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_ftp — PAM module for anonymous access module

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

DESCRIPTION

pam_ftp is a PAM module which provides a pluggable anonymous ftp mode of
access.

This module intercepts the user's name and password. If the name is ftp or 
anonymous, the user's password is broken up at the @ delimiter into a PAM_RUSER
and a PAM_RHOST part; these pam-items being set accordingly. The username (
PAM_USER) is set to ftp. In this case the module succeeds. Alternatively, the
module sets the PAM_AUTHTOK item with the entered password and fails.

This module is not safe and easily spoofable.

OPTIONS

debug

    Print debug information.

ignore

    Pay no attention to the email address of the user (if supplied).

ftp=XXX,YYY,...

    Instead of ftp or anonymous, provide anonymous login to the comma separated
    list of users: XXX,YYY,.... Should the applicant enter one of these
    usernames the returned username is set to the first in the list: XXX.

EXAMPLES

Add the following line to /etc/pam.d/ftpd to handle ftp style anonymous login:

#
# ftpd; add ftp-specifics. These lines enable anonymous ftp over
#       standard UN*X access (the listfile entry blocks access to
#       users listed in /etc/ftpusers)
#
auth    sufficient  pam_ftp.so
auth    required    pam_unix.so use_first_pass
auth    required    pam_listfile.so \
           onerr=succeed item=user sense=deny file=/etc/ftpusers
