首先,我知道这个问题已被问过一百万次了,我已经阅读了我能找到的所有内容,但仍无法解决问题.
我正在遇到这个问题,当我从我的mac ssh进入我的ubuntu服务器上全新安装的Ubuntu(因为这个问题我重新安装).
我有SSH端口映射到7070,因为我的ISP阻止了22.
在客户端：
- bash: ssh -p 7070 -v me@address.org
- debug1: Reading configuration data /etc/ssh_config
- debug1: Connecting to address.org port 7070.
- debug1: Connection established.
- debug1: identity file /home/me/.ssh/identity type -1
- debug1: identity file /home/me/.ssh/id_rsa type 1
- debug1: identity file /home/me/.ssh/id_dsa type -1
- ssh_exchange_identification: Connection closed by remote host
确保我的maxstartups没问题：
- bash: grep MaxStartups /etc/ssh/sshd_config
- #MaxStartups 10:30:60
>确保hosts.deny没有否认.
>确保hosts.allow拥有我的客户端IP.
>清除客户端上的known_hosts
>将/ var / run的所有权更改为root
>确保etc / run / ssh是
>确保/ var / empty存在
>重新安装openssh-server
>重新安装ubuntu
当我运行telnet localhost时,我得到了这个：
- telnet localhost
- Trying ::1...
- Trying 127.0.0.1...
- telnet: Unable to connect to remote host: Connection refused
当我运行/usr/sbin / sshd -t时
- Could not load host key: /etc/ssh/ssh_host_rsa_key
- Could not load host key: /etc/ssh/ssh_host_dsa_key
当我重新生成密钥时
- ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
- ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
我犯了同样的错误.
我很确定这是问题所在.有人可以帮忙吗？
