I just checked the IANA site, and can find no reference to Red Hat stuff in the port numbers list. But there are notices in that list about unoffical port usages, and incorrect and unauthorized port grabs. My motive in this PR was to get similar info into our services file, at least for some of the more egregions cases. In this particular instance, I spent about an hour searching various places before I found that RH had usurped the tacnews port for linuxconf, and that versions of linuxconf were remotely exploitable, which explained the scans. I looked in /etc/services first, of course; if a note had been there, that hour could have been spent elsewhere :-). I am mostly in sympathy with the "anti cruft" attitude, but is info that saves an admin some time or effort really cruft? In any case, the final decision is yours as to what gets distributed with the system; I can always add my own notes to my copy. Thanks for the consideration. -- Dann Lunsford The only thing necessary for the triumph of evil dann@greycat.com is that men of good will do nothing. -- Cicero To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
