Ping 地址显示请求超时

Ping 地址显示请求超时

我完全是 Linux 新手,尝试通过 SSH 从 OS X 远程登录 Debian。

在服务器上安装 OpenSSH 后,ssh -vvv ***.***.***.165给出以下输出:

debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *
debug1: /etc/ssh_config line 102: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to ***.***.***.165 [***.***.***.165] port 22.
ssh: connect to host address port 22: Operation timed out

然后我尝试ping address给予:

PING ***.***.***.165 (***.***.***.165): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
.
.
.
--- address ping statistics ---
134 packets transmitted, 0 packets received, 100.0% packet loss

/sbin/iptables -L我已经检查了服务器上的输出:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination   

任何评论都将受到赞赏。

编辑: /sbin/ifconfig输出:

抱歉,我必须屏蔽 IP,并且***.***.***上述内容代表同一件事。

更新:

将本地计算机连接到其他 Wifi 后,我成功进行了 SSH。有许多 PC(包括服务器)通过同一路由器(有线或无线)连接到互联网。我的本地计算机是通过无线连接的。一旦我将 Wifi 切换到另一个,SSH 就可以正常工作。

如果我想恢复原来的Wifi,该如何解决问题?
