| H A D | ping.c | diff 125605 Sun Feb 08 19:59:17 MST 2004 iedowse Certain ICMP error replies cause ping to perform a reverse DNS lookup on an IP address from the packet (such as the IP that sent a TTL exceeded error). If the DNS lookup takes a long time, ^C will appear to be ineffective since the SIGINT handler just sets a flag and returns. Work around this by exiting immediately on receipt of a second SIGINT when DNS lookups are enabled. PR: bin/4696 MFC after: 1 week |
