Background: I recently did a fresh install of FC10. I previously ran FC6 with no problems. I am on an older Toshiba Satellite laptop and I can use either Eth0 or Wlan0. I have been running Linux for years, though I would not call myself an expert (I can fix problems and do things seeing other examples).
My problem: Any program that needs to access the internet gets mixed results. For example, using Firefox I can navigate to Google fine, I cannot access Adobe or Yahoo ever. Yum cannot connect to the Adobe repo and it is hit or miss with RPMFusion. This is all consistent. It also happens regardless of interface I am using (Eth0 or Wlan0). It looks like when first contacting a site, things are very slow, but once the site is contacted things go fast with the exception of sites that never respond like Yahoo or Adobe. I can download files at expected speeds.
If I run host www.adobe.com
I get this:
is an alias for www.wip3.adobe.com
has address 126.96.36.199
mail is handled by 10 smtp-relay-1.adobe.com.
mail is handled by 20 smtp-relay-2.adobe.com.
If I run host www.yahoo.com
I get this:
is an alias for www.yahoo-ht3.akadns.net
has address 188.8.131.52
It appears I can really get to these sites and resolve them, no idea why programs cannot (i.e. Firefox or Yum).
What I've done: I have switched over to use OpenDNS. I have followed the suggestions for a DNS bug fix on the FedoraFaq page for FC10. I have yum removed NetworkManager. I have disabled services for IPv6 and also disabled it specifically in FireFox using about
My current setup: I am running the network service, run levels 3 and 5 using OpenDNS . DHCP is enabled.
Any help or thoughts are greatly appreciated, I'd love to figure this problem out and put it to bed.
