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。 .

pam_motd -- Display the motd file

   --------------------------------------------------------------------------

DESCRIPTION

   pam_motd is a PAM module that can be used to display arbitrary motd
   (message of the day) files after a successful login. By default, pam_motd
   shows files in the following locations:

   /etc/motd
   /run/motd
   /usr/lib/motd
   /etc/motd.d/
   /run/motd.d/
   /usr/lib/motd.d/

   Each message size is limited to 64KB.

   If /etc/motd does not exist, then /run/motd is shown. If /run/motd does
   not exist, then /usr/lib/motd is shown.

   Similar overriding behavior applies to the directories. Files in
   /etc/motd.d/ override files with the same name in /run/motd.d/ and
   /usr/lib/motd.d/. Files in /run/motd.d/ override files with the same name
   in /usr/lib/motd.d/.

   Files in the directories listed above are displayed in lexicographic order
   by name. Moreover, the files are filtered by reading them with the
   credentials of the target user authenticating on the system.

   To silence a message, a symbolic link with target /dev/null may be placed
   in /etc/motd.d with the same filename as the message to be silenced.
   Example: Creating a symbolic link as follows silences
   /usr/lib/motd.d/my_motd.

   ln -s /dev/null /etc/motd.d/my_motd

OPTIONS

   motd=/path/filename

           The /path/filename file is displayed as message of the day.
           Multiple paths to try can be specified as a colon-separated list.
           By default this option is set to
           /etc/motd:/run/motd:/usr/lib/motd.

   motd_dir=/path/dirname.d

           The /path/dirname.d directory is scanned and each file contained
           inside of it is displayed. Multiple directories to scan can be
           specified as a colon-separated list. By default this option is set
           to /etc/motd.d:/run/motd.d:/usr/lib/motd.d.

   When no options are given, the default behavior applies for both options.
   Specifying either option (or both) will disable the default behavior for
   both options.

EXAMPLES

   The suggested usage for /etc/pam.d/login is:

 session  optional  pam_motd.so


   To use a motd file from a different location:

 session  optional  pam_motd.so motd=/elsewhere/motd


   To use a motd file from elsewhere, along with a corresponding .d
   directory:

 session  optional  pam_motd.so motd=/elsewhere/motd motd_dir=/elsewhere/motd.d
