• Disabling IPtables configuration which is blocking Smarts Service Assurance Manager (Smarts SAM) keepalive feature
• Disabling the Smarts keepalive feature
• Disabling Linux firewall in Smarts SAM environment

Environment

Smarts 10.X / 2.X

Resolution

This is the command for disabling iptables configuration:

To Disable / Turn off Linux Firewall (Red hat/CentOS/Fedora Core), type the following two commands (you must login as the root user):

/etc/init.d/iptables save
/etc/init.d/iptables stop

OR

chkconfig iptables off
 service iptables save
 service iptables stop

If you do not want to turn off Linux firewall because of security, then the keepalive feature can be disabled in the Smarts product as follows:

<BASEDIR>/smarts/bin/sm_edit conf/runcmd_env.sh 
SM_DISABLE_KEEPALIVES = 1

Restart your Smarts domain in order for the change to take effect.
