Dnsyo使用实例
用100个线程同时查询所有DNS服务器上的结果。
$ dnsyo -t 100 -q ALL hi-linux.com Status: Queried 1097 of 1097 servers, duration: 0:00:42.016678 - RESULTS I asked 1097 servers for A records related to hi-linux.com, 324 responded with records and 773 gave errors Here are the results; 22 servers responded with; 199.27.79.133 39 servers responded with; 103.245.222.133 24 servers responded with; 23.235.47.133 18 servers responded with; 23.235.40.133 69 servers responded with; 185.31.17.133 14 servers responded with; 23.235.46.133 14 servers responded with; 185.31.19.133 14 servers responded with; 199.27.76.133 39 servers responded with; 23.235.43.133 17 servers responded with; 23.235.44.133 26 servers responded with; 185.31.18.133 15 servers responded with; 23.91.98.188 11 servers responded with; 23.235.39.133 2 servers responded with; 141.211.28.87 And here are the errors; 42 servers responded with; No Nameservers 22 servers responded with; No Answer 709 servers responded with; Server Timeout
使用--simple选项采用简单的输出模式，对于UNIX脚本是非常有用的。
$ dnsyo --simple hi-linux.com INFO QUERIED 500 INFO SUCCESS 222 INFO ERROR 278 RESULT 10 23.91.98.188 RESULT 30 103.245.222.133 RESULT 16 199.27.79.133 RESULT 11 23.235.47.133 RESULT 11 23.235.40.133 RESULT 16 23.235.44.133 RESULT 18 185.31.19.133 RESULT 24 23.235.43.133 RESULT 53 185.31.17.133 RESULT 13 185.31.18.133 RESULT 8 199.27.76.133 RESULT 4 23.235.46.133 RESULT 7 23.235.39.133 RESULT 1 141.211.28.87 ERROR 17 No Answer ERROR 18 No Nameservers ERROR 243 Server Timeout
使用--extended选项查询结果更加详细，包含其查询的服务器的名称和地址。
