Witajcie, mam problem ze \\"znalezieniem winnego\\", rzecz w tym, że posiadam komputer:
- Pentium II 350MHz
- 64MB Ram
- 3,2 GB HDD
- wifi ralink rt2400
- Zainstalowany Slackware 10 (bez upgrade)
Komputer służy jako serwer/router dla sieci domowej, forwardując pakiety z wifi na ethernet. Na serwerze działa trochę usług:
Starting nmap 3.50 (
http://www.insecure.org/nmap/ ) at 2006-04-08 22:46 CEST
Interesting ports on localhost (127.0.0.1):
(The 1649 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
37/tcp open time
80/tcp open http
113/tcp open auth
139/tcp open netbios-ssn
445/tcp open microsoft-ds
587/tcp open submission
631/tcp open ipp
Serwer działał 24h przez 3 tygodnie bez najmniejszego problemu - do dziś. Dziś po raz
pierwszy system się \\"wykrzaczył\\". Po restarcie działał nadal bezproblemowo przez 3
godziny, po kolejnym restarcie już tylko 3 minuty. Po kolejnym około godzinę. Piszę
ten post po 3 uruchomieniu go. Bardzo Was proszę, o pomoc, czy jest jakiś plik
systemowy, gdzie zapisywane są informacje o skutkach awarii? Może gdzieś zapisywana
jest historia powiedzmy ostatniej sesji, uruchomionych procesów itp... Być może
pomocne będzie to co wyrzuca dmesg:
