无法通过 SSH 连接到我的桌面

我正在尝试从我的 Mac 笔记本电脑 ssh 到我的 Linux 桌面。

我ifconfig在我的 Linux 桌面（目标机器）上运行并获取了 eth0 下列出的 IP 地址（机器通过有线连接 - 而不是无线连接）旁边的“inet addr:”

我在我的 Mac 上用这个 IP 地址执行 ping 命令，效果如预期一样好。

但是当我尝试使用相同的地址通过 ssh 连接到该机器时，我无法访问该机器：

$ ssh -A 172.28.11.243
ssh: connect to host 172.28.11.243 port 22: Connection refused

我已经在 Google 上搜索了下下一步要检查的内容，但不清楚该怎么做。如能提供任何建议，我将不胜感激。

更新1：

$service ssh status
ssh stop/waiting

更新 2：

$ps -eaf | grep sshd
rabdelaz 23832  8389  0 10:53 pts/1    00:00:00 grep sshd

从头开始：

答案1

好的，由于某种原因，您的ssh服务无法启动。日志中应该有一些信息，请尝试

sudo grep -i ssh /var/log/*log

然后发布输出，我们看一下。

不过，我猜只需重新安装ssh服务器即可解决问题。如果您不介意丢失对ssh配置所做的任何更改，请尝试以下操作：

sudo apt-get purge openssh-server ssh
sudo apt-get install openssh-server ssh
sudo service ssh start

然后尝试从另一台机器再次登录。
