RE: TCP not working over ppp connection (WAS: 5th day using Linux...)
I am certain that my ISP is not blocking TCP traffic. When using the same
account and the same modem in Windows, everything works fine. Also remember
that when I had my web server set up behind my Linux box, I was able to use
TCP outbound and inbound without an issue. This is something dorky having to
do with the Linux box and TCP. Is there some package I need to install
maybe?
Also, why would my post be burred? I am unfamiliar with the way this mailing
list works but have been surprised by the low number of responces... I do
not want to SPAM the list, but I really need to get my box online...

this is fairly normal stuff here, and should only have to be done once.
because modems can reside at a variety of different /dev/tty*'s the
/dev/modem link typically has to be set up manually (in my experience). The
other alternative is to make your dialer point to /dev/ttyUSB0.

I know naught of dynamic-DNS, but is it possible that TCP is being blocked
upstream from you? I wouldn't know how to check this, but maybe the problem
is with your provider and not your configuration?
Also, FTR, your thread showed up buried inside another thread in my mailer
here, which could explain the low-level of response to your problems. If you
don't get much more help in the next day or so, try reposting under a new
subject to get to the top level in people's readers.
