 전번에 해킹을 한번 당한적이 있었습니다만... 외국쪽인듯..
그 이후로 여기저기서 스펨메일도 많이오고 참 찝찝합니다... ㅜㅜ
그래서 TCP wrappers랑 iptable도 설정하고 이것저것 신경을 썼습니다만..
위와같은 메일이 루트로부터 조금씩 오다가..
오늘아침에는 600통 가까이 와있군요....
전부 같은 내용인데 다른부분이라면 메일 ID가 
collectd_XXX@netian.com 에서 XXX부분의 숫자만 바뀝니다.
이게 대체 무슨일이 벌어지는건지좀 조언 부탁드립니다.
 P.S 그리고 첨부된게 있었네요... 이런게..
