对不起,如果这听起来多余,但相信我不是。 我已经尝试了几乎大部分与这个问题有关的链接,但到目前为止还没有任何工作。 我甚至试过这两篇文章。 以下是我到目前为止所尝试的
MindTerm home: /home/waqas/.mindterm/ SSH Server/Alias: 54.191.37.141 Connected to server running SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 Server's hostkey (ssh-rsa) fingerprint: openssh md5: 95:44:f1:40:07:90:00:2a:7d:9a:1f:49:a1:71:8a:0b bubblebabble: xilon-segen-tufep-manir-rekad-lucag-fetoz-sover-hyhuh-kafiz-kixox
在这个问题之前我做的最后一件事是2天前我试图在我的客户端上使用这个链接安装FTP服务器http://www.krizna.com/ubuntu/setup-ftp-server-on-ubuntu-14 -04-vsftpd / 。 不幸的是,这个链接并没有如预期的那样工作,我最终没有在FTPlogin成功。 而今天当我尝试login使用我的密钥对给我错误。
以下是我的ssh尝试的日志

尝试从known_hosts文件中删除密钥,然后重新尝试连接。
这至less应该删除任何“旧”caching的连接
我看到了一些改变FTP(SFTP)服务器设置链接中的OpenSSH和用户configuration的操作。 这些变化可能是你的问题的根源。
假设一个EBS支持的实例,你可以通过closures这个实例来解决这个问题(如果这个实例不是EIP的话,这将导致你的外部IP更改)。 然后分离根卷并将其作为非根卷附加到新的主机上,然后将其装入修复openssh或用户configuration。
可能的问题来源:您将login用户添加到ftpaccess组,或者将您的主用户设置为/ usr / sbin / nologin。
