我正在尝试通过局域网从ssh到我的家庭路由器，以探索其内部。
shh myaccount@192.168.1.1
返回错误：
Unable to negotiate with 192.168.1.1 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1
要修复此问题，我使用-o选项ssh：
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 myaccount@192.168.1.1 -v
首先，ssh挂起大约5分钟，然后退出。
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 myaccount@192.168.1.1 -v

这是怎么回事？我没有看到任何错误消息。这是我第一次尝试通过SSH切换到家用路由器，因此可能根本不可能。 ssh-ing到家用路由器有什么经验？
