Linux FC5: ping and dig no error, but firefox fails dns lookups

[EmosOohay]

When I ping or dig a domain name both succeed, but Firefox fails to
connect to the web site.

I could use some suggestions on what to try or what is the source of
the problem.

Thanks!

Update: Konqueror broswer works with out problem, so I guess it's a
Firefox problem or a configuration issue.

What message appears in the status bar before ff fails?

Can it reach a website by its IP address?

 

[EmosOohay]

"connecting to www.google.com..." then "connection has timed out", for example

using IP from dig in place of domain name seems to work

As I mentioned above, Konqueror broswer works with out problem.

Use konqueror. 😛

Uninstall FF, remove your profile (backup your bookmarks if you have any), and reinstall it.

Try clearing your DNS cache - maybe FF is using faulty stored data but Konquerer is sending a request every time?... This occasionally fixes problems with FF on windows for me.

 

[EmosOohay]

Well I restarted named and it didn't fix anything. Is this the correct way to clear DNS cache?

 

[n0cmonkey]

Only if bind was caching names...

 

[Nothinman]

By default there is no DNS cache in Linux, you shouldn't have bind installed unless you explicitly configured it AFAIK.

 

[EmosOohay]

Well, that explains why I couldn't find instructions on how to clear it!

I guess it's plan B, uninstall/reinstall, when I have time!
