After DNS Install Unable to connect to internet,
am able to ping inside my network but not outside. had problems with DNS starting ran the fix to update the apparmor profiles this fixed DNS , now I am unable to connect outside my local network. I think it has something to do with the DNS forwarder. I had to add the ISP’s DNS server to the NIC in the beginning to access the internet

fixed 11.2 under network settings , global options uncheck change default route dhcp

You are very short in your explanations.

What do you mean by “DNS install”? DNS (Domain Name System) is a world wide database. You can use this as a client (asking for name resoltion) and/or as a service (running bind). What did you install? And when you did install something, did you also start it, or do you have those problems after a simple install?

You say you can not connect to the outside world (via your router). This must have to do something with routing (or a loose cable), not with DNS. When DNS is broken you can not ask for name resolving on the Internet, but connection is still possible.

I am running bind 9.6. When I start the named service I am unable to access the internet through an internet browser. When I stop the named service I am able to connect to the internet through firefox. I thought it might be my zone file setup ( I have another thread in for that ).

More Info on issue, Thank you for your help

I currently have a local domain server inet1.local and am using it as a web server for inetmining.com

Unable to access the internet with bind/named started. New install , accessed
the internet before installing bind , ran fix for apparmor update profiles to
get bind/named to start. Set dns zone started named then was unable to access
the internet , unchecked network settings , global options, chnage default
route dhcp. started running , reboot . No access to the internet again,
shutdown bind.named . Am able to access internet. with bind /named running am
able to ping witin lan but not able to access the outside

Reproducible: Always

Steps to Reproduce:
1.start dns bind/named in yast no access
2.shutdown bind/named in yast able to access
3.
Actual Results:
1.start dns bind/named in yast no access
2.shutdown bind/named in yast able to access

I believe i fixed the the name resolving issue by updating my zone file.

In the other thread I also tried to explain that it is not very likely that **connection **is lost when you switch on your DNS service. It is however likely that your name resolving is broken.

That means that your browser will tell you that it cannot **resolve **forums.opensuse.org, but that you will still be able to **connect **to 130.57.4.15.

When I try to go to the ip address I get the same from the browser. Bare with me I’m intermediate to linux


Server not found
          

     
        
        
       

Firefox can't find the server at 130.57.4.15..

        


        
        


    *   Check the address for typing errors such as
          ww.example.com instead of
          www.example.com

    *   If you are unable to load any pages, check your computer's network
          connection.

    *   If your computer or network is protected by a firewall or proxy, make sure
          that Firefox is permitted to access the Web.

When I see ther erropr message I am afraid that you added a . (dot) at the end of it when typing the URL in the address bar of FF. You should type:

130.57.4.15

You never saw an IP address before?
That last dot is of course the dot that finishes my sentence. Not the IP address.

I was being specific to your response . Linux is specific in some of it’s needs. I am new to linux with alot of bad habits from windows. I’m very motivated to learn this architecture.

I was able to connect to this address . When I tried other IP Address’s it failed to connect. How would you suggest I start to troubleshoot the name resolving being broken?

I suppose it is even true in windows that when you add a dot at the end of an IP address, you get no connection to that system.

The name resolving being broken is because (as you explained yourself) you start using bind on your system. And as we have seen in your other thread, its zone files are broken.

We better leave this thread and concentrate on the other one.

I only answered to this thread because:

  1. you did not seam to understand what DNS is, what DNS-server software (bind) and what DNS client software (resolver).

  2. you did not seem to understand the difference between network connection (using cables, routers, modems and the TCP/IP protocol) and name resolving (where DNS is for).
