ALT Linux Bugzilla – #61252

...везде, где предлагается tracepath(1).

Раньше была причина исключить traceroute и включить tracepath: первая программа у нас плохо сопровождалась, её апстрим не развивался. По прошествии доброго десятка лет, сейчас, она продолжила развитие и хорошо мейнтейнится в сизифе.

По сравнению с tracepath, она умеет:
  -N squeries  --sim-queries=squeries
                              Set the number of probes to be tried
                              simultaneously (default is 16)
  -t tos  --tos=tos           Set the TC (IPv6 traffic class) value
                              for outgoing packets
  -l flow_label  --flowlabel=flow_label
                              Use specified flow_label for IPv6 packets
  -q nqueries  --queries=nqueries
                              Set the number of probes per each hop. Default is
                              3
  -e  --extensions            Show ICMP extensions (if present), including MPLS
  -A  --as-path-lookups       Perform AS path lookups in routing registries and
                              print results directly after the corresponding
                              addresses
  -M name  --module=name      Use specified module (either builtin or external)
                              for traceroute operations. Most methods have
                              their shortcuts (`-I' means `-M icmp' etc.)
  -O OPTS,...  --options=OPTS,...
                              Use module-specific option OPTS for the
                              traceroute module. Several OPTS allowed,
                              separated by comma. If OPTS is "help", print info
                              about available options
  -w MAX,HERE,NEAR  --wait=MAX,HERE,NEAR
                              Wait for a probe no more than HERE (default 3)
                              times longer than a response from the same hop,
                              or no more than NEAR (default 10) times than some
                              next hop, or MAX (default 5.0) seconds (float
                              point values allowed too)
  -z sendwait  --sendwait=sendwait
                              Minimal time interval between probes (default 0).
                              If the value is more than 10, then it specifies a
                              number in milliseconds, else it is a number of
                              seconds (float point values allowed too)
  -s src_addr  --source=src_addr
                              Use source src_addr for outgoing packets
  --sport=num                 Use source port num for outgoing packets. Implies
                              `-N 1'
  --fwmark=num                Set firewall mark for outgoing packets
  --mtu                       Discover MTU along the path being traced. Implies
                              `-F -N 1'

Особое внимание на последний пункт.

Картина, которую можно составить по выхлопу, у traceroute(1) тоже полнее.
