如何登錄到遠程計算機

Question

我想從我的計算機登錄到遠程計算機，以便可以訪問nfs共享。 我使用以下命令：

ssh -l salini 192.168.164.78

但是現在我得到了：

Welcome to Ubuntu 14.04.4 LTS (GNU/Linux 4.2.0-34-generic x86_64)

Could not chdir to home directory /home/salini: No such file or directory
$ 

這是什么意思？ 我在具有IP的機器中：172.21.215.101

我要登錄到另一台IP地址為192.168.164.78且用戶名為salini的計算機

我該怎么做？

請幫我。 謝謝。

現在，我在調試中運行了“ ssh”。 這就是我得到的：

在分析ssh客戶端的詳細輸出之后，我們發現：

debug1: Connecting to 192.168.164.78 [192.168.164.78] port 22. debug1: Connection established.

已到達服務器（無網絡問題），並且您的ssh客戶端將在默認端口22上啟動連接。

debug1: Authenticating to 192.168.164.78:22 as 'salini'

您的客戶將嘗試驗證您為salini身份。它將通過可用的不同身份驗證方法（一個接一個）：

debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive

最后，他將要求您輸入密碼，因為他無法使用kerberos ， publickey對您進行身份驗證

debug1: Next authentication method: keyboard-interactive Password: debug1: Authentication succeeded (keyboard-interactive). Authenticated to 192.168.164.78 ([192.168.164.78]:22). 

您輸入了密碼，現在已連接到服務器

現在唯一的問題是您的$HOMEDIR由於某些原因而消失了...

Could not chdir to home directory /home/salini: No such file or directory
