第五章 FreeBSD之配置网络服务

一、查看网络适配器名称

root@svros:~ # ifconfig 
 
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=81009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,VLAN_HWFILTER>
        ether 00:0c:29:33:c5:90
        inet 192.168.107.128 netmask 0xffffff00 broadcast 192.168.107.255
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

二、配置DHCP

# sysrc ifconfig_em0="DHCP"

或者

# vi /etc/rc.conf
 
hostname="svros.com"
ifconfig_em0="DHCP"  //设置动态获取ip
local_unbound_enable="YES"
sshd_enable="YES"
moused_enable="YES"
ntpdate_enable="YES"
ntpd_enable="YES"
powerd_enable="YES"
dumpdev="AUTO"

三、配置静态IP

sysrc ifconfig_em0="inet 192.168.107.128/24" defaultrouter="192.168.107.2"

或者

#vi /etc/rc.conf
 
hostname="server1.example.com"
ifconfig_em0="inet 10.10.10.100 netmask 255.255.255.0"  //设置ip地址和子网掩码
defaultrouter="10.10.10.1"   //设置默认网关
dumpdev="AUTO"

四、配置DNS

# vi /etc/resolv.conf
 
# nameserver 192.168.253.2
nameserver 114.114.114.114         
nameserver 127.0.0.1
options edns0

五、重启网络

# service netif restart
 
# service routing restart

或者

# sh /etc/rc     //刷新系统设置
 
# /etc/netstart  //重启网络

六、测试网络连通性

# ping baidu.com
