+.SH "NAME"
+access.conf \- the login access control table file
+.SH "DESCRIPTION"
+.PP
+The
+\fI/etc/security/access.conf\fR
+file specifies (\fIuser\fR,
+\fIhost\fR), (\fIuser\fR,
+\fInetwork/netmask\fR) or (\fIuser\fR,
+\fItty\fR) combinations for which a login will be either accepted or refused.
+.PP
+When someone logs in, the file
+\fIaccess.conf\fR
+is scanned for the first entry that matches the (\fIuser\fR,
+\fIhost\fR) or (\fIuser\fR,
+\fInetwork/netmask\fR) combination, or, in case of non\-networked logins, the first entry that matches the (\fIuser\fR,
+\fItty\fR) combination. The permissions field of that table entry determines whether the login will be accepted or refused.
+.PP
+Each line of the login access control table has three fields separated by a ":" character (colon):
+.PP
+
+\fIpermission\fR:\fIusers\fR:\fIorigins\fR
+.PP
+The first field, the
+\fIpermission\fR
+field, can be either a "\fI+\fR" character (plus) for access granted or a "\fI\-\fR" character (minus) for access denied.
+.PP
+The second field, the
+\fIusers\fR
+field, should be a list of one or more login names, group names, or
+\fIALL\fR
+(which always matches).
+.PP
+The third field, the
+\fIorigins\fR
+field, should be a list of one or more tty names (for non\-networked logins), host names, domain names (begin with "."), host addresses, internet network numbers (end with "."), internet network addresses with network mask (where network mask can be a decimal number or an internet address also),
+\fIALL\fR
+(which always matches) or
+\fILOCAL\fR
+(which matches any string that does not contain a "." character). If supported by the system you can use
+\fI@netgroupname\fR
+in host or user patterns.
+.PP
+The
+\fIexcept\fR
+operator makes it possible to write very compact rules.
+.PP
+The group file is searched only when a name does not match that of the logged\-in user. Only groups are matched in which users are explicitly listed. However the PAM module does not look at the primary group id of a user.
+.PP
+The "\fI#\fR" character at start of line (no space at front) can be used to mark this line as a comment line.
+.SH "EXAMPLES"
+.PP
+These are some example lines which might be specified in
+\fI/etc/security/access.conf\fR.
+.PP
+User
+\fIroot\fR
+should be allowed to get access via
+\fIcron\fR, X11 terminal
+\fI:0\fR,
+\fItty1\fR, ...,
+\fItty5\fR,
+\fItty6\fR.
+.PP
++ : root : crond :0 tty1 tty2 tty3 tty4 tty5 tty6
+.PP
+User
+\fIroot\fR
+should be allowed to get access from hosts which own the IPv4 addresses. This does not mean that the connection have to be a IPv4 one, a IPv6 connection from a host with one of this IPv4 addresses does work, too.
+.PP
++ : root : 192.168.200.1 192.168.200.4 192.168.200.9
+.PP
++ : root : 127.0.0.1
+.PP
+User
+\fIroot\fR
+should get access from network
+192.168.201.
+where the term will be evaluated by string matching. But it might be better to use network/netmask instead. The same meaning of
+192.168.201.
+is
+\fI192.168.201.0/24\fR
+or
+\fI192.168.201.0/255.255.255.0\fR.

+.PP
+\- : root : ALL
+.PP
+User
+\fIfoo\fR
+and members of netgroup
+\fIadmins\fR
+should be allowed to get access from all sources. This will only work if netgroup service is available.
+.PP

+.PP
+User

+should get access from IPv6 host address.
+.PP
++ : john foo : 2001:4ca0:0:101::1
+.PP
+User
+\fIjohn\fR
+should get access from IPv6 net/mask.
+.PP
