rlogin(1C)							    rlogin(1C)

NAME    [Toc]    [Back]

     rlogin - remote login

SYNOPSIS    [Toc]    [Back]

     rlogin rhost [ -l username	] [ -ec	] [ -L ] [ -8 ]
     rlogin username@rhost [ -ec ] [ -L	] [ -8 ]

DESCRIPTION    [Toc]    [Back]

     rlogin connects your terminal on the current local	host system to the
     remote host system	rhost.	The remote username used is the	same as	your
     local username, unless you	specify	a different remote name	with the -l
     option or use the username@rhost format.

     The rlogin	arguments and options are:

     rhost	   The hostname	of the remote system.

     username	   The user ID to be used on the remote	system.

     -l	username   Specifies the user ID to be used on the remote system.

     -ec	   Specifies a different escape	character.  There is no	space
		   separating this option flag and the argument	character, c.

     -L		   Allows the rlogin session to	be run in litout mode.	A line
		   of the form ~. disconnects from the remote host, where ~ is
		   the escape character.  A line starting with ~! starts a
		   shell on the	IRIS.  Similarly, the line ~^Z (where ^Z,
		   <Ctrl-z>, is	the suspend character) suspends	the rlogin
		   session if you are using csh(1).

     -8		   Allows an 8-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.

     Each host has a file /etc/hosts.equiv that	contains a list	of remote
     hosts (equivalent hosts) with which it shares account names.  The
     hostnames must be the standard names as described in rsh(1C).  When you
     rlogin as the same	user on	an equivalent host, you	do not need to give a

     Each user can also	have a private equivalence list	in a file .rhosts in
     his home directory.  Each line in this file should	contain	an rhost and a
     username separated	by a space, which gives	an additional remote host
     where logins without passwords are	permitted.  If the originating user is
     not equivalent to the remote user,	the remote host	prompts	for a login
     and password as in	login(1).  To avoid some security problems, the
     .rhosts file must be owned	by either the remote user or root.

     Under Trusted IRIX/CMW, only the first field of the /etc/hosts.equiv and
     $HOME/.rhosts files is relevant to	the system.  The second	field is
     ignored as	a comment.  This behavior places a restriction on the rsh and

     rlogin programs, which do not allow unchallenged access (access without
     demanding a password) unless the remote user name and user	ID are exactly
     identical to the local user name and user ID.  If a different name	or
     user ID is	used, the user is prompted for a password that authenticates
     the user's	identity in the	usual manner.  The user	will also be prompted
     for a password if the MAC label of	the login session does not dominate
     the MAC label of the $HOME/.rhosts	file.  It is recommended that the
     $HOME/.rhosts file	be labeled such	that it	is dominated by	all other
     labels that the user can login with.

     The remote	terminal type is the same as your local	terminal type (as
     given in your TERM	environment variable).	The TERM value iris-ansi is
     converted to iris-ansi-net	when sent to the host.	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.

NOTES    [Toc]    [Back]

     In	a Trusted IRIX environment, a user can rlogin at a different MAC label
     (see dominance(5))	and/or capability set (see capability(4)) by
     specifying	the label and capability set after the username	at the login
     prompt. See login(1) for more details. However, the label and capability
     set can not be specified using command line options.

SEE ALSO    [Toc]    [Back]

     login(1), rsh(1C),	capability(4) hosts(4),	rhosts(4).  dominance(5)

BUGS    [Toc]    [Back]

     Only the TERM environment variable	is propagated.	The rlogin protocol
     should be extended	to propagate useful variables, such as DISPLAY.	 (Note
     that telnet(1C) is	able to	propagate environment variables.)
