Error In Bringing Up the Interface Eth1 RTNETLINK Files.

[Rafaeel]

I am using the Linux operating system since long time but don't have any idea what is the exact problem with it is because since one week the problems of the Linux have been started. I had also tried to Trouble shoot with the help of the Google but in vain. I have also two NIC cards In my Computer. And was using the first one which did not had any problems. It worked for me but then the similar problem arises again and I cannot use by browser due to this problem. Please tell me a solution as this problem is causing me a lot of frustration in to me.

Actually the above information that you have given is insufficient and would love to have some more important information and it would be more helpful for solving the problem of yours. How was the first NIC can be made quit. And of what type the NIC is their and how it is embedded or card and also what about the link media. You were also saying that you are able to ping from outside, what about errors listed from the output of 'ifconfig -a' from both the kind of machines. What kind of error messages are shown when your logging of your remote drives. And also about the LAN? Does your router switch off or your hub work properly or not.

I have a distro is CentOS 5.3. And using the box as a web server. My NIC is embedded and there has been no problem with the physical connection as I am able to connect to this machine remotely. I can also access the other machines using their ip address from this machine but not with their domain name having in them . When I do the following in this machine this is the results:

First:
# /etc/rc.d/init.d/network restart
Shutting down interface eth1: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth1: RTNETLINK answers: File exists
Error adding address (ip) for eth1.
[ OK ]
Second:
$ ping
ping: unknown host
Third:
#vi /etc/resolv.conf
# Generated by NetworkManager
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

In the third case when I put the name servers manually and restart the network the same results comes.

The details tell me that something has gone duff in the system which can be resolved by doing the resolve.config option. When you cannot do the name resolution but your able to ping all such kind of stuffs. Or your facing a routing issue. If your using a static IP address it should be set to the cards or do you use DHCP. This should help you out with the basic dealing of the browsing issues.

It is sounding like you are having a DNS problem. You can also try a third level DNSl ike Verizon's;

example '/etc/resolv.conf';

search 192.168.1.1 #local

nameserver xxx.xxx.xxx.xxx #ISP DSN

nameserver 4.2.2.1 #Verizon third level DNS
nameserver 4.2.2.2
nameserver 4.2.2.3
nameserver 4.2.2.4

But for this you should have to use your ISP DNS.

You can also try by doing the below steps:
Bringing up interface eth1: RTNETLINK answers: File exists
Error adding address (ip) for eth1.
And this is the type of my resolution.

• After you have done the #setup you set name server then saved. And do #service network restart.
• Now do #vi /etc/resolv.conf you will never see any name server here.

And the reason behind it I don't know

• So when you go to do the #setup you set name server then saved.
• You don't need to do the #service network restart.

#ping
In the ping you got to type the following site name.
