starts a terminal session on a remote host first attempts to use the Kerberos authorization mechanism, described below. If the remote host does not supporting Kerberos the standard Berkeley authorization mechanism is used. The options are as follows: The 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 option stops any character from being recognized as an escape character. When used with the option, this provides a completely transparent connection. The option turns off all Kerberos authentication. The option allows the rlogin session to be run in ``litout'' (see mode. The option turns on socket debugging (see on the TCP sockets used for communication with the remote host. The 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. The option requests rlogin to obtain tickets for the remote host in realm instead of the remote host's realm as determined by The option turns on encryption for all data passed via the rlogin session. This may impact response time and 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 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 is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly. Each user may have a private authorization list in the file in their home directory. Each line in this file should contain a Kerberos principal name of the form If the originating user is authenticated to one of the principals named in access is granted to the account. The principal is granted access if there is no file. Otherwise a login and password will be prompted for on the remote machine as in To avoid certain security problems, the file must be owned by the remote user. If Kerberos authentication fails, a warning message is printed and the standard Berkeley is used instead. The following environment variable is utilized by Determines the user's terminal type. The command appeared in will be replaced by in the near future. More of the environment should be propagated.
