For auditing purpose, HP has recommended us the following N/w tunable parameters
tcp_syn_rcvd_max
4096
arp_cleanup_interval
60000
ip_forward_src_routed
0
ip_forward_directed_broad
casts
0
ip_respond_to_timestamp
0
ip_respond_to_timestamp_
broadcast
0
ip_respond_to_address_ma
sk_broadcast
0
ip_respond_to_echo_broad
cast
0
ip_forwarding
0
ip_send_redirects
0
when i have checked the /etc/rc.config.d/nddconf file i am able to see the following parameters and those parameters are also commented.
# 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
May i know how can we set the other parameters into the configuration file. After parameters are added whether we have to stop and start any service?
May i know the impact if we add the above parameters.
My OS version is HP-UX 11.11
OS models: rp8440, rp7440 and rp3440
Solved! Go to Solution.

Re: N/w parameters Tuning
meaning ..you are non-compliance for the auditing issues,raised by HP
hence non of the "nddconf" or network parameter are in USE. becoz they are commented
if you there are in "USE" to need to tune according to the requirement from HP recommendations
