found possibly Having used Ultrix maybe for a few days total (and that was perhaps five years ago) I'm probably not in the class of user that builds it from sources :-) but I'll try not to let that inhibit me from replying ... The lmf bit of the filename suggests Licence Management Facility to me. DEC never intended this as anything other than a tripwire (at least on OpenVMS) meaning that although you could fairly easily get around it, you'd have a hard time arguing in court that you just typed in something by accident! Giving away the sources would have lowered the "energy barrier" too much, so it was always dropped from the OpenVMS Source Listings distribution. AFAIK, all LMF implementations were based on the same core ideas, so it would have been hard to release the innards on any platform. Antonio
