Hi,

I have a Linux box connected to a Linksys router connected to ADSL modem.
Firefox can not display any web pages from the web (or from the router). For example, if trying to go to redhat.com, The bottom status line says “connecting to redhat.com. After a few minutes, a message, “The operation timed out when attempting to connect to redhat.com, come up. A similar message is displayed when trying to connect to the router (192.168.1.1).

The Linux box get its ip address from the router. ifconfig shows an ip address.
The Linux box can ping the router and a Windows box connected to the router.
The Windows box can ping the Linux box. The Windows box can access the web.

During the install, the firewall was disabled. Entered 'service iptables stop' too (that disables the firewall?). Network proxy config is “Direct internet connection”. The last line from route is: default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

When trying to ping redhat.com, it reports address 209.132.177.50 but has 100% packet loss.

Any suggestions?
Thanks

You went through a lot of troubleshooting, but you left out one little thing. You mention trying to ping redhat.com with 100% loss. Did you try pinging it's IP address? What % success or loss do you get with that?

What is the contents of your /etc/resolv.conf? That file should have your list of DNS server IP addresses. If all it has is a line like

search NETWORK

and nothing else try replacing it with the IP address of a DNS server

nameserver xxx.xxx.xxx.xxx

Keep in mind since you're getting your information from your router this file will be overwritten each time.

Thanks for your reply.

A ping to 209.132.177.50 results in 100% packet loss.

etc/resolve.conf has 2 addresses in it and they are the same as in the Windows box.
Pinging the ISP is OK. Entering the IPS URL into Firefox results in the operation timed out message. (Entering garbage into the URL results in,"... could not be found. Please check the name and try again".)
