Why - are you running a web _server_ on a dialin?
Web server? Sorry, but I don't see where I said that I was running a web
server. At 26k that would probably give the world less than stellar
access. No web server. Just a Smoothwall in firewall mode only.
Then you probably don't want any ports open on the Internet side of
As 'netstat' is showing you - when you want to connect to a remote web
server, your system opens a connection from a "high port" (meaning some
port above 1024) on your end to port 80 on the remote server. The reply
from the server comes back from it's port 80 to the "high port" that
you have opened. Thus, there is no need for port 80 to be open on _your_
end of things. That's the reason for the question.
and where are you getting these messages?
In the browser (firefox) bottom bar. Looking up Google.com. Waiting for
Google.com. Timeout or server reset popup some times if it gets real bad.
OK - browser problems.
At least you didn't ask me why I don't switch to broadband - everybody
Well aware that broadband is not universally available. Not everyone
believes that though.
No, just running Firefox as a browser and not much of that - too slow.
But it seems that you've enabled extra services on Firefox. Do remember
that a browser is a "try to do all" tool that was invented long after the
other services were available on the Internet. Some people use a browser
for everything because it's the only tool they've ever bothered to learn
about, but but news, mail, FTP, and such were around decades before that,
and have their own tools that are generally more suitable.
I go back to what IBM used to call 75 baud start-stop in the 60's. An
early term for what would become known as asychronous communications. I
have stuffed a phone in a few rubber lip pairs.
They're called "acoustic couplers, but I got rid of my last one in 1983
when I got a Hayes modem for the PC. That was fortunate, as I replaced
the WECO 500 desk phone with a "Princess" phone which wouldn't have fit
in the coupler anyway.
This was my first thought - what have I loaded that is trying to phone
home? The answer is nothing new has been loaded besides perl-TK and
Debian security updates for a couple of years. Besides, I cranked up
another machine that is raw - that is, nothing but a primary Debian load -
that I use for learning and it got the same incoming stuff.
Sounds like all the bells and whistles are enabled in the browsers.
