rlogin - remote login
rlogin rhost [-ec] [-8] [-c] [ -a] [-f] [-F] [-t termtype] [-n] [-7] [-PN | -PO] [-4] [-d] [-k realm] [-x] [-L] [-l username]
Rlogin connects your terminal on the current local host system lhost to the remote host system rhost.
The version built to use Kerberos authentication is very similar to the standard Berkeley rlogin(1) , except that instead of the rhosts mechanism, it uses Kerberos authentication to determine the authorization to use a remote account.
Each user may have a private authorization list in a file .k5login in his login directory. Each line in this file should contain a Kerberos principal name of the form principal/instance@realm. If the originating user is authenticated to one of the principals named in .k5login, access is granted to the account. If there is no /.k5login file, the principal will be granted access to the account according to the aname->lname mapping rules. (See krb5_anadd(8) for more details.) Otherwise a login and password will be prompted for on the remote machine as in login(1) . To avoid some security problems, the .k5login file must be owned by the remote user.
If there is some problem in marshaling the Kerberos authentication information, an error message is printed and the standard UCB rlogin is executed in place of the Kerberos rlogin.
A line of the form ‘’~.’’ disconnects from the remote host, where ‘’~’’ is the escape character. Similarly, the line ‘’~^Z’’ (where ^Z, control-Z, is the suspend character) will suspend the rlogin session. Substitution of the delayed-suspend character (normally ^Y) for the suspend character suspends the send portion of the rlogin, but allows output from the remote system.
The remote terminal type is the same as your local terminal type (as given in your environment TERM variable), unless the -t option is specified (see below). The terminal or window size is also copied to the remote system if the server supports the option, and changes in size are reflected as well.
All echoing takes place at the remote site, so that (except for delays) the rlogin is transparent. Flow control via ^S and ^Q and flushing of input and output on interrupts are handled properly.
