Change ARP Entery

[leonid1890]

Hello,

I have Check Point's 1590 Appliance R80.20.50

I am trying to change ARP aging timeout.

I didn't find any reference about it beside sk42182 
which said to chage it in /etc/sysctl.conf -> but it isn't located there.

I found it (/etc/sysctl.conf) in different location "/sbin/sysctl"
but I see everthing there in gibberish.

sk42182 is for SPLAT & GAiA and not supported on GAiA Embedded ! You can use sysctl -a | grep gc_stale_time to get the current time span, but a .conf file is not present. So only the following command can be used:

[Expert@seven-eleven]# sysctl -w net.ipv4.neigh.WAN.gc_stale_time=120

This will set net.ipv4.neigh.WAN.gc_stale_time = 120 ! To make the change permanent you have to addf the sysctl -w lines to userScript, see sk52520: How to run commands at boot on an SMB appliance -- userScript
