with your gateway IP )
NETWORKING=yes
HOSTNAME="plain.ev1servers.net"
GATEWAY="XXX.XXX.XXX.XXX"
GATEWAYDEV="eth0"
FORWARD_IPV4="yes"
2. Modify /etc/hosts (
replace YYY.YYY.YYY.YYY with server ip)
replace server1.company.com with your server name.
replace server1 with your first part of your desired hostname.
127.0.0.1 localhost.localdomain localhost
YYY.YYY.YYY.YYY server1.company.com server1
3. restart kernel logging services
/etc/rc.d/init.d/syslog restart
