| SING stands for 'Send ICMP Nasty Garbage'. It is a tool that sends ICMP packets fully customized from command line. Its main purpose is to replace and complement the ping command, adding certain enhancements as fragmentation, send and receive spoofed packets, send many ICMP information types (echo as the old ping, address mask, timestamp, and router discovery) and errors (redirect, unreach, and time exceeded), and send monster packets. It also supports loose and strict source routing and record routing. |
