iPtable Lütfen bi bakın.

Öncelikle s.a
iptables ile alakali büyük bi sorun yaşıyorum
sunucu hergun duzenli olarak sabah 11 : 30 da donuyor ( kapanıyor ) .
ssh dan iptablesa restart atmadan aktif olmuyor ipler.
iptables kurallarını
iptables -F
komutuyla 0 ladıgım halde kendi kendine yeniden kurallar aktif oluyor ve ertesi gün yeniden kapaniyor sunucu
bi çok yerde araştırma yaptim ama hiçbir sonuc bulamadım bulduklarımda hiç bir sonuc vermedi. yardımlarınızı bekliyorum tşkler.

Herhangi bir firewall kullanıyormusunuz ?

dedicate firmasinin kurdugu var sanirim fakat bunlar ne anlama geliyor hiçbi fikrim yok
