NAME¶

mrlogin — munge authenticated remote login

SYNOPSIS¶

DESCRIPTION¶

Mrlogin is a modification of the rlogin command that uses munge authentication instead of reserved ports for security. Just like rlogin, mrlogin starts a terminal session on a remote host host.

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 mrlogin 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.

-M

The -M option allows an alternate munge unix domain path to be specified.

-P

The -P option allows an alternate service port to be specified.

-V

The -V option outputs the package and protocol version.

A line of the form ``<escape char>.'' disconnects from the remote host. Similarly, the line ``<escape char>^Z'' will suspend the mrlogin session, and ``<escape char><delayed-suspend char>'' suspends the send portion of the mrlogin, 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 mrlogin is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly.

ENVIRONMENT¶

The following environment variable is utilized by mrlogin:

TERM

Determines the user's terminal type.
