无法 ping 本地主机

我无法 ping 本地主机

  ashish@ashishk:~$ ping localhost
    PING localhost (127.0.0.1) 56(84) bytes of data.
    ^C
    --- localhost ping statistics ---
    16 packets transmitted, 0 received, 100% packet loss, time 15003ms

这是我的主机文件：

ashish@ashishk:~/chef-repo/.chef$ cat /etc/hosts
127.0.0.1   localhost
115.112.95.170    ashishk.example.com chef

# 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

答案1

得到解决方案：

ashish@ashishk:~/chef-repo/.chef$ vim /etc/sysctl.conf

# Ignore Directed pings
net.ipv4.icmp_echo_ignore_all = 1

设为 0 就可以了
