NAME

       kas_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 /etc/openafs/CellServDB file for the
       cell named in the local /etc/openafs/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 /etc/openafs/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>
          ka>

PRIVILEGE REQUIRED

       None
