Internet access problem

[R Page-Jones]

Hello

I have installed Ubantu 9.10 dual boot with XP

I am using a D-link router DSL-G624T with wired connection.

I have no internet problems with XP, but when booted into Ubuntu I
cannot access the internet.
I have a connection to the router.  (Putting 192.168.1.1 as a URL in
Firefox brings up the router page.)

I have tried editing the IP4 stettings to "manual". but I cannot
complete this action because I don't know what to put in to "Search
domains" box. So "apply" stays greyed out.

Any advice would be greatly appreciated.

Rob

Since you can connect to the router, your network interface obviously
has been assigned an IP address.
Does (on the command line)
ping -c 2 91.189.90.41
show replies while
ping -c 2 www.ubuntu.com
does not? If so, post the contents of /etc/resolv.conf.
The output of the command
route -n
might be useful too.

Since you probably didn't do any manual configuration on XP, there
should be no need for manual configuration in Ubuntu either.
But as an experiment you could enter something like foo.bar there (just
to enable you to apply the settings).
The setting of "Search domains" isn't exactly important but rather
something for convenience. Simplified explanation: if your machine wants
to find the IP address of a simple host name, like "myhost", and fails
it will append the value of "Search domains" to the host and try
again[1]. I. e. it would try to find an IP for myhost.foo.bar in this
example.

[1] The explanation isn't technically exact, just meant to provide an
idea for what "Search domains" is good for. If you're interested, take a
look at
man resolv.conf
which describes this technically accurate.

/etc/resolv.config was not recognised.so I have posted  the whole the
text from my pings:

Putting foo.bar in the domain search box didn't have any effect. The
"apply" button stayed greyed out. I must be doing something wrong here
but I can't see what!

Good, your router forwards packets sent by your machine to the internet
and vice versa.

Good. Name resolution seems to work too.
BTW: I was talking about www.ubuntu.com and not www.ubunti.com. And the
interesting thing is, I don't get ping replies from www.ubunti.com while
you do. Obviously your internet works even better than mine ;-)

> robin@robin-desktop:~$  /etc/resolv.config

It's /etc/resolv.conf, which is simply a text file. Opening it in a text
editor and pasting it's contents would be enough.

That also looks reasonable to me.

I was wondering about that but you sounded so sure. As I explained, the
search domain is not something which is not technically necessary to
make a network connection work. Therefore I see no reason why no
information in this field should cause the Apply button to stay greyed
out. What information did you not enter in this dialogue either?

Anyway, all the information you provided above seems to indicate that
your network connection is working perfectly well. So you should
probably explain what *exactly* you're talking about when you say "I
cannot access the internet". What exactly are you doing? What exactly is
the result of this action (error message, ...)?

I put in an ip address for the computer (192.168.1.6), the Netmask
(255.255.255.0), the gateway (192.168.1.1)
and the Primary DNS supplied by my ISP (212.135.1.36)

Looking at the desktop:
Mouse arrow on the small "connection" icon at top RHS of screen shows
"Wired network connection Auto eth0 active"
Clicking the Firefox icon brings up the Welcome to Ubunto 9.10 screen.
Clicking on any of the links has no effect.
Trying google  (top RHS)  with some word  has no effect.
Putting a known URL in the Firefox address has no effect.

Your help much appreciated.

Hm, for me, the apply button gets enabled after entering just IP and
netmask.

What does "no effect" exactly mean? Does even the little circular
spinner not show any activity?
What does happen if you type something like
http://www.google.com
in the URL bar and wait for a couple of minutes? Firefox should
eventually display some message if it can't retrieve the desired web page.

Some other things you could check:
Did you configure Firefox to use a proxy / is the system configured to
use a proxy that might not be available?
If you have another browser installed on the machine: does the same
happen with it too?
What does (on the command line)
wget http://www.google.com
show?
If you click refresh in update-manager, does it work or do you get any
errors?

As an experiment I put an xubuntu 9.40 live CD into my computer. The
program came up OK and connected to the internet without any problems. I
checked out a few web addresses and navigated round the web a bit to
check out the operation. All was OK.. (xubantu  8.04 also accesses the
internet without any problem.)

As a newcomer my object is to get some experience of linux and I am
inclined to install a version like this one which I know works OK. That
way I can find out more about the basics such as using the command line.

Once again my thanks for all the help.

Not even remotely good. You should never see a public name
resolved to the address 1.0.0.0 (hm, and I thought we had name
resolution already eliminated from the list of possible problems).
Please show the output of (on the command line)
cat /etc/hosts
and
cat /etc/resolv.conf

Hm, interesting. gb.archive.ubuntu.com is resolved to a correct
address. Although it doesn't help you much since you've probably have no
IPv6 connectivity. What does
host gb.archive.ubuntu.com
show?
If you go to
System/Administration/Software Sources
an change "Download from:" to "Main server", does "check" in update
manager work better?

Which confirms that it's a configuration problem.
Did your network access ever work on this Ubuntu install?

I DO have IPv6 connectivity, and I DON'T get IPv6 coming back from

I meant to add that you can turn IPv6 resolution off in wget with the
"-4" or "--inet4-only" option, or just prefer IPv4 using
"--prefer-family=IPv4".

That's because Google uses separate names for it's IPv6 enabled services
- at least if you've not taken additional measures to make the "normal"
Google names to resolve to IPv6 addresses:
http://www.google.com/intl/en/ipv6/

But Rob's case is different. For him, update manager wants to connect to
the IPv6 address gb.archive.ubuntu.com resolves to.
OTOH, for him www.google.com resolved to 1.0.0.0. And that's bad.

Hello,

I solved the no sound problem.  Or, I discovered the source of it.
The mute mode was checked.  Without audio output the wireless
speakers' transmitter goes into the off mode (and no light).

I came across the above solution after there was a major upgrade.
It is possible that before the upgrade the sound was not working.

When I insert the CD rom and run 9.10 from live cd rom, it is still not
possible to access the internet.

Looks like what is to be expected, too.
And doesn't explain why www.google.com resolves to 1.0.0.0.

Then I'm out of ideas.

Just a last shot in the dark: since update manager tries to connect to
an IPv6 address - do you see any improvement if you disable IPv6?
You could add
ipv6.disable=1
to the boot options.
Easier, and maybe something worth trying first, is disabling IPv6 only
for Firefox: Type
about:config
in the URL bar and press return, accept the warning, and type ipv6 in
the filter bar. You should see the
network.dns.disableIPv6
entry. Double click it to change it's value tor true.
Does that cause any improvement?

That hasn't worked in some time (see the list archives). Perhaps it does
now, but System|Help|Internet and Networks / Troubleshooting seems to
provide a way that might:

<quote>
5.2.7. IPv6 Not Supported

   1. IPv6 is supported by default in Ubuntu and can sometimes cause
problems.
   2. To disable it, open a Terminal (Applications ▸ Accessories ▸
Terminal) and type the command: gksudo gedit /etc/modprobe.d/aliases.
   3. Find the line alias net-pf-10 ipv6 and change it to read alias
net-pf-10 off.
   4. Reboot Ubuntu.

When I enter the command line:

gksudo gedit /etc/modprobe.d/aliases
An empty box comes up with "aliases (/etc/modprobe.d) - gedit" as a title across the top, but the box itself is completely empty.

Seems that the documentation is _way_ outdated... BTW: that was from
both Jaunty (9.04) and Karmic (9.10) help docs.

Did you do what I suggested to disable IPv6 for Firefox? If so, does it
improve things?

As mention previously, to disable IPv6 add
ipv6.disable=1
to the boot options. To do that
gksudo gedit /etc/default/grub
search for the line containing GRUB_CMDLINE_LINUX_DEFAULT, which should
look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
change it to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"
Save the file, quit gedit and do
sudo update-grub
and reboot.

Eureka!  I did the changes exactly as you said and on the next boot  the
internet was working OK. I checked it out by surfing a few web sites and
all is well.

Once again many thanks.
