- scamper:
* gracefully handle situations where there is no
/etc/resolv.conf, or no nameserver lines in an /etc/resolv.conf
but a measurement or scamper-internal task wants to resolve a
name
* tidy up buggy prinf-like statements in scamper and some drivers.
- warts/json:
* in JSON output for ping, print the TCP/UDP src/dst ports or
ICMP id/seq used in individual probe packets,
* fix regression in libscamperfile so that it can read old warts
files.
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=41
* add an option (-O cafile=/path/to/file) to load CA certificates
from a specific file when starting scamper for validating a
remote controller's certificate (this was released in 20211212a)
* add options
-O client-certfile=/path/to/certfile and
-O client-privfile=/path/to/privfile

with a remote controller
* fix bugs that prevent scamper from reconnecting to a remote
controller
* fix -d debugfile when scamper is built with privilege separation
* fix bug when writing neighbordisc measurements to warts file that
prevents a neighbordisc measurement from being read
* fix bug when reading some tracelb measurements with unresponsive hops
from a warts file

- sc_remoted:
* add -C option to specify a CA PEM file to verify client certificates
presented by scamper instances.
* add -O skipnameverification option to tell sc_remoted to verify
scamper presents a certificate signed by the CA, but do not do
name verification

- No changelog available.
- update to version 20211212:
- scamper:
* in hostname code, handle nameserver lines with comments in them
- sc_remoted:
* fix logic to handle TLSv1.3 handshakes
- sc_hoiho:

scamper:
* in trace, allow probes to multiple consecutive hops to be
outstanding in the network without having to stop and wait,
using the -N parameter documented in scamper's man page.
* in trace, do optional PTR lookups using the option documented
in scamper's man page. output these hostnames into warts and
json outputs.
* bump libscamperfile version for the above changes.
* document that scamper's control socket can be told to return
JSON through an option now documented in scamper's man page.
* improvements to reading warts files via fuzzing.
* other man page tidy ups.
sc_erosprober:
* add the ability to adjust the probe list at run time through a
unix domain socket, documented in the sc_erosprober man page.
sc_hoiho:
* add the ability to learn regular expressions that extract
geographic hints from router hostnames, documented in the
sc_hoiho man page

- scamper:
- update remote control protocol to support session resumption
if the underlying TCP connection is interrupted.
- if remote controller is specified with a domain name, use TLS.
- fix -p pidfile when starting scamper as a daemon
- expire entries in the ARP cache periodically
- add -r support to ping and tracelb, and record router addresses
in warts output.
- autoconf work to build on linux without sys/socketvar.h or
linux/netlink.h
- allow scamper to do IPv4 ICMP echo and IPv6 UDP traceroute
without requiring root on linux.
- libscamperfile version 1.0.0
- sc_remoted:
- update remote control protocol to support session resumption
if the underlying TCP connection is interrupted.
- use HUP signal to reload TLS certificate and private key chain
- add -e pidfile to write PID to file, to make HUP easy
- sc_pinger:
- add utility to ping a set of addresses with ICMP echo, UDP, and
TCP-ack probes
- throughout:
- reduce number of warnings when compiling with -Wextra
- remove rcsid from all files

- scamper:
* do not dereference a null pointer when converting a tracelb node
with no IP address to a string, when generating json output.
- sc_bdrmap:
* allow the source IP address to be specified when probing with the
-S parameter.
- sc_wartsfilter:
* a new utility to select specific records from a warts file
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=23
* scamper
* escape hostname in json output for tracelb

- 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:
OBS-URL: https://build.opensuse.org/package/show/network:utilities/scamper?expand=0&rev=19
* 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.

- update to version 20171204:
- scamper:

packets which could have come from an off-path attacker.
- sc_radargun:
* add -d 2 option, which dumps interface IP-ID behavior classifications.
