ssh：连接关闭IP后，SSH2_MSG_KEXINIT发送

我想从另一台Linux机器ssh到我自己的笔记本电脑（Ubuntu 14.04）。我收到错误“Connection closed by IP”，其中IP是我的笔记本电脑的IP地址。下面是详细的输出（$HOME是主目录）：ssh：连接关闭IP后，SSH2_MSG_KEXINIT发送

$ ssh [email protected]_IP -p 24 -vvv

debug3: load_hostkeys: loaded 0 keys

我不能在网上找到如何解决这个问题。当我尝试在我自己的笔记本电脑上使用ssh localhost时，我得到了完全相同的调试输出，但错误消息是Read from socket failed: Connection reset by peer。

即使在调试输出中，有一行说Could not load "$HOME/.ssh/id_rsa" as a RSA1 public key，根据此answer，此消息是正常的。

这里有一些关于我的设置一些额外的信息：

OpenSSH的版本：SSH-2.0-OpenSSH_6.6.1p1 Ubuntu的2ubuntu2.8

的sshd_config：

Port 24 
AuthenticationMethods publickey 
# ListenAddress 192.168.1.1 
HostKey /etc/ssh/ssh_host_key 
ServerKeyBits 1024 
LoginGraceTime 600 
KeyRegenerationInterval 3600 
PermitRootLogin no 
IgnoreRhosts yes 
IgnoreUserKnownHosts no 
StrictModes yes 
X11Forwarding yes 
PrintMotd yes 
SyslogFacility AUTH 
LogLevel INFO 
RhostsAuthentication no 
RhostsRSAAuthentication no 
RSAAuthentication yes 
PasswordAuthentication yes 
PermitEmptyPasswords yes

这个配置有什么问题吗？为什么会发生这种错误，为什么会在SSH2_MSG_KEXINIT sent之后发生？如何解决这个问题？

谢谢你真诚的！
