在Linux系统安装过程中，程序脚本也自动地被安装了进来。如果发现你需要编辑程序脚本并希望能增加对Secure Shell的启动，你可以将下列的程序脚本添加进来。

表1 启动脚本位置

操作系统 　　　　　启动程序脚本 　　操作系统 　　　启动程序脚本

Slackware Linux 　　/etc/rc.d 　　　　Irix 　　　　　/etc/rc*.d

Red hat Linux　　　　 /etc/rc*.d　　　 AIX 　　　　　　/etc

Solaris　　　　　　　 /sbin/rc*.d　　　 DEC UNIX 　　　/sbin/rc*.d

HP-UX 　　　　　　　　/sbin/rc*.d

我的UNIX系统是Slackware Linux系统，网络初始化程序脚本为/etc/rc.d/inet2，在这个脚本中，你将发现Secure Shell已经启动。如果你希望做到这一点，可以编辑启动程序脚本以正确的路径将Secure Shell守护进程增加进去，并设置你所需要的选项。

#！/bin/sh
#
# rc.inet2 This shell script boots up the entire INET

# system.Note, that when this script is used to

# also fire up any important remote NFS disks

# (like the /usr distribution),care must be

# taken to actually have all the needed binaries
