in thread Timeout for an established connection

What OS are you using?

It looks like all linux kernels since 2.6.32 has implemented TCP_USER_TIMEOUT; which would definitely be the better option if it is available to you.

This is something I have long done.

Hm. Makes me wonder why you are asking here, if you already have a solution?

    Maybe this is an error in the syntax? "setsockopt($sock, 6, 18, pack("QQ", 5, 0))"

    >Hm. Makes me wonder why you are asking here, if you already have a solution?
    Because this solution does not seem to me the best.
      Maybe this is an error in the syntax? setsockopt($sock, 6, 18, pack("QQ", 5, 0))

      That does look suspect to me.

      According to this (4th post), the parameter is the address of an int containing the timeout in milliseconds. Given you are on a 64-bit build I'd expect to use something like this in Perl:

      setsockopt( $sock, 6, 18, pack( "Q", 5000 ) )

      Or possibly:

      my $userTimeout = 5000; setsockopt( $sock, 6, 18, \$userTimeout );
