When used with the .Fl 8 option, this provides a completely transparent connection. .It Fl d Turn on socket debugging (see .Xr setsockopt 2 ) on the TCP sockets used for communication with the remote host. .It Fl e Allow user specification of the escape character, which is .Dq ~ by default. This specification may be as a literal character, or as an octal value in the form \ennn. .It Fl i Allow the caller to specify a different local name to be used for authentication. This option is restricted to processes with uid 0. .It Fl l Specify a different .Ar username for the remote login. If this option is not specified, your local username will be used. .El .Pp A line of the form .Dq Ao escape char Ac Ns \&. disconnects from the remote host. Similarly, the line .Dq Ao escape char Ac Ns ^Z will suspend the .Nm session, and .Dq Ao escape\ char Ac Ns Ao delayed-suspend\ char Ac suspends the send portion of the .Nm session, but allows output from the remote system. By default, the tilde .Pq Dq ~ character is the escape character, and normally control-Y .Pq Dq ^Y is the delayed-suspend character. .Pp All echoing takes place at the remote site, so that (except for delays) the .Nm is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly. .Sh ENVIRONMENT The following environment variable is utilized by .Nm : .Bl -tag -width TERM .It Ev TERM Determines the user's terminal type. .El .Sh FILES .Bl -tag -width /etc/hosts -compact .It Pa /etc/hosts .It Pa /etc/hosts.equiv .It Ev $HOME Ns Pa /.rhosts .El .Sh SEE ALSO .Xr login 1 , .Xr rsh 1 , .Xr telnet 1 , .Xr setsockopt 2 , .Xr ruserok 3 , .Xr tty 4 , .Xr hosts 5 , .Xr hosts.equiv 5 , .Xr rlogind 8 , .Xr rshd 8 .Sh HISTORY The .Nm command appeared in .Bx 4.2 . .Pp IPv6 support was added by WIDE/KAME project. .Sh BUGS The .Nm utility will be replaced by .Xr telnet 1 in the near future. .Pp More of the environment should be propagated.
