NAME <\/a> <\/h2>\n

pam_nologin \u2212 Prevent non\u2212root users from login<\/p>\n

SYNOPSIS <\/a> <\/h2>\n\n\n
<\/td>\n\n

pam_nologin.so<\/b> [file=\/path\/nologin<\/i>] [successok]<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

pam_nologin is a PAM module that prevents users from logging into the system when \/var\/run\/nologin or \/etc\/nologin exists. The contents of the file are displayed to the user. The pam_nologin module has no effect on the root user’s ability to log in.<\/p>\n

OPTIONS <\/a> <\/h2>\n

file=<\/b>\/path\/nologin<\/i><\/p>\n

Use this file instead the default \/var\/run\/nologin or \/etc\/nologin.<\/p>\n

successok<\/b><\/p>\n

Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE.<\/p>\n

MODULE TYPES PROVIDED <\/a> <\/h2>\n

The auth<\/b> and acct<\/b> module types are provided.<\/p>\n

RETURN VALUES <\/a> <\/h2>\n

PAM_AUTH_ERR<\/p>\n

The user is not root and \/etc\/nologin exists, so the user is not permitted to log in.<\/p>\n

PAM_BUF_ERR<\/p>\n

Memory buffer error.<\/p>\n

PAM_IGNORE<\/p>\n

This is the default return value.<\/p>\n

PAM_SUCCESS<\/p>\n

Success: either the user is root or the nologin file does not exist.<\/p>\n

PAM_USER_UNKNOWN<\/p>\n

User not known to the underlying authentication module.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

The suggested usage for \/etc\/pam.d\/login is:<\/p>\n

auth required pam_nologin.so<\/p>\n

NOTES <\/a> <\/h2>\n

In order to make this module effective, all login methods should be secured by it. It should be used as a required<\/i> method listed before any sufficient<\/i> methods in order to get standard Unix nologin semantics. Note, the use of successok<\/b> module argument causes the module to return PAM_SUCCESS<\/i> and as such would break such a configuration \u2212 failing sufficient<\/i> modules would lead to a successful login because the nologin module succeeded<\/i>.<\/p>\n
