapped is a property of the machine on which the capture was taken,
not of the machine on which the capture is being read - right now, none
of the capture file formats we read indicate whether FDDI MAC addresses
are bit-swapped, but this does let us treat non-"libpcap" captures as
being bit-swapped or not bit-swapped independent of the machine on which
they're being read (and of the machine on which they were captured, but
I have the impression they're bit-swapped on most platforms), and allows
us to, if, as, and when we implement packet capture in Wiretap, mark
packets in a capture file written in Wiretap-native format based on the
machine on which they are captured (assuming the rule "Ultrix, Alpha,
and BSD/OS are the only platforms that don't bit-swap", or some other
compile-time rule, gets the right answer, or that some platform has
drivers that can tell us whether the addresses are bit-swapped).
(NOTE: if, for any of the capture file formats used only on one
platform, FDDI MAC addresses aren't bit-swapped, the code to read that
capture file format should be fixed to flag them as not bit-swapped.)
Use the encapsulation type to decide whether to bit-swap addresses in
"dissect_fddi()".

3) little-endian AF_ value (BSD on little-endian platforms);
4) two octets of 0 followed by an Ethernet type (Linux, at least

it's a Linux-style header; dissect it ourselves only if it's an AF_

Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.

message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening

Include loopback interfaces in the list of interfaces offered by the

IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).

if you're doing builds from a tree freshly checked out from CVS, "XXX"

That requires that, in the packet-reading loop, we pass to the callback
routine the offset in the file of a packet's data, because we can no
longer compute that offset by subtracting the size of the captured
packet data from the offset in the file after the data was read -
"snoop" may stick padding in after the packet data to align packet
headers on 4-byte boundaries.
Doing that required that we arrange that we do that for "libpcap"
capture files as well; the cleanest way to do that was to write our own
code for reading "libpcap" capture files, rather than using the
"libpcap" code to do it.
