Incidentally, this is where having an ACL is really nice; you can set up your own little "group" anytime you like without dealing with your local BOFH. This isn't much of a problem with a small-scale installation, but it is a royal PITA for a college campus network admin to have to create new groups every time CS101 class partners want to share files among each other and no one else--and, worse, delete them afterwards in a safe way. -- Shimpei Yamashita 山下晋平 <http://www.submm.caltech.edu/%7Eshimpei/> ------------------------------------------------------------------- Next Technical Meeting: October 9 (Sat), 13:30 place: Temple Univ. * Linux Internationalisation Initiative (Li18nux) speaker: Akio Kido * Japanese TrueType Fonts speaker: Adrian Havill Next Technical Meeting: November 13 (Sat), 13:30 place: Temple Univ. * Network Security speaker: Steve Baur Next Nomikai: December 17 (Fri), 19:00 Tengu TokyoEkiMae 03-3275-3691 ------------------------------------------------------------------- more info: http://www.tlug.gr.jp Sponsor: Global Online Japan
