Zatuhnuti konzole a pocitace - dlouhe

Středa Duben 5 07:52:04 CEST 2000

Dobry den,

tak se mi prihodila nedavno podivna vec. Na jednom pocitaci s RH 5.2,
kernel 2.0.36, 160 MB RAM, K6 233, na kterem bezi apache, squid a dost
dalsich veci (maskarada) se stalo toto. Byl jsem prihlaseny jako root na
3 konzolich a najednou prestala reagovat klavesnice a na obrazovku se
zacaly vypisovat hlasky o odmitnutych paketech z ipfwadm, ktere jsou
normalne v /var/log/messages. Neslo nic delat, tak jsem se prihlasil
vedle z NT pres ssh a ze s tim neco provedu. Nepodarilo se mi ale ani
sestrelit konzoli, ani na reboot ci halt to nereagovalo. Reboot dopadl
tak, ze se nesnesitelnym zpusobem rozpiskal speaker. Psychicky jsem ten
randal nevydrzel a nakonec mi nezbylo :(( nic jineho nez kouzelne
tlacitko... V logu jsem potom nasel nasledujici:

Stroj byl v te dobe dost vytizeny, ale nikdy se mi nic podobneho
nestalo...

Mohl by mi nekdo vysvetlit, co se stalo?

Dekuji predem vsem
