"www.xxx.com could not be found"

[lesliek]

I'm keen to use FC3, but I'm being driven to conclude that it's not keen for me to use it.

I installed the version of FC3 which came with version 2.6.9-1.667 of the Linux kernel. The installation also included a version of the Firefox browser.

I was able to get to my ISP via a dial-up connection and to browse with the installed Firefox. Getting to my ISP involved my first getting a Linuxant modem driver specific to my kernel version.

At the same time as I was working all that out, I had a problem with my flash drive's not automounting.

I was told that that might be fixed by my updating my versions of hal and udev. I tried to update those, but hal would not update unless I updated my kernel as well, so I did that--to 2.6.10-1.770. At the same time as I updated the kernel, hal and udev, I took the opportunity to update to the latest version of Firefox (all of this updating being done with yum).

After that updating of the kernel, hal and udev, my flash drive automounted properly.

However, I had to update my Linuxant driver to accord with my new kernel version. I did that, satisfactorily as it seemed.

I then tried to dial up my ISP. I was able to connect. I then tried to use my updated Firefox browser. However, any url I tried to access was greeted by the title of this post and the further words, "Please check the name and try again".

I thought that perhaps the problem had arisen as a result of the updated Firefox, so I uninstalled it and re-installed my original version of Firefox from my installation cds. That makes no difference.

Where do I turn now? If anyone has any suggestions, I'd be grateful for them and I'd also be grateful if they were made keeping in mind that I'm a rank amateur at all this.

Can you "ping" an ipaddress out on the net somewhere???

Here is Google's IP address, try "ping 216.239.39.99".

If you can successfully ping that IP address, but you cannot reach it with "www.google.com" then your computer is not configured properly to do "name lookkups" via a "DNS" (domain name server) someplace out on the net. (typically you would get the DNS nameserver IP address from your ISP).

IF you cannot ping the IP address for Google, then you have a problem with either the IP address on your computer, the netmask on your computer, or the (default) Gateway for your computer.

Those would be my guesses. In any event, try the ping command and let us know what happened.

This happened to me too after an update.

"pinging" was working for me at this point

Go to Sytem Settings - Network
Double click on your network setting

(Actually I'm using Ethernet here so this may be somewhere else for a modem)

Anyway on this page that comes up for the network connection (wherever it is for you!)
Make sure the box is ticked which says
Automatically obtain DNS information from provider

I hope this is it

james_in_denver,

Thanks very much for your reply.

When I type "ping 216.239.39.99" and press Enter, I get "connect: Network is unreachable".

I gather that means that it's one of the other three things you mentioned, the IP address on my computer, the netmask on my computer, or the (default) Gateway for my computer. I'm not conscious that I've entered any particular information about those things, unless the business about the hosts file saying, "127.0.0.1 localhost.localdomain localhost" amounts to the IP address on my computer. (I have put that last bit in more than once in response to a warning that's come up during booting up about Gnome not working properly.)

If you are disposed to tell me how I test those three possibilities, I'd appreciate it very much.

However, one thing I can't restrain myself from saying (not that it does me any good) is that I just don't know enough to have tried to set up my Internet connection today (when it isn't working properly) any differently from the way in which I did it yesterday (when it did work properly). That's the thing that's so annoying!

In any event, I hope to hear from you again and thanks again for your post.

Leslie

PS It occurred to me that yesterday I was using yum satisfactorily and that it didn't involve the use of the browser, so I thought I'd see what it said when I tried it. I did "yum update tcsh" (just chose that at random). It didn't work. This is what it said:

"Setting up Update Process
Setting up Repos
http://mirror.pacific.net.au/linux/redhat/fedora/3/i386/os/repodata/repomd.xml:[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Trying other mirror"

Then it tried my second (and last) mirror with exactly the same result and ended:

"Cannot open/read repomd.xml file for repository: base
failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try."

I don't know whether that throws any more light on what's wrong.

Alan,

Thanks very much for your reply.

I found the area you're referring to and I think I'm ok so far as it's concerned.

I have a button selected beside text that says "Automatically obtain IP address settings with dialup". Then, beneath that, is a section called "DHCP settings". There's a spot in it for "Hostname", said to be "optional" and that spot is blank. Beneath that is a box saying "Automatically obtain DNS information from provider" and I have a tick beside that.

I'm willing to try any other suggestions, provided I can understand them!

Thanks again for taking the trouble to reply,

Leslie

Dialup?--have you tryed setting up KPPP yet?
It's under the RedHat (start if you wish)--Internet--KPPP

[james_in_denver]

okay can you post the results of the "/sbin/ifconfig" command??? (while your dialup connection is active).

It sounds like your I.P. address is not being set correctly when you connect.

Which tool are you using to make the dial-up connection, and can you post it's configuration file(s) so that somebody here (me?) can take a look at them?

[lesliek]

w5set,

Thanks very much for your reply.

Under "Application", "Internet", I have "Email", "Firefox Web Browser", "IM", "IRC", "Video Conferencing", but no "KPPP".

I ran "Add/Remove Packages" and looked in "Graphical Internet" and "Text-based Internet". I couldn't find any reference in either of them to "KPPP".

Perhaps I should be looking under some other heading in Add/Remove Packages, but I don't know which one.

Thanks again.

james_in_denver,

The results from ifconfig you suggested I post are as follows:

You aked which tool I am using to make the dial-up connection and whether I could post its configuration file(s).

I'm sorry, but I'm not sure I understand the first question. All that I am using, as far as I understand (which is obviously not very far!), is the "Network Device Control" program under "System Tools". If that's what you were asking, I don't know whereto find any of its configuration files.

I'd appreciate your elaborating on the two questions, so that I can post what you think might be useful.

Thanks again for your help.

Leslie

To those who have been trying to help me with my problem, thank you very much for taking the trouble. The problem is now solved. It arose from my misunderstanding of the meaning of one of the items in my network configuration, the one which invited me to say whether I wanted to "Make this connection the default route". I wrongly unticked that item. Once I ticked it, everything worked.

Thanks again and I apologise for taking people's time up unnecessarily.

[james_in_denver]

GLad you got it fixed :) , routing/"default gateway" was next on my list.

Happy Linuxing, and don't hesitate to check back if you run into any other problems!

James
