This script will allow you to replace a traceroute output.

install nfqueue and NetPacket modules: sudo apt-get install nfqueue-bindings-perl libnetpacket-perl install Net::RawSock from the sources: http://www.hsc.fr/ressources/outils/rawsock/index.html.en and route needed protocols to nfqueue -A INPUT -p icmp -j NFQUEUE --queue-num 0 -A INPUT -p udplite -j NFQUEUE --queue-num 0 -A INPUT -p udp -j NFQUEUE --queue-num 0

specify the ip, which will be used for creating config to fake traceroute: host2:~# perl traceroute.pl 98.139.183.24

and test traceroute path from second host: host1:~# traceroute host2 traceroute to host2, 30 hops max, 60 byte packets 1 * * * 2 * * * 3 * * * 4 * * * 5 * exchange-cust1.dc2.equinix.net (206.126.236.16) 18.036 ms 33.963 ms 6 ae-4-0.pat1.nyc.yahoo.com (216.115.104.121) 53.996 ms 55.727 ms 59.957 ms 7 ae-2.pat1.bfz.yahoo.com (216.115.100.26) 57.398 ms 55.005 ms 52.492 ms 8 ae-4.msr1.bf1.yahoo.com (216.115.100.25) 52.382 ms 52.170 ms 51.944 ms 9 UNKNOWN-98-139-232-X.yahoo.com (98.139.232.107) 51.909 ms 51.792 ms 51.706 ms 10 et17-1.fab7-1-sat.bf1.yahoo.com (98.139.128.89) 52.059 ms 52.326 ms 52.674 ms 11 po-12.bas1-7-prd.bf1.yahoo.com (98.139.129.193) 52.403 ms 52.383 ms 52.290 ms 12 ir25.fp.bf1.yahoo.com (98.139.183.1) 52.159 ms 51.937 ms 51.678 ms 13 * * *
