我注意到，当我login到我的服务器时，我有时会从syslog @ stock发送垃圾邮件。 在这台服务器上，我运行着一个由Laravel构build的网站和一个运行着20多个活跃用户的Teamspeak 3服务器。
我得到的消息是
Message from syslogd@stock at Jul 25 17:42:13 ... t of memory [4188] Message from syslogd@stock at Jul 25 17:42:13 ... t of memory [4194] Message from syslogd@stock at Jul 25 17:42:14 ... t of memory [4202] Message from syslogd@stock at Jul 25 17:42:14 ... t of memory [4208] Message from syslogd@stock at Jul 25 17:42:15 ... t of memory [4214] Message from syslogd@stock at Jul 25 17:42:15 ... t of memory [4224] Message from syslogd@stock at Jul 25 17:42:15 ... t of memory [4233] Message from syslogd@stock at Jul 25 17:42:16 ... t of memory [4241] 我对这些消息的含义感到困惑。
