In my default installation, firefox can not resolve urls. When I give the ip address, it is working well. Otherwise it doesn't work. 'ping -c 3 google.com' is working again. I thought there must be some problem with SELinux or Firewall. As I am a new comer, I have disabled iptables and ip6tables and also SELinux security. Then rebooted. Even then I couldn't connect to any url from firefox. I have tried to enable all the services which relate to dns and networking. What should I do ? I opened a terminal, 'su', then typed 'firefox' ( as root) then an error message has come. It is given below ...
"Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)"
Next problem is ... the system has shown about 12 updates. When I selected update, it is eternal.
Please help.
