vps一连接ftp，终端就弹出这些信息.还有个nginx日志等级的问题

Question

1、登陆ssh终端，打开wordpress后台，比如在后台点一个升级版本，这里就是通过FTP自动升级了，终端就会不停的跳下面一段：

Message from syslogd@jjhr at Jul  9 21:11:58 ...

 kernel:[1265328.179043] nf_ct_ftp: dropping packetIN= OUT=lo SRC=205.185.115.53 DST=205.185.115.53 LEN=105 TOS=0x00 PREC=0x00 TTL=64 ID=50598 DF PROTO=TCP SPT=21 DPT=52252 SEQ=245533523 ACK=348264109 WINDOW=256 RES=0x00 ACK PSH URGP=0 OPT (0101080A4B66CC524B66B3DC) UID=0 GID=0

这个不知道是什么情况的。

=============================================

2、我想请问一下nginx日志等级应该怎么设置。

我看了现在的nginx日志文件，里面全部都是DEBUG的。

请问这个要怎么设定，还有这些日志有哪些等级的。

日志文件太大，这是最后100行的内容：
