操作如下：
cd /home/bbs/etc
cp /etc/ssh/sshd_config /home/bbs/etc
ssh-keygen -t rsa1 -f ssh_host_key

遇到错误：
etc/ssh_config line 9:Bad configuration option:protocol
--
FROM 59.108.40.*

改为1，也是这样的错误
【 在 JulyClyde (我的月份过去了) 的大作中提到: 】
: protocol应该是1吧？
--
FROM 59.108.40.*

注释掉 #protocol 2 这一行后 会出现：
etc/ssh_config line 15:Bad configuration option:useprivilegeseparation

生成key没问题
启动sshbbsd的时候出的问题
【 在 fancyrabbit (fancy★一摩尔时光) 的大作中提到: 】
: 你给个简明说明好不好，被你绕的晕头转向+邮件狂骚扰...
: 生成key的时候出的问题还是启动sshbbsd时候出的问题...
: sshd_config里面HostKey之类的改了么？
