rlogin [-468dEn] [-e char] [-p port] username@host


rlogin starts a terminal session on a remote host host.

rlogin first attempts to use the standard Berkeley rhosts authorization mechanism. The options are as follows:

Use IPv4 addresses only.
Use IPv6 addresses only.
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’.
The -d option turns on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host.
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.
-e char
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.
-l username
the -l option specifies an alternate username for the remote login. If this option is not specified, your local username will be used.
Set the TCP_NODELAY socket option, which can improve interactive responsiveness at the possible downside of increased network load.
-p port
Uses the given port instead of the one assigned to the service “login”. May be given either as symbolic name or as number.

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 used by rlogin:
Determines the user's terminal type.


The rlogin command appeared in 4.2BSD.


More of the environment should be propagated.
