Why the sshd service is unrecognized?

Question

I'm trying to install hadoop, and I need to restart the sshd service in order to configure the connection between the nodes... However, whenever I write: service sshd restart a message error will be displayed telling me that this service is not recognized.

Any help to install this system?

Answer 1

In Ubuntu, install sshd client and server with these commands:

sudo apt-get install openssh-client

and

sudo apt-get install openssh-server

Then, to restart sshd, type:

sudo /etc/init.d/ssh restart

This worked for me, when I had the same problem. You can find more information here.

Answer 2

Try these commands:

For Debian/Ubuntu

/etc/init.d/sshd restart

For RedHat and Fedora Core Linux

/sbin/service sshd restart
