<big>Resisted. continuing. Ubuntu issues w/router persist.<br>
<br>
Lost count of troubleshooting exercises.<br>
<br>
Recap: At 7:30 am all was OK and that during a session on a website via
the Linux box, the internet access to that site went down.<br>
This leads be to believe that the configuration of the Linux box was
correct. <br>
<br>
Dlink router: downloaded and installed latest firmware. Reset
configuration to factory defaults.<br>
Windows box: internet access continues to be OK.<br>
Linux box: Previously configured to dial through DSL modem to ISP.<br>
Linux box: Now does the same through router.<br>
ifconfig now shows IP 209.183.xxx.yyy not 192.168.0.100 as before (at
7:30 to 11:30 am)<br>
<br>
Linux box Changed Settings > Network > Options > wired not DSL
<br>
Rebooted. NADDA ifconfig now shows IP 209.183.xxx.yyy not 192.168.0.100
as before.<br>
<br>
Linux box: ping 127.0.0.1 OK<br>
Linux box: ping localhost OK *<br>
* sometimes fails (not sure what I was doing when I saw the failure)<br>
<br>
Router: moving wires between physical ports. NO WIRELESS.<br>
<br>
I am shutting everything down for a cold boot boot later this evening
and will pick up on this at that time.<br>
<br>
Thanks<br>

Thanks for the tip: was looking for something like this.<br>
<a moz-do-not-send="true"
href="http://etherealmind.com/what-is-the-best-ip-address-to-ping-to-test-my-internet-connection/">http://etherealmind.com/what-is-the-best-ip-address-to-ping-to-test-my-internet-connection/</a><br>
<br>
Troubleshooting round four:<br>
Pings with named ping destinations fail on both the Linux and Windows
boxes.<br>
e.g. c:\>ping <a moz-do-not-send="true"
class="moz-txt-link-freetext" href="https://www.google.ca">https://www.google.ca</a>
c:\>ping
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.google.ca">http://www.google.ca</a><br>
<br>
One of the destinations recommended in the link above, ping 8.8.8.8
works on the Windows box.<br>
The Linux box however is still failing. <br>
<br>
On the Linux box, the error message returned for ping 8.8.8.8 is
different from ping <a moz-do-not-send="true"
class="moz-txt-link-freetext" href="http://www.google.ca">http://www.google.ca</a>.<br>
For the google.ca, I see "unknown host".<br>
For 8.8.8.8 I see: from 192.168.0.1 icmp_ .... Destination Net
Unreachable.<br>
<br>
Looks like the router is blocking the Linux box.<br>
Rebooted router. NADDA.<br>
<br>
Troubleshooting round five:<br>
<br>
Bypassed the Dlink router. Connected Linux box direct to DSL modem.<br>
Setup Ubuntu > Settings > Network as req'd to dial on the DSL
modem as opposed to wired connection.<br>
<br>
FF on Linux box works.<br>
<br>
The issue with the Dlink router not the Linux box per se.<br>
Disconnected the Linux box, reconnected router and Windows box.<br>
<br>
OT (slightly):<br>
How do I set up Ubuntu with more than Network connection configuration?<br>
1) (default) wired connection through router (w/o 'dialer' settings)<br>
2) DSL modem with 'dialer' settings<br>
<br>
Thanks<br>

<pre wrap="">Can you ping a site on the internet from clients? eg 4.2.2.2
If not, you have no connectivity to the internet. Check
cables/routing/gateway config.
If so, can you ping a site by name: google.ca
If not, check DNS.

<pre wrap="">Ubuntu 12.04 LTS localhost* and internet fail (w/FF)- where to start?
My Linux box is, all of a sudden, failing to connect to the internet.
I was on a site earlier when the site (and others) started returning
the FF "server not found" (404) message.
Actually, I have made, I think, a good start (see below).
I am asking where do I go now?
Troubleshooting round one:
Boot. Reboot. Ubuntu restart. etc.
re-wired Linux box to Router connections.
Troubleshooting round two:
Linux box > terminal > ping 192.168.0.1 (Dlink router) are OK
Linux box > terminal > ping 192.168.0.115 (Windows box) OK
Linux box > terminal > ping 192.168.0.101 (loop back to Linux box) OK
Linux box > terminal > ping localhost (loop back to Linux box via
LAMP) OK *
Windows box > cmd window > ping 192.168.0.1 (Dlink router) are OK
Windows box > cmd window > ping 192.168.0.101 (Linux box) are OK
Windows box > cmd window > ping 192.168.0.115 (loop back Windows box)
are OK
Windows box > cmd window > ping localhost (loop back to Windows box
via XAMPP) are OK
*ping localhost was failing on the Linux box when I started
troubleshooting. Working now.
FF internet access still fails.
Troubleshooting round three:
Suspecting that the issue may be isolated to FF:
FF restarted in safe-mode. i.e. with add-ons disabled: still fails
Attempted bypass of FF through Ubuntu Software Centre and install of
Chromium browser: fail.
Analysis: The issue does not look to be isolated to FF.
Thanks
JohnJ
