Please dont post without quoting something from the parent. Without
any quoting for context it's difficult for some one to come behind and
know what you are replying to. If you find this too difficult with
google groups, your ISP likely runs a news server offering this and
other groups. If not, news.individual.net has very cheap yearly
subscriptions. Either way, you'd also get to use a real news reader
instead of some bastardized web interface to usenet.

In the future you can check this by running tcpdump on the target
machine, then using telnet, nmap, or nc to send a packet to that
particular port. Even if a firewall on the target machine disallows
the packet, tcpdump will display it, letting you know that it was
received. If the packet is never received, you can be reasonably sure
that it was blocked by an ISP along the way.
