这个错误是因为在虚拟网络 vmbr0 中建立了一个桥接,而在此过程中尝试设置 enp12s0 接口的 IP 地址。解决方法是在虚拟网络 vmbr0 中设置 IP 地址,而不是在 enp12s0 接口中设置。您可以按照以下步骤来解决此问题:
1. 打开 /etc/network/interfaces 文件。
2. 注释掉 enp12s0 接口的 IP 地址配置。
3. 添加以下内容到 interfaces 文件中:
auto vmbr0
iface vmbr0 inet static
address [IP 地址]
netmask [子网掩码]
gateway [默认网关]
bridge_ports enp12s0
bridge_stp off
bridge_fd 0
4. 将 [IP 地址] 替换为您希望设置的 IP 地址,[子网掩码] 替换为您的子网掩码,[默认网关] 替换为您的默认网关。
5. 保存并关闭文件。
6. 重启网络服务。
7. 验证 vmbr0 接口的 IP 地址是否已设置成功。

set 'enp60s0f0' (enp60s0f0) as default for IPv4 routing and DNS
To set "enp60s0f0" as the default for IPv4 routing and DNS in Linux, you can follow these steps:
1. Open the network configuration file for editing. The location of the file may vary depending on your Linux distribution, but it is commonly found at "/etc/network/interfaces" or "/etc/sysconfig/network-scripts/ifcfg-enp60s0f0".
For example, you can use the following command to open the file with the nano text editor:
```
sudo nano /etc/network/interfaces
```
2. Within the configuration file, locate the section for "enp60s0f0" or the corresponding network interface. It may look similar to this:
```
auto enp60s0f0
iface enp60s0f0 inet dhcp
```
3. Modify the configuration to set a static IP address and DNS server. Replace "dhcp" with "static", and add the desired IP address, netmask, gateway, and DNS server(s). For example:
```
auto enp60s0f0
iface enp60s0f0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8 8.8.4.4
```
Make sure to adjust the IP address, netmask, gateway, and DNS server(s) according to your network configuration.
4. Save the changes and exit the text editor.
5. Restart the networking service to apply the changes:
- For Ubuntu / Debian:
```
sudo systemctl restart networking
```
- For CentOS / Red Hat:
```
sudo systemctl restart network
```
Now, "enp60s0f0" should be set as the default interface for IPv4 routing and DNS. You can verify this by checking the output of the `ip route` command or by testing network connectivity.

这些警告信息通常表示在使用Scapy时没有找到指定接口的广播。这可能是因为指定的口名不正确或者该接口没有播地址。
要解决这个问题,你可以尝试以下方法:
1. 检接口名:确认你使用接口名是正确的。你可以`ifconfig`命令(在Linux系统)或`ipconfig`命令(Windows系统上)来查看系统中可用网络接口及其名称。
2. 使用默认网地址:如果你想发送广数据包,则可以使用默认网关的IP地址作为目标IP地址。你可以通过执行`route -n`命令(在Linux系统上)或`ipconfig /all`命令(在Windows系统上)来查找默认网关的IP地址。
3. 使用`scapy.route`设置默认接口:在Scapy中,你可以尝试使用`scapy.conf.route`设置默认接口和默认网关,如下所示:
```python
from scapy.all import *
conf.route.add(net="0.0.0.0", gw="默认网关IP地址")
```
请注意,上述方法可能因操作系统和网络配置而有所不同。确保以管理员权限运行脚本,并根据实际情况进行适当的调整。
