fedora 14禁止IPV6

fedora 14是默认开启IPV6的。

所以用ifconfig会产生下面的内容

 

  eth0    Link encap:Ethernet  HWaddr 00:0C:29:13:22:E0
          inet addr:192.168.30.187  Bcast:192.168.30.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe13:22e0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:52 errors:0 dropped:0 overruns:0 frame:0
          TX packets:60 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:6420 (6.2 KiB)  TX bytes:6931 (6.7 KiB)
          Interrupt:19 Base address:0x2000

如果要去掉对IPV6的支持

需要在系统中添加文件 /etc/modprobe.d/blacklist-ipv6.conf

文件内容
install ipv6 /bin/true
blacklist ipv6

 

然后重启系统：

命令ifconfig的输出是

 

  eth0    Link encap:Ethernet  HWaddr 00:0C:29:13:22:E0
          inet addr:192.168.30.187  Bcast:192.168.30.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:52 errors:0 dropped:0 overruns:0 frame:0
          TX packets:60 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:6420 (6.2 KiB)  TX bytes:6931 (6.7 KiB)
          Interrupt:19 Base address:0x2000
