unable to browse most sites
 
hi, i am able to ping certain sites but most i am not able to connect to:
Code:

i think its related to ipv6 somehow.

thanks,

Ping isn't a great tool but helps some.

Your reply was ipv6 which makes me think that ipv4 isn't enabled.

May be some xbmc(kodi) issue if installed and it is a very modern kernel there may be other issues.

What does ip command tell you about network?

Generally you can disable ipv6 in browser even if network is disabled for ipv6 to correct it.

Need ip command results I think first.

jayjwa 07-28-2016 05:15 PM

duckduckgo doesn't seem to have an ipv6 address. Looks like you've got ipv4 disabled or blocked some place. You may also want to check sysctl -A output (grep ipv4), iptables, and routing info while looking for the problem. Since you can't reach most sites, this doesn't say much good for ipv6 adaptation. :(

since this pc is not setup to dhcp, i logged into gnome and went to network preferences. in the ipv4 tab i typed in the ip address of my router in the gateway and dns fields.

jayjwa 07-30-2016 10:57 PM

You don't seem to have an ipv4 default route setup. Should look like

Code:

ip route show dev eth0
default via 192.168.10.1
192.168.10.0/24  proto kernel  scope link  src 192.168.10.2

You can add a default route via ip route command. I see you marked this "solved" but for another way to fix the problem I've listed the above.
