With no flags, the program displays the current ARP entry for _h_o_s_t_n_a_m_e. The host may be specified by name or by number, using Internet dot nota- tion. Available options: --aa The program displays all of the current ARP entries. --dd A super-user may delete an entry for the host called _h_o_s_t_n_a_m_e with the --dd flag. --ss _h_o_s_t_n_a_m_e _e_t_h_e_r___a_d_d_r Create an ARP entry for the host called _h_o_s_t_n_a_m_e with the Ether- net address _e_t_h_e_r___a_d_d_r. The Ethernet address is given as six hex bytes separated by colons. The entry will be permanent unless the word _t_e_m_p is given in the command. If the word _p_u_b is given, the entry will be "published"; i.e., this system will act as an ARP server, responding to requests for _h_o_s_t_n_a_m_e even though the host address is not its own. The word _t_r_a_i_l indicates that trailer encapsulations may be sent to this host. --ff Causes the file _f_i_l_e_n_a_m_e to be read and multiple entries to be set in the ARP tables. Entries in the file should be of the form _h_o_s_t_n_a_m_e _e_t_h_e_r___a_d_d_r [_t_e_m_p] [_p_u_b] [_t_r_a_i_l] with argument meanings as given above.
