KAS_INTERACTIVE(8) AFS Command Reference KAS_INTERACTIVE(8)NAMEkas_interactive - Enters interactive mode
SYNOPSIS
kas interactive
[-admin_username <admin principal to use for authentication>]
[-password_for_admin <admin password>] [-cell <cell name>]
[-servers <explicit list of authentication servers>+]
[-noauth] [-help]
kas i [-a <admin principal to use for authentication>]
[-p <admin password>] [-c <cell name>]
[-s <explicit list of authentication servers>+] [-n] [-h]
DESCRIPTION
The kas interactive command establishes an interactive session for the
issuer of the command. By default, the command interpreter establishes
an authenticated connection for the user logged into the local file
system with all of the Authentication Servers listed in the local
/usr/vice/etc/CellServDB file for the cell named in the local
/usr/vice/etc/ThisCell file. To specify an alternate identity, cell
name, or list of Authentication Servers, include the -admin_username,
-cell, or -servers arguments respectively. Interactive mode lasts for
six hours unless the maximum ticket lifetime for the issuer or the
Authentication Server's Ticket Granting Service is shorter.
There are two other ways to enter interactive mode, in addition to the
kas interactive command:
· Type the kas command at the shell prompt without any operation
code. If appropriate, include one or more of the -admin_username,
-password_for_admin, -cell, and -servers arguments.
· Type the kas command followed by a user name and cell name,
separated by an "@" sign (for example: kas admin@abc.com), to
establish a connection under the specified identity with the
Authentication Servers listed in the local /usr/vice/etc/CellServDB
file for the indicated cell. If appropriate, provide the -servers
argument to specify an alternate list of Authentication Server
machines that belong to the indicated cell.
There are several consequences of entering interactive mode:
· The "ka>" prompt replaces the system (shell) prompt. When typing
commands at this prompt, provide only the operation code (omit the
command suite name, kas).
· The command interpreter does not prompt for the issuer's password.
The issuer's identity and password, the relevant cell, and the set
of Authentication Server machines specified when entering
interactive mode apply to all commands issued during the session.
They cannot be changed without leaving the session, except by using
the kas noauthentication command to replace the current
authenticated connections with unauthenticated ones. The
-admin_username, -password_for_admin, -cell, and -servers arguments
are ignored if provided on a command issued during interactive
mode.
To establish an unauthenticated connection to the Authentication
Server, include the -noauth flag or provide an incorrect password.
Unless authorization checking is disabled on each Authentication Server
machine involved, however, it is not possible to perform any privileged
operations within such a session.
To end the current authenticated connection and establish an
unauthenticated one, issue the kas noauthentication command. To leave
interactive mode and return to the regular shell prompt, issue the kas
quit command.
OPTIONS-admin_username <admin principal>
Specifies the user identity under which to authenticate with the
Authentication Server for execution of the command. For more
details, see kas(8).
-password_for_admin <admin password>
Specifies the password of the command's issuer. If it is omitted
(as recommended), the kas command interpreter prompts for it and
does not echo it visibly. For more details, see kas(8).
-cell <cell name>
Names the cell in which to run the command. For more details, see
kas(8).
-servers <authentication servers>+
Names each machine running an Authentication Server with which to
establish a connection. For more details, see kas(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. For
more details, see kas(8).
-help
Prints the online help for this command. All other valid options
are ignored.
EXAMPLES
The following example shows a user entering interactive mode as the
privileged user "admin".
% kas interactive admin
Password for admin: I<admin_password>
