I installed ssh and restarted it. Now 'ssh localhost' just says 'Connection closed by ::1 port 22.'

I get Permission Denied when trying to get hadoop binary. after research I found that I need to use sudo in front of command. So need to use
sudo wget http://mirrors.....
Thanks for great article!

In my case, the command:
sbin/start-dfs.sh
is executed without errors, but the NameNode is not started and therefore it is not responding on http://localhost:9870.
Executing jps command I can see how running processes are:
1) SecondaryNameNode
2) DataNode
3) Jps
NameNode process is missing from the returned list.
Any idea on what can be going wrong?
I followed all the instructions in this guide to configure my WSL environment.
Thanks
Have you tried the solution I mentioned in the post? I got the same issue when it is first installed but after the following commands, it work. And also make sure you stop and restart hadoop daemons.
sudo apt-get install ssh
sudo service ssh restart
I'm not expert in network and I don't think the following solution will definitely help as they are all local traffics. There must be some other reasons that you cannot ssh localhost. For example, is port 22 used by your other programs? Can you also use IPv4 addresses for localhost instead of the IPv6 one?
Can you try to add firewall rule to allow TCP traffic to ssh port 22?
