Linux Kali - 互联网已连接，但没有 VPN 或 Tor 就无法工作

我找不到这个问题的答案，也无法自己解决。我是三次启动 Ubuntu/Kali/Windows 11。互联网在 Ubuntu 和 Windows 上运行完全正常，但当涉及到 Kali Linux 时，即使连接了 wifi，我也无法使用互联网。

该命令ping -c3 8.8.8.8成功运行，但当我 ping 一个网站（例如 google.com）时，它返回ping: www.google.com: Name or service not known.当我打开 VPN 或使用 Tor 浏览器时，可以访问互联网。但是如果我只使用firefox，它就无法连接

当我打开VPN时，我可以ping通www.google.com，否则我不能。

我的/etc/resolv.conf文件：

nameserver 8.8.8.8

当我运行命令（以 root 身份）时：for t in filter nat mangle raw security; do echo "Table '$t'" ; iptables -t "$t" -nvL 2>/dev/null; echo; done.我得到：

当我运行命令时grep hosts /etc/nsswitch.conf，我得到：

hosts:          files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns myhostname

答案1

运行该命令grep hosts /etc/nsswitch.conf会给出以下条目：

hosts:  files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns myhostname

外表[!UNAVAIL=return]可疑；它表示如果热门名称/地址查找服务不可用，则返回。但不幸的是，这是在使用 DNS 查找之前。

小心地尝试删除它，所以该行变为如下：

hosts:  files mdns4_minimal [NOTFOUND=return] dns
