[Spread-users] Newbie: 2 servers, 1 linux, 1 NT, each has one deamon running, locally work fine, but can't communicate over the internet

Hello John,
Thank you very much for your response. I will download the patches and
use it.
I have one more query. The situation is like this
I run the spread daemon, then I connect two to three clients. When I
close the client connections I still see that the socket opened by the
spread daemon does not die.
The spread daemon does not close the socket once the client closes the
connection. I see that the when the client closes the connection the
socket is in "TIME_WAIT" state. The after 1 minute it goes to
"CLOSE_WAIT" state. But then the "CLOSE_WAIT" state does not go away. It
stays as long as the spread daemon is active and goes away only when the
spread daemon dies.
Question: Is there a way to close those connections ?
Regards
Vikas

Mr. Vikas,
That bug has been reported in the past and is already fixed in the
development version of Spread 4.0.1. We just haven't gotten around to
releasing the patch version yet officially, although we probably should
do that soon.
If you want to get access to the most up-to-date version of Spread with
patches, etc., then follow the instructions for getting access to
Spread's cvs/svn code repository on spread.org.
If you want to continue using Spread 4.0.0 instead, then here is the
actual bug fix we made in our development version in diff format.
The problem was that I was casting a char* to a 32b integer* when I
shouldn't have been.
