Ping 可以工作，但 wget、curl 和 apt 不行...请禁用防火墙以确保问题不在这里

因此，正如消息中所说，目前根本没有运行防火墙，但 curl/wget 不起作用，而 ping 起作用（此外，我通过 SSH 连接到机器，apache2 可以工作，因此它可以在端口 80 上接收请求）。这是一个古老的谜团！以下是一些希望有用的信息...

我确信这不是防火墙问题（防火墙已完全禁用）

我的 /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
auto lo inet loopback

# The primary network interface
#auto eno2
#iface eno2 inet static

auto eno1
iface eno1 inet manual
bond-master bond0

auto eno2
iface eno2 inet manual
bond-master bond0
bond-primary eno2

auto bond0
iface bond0 inet static
bond-mode active-backup
bond-miimon 100
bond-slaves none

重启网络失败

systemctl restart networking.service
Job for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.

这是我得到的错误

更新

感谢@JohnRonald，我更新了 iface 行并成功重新启动网络，但并没有解决 curl/wget 问题。

这是 curl 错误@raj

有任何想法吗？

这是我的运行配置：

自动 eno1
iface eno1 inet 手动
bond-master bond0

自动 eno2
iface eno2 inet 手动
bond-master bond0

自动 bond0
iface bond0 inet 手动
bond-模式 4
bond-miimon 100
bond-xmit_hash_policy layer3+4
bond-lacp-rate 1
bond-从属 eno1 eno2
