Summary: Parallel Internet measurement utility
Scamper is a program that is able to conduct Internet measurement
tasks to large numbers of IPv4 and IPv6 addresses, in parallel, to
fill a specified packets-per-second rate. Currently, it supports the
well-known ping and traceroute techniques, as well as MDA traceroute,
alias resolution, some parts of tbit, sting, and neighbour discovery.

Scamper can do ICMP-based Path MTU discovery. scamper starts with the
outgoing interface's MTU and discovers the location of Path MTU
bottlenecks. scamper performs a PMTUD search when an ICMP
fragmentation required message is not returned to establish the PMTU
to the next point in the network, followed by a TTL limited search to
infer where the failure appears to occur.

  - update to version 20181219:
    * scamper:
    * json output format for tracelb (MDA traceroute)
    * print an error message if an output file cannot be opened
    * document (in warts.5) the offset variable in a warts traceroute record,
      and scamper_trace_dtree_t
    * use autoconf to check if X509_VERIFY_PARAM_set1_host is available,
      rather than OpenSSL #defines that are not used consistently among
      OpenSSL-like libraries.
    * libscamperfile:
    * don't crash on a zero length file, or other conditions where sf->type
    * fix example in manual page
    * dump 3: when merging routers in a transitive closure, remove the
      obsolete router from the dump list.
    * if an address is repeated in the input file then complain
    * sc_bdrmap:
    * document -C csum in sc_bdrmap.1
    * allow duplicate prefixes in the IXP file
    * add initial support for UDP paris traceroute, as an alternative
      to the ICMP paris traceroute bdrmap uses by default.
    * document updates in sc_bdrmap.1
    * sc_ttlexp:
    * add -O noreserved
    * bugfix reading from stdin, file handling
    * document updates in sc_ttlexp.1
    * sc_uptime:
    * add an optional -I interval parameter which controls how frequently
      we want an address to be probed.  add logic to exit early if we are
      probing on with -I and there is a list of low-priority probing
      that is not empty, so that sc_uptime can meet the probe interval.
    * add the ability to expire addresses out of the database after they
      have not been seen in traceroute for a while, and they do not
      respond with an incrementing IPID value, with optional -E expiry
    * loading addresses into the state database is now a separate step (-a)
    * add a -c option to create and initialise a database file
    * add do-not-probe support
    * replace import code that used a row for each sample with a blob that
      stores multiple samples per blob.
    * report some measure of progress on import
    * build monotonic sequences which allow patterns in responses to be
      more easily identified, so that reboots are not falsely inferred
      in the cases of multiple counters, 16 bit counters, and routers
      that start each sequence after a PTB with a new IPID.
    * add an -O verbose to dump IPID sequences
    * document updates in sc_uptime.1
* Sun May 06 2018
  - update to version 20180504:
    * scamper:
    * increase the size of a buffer in scamper's traceroute json
      creation to reduce chance of truncation.
    * print the number of probes sent by traceroute in the json
    * enforce a minimum firsthop value of 1 when reading a warts
      traceroute object.
    * sc_bdrmap:
    * choose a static ICMP checksum value when using Paris traceroute
      to reduce churn in observed topology in bdrmap output.
    * add ability to pass list of ASes to -d traces to see
      traceroutes towards specific ASes, useful for understanding
      bdrmap inferences.
* Thu Mar 08 2018
  - update to version 20180309:
    * sc_*:
    * For the utilities (sc_*) that read input files, do not allocate
      memory to hold the entire input file in memory before parsing
      the file.  This improvement affects sc_ally, sc_attach,
      sc_bdrmap, sc_filterpolicy, sc_radargun, sc_speedtrap,
      sc_tbitblind, sc_tbitpmtud, sc_uptime, sc_warts2text.
    * sc_tbitpmtud:
    * add scamper driver from IMC2010 paper to collect data on webserver
      responsiveness to ICMP packet too big messages, and perform
      rudimentary analysis of collected data.
    * sc_ttlexp:
    * new utility to dump source addresses from ICMP TTL expired
      messages in warts files.
    * sc_wartsfix:
    * add a manual page
    * sc_warts2csv:
    * add a manual page
* Mon Dec 04 2017
  - remove new-openssl.patch, included upstream
  - update to version 20171204:
    - scamper:
    * add a blind-fin tbit test, which tests receiver behavior to TCP FIN
      packets which could have come from an off-path attacker.
