Linux下如何實(shí)現(xiàn)不同網(wǎng)段之間的訪問
本實(shí)例要說明的是:實(shí)現(xiàn)10.0.0.0/24網(wǎng)段與192.168.2.0/24網(wǎng)段相互訪問.
步驟1:查看本機(jī)IP地址
[root@localhost root]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:A7:6E:77
inet addr:10.0.0.120 Bcast:10.0.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2418 errors:0 dropped:0 overruns:0 frame:0
TX packets:1293 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:1000347 (976.9 Kb) TX bytes:192592 (188.0 Kb)
Interrupt:10 Base address:0x2024
步驟2:添加路由規(guī)則
[root@localhost root]# route add -net 192.168.2.0/24 eth0
步驟3:查看路由規(guī)則
[root@localhost root]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 * 255.255.255.0 U 0 0 0 eth0
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
注：route規(guī)則中，必須同時存在兩個網(wǎng)段，否則,一個網(wǎng)段的IP地址將無法訪問到另一網(wǎng)段的IP地址。
步驟4:檢測本地機(jī)(IP:10.0.0.120)與遠(yuǎn)程機(jī)(IP:192.168.2.80)是否可互訪.
[root@localhost root]# ping 192.168.2.80
PING 192.168.2.80 (192.168.2.80) 56(84) bytes of data.
64 bytes from 192.168.2.80: icmp_seq=1 ttl=127 time=5.51 ms
64 bytes from 192.168.2.80: icmp_seq=2 ttl=127 time=3.17 ms
步驟5:刪除路由規(guī)則
[root@localhost root]# route del -net 192.168.2.0/24 eth0
