Hi, In my attempt to explore astraceroute, i am constantly getting 'no answer', can anyone point out what is the problem?
No firewall on the host. bash# astraceroute -v astraceroute 0.6.2 (Circlon), Git id: (none) autonomous system trace route utility http://www.netsniff-ng.org bash# astraceroute -i eth0 -H example.com AS path IPv4 TCP trace from 192.168.1.9 to 93.184.216.34:80 (example.com) with len 40 Bytes, 30 max hops Using flags SYN:0,ACK:0,ECN:0,FIN:0,PSH:0,RST:0,URG:0 1: t[ 3280 us] 192.168.1.1 2: ?[ no answer] 3: ?[ no answer] 4: ?[ no answer] 5: ?[ no answer] ... bash# astraceroute -i eth0 -S -H example.com AS path IPv4 TCP trace from 192.168.1.9 to 93.184.216.34:80 (example.com) with len 40 Bytes, 30 max hops Using flags SYN:1,ACK:0,ECN:0,FIN:0,PSH:0,RST:0,URG:0 1: t[ 3246 us] 192.168.1.1 2: ?[ no answer] ... bash# astraceroute -i eth0 --port 80 -H example.com AS path IPv4 TCP trace from 192.168.1.9 to 93.184.216.34:80 (example.com) with len 40 Bytes, 30 max hops Using flags SYN:0,ACK:0,ECN:0,FIN:0,PSH:0,RST:0,URG:0 1: t[ 3020 us] 192.168.1.1 2: ?[ no answer] ...
