Automatic map downloads
Should already work without configuration. You can however use the following cvars for further tuning (see xonotic.org/tools/cacs for more up-to-date information):
-
cl_curl_enabled: download support enabled (master switch) -
cl_curl_maxdownloads: maximum number of downloads at once -
cl_curl_maxspeed: maximum total speed in KiB/s
Downloaded packages end up in Xonotic/data/dlcache/ or
~/.xonotic/data/dlcache/ and are only used till you exit Xonotic.
If you want to play them localy or use them to setup a server of your
own you can "accept" the packages by moving it one level up - right
next to your config.cfg.
You should regularly clean up your cache to save space and make the maps you really want available from the menu.
First of all, you need a HTTP or FTP server to host your PK3s. You can either use some web space provider, or set up your own. For this, use any FTP or HTTP server software you want (HTTP: lighttpd, Apache, thttpd; FTP: Filezilla, vsftpd). HTTP is to be preferred because it works better for firewalled players.
On the server, you need to set up where to download the PK3s of the maps you are running. You can either use the cvar:
-
sv_curl_defaulturldefault download URL
to set it to some site, or put a file named "curl_urls.txt" in the data directory of the following format:
pattern url
pattern url
pattern url
...
where always the first wildcard pattern match is taken.
data* -
strale* http://stralemaps.invalid/
* http://all.the.other.stuff.invalid/id/here.php?pak=
foo* http://wont.get.here.invalid/
The pk3 name will be appended to the URL by DarkPlaces. Note that you NEED to append a trailing slash if you refer to a directory. If you specify a "-" as URL, the package will not be offered for download.
Note: HTTPS downloads are not supported for Xonotic Windows Clients! It works for the Linux client but you probably want to serve all players so it is advised to use http:// in sv_curl_defaulturl or curl_urls.txt.
Some Apache config snippet for the <VirtualHost> to allow for Xonotic Clients to use HTTP while all other traffic get redirected to HTTPS would be:
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^Xonotic
RewriteRule ^ - [END]
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}$1 [R=301,L]More Information about the Referer:
The Referer is always set to dp://serverhost:serverport/, the User-Agent always starts with "Xonotic". Look at this sample log line:
141.2.16.3 - - [06/Jun/2006:19:43:14 +0000] "GET /~polzer/temp/nexmaps.php?filename=o-fun.pk3 HTTP/1.1" 302 - "dp://141.2.16.3:26000/" "Xonotic Linux 21:26:17 Jun 6 2006"
If you want to set up a redirection service, here is a sample PHP code for you to start from:
<?
function findmap($filename)
{
# insert your database query or whatever you want here
if($filename == "foo.pk3")
return "http://barserver.invalid/foo.pk3";
return FALSE;
}
function bailout($code, $title, $message)
{
header("HTTP/1.1 $code $title");
echo "<html><title>$title</title><h1>$title</h1>$message</html>";
exit(0);
}
$filename = $_GET['filename'];
$useragent = getenv("HTTP_USER_AGENT");
if(strpos($useragent, "Xonotic ") !== 0)
bailout(403, "Forbidden", "You're not a Xonotic client.");
$url = findmap($filename);
if(!$url)
bailout(404, "Not Found", "Well... try another file name?");
header("HTTP/1.1 302 Moved Temporarily");
header("Location: $url");
?>
