在虚拟盒中运行的 Windows 主机和 Centos 之间的 ssh 访问拒绝访问

在虚拟盒中运行的 Windows 主机和 Centos 之间的 ssh 访问拒绝访问

我尝试使用 GUI 关闭防火墙 system-config-firewall。
此外，还关闭了 SELinux。
但我无法使用 Windows 7 主机连接到虚拟机中的客户 CentOS。我可以 ping 客户操作系统。我重新安装了 sshd，并尝试在不同的端口 (5562) 上运行它，但输入正确密码后总是出现“访问被拒绝”的情况。

附加详细信息：
我已将客户操作系统配置为静态 IP 10.0.2.10。
此外，virtualbox 主机专用网络的 IP 地址设置为 192.168.56.1

如果我尝试ssh localhost在客户操作系统上操作，它可以正常工作。
此外，尝试从其他运行 CentOS 的机器通过 ssh 连接到客户操作系统。它也会出现权限被拒绝错误。

另外，尝试在 guestOS 上运行 wireshark，当主机操作系统出现访问被拒绝错误时，它不会在端口 22 上收到任何请求。

netstat -l --numeric_ports | grep 22

正确显示

tcp  0 0 *:22 *:* LISTEN

# This is the sshd server system-wide configuration file.  See

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a

答案1


在虚拟机上配置网络适配器时，您有多种选择：默认是NAT，所以如果你什么都不做，那么你只需要在网络选项选项卡（网络--->适配器--->高级）中执行端口转发。请查看这个 StackOverflow 问题

答案2

在虚拟盒中，需要启用连接到仅主机适配器的适配器 2，并使用第二个适配器 (eth1) 提供的 IP 地址进行 ssh 连接。

以下链接中有详细解释： http://wiredrevolution.com/virtualbox/setup-ssh-access-between-virtualbox-host-and-guest-vms

适配器 1（连接到：NAT）和 eth0 应保留原样用于互联网。我错误地尝试通过 eth0 访问互联网和 ssh。
