Pinging > the web address fails What do you mean by "pinging a web address", the name of the server? If you can ping a DNS server by it's IP address, but not by it's fully-qualified domain name (FQDN), then you can stop right there as your DNS configuration/connection is not working. (Being able to reach a site using PING only really tests that you can reach it with the ICMP protocol over IP. It doesn't test anything more about reachability to a particular host, the initial DNS lookup done by ping if needed is really just a side effect). To test DNS, once you think you have resolv.conf correct, use "host <FQDN>". If this returns nothing, then DNS is broken. You can make it more verbose with "host -v <FQDN>". You can also use "host" to force it use a particular DNS. For instance Google have magnanimously made available 8.8.8.8 as a freely available and easily remembered DNS. To test it you can do something like "host www.google.com 8.8.8.8" to get the following result. $ host www.google.com 8.8.8.8 Using domain server: Name: 8.8.8.8 Address: 8.8.8.8#53 Aliases: www.google.com is an alias for www.l.google.com. www.l.google.com has address 74.125.19.106 www.l.google.com has address 74.125.19.147 www.l.google.com has address 74.125.19.99 www.l.google.com has address 74.125.19.103 www.l.google.com has address 74.125.19.104 www.l.google.com has address 74.125.19.105 Of course you could test that you can directly reach the Telstra DNS (using DNS) by this method. If explicitly doing a DNS lookup against those servers does work with say "host www.google.com 1.2.3.4" where 1.2.3.4 is the DNS server you are hoping to use, but plain "host www.google.com" doesn't then your DNS config is broken. > . > > So I entered the Bigpond dns servers for NSW, Queensland and Victoria > into network manager.
