SSH在远程PC在同一网络 - 权限被拒绝（公钥） [英] ssh to remote pc in the same network - Permission denied (publickey)

问题描述

我试图在远程服务器上安装git，这些是该pc的详细信息

  IP 192.168.1.7 
 Ubuntu版本12.04 32位
  

我安装了两个openssh，并且ssh的状态为这

  ssh启动/运行，进程756 
  

我试图从本地电脑ssh到那台电脑，这些是我本地的详细信息

  IP 192.168.1.4 
 Ubuntu版本12.04 64位
  

我有ping到192.168.1.7

  rashendra @ rashendra：〜$ ping 192.168.1.7 
 PING 192.168.1.7（192.168。 1.7）56（84）字节的数据。

来自192.168.1.7的64字节：icmp_req = 2 ttl = 64 time = 1.02 ms 
从192.168开始的64字节.1.7：icmp_req = 3 ttl = 64时间= 3.78毫秒

 rtt min / avg / max / mdev = 0.918 / 1.908 / 3.782 / 1.326 ms 
  

<这意味着我可以连接到那台电脑，并且连接是活着的。

我已经生成了存储在 /home/rashendra/.ssh

  rashendra @ rashendra：〜/ .ssh $ ll 
 
 total 20 
 drwxrwxrwx 2 rashendra rashendra 4096 Nov 17 11:37 ./ 
 drwxr-xr-x 47 rashendra rashendra 4096 Nov 17 08:35 ../ 
 -rw ------- 1 rashendra rashendra 1679 Nov 17 10:57 id_rsa 
 -rwxrwxrwx 1 rashendra rashendra 401 Nov 17 10:57 id_rsa.pub * 
 -rw-r  -  r -  1 rashendra rashendra 444 Nov 17 11:45 known_hosts 
  

之后，我将 id_rsa.pub 的内容复制到 authorized_keys 在远程PC的 .ssh 中



  cat /tmp/id_rsa.pub>> 〜/ .ssh / authorized_keys 
  

这是 .ssh 我创建的git用户。

所以，现在我试图用



  ssh git@192.168.1.7 
  

还有以下错误：

  rashendra @ rashendra：〜/ .ssh $ ssh git@192.168.1.7 
 
权限被拒绝（publickey）。 
  

请咨询如何解决。
因为我需要在这个远程服务器上安装git并进一步维护。


解决方案

检查您的权限：

• （ chmod 644〜/ .ssh / id_rsa.pub ）



• 在服务器端

    chmod 700 /home/git/.ssh 
   chmod 600 /home/git/.ssh/authorized_keys 
     
   
   
    b $ b 
   
   
  在客户端， ssh -Tvvv git@192.168.1.7  
   
   
  在服务器端，一个调试ssh守护进程会话（ / usr / sbin / sshd -d ）：参见这个答案。
   
   
   
  I am trying to install git on a remote server and these are the details of that pc
  IP 192.168.1.7 
  Ubuntu version 12.04 32 bit 
  and I have install both openssh and the status of the ssh is this 
  ssh start/running, process 756
  And I am trying to ssh to that pc from local pc and these are the details of my local
  IP 192.168.1.4
  Ubuntu version 12.04 64 bit
  I have ping to the 192.168.1.7 
  rashendra@rashendra:~$ ping 192.168.1.7
  PING 192.168.1.7 (192.168.1.7) 56(84) bytes of data.

  rtt min/avg/max/mdev = 0.918/1.908/3.782/1.326 ms
  which means I can connect to that pc , and the connectivity is alive.
  
  I have generate the rsa public/private key which are stored in the /home/rashendra/.ssh 
  rashendra@rashendra:~/.ssh$ ll
  
  total 20
  drwxrwxrwx  2 rashendra rashendra 4096 Nov 17 11:37 ./
  drwxr-xr-x 47 rashendra rashendra 4096 Nov 17 08:35 ../
  -rw-------  1 rashendra rashendra 1679 Nov 17 10:57 id_rsa
  -rwxrwxrwx  1 rashendra rashendra  401 Nov 17 10:57 id_rsa.pub*
  -rw-r--r--  1 rashendra rashendra  444 Nov 17 11:45 known_hosts
  After that I copied the content of the id_rsa.pub to the authorized_keys in the .ssh of the remote pc
  cat /tmp/id_rsa.pub >> ~/.ssh/authorized_keys
  This is the .ssh of the git user which I created.
  
  So, now I am trying to connect to the remote pc using 
  ssh git@192.168.1.7 
  yet gives the following error:
  rashendra@rashendra:~/.ssh$ ssh git@192.168.1.7
  
  Permission denied (publickey).
  Please advice how to resolve.
  As I need to install git on this remote server and maintain further.
  解决方案
  Check your permissions:
  
  
  on the client side (chmod 644 ~/.ssh/id_rsa.pub)
  on the server side
  chmod 700 /home/git/.ssh
  chmod 600 /home/git/.ssh/authorized_keys
  
  
  
  Then, if it is still not working, check the output of:
  
  
  on the client side, a ssh -Tvvv git@192.168.1.7
  on the server side, a debug ssh daemon session (/usr/sbin/sshd -d): see this answer.
