New IBM HTTP Server for i supports SNI in IBM i 7.1

SNI (Server Name Indication) is an extension to the SSL and TLS protocols that indicates what hostname the client is attempting to connect to at the start of the handshaking process. This allows a server to present multiple certificates on the same IP address and port number and hence allows multiple secure (HTTPS) websites to be served off the same IP address without requiring all those sites to use the same certificate. It is the conceptual equivalent to HTTP/1.1 virtual hosting for HTTPS. For more information about SNI please refer to https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_74/rzain/rzainappdefssni.htm

With SNI, you can have many virtual hosts sharing the same IP address and port, and each one can have its own unique certificate (and the rest of the configuration). If both Apache Server and browser support SNI, then the hostname is included in the original SSL request, and the web server can select the correct SSL virtual host.
The client browser must also support SNI. Here are some browsers that do:

  • Mozilla Firefox 2.0 or later
  • Opera 8.0 or later (with TLS 1.1 enabled)
  • Internet Explorer 7.0 or later (on Vista or higher, does not work on XP)
  • Google Chrome (Vista or higher. XP on Chrome 6 or newer. Mac OS X 10.5.7 or higher on Chrome 5.0.342.1 or newer)
  • Safari 3.2.1 or later (on Mac OS X 10.5.6 and Windows Vista or higher)

IBM HTTP Server for i support large file

IBM HTTP Server for i supports large file on i 7.1 will be released in the late of Dec. Here we create an article about the overview of the feature. If you have third-party HTTP Server plug-in or are WebSphere Application Server user, especially it's associated with a HTTP Server, strongly recommend you to follow the steps in the article to make your Web solution work correctly with large file support enabled HTTP Server on i 7.1.

IBM HTTP Server for i - Large File Support Overview

New DG1 features are coming

IBM Web Administration for i GUI interface has supported the creating and general management of application servers for many years.Before you created any WebSphere Application Servers you were required to follow the manual install instructions for getting that product on your IBM i.This Install support has now been added to the Web Admin GUI interface. Supports for WebSphere Application Server installation and IBM HTTP Server for i supports large file will be released in December.

IBM Web Administration for i supports WebSphere Application Server Installation

WebSphere Application Server V8.0, V8.5 and higher version can now be installed and managed by the IBM Web Administration GUI interface. Starting in V8.0 of the application server, the install support was switched to use the IBM Installation Manager (IM) tooling. This new tooling provides a solid install platform but on IBM i there is no GUI interface. To install the WebSphere Application Server installation, you need to prepare the command line or response file. Since IM has a robust scripting interface the IBM Web Administration for i is providing a GUI interface for IM to support following functions:

  • Install a new WebSphere Application Server installation
  • Update an existing installation with interim fixes or fix pack
  • Uninstall a WebSphere Application Server installation
  • View the installed interim fixes
  • Delete the interim fixes from the installation

Using the GUI interface of IBM Web Administration for i, you can easily and efficiently install and manage your WebSphere Application Server on IBM i platform.

This feature will be included in DG1 Group PTF SF99115 level 28 and SF99368 level 16.


IBM HTTP Server for i support large file

Currently we are working on a new requirement - HTTP Server large file (>2GB) support on i 7.1. We recompile HTTP Server with macro _LARGE_Files to allow HTTP Server to handles files larger than 2GB. With this new feature, all IBM i HTTP server plugin modules need to be recompile with the same macro too in order to work with the large support HTTP server. We have recompiled and shipped the large file support IAS/IWS plugin module(/QSYS.LIB/QHTTPSVR.LIB/QLWIIHSMOD.SRVPGM) and Domino plugin module. WebSphere Application Server plugin module(/qsys.lib/qwasxxv.lib/QSVTAP22LF.srvpgm) has also been recompiled by WebSphere Application Server team and will be integrated in the WebSphere Application Server fix packs: 6.1.0.45, 7.0.0.25, 8.0.0.5 and 8.5.0.1. If you are using the WebSphere Application Server you need to ensure you are at this specified fix pack to ensure you do not encounter issues.

Please note, the HTTP server configuration file will be automatically updated to use the new WebSphere Application Server and Domino plugin files where is applies when the HTTP Server is start. Users should not be effected by this update unless they have their own user written plugin modules. If any users have their own Apache modules, these user written Modules will be required to be re-compiled with this updated Macro. For users that have no user Apache modules, this change will have no effect.

The recompilation will change one of the most commonly used struct request_rec defined in httpd.h because it has many fields with the type apr_off_t. Based on our tests, our testing plugin can not work until we recompile it accordingly. In order to support this change, we strongly recommend all apache plugins and third-party modules to be checked by following below two steps:

(1) Review your apache plugin code to see if you ever hard coded any apr_off_t members to int when using members of struct request_rec. For example, if you are using the member bytes_sent and the below code snippet sample is not correct

void functionXXX(request_rec* r){
int size = r->bytes_sent;

}

The correct should be

void functionXXX(request_rec* r){
apr_off_t size = r->bytes_sent;
}

Please check and update your code to use the exact the same data type defined in the httpd.h rather than hard coded them to int or other data type.

(2) After step 1, your apache plugin also needs to be recompiled with the marco _LARGE_FILES to ensure your modules still work correctly with the large file support HTTP server.

This feature will be include in DG1 Group PTF SF99368 level 16.

IBM HTTP Server for i support group profile for access file

Previously, if customers want to add some users into one authentication list, they have to create a text file and write each member name one by one. Obviously this solution does not take advantages of IBM i group profile. So it is very inefficient especially when you have to add hundreds of members into one group.

This new feature allows customer to assign one IBM i group profile name as a member of one HTTP group. Essentially all the members of this IBM i group profile will be collected and added into that HTTP group. Now the management of group authentication list becomes more convenient and flexible for customers.

Below charts illustrated the differences brought by the new solution from customers' perspective. The GRP1 in dark red is an existing IBM i group profile. GRP1 contains 4 members: USER A/B/C/D. The new feature allows customer to add these 4 users into the authentication list by simply assigning the group profile name GRP1.

image-20200117111122-1

The new feature requires no directive changes in httpd.conf file. It only adds one key word %% in the HTTP group configuration file. When the server read such a key word, it will treat this name as a IBM i group profile name and search for all its members on i. Then all its members will be added into the authentication list along with other members.

I have to clarify that the GROUPA in "Require group GROUPA" is a HTTP group which will be generated when server start up. While the name of this new feature "Group Profile Access List" means the group on IBM i, which is GRP1 in above charts. One HTTP group can contain more than one IBM i group profiles as members. For example,

GROUPA: %GRP1% USER3 %GRP2% USER4
