	Before I try could this issue be related to some of these
kernel parameters?

	I ask it because I decided to comment these lines (on my
NATted desktop and on the server) and until now I don't have the problem
anymore. But I'll keep testing all day and if the problem comes back
I'll try the patch ok?

	It's my nntp server:

nntp://news.abusar.org

	You can post test messages on grupo "u-br.teste".

	But there's an issue. My connection was stalled mainly when I
ran some application with sudo (for example fetchnews etc). Then I'd do
an nmap -sS and the connection would come back alive. Sometimes it
would be necessary a nmap on my desktop (local machine) and sometimes
on the server (news.abusar.org).
