Looks like either the upstream server did not answer after accepting the
connection (may be caused by full or defective disk drives on their
site) or it disconnected but leafnode didn't notice.

Can you tell if that other server dropped the connection (check
"netstat" output) at that time? A "tethereal -s5000 -n host
news.mhogaming.com and port 119" (use tcpdump if you don't have
tethereal, same options IIRC) might also be useful, but make sure it
does not reveal your password should you need one.

You may need to give tcpdump/tethereal an option like "-i tun0" (FreeBSD
PPP e. g.) depending on your network configuration.
