# nddconf: network tunable parameters for Streams TCP/IP # # @(#)B.11.31_LR $Revision: 1.1.119.4 $ $Date: 97/04/23 15:18:44 $ # # Network tunable parameters read in by the networking startup script - # /sbin/init.d/net or by executing "ndd -c". # # TRANSPORT_NAME: Name of transport component, valid names are: # ip, tcp, udp, rawip, and arp. # # NDD_NAME: Name of ndd tunable parameter # # NDD_VALUE: Value for ndd tunable parameter # # Note: Set all clock time values in milliseconds. For example, # 240000 = 4 minutes # # Note: The ndd tunable parameters specified in this file must be writable. # "ndd -c" can only handle the write operation. # # For each additional tunable parameter, add a set of variable assignments # like the ones below, changing the index to "[0]", "[1]" et cetera. # Index must be starting from 0 and they must be in sequential order. # Missing index values inside the array range is not supported. # # # Example 1: Change the interval for sending the first keepalive probes # for idle TCP connection to one hour # TRANSPORT_NAME[0]=tcp # NDD_NAME[0]=tcp_keepalive_interval # NDD_VALUE[0]=3600000 # # # Example 2: Change the interval for sending keepalive probes to 1 minute # when TCP is detached. (e.g.FIN_WAIT_2) # TRANSPORT_NAME[1]=tcp # NDD_NAME[1]=tcp_keepalive_detached_interval # NDD_VALUE[1]=60000 # # # Example 3: Change the amount of time TCP endpoints persist in TIME_WAIT # state to 30 seconds. # TRANSPORT_NAME[2]=tcp # NDD_NAME[2]=tcp_time_wait_interval # NDD_VALUE[2]=30000 # # Example 4: Change the UDP default ttl parameter to 128 # TRANSPORT_NAME[3]=udp # NDD_NAME[3]=udp_def_ttl # NDD_VALUE[3]=128 # # Example 5: Change the amount of time that ARP entries can stay in # ARP cache to 10 minutes. # # TRANSPORT_NAME[4]=arp # NDD_NAME[4]=arp_cleanup_interval # NDD_VALUE[4]=600000 # # TRANSPORT_NAME[0]=ip6 NDD_NAME[0]=ip6_addr_sel_enable NDD_VALUE[0]=0 # # the following is due to the WARNING from patch PHNE_43814 TRANSPORT_NAME[1]=tcp NDD_NAME[1]=tcp_sack_enable NDD_VALUE[1]= 0
