How to find Installed IBM HTTP Server Version & Architecture?

Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

HTTP Server by IBM is based on Apache HTTP, which can be installed on AIX, Linux, Solaris, Windows, HP-UX or z/OS.

There is four major version of IHS available.

Knowing which version is installed on your server is essential for technical stack auditing and ensuring you have the latest version.

Here are two ways to find out the installed IBM HTTP Server version and Architecture.

Find through versionInfo.sh

Probably the most reliable and best way to find the version installed on the server.

  • Log in to the IBM HTTP Server
  • Go to the path it’s installed
  • Go to the bin folder and execute below file
[root@localhost bin]# ./versionInfo.sh | grep Version

WVER0012I: VersionInfo reporter version 1.15.1.48, dated 2/8/12

Version Directory       /opt/IBM/HTTPServer/properties/version

Version               8.5.5.9

Installed Features   IBM HTTP Server 64-bit with Java, Version 6

[root@localhost bin]#

To know the architecture, you can use below grep

[root@localhost bin]# ./versionInfo.sh | grep Arch

Architecture         x86-64 (64 bit)

[root@localhost bin]#

So now you know it’s 8.5.5.9 with 64 bit in above example.

Check the IHS version through log file

If you are not into production support then you may not have the server access to execute versionInfo.sh file to see the version. In this situation, assuming you have access to the log file you can use following technique.

Login into IBM HTTP Server and access the path where IHS logs are generated

View the error_log file and look at the startup line, it should read the version under notice as shown below.

[Mon May 02 06:13:54 2016] [notice] IBM_HTTP_Server/8.5.5.9 (Unix) configured -- resuming normal operations

Note: log file will not have the architecture details.

If you are looking to find out the IBM HTTP Server historical versions on the server then you can use historyInfo.sh.

[root@localhost bin]# ./historyInfo.sh
