FreeBSD下SSH安装配置

sshd的配置文件一般位于/etc/ssh/sshd_config。

终端下:#ee /etc/ssh/sshd_config

---------------------------------------------

#Protocol 2,1

修改为：

Protocol 2

#ListenAddress 0.0.0.0

修改为：

ListenAddress 0.0.0.0

#PermitRootLogin yes

修改为

PermitRootLogin yes

（Linux上默认允许root用户登录，此处可不修改。）

修改完成后重启sshd:

/etc/rc.d/sshd restart

/etc/rc.conf 中，添加一个：

sshd_enable="yes"

FreeBSD SSH配置详解  

首先vi编辑/etc/inetd.conf,去掉ssh前的#，保存退出

编辑/etc/rc.conf

最后加入:sshd_enable="yes"即可

激活sshd服务：

techo#/etc/rc.d/sshdstart

用下面命令检查服务是否启动，在22端口应该有监听。

#netstat-an##checkportnumber22

最后

vi /etc/ssh/sshd_config,

记得修改完配置文件后，重新启动sshd服务器(/etc/rc.d/sshd restart)即可。
