I am getting an error

ssh: connect to host 10.5.6.206 port 22: Connection refused

when I am trying to login from a remote machine using LAN.It used to work fine earlier but changed since the selinux configuration was changed from enforcing to permissive.

output of ssh -v :

 OpenSSH_5.6p1, OpenSSL 1.0.0j-fips 10
 May 2012 debug1: Reading configuration

@Nagaraju What if you switch back SELINUX to enforcing? Can you do that on target machine ed ssh -v one more time?

Even then I get the same error

@Nagaraju I guess it is not a SELINUX issue then. Are you able to login to the target server in some way?

No as your answer suggests sshd daemon is not running.How should I fix it.when I do /etc/init.d/sshd start it says "Job failed. See system logs and 'systemctl status' for details."

On the server (10.5.6.206) - does systemctl status sshd.service say anything interesting? Anything in /var/log/messages telling why sshd does not start? Do: /usr/sbin/sshd - this will print (if) any configuration errors in /etc/ssh/sshd_config

Thanks for your replies.I got the solution. When I did check the output of

/usr/sbin/sshd -D -d

debug1: sshd version OpenSSH_5.6p1

debug1: read PEM private key done:

type RSA debug1: private host key: #0

type 1 RSA debug1: read PEM private

key done: type DSA debug1: private host key: #1 type 2 DSA

/var/empty/sshd must be owned by root and not group or world-writable.

Directory permissions messed up when I was trying to execute a perl script in /var/www/cgi-bin/.

So when I changed back the permissions back to 755(rwx rx rx) ssh works fine now.
