rlogin - remote login


rlogin [-8EKLdx] [-e char] [-l username] host


Rlogin starts a terminal session on a remote host host.

The standard Berkeley rhosts authorization mechanism is used. The options are as follows:

-8 The -8 option 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 .
-E The -E option stops any character from being recognized as an escape character. When used with the -8 option, this provides a completely transparent connection.
-L The -L option allows the rlogin session to be run in ‘‘litout’’ (see tty(4)) mode.
-d The -d option turns on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host.
-e The -e option allows user specification of the escape character, which is ‘‘~’’ by default. This specification may be as a literal character, or as an octal value in the form \nnn.

A line of the form ‘‘<escape char>.’’ disconnects from the remote host. Similarly, the line ‘‘<escape char>^Z’’ will suspend the rlogin session, and ‘‘<escape char><delayed-suspend char>’’ suspends the send portion of the rlogin, but allows output from the remote system. By default, the tilde (‘‘~’’) character is the escape character, and normally control-Y (‘‘^Y’’) is the delayed-suspend character.

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


The following environment variable is utilized by rlogin:
TERM Determines the user’s terminal type.



The rlogin command appeared in BSD 4.2 .


Rlogin will be replaced by telnet(1) in the near future.

More of the environment should be propagated.
