우선 급한대로 해당 아이피는 아래와 같이 막아놓았습니다.
root@ns log# cat /etc/hosts.deny
#
# hosts.deny This file describes the names of the hosts which are
# *not* allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow. In particular
# you should know that NFS uses portmap!

이외에 다른 수상한 아이피들도 많이 보입니다.
서버도 좀 이상합니다.
시간나는대로 수시로 서버 살펴보고 조취를 취하겠습니다.
제가 요즘 시간이 없어서 따로 날잡고 살펴보고 싶은데 그러질 못하네요.. 죄송합니다.
p.s
새해 복 많이 받으세요
