SSH connection problem to the vSphere ESXi Host

Hi,

Sometimes, When we tried to make a connection with SSH, we can see below error.

Server unexpectedly closed network connection

Perform the following steps to resolve this error:

We login to our ESXi host as local shell.

# chmod 600 /etc/ssh/ssh_host_rsa_key

Need to restart ssh service after run the above command.

We run the following command to restart the process.

# ./sbin/services.sh restart

Then seamlessly we can connect SSH.

Regards.
