Hello List,
I have two browsers, the Firefox and Opera on F14. Both can watch
without any problem
youtube videos and access almost any site except for Globus (
http://www.globus.org/ ). Using the Firefox of F7 on another box, I
found no problem of accessing that site.
Does anyone have an explanation?
Thanks in advance.

1. check /etc/hosts
2. Firefox blockers ?
Tools - Add-ons - Extensions
3. Opera blockers ?
Tools - Advanced - Blocked Content...
4. check firewall rules

Are you having problems accessing the Globus site or viewing the videos?
Using the Firefox of F7 on another box, I
found no problem of accessing that site.
So it's likely your network is configured properly, although your
workstations may be configured differently.
The videos on the Globus site are .mov files. Perhaps you don't have
correct decoders in place.
Please tell us more about the problem you are having.

Is the following the right command to invoke?

Please advise the next step.

It is problem of accessing the globus site. The Firefox was loading
with an infinite mount of time, nothing turned up. Yes, you were
guessing right, I can not watch mov video, e.g.,
http://www.physics.harvard.edu/QFT/video/01-opening.mov
But this is not the main problem at a moment.
Please tell us more about the problem you are having.
Probably I need additional plugin, apart from those already there. I
will be glad to try if you have some clue. Thanks for the response.

Does Network Monitor show any activity at all, or is it idle? If
you
don't already have it active, add it to your panel and try again.
The network is active. In fact, I open several tabs for accessing some
other sites at the same time, and only the http://www.globus.org/
which does not turn up.
I have now two PCs, each with Firefox and F14. Both can not access that site.

That's not what I was asking about. If you try to reach that site and
do nothing else as far as the network goes, do you see any activity at
all? I want to know if you're actually getting anything from that site
or if you completely stop receiving data.

I do not know what Opera version you have, but on my ver 10.10 and higher
I can see the Menu Bar:
File Edit ... Tools Help
If you can not see it then you have to configure the browser:
in the upper left corner, on the second bar, there must be an icon (first one)
- click your mouse on it and a menu pops up, on which you select
Show Menu Bar
Any way,
let's concentrate on Firefox only for now to fix the problem with that site.
Now tell me how do you access Internet from your machine:
- your machine talks directly (dial-up, ethernet, etc) to ISP ?
- your machine has some kind of modem/router (ADSL, etc) that in turn talks to
your ISP ?
- your machine is part of a network (corporate ?), thru which you reach ISP
and Internet ?
Just to avoid any surprises in your Firefox config, make sure there is no proxy
between FF and your machine/outside network:
Edit - Preferences - Advanced - Network - Connection Settings
note (and tell us) what was in there, and then configure it to:
No proxy
then click OK, and Close to finish config procedure.
You may restart Firefox to make sure it took effect.
In Firefox,
- clear your cache
Tools - Clear Recent History
Time range to clear: Everything
Details: check off all items
click Clear Now
- now input:
www.globus.org
and tell us what exactly is the response you get ?
- now input:
http://192.5.186.47
and tell us what exactly is the response you get ?
Give us unedited output of:
$ ping -c 1 www.globus.org
$ ping -c 1 192.5.186.47
$ dig www.globus.org
$ dig 192.5.186.47

That implies a routing issue, outside your box. (I used to do senior
support for an ISP; I know these things.)

The machine is probably behind a firewall that doesn't accept pings to
prevent DDOS attacks. Try this:
traceroute www.globus.org
If you get lots of timeouts, you may need to use ICMP packets, but for
some weird reason, that requires root. (I do it often enough that I've
set suid on /bin/traceroute but I'm not suggesting anybody else do
that.) If the above gets complaints, use this instead:
su -c 'traceroute -I www.globus.org'
Will show you how close you're getting and if there's any routing
problems. I used su -c because I *don't* use sudo on my home machine
and don't expect anybody else to either. YMMV, and if you're more happy
with sudo, substitute as needed; it's your machine, not mine.
Once you've documented where the issue is, call your ISP and let them
deal with it because that's what you're paying them for.

One thing which is strange for me is that another box running FC7 in
the same internet line can access the site. It is an indication of
no need to call ISP as the problem is in the side of my box.
Please be available to give more suggestions.
Thanks in advance.

Correct. It's possible that there's something in the source of the page
that your copy of Firefox doesn't like. I belong to a site that pays me
to take surveys. Once in a while, the first page of the survey either
never stops loading, or loads to a blank page. I've tried viewing the
page source, but I've never figured out what Firefox objects to. Tish
happens.
