NAMErlogin — remote login
SYNOPSISrlogin [ -468DEd][ -e char][ -i localname][ -l username] host
DESCRIPTIONThe rlogin utility starts a terminal session on a remote host host.
The standard Berkeley rhosts authorization mechanism is used.
The following options are available:
- Use IPv4 addresses only.
- Use IPv6 addresses only.
- Allow 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.
- Set the TCP_NODELAY socket option which can improve interactive response at the expense of increased network load.
- Stop any character from being recognized as an escape character. When used with the -8 option, this provides a completely transparent connection.
- Turn on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host.
- Allow 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.
- Allow the caller to specify a different local name to be used for authentication. This option is restricted to processes with uid 0.
- Specify a different username for the remote login. If this option is not specified, your local username will be used.
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 session, 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.
ENVIRONMENTThe following environment variable is utilized by rlogin:
- Determines the user's terminal type.
- $HOME /.rhosts

HISTORYThe rlogin command appeared in 4.2BSD.
IPv6 support was added by WIDE/KAME project.
BUGSThe rlogin utility will be replaced by telnet(1) in the near future.
More of the environment should be propagated.
