In particular, some elements of FLEX lm didn't require certain patches, so a v2.4 lmgrd will work successfully with a v2.4b vendor daemon. D.2.2 I've received a new copy of a product from a vendor, and it uses a new version of FLEX lm . Older FLEX lm license files are always valid with newer versions of FLEX lm . As of v3.0, FLEX lm has an optional new format for license files. A server on the Internet will serve licenses to anyone else on the Internet.
Many firewalls require that port numbers be specified to the firewall.
Yes, unless the client's whole system crashes, or becomes disconnected from the network. Assuming communications is TCP, the license is automatically freed immediately. If communications are UDP, then the license is freed after the UDP timeout, which is set by each vendor, but defaults to 45 minutes. UDP communications is normally only set by the end user, so TCP should be assumed. If the whole system crashes, then the license is not freed, and you should use lmremove to free the license.
