in reply to ANNOUNCE: JavaFu.com Open For Business

Javafu.com may be open for business, but it appears to be behind something like a firewall: 
bash-2.04$ ping -c 10 javafu.com
PING javafu.com (216.168.224.70): 56 data bytes
36 bytes from sl-gw2-rly-0-0-0.sprintlink.net (144.232.25.251): Commun

    In fact, it is not behind a firewall. What is IS behind is my ISP, who filters port 80, claiming that they're doing so due to the 'Red Alert' virus. This is a blatant lie, where they charge businesses 3 times what they charge me for the same service, just to allow access to port 80. Because you know, a single home user would never run a web server right? Ugh... I called & told them "I don't even use windows!" but they are conveniently ignorant as to what the hell I'm talking about. "What's a port?" I got back... nice eh?

    So naturally, I rerouted everyone to port 81 via the DNS server, which is off-site. This solves the problem, unless YOUR firewall doesn't let you out through 81... Which now seems to be a recurring problem with a number of users...

    Time to switch ISP's I think...

    OR, I might try pushing traffic over to port 443. I'll have to see if they've filtered that one too... :\

    Also, just for nothing, I usually kill ping & finger anyway, so relying on just that isn't enough. No mac servers (<OSX) implement ping, for example.



    Wait! This isn't a Parachute, this is a Backpack!
