- _y_p_p_u_s_h copies a new version of the specified NIS map from the master NIS
- server to the slave NIS servers. It is normally run only on the master
- server by _y_p_m_a_k_e(1M) after the master databases are changed. It first
- constructs a list of NIS server hosts by reading the _y_p_s_e_r_v_e_r_s map within
- the _d_o_m_a_i_n. Keys within the _y_p_s_e_r_v_e_r_s map are the hostnames of the
- domain's NIS servers.
-
- A ``transfer map'' request is sent to the NIS server at each host, along
- with the information needed by the transfer agent (the program which
- actually moves the map) to call back the _y_p_p_u_s_h. When the attempt has
- completed (successfully or not), and the transfer agent has sent _y_p_p_u_s_h a
- status message, the results may be printed to stdout. Messages are also
- printed when a transfer is not possible; for instance when the request
- message is undeliverable, or when the timeout period on responses has
- expired.
-
- Refer to _y_p_f_i_l_e_s(4) and _y_p_s_e_r_v(1M) for an overview of NIS.

- ----dddd _d_o_m_a_i_n Specify a _d_o_m_a_i_n.
-
- ----vvvv Verbose. This causes messages to be printed when each server
- is called, and for each response. If this flag is omitted,
- only error messages are printed.

- In the current implementation (version 2 NIS protocol), the transfer
- agent is _y_p_x_f_r, which is started by the _y_p_s_e_r_v program. If _y_p_p_u_s_h
- detects that it is speaking to a version 1 NIS protocol server, it uses
- the older protocol, sending a version 1 YPPROC_GET request and issues a
- message to that effect. Unfortunately, there is no way of knowing if or
- when the map transfer is performed for version 1 servers. _y_p_p_u_s_h prints
- a message saying that an "old-style" message has been sent. The system
- administrator should later check to see that the transfer has actually
- taken place.
