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_rhosts — The rhosts PAM module
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
DESCRIPTION
This module performs the standard network authentication for services, as used
by traditional implementations of rlogin and rsh etc.
The authentication mechanism of this module is based on the contents of two
files; /etc/hosts.equiv (or and ~/.rhosts. Firstly, hosts listed in the former
file are treated as equivalent to the localhost. Secondly, entries in the
user's own copy of the latter file is used to map "remote-host remote-user"
pairs to that user's account on the current host. Access is granted to the user
if their host is present in /etc/hosts.equiv and their remote account is
identical to their local one, or if their remote account has an entry in their
personal configuration file.
The module authenticates a remote user (internally specified by the item
PAM_RUSER connecting from the remote host (internally specified by the item
PAM_RHOST). Accordingly, for applications to be compatible this authentication
module they must set these items prior to calling pam_authenticate(). The
module is not capable of independently probing the network connection for such
information.
OPTIONS
debug
Print debug information.
silent
Don't print informative messages.
superuser=account
Handle account as root.
EXAMPLES
To grant a remote user access by /etc/hosts.equiv or .rhosts for rsh add the
following lines to /etc/pam.d/rsh:
#%PAM-1.0
#
auth required pam_rhosts.so
auth required pam_nologin.so
auth required pam_env.so
