无法 ping 两个 adhoc 无线 lop tops (linux)

Question

我想运行在两个顶部都具有 Linux OS 的 ad-hoc 无线。我用它来创建临时网络。（我已经在它之前停止了网络管理器）

sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode ad-hoc essid test-adhoc channel 3
sudo ifconfig wlan0 up
sudo ifconfig wlan0 192.168.1.1 netmask 255.255.255.0

我的 ifconfig:

和 iwconfig

vmnet8    no wireless extensions.

eth0      no wireless extensions.

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"test-adhoc"

          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

vmnet1    no wireless extensions.

第一个 Lop top 的 IP 是 <192.168.1.1>，第二个是 <192.168.1.2>。我检查了路线：

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
172.16.62.0     *               255.255.255.0   U     0      0        0 vmnet8
192.168.1.0     *               255.255.255.0   U     0      0        0 wlan0
192.168.237.0   *               255.255.255.0   U     0      0        0 vmnet1

但是当我从另一个 ping 一个时：

ping 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.

From 192.168.1.1 icmp_seq=5 Destination Host Unreachable
From 192.168.1.1 icmp_seq=6 Destination Host Unreachable

我该怎么办？我的系统是 Ubuntu 14.04.

Answer 1

我只是改变了我的方法。在此 tutorial 中，第二种方法无效。在第一种方法中，不要使用 "auto wlan0"。（如果这样做，您可能会连接到另一个网络）
