Cannot get on Internet

[nudge]

Where did the www go? I had FC-7 up and running fine on my machine. Connection to the internet required only the opening of Fire Fox. There was no special setting-up required. When I up-graded to F-10, I lost the Internet. My connection is through the motherboard Ethernet connector into the DSL modem and onto the phone line. No router or network. I have mucked around with the selections at: System>Preferences>Internet and Network, and System>Administration> Network without success. When I turn on the modem I get the “Connection Established” message at the network icon on the top right of the screen, but it's not really connected. The modem shows no traffic when I try to go to a web site. The machine is an older AMD Athlon XP2000 with an ESC motherboard and 750 Mb RAM.
I have spent several hours on this form and cannot find my solution. Any help would be appreciated.

are you usiing the correct Ethernet? do you have 1 or 2 Ethernet connections onboard?

Probably the infamous netmask == host IP problem...

There could be many reasons for that. For one try ping through telnet to your webserver and see if its working. You can also run these commands and check the IP and network interface data:
/sbin/ifconfig -a
and /bin/netstat -rn

run the following to learn more about each of them:
man ifconfig
man netstat

You may also like to look at /etc/resolv.conf. That file lists the nameservers that your machine points to for DNS services.

Would you post what "ifconfig eth0" run in a terminal says?

Only one Ethernet connection on board, the same one that worked with FC-7. I'll try the ping and the suggested commands. Many thanks for the help.

When I ping there appears to be a connection to the web. Also when I run the ifconfig and netstat commands it appears to be connected. Is this pointing to a Firefox problem? Thanks again.

maybe the internet is down? log a call and a tech will probably fix it and boot the internet server right back up again.....:-)

is DNS working? if you can ping but not browse maybe it cannot resolve....does nslookup www.google.com work?

[nudge]

I don't know what nslookup is. I have two machines, one with FC-7 that will access the internet, using it now. The second machine is the one with F-10 and it will not get on the net. I have looked at both machines /etc/host.conf and /etc/resolv.conf files and they are the same. Both have the same nameserver 192.168.1.254 called out. About now I'm in over my ears, I can get around the file system well, but I don't know what they do. I think i'll go back to FC-7 and hope F-11 fixes my problem. Thanks for all the help, it is good to know there are people out there that will lend a hand.

I don't know what nslookup is.

nslookup is a command that takes the string style internet host name like www.google.com,
asks a remote DNS server what the matching IP address is and returns it. It's more
common in Fedora to use the "host" or "dig" commands. If it were to fail it would probably help
diagnose your problem: either your gateway would be configured wrong.

My guess is your gateway is setup wrong, If you run

/sbin/route

It should show a row that starts with "default" and then value right after that should be the host that you connect to the internet:

Run /sbin/route in a terminal on the working F-7 host and compare the results to the same command on the F10 machine,
they should be the same if you're on the same network.

This is mine, the important info is in bold (my router/gateway is called gate.isp.net in this example)

$ /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 1 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default gate.isp.net 0.0.0.0 UG 0 0 0 eth0

I have tried the /sbin/route command with both machines. The only difference is the "1" in the flags column, Is this significant? I have also tried Konquer with no success. Is this a firewall problem? maybe I have firewall requirements so tight nothing will go through.

With F-7
[william@localhost ~]$ /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0

[william@localhost ~]$


With F-10 modem on:

[willam@localhost ~]$ /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 1 0 0 eth0
