Linux – mod_rpaf not recognising RPAFheader setting

apache-2.2linuxmod-rpafvarnish

After installing mod_rpaf, I set my config file (/etc/apache2/mods-available/rpaf.conf) as follows:

<IfModule mod_rpaf.c>
    RPAFenable On
    RPAFsethostname On
    RPAFproxy_ips 127.0.0.1
    RPAFheader X-Real-IP
</IfModule>

However, now when I restart apache2 I get an error:

Invalid command 'RPAFheader', perhaps misspelled or defined by a
module not included in the server configuration

Removing the RPAFheader line resolves the problem, but I really need this setting. Does anyone have any ideas?

Ubuntu 10.04 includes version 0.5 of mod_rpaf but the RPAFheader command was added in version 0.6. Ubuntu 12.04 comes with mod_rpaf version 0.6 for some architectures and 0.5 for others.

Ubuntu 12.04 also contains a bug which means you have to change

<IfModule mod_rpaf.c>

into

<IfModule mod_rpaf-2.0.c>

before it will work.

Note that with Apache 2.4, mod_rpaf is no longer needed and is replaced by mod_remoteip.
