tcp & arp

[32xmax]

Any idea how do I define the following or which file contain the following entries,

A) tcp_conn_req_max_q0 should be at least 4096 to avoid TCP flood problems.
B) tcp_ip_abort_cinterval should be at most 60,000 to avoid TCP flood problems.
C) ip_respond_to_timestamp_broadcast should be 0
D) ARP timer (arp_cleanup_interval) should be at most 60,000

Have a look at the ndd man page

ndd -get /dev/tcp <parameter> - to display
ndd -set /dev/tcp <parameter> value - to set

Settings are not persistant over a reload, you probably need a custom script in /etc/rc2.d to set the values you want at boot time

Thanks for your time and help

I've just seen an example script (NOTE: I have only briefly looked at this and can NOT confirm that you should use it), This may give you and idea.

also,

If you make the changes using ndd, they will be lost on a reboot. I suggest making an S99ndd file in /etc/rc2.d/ that includes the ndd set's you may need.
