使用com.enterprisedt.net.ftp庫連接客戶在HPUnix上的FTP服務器，不定時的出現連接不上去的情況，但是使用FTP客戶端卻可以直接連接。
客戶不讓telnet主機，只好要了syslog文件自己分析。
看了一下，相關FTPD的有三個記錄
我不管連接的記錄（ftp里面的conn操作）,只處理login和logout操作。

如下

Dec 23 05:01:44 服務器主機名 ftpd[18609]: FTP LOGIN FROM 客戶機IP地址 [客戶機IP地址], fileplat
Dec 23 05:03:11 服務器主機名 ftpd[18609]: FTP session closed
Jan 28 09:28:48 服務器主機名 ftpd[18609]: FTP LOGIN FROM unicom-1 [客戶機IP地址], fileplat
Jan 28 09:28:50 服務器主機名 ftpd[18609]: FTP session closed
Feb 17 21:37:35 服務器主機名 ftpd[18609]: FTP LOGIN FROM unicom-1 [客戶機IP地址], fileplat
Feb 17 21:58:01 服務器主機名 ftpd[18609]: exiting on signal 14
Feb 19 02:38:34 服務器主機名 ftpd[18609]: FTP LOGIN FROM 客戶機IP地址 [客戶機IP地址], fileplat
Feb 19 02:38:35 服務器主機名 ftpd[18609]: FTP session closed

ftpd后面的方括號里面是客戶登陸之后的進程號（線程號？？？），確定一個ftp Session。正常退出使用Ftp Session closed。否則是exiting on signal.
下面是簡單的程序
程序將一個ftp登陸的數據操作記錄到數據庫，這樣可以分析出客戶連接主機的頻率和每次時長

因為只用一次，代碼很土
