Remote access to the Vantage workstation enables off-site access to resource consoles. The Vantage administrator can control remote access by creating unique logins and allowing access to specific resources for each login.
The following is a step-by-step procedure for adding remote access users.
1. Login as root and start your system administration program.
2. Add the remote user with the following attributes:
The group name to which the user belongs should be v_ruser
The login shell or start-up program should be /bin/rsh
3. The next task is to create the file system for the new user. All commands should be executed from the root login.
cd /home/[user_name] Changes directory to the new user's directory.
cp -p /home/vanruser/.profile . Copies the .profile file to the new user's directory.
chown [user_name] .profile Changes ownership of the .profile file.
exit Exits the root login.
4. The final step in the setup is to create the .vhost file for the new user. The .vhost file controls which users are allowed to connect to which resources. Refer to Modifying Remote users Files for information on adding vhost files for remote users.
The following is a figure showing the Console Access Technology screen.
Console Access Technology (CAT) Screen
The Console Access Technology screen will be displayed each time the remote user logs in to the Vantage system. Type a resource name after "Enter your Choice:". If the choice entered is valid, the user will see the words V_connect initiated. A configured amount of the resource's console activity will be displayed and they will be able to request read, write or exclusive access to the console. At this point the user has a read only share of the resource's console. To select a mode other that read press CTRL and \ key then enter a choice. Refer to The Shared Console for more information.
To close the shared console, press CTRL and \ key then type q After a brief pause, the user may choose another resource or type quit to exit the program and exit to log off the workstation.
Remote access connection activities are logged to the file /home/vantage/.vlog_[user_name]. For this example the file name for the user sacrem would be /home/vantage/.vlog_sacrem.
Time-out Values for CAT
Time-out values can be set that determine the length of time that users will have to enter a choice before they are logged off the Vantage host. The following discussion explains these values.
The Console Access Technology screen is the user interface that grants access to resource consoles. The CAT screen includes a configurable time-out feature that enables administrators to define the amount of time a user has to enter a choice and the amount of time that will elapse before the user is automatically logged off the workstation. Default values are as follows:
The user will be warned after fifteen minutes of inactivity at the "Enter Your Choice:" prompt that they have two minutes to enter a choice. If no choice is entered, the vconnect program is exited and the user returned to the shell. The user will be warned after 15 minutes of inactivity in the shell that they will be logged off the workstation in one minute. If there is still no activity the user is logged off and the window closed.
Global default time-out values can be set by opening a terminal window, logging in as root and using an editor of your choice to modify the /home/vanruser/.profile file. The section titled "Set up the shell variables:" contains the lines to modify.
The vconnect program accepts two arguments. Argument one defines the amount of time that will elapse before the user is given a warning message that a time-out will occur in "n" seconds. Argument two defines the amount of time that will elapse before the vconnect program is exited and the user is returned to the shell. Values for these arguments are in seconds, therefore, to warn the user after 5 minutes of inactivity and then exit the program 2 minutes later, modify the line to read vconnect 300 120. If a time-out is not desired pass a 0 as either argument one or argument two.
The time-out value for the shell is defined in the variable TMOUT=n. This value defines the number of seconds of inactivity after which the user will be warned that they will be logged off in 60 seconds. When the time elapses the user is logged off and the window closed.
Time-out values can be set for each user individually by logging in as root and modifying the file /home/[user_name]/.profile.
