hi all, have anyone tried changing the tcp setting in the source files ? for eg decreasing the TCP_KEEPALIVE_TIME from 2 hours to say 10 min --> (120*60*HZ) to (10*60*HZ) in include/net/tcp.h ?? changing the parameters in static unsigned long tcp_timeouts[] in net/ipv4/netfilter/ip_conntrack_proto_tcp.c from 5 DAYS to 4 HOURS or from 30 MIN to 10 MIN or both ??? will that change tcp keep alive or packets in conntrack in any way ??.. sorry for being too basic but am trying to think how it can help better my iptables/iproute firewal/bandwidth on my pc ! thankiing in advance A.H
