| 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.

- remove SIOCGSTAMP.patch
- update to version 20190916:
* scamper
* add a host implementation for looking up DNS records. it uses
the first nameserver it finds in /etc/resolv.conf by default.
* add an -O ptr option to tracelb.
* bugfix json output for tracelb.
* integrate patricia trie implementation into scamper hotspot
* use HAVE_SYSCTL macro to solve a compile issue on android
* include <linux/sockios.h> to get SIOCGSTAMP in Linux kernel > 5.2
* add -A option to ping code to set the ack number to use in tcp
probes (or sequence number in SYN packets). do not randomly
generate sequence and ack values for each TCP ping.
* rework options handling to allow for long long values.
* set the window size in TCP probes to 65535, instead of advertising a
zero receive window.
* update configure scripts around the use of --with-privsep-dir-owner
* sc_ally:
* when outputting alias sets, conduct a canonical sort to allow for
easy diffs
* update man page because sc_ally can take more than two addresses per
line
* sc_erosprober:
* new driver to periodically probe addresses and rotate output files.
* sc_hoiho:
* new utility for holistic orthography of Internet hostname
observations. this utility is only built if --with-sc_hoiho is
passed to configure. sc_hoiho requires pcre or pcre2, which can be
controlled by passing --with-pcre or --with-pcre2 to configure.
* sc_uptime:
* add a last_tx column to state_dsts to allow for simple monitoring of
when each destination address was last probed.
* various drivers:
* handle scamper disconnections gracefully in sc_ally,
sc_filterpolicy, sc_prefixscan, sc_radargun, sc_speedtrap,
sc_tbitblind, sc_tbitpmtud, and sc_uptime
* Tue Aug 20 2019 Sebastian Wagner <sebix+novell.com@sebix.at>
- add SIOCGSTAMP.patch for recent changes in socket.h/socketios.h
* Sat Dec 22 2018 Sebastian Wagner <sebix+novell.com@sebix.at>
- 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
is SCAMPER_FILE_NONE
sc_ally:
* 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
parameter.
* 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 sebix+novell.com@sebix.at
- 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
output.
* 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 sebix+novell.com@sebix.at

sc_bdrmap, sc_filterpolicy, sc_radargun, sc_speedtrap,
sc_tbitblind, sc_tbitpmtud, sc_uptime, sc_warts2text.
* sc_tbitpmtud:

responsiveness to ICMP packet too big messages, and perform
rudimentary analysis of collected data.

* new utility to dump source addresses from ICMP TTL expired
messages in warts files.
* sc_wartsfix:
* add a manual page
* sc_warts2csv:
