Re: socket lost by buffer overflow

You should check the return of the print to your socket for undef. This means the other end of the connection is gone. You don't have any code, so this is just my assumption. Change your code to do something like this:

my $sockstatus;
while (<YOURLOOP>) {
    $sockstatus = print $socket $data;
    last unless $sockstatus;
}

hth!

Hi :-) Dug's method will handle when the os notifies us when the tcp keepalive mechanism determines that the client is no longer there if the client doesn't close the tcp connection itself. elwarren's method will proactively perform a 'ping' to the client to determine if the client is no longer there. Which to use? Depends if you when you need to know when a client connection disappears. Do you really need to know if it disappears within 10 seconds? IMHO, a connectionless (udp based) would be preferrable. There is a simple example in the Perl Cookbook IIRC. Jason L.

The problems seal3 is seeing is on writing to a socket, not reading from it. I just posted the simplest solution. seal3 can you show us your code?	[reply]
