Internet Access problems in Fedora Core 4 1137

As Mark Smith pointed out, that's not quite right, the point of using the raw ip was to factor out DNS from the troubleshooting. From what I see in this post, either your gateway value isn't set right or your card's interface isn't setup right.

Ok, this is probably wrong, you want a nameserver entry as you do below: Usually when you get an ISP account, they'll tell you where their pop3 and smtp servers are, use that domain as one of the search entries, for example if your isp is foonet, suppose their pop3 is at pop3.foonet.com that's a hint the domain you'd want to add to search is foonet.com

search localdomain search foonet.com

the "nameserver" entry doesn't have to be there, it depends on your arrangement with the ISP

If you use dhcp, it's possible you won't have a nameserver entry in the resolv.conf file, in that case Linux is told each time by the isp where to go for dns. If you have a Linksys style hardware router proxy, usually it will do dhcp to the Isp and then you can either get addresses from it or you will use static addresses

I think it would be good to not buttume and check with the proxy to see what it's doing. When you say "proxy" do you mean a hardware style firewall-router-proxy like a Linksys or Netgear? Most of them have a web interface you can reach from the green side and turn off-on things like web caching, port forwarding and so on. The manual for it will tell you the the like

OK, I'm getting confused here, in your first post you said you had a 3com Etherlink XL 10-100 card implying you had just the one? So you really have two of these 3Com cards? If so things get more complex here, you'll want to check that linux using the right card. If you have two, maybe the card that's not plugged in is the one it's trying to use. This is especially likely because you just showed the output from interface eth1 and it shows a valid interface for 0.66

what does "ifconfig eth0" say? or even better just post to me what all these files contain:

etc-sysconfig-networketc-sysconfig-network-scripts-ifcfg-eth1

and what these commands say

ifconfig eth0 ifconfig eth1 netstat -nr netstat -i

Nope, not good, that means no packets ever got sent on eth1 ever. But the "UP" shows that the interface is UP

Yes, that's normal to ping to loopback, in fact the loopback will show as an interface if you type:

ifconfig lo or you will also see it mentioned from the output of netstat -i:

netstat -i (mine says:) Kernel Interface table eth0 1500 0 2406 0 0 0 2226 0 0 0 BMRU lo 16436 0 16 0 0 0 16 0 0 0 LRU

yeah, I'd say post that stuff (5 files and 4 commands) I requested above that should do it.
