将一台并行计算机与另一台并行计算机进行 ping

将一台并行计算机与另一台并行计算机进行 ping

我已将两个并行网络适配器分配给桥接网络。

控制机 10.171.102.162 主机 10.171.102.161

我无法从控制端 ping 或 ssh 到主机，这两个主机都是 ubuntu 的并行实例

日志

parallels@parallels-vm:~$ ansible -m ping all
10.251.55.13 | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: ssh: connect to host 10.251.55.13 port 22: Connection refused\r\n", 
    "unreachable": true
}
parallels@parallels-vm:~$ ^C
parallels@parallels-vm:~$ ping ^C

从控制机进行 ifconfig

parallels@parallels-vm:~$ ifconfig
