晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

ABOUT
mod_ruid2 is a suexec module for apache 2.0, 2.2 and 2.4, based on mod_ruid and mod_suid2

-it runs only on linux because afaik only linux has implemented posix 1003.1e capabilities
-it has better performance than mod_suid2 because it doesn`t need to kill httpd children
 after one request. it makes use of kernel capabilites and after receiving a new request suids again.
-there are some security issues, for instance if attacker successfully exploits the httpd process,
 he can set effective capabilities and setuid to root. i recommend to use some security patch in kernel (grsec),
 or something..

-there are two main operation modes: stat and config
 1. config
 is default, you must define uid and gid. If no [ug]id is defined the default user and group are used.

 2. stat
 httpd setuid and setgid to uid and gid of requested filename(script)/directory
 this is good if you use mod_vhost_alias for virtual hosting

INSTALL
 1. download and install latest libcap from here
 2. run /apachedir/bin/apxs -a -i -l cap -c mod_ruid2.c
 3. configure httpd.conf
 4. restart apache

CONFIGURE OPTIONS:
 RMode config|stat (default is config)
 RUidGid user|#uid group|#gid - when RMode is config, set to this uid and gid

 RMinUidGid user|#uid group|#gid - when uid/gid is < than min uid/gid set to default uid/gid
 RDefaultUidGid user|#uid group|#gid

 RGroups group1 group2 - aditional groups set via setgroups
 @none - clear all previous defined groups.

 RDocumentChrRoot - Set chroot directory and the document root inside
