llogin(1) General Commands Manual llogin(1)NAME
llogin - Connects to a LAT service
SYNOPSIS
/usr/sbin/llogin -d | service [-p tty] [-H rem_node] [-R rem_port] [-wpassword | -W]
OPTIONS
Displays a list of learned services including the node name and rating. Specifies a local LAT tty device (tty) to use to connect to ser-
vice. Either SVR4 or BSD tty devices can be specified. However, the tty device must already exist and be available for use.
If no tty device is specified, llogin uses any available SVR4 tty device. If no available devices are found, llogin creates an SVR4
LAT tty device for the user. When llogin exits, the created tty device is removed. Specifies a remote host (rem_node) that offers
service. This is helpful when more than one host offers a service. Specifies a remote port (rem_port) that offers service. Speci-
fies a password for connecting to service when the remote service has password checking enabled. The password is not case sensitive
and spaces are not allowed.
If you use the -w option, you specify the password on the command line; it is visible. If you use the -W option, you are prompted
for the password; it is not echoed (visible).
DESCRIPTION
The llogin command enables Tru64 UNIX users to connect to LAT services offered by other nodes in the local area network (LAN). You do not
need superuser privileges or node information in order to connect to LAT services.
If you do not know what services are known to your local node, use the llogin -d command.
If you want to perform simultaneous llogin connections, use the llogin -p command.
To make the llogin connection establishment quicker, add the target hostname as a remote service by using the latcp command.
EXAMPLES
The following command initiates a connection to service siteapp on any node and port through any local LAT tty device: llogin siteapp The
following command initiates a connection to service siteapp on any node and port through local LAT tty device 620: llogin siteapp -p 620
The following command initiates a connection to service siteapp on any remote port on host HOSTX through local LAT tty device 620: llogin
siteapp -p 620 -H HOSTX The following command initiates a connection to service siteapp on remote port TTY_Z on host HOSTX through local
LAT tty device 620: llogin siteapp -p 620 -H HOSTX -R TTY_Z

latsetup(8) System Manager's Manual latsetup(8)NAME
latsetup - Local Area Transport (LAT) setup utility
SYNOPSIS
/usr/sbin/latsetup [-nocurses]
OPTIONS
Specifies that latsetup is run in noncurses and nonmenu-driven mode. Use this option if the terminal you are using does not support curses.
Note that using the latsetup command with the -nocurses option provides limited functionality.
DESCRIPTION
The latsetup command provides an interactive, menu-driven facility for administrating LAT on your system. (For introductory information on
LAT, see the lat_intro(7) reference page.)
To use latsetup, LAT must be built into the running kernel, your system must be at run level 3 or 4, and you must be logged in as supe-
ruser. For more information, see the Network Administration manual.
Note
Running multiple latsetup processes concurrently on the same machine can cause erroneous information to be presented to the latsetup user
and can corrupt the /etc/inittab file.
You can use the latsetup utility to perform the following tasks: Do initial LAT setup Create LAT device special files Add or delete getty
entries to or from the /etc/inittab file Execute init q Start or stop the LAT driver Enable or disable LAT automatic startup and shutdown
If LAT is not configured into the running kernel, latsetup only allows you to remove the LAT entries from the /etc/inittab file.
If you enable LAT automatic startup and shutdown, the /sbin/init.d/lat script starts LAT upon reaching run level 3 and stops LAT upon leav-
ing run level 3.
To run latsetup, log in as superuser and enter the following command: # /usr/sbin/latsetup
Note
LAT is not supported over NetRAIN virtual interfaces or the adapters that compose NetRAIN sets. The latsetup utility does not allow you to
configure LAT over these interfaces, and you should not attempt to do so manually.
In the device creation phase, you choose to create SVR4-style or BSD-style devices. (For an explanation of the types of devices, see the
Network Administration manual.) You should use SVR4-style devices; they allow a larger number of devices.
If you create SVR4 devices using latsetup, and an SVR4 device was mapped as an application port and the device was removed, the port (or
service) information remains associated with the minor number corresponding to the device that was removed. Therefore, when latsetup cre-
ates more devices, it may create the device that was mapped as an application port (if the device name is within the range of SVR4 devices
being created). The latsetup utility does not add a getty entry for the device in the /etc/inittab file. This device is not counted as a
newly created SVR4 device, because it is already being used as an application port.
If you delete SVR4 devices using latsetup, and an SVR4 device was mapped as an application port and has an associated getty entry in the
inittab file, if the device name is within the range of SVR4 devices being removed, latsetup removes the associated getty entry in the
/etc/inittab file. When removing SVR4 devices, latsetup does not remove the device, because it is mapped as an application port. This
device is not counted as an SVR4 device that has been removed.
Note
The latsetup utility creates device names that directly correspond to minor numbers (for example, SVR4 device /dev/lat/620 corresponds to
minor number 620).
Customization
After you run latsetup, you can customize your system's LAT environment by modifying the following files: /etc/inittab
Edit the /etc/inittab file to add any LAT entries. For example, you can add an entry for the LAT/Telnet gateway. For more informa-
tion refer to the guide to Network Administration and inittab(4).
Note
If you delete entries in the /etc/inittab file and then run latsetup to make other changes or deletions, latsetup might not be able
to complete successfully. /etc/latstartup.conf
Create and modify the /etc/latstartup.conf file to include latcp commands to customize your LAT system. This file is read by the
/sbin/init.d/lat script, which executes the commands included in the file. For example, you can change the LAT node name or add
additional service names.
If your system is a member of a cluster, you must create this file as a Context-Dependent Symbolic Link (CDSL). See the System
Administration guide for more information.
For more information refer to the guide to Network Administration and latcp(8).
FILES
Specifies the BSD LAT terminal devices. (Where W is a number from 0 to 9 and X is an alphanumeric character from 0 to 9, a lowercase a to
z, or an uppercase A to Z.) LAT supports up to 620 BSD LAT terminal devices. Specifies the SVR4 LAT device special files. (Where n is a
number starting at 620 and having no upper limit.) Specifies the LAT control device. Specifies the LAT startup and shutdown script.
Specifies LAT customization commands. If your system is a member of a cluster, you must create this file as a Context-Dependent Symbolic
Link (CDSL). See the System Administration guide for more information. Sets up the system database to automatically push the ldterm
STREAMS module on top of the LAT STREAMS driver each time a LAT tty is opened. Controls the initialization process. Specifies the system
configuration file.
