SSH Not Connecting

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:xxxxxxxxxxxxxxxxx/+xxxxxxxxxxxxxxxxxxxx.
Please contact your system administrator.
Add correct host key in $PATH to get rid of this message.
Offending ECDSA key in $PATH
ECDSA host key for 192.168.XXX.XXX has changed and you have requested strict checking.
Host key verification failed.

This means there is a deadlock here. This one is marked duplicate so no one can add answer
 and the one it links is marked off topic so no can add answer there as well. If you delete
the known_hosts, it will fix the issue as well.If you ever face this problem in SSH then you
need to put this command

$ ssh-keygen -R <host>
i.e. ssh-keygen -R 192.168.XXX.XXX

That's it.

File Sharing in Linuxmint

File sharing in Linux is quite easy if we follow the proper steps. Without taking time just follow the following steps. This steps is followed in Linuxmint but as possible you can use the same way in another distro as well.

First of all install the samba and its related packages. When you enter '*' on the end then it includes all related packages from the library.

$    sudo apt install samba*

Then enable samba in firewall

$    sudo ufw allow Samba

Create the client Id password

$    sudo useradd suman

$    sudo passwd Suman@123

When you add the user on your pc then it is for the local use. You need to provide the sharing password on shamba. It can be anything you wish. You just need to register desirable password and to to so  just Add Samba Sharing password using this command.

$    sudo smbpasswd -a suman

then enter the password for 'suman'.

> Now or any time just right click the folder you wish to share and click the sharing option.

> Switch on the option Share this folder.

>Now you can open the folder using smb://<IP address> in linux and \\<ipaddress> on windows.

Work is done. enjoy the sharing..
