kas_interactive - Enters interactive mode
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]
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 firstname.lastname@example.org), 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.
-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.
The following example shows a user entering interactive mode as the privileged user "admin". % kas interactive admin Password for admin: I<admin_password> ka>
