puudeli's scratchpad

SOLVED: setsockopt(SOCKET, SOL_SOCKET, SO_LINGER, pack('II', 1,0)) SO_LINGER takes two arguments, on/off and time

Why does setsockopt give me: setsockopt: Invalid argument at ./socket_connection_flooding.pl line 55.

use Socket qw(:all); use POSIX; my ($socket, $remote,$port, $iaddr, $paddr, $proto, $line); $remote = shift || 'localhost'; $port = shift; $iaddr = inet_aton($remote) || usage("no host: $remote"); $paddr = sockaddr_in($port, $iaddr); $proto = getprotobyname('tcp'); socket(SOCKET, PF_INET, SOCK_STREAM, $proto) || die "socket: $!"; setsockopt(SOCKET, SOL_SOCKET, SO_LINGER, pack('i',0)) || die "setsockopt: $!"; connect(SOCKET, $paddr) || die "connect: $!"; close (SOCKET) || die "close: $!";

[marto]: good morning all, TCIF
[Corion]: Hi marto! Indeed, Crunchy be thanked!
choroba had a Christams party at work yesterday. Slow morning today...
[Corion]: I guess I should not read some discussions on HackerNews - the crowd there is weirdly different - "you have to stay current in tech" (by following all the latest JS trends) is a meme there, but it doesn't really match my experience
[Corion]: At least in my area, experience can beat most new tech anyway because most new tech is just a rehash of things abandoned in the 70s and we still have a lot of that ;)
