Re: Install guide for CentOS 4.2: msg#00230

A@H is CentOS 3.x. CentOS 4.x has as a default value for session.save_path /var/lib/php/session . You can change the value to /tmp in 4.x but I think the setting in 4.x reflects the fact that there is the potential to hijack sessions when /tmp is used.

(just want to throw out some general information about this for people who care to know)

Strictly speaking as a web developer, not related to asterisk/AAH/AMP stuff, basically the idea behind this is that /tmp is usually world-readable, and that if you have multiple clients hosting domains on a shared server, people from other domains can get session IDs by looking in /tmp, or even getting the conents of the session by reading those files. This is not an issue if everyone on the server is trusted (ie, everyone with access to /tmp), assuming that users can't somehow list or read /tmp from the webserver (such as through an unsecure application that allows specifying arbitrary paths in the url).

Back to the AMP point of view, you really shouldn't be using your [production] telephony server as a general hosting platform, and certainly not hosting for 3rd parties. So this is really a non-issue with respect to AMP/AAH, just something to keep in mind.
