uuxqt Daemon

Purpose

Executes Basic Networking Utilities (BNU) remote command requests.

Syntax

uuxqt-e ] [  -sSystemName ] [  -xDebugLevel ]

Description

The Basic Networking Utilities (BNU) uuxqt daemon executes commands on designated remote systems.

The uuxqt daemon on each networked system periodically searches the spool directory for remote execute (X.*) files. These files are sent to the directory by the uucico daemon in response to a uux command.

When it finds X.* files, the uuxqt daemon checks each file to make sure that:

  • All the required data (D.*) files are available.
  • The requesting system has the necessary permissions to access the data files and run the requested commands.

    Note: The uuxqt daemon uses the /etc/uucp/Permissions file to validate file accessibility and command execution permission.

If the data files are present and the requesting system has the appropriate permissions, the uuxqt daemon executes the commands.

Note: The uuxqt command is usually executed from the uudemon.hour command, a shell procedure, and not entered from the command line. You must have root user privileges to issue the uuxqt command from the command line.

Flags

Item Description
-e Enables file expansion.
-sSystemName Designates the remote system to be contacted. Use only when starting the uuxqt command manually. The system name is supplied internally when the uuxqt command is started automatically.

Note: System names can contain only ASCII characters.

-xDebugLevel Displays debugging information on the screen of the local system. The DebugLevel variable is a single digit between 0 and 9, with a default of 5. The higher the DebugLevel variable, the more detailed the debugging information.

Security

Access Control: You must have root authority to start the uuxqt daemon from the command line.

Example

To start the uuxqt daemon for debugging, enter:

/usr/sbin/uucp/uuxqt  -svenus  -x7

This instructs the command to contact remote system venus and provide fairly detailed information about the contact.

Files

Item Description
/usr/sbin/uucp/uuxqt Contains the uuxqt daemon.
/etc/locks Contains lock files that prevent multiple uses of devices and multiple calls to systems.
/etc/uucp/Maxuuxqts Limits remote command executions.
/etc/uucp/Permissions Describes access permissions for remote systems.
/var/spool/uucp/* Contain the execute and data files.
