+This is simple traffic generator script for stress tests.

+(FreeBSD and Debian Linux ships with this version).

+Script will send number*$Q UDP packets

+Note: for stress test you must turn off ICMP rate limit on target machine:
+Linux: sysctl -w net/ipv4/icmp_ratelimit=0
+FreeBSD: sysctl -w net.inet.icmp.icmplim=0
+Solaris: /usr/sbin/ndd -set /dev/ip ip_icmp_err_interval 0
