49 utility starts a terminal session on a remote host
55 first attempts to use the Kerberos authorization mechanism, described below.
56 If the remote host does not support Kerberos the standard Berkeley
58 authorization mechanism is used.
59 The options are as follows:
62 Use IPv4 addresses only.
64 Use IPv6 addresses only.
68 option allows an eight-bit input data path at all times; otherwise
69 parity bits are stripped except when the remote side's stop and start
70 characters are other than
75 option sets the TCP_NODELAY socket option which can improve interactive response
76 at the expense of increased network load.
80 option stops any character from being recognized as an escape character.
83 option, this provides a completely transparent connection.
87 option turns off all Kerberos authentication.
91 option allows the rlogin session to be run in
99 option turns on socket debugging (see
101 on the TCP sockets used for communication with the remote host.
105 option allows user specification of the escape character, which is
108 This specification may be as a literal character, or as an octal
109 value in the form \ennn.
113 option allows the caller to specify a different local name to be used
114 for authentication. This option is restricted to processes with uid 0.
118 option requests rlogin to obtain tickets for the remote host
121 instead of the remote host's realm as determined by
122 .Xr krb_realmofhost 3 .
126 option specifies a different
128 for the remote login.
129 If this option is not specified, your local username will be used.

139 utilization, but provides
145 disconnects from the remote host.

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