commit 6702a95f2ea1a6a5b7c94437a87c1be6d0677733 Author: Jan Synacek Date: Mon Sep 12 12:50:58 2016 +0200 ping: fix error message when getting EACCES from connect() According to man connect(2), EACCES can be set either when pinging a broadcast address, or when a local firewall rule is in place. Easily reproduced by running "ip route add prohibit " and then trying to ping the address. diff --git a/ping.c b/ping.c index 34eb436..52b0f0e 100644 --- a/ping.c +++ b/ping.c @@ -655,7 +655,8 @@ int ping4_run(int argc, char **argv, struct addrinfo *ai, socket_st *sock) if (connect(probe_fd, (struct sockaddr*)&dst, sizeof(dst)) == -1) { if (errno == EACCES) { if (broadcast_pings == 0) { - fprintf(stderr, "Do you want to ping broadcast?
