                      2: 
                      3: NNAAMMEE
                      4:      rrllooggiinn - remote login

                     10:      RRllooggiinn starts a terminal session on a remote host _h_o_s_t.
                     11: 
                     12:      RRllooggiinn first attempts to use the Kerberos authorization mechanism,
                     13:      described below.  If the remote host does not supporting Kerberos the
                     14:      standard Berkeley _r_h_o_s_t_s authorization mechanism is used.     The options
                     15:      are as follows:
                     16: 
                     17:      --88        The --88 option allows an eight-bit input data path at all times;
                     18:               otherwise parity bits are stripped except when the remote
                     19:               side's stop and start characters are other than ^S/^Q.  Eight-
                     20:               bit mode is the default.
                     21: 
                     22:      --KK        The --KK option turns off all Kerberos authentication.
                     23: 
                     24:      --LL        The --LL option allows the rlogin session to be run in ``litout''
                     25:               (see tty(4)) mode.
                     26: 
                     27:      --dd        The --dd option turns on socket debugging (see setsockopt(2)) on
                     28:               the TCP sockets used for communication with the remote host.
                     29: 
                     30:      --ee        By default, the tilde (``~'') character is the escape charac-
                     31:               ter.  The --ee option allows specification of a different escape
                     32:               character.
                     33: 
                     34:      --kk        The option requests rlogin to obtain tickets for the remote
                     35:               host in realm _r_e_a_l_m instead of the remote host's realm as
                     36:               determined by krb_realmofhost(3).
                     37: 
                     38:      --xx        The --xx option turns on DES encryption for all data passed via
                     39:               the rlogin session.  This may impact response time and CPU
                     40:               utilization, but provides increased security.
                     41: 
                     42:      A line of the form ``~.'' disconnects from the remote host, where ``~''
                     43:      is the escape character.  Similarly, the line ``~^Z'' will suspend the
                     44:      rrllooggiinn session.  Substitution of the delayed-suspend character (normally
                     45:      ^Y) for the suspend character suspends the send portion of the rlogin,
                     46:      but allows output from the remote system.
                     47: 
                     48:      All echoing takes place at the remote site, so that (except for delays)
                     49:      the rrllooggiinn is transparent.  Flow control via ^S/^Q and flushing of input
                     50:      and output on interrupts are handled properly.
                     51: 
                     52: KKEERRBBEERROOSS AAUUTTHHEENNTTIICCAATTIIOONN
                     53:      Each user may have a private authorization list in the file ._k_l_o_g_i_n in
                     54:      their home directory.  Each line in this file should contain a Kerberos
                     55:      principal name of the form _p_r_i_n_c_i_p_a_l._i_n_s_t_a_n_c_e@_r_e_a_l_m.  If the originating
                     56:      user is authenticated to one of the principals named in ._k_l_o_g_i_n, access
                     57:      is granted to the account.  The principal _a_c_c_o_u_n_t_n_a_m_e.@_l_o_c_a_l_r_e_a_l_m is
                     58:      granted access if there is no ._k_l_o_g_i_n file.  Otherwise a login and pass-
                     59:      word will be prompted for on the remote machine as in login(1).  To avoid
                     60:      certain security problems, the ._k_l_o_g_i_n file must be owned by the remote
                     61:      user.
                     62: 
                     63:      If Kerberos authentication fails, a warning message is printed and the
                     64:      standard Berkeley _r_l_o_g_i_n is used instead.
                     65: 
                     66: EENNVVIIRROONNMMEENNTT
                     67:      The following environment variable is utilized by rrllooggiinn:
                     68:      TERM      to find user's terminal type.
                     69: 
                     70: SSEEEE AALLSSOO
                     71:      rsh(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3)
                     72: 
                     73: HHIISSTTOORRYY
                     74:      RRllooggiinn appeared in 4.2 BSD.
                     75: 
                     76: BBUUGGSS
                     77:      RRllooggiinn will be replaced by telnet(1) in the near future.
                     78: 
                     79:      More of the environment should be propagated.
