scamper

Actively probes the Internet in order to analyze topology and performance. Includes some tools that start with sc_, for example sc_warts2text or sc_ttlexp. More information: https://www.caida.org/catalog/software/scamper/.

• 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"
