Banzai!

Tega je v logih na tone, hm megabajte :)) Kaj se da ukrenit proti temu?

Naslednja zadeva je pa tale:
Mar 25 15:51:09 capybara kernel: Warning: possible SYN flooding. Sending cookie
Mar 25 15:51:12 capybara kernel: Warning: possible SYN flooding. Sending cookie
Mar 25 15:51:13 capybara kernel: validated probe(441008a4, 89e02c1, 2077, 80, -192278241)
Mar 25 15:51:13 capybara kernel: validated probe(57142399, 89e02c1, 1542, 80, 158678831)


Tegale je v logih tudi noro velik, pravzaprav, je vceraj od 15:51 pa do
21:32 samo tole v logih, recimo vsake deset sekund po ene deset vrstic
tega sranja... Dokler se bogi masini ni zmesalo in se je sesula... :(
 A je kak nacin, da se ugotovi od kje se to pocne? Ali pa da se nekako
tega ubrani?

David!
