Linux Iptables Open LDAP Server TCP Ports 389 and 636

Posted on in Categories , , , , , , , last updated August 16, 2009

The default Iptables configuration under CentOS / Red Hat / RHEL / Fedora Linux does not allow inbound access to LDAP service. How do I update iptables settings to allow access to the LDAP primary TCP #389 and encrypted-only TCP # 636 ports, while keeping all other ports on the server in their default protected state?

My Squid proxy server running on port 3128. Since this is frequently scanned by adversaries looking for proxy servers; I’ve changed port to 10000 and restart squid. But my squid is not working on port # 10000 it only works on port # 3128? How do I force Squid to listen on uncommon port under CentOS Linux v5.3?
