如何修复 OpenWRT 故障安全模式 SSH 端口 22: Connection refused

English Deutsch 简体中文

问题：

你正在尝试使用 SSH 通过 ssh 192.168.1.1 连接到故障安全模式下的 OpenWRT 路由器，但你看到此错误消息：

output.txt
ssh: connect to host 192.168.1.1 port 22: Connection refused

解决方案

首先，检查你是否有正确的 IP 配置：

Ping 192.168.1.1 以验证你的 IP 配置：

ping.sh
ping 192.168.1.1

示例输出：

ping_output.txt
uli@uli-computer:~$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=63 time=1.20 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=63 time=1.35 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=63 time=1.14 ms

然后，尝试再次使用 SSH 连接：

ssh_connect.sh
ssh [email protected]

如果你仍然得到

output.txt
ssh: connect to host 192.168.1.1 port 22: Connection refused

你运行的是旧版 OpenWRT。故障安全模式下的 SSH 仅从 OpenWRT 15.05 开始支持。对于旧版本，使用 telnet 连接：

telnet.sh
telnet 192.168.1.1

你应该看到 root shell：

telnet_output.txt
elnet 192.168.1.1
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.

 === IMPORTANT ============================
    Use 'passwd' to set your login password
    this will disable telnet and enable SSH
