| GNU Screen的一个功能是锁定屏幕. 
  
  手册页说:  
  lockscreen Lock this display. Call a screenlockprogram (/local/bin/lck or
 /usr/bin/lock or a builtin if no other
 is available). Screen does not accept
 any command keys until this program
 terminates. Meanwhile processes in the
 windows may continue,as the windows
 are in the `detached’ state. The
 screenlock program may be changed
 through the environment variable
 $LOCKPRG (which must be set in the
 shell from which screen is started)
 and is executed with the user’s uid
 and gid. Warning: When you leave other
 shells unlocked and you have no
 password set on screen,the lock is
 void: One could easily re-attach from
 an unlocked shell. This feature should
 rather be called ‘lockterminal’.
 如果我登录Linux控制台启动屏幕,然后锁定会话然后离开,那么一个人可以退出屏幕并使用我的凭据下的系统.手册页上面的部分对我来说并不完全清楚.假设攻击者没有其他系统访问权限,他们将不会重启系统. 解决方法不,你很安全.如果我不得不猜测你对这个人工页面感到困惑的话,我会说这是警告部分.他们试图说的是,屏幕会话本身并不是锁定的,而是该特定终端上的实例.如果你留下攻击者可以以用户身份启动屏幕的shell,他们就可以访问你在锁定屏幕中运行的内容. 我不确定为什么这是一个场景.如果它是服务器,为什么不用SSH登录?如果它是台式机 – 为什么不运行xlock呢?
