to internet. Please tell me how do I configure manually to give my IP,
gateways and DNS adresseses now.
1. /etc/sysconfig/network
This file contains information about your hostname, and default gateway
i.e.
[dmz /var/log/samba]# cat /etc/sysconfig/network
NETWORKING=yes
CHOSTNAME=hostname.domain.com
GATEWAY=192.168.0.1
FORWARD_IPV4=no
GATEWAYDEV=eth1
2. /etc/resolv.conf
This file contains information regarding your dns server settings.
i.e.
[dmz /var/log/samba]# cat /etc/resolv.conf
search domain.com
nameserver 192.168.0.4
nameserver 216.254.141.2
3. /etc/sysconfig/network-scripts/ifcfg-eth0
This file contains information regarding your ip address settings.
i.e.
[dmz /var/log/samba]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
NOZEROCONF=yes
BROADCAST=192.168.0.255
HWADDR=00:0B:DB:90:85:92
IPADDR=192.168.0.5
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes
TYPE=Ethernet
4. If you make any changes to the ifcfg-eth0 file you will need to issue
the command
/etc/init.d/network restart
5. In order to manually set the ip address of a network card you can
alternatively issue the command....
[user@machine]# ifconfig eth0 192.168.0.5 up
6. In order to view the current status of your network settings you can
use the commands ifconfig, route, ping, host
i.e.
[user@machine]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0B:DB:90:85:92
inet addr:192.168.0.5 Bcast:192.168.0.255 Mask:255.255.255.0
