Things to do:
|
|
=============
|
|
|
|
*) Protocol dispatchers, allowing run-time setting of protocol "chaining"
|
|
(i.e., UDP port X calls dissector Y)
|
|
|
|
*) Work on packet capturing in wiretap - or just make it a wrapper
|
|
around libpcap/WinPcap, hiding some of the stuff Ethereal and
|
|
Tethereal currently have to do independently
|
|
|
|
*) Either as part of the previous item, or as a capture-filter
|
|
translator that generates "libpcap"-style capture filter expressions,
|
|
provide a capture filter syntax similar to the display filter syntax.
|
|
(The syntax differences get in the way of users; the fact that you have
|
|
to construct some filters by hand, e.g. looking only for initial SYN
|
|
packets for TCP connections by doing bit-testing of the flags in a TCP
|
|
header has been a pain for some users; and people have asked for
|
|
capabilities that aren't conveniently available, or aren't available at
|
|
all, in "libpcap"-style capture filters:
|
|
|
|
the ability to filter on characteristics of IPX packets;
|
|
|
|
the ability to select, for example, TCP packets with port
|
|
numbers *greater than* a particular value, which in "libpcap"
|
|
filters you have to do by explicitly testing subfields of the
|
|
TCP header rather than doing "tcp.port > 1000";
|
|
|
|
etc.)
|
|
|
|
*) I just discovered that sshd sets the SSH_CLIENT variable to source IP,
|
|
sort port, and destination port. That coupled with a destination IP
|
|
would give us enough information to carry out remote protocol capturing,
|
|
tcpdump over ssh:
|
|
|
|
ssh remotehost tcpdump -s 2000 -w - filter,
|
|
|
|
where "filter" filters out our own ssh packets (using the infromation
|
|
from $SSH_CLIENT). Any takers?
|
|
|
|
*) Of course, packet defragmentation. We currently reassemble:
|
|
|
|
IP fragments
|
|
IPv6 fragments
|
|
OSI CLNP segments
|
|
ONC RPC-over-TCP and DCE RPC fragments
|
|
802.11 fragments
|
|
X.25 packets with M set
|
|
ATP fragments
|
|
EAP/TLS fragments
|
|
Fibre Channel fragments
|
|
Netware NDPS fragments
|
|
NBF fragments
|
|
Fragmented SNA BIUs
|
|
TDS (Sybase/Microsoft SQL Server) fragments
|
|
WTP fragments.
|
|
|
|
and currently support, for many protocols running atop TCP and the
|
|
SMB pipe protocol, reassembling the data stream and breaking the
|
|
resulting stream into higher-level packets. We want to support that
|
|
for more TCP-based protocols; we might also want to reassemble:
|
|
|
|
NBDS
|
|
PPP Multilink
|
|
|
|
and possibly other protocols.
|
|
|
|
*) I'd like to someday re-write the display filter routines to have a more
|
|
powerful syntax.
|
|
|
|
*) More on-line help, and neato things with the protocol tree and
|
|
right-clicks.
|
|
|
|
*) A GtkClist replacement, with dynamic columns, allowing columns to be
|
|
added, removed, or moved without having to exit and restart Ethereal.
|
|
(guy)
|
|
|
|
*) A GUI capture/display filter creator (we have stuff to add fields to
|
|
display filters, but perhaps something such as what Network Monitor has,
|
|
to add AND/OR/NOT operators, would be useful)
|
|
|
|
*) Run-time configuration of tunnelling protocols -- display tunnelled
|
|
protocol as data or as a full-fledged protocol (which subtree do we put
|
|
it under?)
|
|
|
|
*) Run-time configuration of data shown in capture statistics window.
|
|
|
|
*) A GtkWidget for authors in the About box. We've got a lot of authors!
|
|
We've currently banished the list of authors to the AUTHORS file and the
|
|
man page, which may be the right solution here.
|
|
|
|
*) Finish moving GTK-dependent code into gtk/ subdirectory.
|
|
|
|
*) Provide alternative user interfaces, e.g. other toolkits (Qt/KDE,
|
|
full GNOME, native Windows, native Aqua, etc.) and text-mode "curses".
|
|
|
|
*) Kerberos version 4 dissector - standard krb4 - from tcpdump (nneul);
|
|
we have krb5, but not krb4
|
|
|
|
*) Display filters: add regexes to strings and byte ranges
