configure SSH on 3600 series router on GNS3

from global config mode

ip domain-name sourav.com

crypto key generate rsa

choose key modulus 1024 as anything less than that will not support ssh version 2,also naturally 1024 offers better security

username sourav password cisco

line vty 0 4

transport input ssh

login local 

privilege level 15

exit

ip ssh version 2

ip ssh authentication-retries 2

now you can see the version of the ssh configured on the router

by

do sh ip ssh

it should show

SSH Enabled - version 2.0

now try ssh from qemu host(linux microcore)

using the command 

ssh sourav@192.168.0.1(the ip will be different in your case)
