48 utility starts a terminal session on a remote host
54 first attempts to use the Kerberos authorization mechanism, described below.
55 If the remote host does not support Kerberos the standard Berkeley
57 authorization mechanism is used.
58 The options are as follows:
61 Use IPv4 addresses only.
63 Use IPv6 addresses only.
67 option allows an eight-bit input data path at all times; otherwise
68 parity bits are stripped except when the remote side's stop and start
69 characters are other than
74 option sets the TCP_NODELAY socket option which can improve interactive response
75 at the expense of increased network load.
79 option stops any character from being recognized as an escape character.
82 option, this provides a completely transparent connection.
86 option turns off all Kerberos authentication.
90 option allows the rlogin session to be run in
98 option turns on socket debugging (see
100 on the TCP sockets used for communication with the remote host.
104 option allows user specification of the escape character, which is
107 This specification may be as a literal character, or as an octal
108 value in the form \ennn.
112 option allows the caller to specify a different local name to be used
113 for authentication. This option is restricted to processes with uid 0.
117 option requests rlogin to obtain tickets for the remote host
120 instead of the remote host's realm as determined by
121 .Xr krb_realmofhost 3 .
125 option specifies a different
127 for the remote login.
128 If this option is not specified, your local username will be used.

138 utilization, but provides
144 disconnects from the remote host.

152 send portion of the rlogin, but allows output from the remote system.
153 By default, the tilde
155 character is the escape character, and
158 is the delayed-suspend character.
160 All echoing takes place at the remote site, so that (except for delays)
164 Flow control via ^S/^Q and flushing of input and output on interrupts
165 are handled properly.
166 .Sh KERBEROS AUTHENTICATION
167 Each user may have a private authorization list in the file
169 in their home directory.
170 Each line in this file should contain a Kerberos principal name of the
172 .Ar principal.instance@realm .
173 If the originating user is authenticated to one of the principals named
176 access is granted to the account.
178 .Ar accountname.@localrealm
183 Otherwise a login and password will be prompted for on the remote machine
186 To avoid certain security problems, the
188 file must be owned by
