CentOS 5
Password Authentication
  Before configuration, it's neccessary to set config on router that tcp packets to port 22 of the server can pass through.

[1] Configure SSH server for Windows clietnts' computer to be able to login from them. This is the way with Password Authentication.
[root@ns ~]#
vi /etc/ssh/sshd_config


#MaxAuthTries 6
# line 39: uncomment and change 'no'

PermitRootLogin
no


# line 59: uncomment

PermitEmptyPasswords no
PasswordAuthentication yes

[root@ns ~]#
/etc/rc.d/init.d/sshd restart

[2] Get an apprication which you can login from Windows clients. I show an example with using Putty on this site like below.

Input your server's IP address and Click 'Open' button. ( Following example shows IP address 192.168.0.17, but this is the one in my environment, so please input IP address which you set on your own environment. )
