# Setup

Because isectd and the remote execution deamon isdexecd communicate with each other and other programs using TCP/IP there are a few files typically located in the computer's /etc file that should be edited. One is mostly mandatory and the other is optional.

First, the computer that will host the isectd process should be aliased in other computers' /etc/hosts files. When clients try logging on to isectd the function will first look for a host named `isectd'.

If your site doesn't use /etc/hosts but NIS, NIS+, or DNS, contact your network administrator if you want the default login procedure. For security reasons you or your administrator may decide its better for clients to specifically address hostnames rather than making aliases available.

The other file that must be edited is /etc/services. This file keeps track of which ports networking programs listen to. Port numbers below 1024 are reserved for privileged processes. It's important to edit this file (or its NIS equivalent) so that system administrators can avoid port-number conflicts with other programs.

An example from one site:

    #
    # isect services
    #
    isectd	5501/tcp	# isectd
    isdexec	5502/tcp	# isdexecd

Once the system administration tasks are complete, isectd can be started.
