rshd

RSHD(8) 						    BSD System Manager's Manual 						   RSHD(8)

NAME

     rshd -- remote shell server

SYNOPSIS

     rshd [-aiklnvxPL] [-p port]

DESCRIPTION

     rshd is the server for the rsh(1) program. It provides an authenticated remote command execution service.	Supported options are:

     -n, --no-keepalive
	     Disables keep-alive messages.  Keep-alives are packets sent at certain intervals to make sure that the client is still there, even
	     when it doesn't send any data.

     -k, --kerberos
	     Assume that clients connecting to this server will use some form of Kerberos authentication. See the EXAMPLES section for a sample
	     inetd.conf(5) configuration.

     -x, --encrypt
	     For Kerberos 4 this means that the connections are encrypted. Kerberos 5 can negotiate encryption even without this option, but if
	     it's present rshd will deny unencrypted connections. This option implies -k.

     -v, --vacuous
	     If the connecting client does not use any Kerberised authentication, print a message that complains about this fact, and exit. This
	     is helpful if you want to move away from old port-based authentication.

     -P      When using the AFS filesystem, users' authentication tokens are put in something called a PAG (Process Authentication Group). Multi-
	     ple processes can share a PAG, but normally each login session has its own PAG. This option disables the setpag() call, so all tokens
	     will be put in the default (uid-based) PAG, making it possible to share tokens between sessions. This is only useful in peculiar
	     environments, such as some batch systems.

     -i, --no-inetd
	     The -i option will cause rshd to create a socket, instead of assuming that its stdin came from inetd(8).  This is mostly useful for
	     debugging.

     -p port, --port=port
	     Port to use with -i.

     -a      This flag is for backwards compatibility only.

     -L      This flag enables logging of connections to syslogd(8).  This option is always on in this implementation.

FILES

     /etc/hosts.equiv
     ~/.rhosts

EXAMPLES

     The following can be used to enable Kerberised rsh in inetd.cond(5), while disabling non-Kerberised connections:

     shell   stream  tcp  nowait  root	/usr/libexec/rshd  rshd -v
     kshell  stream  tcp  nowait  root	/usr/libexec/rshd  rshd -k
     ekshell stream  tcp  nowait  root	/usr/libexec/rshd  rshd -kx

SEE ALSO

     rsh(1), iruserok(3)

HISTORY

     The rshd command appeared in 4.2BSD.

AUTHORS

     This implementation of rshd was written as part of the Heimdal Kerberos 5 implementation.
