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 <ipaddr>" and then
|
||
|
|
trying to ping the address.
