Abstract

WebSphere MQ Internet Pass-Thru is a WebSphere MQ base product extension that can be used to implement messaging solutions between remote sites across the internet.

Download Description

WebSphere MQ Internet Pass-Thru (known as MQIPT) is a WebSphere MQ base product extension that can be used to implement messaging solutions between remote sites across the internet.

It makes the passage of WebSphere MQ channel protocols in to and out of a firewall simpler and more manageable, by tunnelling the protocols inside HTTP or by acting as a proxy.

MQIPT has an Administration graphical user interface (GUI) for managing one or more MQIPT servers.

MQIPT runs on the platforms indicated in the Hardware and Software requirements below. It uses the JRE supplied.


Possible Uses
Used as a proxy, MQIPT is placed in the De-Militarized Zone (DMZ) on an Internet firewall and relays WebSphere MQ protocol flows from a WebSphere MQ client or Queue Manager on the external Internet, to a destination Queue Manager inside the firewall. This enables inbound WebSphere MQ communication through the firewall from an address which is in the secure DMZ, which is likely to be more acceptable to firewall administrators than an arbitrary external Internet address.

Placing a pair of MQIPT servers in the path of a WebSphere MQ channel connection enables HTTP wrappers to be added to the protocol flow - which enables the WebSphere MQ connection to pass inbound through an HTTP application firewall, or outbound through an HTTP proxy. A pair of MQIPT servers can also be used to encrypt all data flows, using SSL or TLS.

MQIPT can also act as a concentrator of WebSphere MQ connections, which simplifies firewall configuration when multiple WebSphere MQ clients or Queue Managers require access through an Internet firewall.

MQIPT can be configured to act as a SOCKS client or SOCKS server, for making outbound connections. The Administration GUI can also use a SOCKS proxy to connect to an MQIPT server.

MQIPT can be used with the IBM Network Dispatcher, to provide enhanced availability and load balancing across many servers.

These modes of operation of MQIPT give greater flexibility to the connection of WebSphere MQ channels through a variety of firewall and network topologies and facilitates many application models - particularly in the B2B environment.

MQIPT does not require any changes to WebSphere MQ application code, and only a minor modification to the hostname/port setting in MQ channel definitions.

Skill Level Required
This SupportPac should be installed by a WebSphere MQ system administrator or network administrator. Configuration and implementation of this SupportPac requires a basic understanding of TCP/IP networking and a knowledge of internet firewall administration.

New in this Release
• Ability to install an updated JRE for security fixes.

Installation Instructions

Note that the installation method has changed from the previous release. MQIPT 2.0 and earlier used a platform-specific installation method, such as AIX installp and Linux RPM. However, MQIPT 2.1 has no installer: simply unpack the supplied file archive in your chosen installation directory. The following guidance is provided to assist with installation of MQIPT 2.1.

To install the SupportPac on a Windows platform:
• Download file ms81_x86_nt_4.zip to a temporary directory (for example C:\temp).
• Create a new directory where you want MQIPT to be installed (for example C:\MQIPT).
• Move the downloaded ms81_x86_nt_4.zip to the new MQIPT installation directory.
• Uncompress using InfoZip Unzip. If you use other unzip programs, ensure you specify the option to re-create stored directories.
• It is recommended to make the MQIPT installation directory read-only by revoking write permissions from all users.
• To create MQIPT icons on the Start menu, run the following command from an Administrator command prompt:
C:\MQIPT\bin\mqiptIcons -install installation_name

To install the SupportPac on a UNIX or Linux platform, you must log on as the root user. Then perform the following steps:
• Download the tar file to a temporary directory (for example /tmp).
• Create a new directory where you want MQIPT to be installed (for example /opt/mqipt).
• Move the downloaded tar file to the new MQIPT installation directory, for example:
mv /tmp/ms81_x86_linux_2.tar /opt/mqipt
• Unpack the tar file, for example:
cd /opt/mqipt
tar xf ms81_x86_linux_2.tar
• To increase security, set the file permissions for your installed files so that they are read-only. For example:
chmod -R /opt/mqipt/* a-w
Note: failure to run the tar command as root is likely to result in "permission denied" errors.

For more information about installation and migration from the previous release, refer to the readme and PDF documentation.

JRE update installation instructions:
Periodically IBM releases an updated JRE for use with MQIPT in order to provide the latest Java security fixes. Updated JREs for MQIPT can be downloaded via the Download package link, in the Security Update JRE for MS81 section. To install a new JRE for MQIPT, follow the instructions here. The MQIPT version number is not affected by installing a new MQIPT JRE. To determine which MQIPT JRE is currently installed, use the mqiptVersion -v command.
