Trouble connecting pi 3 via SSH using putty

[sayan101pi]

I am a beginner with the raspberry pi. I am using the raspberry pi 3 . I am having problem connecting it to my laptop.
i have enabled the SSH connection from the raspberry terminal . But now when i am trying to establish connection using putty it is showing an error message "Network Error: Software caused connection abort.". I can't figure out what the problem is .
Please Help!

Thanks in advance!

from the raspberry terminal window try
ifconfig to find the ip of your RPI
wlan0 Link encap:Ethernet HWaddr b8:27:eb:0d:ea:33
inet addr:192.168.1.203 Bcast:192.168.1.255 Mask:255.255.255.0
hostname

on the ?win? PC cmd window now try
ping -a 192.168.1.203 should tell you same as hostname
arp -a 192.168.1.203 should tell you same HWaddr (MAC)

how is the connection? both are connected to same router?

Kindly ensure that you have enabled ssh from:-

raspi-config -> "Advanced Options" -> "SSH" and enabled it.

Hope this may help !

The SSH connection is enabled.
Still not working.

[sayan101pi]

The connection is fine. I am getting reply after pinging .
both are connected to the same router.

Software caused connection abort.

all i tested here gives only time out or connection refused
but not your error msg.
can you try with a fresh burned RASPBIAN SD ( with the (empty) ssh file for first boot )

I tried with afresh burned SD , now its showing connection refused error. But that is because the SSH is disabled by default in the latest Raspbian Jessie .

[sayan101pi]

Is there any other way of enabling the SSH without using any external display ???

[KLL]

yes, as i write above,
SD back in card reader, open /boot/ in ?windows? create file named ssh
back in RPI and ssh will be enabled ( and file deleted )

[sayan101pi]

yes, as i write above,
SD back in card reader, open /boot/ in ?windows? create file named ssh
back in RPI and ssh will be enabled ( and file deleted )

What kind of file ?
A text file ?

[KLL]

if a text file would be ssh.txt it would be wrong,
name must be ssh
it can be empty.

[sayan101pi]

Now its giving network time out error.

[KLL]

check IP again /ping arp
check putty settings :IP, port: 22, type: SSH
test with a other ethernet cable RPI--router

[sayan101pi]

I did . I am getting reply after pinging .
The connection is alright i guess.

[KLL]

if i use win7 cmd ping -a ...
i get "pinging RPI3" ( you must get raspberrypi ) the host name set by sudo raspi-config

if the IP in putty is wrong i get time out,

unless i use the IP of a connected PC,
then get connection refused, same if the RPI IP is right but SSH port is wrong.

[sayan101pi]

These are my pinging stats.

But now i am again getting connection refused error message.

Run this command from a terminal window on your pi:

Code: Select all

nano /etc/ssh/sshd_config

3rd - 4th line down should read '# What ports, IPs and protocols we listen for' - what does the line below that say?

OP already used a new RASPBIAN setup ( and "ssh" file for enable )
so it should not be a RPI settings problem, i work headless from the beginning.

but i see something ( what i not understand )
the ping -a shows a very strange device name
instead of "raspberrypi" it says "raspberrypi.mshome.net"
there might be a difficult network setting possibly with disable ssh port settings? firewall ? ( am i right, it did never work b4 ?)

if network setup is not in your hand i can only recommend
to connect RPI with ethernet cable to laptop ( and laptop online with wifi )
( also not easy setup but we can talk you through )

raspberrypi.mshome.net and the ip-addresses in 192.168.137.x are easily explained.
Internet Connection Sharing is being used on the PC, this implements a mini-dhcp using 192.168.137.x and the domain mshome.net.

Putty does [should] work with this configuration using the ip-address, I have done this a few times already.

but that would mean that the RPI is NOT connected to the router, instead to the laptop ethernet port?

The connection is fine. I am getting reply after pinging .
both are connected to the same router.

anyhow in both cases SSH should work, unless the PC has a firewall blocking 22?

Nothing will surprise me, I have seen it all and I have even done it myself.
Without proper cable management and labeling it is a simple act to plug the wrong cable into the wrong socket. My favorite trick is to put the keyboard USB plug into the RJ45 socket on a notebook and then scratch my head why my keyboard is not working.
