General Administration Tasks

This section describes:

Configuring the Remote Environment

For a user in a remote non-UNIX environment to be able to use the facilities provided by UNIX-Connect, certain tasks must be carried out in that environment. These tasks are outlined below - for full details see the appropriate system documentation.

Reality Databases

Remote Logon

To allow a user to log onto a remote environment from a Reality database, you must do the following:

Remote File Access

To allow a Reality database user to access files in a remote environment, you must do the following:

Program to Program Communication

If a user needs to use program to program communication, you must use SSM to specify that he or she has remote logon (server) enabled.

Network User-ids

To enable connections to a server to succeed, server-side user-ids and passwords must be configured at the client end. On Windows you should use SSM to enter network user-ids and passwords. On UNIX this is achieved using netadmin.

Note

On a Windows incoming connection, user-ids are validated on the database. On a UNIX incoming connection, user-ids are validated by the operating system.

SovereignX Environment

All system administration tasks on an SX system are carried out in the UNIX environment. See Printer Administration, The ROUTE-FILE, Session Manager and Network Security, and the SovereignX System Administration and Utilities Manual for details.

In order for one SovereignX environment to communicate with another (for instance to use the remote printing facility) local USERS-FILE entries must include a subrecord of the remote environment name with a destination user-id and associated password.

Time Synchronisation

The time on the local UNIX system can be synchronised to that of a remote UNIX system by logging on as root and running the synctime program. This has the following syntax:

synctime systemName {-l userId,password}

where

systemName is the local ROUTE-FILE name for the remote host.

userId is the name of a user on the remote system.

password is the remote user's password.

The -l option and its parameters can be omitted if you have been granted equivalence with a user on the remote system, or if you have a USERS-FILE entry for the remote host.

If the times on the two systems differ by more than 1 second, the local time will be updated. The program will report if the times are already synchronised.

Note

Users other than root can also run the synctime command. In this case, the time settings for the two systems will be reported, but the time on the local system will not be changed.

Environment Variables

The following environment variables can be set globally by the system administrator, or by individual users:

UC_TLI_CONNECT_TO
The UC_TLI_CONNECT_TO environment variable defines the length of time, in milliseconds, for which the UNIX-Connect software will attempt to establish an outgoing connection. This timeout applies only to connections that use the Transport Library Interface (TLI) - it does not apply to X.25 connections.

The default setting of UC_TLI_CONNECT_TO is 12000 milliseconds (2 minutes).

Setting UC_TLI_CONNECT_TO to -1 specfies that the UNIX-Connect software will attempt to establish an outgoing connection indefinitely.

UC_PROCPLID The UC_PROCPLID environment variable determines the PLId format used for daemon processes that do not already have a PLId.
