HW:
Lenovo T520 laptop with MS WIN 7
OR
dedicated PC (DELL GX 280)
SW:
CentOS 6.5 (64-bit) installed using VMware Player on MS WIN 7 host
CASE A) -- BRIDGED networking selected
CASE B) -- NAT networking
OR
CentOS 6.5 i(32-bit) nstalled on real HW (DELL OptiPlex GX 280)
___issue____ at hand:
The default Firefox ESR browser (17.0.10) does not find many web pages.
regardless of the system (virtual - bridged or NAT OR real HW)
For example:
https://www.google.com/ works
When I enter into search field string 'opera browser'
https://www.google.com/search?q=opera+browser&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:unofficial&client=firefox-a
I do get a lot of results back. So far so good.
Then I click on the first searched link http://www.opera.com/
I get back
Server not found
Firefox can't find the server at www.opera.com
Then I open gnome-terminal and type
ping www.opera.com
I get back __nothing__
[igor@localhost ~]$ ping www.opera.com
PING www.route53.opera.com (54.244.236.138) 56(84) bytes of data.
but
when I type
ping opera.com
I get back
[igor@localhost ~]$ ping opera.com
PING opera.com (185.26.182.79) 56(84) bytes of data.
64 bytes from front-ams.opera.com (185.26.182.79): icmp_seq=1 ttl=41 time=174 ms
64 bytes from front-ams.opera.com (185.26.182.79): icmp_seq=2 ttl=41 time=122 ms
========================
another example
========================
http://www.delo.si/ works
http://www.dnevnik.si does __not__ work
http://www.centos.org/ works
but when I click on the link Special Interest Group on the same page
http://wiki.centos.org/SpecialInterestGroup , the link does NOT work.
I get back
Server not found
Firefox can't find the server at www.opera.com.
:::important:::
All the examples from above work flawlessly on the MS WIN 7 on the
same laptop, the same ETHERNET cable connected to the same switch hub
with the same router at the same time.
[Reminder: CentOS 6.5 runs on VMWare on WIN 7]
Any hint, FAQ, pointer to RTFM is more than welcome
I am puzzled, please help
