iptables log rules to note the connection attempt should work.
Something like this in your /etc/sysconfig/iptables file that
otherwise is configured to let this traffic through with the ACCEPT rule:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1311 -j LOG
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1311 -j ACCEPT

iptables is always your friend for securing network ports.  You can
limit access to hosts from your own netblocks etc.
