Preliminary comment: I added the list back in. Please, let's keep 
discussions of this sort on the list.

The DNS resolution is not a problem; that part should still work. To do 
what I described, you do need to change the URL, which I suppose means 
changing what you "advertised". The moral of this story is: don't 
"advertise" a URL until you've tested it successfully.

There may be other workarounds, involving redirection, but I believe they 
require that http://www.somename.com resolve to some other IP address (one 
without a port-80 restriction), where a server can redirect the traffic to 
(for example) http://www2.somename.com:8080 .

>BTW, why do some ISPs block port 80?

Ask them, not me. I've seen many excuses offered for this practice, some of 
which I believe, others of which I dismiss as self-serving claptrap ... but 
that's just my opinions. Some ISPs include in their Terms of Service for 
low-end plans a prohibition against running servers, and this is one way 
they enforce that policy.

My first Mozilla install

[Dan Bentson-Royal]

I have just installed RH7.2 and Mozilla suggested upgrading. I fumbled
around between GUI and terminal windows and finally got it.

I have the Gnome icon for Mozilla properly pointing to:
/usr/local/mozilla/mozilla

But my non-root user's Gnome-Mozilla icon (the lizard head) still points
to the old version. How do update all users to know where the new
Mozilla application is?

Mozilla update - EZ question

[Dan Bentson-Royal]

I just re-read my earlier post and saw it was less than clear. I will
repost again to try and clean it up a bit...

I have just installed RH7.2 and when I ran Mozilla for the first time, it suggested that, for security reasons, Mozilla needed to be upgraded. I fumbled
around between the GUI and terminal windows and finally got the latest
release of Mozilla downloaded and installed. For me, this was a big step
and quite a coup. However...

As root running Gnome, I have the Gnome icon for Mozilla properly pointing to the location of the new version of Mozilla - which is:
  /usr/local/mozilla/mozilla
 
But my non-root user's Gnome-Mozilla icon (the lizard head) does not 
point to that new install of Mozilla - it invokes the old installation.
I could manually change it, but I know there must be some way to have
this updated for all users. Is that correct? So that when I create
accounts on this machine, they will all use this newest version of
Mozilla. Should I delete the old version and move the new one into the
same location (/usr/bin/mozilla)?

I can think of several ways, however i think the easiest would be to simply 
delete the old version or rename it, then create a symlink in /usr/bin called 
mozilla.
ln -s /usr/local/mozilla/mozilla mozilla
AFAIK that should work.
