RLOGIN(1)										RLOGIN(1)

       rlogin - remote login

       rlogin  rhost [-ec] [-8] [-c] [ -a] [-f] [-F] [-t termtype] [-n] [-7] [-PN | -PO] [-d] [-k
       realm] [-x] [-L] [-l username]

       Rlogin connects your terminal on the current local host system lhost to	the  remote  host
       system rhost.

       The  version built to use Kerberos authentication is very similar to the standard Berkeley
       rlogin(1), except that instead of the rhosts mechanism, it uses Kerberos authentication to
       determine the authorization to use a remote account.

       Each user may have a private authorization list in a file .k5login in his login directory.
       Each line in this file should contain a	Kerberos  principal  name  of  the  form  princi-
       pal/instance@realm.   If  the  originating  user is authenticated to one of the principals
       named in .k5login, access is granted to the account.  If there is no /.k5login  file,  the
       principal  will	be  granted  access  to the account according to the aname->lname mapping
       rules.  (See krb5_anadd(8) for more details.)  Otherwise a  login  and  password  will  be
       prompted  for  on the remote machine as in login(1).  To avoid some security problems, the
       .k5login file must be owned by the remote user.

       If there is some problem in marshaling the Kerberos authentication information,	an  error
       message	is  printed  and  the  standard  UCB  rlogin is executed in place of the Kerberos

       A line of the form ``~.'' disconnects from the remote host,  where  ``~''  is  the  escape
       character.   Similarly,	the  line ``~^Z'' (where ^Z, control-Z, is the suspend character)
       will suspend the rlogin session.  Substitution of the delayed-suspend character	(normally
       ^Y)  for  the suspend character suspends the send portion of the rlogin, but allows output
       from the remote system.

       The remote terminal type is the same as your local terminal type (as given in  your  envi-
       ronment	TERM  variable),  unless the -t option is specified (see below).  The terminal or
       window size is also copied to the remote system if the server  supports	the  option,  and
       changes in size are reflected as well.

       All  echoing  takes  place  at  the remote site, so that (except for delays) the rlogin is
       transparent.  Flow control via ^S and ^Q and flushing of input and  output  on  interrupts
       are handled properly.

       -8     allows  an  eight-bit  input  data  path	at  all  times; otherwise parity bits are
	      stripped except when the remote side's stop and start  characters  are  other  than
	      ^S/^Q.  Eight-bit mode is the default.

       -L     allows the rlogin session to be run in litout mode.

       -ec    sets  the escape character to c.	There is no space separating this option flag and
	      the new escape character.

       -c     require confirmation before disconnecting via ``~.''

       -a     force the remote machine to ask for a password by sending a  null  local	username.
	      This  option  has  no effect unless the standard UCB rlogin is executed in place of
	      the Kerberos rlogin (see above).

       -f     forward a copy of the local credentials to the remote system.

       -F     forward a forwardable copy of the local credentials to the remote system.

       -t termtype
	      replace the terminal type passed to the remote host with termtype.

       -n     prevent suspension of rlogin via ``~^Z'' or ``~^Y''.

       -7     force seven-bit transmissions.

       -d     turn on socket debugging (via setsockopt(2)) on the TCP sockets used for communica-
	      tion with the remote host.

       -k     request  rlogin to obtain tickets for the remote host in realm realm instead of the
	      remote host's realm as determined by krb_realmofhost(3).

       -x     turn on DES encryption for all data passed via the rlogin session.   This  signifi-
	      cantly reduces response time and significantly increases CPU utilization.


       -PO    Explicitly  request  new or old version of the Kerberos ``rcmd'' protocol.  The new
	      protocol avoids many security problems found in the old one, but is not interopera-
	      ble  with  older	servers.  (An "input/output error" and a closed connection is the
	      most likely result of attempting this combination.)  If neither  option  is  speci-
	      fied, some simple heuristics are used to guess which to try.

       rsh(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3), rlogin(1) [UCB version]

       ~/.k5login  (on	remote	host)  -  file	containing  Kerberos  principals that are allowed

       More of the environment should be propagated.
