这是来自机器人攻击吗？

Question

我今天检查了error_log，发现这个可疑：

    [Mon Nov 27 01:18:36 2011] [error] [client omitted] 
    File does not exist: /var/www/domain.com/htdocs/robots.txt
    [Mon Nov 27 01:18:45 2011] [error] [client omitted] 
    File does not exist: /var/www/domain.com/htdocs/robots.txt
    [Mon Nov 27 01:24:38 2011] [error] [client ommited] 
    script '/var/www/domain.com/htdocs/proxy-1.php' 
    not found or unable to stat
    [Mon Nov 27 01:24:57 2011] [error] [client omitted] 
    script '/var/www/domain.com/htdocs/judge112233.php' 
    not found or unable to stat

我说可疑，因为我是目前唯一使用该网站的人，所以我知道所有页面，我永远不会访问上面的那些页面。那么这是机器人攻击吗？

对我来说看起来更像是一个网络爬虫。
