我一直在尝试安装edX,其命令行指令之一是
cat /etc/hosts
我收到的回复是
cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 precise64
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
广播ip丢失了,为什么会这样?
答案 0 :(得分:1)
您通常不会在/ etc / hosts文件中列出广播地址。你为什么期望在那里看到它?
什么是'edX'呢?有自己的README文件的URL?
想想看,如果你真的需要主机的广播掩码,你就是 最好使用ifconfig的变体。以下是一些例子:
(Solaris 11.x)
enter code here
$ ipadm show-addrprop -p broadcast e1000g0/v4
ADDROBJ PROPERTY PERM CURRENT PERSISTENT DEFAULT POSSIBLE
e1000g0/v4 broadcast r- 192.168.1.255 -- 192.168.1.255 --
limoncello:jmcp $ ifconfig e1000g0
e1000g0: flags=100001100943<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,ROUTER,IPv4,PHYSRUNNING> mtu 1500 index 2
inet 192.168.1.20 netmask ffffff00 broadcast 192.168.1.255
或者,在linux上(Debian Jessie):
jmcp@debiant:~$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:cd:61:7c
inet addr:192.168.1.249 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::a00:27ff:fecd:617c/64 Scope:Link
inet6 addr: 2001:44b8:2188:f000:a00:27ff:fecd:617c/64 Scope:Global
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:1000
RX bytes:44119 (43.0 KiB) TX bytes:29635 (28.9 KiB)
在Solaris主机上,我感兴趣的接口的广播地址是192.168.1.255;在Debian vm上,它是一样的。
