scamper
Actively probes the Internet in order to analyze topology and performance.
TLDR
Execute the standard option (traceroute) to a destination
$ scamper -i [192.0.2.1]
Execute two actions (ping and traceroute) on two different targets
$ scamper -I "[ping] [192.0.2.1]" -I "[trace] [192.0.2.2]
Ping several hosts with UDP, use a specific port number for the first ping and increase it for each subsequent ping
$ scamper -c "[ping] -P [UDP-dport] -d [33434]" -i [192.0.2.1] -i [192.0.2.2]
Use the Multipath Discovery Algorithm (MDA) to determine the presence of load-balanced paths to the destination and use ICMP echo packets to sample with a maximum of three attempts, write the result to a warts file
$ scamper -O [warts] -o [path/to/output.warts] -I "[tracelb] -P [ICMP-echo] -q [3] [192.0.2.1]"
Execute a Paris traceroute with ICMP to a destination and save the result in a compressed warts file
$ scamper -O [warts.gz] -o [path/to/output.warts] -I "[trace] -P [icmp-paris] [2001:db8:dead:beaf::4]"
Record all ICMP packets that arrive at a specific IP address and have a specific ICMP ID in a warts file
$ scamper -O [warts] -o [path/to/output.warts] -I "sniff -S [2001:db8:dead:beef::6] icmp[icmpid] == [101]"
