very strange... this is the option to set the timeout of 10sec for the
connection to the client. It is done by the setsockopt syscall.
The piece of code is the following:
eval {
# Set a timeout on the socket.
setsockopt(SOCK, SOL_SOCKET, SO_SNDTIMEO, pack('LL', 10, 0)) or
die "error: cannot set SO_SNDTIMEO option to socket\n";
setsockopt(SOCK, SOL_SOCKET, SO_RCVTIMEO, pack('LL', 10, 0)) or
die "error: cannot set SO_RCVTIMEO option to socket\n";
# Connection to the client.
connect(SOCK, sockaddr_in(8181, inet_aton($ip))) or
die "error: connection failed\n";
};
The first strange thing is that since it is in an "eval" construct the
execution should proceed, simply using socket without timeout, but
proceed... the second strange thing is why the option is not set. Maybe
LL (long long) is assembled in a different way in x86_64, but AFAIK 'L'
should be _exactly_ 32-bit in _all_ architectures. To check it can you
try to run:
perl -e 'print length(pack("LL")), "\n";'
The right result should be 8.
Cheers,
Andrea
