下载DenyHosts包
[root@localhost ~]# wget Http://jaist.dl.sourceforge.net/project/denyhosts/denyhosts/2.6/DenyHosts-2.6.tar.gz
安装DenyHosts
[root@localhost ~]# tar xf DenyHosts-2.6.tar.gz[root@localhost ~]# cd DenyHosts-2.6[root@localhost DenyHosts-2.6]# python setup.py install
制作配置文件
[root@localhost DenyHosts-2.6]# cp denyhosts.cfg-dist /etc/denyhosts.cfg[root@localhost DenyHosts-2.6]# cp daemon-control-dist daemon-control[root@localhost DenyHosts-2.6]# chown root daemon-control[root@localhost DenyHosts-2.6]# chmod 700 daemon-control
修改配置文件
将daemon-control中的#DENYHOSTS_CFG = "/usr/share/denyhosts/denyhosts.cfg"改为 DENYHOSTS_CFG = "/etc/denyhosts.cfg"
启动
[root@localhost DenyHosts-2.6]# ./daemon-control start(注意相对路径)
默认允许五次,测试发现登陆失败五次之后不允许登陆
[root@localhost ~]# ssh abc@172.16.1.16abc@172.16.1.16's passWord: Permission denied, please try again.abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).[root@localhost ~]# [root@localhost ~]# ssh abc@172.16.1.16abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).[root@localhost ~]# ssh abc@172.16.1.16abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).[root@localhost ~]# ssh abc@172.16.1.16abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied, please try again.abc@172.16.1.16's password: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).[root@localhost ~]# ssh abc@172.16.1.16ssh_exchange_identification: read: Connection reset by peer
查看hosts.deny文件
登陆连续失败之后就会把ip地址写在hosts.deny文件
172.16.1.112的ip已经被限制,到此功能实现。
