UNIX for Dummies Questions & Answers

I have a installed Redhat Linux v5 on a new HP Pavillon PC. It has a dual boot with Vista. Booting from Vista, I can connect to the internet. However with Redhat I cannot connect to the internet.

I looked at the /etc/resolv.conf file in Redhat and there is no DNS entry there. From where do I get the DNS entry from and what is the format that I enter the DNS entry in resolv.conf.

An example of resolv.conf file will help.

Looking forward for your help.

Get the nameservers from your isp or use DHCP.

Here are samples of the relevant files to check.

resolv.conf

Code:

nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx

/etc/sysconfig/network

Code:

NETWORKING=yes
HOSTNAME=Somehostname
GATEWAY=192.168.1.1    #What ever your gateway is.

/etc/sysconfig/network-scripts/ifcfg-eth0

Code:

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.100.255
IPADDR=192.168.1.190
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes

Ikon,

Thanks so much for your suggestions.

For resolv.conf file you suggested that I get the nameserver from my ISP. I have tried that and was not able to obtain it. Since I have Vista installed on the same PC, could I do cmd>ipconfig /all on DOS and get the DNS server number like 192.xxx.xx.xx and use the same number for Redhat.

Also for ifcfg-eth0, do I use exactly the same numbers for Broadcast, IPADDR etc as yours?

To connect to an ISP, you will (typically) use DHCP with your ethernet interface. Ikon has given you an example of a static IP, which might work if you copy down all the information from the vista configuration (from ipconfig /all after you have a connection). However, that might not work because the IP address you get might be released when you shut down, letting the ISP assign someone else that IP address.

Anyway, what you really want to do is set up the interface to use DHCP, and for that, you can just use the RedHat management tools to set up networking. If you don't want to run X, RedHat has a command-line tool, but the name of it escapes me at the moment.

I changed the resolv.conf, /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network files as per Ikon's suggestions but could get the internet connections.

Any other suggestions!!! Think we need an updated driver or something.

Will look forward for your help.

As repeatedly suggested, set it up to use DHCP instead. That's almost 100% certainly how Vista does it, unless you have configured it by hand to do something else.

Of course, it might also be a good idea to check that eth0 is working in the first place. Can you ping your router? Do you get notices about eth0 and/or TCP and/or Ethernet in /var/log/dmesg when you boot?

Era,

Yes, it is set up for DHCP.

There is a radio button checked in Devices -- Automatically obtain IP address settings: DHCP

In the network configuration window it has:

Device eth0: Status Inactive, Nickname:eth0, Type: Ethernet
Hardware: Type Ethernet, Device: eth0, Status:OK
IPSEC: There are no entries
DNS: Hostname--HP-a6512p-b. For Primary, Secondary and Tertiary DNS, I found values from VISTA using IPCONFIG /ALL and entered them for DNS.
HOSTS: There are no entries

Is there anything I am missing? Is it possible to talk to someone. I will call.

Thanks and Regards,

Anil
