Configure ssh for centos

Centos configuration ssh-Linux Enterprise Application-Linux server application information. The following is a detailed description. When you install a Sever version of CentOS in VMware, the content in the terminal cannot be rolled, which is inconvenient. Good remote logon in win (an Xshell in win ). Ssh is installed by default. Only hosts access problems.

1. Add sshd: ALL at the end of the hosts. deny file

Deny all access requests

[Root @ localhost ~] # Vi/etc/hosts. deny

#
# Hosts. deny This file describes the names of the hosts which are
# ** Not * allowed to use the local INET services, as decided
# By the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# The new secure portmap uses hosts. deny and hosts. allow. In particle
# You shoshould know that NFS uses portmap!
Sshd: ALL

2. Add sshd: 192.168.0 at the end of the hosts. allow file.

It indicates that hosts from 192.168.0.1 to 254 are allowed on the Intranet.

[Root @ localhost ~] # Vi/etc/hosts. allow
#
# Hosts. allow This file describes the names of the hosts which are
# Allowed to use the local INET services, as decided
# By the '/usr/sbin/tcpd' server.
#
Sshd: 192.168.0.

3. Restart ssh
[Root @ localhost ~] #/Etc/rc. d/init. d/sshd restart
Stop sshd: [OK]
Start sshd [OK]

Now, you can log on with putty and Xshell (Xmanager.
