Operating System TCP/IP Ports

The directory server uses the following ports by default:

• Administration connector, default port 4444

• LDAP, default port 389

• LDAPS, default port 636

• SNMP, default port 161 if configured

• JMX, default port 1689

• Replication port 8989

  Note - The ports can differ between root and non-root users for some protocols.

File Descriptor Limits

On some Linux systems, the default file descriptor limit is set to 1024. This value might be too small when processing the total number of client connections, database files, and log files that the directory server requires to operate. It is strongly recommended that this file descriptor limit be increased to 64K or (65536 field descriptors).
