EC2 实例不响应内部 ping
我编写了一个脚本，启动多个具有相同安全组（默认安全组）的亚马逊实例，允许 ICMP 和所有 TCP/UDP 连接...所以没有防火墙问题。 我正在运行 ubuntu 11.4 64 位 ami，工作正常。
通常在一堆机器中我启动一些不响应任何 ping 或 telnet 连接。他们可以 ping 通其他机器，但无法 ping 通。其他机器可以在两个方向上相互 ping 通，没有任何问题，但通常只有一两台机器不响应任何 ping。我启动它们的方式没有区别，所以我不明白这个错误来自哪里......
如何避免这个问题并在不重新启动EC2实例的情况下从中恢复？
非常感谢温柔的开发者：D。
I did a script that launch several amazon instances with the same security group which is the default one, with ICMP and all the TCP/UDP connection allowed... so no firewall problem.
I am running an ubuntu 11.4 64 bits ami working fine.
Usually in the bunch of machine I launch some do not respond to any ping or telnet connection. They can ping other machines but cannot be pinged. The other machines can ping each other in two directions without any problem, but usually one or two just don't respond to any ping. There is no difference in the way I launch them, so I don't understand where this bug comes from...
How to avoid this problem and recover from it without restarting the EC2 instance?
Thanks a lot tender developpers :D.

尝试
安全组。创建一个新规则：
try this
security group.Create a new rule:
假设您启动的所有实例都具有相同的安全组和相同的 ami，您需要联系亚马逊了解此事。

Assuming all the instances you launch have the same security group and same ami, you need to contact amazon about this.
