xshell连接需要公钥【已解决】

这是一个小问题，但是不得其门而入就会很累。
解决连接问题 首先要想到的是/etc/ssh/sshd_config目录；
至于免密互连则是 ~/.ssh目录

我解决就是将其他机器的/etc/ssh/sshd_config的sshd_config给copy过来了

具体配置文件如下
·
1 HostKey /etc/ssh/ssh_host_rsa_key
2 #HostKey /etc/ssh/ssh_host_dsa_key
3 HostKey /etc/ssh/ssh_host_ecdsa_key
4 HostKey /etc/ssh/ssh_host_ed25519_key
6 SyslogFacility AUTHPRIV
7 # but this is overridden so installations will only check .ssh/authorized_keys
8 AuthorizedKeysFile .ssh/authorized_keys
9 #PermitEmptyPasswords no
10 PasswordAuthentication yes
11 #ChallengeResponseAuthentication yes
12 ChallengeResponseAuthentication no
13 # GSSAPI options
14 GSSAPIAuthentication yes
15 GSSAPICleanupCredentials no
16 # problems.

18 #GatewayPorts no
19 X11Forwarding yes
20 #ShowPatchLevel no
