Nemesis v1.6

Nemesis the Destroyer

Changes

• Support for DHCP protocol crafting, defaults to DHCP Discover with option 53, 12, 60, 61, and 55
• Support for repeated send in many protocol injectors. Can be used to, e.g., flood networks with ARP requests or test DHCP.
• Incompatible command line option changes to IGMP protocol module

Fixes

• Fix #4: invalid IP header length in ICMP packets, by Samy Kamkar

Nemesis v1.5

Nemesis the Resurrection

Changes

• Merged Nemesis libnet1 port, from stale CVS branch
  • Fixed libnet1 porting regression in nemesis-proto_icmp.c
  • Finished port of nemesis-printout.c to libnet1
  • Finished port of nemesis_proto_ospf.c, new HELLO API. Added workaround for missing "Active Neighbor" in libnet1
  • Removed lots of unused local variables, remnants from port
  • Updated configure script to check for libnet1
  • Re-KNF:ed entire source tree in libnet1 port merge. New file in root of tree: .clang-format for auto-indenting (exprimental)
• Finished OSPF injector implementation, drop beta status
• Changed default values for RIP injector, use v2 and 224.0.0.9
• Minor license refactor to be auto-detected as 3-clause BSD
• Removed build number from version string
• Simplified usage/help texts for all injectors, more readable format
• Replaced hard-coded version number with PACKAGE_VERSION
• Changed README and ChangeLog to Markdown format, reorder the ChangeLog in reverse chronological order, latest first
• Added some examples (!) to the README, everybody likes examples :)
• Removed all generated autoconf/automake files from GIT. Use the ./autogen.sh script when building from GIT.
• Renamed configure.in --> configure.ac and clean up the build system a bit, for readability and simplicity
• Merged Debian .deb package build support, incl. modernize

Fixes

• Merged mailing list fix to allow IGMP group 0.0.0.0 when sending a general query. Thanks to Randy Robertson mailto:rmrobert@vmware.com
• Fixed long-standing OSPF non-functioning bug. Caused by static declaration of OSPF variables in header file
• Fixed needless byte-swapping in the following injectors, libnet1 does this for us already. Possible bug in earlier versions:
  • OSPF
  • RIP
  • ICMP

Nemesis v1.4

New and improved nemesis: nemesis-ethernet and nemesis-ip.

Changes

• Windows support (link-layer injection only)
• Useful man pages
• Single binary
• Improved cross-platform support via GNU autotools
• Easier to use
  • Nemesis will attempt to fill in as many details as possible in a packet, thus requiring fewer or even no command line switches
  • Each protocol builder attempts to build a proper packet by default
• Organized code base
  • The network header structures in libnet proved useful so nemesis now uses them where appropriate
  • Code is re-used wherever possible resulting in a much more concise code base
• Full payload functionality
  • Payloads can now contain NULLs within them and full-size packets are available on all supported platforms except Windows
• IP and TCP options support
  • All nemesis injectors (excluding ARP and Ethernet) now support IP options via -O <file>
  • All nemesis injectors using TCP as a transport protocol now support TCP options via -o <file>
• Improved IP and TCP functionality
  • Full IP fragmentation support via new -F command line semantics
  • ECN support in TCP with the addition of -fE (ECE) and -fC (CWR)
• Switched to GNU ChangeLog format
• Moved printout functions into nemesis-printout.c
• Moved file I/O functions to nemesis-fileio.c
• Incorporated strlcpy() and strlcat() into source tree
• Updated configure.in to use AC_REPLACE_FUNCS for locally included functions: strlcpy(), strlcat(), strspn(), inet_aton()
• Removed struct OptionsData and PayloadData in favor of FileData
• Changed builddatafromfile() to accept a FileData *
• removed acconfig.h and replaced with AH_TOP macro in configre.in
• updated aclocal.m4, missing, mkinstalldirs, configure, configure.in, config.guess, Makefile.in, man/Makefile.in and src/Makefile.in as part of autotools updates

Fixes

• Man page fixes from nnposter@users.sourceforge.net

• minor man page cleanup

• nemesis-proto_ip.c:

    -    ip_meta_packetlen = ip_packetlen - (link_offet + LIBNET_IP_H);
    +    ip_meta_packetlen = ip_packetlen - (link_offset + LIBNET_IP_H);
  

• added .cvsignore to CVS

• allow TCP packets to be sent without flags using -f-

• allow RIP routing domain value to be 0 with RIP2

• correct mistakes in specifying payload sizes for ICMP and RIP

• added src/memcmp.c to satisfy automake dependency

• debug fixes to configure.in
