How to check hostname and IP bindings in RH Linux 6.2?

[JulianChappell]

Hello,

I want to check what hostname and IP address is bound to my Linux server's ethernet card. Can anyone tell me how to do this? Please talk to me like I'm a niddiot, because my Linux and Networking knowledge is a little weak. I'm only doing this because Oracle support told me to.

TIA,

Julian

Hi,

On redhat, the hostname is set in the file /etc/sysconfig/network as the parameter 'HOSTNAME=' . To display that file use the cat command :

$ cat /etc/sysconfig/network

Similarly, the IP address details for the first ethernet card are stored in the file /etc/sysconfig/network-scripts/ifcfg-eth0 , although if it has 'BOOTPROTO=dhcp' then the interface would dynamically get an address via dhcp when the network was started.

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

The above are the static entries used to configure the system at startup. To view the actual active settings, including addresses set via dhcp, you'd do :

$ /sbin/ifconfig eth0

or even

$ /sbin/ifconfig (for all interfaces)

Hope this helps
