8.1 Invoking

The options are as follows :

`-8'
`--8-bit'
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'
`--no-escape'
`--no-escape'
Stops any character from being recognized as an escape character. When used with the -8 option, this provides a completely transparent connection.

`-K'
`--kerberos'
Turns off all Kerberos authentication.

`-d'
`--debug'
Turns on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host.

`-e'
`--escape=CHAR'
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.

`-k'
`--realm=REALM'
The option requests rlogin to obtain tickets for the remote host in REALM realm instead of the remote host's realm as determined by krb_realmofhost(3).

`-x'
`--encrypt'
Turns on DES encryption for all data passed via the rlogin session. This may impact response time and CPU utilization, but provides increased security.

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, if supported, stop and start the flow of information, flushing of input and output on interrupts are handled properly.

On the server side the iruserok() and ruserok() functions are used to authenticate see the appropriate man page for more information, if supported.
