14) LICENSE SERVER

14.1) Can the lserv License server run on a different subnet than my Network Linda job?

You can run the License server 'lserv' process on a different subnet than your Network Linda job by using the LSHOST environment variable. Set LSHOST to the hostname of the node on which the lserv license server is running.

    eg: etenv LSHOST <hostname>


You can add this to your .login or .cshrc file.

When Ntsnet starts a Network Linda job, it needs to contact the lserv license server to obtain the necessary license tokens. Ntsnet contacts lserv by first looking on the local node, and then by sending a broadcast message on the _local_ subnet. If the lserv license server is on a different subnet the broadcast message will fail. The 3rd method Ntsnet uses to contact lserv, is by using the LSHOST environment variable. If LSHOST is set to the hostname of the node on which lserv is running, Ntsnet sends the license token request directly to that node even if lserv is on a different subnet.
