dns not working with wifi?
I have a vodafone "pocketwifi R216H" WiFi linking my home machines to the Internet and a Linode remote server just provisioned with an OS and Apache2 (including ~/html/index.html). DNS is hosted by Crazydomains.
Code:
Name Server 1 ns1.linode.com 162.159.27.72,2400:cb00:2049:1::a29f:1a63 I entered the parameters "ns?.linode.com" which prompted the addition of the ipv4 and ipv6 which seems to belong to Linode but I am only guessing that the 'auto-completion' is normal and correct rather than self-serving. I suspect the cause is the wifi modem (dynamic ip?) or the DNS hosting is blocking resolution to IPs outside their own. I have found two solutions that do not work for me: edit /etc/resolv.conf (without reboot) or dhclient.conf trying to add 8.8.8.8 and 8.8.4.4 (with reboot). Perhaps it is not even possible under WiFi and I might have to test any website put on the Linode in some other way than entering the hostname in the browser. Can someone suggest how to resolve the problem or point to suitable howto or how to find if the DNS hosting is blocking something? Thank you for your help |
To test whether linode is resolving your domain run the commands below and look for the ANSWER section:
Code:
dig @ns1.linode.com example.com A |
Thank you very much for the answer. I got the following results which I do not understand although it appears to me that my dns may not be set correctly with linode although it is not the only problem.
Can you explain what that result means? Giving parameter "A" or "AAAA" gave the same result in both cases. Code:
dig @ns1.linode.com nobla.org A Code:
dig @8.8.8.8 nobla.org A |
dig @ns1.linode.com nobla.org A doesn't time out for me, so I'm going to say your server is not resolving ns1.linode.com properly.
What's in your /etc/resolv.conf? However, that query does not resolve the IP for nobla.org, so, yes, the A record for that domain name is not set up correctly in the linode name servers. As those are the name servers for the domain, if they are not correct, the domain name will be unreachable. |
Code:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) |
I don't think your domain is in the linode nameservers. There is no nameserver for it listed in DNS.
Code:
dig nobla.org NS Code:
jwhois nobla.org |
