Parallel Internet measurement utility

https://www.caida.org/tools/measurement/scamper/

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 20170822
  scamper:
  * 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.
  
  sc_ally:
  * add feature to dump inferred aliases from the collected data.
  
  sc_speedtrap:
  * 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.
  
  sc_uptime:
  * 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.
