step 1:configure the timezone
ln -sf /usr/share/zoneinfo/Asia/ChongQing /etc/localtime
install software of ntpdate
so use ntpdate then time is right
step 2:install tcpdump and ethtool
They r tools of capture the packages of the protocals,and r very useful for administrators
step 3:configure the route
There are two methods of changing the route
first,change the file of /etc/sysctl.conf ,in the file ,there is a option of net.ipv4.conf.default.forwarding and set it net.ipv4.conf.default.forwarding=off
second,echo "1" >/proc/sys/net/ipv4/in_forward
0 means shutdown
1 means up
step 4 :In order to increase the speed of network ,shutdown the service of ipv6.
step (1):lsmod the commadn of lsmod is used to check the status of ipv6
change the file of host
/etc/hosts
comment the all the option of ipv6
configure the NIC .because in the host there r two NIC ,so it must configure two ip for it .but how ,,,ifconfig,,,the answer is NO,WHAT???
look this :
configure the file of /etc/nework/interfaces
cp the file ,and delete the gw just configure the ip ,mask
