TCP/IP applications, protocols, and services


Find useful information about how to take advantage of TCP/IP services and applications.

Bootstrap Protocol
Bootstrap Protocol (BOOTP) provides a dynamic method for associating workstations with servers. It also provides a dynamic method for assigning workstation Internet Protocol (IP) addresses and initial program load (IPL) sources.

Connecting to the Internet
If you want to connect your i5/OS operating system to an Internet service provider (ISP), or configure your operating system as a Web data server or application server, you can use the Internet Setup wizard to connect to the network.

Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) is a TCP/IP standard that uses a central server to manage IP addresses and other configuration details for an entire network.

Directory Server (LDAP)
IBM Directory Server for iSeries (hereafter referred to as Directory Server) is a function of the i5/OS that provides a Lightweight Directory Access Protocol (LDAP) server. LDAP runs over Transmission Control Protocol/Internet Protocol (TCP/IP) and is popular as a directory service for both Internet and non-Internet applications.

Domain Name System
Domain Name System (DNS) is a distributed database system for managing host names and their associated Internet Protocol (IP) addresses.

Use this information to plan for, configure, use, manage, and troubleshoot e-mail on your system.

File Transfer Protocol
You can set up your IBM System i platform to send, receive, and share files across networks by using File Transfer Protocol (FTP). You can also rename, add, and delete files across a network using FTP. Before you set up your system to transfer files, have TCP/IP configured and started on your system.

IP filtering and network address translation
IP filtering and network address translation (NAT) act like a firewall to protect your internal network from intruders.

iSeries NetServer
iSeries Support for Windows Network Neighborhood (iSeries NetServer) is an IBM i5/OS function that enables Windows 2000, Windows XP, Windows Server 2003, and Windows Vista clients to access i5/OS shared directory paths and shared output queues.

HTTP Server
The IBM HTTP Server for i5/OS documentation contains getting started, task oriented, and scenario-based information, supporting reference material, and conceptual information. The V5R4 IBM Web Administration for i5/OS™ interface support information is also included.

Quality of Service
The i5/OS quality of service (QoS) solution enables the policies to request network priority and bandwidth for TCP/IP applications throughout the network.

Remote Access Services: PPP connections
Point-to-Point Protocol (PPP) is an Internet standard for transmitting data over serial lines.

Remote Execution
The Remote Execution (REXEC) server is a Transmission Control Protocol/Internet Protocol (TCP/IP) application that allows a client user to submit system commands to a remote system. The Remote Execution Protocol (REXEC) allows processing of these commands or programs on any host in the network. The local host then receives the results of the command processing.

Route Daemon
The Route Daemon (RouteD) provides support for the Routing Information Protocol (RIP) on the System i platform.

Simple Network Time Protocol
Simple Network Time Protocol (SNTP) is a time-maintenance application that you can use to synchronize hardware in a network.

TCP/IP routing and workload balancing
You can route and balance the TCP/IP traffic of your system by using its integrated routing capabilities to eliminate the need for an external router.

TCP/IP subnet calculator advisor
Calculate new subnets of IP addresses for class A, class B, and class C network addresses.

Telnet is a protocol that enables you to log onto and use a remote computer as though you were connected directly to it within the local network.

Trivial File Transfer Protocol
Trivial File Transfer Protocol (TFTP) is a simple protocol that provides basic file transfer function with no user authentication.

User-defined servers
The System i platform supports custom or user-defined servers. This support enables you to add custom servers and to perform administrative tasks for them, such as stopping, starting, and monitoring servers, in the same way as you administer servers that are supplied on the System i platform.

Virtual private networking
A virtual private network (VPN) allows your company to securely extend its private intranet over the existing framework of a public network, such as the Internet. With VPN, your company can control network traffic while providing important security features such as authentication and data privacy.
