scp出现ssh port 22: Connection refused 问题解决具体步骤

Posted 2020-10-04 再见理想

[root(0)@sys11 09:20:29 /home/work/Code_release/bj]# scp ./release.sh  [email protected]:/Users/a2014102/Downloads
ssh: connect to host 192.168.161.151 port 22: Connection refused
lost connection

 

 

Solution: 
One possible reason is that because the ssh server daemon, or sshd, is not loaded and running on localhost, so any attempt to ssh connect to localhost would fail. I check to see whether ssh and sshd are running by typing the following command:

 

 

1. $ ps aux | grep ssh  

2. # Result: bunch of lines, but none of them is about "sshd", only one line is about "ssh"  

 

Result is, I only see ssh running, but not sshd. So I know ssh server daemon is probably not started yet.

First, I verify that I have installed the package “openssh-server” on my fedora box.

Then I check the status of sshd service:

 

You may not have OpenSSH completely installed. Type this in terminal:

 

 

1. sudo apt-get install openssh-client  

2. sudo apt-get install openssh-server  

 

Another problem that you could have is that your firewall could be blocking the ssh connection. I use Firewall Configuration to manage my ports and firewall.
