Setting permissions to 700 worked for me on redhat 7.

A very handy method for debugging ssh is here on stackoverflow:

https://unix.stackexchange.com/questions/156038/ssh-server-refused-our-key-with-no-reason

That told me the file permissions were not right…

Hi Ravi Sir /Team,

There is one correction i.e, On authorized_keys permission is not working on 770 permission, its works only on 600. please check once.

@Helwi,

Please allow the port in Firewall also, if you are using any firewall like iptables or firewalld.

Dear Mr,

I have problem with port ssh, I can`t change the default port to custom port. I use 9899 for my custom port. Can you advice me step by step, because I follow your tutorial step by step to change port on sshd_config and also enabled port in selinux but its still not work.

When I try to connect using the port from other computer in the same network the error connection refused for port 22. When I try add comment -p 9899 in the end command are still refused.

Can you advice me?

Tthanks in advanced.
regard

Remove the public key from authorized_keys and the private key from Putty configuration.
