ssh 到同一网络中的远程电脑 - 权限被拒绝(公钥) [英] ssh to remote pc in the same network - Permission denied (publickey)

问题描述

我正在尝试在远程服务器上安装 git，这些是那台电脑的详细信息

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 

而且我已经安装了 openssh 并且 ssh 的状态是这个

and I have install both openssh and the status of the ssh is this

ssh start/running, process 756

我正在尝试从本地电脑 ssh 到那台电脑，这些是我本地的详细信息

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

我可以 ping 到 192.168.1.7

I have ping to the 192.168.1.7

rashendra@rashendra:~$ ping 192.168.1.7

这意味着我可以连接到那台电脑，并且连接是有效的.

which means I can connect to that pc , and the connectivity is alive.

我已经生成了存储在 /home/rashendra/.ssh 中的 rsa 公钥/私钥

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

之后我将id_rsa.pub的内容复制到远程电脑的.ssh中的authorized_keys

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

这是我创建的 git 用户的 .ssh.
所以，现在我正在尝试使用

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 

但出现以下错误:

rashendra@rashendra:~/.ssh$ ssh git@192.168.1.7

Permission denied (publickey).

请指教如何解决.因为我需要在这个远程服务器上安装 git 并进一步维护.

Please advice how to resolve. As I need to install git on this remote server and maintain further.

推荐答案

检查 您的权限:

• 在客户端(chmod 644 ~/.ssh/id_rsa.pub)

• 在服务器端

chmod 700 /home/git/.ssh
chmod 600 /home/git/.ssh/authorized_keys

然后，如果还是不行，检查输出:

Then, if it is still not working, check the output of:

• 在客户端，一个 ssh -Tvvv git@192.168.1.7
• 在服务器端，调试 ssh 守护进程会话 (/usr/sbin/sshd -d):参见 这个答案.

• 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.
