Here is a Quick Start Guide to setup a license server on Linux. There are a lot of links here so my suggestion is to open the URLs in a new tab!
1. Confirm the operating system is supported on Linux for setting up the Network License Manager:
Linux ® 32 or 64 bit on Red Hat® Enterprise Linux 5.0 WS.
It may work with other flavours of Redhat based Linux but we may not support it. i.e. Centos, Fedora, Scientific Linux.

2. . You need download and install the NLM (Network License Manager) Software on the computer /license server:
www.autodesk.com/nlm-ipv4-linux
www.autodesk.com/nlm-ipv6-linux
The file is compressed using .gz and .tar. You can also use Winrar to get you to the final .rpm file.

To install the nlmipv4support_linux32.rpm, run this command to install the software:
su
<enter>
rpm -ivh /path/of/extracted/nlmipv4support_linux32.rpm
3. You will need to obtain the hostname and the ethernet address / MAC address / lmhostid of the computer / license server that will be the Network License Manager.
a. Launch a Terminal Window
b. Go to the directory where lmutil is installed.
cd /opt/flexnetserver
c. Retrieve the host name by entering the following in a Terminal:
./lmutil lmhostid -hostname
d. Retrieve the hostname by entering the following in a Terminal:
./lmutil lmhostid
4. You will need to get your license file for the computer / license server.
a. Login to the Subscription Center and go to Contract Administration > Coverage Report to get your serial numbers:
http://www.autodesk.com/subscriptionlogin

b. Login to Register Once to get your license.
http://www.autodesk.com/register
a. Validate your account information.
b. Enter your serial number.

c. Enter your license server information.

5. Using a Text Editor or vi, create the license file. The default name of the license file and location is:
/var/flexlm/adsk_server.lic
6. To start the license server, you will need to run this command:
a. Launch a Terminal Window
b. Go to the directory where networ license manager is installed.
su
<enter>
cd /opt/flexnetserver
./lmgrd -c /var/flexlm/adsk_server.lic
To check the license server:
./lmutil lmstat -a -c /var/flexlm/adsk_server.lic
7. Typically, for the client computers that need to run Maya or Mudbox, the default name of the file and location is:
/var/flexlm/maya.lic
/var/flexlm/mudbox.lic
The contents of the client file is:
SERVER name-of-server-or-ip-address 0
USE_SERVER
