FreeBSD下如何开启SSH

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/sshd start

用下面命令检查服务是否启动，在22端口应该有监听。

#netstat -an ## check port number 22

最后

vi /etc/ssh/sshd_config,

下面是我的配置文件：(/etc/ssh/sshd_config) ####################################################

# $OpenBSD: sshd_config,v 1.72 2005/07/25 11:59:40 markus Exp $ # $FreeBSD: src/crypto/openssh/sshd_config,v 1.42.2.1 2005/09/11 16:50:35 des Exp $

# This is the sshd server system-wide configuration file. See # sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with # OpenSSH is to specify options with their default value where # possible, but leave them commented. Uncommented options change a # default value.

# Note that some of FreeBSD’s defaults differ from OpenBSD’s, and # FreeBSD has a few additional options.

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。
