- _d_g_l_d is the server for programs performing remote graphics with the
- Graphics Libary or for programs linked with the Distributed Graphics
- Library. The server provides both a subprocess graphics facility and a
- networked graphics facility. _d_g_l_d is started either by _i_n_e_t_d(1M) or by
- _d_n_s_e_r_v_e_r.
-
- TCP socket connections are serviced by _i_n_e_t_d. _i_n_e_t_d listens for
- connections on the port indicated in the ``sgi-dgl'' service
- specification; see _s_e_r_v_i_c_e_s(4). When a connection is found, _d_g_l_d is
- started as specified by the file /_u_s_r/_e_t_c/_i_n_e_t_d._c_o_n_f and given the
- socket. When using the Graphics Library, authentication is performed by
- the X server via the same mechanisms as for X clients. When using the
- Distributed Graphics Library, authentication is performed using
- _r_u_s_e_r_o_k(3N) in the same manner as _r_s_h_d and the server process's group and
- user id are changed accordingly.
-
- DECnet connections are serviced by _d_n_s_e_r_v_e_r, which listens for
- connections for an object named ``DGLD''. When a valid connection is
- established, _d_g_l_d is started as specified in /_u_s_r/_e_t_c/_d_n/_s_e_r_v_e_r_s._r_e_g and
- given the connection. Although a valid username and password is necessary
- to establish the connection, authentication using _r_u_s_e_r_o_k(3N) is still
- performed.

- The following options are supported:
-
- ----dddd Sets the highest debugging level.
-
- ----IIII Informs the graphics server that it was started from a network
- server process, that is, _i_n_e_t_d(1M) or _d_n_s_e_r_v_e_r, and enables
- output of all _d_g_l_d-originated error messages to the system log
- maintained by _s_y_s_l_o_g_d(1M).
-
- ----MMMM Disables all message output.
-
- ----DDDD _d_e_b_u_g_l_e_v_e_l
- Sets the level of debugging messages, ranging from 0 (lowest)
- to 4 (highest), to be reported when debugging applications
- linked with the Distributed Graphics Library.
-
- ----mmmm _m_s_g_f_i_l_e
- Writes debugging and error messages to _m_s_g_f_i_l_e.

-
- ----pppp _p_o_r_t Sets the port number used for a TCP socket connection.

- Normally operation produces no diagnostic output unless an error occurs.
- All error messages are output to ssssttttddddeeeerrrrrrrr unless otherwise redirected with
- the ----mmmm option. When _d_g_l_d is started from _i_n_e_t_d or _d_n_s_e_r_v_e_r both the ----MMMM
- and ----IIII options are given.
