rlogin - remote login


     rlogin [-8EL] [-ec ] [-l username] hostname


     rlogin establishes a remote login session from your terminal
     to the remote machine named hostname.

     Hostnames are listed in the hosts  database,  which  may  be
     contained in the /etc/hosts and /etc/inet/ipnodes files, the
     Network Information Service (NIS) hosts  map,  the  Internet
     domain name server, or a combination of these. Each host has
     one official name (the first name in  the  database  entry),
     and  optionally one or more nicknames. Either official host-
     names or nicknames may be specified in hostname.

     Each remote machine may have a file  named  /etc/hosts.equiv
     containing  a list of trusted hostnames with which it shares
     usernames. Users with the same username on  both  the  local
     and  remote  machine  may rlogin from the machines listed in
     the remote machine's /etc/hosts.equiv file without supplying
     a  password.  Individual  users may set up a similar private
     equivalence list with the file .rhosts in their home  direc-
     tories.  Each  line in this file contains two names: a host-
     name and a username separated by a  space.  An  entry  in  a
     remote  user's  .rhosts file permits the user named username
     who is logged into hostname to log in to the remote  machine
     as the remote user without supplying a password. If the name
     of the local host is not found in the /etc/hosts.equiv  file
     on  the  remote machine, and the local username and hostname
     are not found in the remote user's .rhosts  file,  then  the
     remote  machine will prompt for a password. Hostnames listed
     in /etc/hosts.equiv and .rhosts files must be  the  official
     hostnames listed in the hosts database; nicknames may not be
     used in either of these files.

     For security reasons, the .rhosts  file  must  be  owned  by
     either the remote user or by root.

     The remote terminal type is the same as your local  terminal
     type (as given in your environment TERM variable).  The ter-
     minal 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 remote login is tran-
     sparent.  Flow  control  using  <CTRL-S>  and  <CTRL-Q>  and
     flushing of input and output on interrupts are handled prop-


     The following options are supported:

     -8    Pass eight-bit data across the net instead  of  seven-
           bit data.

     -ec   Specify a different escape character, c, for the  line
           used to disconnect from the remote host.

     -E    Stop any character from being recognized as an  escape

     -l username
           Specify a different username for the remote login.  If
           you  do  not use this option, the remote username used
           is the same as your local username.

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

  Escape Sequences
     Lines that you type which start with the tilde character are
     "escape  sequences"  (the  escape  character  can be changed
     using the -e option):

     ~.    Disconnect from the remote host. This is not the  same
           as a logout, because the local host breaks the connec-
           tion with no warning to the remote end.

     ~susp Suspend the login session (only if  you  are  using  a
           shell  with Job Control). susp is your "suspend" char-
           acter, usually <CTRL-Z>; see tty(1).

           Suspend the input half of the login, but  output  will
           still  be seen (only if you are using a shell with Job
           Control). dsusp is your "deferred suspend"  character,
           usually <CTRL-Y>; see tty(1).

           remote login session.

     The following message indicates that the machine is  in  the
     process of being shutdown and logins have been disabled:

     NO LOGINS: System going down in N minutes


     When a system is listed in hosts.equiv, its security must be
     as  good  as  local security.  One insecure system listed in
     hosts.equiv can compromise the security of the  entire  sys-

     The Network Information Service (NIS) was formerly known  as
     Sun  Yellow Pages (YP.) The functionality of the two remains
     the same; only the name has changed.

     This implementation can only use the TCP network service.
