해킹시도에 의한 kernel panic

안녕하십니까? 오늘과내일의 홍석범입니다.

첫줄의 로그는 단순한 ssh 에 대한 brute force 접속 시도이며 커널패닉과는 무관합니다.
커널 패닉 관련 메시지는 HW와 관련된 것이므로 CPU나 RAM 등 HW를 교체해 보셔야 할 것 같습니다.

감사합니다.

커널 패닉입니다.

해킹을 시동한 흔적이 남아있는데... 이것때문에 그런건 아닌지 의심이 되는군요.

원인을 아실것 같은 고수님들의 조언 부탁드립니다.

CentOS 4.4입니다. 아래는 message 로그파일 내용

Jan 21 03:30:43 ns sshd(pam_unix)[12681]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=63.87.234.10
Jan 21 03:30:47 ns sshd(pam_unix)[12683]: check pass; user unknown

미국IP로 확인된 내용이 하루사이에 약 1만라인정도 되네요.

위와같이 커널 패닉이 발생하며 다운되네요.

고수님들의 조언 부탁드립니다.
