netgroup - list of network groups
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
_N_e_t_g_r_o_u_p defines network-wide groups, used for permission checking when
doing remote mounts, remote logins, and remote shells. For remote
mounts, the information in _n_e_t_g_r_o_u_p is used to classify machines; for
remote logins and remote shells, it is used to classify users. Each line
of the _n_e_t_g_r_o_u_p file defines a group and has the format
groupname member1 member2 ....
where member_i is either another group name, or a triple:
(hostname, username, domainname)
hostname: The ``preferred'' name of the client host, the host
from which the _r_l_o_g_i_n(1C) or _r_s_h(1C) command is
invoked. Note that the preferred name is the first
name given to that host in the /_e_t_c/_h_o_s_t_s file.
The second and later names are the _a_l_i_a_s_e_s for that
preferred name. The preferred name is commonly the
fully-qualified ``domain-style'' name.
username: This is the simple user name string.
domainname: This is the name of the domain of the _s_e_r_v_e_r
system, not the client system.
Any of three fields can be empty, in which case it signifies a wild card.
Thus
universal (,,)
defines a group to which everyone belongs. Field names that begin with
something other than a letter, digit or underscore (such as ``-'') work
in precisely the opposite fashion. For example, consider the following
entries:
justmachines (analytica,-,sun)
justpeople (-,babbage,sun)
The machine _a_n_a_l_y_t_i_c_a belongs to the group _j_u_s_t_m_a_c_h_i_n_e_s in the domain
_s_u_n, but no users belong to it. Similarly, the user _b_a_b_b_a_g_e belongs to
the group _j_u_s_t_p_e_o_p_l_e in the domain _s_u_n, but no machines belong to it.
CCCCAAAAVVVVEEEEAAAATTTTSSSS
The netgroup data is used only when the nnnnssssdddd((((1111MMMM)))) daemon is running. It is
supported in any of the protocol libries included with Irix, but only one
protocol may be used. Listing multiple protocols on the netgroups line
in nnnnsssssssswwwwiiiittttcccchhhh....ccccoooonnnnffff((((4444)))) is not well defined.
