Which version of mod * do I have installed?
From Brandonhutchinson.com
If for some reason mod_perl, mod_ssl, etc., were installed without package management and you do not know the version number, you can determine it using strings.
e.g., module directory of /usr/lib/apache
- mod_perl
$ strings /usr/lib/apache/libperl.so | grep mod_perl/ mod_perl/1.29
- mod_ssl
$ strings /usr/lib/apache/libssl.so | grep ^\$Id $Id: mod_ssl/2.8.22 $
