NOTICE : System is i686-unknown-linux2.6.9-34.EL (1 processor).

WARNING: 1011MB of physical memory is available on the system. 1024MB is 
recommended for best performance on large production system.

NOTICE : The net.ipv4.tcp_keepalive_time is set to 7200000 milliseconds
(120 minutes).  This may cause temporary server congestion from lost
client connections.

WARNING: There are only 1024 file descriptors (hard limit) available, which
limit the number of simultaneous connections.

WARNING: There are only 1024 file descriptors (soft limit) available, which

Example 7.1. dsktune Output

7.7.2. Common Installation Problems

There are several common problems that can come up during the setup process, generally relating to
network or naming problems. These problems and workarounds and solutions are described below.

For system information, try running the 

dsktune

 utility to identify potential hardware problems.

7.7.2.1. Problem: Clients cannot locate the server

Solution.

First, modify the hostname. If that does not work, use the fully-qualified domain name, like

www.domain.com

, and make sure the server is listed in the DNS. If that does not work, check the IP

address.

If the NIS domain is not the same as your DNS domain, check your fully-qualified host and domain
name.

7.7.2.2. Problem: The port is in use

When setting up a Directory Server instance, you receive an error that the port is in use. This is very
common when upgrading or migrating an existing server.

Solution

This error means that you did not shut down the existing server before beginning the upgrade or
migration. Shut down the existing server, and then restart the upgrade process.

If this occurs during a setup process, it may mean another server is already using this port. Verify that
the port you selected is not in use by another server.

7.7.2.3. Problem: Forgotten Directory Manager DN and password

Solution.

By default, the Directory Manager DN is 

cn=Directory Manager

. If you forget the Directory

Manager DN, you can determine it by checking the 

nsslapd-rootdn

 attribute in the 

dse.ldif

 file,

in the 

/etc/dirsrv/slapd-

instance_name

 directory.
