ssh：連接關閉IP後，SSH2_MSG_KEXINIT發送

我想從另一臺Linux機器ssh到我自己的筆記本電腦（Ubuntu 14.04）。我收到錯誤「Connection closed by IP」，其中IP是我的筆記本電腦的IP地址。下面是詳細的輸出（$HOME是主目錄）：ssh：連接關閉IP後，SSH2_MSG_KEXINIT發送

$ ssh [email protected]_IP -p 24 -vvv 
OpenSSH_6.6.1, OpenSSL 1.0.1e-fips 11 Feb 2013

debug3: load_hostkeys: loaded 0 keys

Connection closed by LAPTOP_IP

我不能在網上找到如何解決這個問題。當我嘗試在我自己的筆記本電腦上使用ssh localhost時，我得到了完全相同的調試輸出，但錯誤消息是Read from socket failed: Connection reset by peer。

即使在調試輸出中，有一行說Could not load "$HOME/.ssh/id_rsa" as a RSA1 public key，根據此answer，此消息是正常的。

這裏有一些關於我的設置一些額外的信息：

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

這個配置有什麼問題嗎？爲什麼會發生這種錯誤，爲什麼會在SSH2_MSG_KEXINIT sent之後發生？如何解決這個問題？

謝謝你真誠的！

做重新安裝SSH位

sudo易於得到--reinstall安裝openssh-server的openssh-客戶

爲什麼你認爲這將解決這個問題？ – zkytony

因爲我試過了，它對我很有用 –
