Greetings, There are multiple ways to set up koha (packages, git, tarball), and there are multiple ways to set up apache (named virtual hosts or port-based). The packages instructions use Named Virtual Hosts. And because of the name difference, they can be on the same port. The git instructions, if you compare, use a port-based set up. Both are functional and correct. A named virtual hosts set up makes more sense for packages, particularly if you wish to put it on the internet, so people can put holds on books, and then come to the library to pick the books up. In the case of a git set up, it is a development set up. You are not likely to set it up on the internet, because the data is probably bogus or filled with problems, because of testing that has been done. There is no error. Cross-reference this to the canonical DEBIAN instructions: http://wiki.koha-community.org/wiki/Koha_3.8_on_Debian_Squeeze#Initial_Confi... You will see they are identical. This is correct. Do not change anything. Now to be fair, you can put any port other than 80. But it doesn’t make sense to go to: https://library-intra.framisdooby.org:8080/ and https://library.framisdooby.org/ A port change and a name change combined is just plain over-complicated. So, if you were going to be completely port-based, INTRAPORT="8080" # TCP listening port for the administration interface INTRAPREFIX="" # For administration interface URL: Prefix to be added to the instance name. INTRASUFFIX="" # For administration interface URL: Suffix to be added to the instance name. would make more sense. The point of each value is to give flexibility in the apache configuration. Hope this explains things a bit. GPML, Mark Tompsett
