Change the license server to be used by changing an environment variable.
Which license server is used is controlled by an environment variable set in a shell script that is dependant on the type of installation.
In the text files there is a line specifying the ADSKFLEX_LICENSE_FILE environment variable (older thin client releases may use AUTODESK_ADLM_LICPATH). The line will be similar to ADSKFLEX_LICENSE_FILE="@10.11.12.13"
The format of the license server is "[port]@[hostname]" where [port] is optional and only required if the license server administrator has altered the default port. [hostname] can be either an IP address or a full domain name. If you use a full domain name, i.e. mymachine.company.com , ensure the linux command on the client machine host mymachine.company.com resolves to an IP address. It is important to retain the @ symbol to indicate that a network server is required.
