反向 SSH“连接被 ::1 关闭”

反向 SSH“连接被 ::1 关闭”

我尝试建立远程 ssh 连接。

我尝试连接“远程”ssh -fN -R 10110:localhost:22 GatewayUser@GatewayHost

和“网关”ssh -p10110 RemoteUser@localhost

我在网关控制台上收到了响应Connection closed by ::1

使用 -v 运行它ssh -v -fN -R 10110:localhost:22 GatewayUser@GatewayHost

在远程控制台中生成该响应

debug1: client_input_global_request: rtype [email protected] want_reply 1
debug1: client_input_channel_open: ctype forwarded-tcpip rchan 2 win 2097152 max 32768

debug1: client_input_global_request: rtype [email protected] want_reply 1

PS：从远程到网关的 SSH 连接正在工作

提前谢谢了！

答案1

您要做的是：创建一个从 raspi 到网关的 ssh 连接，并将 *:10110 从网关转发到 raspi 上的 127.0.0.1:22。然后连接到端口 10110@localhost，在某些配置中该端口可能使用 ip6 地址 (::1)，其后面没有隧道。然后 sshd 关闭连接。尝试

ssh -4 -p10110 pi@localhost

这应该会让你更进一步。如果您在查找正确的密钥时遇到问题（ssh 在检查一定数量的密钥后停止），则禁用 pubkeyauth

ssh -oPubkeyAuthentication=no -4 -p10110 pi@localhost

答案2

您的ssh客户端似乎sshd通过 IPv6 连接到您的。是否sshd监听 IPv6 地址？添加此行/etc/ssh/sshd_config并重新启动sshd：

ListenAddress ::

或者您可以使用ssh -4参数强制 IPv4 连接。