    - sc_radargun:
    * add -d 2 option, which dumps interface IP-ID behavior classifications.
* Thu Nov 30 2017
  - add patch new-openssl.patch to compile with new openssl versions
* Thu Aug 24 2017
  - update to version 20170822
    * replace recursive versions of some functions with iterative versions.
    * add cycle-start and cycle-stop json record implementations.
    * fix traceroute json record: the hop transmit time value it reported
      was junk.
    * add support for sending json over the control socket.  use
      "attach format json" to get this mode; "attach" by itself still
      returns uuencoded warts.  Initial patch supplied by Young Hyun.
    * fix possible memory leaks detected with static analysis.
    * quality assurance on research paper cites in manual pages.
    * spelling errors noticed by Iain R. Learmonth.
    * add feature to dump inferred aliases from the collected data.
    * add threaded implementation of pairwise comparison to form candidate
      alias sets, if pthreads are detected at compilation time and
    - -disable-threads configure option is not supplied.
    * new scamper driver to infer IPv6 device reboot windows if the device
      returns an incrementing identifier field in the IPv6 fragmentation
      header.  the driver is not built by default, as it expects sqlite3.
      use --with-sc_uptime configure option to build.
* Thu Jun 22 2017
  - update to 20161204a
    * More fixes to libscamperfile caught with fuzz testing.  corrupt
    warts files provided by Greg Ward of Dyn
    * if targets or commands are specified in a file, and that file
    ends after all probing of commands in that file has completed,
    finish the source, allowing scamper to exit.  this scenario is
    most likely when stdin is the input file.  Reported by Alex
    Colvin of Dyn
    * use select/poll/epoll/kqueue to look for read events on stdin files
    * malloc enough memory for a prefix6_t in the prefixtree code.  reported
    by Sebastian Wagner via gcc7.  only sc_bdrmap uses that code
    * increase size of string buffers for some ping and trace fields for text
    output to silence gcc7 warning.
    * allow source IP address to be null when outputting a trace with json
    * update sc_tbitblind.1 man page to show correct use of scamper's IPFW
    firewall support, which changed in the 20161204 release
    * fix unlikely unaligned access when computing checksums with IPv6
* Wed Jun 21 2017
  - update to 20161204
    * add remote control socket support to scamper.  scamper can be
    configured to connect to a remote controller at run time to
    allow remote systems to control a scamper instance.  the
    remote controller is handled by the sc_remoted utility, and
    is documented in the sc_remoted manual page (see below).
    * fixes to libscamperfile caught with fuzz testing.  corrupt
    warts data files provided by Greg Ward of Dyn.
    * add a PATRICIA trie implementation based off Sedgewick's
    Algorithms in C++ book.  this improves the performance
    of scamper compared to holding addresses in splaytrees.
    * improve speed of warts(5) code.
    * improve speed of scamper_writebuf by allocating pagesize blocks
    at a time.
    * begin to document ping warts records in warts(5).
    * fix debug printf implementation so that all features will
    be built in as long as --without-debugfile is not used.
    backported to 20141211g.
    * silence compiler warnings from Microsoft Visual Studio.
    backported to 20141211g.
    * sc_prefixscan:
    * add a utility, sc_prefixscan, that provides a convenient
      interface to scamper's prefixscan alias resolution method.
    * sc_radargun:
    * add a utility, sc_radargun, that provides a convenient
      interface to scamper's radargun implementation.
    * sc_remoted:
    * add a utility, sc_remoted, that provides an interface to a
      collection of remote scamper instances.
    * sc_ally:
    * use writebufs so sc_ally is event driven and will not block.
    * add code to probe candidate sets in pairs, with transitive
      closure to save probes.
    * allow inter-probe gaps of less than 1 second.
    * sc_attach:
    * add support for remote control sockets.
    * add an option to randomise the order tasks are run.
    * sc_speedtrap:
    * stricter default test for inferring if two IP addresses may
      share a single shared counter.
      backported to 20141211g.
    * code cleanup.
    * sc_warts2json
    * add support for printing ICMP extensions included in traceroute
      responses, prompted by Quirin Scheitle
* Sat Oct 08 2016
