Probably the same problem as the person in #2505. Start up sshd with sudo /usr/sbin/sshd -d -p 2222 and connect with ssh localhost -p 2222 to see if that is the case.

[gulshanmudgal]

getting this.

hadoop@Gulshan:/home/gulshan$ sudo /usr/bin/sshd -d -p 2222
[sudo] password for hadoop:
debug1: sshd version OpenSSH_7.2, OpenSSL 1.0.2g  1 Mar 2016
...blah blah blah...
Missing privilege separation directory: /var/run/sshd

I don't think your sshd even started there, because you ended back at the command prompt. Per #2505 (message), in /etc/sshd/sshd_config make sure you have:

ListenAddress 0.0.0.0
UsePrivilageSeparation no          <--- that
PasswordAuthentication yes

Shut down the windows internal ssh server in services.msc.

Yes. That is a thing these days.
You cannot authenticate because you're connecting to the windows version of the sshd! Try eintering your windows password just for kicks.

Thanks to Both of You.
Finally got it working.

[ghost]

Can you tell me how you fix it finally? Thanks! @gulshanmudgal

[ghost]

After experiencing many failures, I finally succeeded！ @gulshanmudgal

See @issue 3173

[gobbedy]

@gulshanmudgal could you please share with others how you solved it?

UsePrivilageSeparation -> UsePrivilegeSeparation

[feinstein]

UsePrivilageSeparation is deprecated, any workarounds?

Yep, just create directroy "/var/run/sshd" or "/run/sshd" on sshd server, then it's working.
