pinger_program

---

Squid uses the pinger program to send ICMP pings to origin server sites. Squid uses these ICMP measurements to estimate network proximity. Note that the pinger program must be installed as setuid root because it opens a raw ICMP socket. To enable the ICMP measurement features, use the ./configure enable-icmp option.
