2 Installing the SDK

NOTE
If you are able to compile the Linux kernel on your host machine, you will also be able to
build the SDK images. Lantronix highly recommends that the machine also act as an
NFS-server.
sudo Configuration
Root permissions are needed for these operations that might need to be performed occasionally:
installation of additional packages on the host
configuring the TFTP- and NFS-servers
creating the target file system so it can be mounted via NFS
If you plan to use the NFS functionality then we recommend making sure that the sudo package
is installed. Configure it so your user can run sudo [command] without having to provide root’s
password. This can be achieved by adding an entry for your login (in the example below: sally) or
for one of the groups you belong to (in the example below: adm) to /etc/sudoers. Beware that this
might be considered a security risk in your organization.
A sample /etc/sudoers could look like this:
# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
# Host alias specification
# User alias specification
# Cmnd alias specification
# Defaults
Defaults !lecture,tty_tickets,!fqdn
# User privilege specification
root ALL=(ALL) ALL
sally ALL=(ALL) NOPASSWD: ALL
# Members of the admin group may gain root privileges
%adm ALL=(ALL) NOPASSWD: ALL
