Need help Badly

[alice06]

Hi all

I am a Ph.D physics student and have started programing in C language in Ubuntu 8.04.
But when I am in Ubuntu, my web browsers show 'Page load error, Address not found' page.

Actually it all started after my brother started downloading a lot of movies from the net.
In Windows it is all fine but I have to do my programing in Ubuntu and need a lot of help from the web,
thus I am badly stuck with the web browsers not working.

Please help me, I have a lot of work but can't do anything. Please help somebody.

Alice

That error usually means that your DNS settings are incorrect. Please post the contents of /etc/resolv.conf here.

Thanks Rubberman for replying

as u asked, the /etc/resolv.cnf has

# Generated by NetworkManager
nameserver 192.168.1.1

I must also inform u that I am working on ubuntu 8.04 and some sites, like gmail etc that are working but there are many many other sites (like even this one) which are not working and showing page load error.
But everything is working in windows.

Is it some setting problem in firefox ??

Please help

The name server is set to your local router. You need to see what the DNS server your router is using in turn. You can modify your DNS servers on your machine to go outside your local router. I have experienced similar problems to your own when my ISP's DNS servers were having problems. It still happens occasionally, in which case I reorder the DNS settings in my /etc/resolv.conf file to point to two well known top-level internet DNS servers. See what happens when you edit your /etc/resolv.conf to this (you don't have to reboot):

nameserver 199.45.32.37
nameserver 199.45.32.40
nameserver 192.168.1.1

The first two servers are for Bell Atlantic and are two of the main internet DNS servers.

You may need to restart your browser after editing /etc/resolv.conf.

Hi Rubberman

I edited /etc/resolv.conf to

nameserver 199.45.32.37
nameserver 199.45.32.40
nameserver 192.168.1.1

But then even even those pages which were opening, did'nt open.

Just to inform you, this is the internet information for my windows ( where everything is working)

ip address- 192.168.1.5
subnet mask-255.255.255.0
default gateway-192.168.1.1
preffered dns server202.159.219.229
alternate dns server202.159.217.198

Then use the windows DNS server addresses ( 202.159.219.229 and 202.159.217.198 ) in place of the first two entries I showed for /etc/resolv.conf.

In Ubuntu, you may need to enter the DNS settings through the Network Manager applet as it may overwrite your changes; it should be on the panel somewhere at the top right.

These instructions are for Ubuntu 10.04 and the process may vary slightly in 8.04

Right click on it and select "Edit Connections"
It will pop up a window, choose Wired or Wireless as apporopriate
Select the connection and click edit
Select IPV4 settings
If you are using DHCP then select DHCP Addresses only and enter your DNS servers in the test box (separated by a comma).
Then go to IPV6 settings and set the method to ignore.
Click Apply and then OK your way back to the desktop.
You will be asked for password at some point during this process.

And they say a GUI is easier

If that still doesn't work, we will try disabling IPV6 in Firefox.

Open a new tab and navigate to about:config (acknowledge any warnings)
Enter ipv6 in the text box and you should see an entry called network.dns.disableIPv6
Double click it to set it to false.
You may need to restart firefox

Disable IPV6 the command line way

Thank u rubberman and elija. Thank u for being concerned for me.

But I reinstalled a newer version of firefox yesterday and since then things are working great. Haven't had any problems after that.

If I have problems again, I will get back to u.

Thanks a lot. This forum is great.
