[root(0)@sys11 09:20:29 /home/work/Code_release/bj]# scp ./release.sh root@192.168.161.151:/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:
$ ps aux | grep ssh
# 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:
sudo apt-get install openssh-client
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.
to restart it type
sudo /etc/init.d/ssh restart
to stop it type
sudo /etc/init.d/ssh stop
to start it type
sudo /etc/init.d/ssh start
以下是主要的关键步骤：
OpenSSH server is part of Mac OS X and you don‘t need to install any additional package.
To enable the OpenSSH server of Mac OS X, open System Preferences:
Click on sharing and enable Remote Login:
This will start up OpenSSH server automatically.
直接关掉就保存了，因为mac是时时保存的。
