NAME
rtsetup - Setting up a real time system
DESCRIPTION
Setting up a computer from scratch to run the real time system is
a fairly complex process.
Getting everything
right requires attention to detail and experience with UNIX.
This document outlines the procedure, but lacks sufficient detail
for the inexperienced.
-
Plan the disk configuration. Here's a suggestion:
mountpt |
description |
size |
/ |
os, static software |
3 Gb |
- |
swap |
128 Mb ~ real memory |
/export/home |
all the rest: raid |
-
Get an ip address
-
Install The operating system and latest recommended patches or updates.
-
Install /opt/antelope and /usr/local from a cd.
System File Customization
-
Edit /etc/group to add the rt group; add the line:
rt::140:
-
For security reasons, you may want to install tcp wrappers.
Tcp wrappers restrict certain tcp connnections to hosts specified
in /etc/hosts.allow and not in /etc/hosts.deny.
-
Similarly, you may wish to install sshd, to allow secure connections to
the machine across the network.
-
You may wish to customize the default OpenWindows menus, by editing
the menu files in /usr/openwin/lib/.
-
Setup /etc/ntp.conf to use a local ntp server if possible, or
find a remote clock with which to synchronize.
User Setup
-
Create a home directory for user rt, by creating the directory,
and the entries in /etc/passwd and /etc/shadow. Copy the files
in /usr/local/setup/dotfiles to the new home directory, and change
the ownership of the new directory and dot files using chown -R.
Change the group ownership to rt.
-
Follow the instructions in rtexec_setup(5) to create the directories
and files necessary in the rt home directory.
-
Any additional users must be added by hand: edit /etc/passwd
and /etc/shadow, and create the home directory. Copy the files
from /usr/local/setup/dotfiles into the new directory to provide
initial .lessrc, .login, .logout, .tcshrc, and other initialization
files. Be sure to change the ownership to the new user.
Reboot
At this point, reboot and make sure everything comes up properly,
including the real time system.
-
It might be useful to make backup tapes at this point for each partition.
Set up to perform regular backups as needed.

BUGS AND CAVEATS
There are probably steps left out of this process.
