SSH server closes connections

Whenever I attempt co connect to my Pi3's ssh server, I get "Connection closed by <ip> port 22".
This is on a fresh Raspbian Jessie 11-25 install.
Attached is the output from
http://pastebin.com/Q5GfNAbZ
I tried
on the pi with similar results.
Thanks in advance!

SSH is now disabled by default in all present and future Raspbian OS releases.
Use the RPi configuration tool in [menu] --> [Preferences] or sudo raspi-config to enable SSH.

Ssh has been enabled, as evidenced by the fact that the log shows that a connection was established and the remote protocol version was given.

Yes, they "fixed" it so it doesn't work at all. Raspi-config, either command line or GUI is no help and putting in the /boot/ssh file per their blog does no good...so it is very safe indeed...you just can't use it. I think I still have the previous iso on another drive...will get it back and get rid of this garbage until the masters of the piniverse fix it so it can be used.
Edit:
After my previous tantrum, I went back and looked for my old version of jessie/pixel but I had already deleted it...so back to work. Not quite sure what fixed it but I am now able to login by ssh to this RPi. I did two things. First, I used the old linux/unix standby command "passwd" to enter a new password.
I also logged in with
with the new password. With that giving a happy result, I logged in using ssh on another RPi and then back to this one with the new password and all went well. I reiterate that the configuration utilities, either cli or GUI were useless to fixing this problem.
No apologies to the maintainers...to screw up a previously useable access without serious debugging/workarounds on a computer that is supposedly aimed at children and others with little experience...well, what can I say. This is a cluster-****.

Not sure what your issue is?
I tried all 3 enableing methods and they all work for me.

SSH is enabled, that's not the problem. The port is identified in the log and by telnet as an SSH server

It works perfectly for me by putting the "ssh" file into /boot. If it's not working for you then something is wrong on your end. Bad SD card? Bad imaging procedure? Not correctly creating the ssh file (having known file extension on Windows set to hidden, so that you don't see that the file you actually created is ssh.txt)?

After enabling of course I tested each case by connecting to the RPi using PuTTY from a Windows 10 computer.
I conneceted using IP address which I have reserved in my routers DHCP reservations table.

Loss of connection after "SSH2_MSG_KEXINIT sent" may be because the host keys are missing or corrupt. Try regenerating:
Code: Select all
sudo rm /etc/ssh/ssh_host_*
sudo dpkg-reconfigure openssh-server
Also, check for errors in /var/log/auth.log.

This worked for me. Thanks!

I don't have my LCD working. And I need the ssh to fix my LCD .I mean I'm completely headless. The ssh file didn't work for me and raspberry closes the connection automatically. is there any way for me to try this solution?

The best way to get help is to start a fresh thread.
Describe your actual problem as it is now.
Are you really running Raspbian Jessie? Lots of things have changed since the original post in 2016, and the original poster has not been active in the forum since March 2017
