To run the Directory Server using port

 

 

numbers less than 1024, such as the default

 

 

port 389, you must setup and start the

Table 2.2. Red Hat Enterprise Linux Operating System and Hardware Requirements

2.2.1. Red Hat Enterprise Linux Patches

The default kernel and glibc versions for Red Hat Enterprise Linux 4 and 5 are the only required versions for the Red Hat Directory Server host machine. If the machine has a single CPU, the kernel must be presented in the form kernel-x.x.x.x. If the machine has multiple CPUs, the kernel must be presented the form kernel-smp-x.x.x.x. To determine the components running on the machine, run rpm -qa.

Run the dsktune utility to see if you need to install any other patches. dsktune helps verify whether the appropriate patches are installed on the system and provides useful information for tuning your kernel parameters for best performance. For information on dsktune, see Section 2.1, “Using dsktune”.
