ssh_config中

Protocol 1,2ListenAddress 127.0.0.1HostKey ./ssh_host_keyHostKey ./ssh_host_rsa_keyHostKey ./ssh_host_dsa_keyRSAAuthentication yesPubkeyAuthentication yes

解决方法 我只是遇到了同样的问题,通过将我的相对HostKey路径转换为绝对路径来解决它,即代替

HostKey ./ssh_host_key

放：

HostKey /home/dmitry/ssh_host_key

或者无论在哪里.

这个错误不是很有帮助吗？
