Setup and Startup
Establishing the VxWorks System Name and Address
The UNIX host system maintains a file of the names and network addresses of
systems accessible from the local system. This database is kept in the ASCII file
/etc/hosts, which contains a line for each remote system. Each line consists of an
Internet address and the name(s) of the system at that address. This file must have
entries for your host UNIX system and the VxWorks target system.
For example, suppose your host system is called mars and has Internet address
90.0.0.1, and you want to name your VxWorks target phobos and assign it address
90.0.0.50. The file /etc/hosts must then contain the following lines:
2
90.0.0.1 mars
90.0.0.50 phobos
Giving VxWorks Access to the Host
The UNIX system restricts network access through remote login, remote command
execution, and remote file access. This is done for a single user with the .rhosts file
in that user’s home directory, or globally with the /etc/hosts.equiv file.
The .rhosts file contains a list of system names that have access to your login. Thus,
to allow a VxWorks system named phobos to log in with your user name and
access files with your permissions, create a .rhosts file in your home directory
containing the line:
phobos
The /etc/hosts.equiv file provides a less selective mechanism. Systems listed in this
file are allowed login access to any user defined on the local system (except the
super-user root). Thus, adding the VxWorks system name to /etc/hosts.equiv
allows the VxWorks system to log in with any user name on the system.
