The problem is that a connection sitting at the greeting isn't receiving any
data. It is in the nature of TCP that it can't detect a lost connection
until you try to send it data.
There's a keepalive flag you can set on the socket (on most OS's), that will
cause it to periodically send probe packets to see if the socket is still
connected, though this can take over 2 hours to detect a disconnection (RFC
1122).
int x = 1;
if (setsockopt(desc, SOL_SOCKET, SO_KEEPALIVE,
(void *) &x, sizeof(x) ) < 0)
{
perror( "SO_KEEPALIVE" );
close(desc);
}
Well, some OS's, that 2 hours thing is configurable.
The other option is to add a timer to the descriptor like the one in
char_data, and disconnect when it gets too high.
