+pam_access — PAM module for logdaemon style login access control + +━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ + +DESCRIPTION + +The pam_access PAM module is mainly for access management. It provides +logdaemon style login access control based on login names, host or domain +names, internet addresses or network numbers, or on terminal line names in case +of non-networked logins. + +By default rules for access management are taken from config file /etc/security +/access.conf if you don't specify another file. + +If Linux PAM is compiled with audit support the module will report when it +denies access based on origin (host or tty). + +OPTIONS + +accessfile=/path/to/access.conf + + Indicate an alternative access.conf style configuration file to override + the default. This can be useful when different services need different + access lists. + +debug + + A lot of debug information is printed with syslog(3). + +noaudit + + Do not report logins from disallowed hosts and ttys to the audit subsystem. + +fieldsep=separators + + This option modifies the field separator character that pam_access will + recognize when parsing the access configuration file. For example: fieldsep + =| will cause the default `:' character to be treated as part of a field + value and `|' becomes the field separator. Doing this may be useful in + conjunction with a system that wants to use pam_access with X based + applications, since the PAM_TTY item is likely to be of the form + "hostname:0" which includes a `:' character in its value. But you should + not need this. + +listsep=separators + + This option modifies the list separator character that pam_access will + recognize when parsing the access configuration file. For example: listsep + =, will cause the default ` ' (space) and `\t' (tab) characters to be + treated as part of a list element value and `,' becomes the only list + element separator. Doing this may be useful on a system with group + information obtained from a Windows domain, where the default built-in + groups "Domain Users", "Domain Admins" contain a space. + +nodefgroup + + User tokens which are not enclosed in parentheses will not be matched + against the group database. The backwards compatible default is to try the + group database match even for tokens not enclosed in parentheses. + +EXAMPLES + +These are some example lines which might be specified in /etc/security/ +access.conf. + +User root should be allowed to get access via cron, X11 terminal :0, tty1, ..., +tty5, tty6. + ++ : root : crond :0 tty1 tty2 tty3 tty4 tty5 tty6 + +User root should be allowed to get access from hosts which own the IPv4 +addresses.
