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

143 utilization, but provides
149 disconnects from the remote host.

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