Re: [NETVAERK] Performance af iptables



From: "Jesper Lund" <sslug@sslug>
Den kan klare mange. Jeg har sat maks til 64k, og det giver ikke
problemer. Jeg har cirka 220 klient maskiner på.
Blot for at kommentere selve linux's evne til at håndtere mange klienter har jeg oplevet at man kan løbe tør for entries til caching af mac adresser.For os skete det når antallet af maskiner direkte forbundet (ikke routet) oversteg 1000. Løsning: Øg antallet i gc_thresh2 i proc:
echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh3


Blot nu vi taler om performance på linux og mulige problemer. (Iøvrigt har vi også en fw på - men en kommerciel en af slagsen)
