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_exec — PAM module which calls an external command

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

DESCRIPTION

pam_exec is a PAM module that can be used to run an external command.

The child's environment is set to the current PAM environment list, as returned
by pam_getenvlist(3) In addition, the following PAM items are exported as
environment variables: PAM_RHOST, PAM_RUSER, PAM_SERVICE, PAM_TTY, PAM_USER and
PAM_TYPE, which contains one of the module types: account, auth, password,
open_session and close_session.

Commands called by pam_exec need to be aware of that the user can have controll
over the environment.

OPTIONS

debug

    Print debug information.

expose_authtok

    During authentication the calling command can read the password from stdin
    (3). Only first PAM_MAX_RESP_SIZE bytes of a password are provided to the
    command.

log=file

    The output of the command is appended to file

type=type

    Only run the command if the module type matches the given type.

stdout

    Per default the output of the executed command is written to /dev/null.
    With this option, the stdout output of the executed command is redirected
    to the calling application. It's in the responsibility of this application
    what happens with the output. The log option is ignored.

quiet

    Per default pam_exec.so will echo the exit status of the external command
    if it fails. Specifying this option will suppress the message.

seteuid

    Per default pam_exec.so will execute the external command with the real
    user ID of the calling process. Specifying this option means the command is
    run with the effective user ID.

EXAMPLES

Add the following line to /etc/pam.d/passwd to rebuild the NIS database after
each local password change:

        password optional pam_exec.so seteuid /usr/bin/make -C /var/yp


This will execute the command

make -C /var/yp

with effective user ID.
