55 first attempts to use the Kerberos authorization mechanism, described below.
56 If the remote host does not supporting Kerberos the standard Berkeley
58 authorization mechanism is used.
59 The options are as follows:
64 option allows an eight-bit input data path at all times; otherwise
65 parity bits are stripped except when the remote side's stop and start
66 characters are other than
71 option sets the TCP_NODELAY socket option which can improve interactive response
72 at the expense of increased network load.
76 option stops any character from being recognized as an escape character.
79 option, this provides a completely transparent connection.
83 option turns off all Kerberos authentication.
87 option allows the rlogin session to be run in
95 option turns on socket debugging (see
97 on the TCP sockets used for communication with the remote host.
101 option allows user specification of the escape character, which is
104 This specification may be as a literal character, or as an octal
105 value in the form \ennn.
109 option allows the caller to specify a different local name to be used
110 for authentication. This option is restricted to processes with uid 0.
114 option requests rlogin to obtain tickets for the remote host
117 instead of the remote host's realm as determined by
118 .Xr krb_realmofhost 3 .
122 option specifies a different

150 By default, the tilde
152 character is the escape character, and
155 is the delayed-suspend character.
157 All echoing takes place at the remote site, so that (except for delays)
161 Flow control via ^S/^Q and flushing of input and output on interrupts
162 are handled properly.

164 Each user may have a private authorization list in the file

167 Each line in this file should contain a Kerberos principal name of the
