MS81: IBM MQ Internet Pass-Thru

Download


Abstract

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

Download Description

IBM MQ Internet Pass-Thru (MQIPT) makes the passage of IBM MQ channel protocols into 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 IBM MQ protocol flows from an IBM MQ client or queue manager on the external Internet, to a destination queue manager inside the firewall. This enables inbound IBM MQ communication through the firewall from an address that is in the secure DMZ. This 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 an IBM MQ channel connection enables HTTP wrappers to be added to the protocol flow. This enables the IBM 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 IBM MQ connections, which simplifies firewall configuration when multiple IBM 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 IBM MQ channels through a variety of firewall and network topologies and facilitate many application models - particularly in the B2B environment.

MQIPT does not require any changes to IBM 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 an IBM 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
There are JRE updates available for all platforms: 

AIX = 7.0.10.50

Linux/Windows = 7.0.10.40

Solaris = 7.0.10.35

HPUX = 7.0.10.30

Users should download and install the JRE update package to update the JRE supplied in the MQIPT download.

Security Notice

Anon and NULL algorithms are no longer enabled by default in the latest JRE update. This affects the following CipherSuites in MQIPT:
SSL_ECDH_anon_WITH_AES_128_CBC_SHA
SSL_ECDH_anon_WITH_AES_256_CBC_SHA
SSL_ECDH_anon_WITH_NULL_SHA
SSL_ECDH_ECDSA_WITH_NULL_SHA
SSL_ECDH_RSA_WITH_NULL_SHA
SSL_ECDHE_ECDSA_WITH_NULL_SHA
SSL_ECDHE_RSA_WITH_NULL_SHA
SSL_RSA_WITH_NULL_MD5
SSL_RSA_WITH_NULL_SHA
SSL_RSA_WITH_NULL_SHA256

3DES ciphers are no longer considered secure and are disabled by default from MQIPT version 2.1.0.4.

To improve security, DES40_CBC ciphers are no longer enabled by default in the JRE update to 7.0.10.35, and any later JRE updates. This affects the following CipherSuites in MQIPT:
  SSL_RSA_EXPORT_WITH_DES40_CBC_SHA
  SSL_KRB5_EXPORT_WITH_DES_CBC_40_MD5
  SSL_KRB5_EXPORT_WITH_DES_CBC_40_SHA

If you are aware of the potential hazards but still have a need to use one of these CipherSuites, you can add support for it by removing the corresponding algorithm from the list of disabled algorithms (jdk.tls.disabledAlgorithms) in the java.security file, found in mqipt_path/java/jre/lib/security/, where mqipt_path is the location where MQIPT is installed.

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.
