我试图通过客户端提供给我的用户名和密码SFTP到服务器，但我一直Disconnected: No supported authentication methods available (server sent: publickey) 。 我在Ubuntu 13.10上，我试过在terminal上使用Filezilla gui以及sftp -vv user@host和lftp -u user sftp://host 。
以下是我在debugging中从Filezilla获得的输出：详细模式：
Response: fzSftp started Trace: CSftpControlSocket::ConnectParseResponse(fzSftp started) Trace: CSftpControlSocket::SendNextCommand() Trace: CSftpControlSocket::ConnectSend() Command: open "user@host" 22 Trace: Server version: SSH-2.0-CoreFTP-0.3.1 Trace: Using SSH protocol version 2 Trace: We claim version: SSH-2.0-PuTTY_Local:_Sep_14_2013_01:12:43 Trace: Using Diffie-Hellman with standard group "group14" Trace: Doing Diffie-Hellman key exchange with hash SHA-1 Trace: Host key fingerprint is: Trace: ssh-rsa 1024 b1:ac:c5:b6:d2:b8:d3:ef:fc:d2:b3:d8:06:2c:d2:25 Trace: Initialised AES-256 SDCTR client->server encryption Trace: Initialised HMAC-SHA1 client->server MAC algorithm Trace: Initialised AES-256 SDCTR server->client encryption Trace: Initialised HMAC-SHA1 server->client MAC algorithm Trace: Pageant is running.

sftp -vv输出类似。 看起来，Pageant在密码之前提供了我的公钥（这是正常的），但是却没有继续进行密码validation。 有没有一种方法来强制密码authentication（即绕过所有的网页）？ 我必须能够通过此连接bash脚本操作，所以使用sftp或lftp命令将是必要的。 有一个标志，我可以设置来完成这个？ 我查看了手册页，但没有find我正在寻找的东西。
在客户端的服务器上总会有错误configuration的机会，但由于客户端能够从这个帐户login没有问题，我怀疑这个问题是在我的身边。
UPDATE
客户端能够使用Windows上的Filezilla使用此帐户login服务器，排除其服务器configuration为只允许公共密钥validation的可能性。 这是一个IT部门的大公司，有很多这样的账户，所以假设他们以前做过这样的事情是相当安全的。 这里是他们debugging的输出：Verbose in Filezilla：

服务器被configuration为只允许公钥authentication，而不是密码。 你可以在这里看到：
Trace: Disconnected: No supported authentication methods available (server sent: publickey) Error: Disconnected: No supported authentication methods available (server sent: publickey)
